Industrial chillers are the cooling equipment of choice of commercial, industrial, and institutional establishments. They are highly-advanced mechanical equipment that is designed to facilitate the easy exchange of heat from water to the refrigerant, the process of which occurs in a closed-loop type of system. The system’s refrigerant is then sent to a location wherein unwanted heat is forced into the atmosphere. The main component that defines how, for instance, the industrial water chiller will operate is the compression part of the refrigerant in its vapor phase.
Four common styles of the compression component are available; these are reciprocating compressors, centrifugal-styled compressors, rotary screw compressors and rotary scroll compressors. Each of these styles have its key benefits for selection, such as having ideal operation zone to match the process’s specified required cooling tonnage load, possessing moving parts, minimal noise, as well as having key components to throttle up or down in order to meet a demand shift.
What do these machines do?
Industrial chillers are created to lower existing temperatures of various machines, components, and processes; like robotic machinery; injection and blow-molding tools, welding machines, die-casting tools, cement processor, paper maker, power supplies; power generating stations; air cooling system; medical imaging equipment; and medicinal, chemical, beverage, and food production.
Industrial water chiller equipment is used to cool water to required levels. Whether a company desires comfort and convenience at the office for its employees, wants to keep its data server center from incidents of overheating, or wishes to perform any specialized industrial process, this water-cooling machine delivers the desired temperature to ensure the desired results.
Two chiller types
Absorption-type chillers utilize specific heat sources, like steam and natural gas, in order to perform a successful refrigeration cycle.
A commonly-used chiller is the refrigerant type, which is made up of four parts – evaporator, compressor, valve meter, and condenser. How does it work? The chiller collects heat, and later on, utilizes an evaporating heat exchanger to force the heat away. The refrigerant is then sent into the condenser where it will be compressed.
Two main types of refrigerant-type chillers
1. Air Condensers operate by using air as a cooling medium. This type of chiller is ideally used for operation outside the homes or buildings. These chillers reject heat that comes from the atmosphere via mechanical means, like the circulation of outside air via a special fan directly into the condenser. Air chillers do not need any cooling tower, unlike in the case of water chillers. These types of condenser cooled units do not require a cooling tower as is common with water cooled chillers. This is because the air is directly rejected into the atmosphere.
2. Water cooled chiller uses water as its main cooling medium. This device is usually installed in the interior areas of the house or building. It utilizes a cooling tower, or a body of water such as a river or pond that’s located near it in order to reject the heat of the water from the condenser.
