Air conditioning system, control method thereof and vehicle

Abstract

The invention provides an air conditioning system, a control method thereof and an automobile. The air conditioning system comprises a compressor (1), an external heat exchanger (11), an indoor heat exchanger (19), and a refrigerant pipeline connected with the compressor (1), the external heat exchanger (11) and the indoor heat exchanger (19); an engine water circulating system comprises an engine(15) and a first waterway (101) connected with the engine (15), the air conditioning system further comprises a water pipeline (103), and the first waterway (101) and the water pipeline (103) can perform heat exchange; the refrigerant pipeline is further provided with a water heater inner heat exchanger (10) which can perform heat exchange with the water pipeline (103). Accordingly, heat generated by the engine is effectively utilized, residual heat of the engine is recycled, the energy utilization efficiency is improved, the quantity of hot water production is increased, and the user comfortis improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning system, a control method thereof, and an automobile. Background technique [0002] Now the RV air conditioning system generally adopts a single-cooling air-conditioning system + engine cooling water heating scheme. In winter, this system can only use the waste heat of the engine to heat the interior of the car, and the remaining engine waste heat is released to the environment. The water heater system of the RV generally adopts electric heating. +solar heating method or gas heating+solar heating method, the waste heat of the engine cannot be well used to heat hot water in winter, so that part of the waste heat of the engine is released to the environment in vain, resulting in energy waste. The refrigerator system of the RV is generally operated separately, and the refrigerator in summer The heat generated by the condenser will be released ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome that the winter engine waste heat of automobile air conditioners in the prior art can only provide heating for the vehicle interior, and cannot more effectively recycle the remaining engine waste heat, but directly discharges it into the environment, resulting in unnecessary energy consumption. wasteful defects, thereby providing an air-conditioning system and its control method and automobile
