The effect of input air properties on the efficiency of an air conditioning system with heat pipe heat exchanger (HPHE) has been investigated at pilot scale in this paper. Energy saving is the main purpose of using HPHE in this experimental air conditioning system. HPHE is a heat superconductor that acts with few temperature gradients between evaporator and condenser sections and with any heat pump. Mass flow, temperature & humidity are main design parameters of this air conditioning system. These parameters have effect on heat transfer coefficient & efficiency of the HPHE. The HPHE is used for pre-cooling and preheating. The experiments show that by using HPHE in an air conditioning system, we will save around 10-15% of energy in the evaporator and 40-65% in the condenser of the HPHE.
