Wind speed control method and air conditioner for frequency conversion air conditioner

Abstract

The invention discloses an air speed control method for a variable frequency air conditioner and the air conditioner. The method comprises the steps that the midpoint temperature of a coiled pipe of an evaporator, the indoor environment temperature, the outdoor environment temperature and the running frequency and setting temperature of a compressor are obtained; according to the midpoint temperature of the coiled pipe of the evaporator, the first rotating speed of an indoor fan is calculated; according to the indoor environment temperature, the second rotating speed of the indoor fan is calculated; according to the outdoor environment temperature, the third rotating speed of the indoor fan is calculated; according to the running frequency of the compressor, the fourth rotating speed of the indoor fan is calculated; according to the difference between the setting temperature and the indoor temperature, the fifth rotating speed of the indoor fan is calculated; and according to the first rotating speed, the second rotating speed, the third rotating speed, the fourth rotating speed and the fifth rotating speed of the indoor fan, the execution rotating speed of the indoor fan is determined. According to the air speed control method, the multiple parameters are adopted for controlling the rotating speeds of the indoor fan of the variable frequency air conditioner, and the air speed of the variable frequency air conditioner in the heating mode can be precisely controlled.

Description

technical field [0001] The invention relates to a wind speed control method of a variable frequency air conditioner and an air conditioner, belonging to the technical field of air conditioners. Background technique [0002] Generally speaking, an air conditioner is a device used to cool or heat indoor air. The device discharges heat from the surroundings when the liquid refrigerant vaporizes and releases heat when the refrigerant liquefies by applying a normal refrigeration cycle that circulates refrigerant. Its thermal properties carry out heat exchange with the air (cold air or warm air), thereby regulating the indoor temperature. [0003] Conventional air-conditioning products can only manually set the operating modes of cooling, heating, and dehumidification. At present, the air conditioner is equipped with fans and blades to control the airflow (wind direction and air volume) of the exhausted air. The air volume is controlled by people through the remote control or the ...

AI Technical Summary

Problems solved by technology

Among them, the wind speed of automatic wind control is generally only related to the difference between the current indoor temperature and the set temperature TS, which is relatively simple and does not meet the needs of precise control of air conditioners, nor does it meet the development trend of fine adjustment of air conditioners
