Abstract

The invention provides a refrigerant heating device and an air conditioner having the same. The refrigerant heating device comprises a circulation device and a thick film heater, wherein the circulation device is provided with a refrigerant flow path and an inlet and an outlet which are communicated with the refrigerant flow path, and the refrigerant flow path is used for the circulation of a refrigerant; the thick film heater is connected with the circulation device, and the thick film heater comprises a thick film circuit and is used for heating the refrigerant in the refrigerant flow path.The technical scheme provided by the invention can solve the problems that the refrigerant heating device in the prior art has a complicated structure and low heating efficiency.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerant heating device and an air conditioner with the same. Background technique [0002] The air conditioner operates under low temperature conditions, and the outdoor unit will be frosted, which will reduce the heating capacity of the air conditioner. Therefore, it is necessary to defrost the outdoor unit of the air conditioner. The existing defrosting methods include refrigeration cycle defrosting and hot gas defrosting. Among them, the refrigeration cycle defrosting is to transfer the system from the heating cycle to the refrigeration cycle through the four-way reversing valve, and the outdoor unit heat exchanger uses its High-temperature refrigerant is used for defrosting; hot gas defrosting is performed by increasing the expansion valve opening to reduce its throttling effect, so that high-temperature refrigerant enters the outdoor unit heat exchanger for de...
