摘要： A refrigerant charging method in an air conditioner (1) that uses carbon dioxide as a refrigerant includes a first refrigerant charging step and a second refrigerant charging step. The first refrigerant charging step is a step of charging a refrigerant charging target portion including refrigerant communication pipes (6, 7) with refrigerant in a gas state until the pressure of the refrigerant charging target portion rises to a predetermined pressure after the start of charging. The second refrigerant charging step is a step of charging the refrigerant charging target portion with refrigerant in a liquid state until the amount of refrigerant charging the refrigerant charging target portion becomes a predetermined amount after the first refrigerant charging step.

The refrigerant circuit allows a high-temperature side refrigerant to circulate therethrough. The high-temperature side refrigerant has a carbon-carbon double bond in its molecular structure. The high-temperature side compressor 11 has a variable discharge capacity and is configured to discharge the high-temperature side refrigerant. The low-temperature side circulation circuit 20 forms a refrigerant circuit in which a low-temperature side compressor 21, a low-temperature side condenser 22, a low-temperature side expansion device 23, and a low-temperature side evaporator 24 are connected by a pipe. The refrigerant circuit allows a low-temperature side refrigerant to circulate therethrough. The low-temperature side refrigerant contains carbon dioxide. The low-temperature side compressor 21 is configured to discharge the low-temperature side refrigerant. The cascade capacitor 30 is formed of the high-temperature side evaporator 14 and the low-temperature side condenser 22 and configured to cause heat exchange between the high-temperature side refrigerant and the low-temperature side refrigerant. The control means 40 is configured to control an evaporating temperature of the high-temperature side refrigerant in the high-temperature side evaporator 14 on the basis of the pressure according to detection by pressure detecting means such that a pressure inside the high-temperature side circulation circuit does not have a negative pressure with respect to a pressure outside the circuit.

摘要： A control system controls the output capacity of a compressor to avoid surge conditions in the compressor. The control system determines a capacity control output for the compressor and then modifies the capacity control output in view of any output limiters or overrides as determined by system operating parameters and to maintain a minimum frequency of operation for the compressor.
