“…A finned heat pipe was used to increase convective heat transfer between the primary air and the heat pipe, with different methods of heat eliminations from the condenser sections such as water sprayer on condensation section surface, the outdoor air is precooled by air washer before passed through the condensation section, the use of porous ceramic water container fitted around condensation section to assure even distribution of water. Also, In the literature many research studies conducted on heat pipes applications in building cooling includes HVAC systems [21]- [24], and heat recovery systems [25]- [28]. …”

Abstract-Indirect evaporative coolers are one of the most possible alternatives to conventional cooling methods for building air-conditioning. It utilizes evaporation of water to cool the air, consumes much less power, and employs no harmful refrigerants comparing to other traditional cooling cycles such as vapor compression coolers. This paper presents a mathematical model and experimental investigation of thermal performance of an indirect porous ceramic evaporative cooler with integrated heat pipe for heat transfer. It is shown that good agreement was achieved between the computer model and measured parameters of the cooling system. In the regions with hot and dry climates the system can be an environmentally friendly and energy efficient cooling system. Index Terms-Indirect evaporative cooling, heat pipe, porous ceramic, dew-point effectiveness.

This paper deals with the waste heat recovery using heat pipe heat exchanger. Heat pipe is a device which carries the heat from high temperature region & ejects it to the cold or low temperature region. The advantage of using a heat pipe over other conventional methods is that large quantities of heat can be transported through a small crosssectional area over a considerable distance with no additional power input to the system. The heat pipe heat exchangers are used in heat recovery applications to cool the incoming fresh air. Two streams of fresh and return air are connected with heat pipe heat exchanger to investigate the thermal performance and effectiveness of heat recovery system. The aim of this project work is to investigate the thermal performance and effectiveness of heat pipe heat exchanger for heat recovery applications by measuring the temperature difference of warm and cold air through the evaporator and condenser side. The hot-air temperature increased from 60 to 90 0 C; the heat-transfer rate increased slightly. The mass flow rate of hot air increased from 0.30997, 0.4643, 0.4889, 0.508 kg/s led to a slight increase in effectiveness. As the hot-air temperature increases from 60 to 90 0 C, the effectiveness slightly increased.
