The central air-conditioning project of the factory should choose the central air-conditioning that is suitable for large areas. The following are common:Modular unitChange the traditional Freon pipelines to water pipelines, combine indoor and outdoor units into refrigeration units, and change indoor units to fan coil units. The refrigeration process is carried out by using the heat exchange of refrigerant water. Since the modular machine can automatically adjust the number of start-up units according to the requirements of the cold load.Screw chillerScrew type chillers are large and medium-sized refrigeration equipment that provide chilled water, and are often used for air conditioning in national defense research, energy development, transportation, hotels, restaurants, light industry, textiles and other departments. Screw chiller is a complete refrigeration system composed of screw refrigeration compressor unit, condenser, evaporator, and automatic control components and instruments. It has the advantages of compact structure, small size, small footprint, convenient operation and maintenance, and stable operation. Its single unit cooling capacity is from 150-2200KW, which is suitable for medium and large projects.
