    摘要： A vapor compression system includes an evaporator, a compressor, and a condenser interconnected in a closed-loop system. In one embodiment, a multifunctional valve is configured to receive a liquefied heat transfer fluid from the condenser and a hot vapor from the compressor. A saturated vapor line connects the outlet of the multifunctional valve to the inlet of the evaporator and is sized so as to substantially convert the heat transfer fluid exiting the multifunctional valve into a saturated vapor prior to delivery to the evaporator. The multifunctional valve regulates the flow of heat transfer fluid through the valve by monitoring the temperature of the heat transfer fluid returning to the compressor through a suction line coupling the outlet of the evaporator to the inlet of the compressor. Separate gated passageways within the multifunctional valve permit the refrigeration system to be operated in defrost mode by flowing hot vapor through the saturated vapor line and the evaporator in a forward-flow process thereby reducing the amount of time necessary to defrost the system and improving the overall system performance. In one preferred embodiment of the invention, a heat source is applied to the heat transfer fluid after the heat transfer fluid passes through the expansion valve and before the heat transfer fluid enters the evaporator. The heat source converts the heat transfer fluid from a low quality liquid vapor mixture to a high quality liquid vapor mixture, or a saturated vapor.

    摘要： A method and device is disclosed for removing residual oil and other contaminants from the refrigerant stream flowing to low-temperature stages of a cryogenic refrigerator. A stream of vapor and liquid refrigerant coming from an air-cooled condenser is injected into a cyclone chamber [32] through the inlet tube [34]. While the liquid drains down a conical section [36] and out through a liquid line [38], the vapor phase moves up into a packing of metal platelets [42] which is cooled by a returning stream of cold vapor passing through a tube [48] wrapped around the column. A portion of the vapor condenses on the platelets and is maintained in equilibrium with the vapor. Since high-molecular-weight contaminants are more soluble in the liquid phase, they are carried down the column with the drops of condensate and are swept out with the liquid fraction through the liquid line [38]. Consequently, the vapor sent out vapor line [46] and into the low-temperature stages of the refrigeration system is cleansed of all oil residues and contaminants. A low-temperature refrigeration system with such a device can be operated continuously for many weeks with no signs of clogging. Moreover, the fractionating column is inexpensive, contains no moving parts, and does not add significant volume to the system.

The aggregated channel switching unit including a plurality of first refrigerant pipes having switch valves, a plurality of second refrigerant pipes, and a casing accommodating the first and second pipes. The first and second pipes are aggregated as an assembly. The first pipes are connected to a high-low pressure gas communicating pipe and a suction gas communicating pipe extending from the heat source unit. The second refrigerant pipes are connected to a liquid communicating pipe extending from the heat source unit and a liquid pipe extending to the utilization units. Adjacent pairs of the first and second pipes extend approximately in parallel to each other at predetermined intervals in the assembly. The first and second pipes are alternately disposed in the assembly.

    摘要： A system and method for reducing the refrigerant charge in a refrigeration system by preheating the liquid refrigerant before it is introduced to the evaporator inlet. When refrigerant liquid is introduced to the evaporator inlet, a portion of the refrigerant liquid vaporizes. This refrigerant vapor displaces refrigerant liquid at the inlet of the evaporator. As more refrigerant vapor is introduced, the amount of liquid inside the evaporator is reduced. A heat exchanger is placed before the liquid refrigerant inlet of the evaporator to generate more vapor when the refrigerant enters the evaporator.
