Problems solved by technology
The disadvantages of the water-cooling integrated automotive air-conditioning system of this structure are: (1), since two evaporators (i.e. double steaming) are used, and the two evaporators are refrigerated by refrigerant, the air-conditioning pipeline is relatively Long, the air conditioning system uses a large amount of refrigerant, so the cost is high; (2), the rear evaporator is large in size and thick in thickness, and it is placed on the roof of the car, which affects the sight of passengers in the car

The invention discloses a water / coolant integrated automobile air conditioning system, and relates to a refrigerating device. The water / coolant integrated automobile air conditioning system comprises a coolant system and a water cooling system, wherein the coolant system comprises a coolant compressor, a condenser, a dryer, an expansion valve and a front evaporator which are sequentially connected to form a loop, an exchanger with a coolant channel and a water cooling channel simultaneously is arranged inside a primary heat radiating fin of the front evaporator, the input and the output ends of the coolant channel are respectively connected with the expansion valve and the coolant compressor; the water cooling system comprises a water pump and a water-cooling exchanger serving as a rear refrigerating device, and the water pump and the water-cooling exchanger are connected with the input and the output ends of the water cooling channel of the front evaporator to form a water-cooling circulation loop. By omitting the traditional rear evaporator, the system disclosed by the invention can not only has greatly reduced consumption of the coolant, but also has reduced number of air conditioning pipelines so that the cost is reduced remarkably, besides, the system has the characteristics of small occupied space, convenience for the arrangement, widened vision of passengers in an automobile and superior air conditioning effect, and can be easily popularized and applied among manufacturers of automobile air conditioners.
Description
technical field [0001] The invention relates to a refrigeration device, in particular to an air-conditioning system for automobiles. Background technique [0002] Due to the large interior space of passenger cars and mini-cars, in order to meet the cooling requirements of the second and third rows of passengers, the traditional air-conditioning systems of passenger cars and mini-cars are composed of front evaporators and rear evaporators. The dual-evaporator air-conditioning system, that is, the front evaporator meets the cooling needs of the first row of passengers, and the rear evaporator is used to meet the cooling needs of the passengers in the second row and beyond. The disadvantages of the water-cooling integrated automotive air-conditioning system of this structure are: (1), due to the use of two evaporators (i.e. double steaming) at the front and rear, and the two evaporators are all cooled by refrigerant, the air-conditioning pipeline is relatively Long, the air-co...
