Abstract: The present invention relates to a novel high efficiency and low weight solar flat plate fluid heating device. Use of a translucent multi-wall top cover (14) with plurality of integrated conduits in combination with stepped multi-wall sheet absorber (21) results in reduced top losses while reducing weight of the device and fluid pressure drop. Blower/pump power reduces substantially enabling the use of PV operated blower/pump. Preheating of fluid entering the absorber is facilitated by the use of translucent multi-wall top cover (14). Multi-wall construction of the absorber (21) results in reduced hydraulic diameter thereby enhanced heat transfer. Further, stepped and/or parallel arrangement of the absorber (21) results in reduced fluid pressure drop. Material of the multi-wall sheet is selected from plastics, polymers, glass, metals, alloys etc. The novel device is capable of heating single or plurality of fluids simultaneously. Further, it can be effectively used at low ambient temperatures of the order of -20° C.

Abstract: The present invention relates to an energy efficient and inexpensive Freeze Concentration System (FCS) to selectively freeze solvent from a solution using Heat Pump (HP) with heat transfer surfaces to extract and deliver heat to freeze the solvent and melt the frozen solvent using the heat from the HP. This process involves refrigeration of the solution, crystallization of water and separation of the formed ice. One or more sets of the heat extracting and/or heat delivery surfaces are intermittently operated as either freezing or melting surfaces to concentrate solution in a batch process or batch wise continuous process. Conventional Niro process uses Scraped Surface Heat exchanger (SSHE). Its size is limited by the mechanism implemented for ice scraping, SSHE is expensive. This System does not scale well to large volumes because of SSHE. In recirculation, concentrate is mixed with the fresh feed. The system has to operate at much lower evaporator temperature to refrigerate concentrate continuously rather than fresh feed, which increases energy cost. Since condenser of the refrigeration system is air cooled, Coefficient of Performance (COP) is low. In novel FCS freezing and melting of frozen solvent is carried out while it is in contact with the heat exchange surface simultaneously or in sequence with a switching mechanism involving only two components in solution viz. freezer and melter thereby obviating the need for a scraped surface heat exchanger, recrystallizer and wash column. The compressed refrigerant vapor is condensed by means of delivering heat to frozen solvent at as low condensing temperature as possible instead of rejecting heat to ambient sink which makes system energy efficient. The compressor of the Heat pump may be directly driven by an engine, turbine or motor depending on the application.
