Air Cooled Chiller

1. Modular design

The modular combined structure makes the transportation, installation, commissioning and maintenance of the unit more convenient, and saves the transportation, installation and operation costs; the combination has high flexibility, which is conducive to energy regulation and control. Up to 32 compressors can be controlled to meet the load requirements of different buildings.

2. Automatic control

The operation and management of the unit are completed by the microcomputer control system, which is easy to operate and does not need professional management personnel; the unit automatically starts / stops the compressor according to the load, so that the unit can operate at the best economic point and save energy for users. All protection functions of the unit are complete, with fault self-test system, automatic balance of compressor wear and other functions.

3. Chiller appearance

The supporting frame and panel of the unit are made of high-quality stainless steel plate, which is precision processed by Japanese Amada sheet metal equipment. The anti-corrosion and anti rust ability of the unit is very strong, so it is not necessary to build a special machine room when it is placed outdoors.

4. Independent operation

The refrigeration system between modules is completely separated, and the operation of the system is controlled independently. There is no influence on each other when starting. The working time and working parameters of the unit can be set according to the cooling load.

5. Intelligent antifreeze

The double-stage automatic anti freezing protection is adopted to prevent the water system from being damaged due to the freezing of refrigerant water in the unit pipeline when the temperature drops in winter. When the unit passes the automatic heating operation or the water temperature increases after the water pump runs, it can automatically exit the anti freezing control.

6. User friendly

All the protection parameters have been set. The on-site installation only needs to connect the power supply and water supply pipeline, and use only needs to operate the computer controller.

三、Unit composition

Air cooled industrial chiller is mainly composed of compressor, air side heat exchanger, throttling mechanism (expansion valve), auxiliary refrigeration accessories and electric control system.

1. High efficiency scroll compressor

The unit adopts the international famous brand high efficiency flexible scroll compressor with strong liquid hammer resistance, ultra-high energy efficiency, superior performance, reliable operation and long service life.

2. Electronic expansion valve

The throttling element of the unit adopts electronic expansion valve to accurately control the refrigerant flow to ensure that the refrigeration system has the best performance.

3. High-efficiency fin heat exchanger

High-efficiency copper tube high-quality aluminium fin coil heat exchanger is used. Aluminum foil is stamped and formed through a complete set of inlet stamping line. Copper tube is closely combined with aluminium sheet and has the best heat conduction efficiency.The inner threaded copper tube not only increases the heat exchange area, but also enhances the disturbance performance of the refrigerant.

4. High-efficiency shell-and-tube heat exchanger

High efficiency shell-and-tube heat exchanger is used in the water side heat exchanger of the unit, which has high heat exchange efficiency, more uniform distribution of refrigerant by diverter, low water quality requirement and convenient maintenance and cleaning.

5. High Efficiency and Low Noise Axial Flow Fan

The fan adopts forward sweeping twisted plate blades with excellent aerodynamic performance, and cooperates with high-efficiency motor to achieve low noise, high efficiency and long service life.
