Industrial Chiller Integrated Cooling Water System Screw Type Integrated Water-cooled Screw Chiller
Water-cooled screw integrated chiller is a chiller product that integrates screw compressor, condenser, evaporator, electronic control system, water tank, water pump, pipeline and other basic chiller components into one unit. Since the water pump tank and pipelines of the integrated chiller have been connected at the chiller factory, the chiller is easy to install and only needs to be connected to the cooling tower and the user. It is particularly convenient for factories that do not know how to install chillers.
The main advantages of water-cooled screw integrated chiller are as follows:
Small space occupied: multiple components are integrated into one unit, the unit is smaller in size and takes up less space, and is suitable for places with limited space.
Convenient installation: Since multiple components are integrated into one unit, it is more convenient to install and easier to maintain and maintain.
Energy saving and environmental protection: The optimized unit design and the adoption of new energy-saving technology enable the water-cooled screw integrated chiller to make full use of energy, save energy and protect the environment.
Stable operation: The screw compressor has a high compression ratio and low operating speed, stable refrigeration effect, low noise, and stable and reliable operation.
Precise control: Equipped with an advanced automated control system, precise control and management of the refrigeration system can be achieved to ensure the stable operation of the air conditioning system.
In short, the water-cooled screw integrated chiller is a chiller product with compact structure, energy saving, environmental protection, stable and reliable performance, and is widely used in air conditioning systems in large commercial complexes, factories, office buildings, hospitals, supermarkets and other places.

The working principle of the water cooled screw chiller is: When the unit is refrigerated, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder. After the compressor performs work, the refrigerant vapor is compressed into high-temperature and high-pressure gas.
Enter the condenser through the exhaust pipe. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water, while the refrigerant gas is condensed into a high-pressure liquid. The high-pressure liquid from the condenser enters the evaporator after being throttled and pressure-reduced by the thermal expansion valve. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes, so that the chilled water is cooled down and becomes the required low-temperature water. The vaporized refrigerant gas is sucked in by the compressor again for compression, and discharged into the condenser, so that it goes round and round, and circulates continuously, so as to realize the cooling of the chilled water.
The chilled water from the unit enters the indoor fan coils, variable air volume air conditioners and other terminal devices, and exchanges heat with convection air indoors. In this process, the water absorbs the heat of the indoor air (dissipates heat to the indoor air). While the temperature rises, the indoor air temperature drops after passing through the indoor heat exchanger, and is driven by the fan to send it into the room, thereby reducing the indoor air temperature, and the chilled water after the temperature rises reenters the unit under the action of the water pump. Circulation, so as to achieve the purpose of continuous refrigeration.
