摘要： A thermal management system includes a closed dynamic cooling circuit, and a closed first steady-state cooling circuit. Each circuit has its own compressor, heat rejection exchanger, and expansion device. A thermal energy storage (TES) system is configured to receive a dynamic load and thermally couple the dynamic cooling circuit and the first steady-state cooling circuit. The dynamic cooling circuit is configured to cool the TES to fully absorb thermal energy received by the TES when a dynamic thermal load is ON, and the steady-state cooling circuit is configured to cool the TES when the dynamic thermal load is OFF.

摘要： A method of determining charge loss of a refrigeration system includes the steps of inputting an ambient temperature, a box temperature, and a compressor speed into an electronic controller of the refrigeration system, and calculating a first air side temperature difference across an evaporator by applying an algorithm having a first T-Map representative of normal operating conditions. The controller may then confirm a detection prerequisite is satisfied. Upon confirmation, the controller calculates a second air side temperature difference across the evaporator by applying the algorithm having a second T-Map representative of a loss of refrigerant charge. An action may then be taken from the controller if the first air side temperature difference is less than the second air side temperature difference.

摘要： In order to achieve a reduction in energy consumption in a cooling water supply device without using a database, an equipment control device (70a) of a cooling water supply device: uses the load of a chiller, and a cooling water outlet temperature lower limit setpoint determined in accordance with the set temperature for the cooling water outlet of the chiller, to set a cooling water inlet temperature lower limit setpoint; sets, as the cooling water inlet temperature setpoint, the higher of the lower limit setpoint and the cooling water inlet temperature lower limit value as determined from the outside wet-bulb temperature; and generates a control command for a cooling tower fan and a control command for the cooling water flow volume, so as to match the cooling water inlet temperature and the cooling water outlet temperature respectively with the cooling water inlet temperature setpoint and the cooling water outlet temperature lower limit setpoint which have been set.

摘要： There is disclosed a vehicle air-conditioning device in which a heating qualification by gas injection can sufficiently be obtained. The vehicle air-conditioning device comprises a compressor 2 which compresses a refrigerant, an air flow passage 3 through which air to be supplied into a vehicle interior flows, a radiator 4 disposed in the air flow passage to let the refrigerant radiate heat, a heat absorber 9 disposed in the air flow passage to let the refrigerant absorb heat, an outdoor heat exchanger 7 disposed outside the vehicle interior to let the refrigerant radiate or absorb heat, and a controller. The controller executes a heating mode in which the refrigerant discharged from the compressor 2 radiates heat in the radiator 4 and the refrigerant by which heat has been radiated is decompressed and then absorbs heat in the outdoor heat exchanger 7. The vehicle air-conditioning device comprises an injection circuit 40 which distributes a part of the refrigerant flowing out from the radiator 4 to return the refrigerant to the middle of compression by the compressor 2, and the injection circuit 40 has an expansion valve 30, and a discharge side heat exchanger 35 which performs heat exchange between the refrigerant decompressed by the expansion valve 30 and the refrigerant discharged from the compressor 2 before flowing into the radiator 4.

摘要： This invention relates to the use of chloro-trifluoropropenes as refrigerants in negative-pressure liquid chillers and methods of replacing an existing refrigerant in a chiller with chloro-trifluoropropenes. The chloro-trifluoropropenes, particularly 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpectedly high capacity in liquid chiller applications and are useful as more environmentally sustainable refrigerants for such applications, including the replacement of R-123 and R-11.

摘要： A two-stage pressurizing refrigeration cycle is provided with a suction-side guiding portion in a part of a low-stage side suction pipe that leads from a bypass branch portion, at which a bypass pipe is branched, to a refrigerant suction side of a low-stage side compressor. The suction-side guiding portion guides a lubricating oil from the refrigerant suction side of the low-stage side compressor to a side of the bypass branch portion. The suction-side guiding portion is located at a position in a vertical direction that is equal to or higher than a position in the vertical direction of the bypass branch portion, and a part of the suction-side guiding portion on the refrigerant suction side of the low-stage side compressor is located at a higher position in the vertical direction than a part of the suction-side guiding portion on the side of the bypass branch portion.
