摘要

An artificial climate room plays an important role in the research of an apparatus test and indoor/outdoor environment simulation. Generally, the refrigerator is used to decrease temperature to simulate outdoor environment, while a heater is used to increase the temperature to simulate the indoor environment. It would result in large waste if the temperature control method of artificial climate room is unreasonable. It causes energy waste because it takes too much time for control process stability, which is caused by the characteristics of controlled objects such as lagging, inertia and uncertainty. Thus it is necessary to design more reasonable control methods for energy conservation. The cooling capacity for simulating outdoor temperature varies widely, so multiform controlling means is adopted, such as frequency control for the refrigerator, on/off control and auxiliary heater. While the thermal chamber which is used for simulating indoor temperature is on a long-time delay, large inertia (forced disturb is not allowed), and a new type of immune controller is designed by learning from the functions of self-adjustment, antigen memory and immunity response in biology immunity systems. By the control method, it gets a smaller overshoot and a quicker response speed in the practical process of temperature control of an artificial climate room; thus it is considered to be an optimum energy conservation method. The control method can be widely popularized and applied in an HVAC system.
