Thermal environment and waste heat recovery of high-radiant heat workshop

Abstract

The high temperature of the high radiant heat reservoir workshop, the poor working environment of workers, and the long-term heat stress will hinder the brain power and cardiac function, which is an important environmental factor that causes unsafe behavior, and the waste heat loss in the workshop is serious. Taking the heat reservoir power of 10 kW as the research object, the role of heat shield under different water flow conditions in the waste heat recovery and reduction of workshop temperature was analyzed. The results show that when the mass flow rate of cooling water is 0.7 kg/s, the average indoor temperature is 22.39 °C, the cooling range is 39.14 %, and the waste heat recovery efficiency is 84.4 %, and the heat recovery effect is obvious. At the same time, the fitting relationship between outlet water flow and water temperature is obtained. The research results can provide a reference for the improvement of the thermal environment and waste heat recovery and utilization of the actual high-radiation heat workshop.
