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 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 scroll-type machine is disclosed which is particularly well suited for use as a compressor in refrigeration and air conditioning systems and incorporates a unique arrangement for modulating the capacity thereof. In one group of embodiments the capacity of the scroll-type machine is modulated by relative axial movement between the scroll members so as to form a leakage path across the wrap tips and opposed end plates. In another group of embodiments, modulation is achieved by reducing the orbital radius of one of the scroll members to thereby form a leakage path across the flank surfaces of the wraps. In the second group, a plurality of pin members are moveable from a first and second positions. In a first position the plurality of pin members operably enable the scroll members to orbit and in a second position the pin members restrict the orbiting motion of the first scroll members. Both types of scroll separation may be accomplished in a time pulsed manner to thereby enable a full range of modulation with the duration of the loading and unloading periods being selected to maximize the efficiency of the overall system. A motor control arrangement is also disclosed which may be used with either of the modulation methods mentioned above to increase the efficiency of the motor during periods of reduced load. Additionally, either of the modulation arrangements mentioned above may be combined with a delayed suction form of capacity modulation with or without the motor control feature to thereby achieve better operating efficiency under certain conditions.
