Abstract

The invention belongs to the technical field of air conditioning and discloses an air conditioning system with adjustable refrigerant quantity. The air conditioning system with the adjustable refrigerant quantity comprises a refrigerant storage unit communicating with a refrigerant circulating pipeline of the air conditioning system; and the refrigerant storage unit is used for adding refrigerant into the refrigerant circulating pipeline or recycling part of refrigerant in the refrigerant circulating pipeline to remain stability of the refrigeration effect or the heating effect of the air conditioning system in the operating process of the air conditioning system. According to the air conditioning system with the adjustable refrigerant quantity, the refrigerant storage unit communicates with the refrigerant circulating pipeline of an original air conditioning system, so that the total refrigerant quantity in the refrigerant circulating pipeline can be adjusted at any time, and the refrigeration effect or the heating effect of the air conditioning system remains stable; a refrigerant storage pot communicates with the refrigerant circulating pipeline through two branches and conducts operation of refrigerant supplementing and refrigerant recycling through the character in the process of refrigerant flowing, and no extra driving unit needs to be arranged; and a capillary pipe can play a role in buffering, reduces the impact effect of high-pressure refrigerant on the refrigerant storage pot and relative pipelines, and protects the pipeline.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system with adjustable amount of refrigerant. Background technique [0002] For multi-connected systems or commercial air conditioners, the replacement of old and new refrigerants has become a trend; 5 to 10 years ago, the air conditioning system mainly used R22 (CHClF2, difluorochloromethane, alias Freon-22) refrigerant, and the current air conditioning system Use R410a (composed of 50% difluoromethane and 50% pentafluoroethane, which is a new type of environmentally friendly refrigerant) or other refrigerants. However, in the system replacement engineering operation, it is often easy to lose the original system piping drawings, resulting in incorrect calculation of the length of the piping, and often unable to determine the total amount of refrigerant required by the air conditioning system when adding new refrigerant.
