Problems solved by technology

However, efficient heat exchange cannot be achieved by deteriorating the aspect ratio of the available surface to volume
While microchannel coolers are capable of excellent heat transfer due to the increased surface area, there is a significant pressure drop across the system
Such a significant pressure drop is not only detrimental to the reliability of the unit; it also reduces the overall coefficient of performance of the heat pump

Embodiment Construction

[0063] figure 1A schematic diagram of an absorption refrigeration system 9 with a solar power supply is shown. An aqueous solution of ammonia, for example, can be contained in a solvent evaporator 91 designated as an ejector of the absorption refrigeration system. In this case, the solution is heated indirectly by, for example, steam or hot water from a thermal solar system. As an alternative to thermal solar systems, other suitable heat sources that can provide the necessary evaporation temperatures can be used. Ammonia vapor is then exhausted from the solvent evaporator 91 . In most cases, the vapor then passes through a separation or rectification column ( figure 1 not shown in ) are separated from the water residue and then flow into the liquefier 92. The liquid ammonia is then stored in a high pressure collector ( figure 1 not shown in). For conditioning, the air stream from the connected refrigeration customer is sent to heat exchanger 93 where the cooled ammonia i...

Abstract

A heat transfer device and its manufacturing method are provided. The heat transfer device has a heat transfer member defining a heat exchange surface with which a heat transportable medium contact in use and via which heat is transferable between the heat transportable medium and a working medium, and a device body for containing the heat transportable medium. The body of the device defines a first chamber (11), a second chamber (12) and a third chamber (13) which is in fluid communicable relationship. The body is configured to allow the heat transportable medium fluid to pass from the second chamber (12) to the first chamber (11) and then to the third chamber (13), or from the third chamber (13) to the first chamber (11) and then to the second chamber (12), and the second chamber (12) is sandwiched or positioned between the first chamber (11) and the third chamber (13) in the body.

Description

technical field [0001] The present invention relates to, but is not limited to, heat transfer devices or heat exchangers for use in, for example, absorption refrigeration systems, methods for manufacturing such devices, exchangers or systems, methods for operating such devices, exchangers or systems Methods and heat transfer or transfer media for use in such devices, exchangers or systems. Background technique [0002] In refrigeration units and heat pumps, heat and mass transfer occurs across the surfaces of the heat exchanger. As a result, for example heat transfer from fluid to fluid, from fluid to vapor or from vapor to fluid is possible. Large pressure differences between vapor and fluid phases and corrosion stability due to chemically aggressive media represent only some of the challenges for reliable heat exchangers in these fields of application. [0003] In conventional absorption refrigeration systems, for example, heat exchangers are made of tube bundles of cons...
