Title:
REAL-TIME HUMIDITY CALCULATION METHOD FOR AIR-CONDITIONED ROOM, AND AIR-CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/057039
Kind Code:
A1
Abstract:
Disclosed is a real-time humidity calculation method for an air-conditioned room, wherein the method comprises: during a working process of an air-conditioner, invoking a compressor operating frequency which is fed back, and according to the compressor operating frequency, a compressor displacement and a refrigerant density, calculating the amount of coolant flowing in a sampling period (S1); collecting a compressor exhaust gas temperature and an outdoor defrosting sensor detection temperature to calculate a first temperature difference (S2); invoking the specific heat of a refrigerant, and calculating the quantity of heat released outdoors by a coolant within a unit of time (S3); invoking an indoor fan wind speed which is fed back, and according to the indoor fan wind speed, calculating an indoor fan blast volume in the sampling period, and calculating an air enthalpy value change in the sampling period (S4); collecting an indoor temperature and an indoor coil pipe temperature to calculate a second temperature difference (S5); and searching an enthalpy-humidity curve graph, and determining a real-time humidity of a current air-conditioned room (S6). By means of the solution, the humidity of an air-conditioned room can be obtained under the condition of no hardware device being added, and the temperature and the humidity are further cooperatively controlled using inferred values, thus having the advantages of being practical and highly precise.
