1. An adsorption/absorption split type air conditioning unit comprising:
a first component comprising (i) one or more compressors, and (ii) a condenser, wherein at least one of said one or more compressors is a thermal compressor operating in a vacuum; and
one or more second component(s), separate and remote from said first component, said one or more second component(s) each being provided in a dedicated housing and comprising an evaporator, wherein the one or more evaporator are selected from a group consisting of: (a) falling film tubular (horizontal/vertical), (b) rising/falling film tubular, (c) forced circulation (tubular/plate), (d) plate-type, (e) falling film plate, and (f) any combination of (a)-(e), with or without enhanced surface treatment for aiding surface evaporation;
each remotely located said one or more second component(s) including said evaporator connected to said at least one of said one or more compressor for adsorption or absorption in the first component through said one or more suction line(s) and one or more liquid line(s);
one or more of said suction line(s) providing discharged refrigerant fluid from each said evaporator through said one or more compressors to said condenser; and
said one or more liquid line(s) conveying refrigerant fluid to each said evaporator from said condenser,
each said evaporator being configured to serve as an air-handler for cooling room air and vaporize the refrigerant to enable an adsorption/absorption split type air conditioning unit function without a chilled water circuit to the evaporator.
 
11. A method for split level adsorption refrigeration using said adsorption/absorption split type air conditioning unit as claimed in claim 1 wherein the method comprises:
providing said first component comprising said one or more compressors and said condenser, wherein at least one of said one or more compressors is the thermal compressor operating in a vacuum;
providing said one or more second component(s) separate from said first component, each said one or more second components being provided in a dedicated housing and comprising an evaporator, wherein the evaporator is selected from the group consisting of: (a) falling film tubular (horizontal/vertical), (b) rising/falling film tubular, (c) forced circulation (tubular/plate), (d) plate-type, (e) falling film plate, and (f) any combination of (a)-(e), all with or without enhanced surface treatment for aiding surface evaporation;
connecting each said evaporator to the condenser through said one or more suction line(s) and said one or more liquid line(s) for inlet and outlet of refrigerant fluid;
discharging refrigerant fluid from each said evaporator through said one or more said suction line(s) into said one or more compressor(s) and therethrough to said condenser;
conveying refrigerant fluid through said one or more liquid line(s) to each said evaporator from said condenser.
