Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a refrigerant quantity detection method for a refrigerating system. The method is applied to refrigerating equipment, the refrigerating equipment is provided with a pressure sensor, and when adding of a refrigerant of the refrigerating system is stopped, a compressor of the refrigerating equipment is controlled to operate at a preset frequency; after the compressor operates for a preset duration, a first pressure value collected by a pressure sensor is obtained; and according to the corresponding relation between the pressure values and the refrigerant, the refrigerant amount corresponding to the first pressure value is determined as the current residual refrigerant amount of the refrigerating system. According to the scheme, the refrigerant amount in the refrigerating system can be determined according to the pressure value collected by the refrigerating system after a he maintainer adds the refrigerant, and a more accurate refrigerant amount detection mode is provided for the user, so that the user can determine the residual refrigerant amount information of the refrigerating system, whether the refrigerant amount added by the maintainer is appropriate or not is judged, and the requirements of the user are met. The invention further discloses a refrigerant quantity detection device for the refrigerating system and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a method, device and air conditioner for detecting the amount of refrigerant used in a refrigeration system. Background technique [0002] Refrigerant is a working fluid used in air-conditioning and refrigeration systems to transfer heat energy and produce a freezing effect. During the research and development of air conditioning systems, the amount of refrigerant plays a vital role in whether the system can maximize energy efficiency. During the use of the air conditioner, as the refrigerant volatilizes, the amount of refrigerant in the pipeline gradually decreases. If the amount of refrigerant in the pipeline is insufficient, the stable operation of the refrigeration system cannot be maintained, and maintenance personnel need to be contacted to add refrigerant. In the prior art, maintenance personnel usually determine the amount of refrigerant to be add...
