[0063] Such as figure 1 As shown, the air conditioning system 100 is composed of a compressor 1, a first four-way valve 5, a first three-way valve 6, a gas-liquid separator 7, a second four-way valve 8, an outdoor heat exchanger 9, an outdoor fan 10, a first The throttling element 11, the flasher 12, the second throttling element 13, the indoor fan 14, the indoor heat exchanger 15, and the second three-way valve 16 are composed. The interior of the compressor 1 includes a motor 2 , a first cylinder 3 and a second cylinder 4 . The motor 2, the first cylinder 3 and the second cylinder 4 are installed on the same crankshaft. When the rotor of the motor 2 rotates, it drives the rotors of the first cylinder 3 and the second cylinder 4 to rotate, so that the first cylinder 3 and the second cylinder The interior of 4 realizes the compression of the refrigerant gas.

[0064] The second four-way valve 8 has four communication ports, namely a first communication port 8d, a second comm...

[0168] The difference between the second embodiment and the first embodiment is that the first three-way valve 6 in the first embodiment is replaced by other elements, and the overall functions of the air conditioning system 100 remain unchanged.

[0169] Such as Figure 14 shown, is to figure 1 The first three-way valve 6 is replaced by two shut-off valves (the first shut-off valve 17 and the second shut-off valve 18), which can also be realized Figure 1-Figure 13 Various functions of the system described in.

[0170] In this scheme: when the first cut-off valve 17 is closed and the second cut-off valve 18 is turned on, the second connection port 6b and the third connection port 6c are connected, and the first connection port 6a is blocked, which is equivalent to the first The three-way valve 6 is in the first communication state. When the first stop valve 17 is conducting and the second stop valve 18 is closed, the second connection port 6b is blocked at this time, and th...

[0173] The difference between the third embodiment and the first embodiment is that the first three-way valve 6 in the first embodiment is replaced by other elements, and the overall functions of the air conditioning system 100 remain unchanged.

[0174] Such as Figure 15 shown, is to Figure 14 The first cut-off valve 17 in the middle is further replaced by a one-way valve 19, which can also be realized Figure 2-Figure 13 Various functions of the system described in.

[0175] In this scheme: when the second shut-off valve 18 was conducted, the second connection port 6b communicated with the third connection port 6c, and the first connection port 6a was blocked (because the pressure Pm of the flasher 12 was greater than the gas-liquid separation The pressure Ps of the device 7) is equivalent to the first three-way valve 6 being in the first communication state. When the stop valve 18 is closed, the second connection port 6b, the first connection port 6a and the third conne...

Abstract

The invention discloses an air conditioner system. The system comprises a compressor and a reversing valve group; the compressor comprises a first air cylinder and a second air cylinder, the first aircylinder is provided with a first air inlet, a first air outlet and a sliding sheet cavity capable of pressure release, and the second air cylinder is provided with a second air inlet, a second air outlet and a piston cavity capable of pressure release; the reversing valve group comprises a first four-way valve, a second four-way valve, a first three-way valve and a second three-way valve, the first four-way valve is used for correspondingly supplying low-pressure refrigerant and high-pressure refrigerant to the sliding sheet cavity and a first air suction port of the first air cylinder, andthe first three-way valve is used for supplying middle-pressure refrigerant or low-pressure refrigerant to a second air suction port, so that the compressor switches between the independent compression working mode and the variable capacitance compression working mode; the second four-way valve is used for controlling the compressor to switch to the refrigeration mode or the heating mode, and thesecond three-way valve is used for supplying high-pressure refrigerant or low-pressure refrigerant to the piston cavity of the second air cylinder, so that the second air cylinder switches between complete compression participation or part compression participation of the compression cavity.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to an air conditioning system. Background technique [0002] In the related art, a variable capacity compressor is a compressor with two or more compression chambers, typically a rotary compressor with two cylinders. When the cooling load is large, the compressor operates at full capacity (both cylinders work at the same time); when the cooling load is small, the compressor operates at partial capacity (only one of the cylinders works, and the other does not work). The air-conditioning system using the variable capacity compressor can avoid the problems of frequent compressor start-up and stop and partial-load efficiency reduction in the fixed-speed air-conditioning system under partial load, and its SEER (cooling season energy efficiency ratio) is much higher than that of the fixed-speed air-conditioning system. Although it is still lower than the inverter air conditio...
