Energy-saving logic design method for electric air conditioner

Abstract

The invention discloses an energy-saving logic design method for an electric air conditioner. The method comprises the steps of designing division logic of use seasons of the electric air conditioner, defining seasonal temperatures, defining compressor rotating speeds in spring and autumn, defining switch point logic of an air outlet of the electric air conditioner in early summer, defining switch point logic of an air outlet of the electric air conditioner in summer, defining compressor rotating speeds in early summer and summer, defining the rotating speed updating logic and defining compressor rotating speed increasing logic in early summer and summer; the seasons are judged according to the external temperature, then the optimal rotating speed of the compressor is judged according to the seasons, the set temperature, the evaporator temperature and the wind speed gear, and the designed energy-saving logic of the electric air conditioner can reduce the rotating speed of the compressor in spring and autumn, so that the energy consumption of the compressor is reduced; and on the premise of meeting the comfort requirement of a human body, the driving endurance mileage of the vehicle can be increased, and a good energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving control of an electric vehicle air conditioner, in particular to an energy-saving logic design method for an electric air conditioner. Background technique [0002] At present, for electric vehicles, battery life is the most concerned thing for consumers, and starting the air conditioner will simultaneously consume battery power, resulting in a decline in the battery life of electric vehicles. It is of great research significance to save power while meeting comfort requirements. At present, electric vehicle electric air-conditioning systems on the market basically do not have external temperature sensors, and cannot judge seasons. The compressor speed value is relatively high, especially in spring and autumn. The energy consumption of the electric air conditioner is relatively high, which directly affects the cruising range; therefore, the present invention proposes an energy-saving logical ...

Problems solved by technology

[0002] At present, for electric vehicles, battery life is the most concerned thing for consumers, and starting the air conditioner will simultaneously consume the power of the battery, resulting in the failure of the electric vehicle As the battery life decreases, how to meet the requirements of human comfort and save electricity in different environments is of great research significance. At present, electric vehicle electric air conditioning systems on the market basically do not have external temperature sensors, so they cannot Judging by the season, the rotational speed of the compressor is relatively high, especially in spring and autumn, the energy consumption of the compressor is relatively high, which directly affects the cruising range; therefore, the present invention proposes an energy-saving logic design method for electric air conditioners to solve the deficiencies in the prior art place
