Radiation control method for air conditioner outdoor unit

Abstract

The invention discloses a radiation control method for an air conditioner outdoor unit. An air conditioner comprises an outdoor heat exchanger, an electronic expansion valve, an electronic control radiator and a throttling mechanism. The electronic control radiator is disposed between the outdoor heat exchanger and the throttling mechanism. The electronic expansion valve is disposed between the outdoor heat exchanger and the electronic control radiator. The radiation control method includes: detecting one or more of the temperatures of outdoor unit electronic control, outdoor environment and the outdoor heat exchanger; acquiring the target openness of the electronic expansion valve according to the detected temperature(s), and adjusting the electronic expansion valve according to the target openness. The radiation control method has the advantages that radiation control of an air conditioner outdoor unit is achieved by intelligently adjusting the temperature of the coolant flowing by the electronic control radiator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a method for controlling heat dissipation of an outdoor unit of an air conditioner. Background technique [0002] With the continuous development of air conditioning technology, inverter air conditioners have been widely used in the industry. However, in the outdoor electronic control system of the inverter air conditioner, the inverter module generates a lot of heat, which limits the high-frequency operation of the compressor in a high-temperature environment. Most of the electronically controlled heat dissipation methods currently used are mostly metal heat sinks that dissipate heat through air convection. However, in high-temperature outdoor environments, this heat dissipation method is poor in heat dissipation. The usual method is to reduce the operating frequency of the compressor and reduce the heat generated by the electric control to ensure the normal ope...
