Water-cooled vehicle air conditioning system

Abstract

The invention is suitable to be used in the technical field of vehicle air conditioner, and provides a water-cooled vehicle air conditioning system. The system comprises a refrigerating system and a cold water system. The refrigerating system comprises a compressor, a condenser, an expansion valve, and a plate heat exchanger which are connected in sequence through a refrigerating pipe to form a loop. The expansion valve is assembled on the plate heat exchanger. The plate heat exchanger is arranged on a forecabin region of an entire vehicle. The cold water system comprises a plate heat exchanger, a water pump, and an evaporator which are connected in sequence through a water pipe to form a loop. The cold water system and the refrigerating system perform heat exchange on the plate heat exchanger. In an embodiment of the invention, the plate heat exchanger is arranged on the forecabin, lengths of refrigerating pipes between the condenser and the plate heat exchanger and between the plateheat exchanger and the compressor are shortened, and refrigerating pipe design is simplified, and flow resistance and heat loss of a refrigerating fluid are reduced, and working efficiency of the whole refrigerating system is improved. In addition, the mounting position the expansion valve of the system is changed to the forecabin from the lower part of an instrument desk in a vehicle, and the expansion valve is far away from a cab, so as to reduce influence of noise of the refrigerating fluid on personnel in the cab.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioners and provides a water-cooled automobile air conditioner system. Background technique [0002] In the air-conditioning system, with the current continuous rapid development of my country's automobile industry, after meeting the basic requirements of practicality, safety, reliability and durability of the whole vehicle, the current automobile industry is moving towards more efficient, energy-saving, green, and more Intelligence, humanization and comfort are developing, so the components and systems of the vehicle must also be in line with this general trend, continuously improved and upgraded, and introduced new ones, so as to meet the development needs of the vehicle. [0003] The traditional automotive air-conditioning system uses the vapor compression refrigeration method for temperature adjustment. The main components of the refrigeration system are: compressor, condenser (with...
