    摘要: A flash tank for a heat pump operable in a heating mode and a cooling mode includes a shell having a middle portion disposed between a top portion and a bottom portion, with the top portion, bottom portion, and middle portion cooperating to define an inner volume of the shell. A first port is in fluid communication with the inner volume and functions as an inlet in the heating mode and as an outlet in the cooling mode. A second port is in fluid communication with the inner volume and functions as an inlet in the cooling mode and as an outlet in the heating mode. Flow control devices and check valves are fluidly coupled to control the tank as a flash tank in heating mode and as a receiver in cooling mode.

    摘要: A method includes operating a compressor with a vapor injection system and selectively supplying vapor to the compressor during compressor operation through actuation of a first control valve. The method further includes closing the first control valve to prevent vapor from entering the compressor for a first predetermined time period leading up to stopping operation of the compressor and stopping the compressor with the first control valve in the closed position. The compressor is started with the first control valve in the closed position and the first control valve is maintained in the closed position for a second predetermined time period following starting of the compressor. The first control valve is opened to supply vapor to the compressor after the second predetermined time period.

    摘要: A heat pump operable in a heating mode and in a cooling mode includes a first heat exchanger and a second heat exchanger. A compressor is in fluid communication with each of the first and second heat exchangers and includes a vapor injection port. A third heat exchanger is in fluid communication with each of the first and second heat exchangers and the compressor and includes a liquid side having an inlet and an outlet and a vapor side having an inlet and an outlet. A vapor injection line fluidly couples the vapor injection port and the outlet of the vapor side. An expansion device is in fluid communication with the inlet of the vapor side to control a volume of liquid entering the vapor side and to expand the liquid prior to entering the vapor side.

    摘要: A method includes operating a compressor of a heat pump system and is selectively providing vapor to a vapor injection port of the compressor via a vapor injection line and vapor injection valve. The method further includes determining a frost condition of a first and second heat exchanger of the heat pump system and closing a vapor injection valve to prevent fluid flow into the compressor at the vapor injection port. A direction of refrigerant flow is reversed to direct vaporized refrigerant to the one of said first and second heat exchangers experiencing the frost condition. The vapor injection valve is opened after a first predetermined time period following reversal of the refrigerant flow. The method further includes closing the vapor injection valve and reversing a direction of refrigerant flow within the heat pump system once the vapor injection valve is closed for a second predetermined time period.

    摘要: A vapor-compression circuit may be used to meet the temperature/load demands for conditioning one or more spaces. Excess heat generated in the vapor-compression circuit may be utilized to generate an electric current that may power other components of the vapor-compression circuit. A thermoelectric device may be placed in heat-transferring contact with the excess heat and generate the electrical current. The electric current generated may be used to power another thermoelectric device to provide further cooling or heating of a fluid in heat-transferring relation therewith to supplement the vapor-compression circuit and the conditioning of the space.
