Embodiment
Technical scheme provided by the invention is illustrated in more detail with reference to Fig. 1~Fig. 3.
Refrigeration, dehumidifying two operate the refrigerative circle system for all corresponding to air-conditioning.Evaporation required for refrigeration and dehumidifying circulation
Temperature is different.The embodiment of the present invention provides a kind of method for being used to adjust the evaporating temperature of indoor apparatus of air conditioner, and it can be
On the premise of system outdoor unit low pressure is constant, judged such as according to the difference of each place environment temperature of indoor set 1 and dew-point temperature
What individually adjusts the evaporating temperature of each indoor set 1.Referring to Fig. 2 and Fig. 3, central air-conditioning includes outdoor unit 6 and multiple indoor sets 1,
It is independent between each indoor set 1.The adjusting method of the embodiment of the present invention is used for the evaporation temperature for individually adjusting each indoor set 1
Degree.
Above-mentioned adjusting method comprises the following steps：
Whether the environment temperature where step S10, judging indoor set 1 is greater than or equal to dew-point temperature.
Dew-point temperature refers to that air under the conditions of moisture content and air pressure are all immovable, is cooled to temperature during saturation.
Environment temperature is real-time change, can detect environment temperature in real time by detecting element.Generally, for certain
One specific indoor set 1, room where it selects a needs and is dehumidified or freezed, but is not precluded within some cases, the room
It is interior to need advanced row to dehumidify, need to be freezed after a period of time；Or need advanced row to freeze in the room, a period of time
After need to be dehumidified.Not only needed dehumidifying again in the environment that freezes of needs this, first according to environment temperature and dew-point temperature
Relation judge which kind of operation needed to carry out, then before needing to carry out another operation, first by first throttle element 12 and the
Two restricting elements 14 reset, and then carry out another operation again.Possible situation has following two：Dehumidifying-reset-refrigeration, system
Cold-reset-dehumidifying.
If step S20, environment temperature is less than dew-point temperature, reduce the first segment in the liquid pipe 11 of indoor set 1
The aperture of fluid element 12, to reduce the liquid refrigerants amount for the heat exchanger 3 for getting in machine 1.
In above-mentioned step S20, environment temperature is less than dew-point temperature, then illustrates that environment temperature is low, it may occur however that condensation
Phenomenon is, it is necessary to dehumidify.Now, reduce the aperture of first throttle element 12, the liquid of the heat exchanger 3 of the machine of getting in 1 can be reduced
State coolant quantity, it is quick to reduce humidity in room, and air themperature is kept, improve effect on moisture extraction, and certain system can be realized simultaneously
Cold effect.
Further, it is further comprising the steps of in above-mentioned steps S20：If environment temperature is less than dew-point temperature, keep
The aperture of the second restricting element 14 on the tracheae 13 of indoor set 1 is constant.That is, if environment temperature is less than dew-point temperature, subtract
The aperture of first throttle element 12 in the small liquid pipe 11 of indoor set 1 and the second throttling remained on the tracheae 13 of indoor set 1
The aperture of element 14 is constant, to reduce the liquid refrigerants amount for the heat exchanger 3 for getting in machine 1.Which is convenient to carry out, and can essence
Standard grasps the size of adjusted coolant quantity, and then precisely adjusts evaporating temperature.
Further, in above-mentioned steps S20, the aperture of the first throttle element 12 in the indoor set liquid pipe of reduction with
Dew-point temperature is directly proportional to the difference of environment temperature.I.e. dew-point temperature subtract environment temperature difference it is bigger, the interior of reduction
The aperture of first throttle element 12 in machine liquid pipe is also bigger.Conversely, the difference that dew-point temperature subtracts environment temperature is smaller, reduce
The indoor set 1 liquid pipe 11 on first throttle element 12 aperture it is also smaller.
If step S30, environment temperature is greater than or equal to dew-point temperature, reduces the on the tracheae 13 of indoor set 1
The aperture of two restricting elements 14, to reduce the speed that gaseous coolant flows out from the heat exchanger 3 of indoor set 1.
If environment temperature is greater than or equal to dew-point temperature, illustrate that now temperature is higher in room, it is not necessary to dehumidify, Ke Yijin
Row refrigeration.It has been determined that can be by reducing the on the tracheae 13 of indoor set 1 due to central air-conditioning outdoor unit low voltage control
The aperture of two restricting elements 14 so that the coolant quantity in indoor set 1 increases, and the heat absorbed from outdoor unit increases, so as to reach
Reduce the refrigeration of leaving air temp.
It is further, further comprising the steps of in above-mentioned step S30：Remain in the liquid pipe 11 of indoor set 1
The aperture of first throttle element 12 is constant.Even environment temperature is greater than or equal to dew-point temperature, and reduction is located at the tracheae of indoor set 1
The aperture of the second restricting element 14 on the 13 and aperture of the first throttle element 12 remained in the liquid pipe 11 of indoor set 1 is not
Become.Which is convenient to carry out, and can precisely grasp the size of adjusted coolant quantity, and then precisely adjusts evaporating temperature.
In above-mentioned step S30, the aperture and ring of the second restricting element 14 on the tracheae 13 of the indoor set 1 of reduction
Border temperature is directly proportional to the difference of dew-point temperature.That is, environment temperature subtract dew-point temperature difference it is bigger, the indoor set of reduction
The aperture of the second restricting element 14 on 1 tracheae 13 is bigger.Conversely, the difference that environment temperature subtracts dew-point temperature is smaller, subtract
The aperture of the second restricting element 14 on the tracheae 13 of the small indoor set 1 is smaller.
In the room of lowrise layer, for refrigerant from during outdoor unit gets in machine 1, refrigerant gets over flow down, connection
Refrigerant is fewer and fewer in pipe.So, in the case of the standard-sized sheet of unit indoor set 1, bottom floor room often may feel that air-conditioning
All air-out insentience in the case of cooling/heating.At this moment the method provided using above-mentioned technical proposal, can be by reducing the second throttling member
The step number of part 14, to increase refrigerant in indoor set 1.In refrigeration mode circulation, the low temperature liquid refrigerant of indoor set 1 increases, and can lead
Cause leaving air temp to reduce, reach refrigeration.
And, it is necessary to reduce control humidity in damp rooms, while ensure air themperature, reduce the step of first throttle element 12
Number, now the first throttle element 12 of indoor set 1 no longer performs PID control, but is controlled according to the evaporating temperature of indoor set 1, reduces
The liquid refrigerants amount of indoor set 1, blower fan 2 export air quantity it is constant in the case of, after refrigerant evaporation, leaving air temp rise, control evaporation
Temperature is at 13 DEG C or so, and now leaving air temp can remove humid air, also can guarantee that refrigeration at 17 DEG C~19 DEG C.
It can be seen that above-mentioned technical proposal provide more than 1 kinds of evaporating temperature control method of more indoor sets, realize not in chummery not
Equality of temperature moisture requirement, while detection amendment is carried out, meet different air-out demands.
Further, first throttle element 12 includes the first electric expansion valve, and/or, the second restricting element 14 includes the
Two electric expansion valves.Electric expansion valve is easy to control, adjusted, and controls precisely, disclosure satisfy that different degrees of regulatory demand.

Alternatively, the restricting element 14 of first throttle element 12 and second is identical.The parameters such as its model, maximum step number are all one
Sample, so it is easy to integrally-regulated control.
Above-mentioned control method, realized by newly increasing the second restricting element 14.Like this, during refrigeration, refrigerant is advanced
Enter first throttle element 12 throttle after get in the heat exchanger 3 of machine 1, enter back into the second restricting element 14 and throttle, after return to compression
Machine.This is illustrated exemplified by sentencing 480pls electric expansion valve.
Step 1: on unit after electricity, the second electric expansion valve maintains maximum opening 480pls, the first electric expansion valve according to
The degree of superheat of indoor set 1 is controlled, and ensures that indoor set 1 occurs without back liquid phenomenon.
Step 2: air themperature and humidity in detection room, by detecting and being calculated dew-point temperature TL.
Step 3: if environment temperature is greater than or equal to TL, i.e. environment temperature-TL >=0 DEG C, then room need not dehumidify,
It can be freezed.Now outdoor unit low voltage control is fixed, can reduce indoor set 1 by two electric expansion valves of indoor set 1
Evaporating temperature reduces the purpose of the air-out of separate unit indoor set 1 to reach.The step number of the second electric expansion valve can now be reduced, make room
The coolant quantity of interior machine 1 increases, and absorbing heat from outdoor unit increases, and reaches the purpose for reducing leaving air temp.
Step 4: if environment temperature is less than TL, i.e. 0 DEG C of environment temperature-TL ＜, then room needs to dehumidify, and can be made
Cold Dehumidification controlling.Now outdoor unit low voltage control is fixed, can raise indoor set 1 by two electric expansion valves of indoor set 1
Evaporating temperature reaches lifting room temperature, reduces the purpose of humidity.Now the second electric expansion valve continues to maximum step number
480pls, it is possible to reduce the step number of the first electric expansion valve, to reduce the coolant quantity of indoor set 1, make room quickly reduce air wet
