摘要

Cooling technology with normal vapour compression cycle relies on electricity to increase and decrease the pressure hence the temperature, within its cycle. Passive cooling using heat pipe heat exchangers is being applied to the refrigeration cycle components to assist with temperature reduction of the cooling process. The return and supply air temperatures of an evaporator and condenser are being precooled by passive cooling equipment to assist in reducing the compressor work done. Computational fluid dynamics software is being used to run simulations and results are presented in terms of temperature, contour, velocity vectors and flow patterns. The objective of this study is to investigate and simulate air around a circular air cooled evaporator and condenser tube for an air conditioning system. The tube from the evaporator is a row of five copper tube (10mm OD) exposed to a room temperature of 297K and the tube for the condenser is exposed to an ambient air of 300K. The system is set to an evaporating temperature of Te=278K and the condensing temperature of Tc=319K. An air gap between the heat pipe heat exchanger and the tube where the simulation of heat transfer is assumed to be the key process is discussed. The end results of the air outlet of the evaporator and condenser with the effect of the heat pipe heat exchanger attached to it are discussed. It is found that the operating temperature reduced when a heat pipe heat exchanger is attached to the components. Increasing the heat transfer rate between the heat pipe and the component’s tube will increase the system capacity.
