Single-cooling air conditioner

Abstract

The invention discloses a single-cooling air conditioner comprising a compressor, an outdoor heat exchanger, an electronic control radiator, a first throttle element, and an indoor heat exchanger. The compressor is provided with an exhaust hole and a suction hole. The outdoor heat exchanger is connected with the exhaust hole. The electronic control radiator is provided with a coolant passage. An inlet of the coolant passage is connected with the outdoor heat exchanger. The first throttle element is connected with an outlet of the coolant passage. The indoor heat exchanger is connected with both the first throttle element and the suction hole. The single-cooling air conditioner according to the embodiment is capable of well cooling an electronic control module, so that the single-cooling air conditioner can still operate under high frequency in the high temperature environment; the temperature of coolant entering the electronic control radiator is close to or higher than the outdoor ambient temperature, so that the temperature of the electronic control radiator can be higher than the ambient dew point temperature, and the problem that condensed water affects reliability of the electronic control module is solved basically.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a cooling-only 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 inverter air conditioners, the electronic control 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 to reduce the heat generated by the electronic control module. To ensure the normal operation of the air conditioner, which greatly affects the cool...

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 to reduce the heat generated by the electronic control module. To ensure the normal operation of the air conditioner, which greatly affects the cooling effect of the inverter air conditioner in the case of high outdoor use environment, affecting the comfort of users
