Abstract: An Indirect Evaporative Cooler (IEC), when used as a precooling unit in the fresh air system, can achieve heat recovery through the use of exhaust air and is attractive for energy saving. In hot and humid areas, the IECs can also realize considerable latent heat recovery due to the possible condensation. Based on statistical data derived by numerical models of different types of IECs, this research developed simplified models for predicting the annual energy saving potential of IECs applied in practices in hot and humid areas. Results showed that the predicted values of simplified models can agree well with the simulated values. By integrating the fitted regression equations to building energy consumption simulation, a case study of a wet market in Hong Kong was conducted. Consequently, the IEC can achieve 43.8 ~ 56.4% energy saving to the HVAC system.
