dc.description.abstractThe escalating energy consumption in conditioning fresh air causes abundance of condensing heat energy wasted especially under the hot and humid climate. In this context, by installing energy recovery unit, thermal energy is transferred from outgoing to incoming air streams which recovers the wasted energy. The main objectives of this research are to evaluate the performance of stand-alone energy recovery unit and split unit air-conditioning system, to assess the performance of integrated system and to compare the performance between stand-alone air-conditioning unit and integrated system by varying parameters of temperature of 28ºC, 31ºC, 34ºC and 40ºC, relative humidity of 65%, 75% and 85% as well as air-velocity of 1 ms-1, 2 ms-1 and 3 ms-1. Experiment has carried out in a low-rise commercial office room within hot and humid environment. Efficiency and recovered energy of the energy recovery unit as well as Coefficient of Performance (COP) and cooling capacity of the split unit air-conditioning system are evaluated in the range of 42-78%, 0.4-3.4 kW, 1.0-2.6 and 0.7-1.9 kW respectively. COP, cooling capacity, potential energy recovered and carbon dioxide emission reduction of integrated system assessed are in the range of 1.5-4.0, 1.2-2.9 kW, 217-1849 kWh, RM 94-804, 0.1-0.9 MgCO2e respectively. T-test presents the performance of integrated system is statistically different and better than stand-alone unit due to its pre-cooling and dehumidification functions. In practical application, this research provides reference data on the application of energy recovery in split unit air-conditioning system for researchers, engineers and architects.en_US
