Enter after mouth 214 in the second cylinder of compressor 210, now, the piston in the second cylinder of compressor 210 is not carried out to refrigerant
Compression.Only the first cylinder of compressor 210 from the refrigerant entered through the first air entry 211 in compressor 210 to being compressed.
It should be noted that no matter air-conditioning system 200 works in refrigeration mode or heating mode, compressor 210 all may be used
To be operated in single cylinder pattern or twin-tub pattern.
In present embodiment, air-conditioning system 200 also includes detecting element 270 and controller 280.Detecting element 270 is used for
The refrigerant pressure of the first valve port 221 is detected to obtain first pressure value P1, and for detect the refrigerant pressure of the 4th valve port 224 with
Obtain second pressure value P2.
Controller 280 is poor for being more than or equal to preset pressure in first pressure value P1 and second pressure value P2 difference P3
During value P4, the second air entry 214 of control connects the first valve port 221 so that compressor 210 is operated in single cylinder pattern, and for the
When one pressure value P 1 and second pressure value P2 difference P3 are less than preset pressure difference P4, the second air entry 214 of control connection the
Four valve ports 224 are so that compressor 210 is operated in twin-tub pattern.
In addition, incorporated by reference to Figure 11, the control method of the air-conditioning system 200 of embodiment of the present invention comprises the following steps:
S10, detects the refrigerant pressure of the first valve port 221 to obtain first pressure value P1;

S30, is more than or equal to preset pressure in first pressure value P1 and second pressure value P2 difference P3 (P3=P1-P2)
During difference P4 (P3 >=P4), the second air entry 214 of control connects the first valve port 221 so that compressor 210 is operated in single cylinder pattern;
And
S40, when first pressure value P1 and second pressure value P2 difference P3 is less than preset pressure difference P4 (P3 < P4),
The second air entry 214 is controlled to connect the 4th valve port 224 so that compressor 210 is operated in twin-tub pattern.
In the control method of above-mentioned air-conditioning system 200 and air-conditioning system 200, by detecting the first valve port 221 and the 4th valve
The refrigerant pressure of mouth 224, to control the mode of operation of compressor 210 so that the efficiency that compressor 210 works is higher, so as to
To improve the operational efficiency of air-conditioning system 200.

When P1 and second pressure value P2 difference P3 is more than or equal to preset pressure difference P4 (P3 >=P4), show air-conditioning system 200
Load is larger, now, and control compressor 210 is operated in twin-tub pattern, and can accelerate refrigerant follows bad speed, to improve air-conditioning system
The cooling and warming speed of system 200, so as to improve the operational efficiency of air-conditioning system 200.
In the related art, the mode of operation of compressor 210 can be controlled by the running frequency of compressor 210, however, needing
It can just obtain switching the critical frequency value of the mode of operation of compressor 210, and different pressures by substantial amounts of experiment test
Contracting machine 210 needs individually to be tested, and cost is than larger.
The pass that present embodiment passes through first pressure value P1 and second pressure value P2 difference P3 and preset pressure difference P4
The mode of operation of system's control compressor 210, cost is relatively low and control process is simple.
In one example, preset pressure difference P4 is 1.5Mpa, when first pressure value P1 is 2.5Mpa, second pressure value
When P2 is 0.6Mpa, due to 2.5-0.6=1.9Mpa > 1.5Mpa, therefore, controllable compressor 210 is operated in twin-tub pattern;
When first pressure value P1 is 1.8Mpa, and second pressure value P2 is 0.4Mpa, due to 1.8-0.4=1.4Mpa < 1.5Mpa, because
This controllable compressor 210 is operated in single cylinder pattern.
It should be noted that in the control method of the manner embodiment air-conditioning system 200, step S10 and S20 can be same
Shi Zhihang is with while obtain first pressure value P1 and second pressure value P2.

Refrigerant pressure as the first valve port 221 refrigerant pressure, and for detecting the refrigerant pressure in second pipe 204 as the 4th valve
The refrigerant pressure of mouth 224.
In this way, the detection first pressure value P1 of detecting element 270 and detection second pressure value P2 mode are easy.For example, inspection
It is, for example, pressure sensor to survey element 270, and two pressure sensors can be separately mounted to the first pipeline 202 and second pipe
On 204, to detect the refrigerant pressure in the refrigerant pressure and second pipe 204 in the first pipeline 202 respectively.
It is appreciated that because the refrigerant in the first pipeline 202 flows directly into the first valve port 221, the outflow of the 4th valve port 224
Refrigerant is directly entered in second pipe 204, therefore, the refrigerant pressure in the first pipeline 202 and the refrigerant pressure of the first valve port 221

Compressor, the compressor can be operated in single cylinder pattern or twin-tub pattern, the compressor be formed with the first air entry,
Exhaust outlet and the second air entry, the compressor include the first cylinder and the second cylinder, first air entry connection described the
One cylinder, second air entry connects second cylinder;
Commutate component, and the commutation component includes the first valve port, the second valve port, the 3rd valve port and the 4th valve port, first valve
Mouth can selectively communicate with second valve port or the 3rd valve port, and the 4th valve port can selectively communicate with described
Second valve port or the 3rd valve port, first valve port connect the exhaust outlet, and the 4th valve port connection described first is inhaled
Gas port, second air entry can selectively connect first valve port or the 4th valve port;
Outdoor heat exchanger and indoor heat exchanger, the first port of the outdoor heat exchanger connect second valve port, the outdoor
The second port of heat exchanger connects the first port of the indoor heat exchanger, and the second port connection of the indoor heat exchanger is described
3rd valve port;With
Throttling arrangement, the throttling arrangement is connected to the second port and the first of the indoor heat exchanger of the outdoor heat exchanger
Between port;
The control method includes step:
The refrigerant pressure of first valve port is detected to obtain first pressure value;
The refrigerant pressure of the 4th valve port is detected to obtain second pressure value;
When the difference of the first pressure value and the second pressure value is more than or equal to preset pressure difference, described the is controlled
Two air entries connect first valve port so that the compressor operating is in the single cylinder pattern;And
When the difference of the first pressure value and the second pressure value is less than the preset pressure difference, control described second
Air entry connects the 4th valve port so that the compressor operating is in the twin-tub pattern.
