Air conditioner system and sewage discharge control method thereof

Abstract

The invention provides an air conditioner system and a sewage discharge control method thereof. The air conditioner system comprises a refrigerant pipeline and a filtering device arranged on the refrigerant pipeline; and a first temperature sensing device is arranged on the position, on one side of the filtering device, of the refrigerant pipeline, and a second temperature sensing device is arranged on the position, on the other side of a filter, of the refrigerant pipeline. Through the air conditioner system, the blockage degree of the filter can be judged according to the temperature difference between the front part and the rear part of the filter, and the problems of complex and inconvenient detection process, low accuracy and low efficiency are solved; and through the means that a sewage discharge branch is arranged on one side of the filtering device and control devices are arranged on the refrigerant pipeline and the sewage discharge branch correspondingly, a small number of high-pressure refrigerants in the system can reversely flush a filtering net in the filter by controlling closing of two control valves in front of an expansion valve, thus impurities on the filtering net are stripped and discharged out of the air conditioner system together with the refrigerants, the effect of automatically purifying the air conditioner system is achieved, and the maintenance time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning system and a pollution discharge control method thereof. Background technique [0002] At present, the installation and use of various types of air-conditioning devices from small to large can be seen everywhere. If the air-conditioning devices are not strictly controlled during the production or installation process, foreign matter impurities or copper shavings and welding slag will enter the interior of the air-conditioning system. Therefore, each air-conditioning manufacturer designs In the first stage, filters will be installed at both ends of the throttling device to prevent impurities from entering the throttling device and causing blockage. In the case of less impurities, the filter can indeed play a certain role, so that the operation of the air conditioner will not be affected, but if there are more impurities, it will block the f...
