Summary

The energy efficiency is of importance in air conditioning systems for automobiles. The present article provides a new type air conditioning system for automobiles in which energy loss is small in comparison with the previous system. In the system, a desiccant is installed in the air conditioning system for controlling both temperature and humidity. The control is performed by an electromagnetic control valve, which controls an inclination of the rotating plate of a compressor. It is difficult to control both temperature and humidity precisely, because there are some delays in the control due to the time of heat exchange and that of coolant flow from the actuator (electromagnetic valve) to the evaporator. In order to have precise control, this article also presents a method of control with consideration of control delays. The energy of our system is compared with that in the previous conventional system in the same condition. It is shown that our controlled results and energy efficiency are better than those in the previous system. [Reprinted with permission from Elsevier. Copyright, 2006].
