Abstract

The invention relates to an air-conditioning system which comprises an indoor machine and an outdoor machine, wherein the outdoor machine comprises a condenser, a condensation fan, a temperature sensor, a pressure sensor and a control panel, wherein the temperature sensor is used for collecting temperature; the pressure sensor is used for collecting condensation pressure; the control panel is used for detecting whether the pressure sensor and/or the temperature sensor malfunction/malfunctions, regulating the rotation speed of the condensation fan according to the condensation pressure collected by the pressure sensor when the pressure sensor does not malfunction, regulating the rotation speed of the condensation fan according to the temperature collected by the temperature sensor when the pressure sensor malfunctions but the temperature sensor does not malfunction, and controlling the rotation speed of the condensation fan according to default parameter values when both the pressure sensor and the temperature sensor malfunction. Through implementing the technical scheme provided by the invention, the control method can be automatically switched when a single control method is invalid, and the normal and efficient operation of the air-conditioning system can be ensured.

Description

technical field [0001] The invention relates to refrigeration technology, more specifically, to an air-conditioning system and a control method for a condensing fan thereof. Background technique [0002] With the rapid development of science and technology and the continuous innovation and improvement of technology, people have higher and higher requirements for the reliable and efficient operation of air conditioning systems. The intelligence of the air conditioning system has become the highlight of technological innovation and is gradually being paid attention to by people. At the same time, with the national call for energy conservation and emission reduction, the air conditioning system has higher and higher requirements for energy conservation. An air conditioning system usually consists of the following parts, including compressor, evaporator, throttling device, condenser and control system. In the refrigeration industry, we will reduce energy consumption and improv...
