Abstract

The invention discloses a low-temperature efficient heating air conditioning system which comprises an outdoor evaporator, an indoor condenser, an economizer, a regulating valve and a mixing bin, the economizer is provided with a heating inlet, a heating outlet, a cooling inlet and a cooling outlet, and the outdoor evaporator is provided with an inlet, a first outlet and a second outlet. The cooling inlet is connected to an outlet of the indoor condenser, the cooling outlet is connected to the inlet, the heating inlet is connected to the first outlet, the heating outlet is connected to the mixing bin, the second outlet is connected to the mixing bin, and the adjusting valve is arranged between the second outlet and the mixing bin. Heat exchange is carried out through the economizer, waste heat is absorbed, waste heat recovery is achieved, the heating requirement is met, and the endurance mileage cannot be greatly reduced. Adjustment can be achieved through the opening degree of the adjusting valve, so that effective control is achieved, the compressor works under the stable working condition as much as possible, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the field of vehicle-mounted air conditioners, in particular to an air-conditioning system for low-temperature and high-efficiency heating. Background technique [0002] The existing vehicle air-conditioning system generally encounters the problem of unsatisfactory heating effect at low temperature, so PTC is used for auxiliary heating. However, the energy efficiency ratio of PTC auxiliary heating is generally only about 0.9, resulting in a significant reduction in cruising range. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and the present invention provides a low-temperature and high-efficiency heating air-conditioning system. [0004] The present invention is achieved through the following technical solutions: [0005] An air-conditioning system for low-temperature and high-efficiency heating, which includes an outdoor ev...
