The performance of cooling coil unit (CCU) can directly influence the performance of ventilating and air conditioning (HVAC) system. In this paper, a dynamic CCU model was obtained by identifying the unknown parameters of existed effectiveness model. Five different conditions information is used to identify five model parameters by an optimal method. Unlike existed effectiveness model, the identified model can be simply determined by flow rate of chilled water, the temperature and humidity of return air and temperature of supply chilled water without requiring geometric specifications, which is very convenient in real engineering application. It was validated by five different experiment conditions on a CCU. The experiment results show that the identified model has a high accuracy despite changing the temperature and volume of chilled water.
