product overview

Ordinary air-cooled screw chillers consume electrical energy through a compressor, use refrigerant as a carrier, transfer the heat of water to a condenser, and then use a fan to dissipate this heat, Thus obtaining low-temperature water. Throughout the entire working process, the compressor consumes electricity as a percentage of the total energy consumption of the unit90%above. The screw type naturally cooled air-cooled chiller unit launched by Nuobing directly obtains cooling capacity from low-temperature air outside during transitional seasons and winter, thereby obtaining low-temperature water. whole process In China, only the fan consumes electricity, while the compressor operates at partial load or completely stops, saving energy consumption90%The above greatly reduces the operating costs of the unit and brings higher economic benefits to customers.In the fields of energy conservation and environmental protection, new energy, biopharmaceuticals, optoelectronic technology, marine engineering, new materials, high-end equipment manufacturing support, chemical fiber, plastic, food, aerospace, military industry, research institutes, painting, electroplating, electronics, automobiles, hydrogen energyPlaces that require year-round cooling capacity,Efficient and energy-saving customers and industries have been widely used.

Product Features

1 Efficient and energy-saving operation in ultra-low temperature environments: meeting the requirements of ultra-low temperature environments below zero40Normal cooling operation,Compared to ordinary low-temperature air-cooled screw chillers, it operates throughout the year in low environmental conditions Under warm working conditions, the Nuobing naturally cooled air-cooled chiller can fully utilize low-temperature air to produce constant low-temperature water without the need for compressors to consume electricity. Therefore, natural cooling units are more energy-efficient, have lower annual operating costs, and can achieve lower ambient temperature cooling operation；
