摘要： A transport refrigeration system having electrical control which controls the temperature in a served space via heating and cooling cycles using hot refrigerant gas from a refrigerant compressor. The refrigeration system has high and low pressure sides. The high pressure side includes a discharge manifold of the compressor, a condenser coil, a refrigerant receiver tank, and an evaporator coil associated with the served space. The low pressure side extends from the evaporator coil to a suction manifold of the compressor. A first controllable refrigerant flow path means is controlled by the electrical control to purge the condenser coil in response to predetermined system parameters, causing refrigerant trapped in the condenser coil to flow to the low pressure side of the system. A second controllable refrigerant flow path is controlled by the electrical control to pressurize the receiver tank in response to predetermined system parameters, forcing refrigerant to flow from the receiver tank to the evaporator coil.

摘要： Provided is an air-conditioning apparatus configured so that a decrease in a refrigeration capacity can be suppressed without increasing the amount of refrigerant with which a refrigerant circuit is filled and that refrigerant can be suitably stored during a pump down operation. The air-conditioning apparatus includes a first on-off valve provided at a pipe between an expansion valve and a use side heat exchanger, a bypass branching from a pipe between the expansion valve and the first on-off valve and connected to a pipe at a suction-side of a compressor, and a refrigerant storage unit configured to store the refrigerant having passed through the bypass. In a pump down operation in which the compressor operates with the first on-off valve being in a closed state, the refrigerant having flowed out from the heat source side heat exchanger flows into the bypass, and then, is stored in the refrigerant storage unit.

摘要： A system for starting a refrigeration system includes a liquid line regulating valve, a liquid line charging valve, a suction line expansion valve, a suction line charging valve, and a controller. The controller is configured to override normal operation of the refrigeration system and transmit a demand signal to enable partial system operation. The controller is configured to operate the liquid line regulating valve and the liquid line charging valve to charge a receiver tank, gradually increase the demand signal to a predetermined level of partial system operation, and release the liquid line charging valve to normal operation. The controller is configured to operate the suction line expansion valve and the suction line charging valve to charge a suction line, gradually increase the demand signal to full system operation, and release the liquid line regulating valve, the suction line expansion valve, and the suction line charging valve to normal operation.
