What Are the Functions of a Water Chiller?
Water chillers are a type of commercial or industrial water refrigeration device or system. A chiller is designed to produce and circulate cold water in a closed system in order to maintain air temperatures for precision manufacturing.
Water chillers circulate as much as 400 tons of water and they can cool water to approximately 20°C (68°F). They are sometimes used as a replacement for an evaporative cooling tower and tend to be cost effective because they cycle water in a circuit rather than requiring a constant flow of city water.
Water chillers are used in production/manufacturing processes that use ozone generators, vacuum pumps, printing machines, lasers and more. Household application size water chillers are used to produce chilled drinking water or to regulate and cool water in aquariums. Water chillers are sometimes used in hydroponics to control the temperature of water going to plants.
Water chillers are sometimes called water coolers, particularly in consumer applications. Under the sink water chillers are designed to add additional filtration to drinking water. These filters typically remove organic chemicals and contaminants that may negatively affect the taste and clarity of drinking water. Well ventilated, properly installed, water chiller refrigeration units (out of direct sunlight) can produce as much as 10-15 cups of chilled water on demand. These can vary in degree of coldness from 20-32°C. These types of consumer water chillers are growing in popularity as an answer to buying pre-filtered bottled water while ensuring better water quality at the tap.
According to the United Nations Environment Programme, two-thirds of the planet will live in water-stressed conditions by 2025, if present consumption patterns continue. The use of water chillers impacts water availability and water and manufacturing costs both at the industrial levels and at the consumer level. As these stresses become more prominent in everyday life, it is likely that water chillers will become more common as water availability becomes more expensive.
Water chillers are machines that function behind the scenes of everyday life to assist in cooling foods and air, to maintain critical temperatures for plants, aquarium fish, manufacturing and more. They improve the quality of drinking water and reduce water flow waste, making them ecologically sound.
