Control system and method for automatically adjusting refrigerant of air-cooled compression condensing unit

Abstract

The invention belongs to the technical field of air conditioner control, and discloses a control system and method for automatically adjusting a refrigerant of an air-cooled compression condensing unit. According to the control method, a refrigerant pipe is additionally arranged on a system pipe on an air suction pipe or a large valve connecting pipe of an air-conditioning system, an electromagnetic valve is used for stopping the middle of an additionally-arranged fluorine adding pipe, and a fluorine injection nozzle is additionally arranged at the end of the fluorine adding pipe and installedon an air-conditioning outdoor unit; an electromagnetic valve is opened for starting a refrigerant filling mode, and the refrigerant is filled from the fluorine filling nozzle; liquid outlet temperature and pressure detection is added to a condensation outlet pipe of the air conditioning system and used for controlling and detecting the supercooling degree of the refrigerant amount of the system.According to the control system and method, the perfusion amount and the use performance capability of a unit system can be kept consistent in a user installation site and a site test, the system operation reliability is not influenced by human factors, the popularization and application range is wide, and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to a control system and method for automatically adjusting refrigerant of an air-cooled compression condensing unit. Background technique [0002] At present, the closest prior art: air conditioner cooling and cooling, the appearance of the air conditioner is all similar, but its control panel arrangement form and the method adopted are not the same, and the function setting is more or less. You should be familiar with the various functions and uses of the air conditioner in order to correctly grasp the methods of starting and stopping the air conditioner. [0003] Traditional air conditioners are mainly composed of compressors, liquid receivers, air-cooled condensers, dry filters, etc. This unit and some components provided by the project are connected through pipelines and electrical controls to form a complete refrigeration system. The outdoor unit ha...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: the outdoor unit of the traditional air conditioner has already been filled with part of the refrigerant in the factory, and it is necessary to add refrigerant to the entire system during the factory test and user installation, while the actual installation test in the market requires additional refrigerant The amount of additional additions cannot be unified, thus affecting system capability and reliability
