Problems solved by technology

Since the suction of the two-stage compression (status point 3) is in an overheated state, it will cause the two-stage compression to deviate from the isentropic compression process, which will increase the power consumption of the compressor and increase the exhaust temperature
In addition, in system matching, due to differences in refrigerant charge and operating conditions, the suction state of the high-pressure compressor 101 may be in a full liquid state or a gas-liquid mixed state, which may easily cause compressor liquid shock

Abstract

The present invention provides an air conditioning system, comprising a compressor, a condenser, a first throttling device, a flash evaporator and an evaporator, and the compressor, the condenser, the first throttling device, the flash evaporator and the evaporator are connected in sequence to form a refrigeration cycle , the compressor includes a low-pressure stage compressor and a high-pressure stage compressor, the suction end of the low-pressure stage compressor is connected to the first port of the evaporator, the second port of the evaporator is connected to the second port of the flasher, and the first port of the flasher The first throttling device in series is connected to the first port of the condenser, the second port of the condenser is connected to the exhaust end of the high-pressure stage compressor, and the suction end of the high-pressure stage compressor is connected to the third port of the flasher; the low-pressure stage compressor The exhaust end of the outlet is connected to the first port of the flasher or to the third port of the flasher or to the fourth port of the flasher. It also relates to a compressor. It makes the two-stage compression closer to the isentropic compression process and avoids the liquid hammer phenomenon of the compressor.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to an air conditioning system and a compressor. Background technique [0002] Existing conventional two-stage enthalpy-enhancing compressors are used in air-conditioning systems, such as figure 1 As shown, the air conditioning system includes a high-pressure compressor 101, a low-pressure compressor 102, a four-way valve 103, a condenser 104, a stop valve 105, a flash evaporator 106, and an evaporator 107. The low-pressure compressor 102 compresses (one-stage compression) The final superheated steam (state point 2) is mixed with the saturated steam (state point 6) drawn from the flash evaporator 106, and the mixed state is a superheated state, and enters the suction end of the high-pressure stage compressor 101 (two-stage compression), and the air conditioner The lgp-h diagram of the system in cooling operation is as follows figure 2 Shown, where the numbers 0, 2, 3, 4, 5, 6, 7, 8 repre...
