Thermal analysis of heat pipe air conditioning (HPAC) system with vertically-installed adiabatic.

This paper investigates the implementation of heat pipe in the air conditioning system, specifically in an air circulating room. The use of air conditioning system in an air circulating room may increase the cooling load of the evaporator. In this experiment, the heat pipe is utilized for reducing the inlet air temperature in order to reduce the cooling load of the evaporator. Thermal analysis of the Heat Pipe Air Conditioning System (HPAC) is conducted with variation of vertically-installed adiabatic and initial air cabin temperature of 30°C with Air Conditioner (AC) setting temperature of 20°C; 18°C; 16°C. The thermal analysis is then compared with the HPAC without the adiabatic. The result shows that the utilization of vertically-installed adiabatic in the heat pipe of the HPAC decreases the inlet air temperature with cooling load of 5,981 kW; 6,978 kW; 7,477 kW, respectively to the AC setting temperature, compared to the HPAC without adiabatic with the result of 6,48 kW; 7,477 kW; 8,474 kW. The HPAC with vertically-installed adiabatic shows a lower energy use within the range of 29,1% – 37,7% for the AC compressor and 16,6% – 23% according to the cooling rate. The results indicate that the implementation of heat pipe with vertically adiabatic in the air conditioning system in a circulating room is more effective compared to without using the adiabatic.
