Chillers are divided into air-cooled chillers and water-cooled chillers. The working principle diagram of air-cooled chillers is as follows

Working Principle of air-cooled chiller

The air-cooled chiller uses a shell and tube evaporator (or tank with coil) to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load from the water and cools the water to produce cold water. The heat is brought to the finned condenser through the action of the compressor. Then it is lost to the outside air by the cooling fan (wind cooling)

Features of air-cooled chillers：

1、The air-cooled chiller does not need to be installed with a cooling water tower and is suitable for environments with poor impurities. (It is easy to mix impurities in the cold water tower, and the dust will block the cooling water circulation loop, causing the cooling capacity to drop).

2、Air-cooled chillers are most suitable for areas with poor water quality, and can save other accessories for chillers.

3、With a large-capacity condenser, it can be easily operated even in heat.

4、Minimize floor space and easy installation

5、The air-cooled chiller adopts a top-out air design.

The working principle diagram of the water-cooled chiller is as follows:

Schematic diagram of the principle and flow of water-cooled chillers

The water-cooled chiller uses a shell and tube ( or tank with coil ) evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load of the water and cools the water to produce cold water. The heat is brought to the shell and tube condenser through the action of the compressor. The refrigerant exchanges heat with the water, so that the water absorbs the heat and then takes the heat out of the cooling tower through the water pipe to dissipate (water cooling)

Features of water-cooled chillers:

1. High-quality compressors are the heart of industrial chillers (brand-new original compressors from Europe, America and Japan, with built-in safety protection, low noise, power saving and durability).

2. The box-type evaporator has a built-in automatic water replenishment device, which saves the need for the expansion water tank in the engineering installation to facilitate installation and maintenance, and is suitable for special occasions such as large temperature difference and small flow.

3. The water-cooled condenser is made of the latest high-efficiency externally threaded copper pipe, with large heat dissipation and small size. Using the latest CAD/CAM processing technology, with CNC machining center to complete the production, compact structure, high reliability, beautiful appearance, high efficiency and energy saving.

4. Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor dryer filter and expansion valve, maintenance hand valve interface and other devices, to ensure the reliable and safe operation of the machine to facilitate maintenance and repair.

5. The multi functional operation panel of the industrial water chiller is equipped with ammeter, control system insurance, compressor switch button, water pump switch button, electronic temperature controller, various safety protection fault lights, unit start-up and operation indicator, simple operation and convenient use . Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor drying and expansion valve, maintenance hand valve interface and other devices, to ensure the reliable and safe operation of the machine, and facilitate maintenance and repair.
