Modeling of automobile air conditioning systems

Chung-Lun Li;Shung-Luen Chung;Jing-Nang Lee

  This paper studies the dynamics of temperature and humidity of air in a car compartment by the concept of enthalpy in analyzing the heat exchange involved.With heat change decomposed into sensible heat and latent heat,we are able to derive dynamics of temperature and humidity of the car compartment after taking into account of the difference of ASHF(apparatus sensible heat factor) and RSHF(room sensible heat factor).These two formulas are used in conjunction with two control strategies on flow rates of supply air to simulate the intended controlled car compartment at constant enthalpy and of constant temperature.The contribution of this work is to provide a framework for automobile air-conditioning analysis and simulation.……
