This study is focused on the iron and steel industry, petrochemical industry, food processing plant, etc. with the process products in maneuverability movement for industrial and commercial medium- and high-temperature environmental plant air-cooled conditioner machine system. Because of the high-temperature environmental in the process is needed the cooling equipment and the unit, as well as the working environmental for the operator to be comfortable, safe, and avoid heat effect operator health. It must need to design and development of air-cooled conditioner equipment system. In the particular, these are heavy industrial plants have the medium- and high-temperature environmental, high humidity, high pollution, high dust, high corrosion condition, etc. The general air-cooled conditioner equipment is hurt. It will need research special air-cooled conditioner machine system developed resistance to high temperature, high humidity, high pollution, high dust, high corrosion, high reliability, high quality components, and convenient maintenance in operation personnel and the environmental to thermal cooling. With the ambient temperature is between 35℃ and 80℃, because the environmental temperature of iron and steel industry, petrochemical industry, and processing plants in the control operational room maintenance temperature is between 15℃ and 25℃ with relative humidity is between 45% and 65%. Therefore, the development of medium- and high-temperature industrial special type air-cooled conditioner machine unit use eco-friendly refrigerant is R-124 and R-134a, the power is 3φ 460VAC/60Hz, the electricity consumption is lower than 2kW, 3kW, 6kW, and 9kW, and the cooling capacity is higher than 2,000 kcal/hr, 3,000 kcal/hr, 6,000 kcal/hr, and 9,000 kcal/hr. It will design a set of evaporation, condenser, electricity box, operating control box, compressor, expansion, cooling fan, oil separator, liquid-gas separator, dry filter, framework, and secondary cooler etc. It can apply to industrial plant in the medium- and high-temperature environment. It is possible to maintain a good and healthy comfortable with safe environment for the people in the space of the operating supply environment.
