摘要： Disclosed is an adsorption-based heat pump useful for refrigeration and cooling/heating for applications such as HVACs and chillers. Adsorption is a surface phenomenon where a solid substance (adsorbent) attracts molecules of a gas or solution (refrigerant or adsorbate) on its surface. The latent heat of the adsorbate provides the heating/cooling effect. The novel adsorption heat pump enhances heat and/or mass transfer to and from the adsorbate. One embodiment comprises at least one evaporator, at least one desorber (adsorbent heating apparatus), at least one adsorbent cooling apparatus and at least one condenser. The embodiment employs different techniques to enhance heat and/or mass transfer.

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： A vacuum insulated cabinet structure includes panels having sheet metal outer side walls and polymer inner side walls. The polymer inner side walls are heat-sealed to a layer of polymer material laminated to a flat sheet metal blank to form vacuum cavities. The blank is then bent along fold lines to form a cabinet structure.

摘要： A refrigeration or climate-control system may include a housing, an evaporator, a drain pan, and a fan. The evaporator may be disposed within the housing and may include a coil positioned in a horizontal orientation. The drain pan may be disposed within the housing and may include an inclined lower wall disposed vertically beneath the coil. The lower wall may define an airflow path underneath the coil. The fan may force the air through the housing and airflow path.

摘要： A heat exchanger includes tubes arranged in one direction, and a corrugated fin provided between the tubes. The corrugated fin includes joints joined to the tubes, and fin bodies that connect the joints which are located next to each other along the wave shape. The fin body includes a cut-raised portion that has a shape in which a part of the fin body is cut and raised for promotion of heat transfer. The cut-raised portion includes a cut-raised end on at least one end of the cut-raised portion in the one direction. The cut-raised end has recesses and projections on its surface that increase hydrophilicity of the surface of the cut-raised end.

摘要： An evaporator comprises: a housing with a refrigerant inlet and a refrigerant outlet; heat transfer tubes that are contained in the housing, in which chilled water for heat exchange with refrigerant inside the housing flows; at least one distribution tray that is placed apart from the heat transfer tubes and has a plurality of holes for distributing refrigerant over the underlying heat transfer tubes; a vapor-liquid separator that is placed apart from the bottom of the distribution tray and separates an introduced refrigerant into a vapor refrigerant and a liquid refrigerant; and a pair of support frames that are fixed to either side of the width direction of the housing, wherein the vapor-liquid separator comprises: a chamber that has an inlet port communicating with the refrigerant inlet, a vapor refrigerant exit communicating with the refrigerant outlet, and a plurality of holes formed in the bottom to distribute the liquid refrigerant to the distribution tray; and a plurality of side arms that are formed on either side of the chamber and arranged in the length direction of the chamber and supported by the support frames. Through the present disclosure, it is possible to keep the vapor-liquid separator horizontal and stable and achieve stable heat exchange performance.

摘要： A heat exchanger includes flat tubes, a header, and a refrigerant inlet. The header has a first plate, a second plate, and a third plate. The first plate has a ridge portion defining a tank space. The second plate has a first flow passage and a second flow passage. The first flow passage extends in such a manner that an area of the first flow passage coincides with an area of the tank space. The second flow passage extends in such a manner that an area of the second flow passage does not coincide with the area of the tank space. An upper portion of the first flow passage and an upper portion of the second flow passage are connected to each other via a first connecting flow passage. A lower portion of the first flow passage and a lower portion of the second flow passage are connected to each other via a second connecting flow passage. The third plate has a communicating hole that allows the first flow passage and each of the flat tubes to communicate with each other.

摘要： A refrigeration system includes a main fluid loop and a secondary fluid loop. The main fluid loop includes a compressor and a heat exchanger that circulate a first working fluid. The secondary fluid loop circulates a second working fluid. The secondary fluid loop is in thermal communication with the main fluid loop at the heat exchanger. The secondary fluid loop includes a pump, a thermal energy storage, and a coil fluid line. The secondary fluid loop includes a multi-position valve configured to move between positions that selectively fluidly connect the heat exchanger, the pump, the thermal energy storage, and the coil fluid line.
