Conflated Air Conditioning System

Abstract

The primary object of the present invention is to provide a basis for the design and implementation of a heating and cooling system (air conditioning system) which will reduce energy consumption over the presently used systems, reduce equipment and installation cost, and reduce maintenance cost. The use of this invention can mostly be used (but not only) in any commercial or residential building requiring heating and cooling. This system allows heating and cooling with water-cooled, self-contained air conditioning units or heat pumps, served by 2-pipe or single pipe, viable without heat pump operation, and can utilize waterside economizer. The system eliminates the need of having separate condenser water and separate hot water piping connections to the self-contained terminal air conditioning units. In cooling mode, the 2-pipe system or the single pipe system serves as condenser water piping from the cooling tower, and at appropriate outdoor temperature the colder water is supplied through the same piping to the economizer coil, thus saving the compressor work. At heating mode, the 2-pipe system or single pipe system from the boiler serves as hot water piping to the same coil serving also as the economizer coil.

The embody of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . Air conditioning and heating system compromising of: water-cooled self-contained air conditioning unit or heat pump with economizer coil; cooling tower; boiler; circulating pumps; the system components are connected with 2-pipe or single-pipe distribution piping with valves as condenser water piping, or hot water piping. 
     
     
         2 . The system as recited in  claim 1 , wherein the distribution piping is furnished with valves that can direct or control the flow to the condenser, or to the evaporator, to the economizer coil which serves both as cooling coil and heating coil, to the cooling tower, to the boiler. 
     
     
         3 . The system according to  claim 2 , wherein heat exchanger is inserted into distribution piping, or circulator is inserted to single-pipe distribution piping connected to air conditioning unit, or to heat pump, or expansion tank is connected to piping.
