Problems solved by technology

[0004] However, when the outdoor ambient temperature is too high and the condensation effect of the outdoor heat exchanger is not good, the temperature of the refrigerant is high. Even if the solenoid valve needs to be opened to cool down the frequency conversion control module, the cooling effect is not good, which seriously affects the frequency conversion control. Reliability of modules and air conditioners

Abstract

The invention provides an air-conditioner, a running control method and a running control device. The air-conditioner comprises a radiating bypass and a second orifice union, the radiating bypass is connected with a refrigerant channel between an outdoor heat exchanger and a first orifice union in parallel, and is used for radiating a frequency converting control module, and the second orifice union is arranged at the inlet end of the radiating bypass and is used for regulating and controlling the temperature value of a refrigerant flowing in the radiating bypass. By means of the above technical scheme, the cooling effect on the frequency converting control module is optimized, and the running reliability of the air-conditioner under the extreme environment is improved.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner, an operation control method and an operation control device. Background technique [0002] When the inverter air conditioner is running in cooling mode, multiple power transistors in the inverter control module may generate a large amount of heat, which poses a great challenge to the reliability of the inverter control module. [0003] In related technologies, it is usually necessary to set up a cooling bypass near the frequency conversion control module. The conduction of the cooling bypass is controlled by a solenoid valve. The frequency conversion control module cools down, and when the frequency conversion control module does not need to cool down, the solenoid valve is closed. [0004] However, when the outdoor ambient temperature is too high and the condensation effect of the outdoor heat exchanger is not good, the temperature of the refrigerant ...
