Problems solved by technology
[0002] The defrosting control logic of the heat exchanger in the existing air conditioning system mainly includes the following categories: 1. Timed defrosting. The temperature is used to control the defrosting, but the temperature cannot fully reflect the environmental mechanism of frosting, and the defrosting judgment is not accurate. Complicated control logic implementation, this method is more accurate in defrosting action, but the configuration of multiple sensors and linkage control have relatively high requirements for the design of the unit controller, and will also increase the cost

The invention provides an air conditioning system and an air conditioning system control method. The air conditioning system includes a shell, a heat exchanger, a first illumination sensor and a signal processing module. The heat exchanger is fixed to the shell and is provided with a plurality of channels communicating with the inside and the outside of the shell, the first illumination sensor isarranged in the shell, and the first illumination sensor detects the intensity of light inside the shell; the signal processing module is electrically connected to the first illumination sensor, and the signal processing module receives the intensity of the light inside the shell and compares the intensity of the light inside the shell with a first preset threshold, or the signal processing moduledetermines the light intensity attenuation value according to the intensity of the light inside the shell and the intensity of the light outside the shell; and the signal processing module compares the light intensity attenuation value with a second preset threshold, and the signal processing module judges whether foreign matter exists in the channels of the heat exchanger or not according to thecomparison result. According to the air conditioning system and the air conditioning system control method, the intensity of the light inside the shell is detected, the light intensity attenuation value of the light passing through the heat exchanger is determined, and whether foreign matter such as frost and dirt in the channels exist or not is accurately determined.
Description
technical field [0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning system and a control method for the air conditioning system. Background technique [0002] The defrosting control logic of the heat exchanger in the existing air conditioning system mainly includes the following categories: 1. Timed defrosting. The defrosting is controlled by temperature, but the temperature cannot fully reflect the environmental mechanism of frosting, and the judgment of defrosting is not accurate. Complex control logic is implemented. This method is more accurate in defrosting action, but the configuration and linkage control of multiple sensors have relatively high requirements for the design of the unit controller, and it will also increase the cost. Contents of the invention [0003] The present application provides an air-conditioning system with accurate defrosting and low energy consumption and a control metho...
