    摘要: A combined air-conditioning and hot water supply system includes a refrigeration cycle mechanism, a hot water storage tank, and a controller. The refrigeration cycle mechanism has a compressor whose operating frequency can be controlled, a plate water-heat exchanger that heats water, a hot water supply pressure-reducing mechanism, and an outdoor heat exchanger. The controller includes a clock section, a computing section, a memory section, and a controlling section. The clock section measures time. The computing section calculates the actual hot water supply load. The memory section stores information related to the hot water supply load calculated by the computing section. The controlling section controls the operating frequency of the compressor based on the quantity of heat storage, the hot water supply load, and a preset hot water supply time.

    摘要: A vehicular heat pump system may have two inside heat exchangers within an HVAC module, and may operate in mild cooling and mild heating modes. In mild cooling mode, a first isolation valve and a second isolation valve are fully open and closed, respectively, to direct the refrigerant flow to the first inside heat exchanger only. In mild heating mode, the first isolation valve and the second isolation valve are fully closed and fully open, respectively, to direct the refrigerant flow to the second inside heat exchanger only. In both modes, a first metering device is partially open to control the flow and expansion of the refrigerant, and a second metering device is fully closed to prevent the refrigerant from flowing between the inside heat exchangers. This staged operation of the heat pump system may reduce the risk of flash fog as well as reduce discharge air temperature spreads.

    摘要: Disclosed are embodiments of heat pump systems and methods for operating such systems in the heating mode while a heat pump operating parameter reaches or is equal to a predetermined operating value at which it is not advisable to use conventional heat pump systems for heating an enclosed structure. In addition to ancillary components, the heat pump systems includes indoor, outdoor and auxiliary heat exchangers, reversing and flow diverting valves, compressors, refrigerant superheat controllers, and auxiliary energy sources. During the heating mode of operation, while the heat pump operating parameter reaches or is equal to the predetermined operating value, the flow of liquid refrigerant through the outdoor heat exchangers is inhibited and is diverted to flow through the auxiliary heat exchangers. Thermal energy from the auxiliary energy source is used for evaporating the liquid refrigerant flowing through the auxiliary heat exchangers.
