The present invention relates to a coating booth that can improve the drying efficiency by improving the circulation method of the hot air during the drying process, and also maximize the energy efficiency according to the scale-down of booth equipment and fuel saving.;The present invention arranges the air supply chamber to one side of the booth main body and uniformly heats the hot air supplied into the booth by heating the hot air primarily heated in the air supply chamber during the drying process with the electric heater at the upper part of the booth main body. In addition, the damper and the circulation fan are installed in the air supply chamber to adjust the flow rate slowly, thereby circulating not only the hot air circulated through the booth body but also the hot air of the heating chamber, and supplying it by heating the secondary heat with the electric heater. By reducing the heat loss as much as possible, the heat quantity of hot air supplied to the booth body can be increased in a short time, and it can be supplied uniformly.The fuel saving type has improved the hot air circulation method that can induce a stable flow of hot air and improve energy efficiency according to fuel saving. To provide a painting booth.;Paint booth, air supply chamber, exhaust chamber, drying process, hot air circulation furnace, heat loss reduction, energy efficiency increase
