Energy-saving heat storage heat exchanger

Technical Field

The utility model belongs to the technical field of heat exchangers, and particularly relates to an energy-saving heat storage heat exchanger.

Background

A heat exchanger is a device that transfers a portion of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. The heat exchanger plays an important role in chemical industry, petroleum, power, food and other industrial production, and can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in the chemical industry, so that the application is wide; and a heat storage device which is externally connected with the compressor and is used for storing heat generated in the compressor and storing heat storage materials.

However, in the related art, when frost is adhered to the outdoor heat exchanger during the heating operation of the heat pump air conditioner, the four-way valve is switched from the heating cycle to the cooling cycle to defrost the air. In this defrosting method, although the indoor fan is stopped, there is a disadvantage in that the indoor unit gradually discharges cool air and thus loses the sense of heating.

Therefore, there is an urgent need for an energy-saving heat storage heat exchanger provided in a compressor of an outdoor unit, which uses waste heat of the compressor stored in a heat storage tank during a heating operation to defrost the heat.
