| 发明名称 | Refrigerating device, in particular for aircraft | ||
| 摘要 | The invention relates to a refrigerating device (10), in particular for an aircraft, having a refrigerant circuit, in which a refrigerant container (12), an expansion valve (14), an evaporator (16), a compressor (20) and a condenser (22) are disposed. To save energy during operation and to increase the reliability and availability of the refrigerating device (10), in the refrigerant circuit there is a compressor bypass line (26), in which a bypass valve (18) is disposed, and a refrigerant pump (30) that is disposed downstream of the condenser (22) and upstream of the evaporator (16). It is possible to dispense with the refrigerant pump (30) if the condenser (22) is disposed at a higher level than the evaporator (16) in the refrigerant circuit. | ||

| 主权项 | 1. Refrigerating device, in particular for an aircraft, having a refrigerant circuit, in which are disposed: a refrigerant container, an expansion valve, an evaporator, a compressor, and a condenser, wherein the refrigerant circuit further comprises a compressor bypass line, in which a bypass valve is disposed, as well as a refrigerant pump that is disposed downstream of the condenser and upstream of the evaporator, wherein the refrigerant pump is disposed downstream of the refrigerant container in the refrigerant circuit, and the refrigerant pump is connected in parallel to the expansion valve wherein the expansion valve closes automatically if the refrigerant pump is in operation when the ambient temperature is below a predetermined ambient temperature. | ||
