Vortex tube defrosting system for heat pump type passenger car air conditioner system

Abstract

The invention discloses a vortex tube defrosting system for a heat pump type passenger car air conditioner system. The vortex tube defrosting system comprises a reducing tube, a vortex chamber, a compressor, a throttle valve, a defrosting assembly and a cooling assembly. The reducing tube communicates with the vortex chamber. The vortex chamber communicates with a heat pipeline of the defrosting assembly through a vortex heat tube. A control valve is arranged between the vortex heat tube and the heat pipeline. The vortex chamber communicates with a cold pipeline of the cooling assembly through a vortex cold tube. A solenoid valve is arranged on the cold pipeline. An inlet of an evaporator of the defrosting assembly communicates with an outlet of the compressor. An outlet of the evaporator communicates with an inlet of a condenser of the cooling assembly through the throttle valve. An outlet of the condenser communicates with an inlet of the compressor. The outer surface of a passage car evaporator coil is slow in frosting and remarkable in defrosting effect, and the good energy-saving effect and the high economy are achieved; and the prominent problems that when an existing heat pump type passenger car air conditioner system operates in the too low outdoor temperature in winter, the system cannot achieve normal heating, defrosting of an evaporator is frequent, and defrosting is not thorough are solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle air conditioners, and in particular relates to a vortex tube defrosting system for heat pump passenger car air conditioning systems. Background technique [0002] With the rapid development of our country's national economy and the continuous improvement of people's living standards, the bus industry, like other industries, has also achieved rapid development. There are more and more designers of passenger car air conditioners, and the design requirements are getting higher and higher. Many people in other industries are also more and more concerned about the rationality and economy of the defrosting design of the evaporator of the passenger car air-conditioning system. Especially in recent years, the emergence of energy crisis and the continuous improvement of environmental awareness have brought new and more serious challenges to the design of defrosting of passenger car air-conditioning evapor...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the technical problems of the current heat pump air-conditioning system for passenger cars when the outdoor temperature is too low in winter, the system cannot heat normally, the evaporator frequently defrosts and the defrosting is not complete, etc. The vortex tube defrosting system used in the heat pump air-conditioning system of passenger cars is used for heat pump air-conditioning systems in low-temperature environments.
