Title:
AIR CONDITIONER HEAT DISSIPATION STRUCTURE CONTROL METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/149167
Kind Code:
A1
Abstract:
Disclosed in the present invention are an air conditioner heat dissipation structure control method and system, comprising: acquiring the actual temperature Te of an air conditioner heating component, and adjusting an electronic expansion valve to be opened to an initial opening degree when Te is greater than a preset optimum temperature Ted; after setting the time, acquiring the actual temperature Te of the air conditioner heating component again; when the actual temperature Te is greater than a preset upper limit value Tmax, acquiring the refrigerant temperature Tin at the inlet end of a refrigerant heat dissipating pipe and the refrigerant temperature Tout at the outlet end of the refrigerant heat dissipating pipe; calculating the temperature difference ∆Tactual=Tout-Tin; calculating the deviation ∆Tdeviation =∆Tactual-∆Ttarget; calculating the deviation change rate ∆∆ deviation=∆Tdeviation-∆Tdeviation'; and adjusting the opening degree of the electronic expansion valve according to the deviation ∆Tdeviation and the deviation change rate ∆∆Tdeviation, so that the refrigerant temperature difference between the outlet end and the inlet end of the refrigerant heat dissipation pipe reaches a target temperature difference. With the described method, good heat dissipation of the air conditioner heating component is achieved, a relatively good heat dissipation effect is achieved, the cost of heat dissipation is low, and the reliability is high.
