5. No need for voltage transformation equipment, simple installation and low cost
Evaporative Cooler Water Chiller
Ground source heat pump screw units, ground source heat pump units mainly use groundwater or soil below 100 meters as the exchange medium to achieve energy-saving operation of the main unit, and their energy-saving rate can reach 30% to 40%. All these units are equipped with original imported compressors from internationally renowned brands (such as Taiwan Hanbell, Germany Bitzer, the United States Wheelbase, Japan Sanyo, etc.), and the main unit components are mainly from international first-line brands. The condenser and evaporator are independently designed and produced by the company, which can be optimally matched with the compressor to achieve the highest energy efficiency ratio. This unit is equipped with our independently developed falling film evaporator, making the unit more energy-efficient and efficient. Next to it is the display of the Internet of Things control system we have matched, which realizes the intelligent control of the central air conditioning system and achieves energy-saving effects.
