Experimental & Theoretical Investigation of Pressure Drop at HPHE1 in Air Condition Systems

In order to energy saving in air condition sys tems, using ofHPHE is the style that chose in these experimental. Hphe used for precooling and preheating. Hphe is an ex tra heat conductor that acts with few temperature gradients between evapora tor and condens er. Hphe act with any heat pump. Using of hphe in air condition systems, saves J0- I5% energy in evaporator of hphe as pre cooling and 40-60% in condenser of hphe as preh eating. Correct work ofHPHE correlate to various parameters, similar pressure drop. In this paper, we build an hphe and compare pressure drop at theoretical manner with experimental in air condition system.
