Abstract

The invention discloses a heating and cooling air conditioner comprising a compressor, a four-way valve, an outdoor heat exchanger, an electrical control system, a first throttling element, an indoor heat exchanger, a one-way valve, a second throttling element and a controller. The second throttling element and the controller have an adjusting function. The electrical control system comprises an electrical control module and an electrical control radiator. The electrical control radiator has a refrigerant passage, and one end of the refrigerant passage is connected to the outdoor heat exchanger. The first throttling element is connected to the other end of the refrigerant passage. The one-way valve is connected to the outdoor heat exchanger and the first throttling element and is communicated in a one-way manner in the direction from the first throttling element to the outdoor heat exchanger. The controller controls the second throttling element to adjust the flow of refrigerant entering the electrical control radiator. According to an embodiment, in the refrigeration cycle, good cooling effect can be performed on the electrical control module, and the problems that reliability of the electrical control module is influenced through condensate water can be further solved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a heating and cooling 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 t...
