The invention discloses an anti-condensation control method for electronic control on the
refrigerant heat dissipation of an air conditioner. The anti-condensation control method comprises the following steps: an environment temperature T1 and a
refrigerant heat dissipation
pipe temperature T2 are acquired, and the
temperature difference value t between the environment temperature T1 and the
refrigerant heat dissipation
pipe temperature T2 is calculated; if the
temperature difference value t is greater than a first preset temperature, the opening degree of an
electronic expansion valve of an outdoor unit is controlled to be increased in a preset
control manner; and because the opening degree of the
electronic expansion valve of the outdoor unit is increased, interception for a refrigerant is reduced and then the flow rate of the refrigerant is increased, the refrigerant flows through a refrigerant heat dissipation
pipe and then the refrigerant heat dissipation pipe temperature T2 rises, and the
temperature difference value t is reduced in the case of the invariable environment temperature T1, so that an electronic control board is prevented from generating condensation. The invention further discloses an anti-condensation control device for electronic control on the refrigerant heat dissipation of an air conditioner. The method and the device solve the problem that the electronic control board generates
dew to influence the electronic control reliability when the refrigerant heat dissipation pipe temperature is lower than a
dew point temperature during the running of the air conditioner.
