Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner. Background technique [0002] With the 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 an outdoor high-temperature environment, this heat dissipation method is poor in heat dissipation. The usual method is to reduce the heat generated by the electronic control by reducing the operating frequency of the compressor to ensure the normal operation of the air conditioner. It greatly affects the cooling effect...

Problems solved by technology

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 electronic control to ensure the normal operation of the air conditioner.

It greatly affects the cooling effect of the inverter air conditioner in the case of high outdoor ambient temperature, and affects the comfort of users

The existing technology of using low-temperature refrigerant to dissipate heat from the outdoor unit electric control has the problem of generating condensation water or lowering the temperature of the outdoor unit electric control too low, and in the process of heating and defrosting, it will cause cold and heat shocks to the electric control , affecting the reliability and safety of electronic control

For example, the publication number is CN102844980, and the name is a refrigeration device. Not only the design of the refrigeration system is complicated, the processability is poor, the program control is complicated and the cost is high, it is difficult to form a product

And during the refrigeration cycle, there may be a part of the throttling refrigerant to absorb the heat of the power device, which will cause a large loss of energy efficiency
