Abstract The use of renewable energy such as geothermal energy and solar energy to supply the required energy is one of the ways to combat the energy crisis in the world. In this research, the design of a geothermal heat pump system for heating the operating room environment is investigated. Nowadays, many modern industries need an environment free from particle pollution and without bacteria with clean room considerations. Air conditioning systems are a main tool to establish a comfortable and safe environment by maintaining Air quality and removal of pollutants in the indoor space. A clean room is an environment where the parameters of the number of airborne particles, temperature, humidity, air pressure and air flow are under control. Therefore, the purpose of this study is to eva‎luate the performance parameters of a clean room. In this study, the ventilation system with The minimum energy consumption has been studied, which obtains the energy needed for operating room ventilation from the heat energy of the earth. The results show that the air curtain has a great effect in reducing pollution and more favorable conditions if it meets an optimal velocity of the exit air. The main goals of this research are flow simulation, temperature distribution in the operating room, finally, checking the comfortable conditions of the operating room is a subject of study.
