Cooling assembly, air-conditioning system and cooling control method thereof

Abstract

The invention discloses a cooling assembly, an air-conditioning system and a cooling control method thereof. The cooling assembly comprises a coolant heat exchange tube, a first flow control part, a sensor assembly and a master controller, wherein the coolant heat exchange tube is used for inputting coolants to cool an electrical control assembly; the first flow control part is arranged on the coolant heat exchange tube and further used for controlling the flow of coolants flowing through the coolant heat exchange tube; the sensor assembly is used for detecting the environmental dew point temperature and the temperature of the electrical control assembly; and the master controller is connected with the sensor assembly and further regulates and controls the first flow control part accordingto the environmental dew point temperature and electrical control assembly temperature which are detected by the sensor assembly. By means of the cooling assembly, the air-conditioning system and thecooling control method thereof, the problem that a coolant pipe exchanges heat with the electrical control assembly directly through a copper pipe by adoption of coolants, the coolant temperature islow, condensation can happen easily and thus electrical control equipment can be burnt is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat dissipation component, an air conditioning system and a heat dissipation control method thereof. Background technique [0002] At present, in the scheme of dissipating heat for the electric control of the outdoor unit of the air conditioner, a refrigerant pipe is usually used, and the refrigerant in the refrigerant pipe and the electric control are used to exchange heat for heat dissipation. However, if the refrigerant temperature is low, it is easy to cause condensation on the electronic control, which will burn out the electronic control. Contents of the invention [0003] The main purpose of the present invention is to provide a heat dissipation component, an air-conditioning system and a heat dissipation control method thereof, aiming at reducing the risk of condensation in the electric control component. [0004] In order to achieve the above object, the p...
