A VPE-chiller comprises multiple pressure processing zones and is based on absorption vapor pressure enhancement operation. It comprises multitude of processing zones, Z-1, Z-2, ..., Z-N that are operated under pressure P1, P2, ..., PN. Each pressure zone (Z-n) contains a water evaporation zone (Z-En), a vapor pressure enhancement zone (Z-VPEn) and a second vapor condensing zone (Z-Xn). There are a set of rotating discs (11) to provide water evaporation surfaces in the evaporation zone; there are flat heat conductive tubes for forming falling films of absorbing solution and falling films of water in the vapor pressure enhancement zone (9); there are condenser tubes (13) in the condensation zone (10). A first vapor is absorbed and second vapor is generated in the enhancement zone (9); the second vapor is condensed in the condensing zone (10). Outdoor air, cooling water or air/water combination is used to remove the heat of condensation. The construction and operations of a VPE-heater is similar to that of a VPE-chiller. |
