Abstract

A secondary refrigerant fluid is cooled or heated in the operation of a multiple Tube-fins heat exchanger arranged in parallel for fins to conduct heat transfer with air being propelled by a multi-row bank of low profile brushless fans. Fluid is controlled to ascend the bank of tubes in unison rate for high efficiency heat transfer with air. Large temperature differential exists between air and fluid when conditioned fluid travels through the tubes for a relatively short distance. A system of components is so arranged that the fluid flow rate to every heat exchanger is preset and the “on” or “off” operation of any heat exchanger does not affect the flow rate destined for other heat exchangers. Fluid is not transported to a heat exchanger when it is not in operation saving energy. Each heat exchanger is controlled by an integrated thermostat so occupants can set the air conditioning operation individually independent of all other heat exchangers.
