Abstract

An investigation is to measure the performance of new concept system of air conditioning system undertaken into cooling needs for commercial and recreational temporary air conditioning (A/C) where powered by small engine replace electrical power supply source. A research was starting from literature review to understand the basic principle of air conditioning system and the requirement. From the information, the suitable component was select to accomplish the system function such as refrigerant type and small engine unit. As the result, R134a was most suitable and environmentally safe to use on this system. It has lowest global warming potential and for the same reason, four-stroke engine was use and it more reasonable from two stroke engine. Finally, the system was design by using the selected component from previous to form a complete system with basic component such as refrigerant’s compressor, evaporator, condenser, expansion valve and small petrol engine unit. The performance of this system was undertaken by experimentally. First experiment method is design to calculate the cooling load of one lecture room and aspect to be cool by using this system. Last experiment is the most important on these research, its was use to determine the COP(coefficient of performance) of this whole system operation. In PSM II, this system was successfully fabricated and has been test for performance. Both of the experiment was successfully done and the result of COP is 1.15.
