Abstract

The invention discloses an air conditioning device which comprises an outdoor unit, at least one indoor unit and a controller. The indoor unit is connected with the outdoor unit; the outdoor unit comprises a compressor and an outdoor heat exchanger; the indoor unit comprises an indoor heat exchanger; the controller is configured with a refrigerant leakage amount detection mode, and when the controller is started, the outdoor unit is controlled to operate in a refrigeration mode; indoor unit superheat degree control, system high-pressure control and evaporation temperature control are executed; the controller is provided with compressor operation set time and is configured to judge whether the operation time of the compressor in the refrigerant leakage amount detection mode reaches the compressor operation set time or not; if yes, the supercooling degree of the outdoor heat exchanger is obtained, and the system refrigerant amount is calculated; the system refrigerant leakage amount is equal to the difference of the system refrigerant amounts of the two adjacent refrigerant leakage amount detection modes. According to the invention, the precision of refrigerant leakage detection is improved, system problems are convenient to check, and the maintenance efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of air conditioning technology, in particular to an air conditioning device. Background [0002] In the operation of the air conditioning system, due to the poor sealing of the system, there is leakage, and the accumulation of time often leads to an abnormal amount of refrigerant in the system. When the amount of refrigerant in the air conditioning system is abnormal, it will affect the cooling and heating effect of the unit, and even affect the operational reliability of the unit when it is serious. Therefore, in the process of using the air conditioning system, it can accurately measure the leakage of the refrigerant, which can provide greater convenience for after-sales personnel to troubleshoot problems and system maintenance, and is also conducive to improving service levels. [0003] At present, the amount of refrigerant leakage in the air conditioning system of some manufacturers in the industry is small, an...
