Problems solved by technology

[0002] For the heating function of the inverter air conditioner, since the outdoor heat exchanger is used as an evaporator, it will condense into water on the surface of the fins during operation. When the temperature of the surface of the fins is lower than zero, the water will form frost. Over a long period of time, the entire heat exchanger will be blocked, affecting the heat exchange effect. The performance is that the temperature of the air outlet in the room will drop, which will affect the heating comfort of the user.

Embodiment 1

[0018] This application provides a control method for an inverter air conditioner, which is applied to an inverter air conditioner with an indoor coil, an inverter compressor, and an indoor fan. figure 1 As shown in , the method includes:

[0019] S101. Periodically detect the indoor ambient temperature and the temperature of the indoor coil after the air conditioner has been running for a period of time.

[0020] For example, after the inverter compressor of the air conditioner is turned on for heating and running for a period of time (for example, 10 minutes), the difference between the indoor ambient temperature and the temperature of the indoor coil can be detected as the initial temperature difference ΔT 0 , and record the frequency of the inverter compressor as the initial frequency F 0 ; The difference between the detected indoor ambient temperature and the indoor coil temperature in the nth cycle is the cycle temperature difference ΔT n .

[0021] The cycle can be s...

Abstract

The invention discloses a variable-frequency air conditioner control method and device, and relates to the technical field of air conditioners. The variable-frequency air conditioner control method and device are used for ensuring the effect that the temperature of an indoor air outlet is not lowered. The method is applied to a variable-frequency air conditioner which is provided with an indoor coil pipe, a variable-frequency compressor and an indoor fan. The method is characterized by comprising the steps that after the heating function of the air conditioner is operated for a period of time,the indoor environment temperature and the temperature of the indoor coil pipe are detected periodically; and the frequency of the variable-frequency compressor and the rotating speed of the indoor fan are adjusted according to the change condition of the difference between the indoor environment temperature and the temperature of the indoor coil pipe. The embodiment of the invention is applied to control over the variable-frequency air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for an inverter air conditioner. Background technique [0002] For the heating function of the inverter air conditioner, since the outdoor heat exchanger is used as an evaporator, it will condense into water on the surface of the fins during operation. When the temperature of the surface of the fins is lower than zero, the water will form frost. Over a long period of time, the entire heat exchanger will be blocked, affecting the heat exchange effect. The performance is that the temperature of the air outlet in the room will drop, which affects the heating comfort of the user. Contents of the invention [0003] Embodiments of the present application provide a method and device for controlling an inverter air conditioner, which are used to ensure that the temperature of an indoor air outlet does not drop. [0004] In order to achieve the abov...
