Abstract

The invention provides a refrigerant heating device. The refrigerant heating device comprises a refrigerant outer tube (1), a heating portion and spiral fins (18); the refrigerant outer tube (1) comprises a first inner chamber, the refrigerant inlet (5) and the refrigerant outlet (9); the heating portion is at least partially arranged in the first inner chamber; the spiral fins (18) are arranged on the outer wall of the heating portion in a sleeved mode; the inner wall of the refrigerant outer tube (1), the spiral fins (18) and the outer wall of the heating portion are formed into a spiral refrigerant channel from the refrigerant inlet (5) to the refrigerant outlet (9) commonly. The refrigerant heating device and an air conditioner with same effectively solve the problem that the heating efficiency of refrigerant heating devices is low in the prior art.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a refrigerant heating device and an air conditioner with the refrigerant heating device. Background technique [0002] Frost is the main reason that threatens heat pump air conditioners in winter. When the outdoor ambient temperature of the heat pump air conditioner is lower than 0°C, within the limited defrosting time, the output heat of the whole unit itself is not enough to melt the frost on the evaporator, so additional heat is needed to defrost . At present, the method of directly heating the refrigerant with an electric heater is widely used, and the electric energy is converted into heat energy of the refrigerant through the refrigerant heating device installed on the pipeline, thereby increasing the heat output of the unit and improving the efficiency and energy efficiency of defrosting. [0003] The refrigerant heating device in the prior art has an outer pipe through w...
