Air conditioner heat dissipation structure control method and system

Abstract

The invention discloses an air conditioner heat dissipation structure control method and system. The actual temperature Te of an air conditioner heating component is acquired, and when the Te is larger than the preset optimum temperature Ted, an electronic expansion valve is adjusted to be opened to an initial opening degree; after set time, the actual temperature Te of the air conditioner heatingcomponent is acquired again; when the actual temperature Te is larger than the preset upper limit value Tmax, the refrigerant temperature Tin at the inlet end and the refrigerant temperature Tout atthe outlet end of a refrigerant heat dissipating pipe are acquired; the temperature difference delta T actuality=Tout-Tin is calculated; the deviation delta T deviation =delta T actuality-delta T target is calculated; the deviation change rate delta delta T deviation=delta T deviation-delta T deviation' is calculated; and the opening degree of the electronic expansion valve is adjusted according to the deviation delta T deviation and the deviation change rate delta delta T deviation, so that the refrigerant temperature difference of the outlet end and the inlet end of the refrigerant heat dissipation pipe reaches the target temperature difference, good heat dissipation of the air conditioner heating component is achieved, a relatively good heat dissipation effect is achieved, the heat dissipation cost is low, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method and system for controlling the cooling structure of an air conditioner. Background technique [0002] At present, inverter air conditioners are widely used in the market due to their advantages of intelligence, high efficiency and energy saving, low noise, and fast temperature adjustment. Inverter air conditioner is a control system that controls and adjusts the speed of the compressor through the frequency converter, so that it is always in the best speed state. However, the frequency converter and some other power components in the electric The heat of the components cannot be dissipated in time. First, the temperature of the inverter exceeds the range, which directly affects the control of the operating frequency of the compressor. In severe cases, the compressor will stop working; The operating temperature range of the device will cause damage t...
