Fig. 3 be show cold-hot water air conditioning system involved in embodiment 1 control device and with the control device it Between carry out input and output constituent element block diagram.Control device 6 has temperature controller and opens/close control member 61, switching structure Part 62 and recovery component 63.Control member 61 is opened/closed to temperature controller based on the water supply inputted from water supply water temperature sensor 5 Temperature and execute temperature controller unlatching/closing usually control and temperature controller unlatching/closing inhibits control, in temperature controller unlatching/closing Usually in control, temperature controller unlatching/closing is repeated with predetermined time interval, inhibits control in temperature controller unlatching/closing In, temperature controller unlatching/closing is executed with the time interval longer than predetermined time interval.Switching member 62 is based on from water supply water temperature The operating frequency of supply water temperature and compressor 103 that sensor 5 inputs, execution are usually controlled from temperature controller unlatching/closing to temperature Control the switching that device unlatching/closing inhibits control.Restore operating frequency of the component 63 based on supply water temperature Yu compressor 103, executes The recovery for inhibiting control usually to control to temperature controller unlatching/closing from temperature controller unlatching/closing.

Next, based on Fig. 4 to the control of the compressor 103 in the cold-hot water air conditioning system when hot water heating operation into Row explanation.The control of compressor when Fig. 4 is the hot water heating operation for showing cold-hot water air conditioning system involved in embodiment 1 The flow chart of movement.Control device 6 is executed and is controlled shown in the flow chart of Fig. 4.

Firstly, control device 6 drives four-way valve 104, the discharge side of compressor 103 is exchanged with water device 102 Connection, and air heat exchanger 101 is connect with the suction side of compressor 103.Then, control device 6 carries out compressor 103 It drives and makes its discharging refrigerant, and recycle the refrigerant in refrigerant circuit.Then, control device 6 makes water-circulating pump 3 Make the water circulation in piping 4 with certain rotation speed rotation, starts the operating of hot water heating.

Later, the temperature that control member 61 starts compressor 103 in step sl is opened/closed to the temperature controller of control device 6 Control device unlatching/closing usually controls.It is detected firstly, the reading of control member 61 is opened/closed to temperature controller by water supply water temperature sensor 5 The water temperature read is then compared by water temperature out with target water temperature, temperature controller unlatching/closing to compressor 103 And operating frequency is controlled.The target water temperature is, for example, the value being set by the remote control operation of user.If by supplying water Water supply water temperature that water temperature sensor 5 detects detection temperature Tm be target water supply water temperature T t-T1 (the 1st temperature difference, such as 0.5deg) hereinafter, then carrying out temperature controller unlatching.On the other hand, if being detected by the water supply water temperature that water supply water temperature sensor 5 detects Temperature Tm is target water supply water temperature T t+T2 (the 2nd temperature difference, such as 2deg) or more, then carries out temperature controller closing.

It is real in the operating that temperature controller unlatching/closing by step S1 usually controls progress in present embodiment 1 Apply the switching determination for inhibiting control towards temperature controller unlatching/closing.Its content is illustrated below.In step s 2, switch structure Part 62 checks whether the operating frequency of the compressor 103 of source heat pump heat machine 1 is minimum frequency (such as 25Hz).If confirmation compression The operating frequency of machine 103 is not minimum frequency, then enters step S3.It is just being transported in compressor 103 with the frequency bigger than minimum frequency In the case where turning, it can be determined that the minimum supply capacity of source heat pump heat machine 1 and being less than the required heat of cold-hot water air conditioning equipment 2 Amount.Therefore, in step s3, cutting for control will be inhibited opening/close from temperature controller usually to control to temperature controller unlatching/closing It changes variable used in judgement and determines that count value Ncount resets to zero.Determine that count value Ncount is to work as to detect the short time When interior temperature controller unlatching/closing switching from plus (increment) 1 variable.Switching member 62 will determine count value Ncount resets to zero.Later, control is back to step S1, continues to open/close control member 61 by temperature controller and executes Temperature controller unlatching/closing usually control.

In step s 2, if the operating frequency of confirmation compressor 103 is minimum frequency, S4 is entered step.In step S4 In, switching member 62 check temperature controller unlatching after within stipulated time TA (the 1st stipulated time, such as 10 minutes) whether Temperature controller closing is carried out.Lead to opening the time interval until temperature controller is closed from temperature controller than stipulated time TA long, i.e. Cross temperature controller open and carry out operating have passed through stipulated time TA or more in the case where, it can be determined that being not in temperature controller Unlatching/closing cycle operation state.Thus, temperature is not carried out within stipulated time TA after temperature controller unlatching if confirming It controls device to close, then enters step S3, will determine that count value Ncount resets to zero.Later, control be back to step S1, continue into Row is opened/is closed temperature controller unlatching/closing that control member 61 executes by temperature controller and usually controls.

In step s 4, temperature controller closing has been carried out within stipulated time TA after temperature controller unlatching if confirming, Then enter step S5.The case where entering step S5 refers to following situation: in the required heat ratio compressor of cold-hot water air conditioning equipment 2 In the state that running ability under 103 minimum frequency is small, temperature has been carried out before from temperature controller unlatching by stipulated time TA Device is controlled to close.In step s 5, check determine whether count value Ncount is zero.Determining that count value Ncount is not zero In the case of, enter step S6.

In step s 6, switching member 62 checks whether have passed through rule from the last time adds 1 to judgement count value Ncount It fixes time TB (the 2nd stipulated time, such as 10 minutes).In step S6 confirmation without the case where stipulated time TB refer to as Lower situation: confirming after time of the temperature controller unlatching until carrying out temperature controller closing is shorter than stipulated time TA, passing through Before stipulated time TB, reaffirm shorter than stipulated time TA from time of the temperature controller unlatching until carrying out temperature controller closing. That is, in the presence of a possibility that carrying out temperature controller unlatching/closing cycle operation is just started.Therefore, S7 is entered step in this case, and 1 is added to judgement count value Ncount.

In step s 6, the case where confirmation have passed through stipulated time TB refers to following situation: confirming from the last time from temperature control Device open time until carrying out temperature controller closing it is shorter than stipulated time TA start, to reaffirm from temperature controller unlatching into Row temperature controller close until time it is shorter than stipulated time TA until, have passed through stipulated time TB.Thus, it is judged to being not in The state of cycle operation is opened/closed to temperature controller.Therefore, S3 is entered step in this case, and switching member 62 will determine to count Value Ncount resets to zero.Later, control is back to step S1, continues to open/close control member 61 by temperature controller and hold Capable temperature controller unlatching/closing usually controls.

On the other hand, in step s 5, if confirmation determines that count value Ncount is zero, the processing of step S6 is skipped, is held The processing of row step S7.In step s 5, there are it is following a possibility that: although the not temperature controller that is just being repeated in the short time Unlatching/closing, but the temperature controller closing within stipulated time TA from temperature controller unlatching is confirmed, positive beginning temperature controller unlatching/ Close cycle operation.Therefore, in this case, the processing without step S6, in the step s 7 to judgement count value Ncount Add 1.

After the processing of step S7, S8 is entered step, switching member 62 checks determine whether count value Ncount is one Determine number or more.The case where determining count value Ncount deficiency certain number is just to be operated in compressor 103 with low-limit frequency Under state, does not generate the case where temperature controller in the short time is opened/closed frequently, be to be not in temperature controller unlatching/closing to follow The case where state of ring operating.In this case, it is usually controlled even if can be judged as and continue temperature controller unlatching/closing, The service life for each component for constituting refrigerant circuit will not be had an impact, in addition will not generate liquid refrigerant to compressor The problem of sucking in 103.Thus, in the case where determining count value Ncount deficiency centainly number, control is back to step S1, continues to open/close temperature controller unlatching/closing that control member 61 executes by temperature controller and usually controls.

On the other hand, determine that count value Ncount the case where reaching certain number refers to following situation: compressor 103 just In the state of being operated with low-limit frequency, is executed repeatedly with stipulated time TA, TB time interval below from temperature controller open respectively It closes to the switching of temperature controller closing and from temperature controller to the switching of temperature controller unlatching.It is opened that is, it is judged that being positive and executing temperature controller Open/close cycle operation.In this case, it is usually controlled if continuing temperature controller unlatching/closing, exists and freeze to composition A possibility that service life of each component in agent circuit has an impact, in addition there is also liquid refrigerant is sucked into compressor 103 Possibility.Thus, switching member 62, which executes usually to control from temperature controller unlatching/closing to temperature controller unlatching/closing, inhibits control Switching.Determine that count value Ncount has reached certain number if confirming, enter step S9, starts opened by temperature controller Temperature controller unlatching/the closing for opening/closing the execution of control member 61 inhibits control.

Above-mentioned step S2~step S8 is the processing step executed by switching member 62, and is just to implement temperature controller Unlatching/closing determines the processing step for inhibiting the switching of control towards temperature controller unlatching/closing during usually controlling.Temperature controller Unlatching/closing control member 61 implements control below.After carrying out temperature controller unlatching, detected when by water supply water temperature sensor 5 When water supply water temperature out detects temperature Tm miss the mark water supply water temperature T t+T2 and its larger difference, temperature controller unlatching/closing control Component 61 makes the operating frequency of compressor 103 rise to improve supply heat.If making source heat pump heat machine 1 by the control Heating efficiency become bigger than the heat dissipation capacity of cold-hot water air conditioning equipment 2, then the water supply water temperature detected by water supply water temperature sensor 5 Temperature Tm is detected to rise.Then, if water supply water temperature detection temperature Tm reaches target water supply water temperature T t, temperature controller unlatching/closing Control member 61 declines the operating frequency of compressor 103 slowly, and maintains the temperature of water supply water temperature, so that source heat pump heat machine The heat dissipation capacity of 1 supply capacity and cold-hot water air conditioning equipment 2 mutually balances.

At this point, if even if the operating frequency of compressor 103 becomes minimum frequency (such as 25Hz), by water supply water temperature sensor The 5 water supply water temperature detection temperature Tm detected still persistently rise and temperature controller is closed, it may be considered that the minimum of source heat pump heat machine 1 Heat dissipation capacity of the minimum supply capacity also than cold-hot water air conditioning equipment 2 when frequency run is big.

If carrying out temperature controller closing, compressor 103 stops, and the supply capacity of source heat pump heat machine 1 is zero.As a result, if by The detection temperature Tm decline of water supply water temperature that water supply water temperature sensor 5 detects and become again target water supply water temperature T t-T1 with Under, then carry out temperature controller unlatching.But even if carrying out temperature controller unlatching, the minimum when minimum frequency of source heat pump heat machine 1 operates Heat dissipation capacity of the supply capacity also than cold-hot water air conditioning equipment 2 is big, therefore carries out temperature controller closing again.That is, in source heat pump heat machine 1 Minimum frequency operating when minimum supply capacity it is bigger than the heat dissipation capacity of cold-hot water air conditioning equipment 2 in the case where, execute with shorter Cycle period temperature controller be intermittently repeated and opens (operating compressor 103 with minimum frequency) and temperature controller and closes (make Compressor 103 stop) temperature controller open/close cycle operation.

The processing of the S2~S8 through the above steps of switching member 62 determines whether to be somebody's turn to do within the regular hour Unlatching/closing cycle operation.

Control is inhibited to be illustrated the temperature controller unlatching executed in step s 9/closing.In temperature controller unlatching/closing suppression In system control, temperature controller is opened/is closed the setting of control member 61 and do not examine the water supply water temperature detected by water supply water temperature sensor 5 Testing temperature Tm is compared with target water supply water temperature T t and forcibly makes the pressure dwell time α of the stopping of compressor 103.It forces Dwell time α is, for example, 10 minutes.Moreover, water supply water temperature detection temperature Tm and target are supplied after forcing dwell time α Water water temperature T t is compared.If water supply water temperature detection temperature Tm be target water supply water temperature T t-T1 hereinafter, if temperature controller unlatching/pass It closes control member 61 and implements temperature controller unlatching.On the other hand, if water supply water temperature detects temperature Tm as target water supply water temperature T t+ regulation Threshold value T3 (the 3rd temperature difference, such as 5deg) or more, then implement temperature controller closing.

Inhibit the pressure dwell time α of the compressor 103 set in control by opening in temperature controller in temperature controller unlatching/closing Starting determines refrigerant temperature when count value Ncount reaches certain number, in compressor 103 (such as compressor in making The 103 sucking degree of superheat) it determines.In other words, temperature is switched to by usually controlling by switching member 62 from temperature controller unlatching/closing Controlling device unlatching/closing inhibits refrigerant temperature when control, in compressor 103 to determine.When the refrigerant temperature is relatively high, Dwell time α is forced to be set relatively long.In addition, inhibiting the reality closed in control to temperature controller in temperature controller unlatching/closing Apply when being judged, for water supply water temperature detection temperature Tm compared with target water supply water temperature T t used in threshold value T3, Start to carry out temperature controller unlatching/closing inhibit after control when confirming temperature controller for the first time and closing, according to forcing in dwell time α The reduction degree of water supply water temperature set.In other words, inhibit in control in temperature controller unlatching/closing, temperature controller is closed dynamic Make point temperature to be corrected based on the reduction degree for forcing the water supply water temperature in dwell time α.Thus, if refrigerant temperature is opposite Height, and dwell time α is forced to be set long, then the reduction degree for the water temperature that supplies water is big, therefore threshold value T3 is set too high.For Dwell time α and threshold value T3 is forced, value appropriate is also different according to the performance of source heat pump heat machine 1, therefore, when forcing to stop Between α and threshold value T3 set based on the practical result for generating the test that cycle operation was opened/closed to temperature controller is carried out.

Also, inhibit in control in temperature controller unlatching/closing, to the water supply water temperature detected by water supply water temperature sensor 5 Detection temperature Tm is compared with water supply water temperature upper limit value Tx, is more than water supply water temperature upper limit value Tx in water supply water temperature detection temperature Tm In the case where, temperature controller is opened/is closed control member 61 and executes the processing for stopping compressor 103.Water supply water temperature upper limit value Tx The setting such as remote controler is utilized by user.Through this process, following situation can be prevented: causing to permit due to water supply water temperature becomes high temperature Perhaps high-temperature water more than ceiling temperature flows into cold-hot water air conditioning equipment 2, and the movement of cold-hot water air conditioning equipment 2 generates undesirable condition.

It is extensive in the operating that the temperature controller unlatching by step S9/closing inhibits control to carry out in present embodiment 1 Multiple component 63 is implemented the recovery usually controlled towards temperature controller unlatching/closing and is determined.The content is illustrated below.In step In S10, restores component 63 and check whether compressor 103 with the frequency higher than minimum operating frequency continuously runs the stipulated time (the 3 stipulated times) (for example, if minimum operating frequency is set as 25Hz, will be set as the stipulated time 60 minutes, then check whether with 26Hz is continuously run 60 minutes).If restoring component 63 confirms that the operating frequency of compressor 103 is low-limit frequency, make control again It is secondary to be back to step S9, continue to open/close temperature controller unlatching/closing inhibition that control member 61 executes by temperature controller Control.

In the case where compressor 103 continuously runs the stipulated time with the frequency higher than minimum operating frequency, can judge Even if the minimum supply capacity for source heat pump heat machine 1 be the heat dissipation capacity of cold-hot water air conditioning equipment 2 hereinafter, implement temperature controller open/ Close usually control, become temperature controller open/a possibility that closing cycle operation is also low.Thus, it enters step in this case S3, restoring component 63 will determine that count value Ncount resets to zero, return step S1, make by temperature controller unlatching/closing control structure The control that part 61 carries out inhibits control usually to control recovery to temperature controller unlatching/closing from temperature controller unlatching/closing.

Here, using Fig. 5 and Fig. 6 to the compressor in the operating condition and present embodiment 1 of existing compressor The difference of operating condition is illustrated.Fig. 5 is compression when showing the hot water heating operation in existing cold-hot water air conditioning system The timing diagram of the operating condition of machine, Fig. 6 are to show hot water heating operation in the cold-hot water air conditioning system involved in embodiment 1 When compressor operating condition timing diagram.The timing of Fig. 5 and Fig. 6 illustrates the minimum supply capacity ratio of source heat pump heat machine Operating condition in the case that the heat dissipation capacity of cold-hot water air conditioning equipment is big.That is, Fig. 5 is shown without involved by present embodiment 1 Temperature controller unlatching/closing inhibit control (processing of above-mentioned step S9) when water temperature variation and compressor 103 operating State.

In the operating of existing compressor 103, usually controlled as shown in figure 5, only executing temperature controller unlatching/closing.By The responsiveness for the water temperature that water supply water temperature sensor 5 detects is fast, and therefore, after temperature controller unlatching soon, water temperature just becomes target It more than water temperature, carries out temperature controller closing (stopping the operating of the compressor 103 of source heat pump heat machine 1).Even if compressor 103 stops Only, water-circulating pump 3 is also still driven and flows recirculated water.Thus, after carrying out temperature controller closing, water temperature shortly becomes It is lower than target water temperature, carry out temperature controller unlatching.That is, compressor 103 carries out temperature controller unlatching/closing cycle operation, source heat pump heat Machine 1 carries out opening/closing operating.

In contrast, in present embodiment 1, if temperature controller unlatching/closing of short time interval reaches stipulated number, inspection It measures temperature controller and opens/close cycle operation, then usually control from temperature controller unlatching/closing to temperature controller unlatching/closing and inhibit Control switching.Inhibit in control in temperature controller unlatching/closing, based on switch to temperature controller unlatching/closing inhibit control when, i.e. temperature The refrigerant temperature such as the sucking degree of superheat of compressor 103 when control device unlatching/closing reaches stipulated number, setting are forced to stop The only time.Moreover, increasing the condition for carrying out temperature controller unlatching by forcing this condition of dwell time.Also, based on strong The temperature of the water supply water temperature generated in dwell time processed reduces, the operating point temperature that the next later temperature controller of amendment is closed.Knot Fruit will not damage the comfort of air reconciliation, can expand temperature controller unlatching/closing time interval, inhibit temperature controller open/ Close number.

It is illustrated to the case where hot water heating operation is carried out in present embodiment 1, even if but being transported in cold water cooling In turning, temperature controller unlatching/closing is also executed with processing step identical with flow chart shown in Fig. 4 and usually controls and is opened with temperature controller Open/close the switching for inhibiting control.In the case where cold water cooling operating, pass through the switching of four-way valve 104, the flowing of refrigerant It is opposite when with hot water heating operation.That is, air heat exchanger 101 plays a role as radiator (condenser), water heat exchanger 102 play a role as heat dump (evaporator), in water heat exchanger 102 flowing water cool down.

Temperature controller unlatching/closing in cold water cooling operating detects in usually controlling by water supply water temperature sensor 5 Water supply water temperature detection temperature Tm be target water supply water temperature T t+T4 (the 1st temperature difference, such as T4=0.5deg) more than when, control Device 6 carries out temperature controller unlatching, is target water supply water in the water supply water temperature detection temperature Tm detected by water supply water temperature sensor 5 Warm Tt-T5 (the 2nd temperature difference, such as T5=2deg) below when, control device 6 carry out temperature controller closing.With with above-mentioned step Slave temperature controller unlatching/closing when the rapid same mode of S2~S8 executes cold water cooling operating usually control open to temperature controller/ Close the switching for inhibiting control.Executed in a manner of same as above-mentioned step S9 cold water cooling operating when temperature controller open/ It closes and inhibits control.The refrigerant temperature of compressor 103 when reaching stipulated number based on temperature controller unlatching/closing is strong to set Dwell time processed.To temperature controller open condition increase have passed through make compressor 103 force stop pressure dwell time this Condition, and risen based on the temperature of the water supply water temperature generated in forcing dwell time, the next later temperature controller of amendment is closed Operating point temperature.

As above, in the cold-hot water air conditioning system involved in present embodiment 1, if the minimum in source heat pump heat machine 1 supplies In the state of being more than heat dissipation capacity or caloric receptivity needed for cold-hot water air conditioning equipment 2 to ability, the temperature control in the short time is detected The interrupted switching of device unlatching/closing, then control device 6 usually controls from temperature controller unlatching/closing and switches to temperature controller unlatching/pass Inhibition control is closed, on the other hand, if detecting the minimum supply capacity of source heat pump heat machine 1 lower than 2 institute of cold-hot water air conditioning equipment The heat dissipation capacity or caloric receptivity needed, then control device 6 inhibits control to switch to temperature controller unlatching/pass from temperature controller unlatching/closing It closes usually control and is operated.Moreover, inhibit in control in temperature controller unlatching/closing, based on being judged to opening in temperature controller The refrigerant temperature of compressor 103 at the time of opening/close the state of cycle operation, setting temperature controller is opened and temperature controller closes The condition closed.Thus, even if source heat pump heat machine 1 minimum supply capacity than cold-hot water air conditioning equipment 2 hot water heat feelings It, also can be in the fortune for considering compressor 103 in the case that the caloric receptivity in the case where heat dissipation capacity or cold water cooling under condition is big Turn to inhibit on the basis of state temperature controller open/close cycle operation.As a result, it is possible to prevent temperature controller unlatching/closing circulation fortune Turn, and the reduction for the oil concentration being able to suppress in compressor 103, is capable of providing efficient and the high life cold-hot water air conditioning system.

In present embodiment 2, the control action of the compressor 103 when hot water heating operation or cold water cooling operate It is identical as flow chart shown in Fig. 4.That is, if the minimum supply capacity in source heat pump heat machine 1 is more than 2 institute of cold-hot water air conditioning equipment In the state of the heat dissipation capacity or caloric receptivity that need, detects the interrupted switching of temperature controller unlatching/closing in the short time, then control Device 6 is usually controlled from temperature controller unlatching/closing is switched to temperature controller unlatching/closing inhibition control.In addition, if detecting heat The minimum supply capacity of heat source machine 1 is pumped lower than heat dissipation capacity needed for cold-hot water air conditioning equipment 2 or caloric receptivity this case, then from Temperature controller unlatching/closing inhibition control is switched to temperature controller unlatching/closing and usually controls.Moreover, in temperature controller unlatching/closing Inhibit in control, control device 6 is based on the compressor being judged as at the time of opening/close the state of cycle operation in temperature controller 103 refrigerant temperature, the condition that setting temperature controller is opened and temperature controller is closed.

Thus, even if in the minimum supply energy for leading to source heat pump heat machine 1 because of the control of the operating frequency of compressor 103 Power is than the heat dissipation capacity in the case where the heating of the hot water of cold-hot water air conditioning equipment 2 or the caloric receptivity in the case where cold water cooling bigger In the case of, can also inhibit in the state of considering the operating condition of compressor 103 temperature controller open/close cycle operation, It can obtain effect same as embodiment 1.

Embodiment 3.

Fig. 8 is the block diagram for showing the outline structure of cold-hot water air conditioning system involved in embodiment 3.For this embodiment party Formula 3 has the hot-water storage tank 9 for being built-in with heat exchanger 8 in the cold-hot water air conditioning system of embodiment 2.Heat exchanger 8 One end the branch pipe 12a of the piping 4 being inserted between auxiliary heater 7 and cold-hot water air conditioning equipment 2 is connected to via piping 12 (branch point), the other end of heat exchanger 8 be connected to via piping 12 be inserted in water-circulating pump 3 and cold-hot water air conditioning equipment 2 it Between piping 4 electric T-shaped valve 11 (point).That is, hot-water storage tank 9 is set via piping 12 relative to cold-hot water air conditioning Standby 2 connect side by side.In addition, being equipped with water temperature sensor 10 in tank in hot-water storage tank 9, water temperature sensor 10 is detected in the tank The water temperature in hot-water storage tank 9 heated by heat exchanger 8.

Control device 6 in present embodiment 3 selects hot water heating operation or cold for example according to the remote control operation of user Any one of water refrigeration operation, hot water supply operating.Control device 6 when hot water heating operation or cold water cooling operate, Electric T-shaped valve 11 is driven as described above, so that water (hot water or cold water) is in source heat pump heat machine 1 and hot and cold water It is recycled between air-conditioning equipment 2.In addition, control device 6 drives electric T-shaped valve 11 when hot water is supplied and operated, so that Hot water is obtained to recycle between source heat pump heat machine 1 and heat exchanger 8.

In present embodiment 3, the movement and hot water supply operating of hot water heating operation or cold water cooling operating The control action of compressor 103 in movement is identical as flow chart shown in Fig. 4, and that as illustrated for embodiment 2 Sample.Thus, even if caused by the control of the operating frequency because of compressor 103 source heat pump heat machine 1 minimum supply capacity ratio The big situation that recepts the caloric in the case where heat dissipation capacity or cold water cooling in the case where the hot water heating of cold-hot water air conditioning equipment 2 Under, can also inhibit in the state of considering the operating condition of compressor 103 temperature controller open/close cycle operation, can Obtain effect identical with embodiment 1 and embodiment 2.
