HEAT RECOVERY SYSTEM
After installation of heat recovery unit on air units of spray booth, heat of waste air will be recovered by heat recovery unit to preheat fresh air. This heat exchange core inside heat recovery unit increases the temperature of initial air before entry of heat unit, then attains energy conservation.
During heat spraying process of spray booth, intake fan and exhaust fan work together; burner ignites inside heat exchanger and produce large heat; outside fresh air flows to heating unit after filtered under fan working. After that, the fresh air can be heated inside the heating unit and enters to booth for spraying. Due to the function of the exhaust fan, the waste air produced by spraying in the booth will be released to the atmosphere through the exhaust air duct after being filtered by fiberglass filter in the booth floor and in the exhaust air unit. Therefore, the large heat energy in waste air will be lost.
Working Principle of Heat Recovery System in YOKISTAR spray booth
Outside fresh air will flow through Heat Recovery System before entry of heat unit; waste air will flow through Heat Recovery System before release to the atmosphere; these two air flow will exchange heat inside core of Heat Recovery System. Fresh air cleanness can be ensured by the complete isolation of waste air and fresh air. Therefore, there is a significant rise in fresh air temperature as well as a temperature drop in waste air before release. The energy consumption of heating fresh air to required heat spraying temperature is dramatically decreased accordingly.
