Temperature control system of high-temperature test room

Abstract

The invention discloses a temperature control system of a high-temperature test room, belongs to the technical field of temperature control, and provides a temperature control system capable of realizing regional uniform quick heating. According to an adopted technical scheme, the inner side wall of the high-temperature test room is uniformly provided with a plurality of groups of fixed temperature heating systems; each group of fixed temperature heating systems consists of a temperature sensor and two uniform heating devices; each uniform heating device consists of a heating box and a flat air radial blower which is arranged on the top of the heating box; an electrical heating tube is arranged in the heating box; each group of fixed temperature heating systems is provided with a group of corresponding temperature control devices; and each group of temperature control devices mainly consists of a temperature controller, a controller relay and an alternating current contactor. The temperature control system is suitable for the field of coal mine.

Description

technical field [0001] The invention relates to a temperature control system for a high-temperature test room, belonging to the technical field of temperature control. Background technique [0002] As a temporary shelter for the self-protection facilities of underground personnel in case of unexpected accidents, the mine rescue cabin may encounter high temperature accidents, so the rescue cabin should have the ability to withstand the instantaneous high temperature of the external environment and the continuous high temperature resistance Therefore, it is of great significance to test the continuous high temperature resistance of the rescue chamber. [0003] Generally, the rescue cabin is placed in the high-temperature test room, and the continuous high-temperature resistance test of the rescue cabin is carried out. At present, most high-temperature test rooms adopt the central air-conditioning heating control scheme or the oven heating control scheme. The heating time of th...

Problems solved by technology

[0003] Generally, the rescue cabin is placed in the high-temperature test room, and the continuous high-temperature resistance test of the rescue cabin is carried out. At present, most high-temperature test rooms adopt the central air-conditioning heating control scheme or the oven heating control scheme. The heating time of the central air-conditioning is long, and the temperature difference Large; the heating time of the oven is short, but because most of the ovens are controlled by silicon controlled voltage regulation, the heating control cannot be carried out in different areas, and the real-time data of multiple temperature measurement points in the high temperature test room cannot be observed at the same time. temperature
