Abstract

An Immediate Heat Upgrading Absorption Air Conditioning System (IHUA System) uses Immediate Heat Upgrading Absorption Air Handlers (IHUA air handlers). In this system, an absorption solution consisting of a common salt and water is circulated through the IHUA air handlers to upgrade heat taken from a first air mass or water and release the upgraded heat to a second air mass immediately. Production of chilled water is avoided. An IHUA air handler has one or more Modular Evaporation-Absorption Panels (E-A panels) with two sets of heat transfer fin assemblies. An E-A panel has two closely spaced heat conductive walls enclosing a film evaporative zone and a film absorption zone that respectively exchange heat with air to be cooled and air to be heated through the two sets of fin assemblies. An IHUA system can also provide cool thermal storage by storing water and absorbing solutions. IHUA systems can be used in air conditioning buildings and moving vehicles. A Modular Regeneration-Condensation Panel (R-C panel). An Integrated Evaporation-Absorption and Regeneration-Condensation Panel (EA-RC panel) is also introduced.

Dependent claims

A heat upgrading absorption system for cooling or heating an air mass to be conditioned by taking heat in from a first mass of fluid at a first temperature and supplying heat to a second mass of fluid at a second temperature that is higher than the first temperature, one of the masses of fluid being the air mass to be conditioned, that comprises a first sub-system [denoted also as a Type A sub-system] that comprises one or more air handlers, each exchanging heat with the air mass to be conditioned, and each air handler comprises one or more Type A processing regions, and each Type A processing region comprises:

(a) a Type A enclosure surrounded by a Type A heat conductive wall;
(b) an evaporation zone [Zone A-1] and an absorption zone [Zone A-2] and a vapor passage between the two zones within the Type A enclosure;
(c) a first heat interaction zone [Zone A-3] that is outside of the Type A enclosure and is in heat communication with Zone A-1 through a first portion of the Type A heat conductive wall;
(d) a second heat interaction zone [Zone A-4] that is also outside of the Type A enclosure and is in heat communication with Zone A-2 through a second portion of the Type A heat conductive wall;
so that conduction of the following operational steps:
(a) introducing water into Zone A-1,
(b) introducing a first absorbing solution into Zone A-2,
(c) introducing the first mass of fluid into Zone A-3, and
(d) introducing the second mass of fluid into Zone A-4;
lead to the occurance of the following operational steps:
(a) heat transfers from Zone A-3 to Zone A-1 to thereby cool the first mass of fluid in Zone A-3 and vaporize water in Zone A-1 to form a first water vapor;
(b) the first water vapor flows through the vapor passage from Zone A-1 to Zone A-2 and is absorbed into the absorbing solution to thereby release the heat of absorption and form a second diluted absorbing solution;
(c) heat transfers from Zone A-2 to Zone A-4 to thereby heat the second mass of fluid in Zone A-4.
