Embodiment Construction

[0078] The environmental wind tunnel is a necessary testing facility in the process of R&D and design of many equipment such as automobiles. Through the temperature control system, the temperature in the environmental chamber is stabilized, and the temperature control requirements of related equipment in the wind tunnel are maintained. The wind tunnel test chamber can also be equipped with a pre-test chamber for immersion of vehicles at low temperatures. Therefore, the existing temperature control system in the environmental wind tunnel includes the main refrigeration system for the temperature control of the main environmental chamber, the temperature-controlled pre-test room refrigeration system for the pre-test room, and the standard refrigeration system for auxiliary cooling. The system can provide cooling for main fan motor cooling, fresh air and dehumidification units, and rainfall and snowfall systems. However, it is found through research that if the temperature contr...

Abstract

The invention relates to a temperature control system, apparatus and method of an environmental wind tunnel. The temperature control system comprises a cold accumulating device and a control device; the cold accumulating device is suitable to accumulating cold capacity and cooling the main environmental chamber of the wind tunnel; and the control device controls the cold accumulating device to cool the main environmental chamber when the preset temperature of the main environmental chamber is larger than or equal to the lowest allowable temperature of the cold accumulating device. By means of the temperature control system, apparatus and method of the environmental wind tunnel, the system energy efficiency of an environmental wind tunnel test system can be improved.
