Air conditioner heat dissipation structure control method and system

A method for controlling a heat dissipation structure of an air conditioner wherein:

• the heat dissipation structure comprising:
• a refrigerant heat dissipation pipe with an inlet end connected to a liquid pipe between an outdoor heat exchanger and an indoor heat exchanger and an outlet end connected to an inlet pipe of the gas-liquid separator, which is fixed with a heat generating component;
• and
• an electronic expansion valve connected in series to the refrigerant heat dissipation pipe;
• the method comprises:
• obtaining a real-time temperature Te of the heat generating component;
• determining whether the real-time temperature Te>a preset optimal temperature Ted;
• in responsive to Te>Ted, adjusting the electronic expansion valve to a preset initial opening degree;
• obtaining an update real-time temperature Te of the heat generating component after a preset time period;
• determining whether or not the update real-time temperature Te>a preset upper limit value Tmax;
• wherein Tmax>Teed;
• in responsive to the update real-time temperature Te>Tmax performing following steps every set period of time:
• (1) obtaining a refrigerant temperature refrigerant temperature Tin at the inlet end of the refrigerant heat dissipation pipe and a refrigerant temperature Tout at the outlet end of the refrigerant heat dissipation pipe;
• (2) calculating a real-time temperature difference ΔTreal-time of the inlet end temperature Tin and the outlet end temperature Tout, wherein ΔTreal-time=Tout-Tin;
• (3) obtaining a preset target temperature difference ΔTtarget and calculating a deviation ΔTdeviation, ΔTdeviation=ΔTreal-time−ΔTtarget;
• (4) calculating a deviation change rate ΔΔTdeviation=ΔTdeviation−ΔTdeviation′, wherein the ΔTdeviation′ is the deviation calculated last time;
• (5) adjusting the opening degree of the electronic expansion valve based on the deviation ΔTdeviation and the deviation change rate ΔΔTdeviation.
