The features of a chiller will vary based on the type of unit you have. A vapor compression chiller has a compressor, evaporator, condenser, and metering device. An absorption chiller will use a heat source instead of a compressor, and they use two fluids, including a refrigerant and an absorbent. They will both provide the same end result – cooler air or cooled equipment. They simply have slightly different components to achieve the same task. Some may have additional features such as emergency alarms and casters for easier movement.
How chillers work
Both of the techniques rely on the same principles. First, the liquid is heated and it vaporizes into a gas. Then, it cools and condenses into a liquid. By lowering the pressure above the liquid, it lowers the boiling point. If the pressure is raised, it raises the boiling point. It then makes it possible to chill the air, because of the way the heat flows in the system. most of the time, when used in an HVAC system, the water that is cooler goes into coils or heat exchangers in air handling units. The coils transfer the heat from the air to the water, and this can help to cool and dehumidify the air stream.
A chiller is a type of machine that will remove heat from a liquid through one of two different techniques – vapor compression or an absorption refrigeration cycle. The liquid can then pass through a heat exchanger, which makes it possible to cool air or to cool equipment.
