Abstract

The invention discloses a control system, method and device for the exhaust temperature of a compressor. The control system comprises a temperature sensor, a controller and an electronic expansion valve, wherein the temperature sensor is arranged on an exhaust channel of an exhaust outlet of the compressor and used for collecting the current exhaust temperature of the compressor; the controller is connected with the temperature sensor and used for determining an adjusting parameter of the target opening degree of the electronic expansion valve on the basis of the current exhaust temperature and generating a control signal where the adjusting parameter is recorded; and the electronic expansion valve is connected with the controller, installed on a liquid spraying channel of the compressor and used for adjusting the opening degree to the target opening degree according to the adjusting parameter under triggering of the control signal. By means of the control system, method and device for the exhaust temperature of the compressor, the technical problem that in the prior art, precision for adjusting the exhaust temperature of the compressor is low is solved.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to a control system, method and device for compressor discharge temperature. Background technique [0002] When the compressor in the refrigeration system of the air conditioner is used in the limit range of conditions (such as high condensing temperature or low evaporation temperature), the discharge temperature of the compressor will increase, which will reduce the viscosity of the lubricating oil. In severe cases, the lubricating oil will The lubrication function of the compressor fails, thus restricting the operating range of the compressor. [0003] The means to solve the problem of high exhaust gas temperature in the prior art is mainly liquid spray cooling. Commonly used liquid spray cooling methods include direct liquid spray cooling through nozzles and thermal expansion valve controlled liquid spray cooling. [0004] The nozzle direct liquid spray cooling method refe...
