Vehicle air conditioning system with waste heat recovery function

Abstract

The invention belongs to the field of vehicle air conditioners, in particular to a vehicle air conditioning system with a waste heat recovery function. The vehicle air conditioning system comprises atwo-way ventilation module and a waste heat recovery module, wherein the two-way ventilation module comprises an external air passage of a vehicle body (1), an air exchange passage in a vehicle (2), aone-way air inlet fan (3), a one-way air outlet fan (4), an air-out loading channel (401) and an air-out feeding channel (402), and the waste heat recovery module includes a refrigerant heat exchangeassembly (5), a hydraulic pump (6), a heat exchange assembly (7) and a power turbine (8); the end port of a liquid distributor of the refrigerant heat exchange assembly (5) is connected to the heat exchange input end port of the heat exchange assembly (7) through the hydraulic pump (6); and the heat exchange output end port of the heat exchange assembly (7) is connected to an entrance of the power turbine (8). The vehicle air conditioning system with the waste heat recovery function has high heat conversion efficiency, low manufacturing cost and low energy consumption, high heat exchange speed, and can realize air supply from the outside of a vehicle compartment to the interior of the vehicle compartment and air discharge from the inside of the vehicle compartment to the outside of the vehicle compartment.

Description

technical field [0001] The invention belongs to the field of automobile air conditioning, in particular to a vehicle air conditioning system with waste heat recovery function. Background technique [0002] Vehicle air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the vehicle compartment. It can provide a comfortable riding environment for the passengers, reduce the driver's fatigue intensity and improve driving safety. [0003] There are 4 types of vehicle air conditioning systems as follows: [0004] 1. According to the driving mode, it is divided into: independent type (a dedicated engine drives the compressor, large cooling capacity, stable operation, but high cost, large volume and weight, mostly used in large and medium-sized buses) and non-independent type. [0005] 2. According to the performance of the air conditioner, it can be divided into: single-function type and integrated cooling and heating typ...
