An energy-saving and comfortable vehicle air conditioner

Abstract

An energy-saving comfortable vehicle air-conditioner comprises an air-conditioner housing arranged at the roof of a vehicle, and a condenser assembly and an evaporator assembly are arranged inside the air-conditioner housing, wherein the condenser assembly is arranged in front of the evaporator assembly in the forwards-moving direction of the vehicle; the front portion of a condenser cover is provided with arc-shaped diversion holes, and both sides of the condenser cover are provided with bar-shaped air inlet grids. By means of the technical scheme, the energy-saving comfortable vehicle air-conditioner has the advantages that a condenser and an evaporator are integrally designed, a parallel flow heat exchanger employs large units, so that the number of pipe connecting parts and housing fixing positions can be reduced and further the integral structure can be simpler, lighter and more stable; the condenser and the parallel flow heat exchanger are horizontally arranged at forward open angles, the front air inlet surface of the condenser cover is provided with arc diversion members, so that the air inlet uniformity and the heat exchanging efficiency of the condenser can be greatly improved and further energy consumption can be reduced.

Description

technical field [0001] The invention relates to a vehicle air-conditioning system, in particular to a passenger car air-conditioning technology used in large and medium-sized passenger cars with high air quality requirements. Background technique [0002] At present, the traditional vehicle air conditioner is still a split design, with complex structure, heavy weight, large amount of raw materials used, and the eight-shaped design of the condenser, which is far away from the condensing fan, the air flow is unevenly distributed, and the heat transfer capacity of the condensing core is not effective. Play, the return air of the evaporator is directly introduced from the car, the air is dirty, and the humidity is not controlled, causing the ambient temperature and humidity to deviate from the human body comfort curve. [0003] Traditional car air conditioners can only meet the needs of ordinary refrigeration, but now with the improvement of China's economy and people's living s...

Problems solved by technology

[0002] At present, the traditional vehicle air conditioner is still a split design, with complex structure, heavy weight, large amount of raw materials used, and the eight-shaped design of the condenser, which is far away from the condensing fan, the air flow is unevenly distributed, and the heat transfer capacity of the condensing core is not effective. Play, the return air of the evaporator is directly introduced from the car, the air is dirty, and the humidity is not controlled, causing the ambient temperature and humidity to deviate from the comfortable curve of the human body

[0003] Traditional car air conditioners can only meet the needs of ordinary refrigeration, but now with the improvement of China's economy and people's living standards, the demand for a more comfortable and healthier driving environment is increasing, and the development of China's economy has a great impact on energy and resources. The demand is also increasing. The government advocates energy saving and emission reduction. It is extremely important to develop a car air conditioner that is comfortable, healthy, energy-saving and environmentally friendly, and fundamentally change the traditional car air conditioner.
