The specific embodiment
Below, with reference to accompanying drawing embodiments of the invention are described.
(embodiment 1)
Fig. 1 has represented the embodiment 1 of air-conditioner of the present invention, the connection status when especially expression system warms up running.
Air-conditioner of the present invention has off-premises station 2, indoor set 4 and temporary location 6, interconnects to constitute refrigerant loop circlewise.
Off-premises station 2, by the compressor 8 that is used for compressed refrigerant (primary coolant), be used to carry out the outdoor heat converter 10 of the heat exchange between outdoor air and cold-producing medium, as the electric expansion valve 12 of the throttling arrangement of cold-producing medium, be used to switch the loop direction of cold-producing medium cross valve 14, be used to control the outdoor control device 16 of off-premises station 2 and be used for constituting to the outdoor fan 18 of outdoor heat converter 10 supply chamber outer air.
On the other hand, off-premises station 4 is by the indoor heat converter 20 that carries out the heat exchange between room air and cold-producing medium, be used for constituting to the Indoor Control Device 24 that indoor heat converter 20 is supplied with the indoor fan 22 of room airs and is used to control indoor set 4.
In addition, temporary location 6, by the intermediate heat exchanger 26 that is used for carrying out the heat exchange between primary coolant and secondary refrigerant, be used for switch control cold-producing medium the electric switching valve 28 that flows, as the electronic adjustment valve 30 of the middle throttling arrangement of cold-producing medium, be used to stockpile secondary refrigerant surge tank 32, be used to make the middle control device 36 that stockpiles the pump 34 that the secondary refrigerant at surge tank 32 circulates and be used to control temporary location 6 to constitute.Electric switching valve 28 and electronic adjustment valve 30 are connected in parallel between indoor heat converter 20 and the intermediate heat exchanger 26 to constitute decompressor.In temporary location 6, in intermediate heat exchanger 26,,, make warm at hot water ground panel 38 as the secondary refrigerant end by pump 34 through surge tank 32 by carrying out the secondary refrigerant of for example hot water that heat exchange obtains etc. with primary coolant.
When the warm running of system of the air-conditioner of the present invention of above-mentioned formation, the cold-producing medium by compressor 8 is discharged flows along the direction shown in the arrow A through cross valve 14, flows into indoor sets 4 through temporary location 6, flows into off-premises station 2 again and is back to compressor 8.
Below, warm up and describe based on the system of indoor set 4 carrying out simultaneously based on the warm situation of the ground system of hot water ground panel 38.
Refrigerant gas from the HTHP of discharging with the outlet of the compressor 8 that is rotated of revolution of regulation, when the warm running of system, in intermediate heat exchanger 26, dispel the heat and give the water that circulates by pump 34, part of refrigerant condensation of gas and from intermediate heat exchanger 26 outflows through cross valve 14.Cold-producing medium from intermediate heat exchanger 26 flows out flow in the indoor heat converter 20 of indoor set 4 by electric switching valve 28 or electronic adjustment valve 30.In indoor heat converter 20, cold-producing medium further heat radiation is given the room air of being supplied with by indoor fan 22, and almost the state with liquid is back to off-premises station 2.Be back to the cold-producing medium of off-premises station 2, be depressurized in electric expansion valve 12, the outdoor air heat absorption from being supplied with by outdoor fan 18 in outdoor heat converter 10 is sucked into compressor 8 through cross valve 14 again.
At this moment, the pressure of the cold-producing medium of intermediate heat exchanger 26 is the force value identical with the discharge pressure of compressor 8.In addition, refrigerant pressure as the outdoor heat converter 10 of evaporimeter, decide by the temperature of outdoor air and humidity, the air quantity of outdoor fan 8, the heat exchange performance of outdoor heat converter 10 etc., become and than the outside air temperature corresponding force value of saturation temperature in low several years.
At this, if consider to open the situation of electric switching valve 28, the state that all is equal to nothing of electric switching valve 28 and electronic adjustment valve 30 then, the refrigerant pressure of the refrigerant pressure of intermediate heat exchanger 26 and indoor heat converter 20 is about equally.Thereby if the revolution of compressor 8 rises, then the discharge pressure of circulating mass of refrigerant and compressor 8 rises, and along with the rise refrigerant temperature of indoor heat converter 20 of hot water temperature also rises, can generally increase thermal discharge.But, in this case, can not arbitrarily adjust the thermal discharge balance of intermediate heat exchanger 26 and indoor heat converter 20.That is, the air quantity of the temperature of room air and indoor fan 22 is identical, if the condition of hot water ground panel 38 and indoor set 4 is certain, then can not arbitrarily change the balance of the thermal discharge of intermediate heat exchanger 26 and indoor heat converter 20.
At this, if close electric switching valve 28, reduce the aperture of electronic adjustment valve 30, then the refrigerant pressure of intermediate heat exchanger 26 rises, and the refrigerant pressure of indoor heat converter 20 refrigerant pressure and the centre of the refrigerant pressure of outdoor heat converter 10 corresponding with the aperture of electronic adjustment valve 30, that be set at intermediate heat exchanger 26 are located.In addition, the ability along with the pressure indoor set 4 that reduces indoor heat converter 20 also reduces.
Generally when system is warm, preferably do not have the state of air-flow, ideal is mainly to utilize hot water ground panel 38, and auxiliary makes warm with indoor set 4.And even the refrigerant pressure of indoor heat converter 20 is not high, indoor set 4 also can be exported by adjusting air quantity, if but hot water ground panel 38 do not improve the refrigerant pressure of intermediate heat exchanger 26 then can not obtain essential surface temperature.
Thereby, preferably intermediate heat exchanger 26 is configured in the upstream side of easy collection high temperature.
Like this, by intermediate heat exchanger 26 is configured in upstream side, and between indoor set 4 and intermediate heat exchanger 26, connection configuration electric switching valve 28 parallel with one another and electronic adjustment valve 30, can access face panel 38 necessary temperature hydrothermally, simultaneously, also can arbitrarily set the ability of indoor set 4.Thereby the room temperature when improving the warm running of system is controlled with surface temperature, can carry out comfortable system and warm up.
In addition, Indoor Control Device 24, middle control device 36, and outdoor control device 16 between when communicating, if Indoor Control Device 24 communicates with outdoor control device 16 through middle control device 36, then middle control device 36 can be known the state of indoor set 4 easily.So, can further improve controlled that system warm based on the system of indoor set 4 and based on hot water ground panel 38 warms up, realize that more reliably comfortable system warms up state.
In addition, cold for fear of the underfooting when carrying out cooling operation, preferably do not use hot water ground panel 38, and only utilize indoor set 4 to freeze.Electric switching valve 28 and electronic adjustment valve 30, owing to only be to produce pressure loss when cooling operation, so preferably open.And,, then can suppress the consumption in vain of electric power if open when electric switching valve 28 is set at no power.
Thereby, when cooling operation, stop after the pump 34, if open electric switching valve 28, electronic adjustment valve 30 no powers use with the state of opening, then suppress pressure loss, and reduce consuming electric power in vain, carry out cooling operation even therefore have temporary location 6 also can not can to diminish the lost territory economically.
In addition, even selecting indoor set 4 separately under the situation of the warm running of system, also with cooling operation in the same manner after stopping pump 34, open electric switching valve 28, and electronic adjustment valve 30 no powers use with the state of opening, and can suppress pressure loss, and minimizing consumes electric power in vain.
In addition, when beginning is warm based on the indoor set 4 and the system of hot water ground panel 38, that is,, the little indoor temperature of thermic load when starting is risen from the viewpoint of the warm performance of quick system.That is, after stopping pump 34 or suppressing the internal circulating load of secondary refrigerant, electric switching valve 28 uses with the state of opening with electronic adjustment valve 30 no powers, and indoor set 4 is made warm running separately.In view of the above, can not can lose the warm toggle speed ground of economy and system and make warm running.
In addition, as shown in Figure 1, on the refrigeration pipe arrangement of indoor set 4, be provided as the indoor tube temperature sensor 40 of the 1st temperature-detecting device.The position of indoor tube temperature sensor 40 can be the inlet of the indoor set 4 of the warm circulation of system, also can be at indoor heat converter 20 midway.
It is warm to start system, if the relative desired value of room temperature reaches the indoor value of rule, then electric switching valve 28 is closed, with aperture 24 that send here from Indoor Control Device, by indoor tube temperature sensor 40 detected pipe arrangement temperature or the electronic adjustment valve 30 of the corresponding adjustment of condensation temperature.For example, under the situation of the ability that does not reduce indoor set 4, control electronic adjustment valve 30 throttlings, make the detected temperatures of indoor tube temperature sensor 40 drop to suitable value, on the other hand, under the situation of the ability that does not increase indoor set 4, control electronic adjustment valve 30 and open, make the detected temperatures of indoor tube temperature sensor 40 rise to suitable value.In view of the above, can improve the control accuracy of electronic adjustment valve 30, simultaneously, can realize the warm state of comfortable system in the precision highland.
In addition, the exit of the temporary location 6 in the warm circulation of system is provided with the middle pipe arrangement temperature sensor 42 as the 2nd temperature-detecting device.At this, because if consider to carry out only warming up based on the system of hot water ground panel 38 situation of running, then indoor set 4 is " pass ", so, do not produce the information that signal of communication just can not obtain indoor set 4.In this state, according to operating condition, the also high cold-producing medium of flowing temperature sometimes in indoor heat converter 20 is trapped in the roof side and might influences comfortableness in indoor generation free convection or warm air.In this case, if adjust the aperture of electronic adjustment valve 30 so that make the pipe arrangement temperature that obtains by middle pipe arrangement temperature sensor 42 lower than the temperature of regulation, even then do not obtain communication data, can adjust electronic adjustment valve 30 accurately yet from indoor set 4.Its result, the refrigerant temperature that flows in indoor set 4 and the temperature difference of room air diminish, and suppress the generation of free convection, and can realize that the few comfortable system of air-flow is warm.
And, when indoor set 4 stops, can preventing to discharge unwanted heat by indoor set 4, improve the thermal efficiency.
In addition, in air-conditioner of the present invention, make communication data form between Indoor Control Device 24 and the middle control device 36 and middle control adorn 36 and outdoor control device 16 between the communication data form identical, middle control device 36 will be rewritten from the part of the communication data of Indoor Control Device 24, make it become communication form to outdoor control device 16 transmission.For example, if certain Capability Requirement of output Indoor Control Device 24, after 36 pairs of middle heat exchanger 26 essential abilities of then middle control device add computing and rewrite the Capability Requirement value, the outdoor restraining device 16 of posting a letter.Off-premises station 2 is only accepted essential ability value as information, needn't consider that off-premises station 2 is directly to be connected with indoor set 4 or to be connected through temporary location 6, with regard to the rotating speed of controlled system compressor 8.Thereby,, just can in multiple the setting, connect temporary location 16, and can realize diversified formation easily as long as similarly indoor set and off-premises station are provided with the communication data form.
