Refrigerant heating devices and air conditioners

Abstract

The invention provides a refrigerant heating apparatus and an air conditioner. The refrigerant heating apparatus is easy to manufacture and produce and has reliability guaranteed; the convective heat transfer coefficient between the refrigerant heating apparatus and a refrigerant is increased while the heat transfer effect is good. The refrigerant heating apparatus comprises a casing, an electric heating pipe and a refrigerant inlet pipeline; the casing is provided with a refrigerant inlet, a refrigerant outlet and an electric heating pipe mounting port; the electric heating pipe extends into an inner cavity of the casing through the electric heating pipe mounting port and a power supply terminal of the electric heating pipe is disposed outside the casing; the refrigerant inlet pipeline is connected with the casing at the position of the refrigerant inlet; an included angle A which is larger than or equal to 60 degrees and smaller than or equal to 90 degrees is formed between the center line of a joint section between the refrigerant inlet pipeline and the casing and the center line of the electric heating pipe. The air conditioner comprises a compressor, a condenser, an evaporator, a throttling device, a refrigerant circulation pipeline and the refrigerant heating apparatus, wherein the refrigerant inlet pipeline and the refrigerant outlet of the refrigerant heating apparatus are respectively connected with the refrigerant circulation pipeline.

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. Background technique [0002] The air conditioning and refrigeration system is mainly composed of four basic components: compressor, condenser, evaporator, and throttling device. They are connected in turn by pipes to form a closed system, and the refrigerant circulates continuously in the system, exchanges heat with the outside world and undergoes state changes. [0003] Usually, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure, and the outdoor unit blows hot air; then the refrigerant passes through the throttling device, Entering the evaporator (indoor unit), because the space of the refrigerant from the throttling d...

AI Technical Summary

Problems solved by technology

The existing refrigerant heating method is complex and difficult to manufacture and process, and the surface temperature of the heating element cannot be controlled when the state of the refrigerant (such as flow rate, temperature, etc.) is abnormal, which will cause the surface temperature of the heating element to exceed the use range, and even cause the occurrence of the heating medium. Harmful phenomena such as pyrolysis, carbonization and deterioration, reliability cannot be guaranteed
