Chiller is a kind of refrigeration equipment composed of refrigeration system, water system and electrical system. The core is the refrigeration system. The refrigeration system is composed of compressor, evaporator, condenser and expansion valve. The air cooled refrigeration system is a chiller that dissipates heat through one or more external rotor fans and the environment because its condenser (radiator) is finned.


Air Cooled Refrigeration System


The core advantages of air cooled refrigeration system:

It has its own refrigeration system, water pump, water tank, and control system. After arriving at the customer’s site, the customer can install it by himself, and it can be used in areas where water is scarce and cooling water is inconvenient.

Application fields of air cooled refrigeration system:

The air cooled refrigeration system is an integrated machine, which is widely used in plastic mold shaping, electronic equipment, chemical reaction, welding equipment, life science, surface treatment, ultrasonic cleaning, material processing, vacuum coating, vacuum equipment, semiconductor processing and other industries. It can accurately control the heat generated by modern industry, improve production efficiency and ensure production quality. There are many varieties and types and complete specifications.

Design of air cooled refrigeration system:

The air cooled refrigeration system is a monolithic structure with built-in water tank and water pump. The user only needs to connect the pipeline and power supply.

1. Product Features

The air cooled refrigeration system adopts scroll compressors of internationally renowned brands, equipped with double-threaded copper tubes to make condensers, evaporators and control components, so that the unit has the advantages of small size, low noise, large energy, long life, and easy operation. Its beautiful and exquisite shape design and reliable and stable performance are outstanding among similar products.

2. Design features:

Brand scroll compressor, high energy efficiency ratio, reliable operation, long life;

It adopts a special temperature controller for chiller, which has high temperature control accuracy and stable performance. , Full digital display, connected with external equipment, remote users and control room through RS485 interface, can realize multiple control functions (optional).

Multiple protection functions: compressor exhaust over-temperature, motor over-temperature, cold water antifreeze and other temperature protection; over-current, phase loss, reverse phase electrical protection; refrigerant system high and low pressure, oil level, water cut-off and other abnormal state protection.

Maintenance and management functions (optional) such as alarm, reminder, record, and retrieval can be set for the above protection functions.

Through remote communication, unmanned operation management is automatically realized according to the predetermined work plan.

Selected thermal expansion valves, solenoid valves, check valves and other control components ensure that the air cooled refrigeration system can work at high speed in a wide range of operating conditions.

The structure of air cooled refrigeration system:

Air-cooled condenser

The washable air-cooled condenser adopts enhanced heat exchange tubes, and the subcooling section is designed to increase the heat dissipation area. The design pressure of the fluorine side is 30bar to ensure the safety of the equipment.


The dry water tank coil evaporator/shell tube evaporator/plate evaporator is selected according to different types. The design pressure of the water side is 10bar; the design pressure of the fluorine side is 25bar. The evaporator is covered with 50mm thick soft closed-cell rubber and plastic sponge insulation material, which effectively prevents heat transfer between the evaporator and the outside air in the machine room, and reduces energy loss.

Electric control system

The main components are all made of vital parts to ensure the reliability of the unit operation. The unit control adopts the special temperature control control of the chiller, which makes the operation easier.

Water pump

The product adopts the integral structure of the motor and the pump body. The motor is a fully enclosed, air-cooled standard motor, and its size meets the national design standards.
