Abstract

The invention discloses an energy-saving control method of a vehicle air conditioner. The energy-saving control method includes the steps that when the air conditioner starting is detected, an inner and outer circulation air door of the air conditioner is switched to an inner circulation air door; a humiture value in a vehicle is detected to judge whether the humiture value is less than a first preset value or not, if yes, the inner and outer circulation air door is stepped to the inner circulation air door of the air conditioner by the specified amount, and if no, the inner circulation air door is stepped to an outer circulation air door of the air conditioner by the specified amount. The invention further relates an energy-saving control device of the vehicle air conditioner. According to the energy-saving control method and device of the vehicle air conditioner, on the premise of ensuring the heating effect, inner circulation is used as much as possible, the using ratio of outer circulation is lowered, and then heating power of the air conditioner is lowered and the loss of the electric quantity of a vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving of new energy automobile air conditioners, in particular to an energy saving control method and device of an automobile air conditioner. Background technique [0002] With the country's promotion of new energy vehicles, the number of new energy vehicles is increasing, and the air conditioners of new energy vehicles basically consume the energy of batteries when heating. How to reduce the power consumption of air conditioners for heating? It has always been the focus of exploration and research and development by various new energy OEMs. When car air conditioners are used, they generally use external circulation or internal circulation. External circulation means that fresh air is obtained from outside the car and enters the car. Internal circulation means that the air inside the car is self-circulating, and no fresh air from outside the car enters the car. When the driver and occupants brea...
