CHILLER
A chiller (cooling water circulation device) is a general term for a device that controls the temperature by circulating a liquid such as water or heat medium as a cooling liquid whose temperature was adjusted by the refrigerant cycle. In addition to maintaining the temperature of various industrial devices and laboratory instruments, equipment and apparatuses at a constant level, it is also used for air conditioning in buildings and factories. It is referred to as a “chiller” because it is often used for cooling.
Types of Chiller
Air-cooled chiller
This is a type of system that sends wind to the heat exchanger and cools the refrigerant with air. There is a built-in fan motor inside the chiller, and it is easy to install, but because exhaust heat is generated in the room, exhaust equipment may be required in tight spaces. The gas compressed with the freezer (compressor) is cooled by a condenser (radiator) and liquefied. It is comprised of a refrigerant gas cycle and a circulating water cycle, and refrigerant gas is used as a heat medium to cool the circulating water.
Water-cooled chiller
This is a type of system that uses a cooling tower to cool water. Cooling water for the refrigerator is required, but it offers advantages such as excellent cooling efficiency and does not generate exhaust heat in the room.
