摘要： A heat pump system provides at least six modes of heating, cooling, and/or domestic water heating operation, where domestic water heating may occur concurrently with heating or cooling a space in a structure. The heat pump system comprises a desuperheater positioned downstream of the compressor and operable as a desuperheater, a condenser or an evaporator, a source heat exchanger operable as either a condenser or an evaporator, a load heat exchanger operable as either a condenser or an evaporator, a reversing valve positioned downstream of the desuperheater heat exchanger and configured to alternately direct refrigerant flow from the desuperheater heat exchanger to one of the load heat exchanger and the source heat exchanger and to alternately return refrigerant flow from the other of the load heat exchanger and the source heat exchanger to the compressor, and an expansion valve positioned between the load heat exchanger and the source heat exchanger.

摘要： Methods, systems, and device for cycle enhancement are provided in accordance with various embodiments. Various embodiments generally pertain to refrigeration and heat pumping. Different embodiments may be applied to a variety of heat pump architectures. Some embodiments may integrate with vapor compression heat pumps in industrial, commercial, and/or residential applications. Some embodiments include a method that may include at least: removing a first heat from a vapor compression cycle; utilizing the first removed heat from the vapor compression cycle to drive a thermally driven heat pump; or removing a second heat from the vapor compression cycle utilizing the thermally driven heat pump to reduce a temperature of a refrigerant of the vapor compression cycle below an ambient temperature.

摘要： An apparatus includes a flash tank, a load, a first compressor, a coil, a first pipe, and a second compressor. The flash tank stores a refrigerant. The load uses the refrigerant from the flash tank to cool a space proximate the load. The first compressor compresses the refrigerant from the load. The coil within the flash tank receives the refrigerant from the first compressor such that the received refrigerant is within the coil. The refrigerant stored within the flash tank cools the refrigerant within the coil. The first pipe is within the flash tank. The first pipe directs the refrigerant from within the coil out of the flash tank. The second compressor compresses the refrigerant directed out of the flash tank.
