Air conditioner control method

Abstract

The invention discloses an air conditioner control method. The method comprises the steps that 1, the outdoor environment temperature T1 and the temperature T2 of an electrically controlled radiator are detected, the dew-point temperature Td of the outdoor environment is obtained by means of the outdoor environment temperature T1 and relative humidity RH, and comparison is conducted on the dew-point temperature Td and the temperature T2; 2, when T2-Td<delta T1, under the refrigeration working condition, the opening of a first throttling element is increased, and the opening of a second throttling element is decreased; under the heating condition, the opening of the first throttling element is decreased, and the opening of the second throttling element is increased; when delta T2>=T2-Td>=delta T1, the opening of the first throttling element and the opening of the second throttling element are not changed; when T2-Td>delta T2, under the refrigeration working condition, the opening of the first throttling element is decreased, and the opening of the second throttling element is increased; under the heating condition, the opening of the first throttling element is increased, and the opening of the second throttling element is decreased. By means of the air conditioner control method, it can be guaranteed that electronic controlled components are used safely, and the service life of an air conditioner is prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner. Background technique [0002] The heat dissipation method of the electronic control element of the air conditioner outdoor unit of the existing inverter air conditioner is to use a metal radiator to dissipate heat through air convection. The operating frequency of the compressor will be reduced to reduce the heat generation of the electronic control element to ensure the normal operation of the air conditioner, which directly affects the cooling effect of the air conditioner and affects the comfort of the user using the air conditioner. However, when a refrigerant is used to cool down the electronic control element, condensed water is easily generated on the electronic control element due to the low temperature during the heat absorption of the refrigerant, which makes the use of the electronic control element a potential safety ha...

Problems solved by technology

[0002] The heat dissipation method of the electronic control components of the air-conditioning outdoor unit of the existing frequency conversion air conditioner is to use the metal radiator to dissipate heat through air convection. It will reduce the operating frequency of the compressor to reduce the calorific value of the electronic control components to ensure the normal operation of the air conditioner, which directly affects the cooling effect of the air conditioner and affects the comfort of the user when using the air conditioner

However, when the refrigerant is used to cool down the electronic control components, due to the low temperature of the refrigerant in the process of absorbing heat, it is easy to generate condensed water on the electronic control components, which makes the use of the electronic control components a potential safety hazard and affects the service life of the air conditioner
