Air conditioning system and condensation preventing control method and device for refrigerant radiating pipe of air conditioning system

Abstract

The invention discloses an air conditioning system and a condensation preventing control method and device for a refrigerant radiating pipe of the air conditioning system. The condensation preventingcontrol method comprises the following steps that a current operation mode of the air conditioning system is obtained, and the temperature of the refrigerant radiating pipe and the dew point temperature of air around a frequency conversion module are obtained; the condensation extent of the refrigerant radiating pipe is obtained according to the temperature of the refrigerant radiating pipe and the dew point temperature of the air around the frequency conversion module; and the opening degree of an outdoor throttling element, the opening degree of an indoor throttling element, the air speed ofan outdoor fan and the operation frequency of a compressor are adjusted according to the current operation mode of the air conditioning system and the condensation extent of the refrigerant radiatingpipe so that condensation on the refrigerant radiating pipe can be removed. Through the method, the condensation on the refrigerant radiating pipe can be removed, the situation that condensed water enters an electric control mainboard, and consequently the electric control mainboard is burned out is prevented, and accordingly, the effect that the system operates safely and reliably can be ensured.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an anti-condensation control method for a refrigerant heat dissipation pipe in an air-conditioning system, an anti-condensation control device for a refrigerant heat dissipation pipe in an air-conditioning system, and an air conditioner with the anti-condensation control device system. Background technique [0002] At present, many air-conditioning manufacturers commonly use refrigerant heat dissipation to cool the inverter module in the air conditioner. Compared with the traditional air-cooled cooling method, the temperature of the inverter module can be greatly reduced, so the refrigerant heat dissipation method has become the mainstream technology. [0003] However, when the frequency conversion module is cooled by means of refrigerant heat dissipation, some problems will also occur. For example, when the temperature of the refrigerant cooling pipe is too low,...

Problems solved by technology

[0003] However, when the frequency conversion module is cooled by means of refrigerant heat dissipation, some problems will also occur. For example, when the temperature of the refrigerant cooling pipe is too low, if the temperature of the frequency conversion module is lower than the air dew point temperature, it is easy to cause condensation of the frequency conversion module. Dew, the existence of condensed water will cause the electronic control board of the frequency conversion module to burn
