Power-adjustable vehicle air conditioner refrigeration and heating selecting circuit

Abstract

The invention discloses a power-adjustable vehicle air conditioner refrigeration and heating selecting circuit; through combined control of an air conditioner mode selecting circuit and a zero-point deviation eliminating circuit, a vehicle air conditioner carries out a refrigeration or heating mode; on the one hand, a motor of an air port deflection motor driving circuit is controlled to deflect to conduct a corresponding air port; and on the other hand, a heating resistance wire driving circuit or a compressor driving circuit is controlled to start to convey hot air or cold air into a vehicle. The vehicle air conditioner is operated in the refrigeration or heating mode, so that the vehicle power consumption is reduced, both energy conservation and emission reduction are achieved, and theendurance time can be prolonged under extreme conditions; through the position change of a knob, the vehicle air conditioner outputs multistage refrigeration or multistage heating; and the mixing problem during selection of the two modes is solved through combination with the actual use process, so that the compressor or heating resistance wire damage caused by frequent compressor or heating resistance wire startup is prevented.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a power-adjustable cooling and heating selection circuit for automobile air conditioners. Background technique [0002] In the prior art, in order to achieve a better experience effect, when the air conditioner is cooling, a large amount of cold air generated by the compressor is mixed with a small amount of hot air generated by the heating resistance wire at the air outlet. When the air conditioner is heating, the heating resistance wire generates A small amount of hot air is mixed with the cold air generated by the compressor at the air outlet, so that the wind blown by the car air conditioner can make people feel more comfortable and increase the experience effect; but no matter when the car air conditioner is cooling or heating, the compressor and the heating resistance wire It is in a working state, which increases the power consumption of the vehicle and...

[0002] In the prior art, in order to achieve a better experience effect, when the air conditioner is cooling, a large amount of cold air generated by the compressor is mixed with a small amount of hot air generated by the heating resistance wire at the air outlet. When the air conditioner is heating, the heating resistance wire generates A small amount of hot air is mixed with the cold air generated by the compressor at the air outlet, so that the wind blown by the car air conditioner can make people feel more comfortable and increase the experience effect; but no matter when the car air conditioner is cooling or heating, the compressor and the heating resistance wire It is in the working state, which increases the power consumption of the vehicle and increases energy consumption

However, for the needs of different models and different customers, it is obvious that the existing technical solutions are too wasteful, or under extreme conditions, when it is necessary to activate the energy-saving mode to extend the battery life, the existing technical solutions cannot meet people's needs. It is necessary to propose a more energy-saving technical solution
