摘要： Heat is recovered from a heat source to heat water to high temperatures. Apparatuses, systems and methods are described to heat water to a high temperature by using heat, such as may be considered in some instances as waste heat, recovered from a heat source. The methods, systems, and apparatuses described utilize low pressure refrigerant(s) as a fluid to provide a refrigeration cycle that utilizes a source of heat to heat water to a high temperature. The refrigeration cycle can be with or without a cascade cycle. The refrigerant cycle in some examples uses an oil free compressor.

摘要： A refrigerant circuit is disclosed. The refrigerant circuit includes a compressor, a condenser, a first expansion device, an economizer, a second expansion device, and an evaporator fluidly connected. A working fluid flows through the refrigerant circuit. A bypass segment is fluidly connected to the refrigerant circuit. A portion of the working fluid is provided from the refrigerant circuit to the bypass segment from a location in the refrigerant circuit disposed between the condenser and the evaporator with respect to flow of the working fluid. The portion of the working fluid flows through the bypass segment in a flow enabled state and is provided to a location in the refrigerant circuit disposed between the economizer and the evaporator with respect to flow of the working fluid. A vortical flow is induced at the location in the refrigerant circuit disposed between the economizer and the evaporator.

摘要： Oleophobic and/or philic surface(s) are utilized for oil separation, direction, and/or collection in a refrigeration system. Surfaces of component(s) of a refrigeration system (compressor, oil separator, evaporator, etc.) are produced to be oleophobic or philic. The oleophobic and/or philic surfaces are utilized to direct a flow path of oil within the refrigeration system or to prevent oil connection in an area. Refrigerant phobic and/or lubricant phobic material(s) also may be utilized to help promote separation of refrigerant vapor from refrigerant liquid and/or from oil in refrigeration systems.

摘要： A refrigerant displacement device is used to reduce subcooler refrigerant charge while enhancing heat transfer performance, e.g. by maintaining and/or increasing subcooler performance. The refrigerant displacement device physically takes up volume of the subcooler that would normally be occupied by refrigerant. The refrigerant displacement device can be a baffle structure with orifices through which the subcooler's heat exchange tubes are allowed to be inserted. Refrigerant is still allowed, however, to flow through the remaining volume of the subcooler and through openings constructed as, e.g. annuluses, between the tube(s) and the refrigerant displacement device, so as to allow refrigerant flow from an inlet of the subcooler to an outlet of the subcooler.

摘要： Generally, management of refrigerant in an evaporator of an HVAC chiller is described. Methods, systems, and apparatuses to manage refrigerant in an evaporator can include one or combination of the following approaches: (1) by use of a refrigerant displacement array to physically prevent refrigerant from residing where the array is positioned (2) by control of the interstitial velocity of refrigerant flow within the volume of the shell of an evaporator; (3) by a phase biased distribution of the refrigerant mixture, so that a gaseous portion is uniformly distributed into the evaporator shell, while liquid refrigerant and oil is distributed into the evaporator shell at a designated area; and (4) by preventing or reducing the occurrence of foaming inside the evaporator through anti-foaming surfaces, such as by the use of refrigerant phobic and lubricant phobic material(s). Refrigerant management can in turn improve the thermal performance and overall efficiency of the evaporator.
