Refrigerant leak determination apparatus, control device, computer readable medium, and refrigerant leak determination method

(canceled)

A non-transitory computer readable medium storing a refrigerant leak determination program causing a computer to execute:

• an operation control process that causes a refrigeration cycle device to perform oil recovery operation to collect oil inside a refrigerant circuit of the refrigeration cycle device in a compressor, the refrigeration cycle device including the refrigerant circuit in which the compressor, a condenser, an expansion valve, and an evaporator are connected, performing a refrigeration cycle in which a refrigerant circulates through the refrigerant circuit, and including a service port that includes a communication opening to an internal space of the refrigerant circuit, and to which a pressure sensor that measures a refrigerant pressure in the internal space and whose resolution is in a range from 5 kPa inclusive to 10 kPa inclusive, can be connected;
• and
• a determination process to determine a leak of the refrigerant from the refrigerant circuit, by comparing a reference pressure for comparison, with the refrigerant pressure measured by the pressure sensor after the oil recovery operation.

A refrigerant leak determination method comprising:

• connecting a pressure sensor to a service port after oil recovery operation to collect oil inside a refrigerant circuit in a compressor, the oil recovery operation being performed by a refrigeration cycle device including the refrigerant circuit in which the compressor, a condenser, an expansion valve, and an evaporator are connected, performing a refrigeration cycle in which a refrigerant circulates through the refrigerant circuit, and including the service port that includes a communication opening to an internal space of the refrigerant circuit, and to which the pressure sensor that measures a refrigerant pressure in the internal space and whose resolution is in a range from 5 kPa inclusive to 10 kPa inclusive, can be connected;
• and
• determining a leak of the refrigerant from the refrigerant circuit, by comparing a reference pressure for comparison, with the refrigerant pressure measured by the pressure sensor.
