Product Description

High quality air cooled scroll chiller with shell and tube evaporator 5Ton cold water machine
Cold water machine also called chilled water machine, cooling water machine, water chiller, industrial chiller. 

A cooling air chiller, also known as a cold water machine or air-cooled chiller, is a device used to remove heat from a process or equipment by circulating chilled air. It consists of a compressor, condenser, evaporator, and a fan. The process begins with the compressor compressing a refrigerant gas, which increases its temperature and pressure. The hot gas then flows to the condenser where it releases heat to the ambient air and condenses into a liquid.

The liquid refrigerant then moves to the evaporator where it undergoes a phase change, absorbing heat from the process or equipment that needs to be cooled. The chilled air produced by the evaporator is circulated using a fan and directed towards the target area or equipment. The warm refrigerant gas then returns to the compressor to complete the cycle.

A cooling air chiller is commonly used in industrial applications, including film blowing machines, injection molding machines, printing presses, laser cutting machines, and various other processes and equipment that generate heat during operation. It helps maintain optimal operating temperatures and prevents overheating, ensuring efficient and stable performance of the equipment.

A cold water chiller, also known as a water chiller or water-cooled chiller, is a mechanical refrigeration device used to cool water to a desired temperature. It is commonly used in industrial and commercial applications to provide cooling for various processes, equipment, and environments.

The basic principle of a cold water chiller involves the circulation of chilled water through a closed-loop system. The chiller consists of key components such as a compressor, condenser, evaporator, expansion valve, and a water circulation pump.

Here's a brief overview of how a cold water chiller works:

1. Compression: The compressor in the chiller pressurizes a refrigerant gas, typically a type of refrigerant such as R-134a or R-410a, which increases its temperature.

2. Condensation: The high-pressure, high-temperature refrigerant gas flows into the condenser, where it releases heat to the surrounding air or a separate cooling medium, such as a cooling tower. As a result, the refrigerant condenses into a high-pressure liquid.

3. Expansion: The high-pressure liquid refrigerant passes through the expansion valve, which reduces its pressure and subsequently its temperature. This causes the refrigerant to change into a low-pressure, low-temperature mixture of liquid and vapor.

4. Evaporation: The low-pressure refrigerant enters the evaporator, which is a heat exchanger. Here, it absorbs heat from the water circulating through the evaporator, causing the refrigerant to evaporate and return to its gaseous state. This heat absorption process cools down the water.

5. Circulation: A water circulation pump moves the chilled water from the evaporator to the application or process that requires cooling, such as air conditioning systems, industrial processes, or data centers. The heated water is then returned to the chiller for recooling.

The cycle repeats as long as the chiller is operational, maintaining a constant flow of chilled water to meet the cooling requirements.

Air-cooled chiller is a common industrial cooling equipment with the following advantages:

Independent cooling system: The air-cooled chiller adopts an independent air cooling system and does not require additional cooling water sources or cooling towers. This makes installation and operation relatively simple, saving installation and maintenance costs and space.

Wide range of applications: Air-cooled chillers are suitable for various industrial applications, including plastic processing, refrigeration and air conditioning systems, machining, printing and paper making. They provide reliable cooling for different equipment and processes.

High efficiency and energy saving: The air-cooled chiller adopts air cooling method and uses forced fans to circulate the air and take away the heat. Compared to traditional water-cooled systems, they do not require additional water pumps and cooling towers, thus saving energy and operating costs.

Flexibility and mobility: Since they do not need to be connected to an external cooling water source, air-cooled chillers are more flexible and can be moved to different locations more easily. This is useful for applications that require movement or changes in work location.

Easy maintenance: Compared with water cooling systems, air-cooled chillers are easier to maintain. There is no need to deal with problems such as scale, water treatment and water pump maintenance, reducing the complexity and cost of maintenance work.

Small footprint: Air-cooled chillers have a relatively small footprint as they do not require a cooling tower and water cooling system. This is very advantageous when space is limited.

However, it should be noted that air-cooled chillers may be slightly less efficient than water-cooled systems in heat dissipation efficiency, especially in high-temperature environments. In addition, since air cooling requires the use of fans, noise and vibration may occur. Therefore, when selecting cooling equipment, it is necessary to comprehensively consider the advantages and disadvantages based on specific needs and process requirements, and weigh various factors.
