Problems solved by technology

[0003] In order to make the upgrading of the air conditioning circulation system more efficient, more economical, and more environmentally friendly, when updating the air conditioning circulation system, the original air conditioning refrigerant piping is retained and only the indoor and outdoor units of the air conditioner are replaced to achieve the air conditioning cycle. For the replacement of the system, when the updated air-conditioning cycle system needs to be filled with refrigerant, the existing technology is to control the amount of refrigerant filling based on the calculation of the length and diameter of the refrigerant pipe, because in the air-conditioning cycle system The original refrigerant piping was retained during the update. Due to issues such as the age of the original refrigerant piping, the recorded size information may have been lost. Therefore, if the size information of the refrigerant piping in the air-conditioning circulation system cannot be known, it is impossible to cool the air conditioner. reasonable amount of filling

Abstract

The invention provides an air conditioner circulating system, a refrigerant filling control method and an air conditioner and relates to the technical field of air conditioners. The control method is used for reasonably filling the air conditioner circulating system with a refrigerant. The air conditioner circulating system comprises a compressor, a four-way reversing valve, an outdoor heat exchanging loop, an indoor unit, a refrigerant storing device, an electromagnetic valve, a first electronic expansion valve, a subcooler and a gas-liquid separator. The embodiment of the invention is used for manufacturing the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner cycle system, a method for controlling refrigerant filling and an air conditioner. Background technique [0002] Multi-connected air conditioners have been used in large and medium-sized buildings such as buildings and shops many years ago. With the passage of time, the cooling and heating capacity of the original multi-connected air conditioners has continued to decline, and energy consumption has gradually increased. Changes in the office environment, spatial layout and environmental heat load have all changed, and people have put forward new adjustment requirements for air conditioners, so it is necessary to renovate and update the old multi-connected air conditioning circulation system in the building. [0003] In order to make the upgrading of the air conditioning circulation system more efficient, more economical, and more environmentally friendl...
