The heat pump may include a plurality of outdoor units, a plurality of indoor units, and a plurality of flow path switching apparatuses that switch a flow path between an outdoor unit and an indoor unit. A refrigerant flow path may be formed from the outdoor unit to the indoor unit via a high-pressure gas pipe.

摘要： Systems and methods are described herein to use a discharge pressure of a compressor to drive refrigerant in a refrigeration system. Particularly, systems and methods are described herein to help recover liquid refrigerant from a liquid refrigerant section and/or a condenser coil to be used in a heating/defrost mode in a transport refrigerant unit (TRU). The liquid refrigerant can be recovered by directing the discharge refrigerant of the compressor to a liquid refrigerant section, which may include a receiver tank, a dryer and associated refrigerant lines, and/or a condenser coil. The discharge pressure of the discharge port can help drive refrigerant trapped in the liquid refrigerant section and/or the condenser coil into the heating/defrost branch of the TRU, which may include an evaporator coil, an accumulator tank and/or associated refrigerant lines.

摘要： An air conditioning system, which is a refrigeration apparatus that performs a refrigeration cycle in a refrigerant circuit, includes an outdoor heat exchanger, an indoor heat exchanger, a first control valve, a second control valve, a third control valve, and a pressure adjusting portion. The first control valve and the second control valve, which block flow of refrigerant when fully closed, are disposed in a gas-side refrigerant flow path. The gas-side refrigerant flow path is disposed between the outdoor heat exchanger and the indoor heat exchanger. The third control valve, which blocks flow of refrigerant when fully closed, is disposed in a liquid-side refrigerant flow path. The liquid-side refrigerant flow path is disposed between the outdoor heat exchanger and the indoor heat exchanger. The pressure adjusting portion adjusts the pressure of refrigerant in an indoor-side refrigerant flow path. The indoor-side refrigerant flow path is disposed between the first control valve and the second control valve or the third control valve and the indoor heat exchanger. The pressure adjusting portion includes a pressure adjusting valve. The pressure adjusting valve bypasses refrigerant in the indoor-side refrigerant flow path to an outdoor-side refrigerant flow path. The outdoor-side refrigerant flow path is disposed between the first control valve and the second control valve or the third control valve and the outdoor heat exchanger.

摘要： A system includes a heat exchanger coupled to an air conditioning system, and a flash tank is coupled to refrigeration cases, and houses a first refrigerant. The system includes solenoid valves coupled to the flash tank, where the solenoid valves reduce a pressure of the first refrigerant flowing from the flash tank to the heat exchanger. The heat exchanger may be coupled to the solenoid valves, and the heat exchanger may be configured to receive an amount of the first refrigerant from the solenoid valves, receive a second refrigerant from the air conditioning system, where the second refrigerant is associated with an air conditioning load, and provide cooling to the second refrigerant, using the first refrigerant. Finally, the system includes a check valve coupled to the flash tank, where the check valve reduces a pressure of the first refrigerant flowing from the flash tank away from the solenoid valves.

摘要： An apparatus for reducing discharge pressure includes a compensator reservoir and a compensator line. The compensator line connects the compensator reservoir and a liquid line. The liquid line connects an outdoor heat exchanger and an indoor heat exchanger of a reversible HVAC system. The compensator line includes a connection to the compensator reservoir and a connection to the liquid line. A first expansion device is disposed in the liquid line and configured to only act on refrigerant flowing towards the outdoor heat exchanger. A second expansion device disposed in the liquid line and configured to only act on refrigerant flowing towards the indoor heat exchanger. The compensator is operable to receive refrigerant, driven by pressure, from the HVAC system, and further operable to allow refrigerant to flow back into the HVAC system.
