Abstract

The invention discloses an air conditioner and an electric controller temperature control method thereof. The air conditioner comprises a four-way valve, an indoor heat exchanger and an outdoor throttle component, wherein an indoor throttle component and a controller heat dissipation module is arranged between the indoor heat exchanger and the outdoor throttle component in a series connection manner, a branch path is connected between the four-way valve and the indoor heat exchanger as well as between the indoor throttle component and the controller heat dissipation module, and the branch pathis provided with an air replenishing throttle component. According to the air conditioner and the electric controller temperature control method thereof, by means of the manner that a high-temperature and high-pressure cold medium is mixed with a medium-temperature and medium-pressure cold medium, the temperature of the cold medium entering the controller heat dissipation module is made to rise,electric controller temperature stable control is realized, and electronic controller dew condensation is avoided.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner and a temperature control method of an electric controller thereof. Background technique [0002] During the operation of the air conditioner, the electronic control components will generate heat, and the temperature will affect the operation of the control components. In order to reduce the temperature of the electronic control components and ensure the stable operation of the electronic control components in a relatively safe environment, the electronic control components need to be cooled. At present, the industry uses two typical solutions to cool down the air-conditioning system's electronic controller. The first solution is to install a heat sink behind the electrical box, and use the high-speed wind field generated when the fan is running to transfer the heat from the electrical components to the air, thereby reducing the temperature of the ...
