An energy-saving control method for air conditioners in cooling mode based on user comfort

Abstract

The invention provides a user comfort-based energy-saving control method in a refrigerating mode of an air conditioner. Through monitoring of indoor and outdoor temperature and based on the temperature difference between indoor temperature and set temperature of an energy-saving control mode, the method can control the operation frequency of an inverter compressor, the opening degree of an electronic expansion valve and the wind speed of indoor and outdoor fans more accurately, so that the operation power of a whole air conditioner can be reduced as much as possible on the premise that the user comfort is guaranteed.

Description

technical field [0001] The invention relates to the technical field of energy-saving control of an air conditioner, in particular to an energy-saving control method of an air conditioner in a cooling mode based on user comfort. Background technique [0002] At present, air conditioners have been widely used in various indoor environments where people work and live. However, the large power consumption of air conditioners has always been a key issue of concern, and it is also a key research field for those skilled in the art. For this reason, an inverter air conditioner has been developed. When the inverter air conditioner is first used, the air conditioner is heated or cooled at the maximum power and maximum air volume, and quickly approaches the set temperature, and then through the stepless speed change of the inverter air conditioner host , automatically provide the required cooling (heating) capacity according to the room conditions, when the indoor temperature reaches ...

However, the large power consumption of air conditioners has always been a key issue of concern, and it is also a key research field for those skilled in the art.

For this reason, an inverter air conditioner has been developed. When the inverter air conditioner is first used, the air conditioner is heated or cooled at the maximum power and maximum air volume, and quickly approaches the set temperature, and then through the stepless speed change of the inverter air conditioner host , automatically provide the required cooling (heating) capacity according to the room conditions, when the indoor temperature reaches the desired value, the air conditioner will run at a constant speed that can accurately maintain this temperature, that is to say, the existing inverter air conditioner simply operates at the maximum Although the goal of reducing power consumption by a large margin is avoided, the compressor speed of the traditional fixed-frequency air conditioner is basically unchanged, and the indoor temperature is easily adjusted by relying on the compressor to "start and stop" continuously. Hot and cold, consumes a lot of power, but does not consider the user's comfort, needs to be improved
