Outdoor industrial chillers are refrigeration equipment designed for industrial environments and installed outdoors. Their core function is to continuously provide low-temperature cooling water (or other media) for industrial production processes or equipment through refrigeration cycles to control temperature, dissipate heat or maintain process stability. The following is a brief introduction to outdoor industrial chillers:
Operating principle
Refrigerant cycle: The liquid refrigerant in the evaporator absorbs the heat in the water and evaporates into gas, which is sucked in and compressed by the compressor. The pressure and temperature rise. The gaseous refrigerant releases heat and condenses into liquid in the condenser (air-cooled/water-cooled). After throttling by the expansion valve, it becomes low-temperature and low-pressure refrigerant and enters the evaporator to complete the cycle.
Water cycle: The water pump draws water from the water tank to the equipment to be cooled. The chilled water takes away the heat and the temperature rises before returning to the chilled water tank.
Product Type
Air-cooled: Generally, it is an integrated machine, but it can also be made into a split type. The shell and tube evaporator is used to exchange heat between water and refrigerant. The refrigerant absorbs the water heat load to cool the water. The compressor brings the heat to the finned condenser, and the heat is dissipated into the air by the cooling fan. It does not need to be equipped with a cooling water tower, and is suitable for environments with poor water quality.
Water-cooled: Shell and tube evaporator is used to exchange heat between water and refrigerant. The refrigerant absorbs the heat load of water to cool the water. The heat is brought to the shell and tube condenser through the compressor. The refrigerant and water exchange heat. After the water absorbs the heat, it is taken out through the water pipe to the external cooling tower for dissipation. Water-cooled chillers have high heat dissipation efficiency, but they need to be equipped with cooling water towers.
Product feature
Adapt to outdoor environment: It has good protection performance, such as waterproof, sun-proof, dust-proof and other designs, and can operate stably under adverse weather conditions.
Good heat dissipation effect: It is usually equipped with an efficient radiator and fan system, which can quickly dissipate heat to ensure the normal operation of the machine and stable cooling effect.
Easy to install: No special indoor machine room is required, and it can be directly installed in outdoor open space or rooftops, saving indoor space.
Application Areas
Industrial production: Cooling of production equipment in industries such as plastics processing, metal processing, chemicals, and pharmaceuticals, such as injection molding machines, extruders, die-casting machines, reactors, etc., can ensure the normal operation of equipment in high temperature environments and improve product quality and production efficiency.
Food and beverage industry: Used in cooling and freezing links in food processing and beverage production, such as milk cooling, fermentation cooling in beer brewing, ice cream production, etc., which helps to ensure food quality and extend shelf life.
