Vehicle air conditioning system and vehicle with same

Abstract

The invention relates to the technical field of air conditioners, in particular to a vehicle air conditioning system which comprises a compressor, an out-vehicle heat exchanger, a throttle valve and an in-vehicle heat exchanger which are sequentially connected to form a closed circulation loop, the compressor is connected with the in-vehicle heat exchanger and the out-vehicle heat exchanger through the four-way valve. The two sides or the peripheral wall of an air inlet of the in-vehicle heat exchanger are arranged to be inclined air guide faces, and the inclined air guide faces form a flaringshape. And a forced convection part is not arranged on the out-vehicle heat exchanger. The invention has the following effects: 1, natural convection heat exchange is adopted outside the vehicle, andnatural convection heat exchange is mainly adopted inside the vehicle, so that the noise is obviously lower; 2, natural convection heat exchange is adopted outside the vehicle, and natural convectionheat exchange is mainly adopted in the vehicle, so that the energy-saving effect is remarkable, and the comfort is high; and 3, compared with a traditional bus air conditioner, an outer fan is omitted, an inner fan is also used less, and other parts are all common mature materials, so that operation is stable and reliable, and control, maintenance and management are convenient.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a natural convection heat exchange vehicle air conditioning system and a vehicle. Background technique [0002] In the existing technology, the bus air-conditioning refrigeration and heating are completely relied on natural convection heat transfer, which cannot be realized with the current vapor compression refrigeration technology, and there is no patent in this area at present. At present, the air-conditioning systems on buses and other vehicles basically use copper tube aluminum fin heat exchangers with forced convection, resulting in high noise, high energy consumption, poor comfort, and cumbersome operation control and maintenance management. Contents of the invention [0003] The first purpose of the present invention is to avoid the deficiencies in the prior art and provide a novel vehicle air-conditioning system. Under the premise of cooling and heating in th...
