Abstract

An air conditioning system comprising a compressor, condenser and evaporator as functioning components in a primary loop for moving a working fluid in a continuous and automatic cycle of operation between such components. The system includes a plurality of zones through which the air to be conditioned is moved. The zones each include stacked horizontal tubes in a single coil with vertical heat exchanging fins in a parallel array with the tubes of each stack extending through the fins. A wrap-around heat pipe with first parallel tubes adjacent to the input of such zones and with second parallel tubes adjacent to the output of such zones and parallel horizontal lines coupling the first and second parallel tubes.

Claims

1. An air conditioning system comprising a compressor, condenser and evaporator as functioning components in a primary loop for moving a working fluid in a continuous and automatic cycle of operation between such components, the system including a plurality of zones with cooling coils therebetween and through which a single linear flow of air to be conditioned is moved, the system also including a wrap-around heat pipe with first generally vertical parallel tubes with upper ends and lower end adjacent to the input of such zones and with second generally vertical parallel tubes with upper and lower ends adjacent to the output of such zones and upper and lower parallel horizontal lines with the upper line coupling the upper ends of the first and second parallel tubes and with the lower line coupling the lower ends of the first and second parallel tubes.

2. The system as set forth in claim 1 wherein the lines coupling the input include valves for varying the flow rate.

3. The system as set forth in claim 1 wherein the input and output include horizontal pipes.

4. The system as set forth in claim 1 and further including a flow control orifice.

5. The system as set forth in claim 1 and further including a magnetically coupled valve.

6. The system as set forth in claim 1 and further including a reverse Venturi.
