Abstract
Provided is an air conditioner which has few errors in determining the appropriate amount of refrigerant while maintaining high pressure, ensuring the high and low pressure difference, and suppressing the manufacturing costs. A method for determining the amount of refrigerant in the air conditioner (1) determines the appropriate amount of refrigerant in the refrigerant path in an air conditioner which has a refrigerant path (10) which is capable of at least performing the cooling operation and includes a heat source unit (2) with a compressor (21), a heat source-side heat exchanger (23), and a cooling/heat source adjusting method (27); a utilization unit (4) having a utilization-side heat exchanger (41); an expansion mechanism (33); a liquid refrigerant connection pipe (6); and a gas refrigerant connection pipe (7). Determining the appropriate amount of refrigerant which fills the interior of the refrigerant path is performed based on a first supercooling correction value which corrected and derived the degree of supercooling or the amount for the operating state from at least one of the outdoor temperature, the condensation temperature, and the numerical value of the cooling action as the determination of the appropriate amount of refrigerant.
