Solution: The refrigerant should be discharged according to the suction and discharge ...

Energy Saving Fact Sheet Chillers - NC

High-efficiency chillers can produce chilled water using less than 0.50 kW per ton of cooling capac-ity. A refrigeration system must also reject the heat that it removes using a cooling tower for water cooling the condenser (most efficient) or using fans for air cooling the hot refrigerant of the condenser coil. Chiller Performance Ratings

Selection Criteria For Water Chiller Condensers

Industrial water chillers are available with a choice of two types of refrigerant condensers: Water-Cooled or Air-Cooled. It is important to choose the right type of condensing medium for the environment the water chiller will operate in.

How Does a Chiller Work? Industrial ... - water chillers

Jul 09, 2019 1. Phase Change. A liquid coolant undergoes a phase change into a gas when heated, and when the gaseous coolant is supercooled, it condenses back into a liquid. 2. Heat Flow. Heat energy always flows from an area of high concentration to an area of lower concentration. 3. Boiling Point. Reducing the pressure over a liquid decreases its boiling ...

How HVAC Chillers Work - Refrigeration School Inc. (RSI)

Mar 01, 2016 The Cooling Cycle of an HVAC Chiller. Compressor to Condenser: The compressor sends hot refrigerant gas to the condenser, where the refrigerant’s heat is transferred to the cold water outside the component. As it cools, the refrigerant turns into a liquid. Condenser to Metering Device: The metering device limits the flow of the liquid ...

Water as a Refrigerant - Efficient Energy

Water is also frequently used in adsorption processes, especially because of its outstanding evaporation enthalpy and environmental friendliness. The use of water for stream blasting refrigeration, by contrast, is a niche application. Until now, water as a refrigerant in compression chillers has not been economically viable.

The Basics of Chillers - HVAC Investigators

Water-cooled chillers use water to surround the refrigerant pipes and draw in the heat (path shown in red). The water is then pumped into a cooling tower to release the heat. After condensing, the refrigerant goes through an expansion valve to reduce pressure (and temperature) before returning to the evaporator, where the process begins again.
