How to achieve energy saving and high efficiency in integrated chillers

The integrated chiller saves energy because of its low condensing temperature. The integrated chiller integrates water-cooled units, computer room civil engineering, cooling towers, cooling pumps, cooling water pipelines, valves, instruments and measurement and control devices. It has the advantages of small size, high efficiency, low noise, long life, simple operation, high efficiency and energy saving. . The condensation heat of the refrigerant of the dual high-efficiency integrated chiller is taken away by the latent heat of water evaporation, and its condensation temperature is 5～8℃ lower than that of water-cooled units and 10～15℃ lower than that of air-cooled units. When the condensing temperature increases by 1℃, the energy consumption of the unit will increase by about 1.9%, and the cooling capacity will decrease by about 1.1%.

　　1. The condensation heat of the refrigerant of the dual high-efficiency integrated chiller is taken by the latent heat of water evaporation, and its condensation temperature is 5～8℃ lower than that of water-cooled units and 10～15℃ lower than that of air-cooled units. When the condensing temperature increases by 1℃, the energy consumption of the unit will increase by about 1.9%, and the cooling capacity will decrease by about 1.1%. Therefore, the integrated chiller saves energy because of its low condensing temperature.

2. The integrated chiller adopts an evaporative condenser, which integrates a shell and tube condenser, cooling tower, circulating pool, circulating water pump, and water treatment instrument, which can minimize the amount of installation engineering and the total investment is lower than the use. The total cost of other condensation methods.

　　3. The microcomputer control system has powerful functions such as safety protection, communication, fault judgment, and automatic adaptation. The ultra-thick overall hot-dip galvanizing process is adopted, the outer shell is a double-layer heat-insulating sleeve type, and the panels are all anti-corrosion materials. The equipment does not need to be maintained, so the operating cost is low.

　　4. The evaporative condenser adopts an elliptical coil, which increases the surface area of ​​the coil and enhances the air and water flow characteristics outside the interval tube coil, and improves the heat exchange efficiency. Its low water consumption rate, corrosion resistance, small footprint, easy maintenance and installation.

5. Two compressor options: screw compressor with unloading energy control device, which can realize multi-stage or stepless energy adjustment; fully enclosed scroll refrigeration compressor has high efficiency, low noise, low vibration, reliable operation and long life. Etc.
