A Vapor Pressure Enhancement Air Cooler, designated as a VPE air cooler, a Vapor Pressure Enhancement Air Heater, designated as a VPE air heater, and a dual purpose integrated Vapor Pressure Enhancement Air Cooler/Heater, designated as a VPE air cooler/heater are introduced. A VPE air cooler 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 air cooling zone (Z-En), a vapor pressure enhancement zone (Z-VPEn) and a second vapor condensing zone (Z-Xn). There are a set heat transfer tubes with fins to provide water evaporation surfaces in the evaporation air cooling 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; there are condenser tubes in the condensation zone. A first vapor is absorbed and second vapor is generated in the enhancement zone: the second vapor is condensed in the condensing zone. Outdoor air, cooling water or air/water combination is used to remove the heat of condensation. The construction and operations of a VPE air heater are similar to those of a VPE air cooler.
