Embodiment 1

[0070] Such as figure 1 As shown, the air conditioner 100 runs in the cooling mode. After the temperature sensor 110 detects the outdoor working condition temperature signal of the outdoor heat exchanger 108, the controller performs comparison processing, and the controller detects that the outdoor working condition temperature signal is less than or When the temperature is equal to the preset temperature, the first electronic control valve V1 is controlled to be turned on, and the second electronic control valve V2 is controlled to be turned off. The high temperature and high pressure refrigerant circulating in the first exhaust branch pipe 114 exchanges heat with the low temperature and low pressure refrigerant in the return pipe 112 (Such as Figure 5 to Figure 7 The double dashed arrow shown indicates heat exchange).

Embodiment 2

[0072] Such as figure 2 As shown, the air conditioner 100 is operating in the cooling mode. After the temperature sensor 110 detects the outdoor working condition temperature signal of the outdoor heat exchanger 108, the controller performs comparison processing, and the controller detects that the outdoor working condition temperature signal is greater than the expected temperature signal. When the temperature is set, the first electronic control valve V1 is controlled to be closed, and at the same time, the second electronic control valve V2 is controlled to conduct. The high temperature and high pressure refrigerant circulating in the first exhaust branch pipe 114 does not exchange heat with the low temperature and low pressure refrigerant of the return pipe 112 (such as Figure 5 to Figure 7 The double dashed arrow shown indicates heat exchange).

Embodiment 3

[0074] Such as image 3 As shown, after the conduction mode of the four-way valve 102 is switched, the air conditioner 100 runs in the heating mode. After the temperature sensor 110 detects the outdoor operating temperature signal of the outdoor heat exchanger 108, the controller performs comparison processing. When the controller detects that the outdoor working condition temperature signal is less than or equal to the preset temperature, it controls the first electronic control valve V1 to be turned on, and at the same time, controls the second electronic control valve V2 to be turned off, and the high temperature and high pressure refrigerant flowing in the first exhaust branch pipe 114 Perform heat exchange on the low temperature and low pressure refrigerant in the return pipe 112 (e.g. Figure 5 to Figure 7 The double dashed arrow shown indicates heat exchange).

Abstract

The invention provides an air conditioner, an operation control method and a computer readable storage medium. The air conditioner comprises a four-way valve, an air return pipe and a first exhaust branch pipe, wherein the four ports end of the four-way valve are connected with an indoor heat exchanger, an exhaust port of a compressor, an outdoor heat exchanger and an air return port of the compressor respectively; the first port of the four-way valve can communicate with the air return port of the compressor through the air return pipe; and the second port of the four-way valve can communicate with the exhaust port of the compressor through the first exhaust branch pipe, and high temperature and high pressure refrigerants in the first exhaust branch pipe can conduct heat exchange with backflow refrigerants in the air return pipe. Through the technical scheme, the air return temperature of the compressor can be effectively increased, the exhaust temperature of the compressor is increased, and thus the energy efficiency and reliability of an air-conditioning system are improved.

Description

Technical field [0001] The invention relates to the technical field of household appliances, and in particular to an air conditioner, an operation control method and a computer-readable storage medium. Background technique [0002] As the most important home appliance, the air conditioner is also one of the home appliances that consumes the most power. The main power consumption of the air conditioner lies in the operation of the compressor, that is, the low temperature and low pressure refrigerant is compressed into high temperature and high pressure refrigerant for the next refrigerant cycle. . [0003] In related technologies, if the return temperature of the compressor is too high, it may cause liquid return or oil cooling, and reduce the energy efficiency of the air conditioner. However, the development of more advanced compressors requires a longer development time and more time. Large research and development costs. [0004] Therefore, how to optimize the air conditioner sys...
