摘要： A heat pump may include a compressor configured to compress a refrigerant, a first temperature sensor provided in heating pipes connected to a heating device that heats an indoor space to sense a temperature of fluid flowing through the heating pipes, and a controller. The controller may be configured to determine whether a boiler is operating to heat an indoor space or is operating to supply hot water based on a sensing value of the first temperature sensor. The compressor may operate when the controller determines that the boiler is not operating to heat the indoor space and/or determines that the boiler is operating to supply hot water.

摘要： A system for distribution of hydrogen gas in a metal hydride reactor is disclosed. The system comprises a hydrogen distribution conduit positioned within a metal tube so as to define an annular space between the hydrogen distribution conduit and the outer metal tube. The hydrogen distribution conduit provides a flow passage for the hydrogen gas. A metal sponge matrix containing hydrogen-storing metal powder or hydrogen-storing alloy powder is filled in the annular space. The system provides a more uniform distribution of hydrogen across the particles of the hydrogen-storing metal/alloy powder, provides mechanical support to the hydrogen distribution conduit, improves the thermal conductivity of the powdered metal/alloy bed and reduces the size and production cost of the reactor.

摘要： A transcritical R-744 refrigeration system, especially used for refrigerating a skating rink, has a heat exchanger between the gas cooler followed by a throttling device and the flash tank (or receiver), in order to eliminate the need of a flash-gas bypass. The heat exchanger connects to an external mechanical refrigeration system operating at a higher evaporating temperature than the transcritical R-744 refrigeration system, and generally totally condenses the vapor of the R-744 refrigerant before it reaches the flask tank. A method for improving the energy efficiency of the transcritical R-744 refrigeration system is also disclosed.

摘要： A co-fired generator for use in a continuous-cycle absorption heating and cooling system may provide heat to the interior of an annulus chamber from a first heat exchanger, such as a firetube heat exchanger, supplemented by heat to the exterior of the annulus chamber from a second heat exchanger containing fluid heated by an external source. Some embodiments may circulate fluid heated in a solar-heated collector through the second heat exchanger. Other embodiments may route exhaust gas from a combustion engine through the second heat exchanger. The second heat exchanger may be provided with a plurality of fins to increase the surface area available for thermal transfer between the heated fluid and the annulus chamber.

摘要： An evaporator circuit for a second refrigerant used in conjunction with a refrigeration circuit of the type operating a refrigeration cycle. The evaporator circuit has a heat exchange stage having a heat exchanger in a refrigerant accumulator in which the second refrigerant is in heat-exchange relation with the first refrigerant circulating in the heat exchanger in the evaporation stage of the refrigeration circuit. The heat exchanger is positioned in the refrigerant accumulator so as to be immersed in the second refrigerant such that the second refrigerant releases heat to the first refrigerant circulating in the heat exchanger. An evaporator stage has an evaporator in which the second refrigerant absorbs heat from a fluid passing through the evaporator, so as to cool the fluid, whereby the second refrigerant circulates between the heat exchange stage and the evaporator stage.
