Air Cooled Chiller Economizer

As the economizer detects the right level of outside air to bring in it utilizes internal dampers to control the amount of air that gets pulled in.

Air cooled chiller economizer.

When the exterior air levels are appropriate it uses the outside air to cool your building. Integrated chiller economizer technology is ideal for the process chiller replacement and design build markets. The air cooled chiller will come on once the evaporative cooler can no longer handle the load by itself. Economizer economizer in hvac as its name implies is a device that is used to save energy consumption by using the cool air from outside of a building to cool the internal space.

Instead of being re circulated and cooled the exhaust air from the servers is simply directed outside. Air side economizer to save energy in a building a building s hvac system can make use of an air side economizer to save energy in buildings by using cool outside air as a means of cooling the indoor space. In such a system outside air that is cooler than the air inside a refrigerated space is brought into that space and the same amount of warmer inside air is ducted outside. Evaporative cooler with air cooled chiller.

These integrated economizer systems can reduce process cooling energy costs a much as 60. Standard 90 1 does not allow the economizer control to be solely dictated by mixed air temperature. Legacy currently offers integrated economizer technology on forty air cooled and water cooled condenser chiller models. This leads to energy savings and extended chiller component life.

The integrated water side economizer wse option sometimes referred to as free cooling in the industry adds a fluid to air heat exchanger coil in series with the chiller refrigerant condenser coil. A variation on the water economizer for air cooled chillers is to use an evaporative cooler in series with the air cooled chiller. Cooler economizer a common form of refrigeration economizer is a walk in cooler economizer or outside air refrigeration system. It requires the economizer controller to use another variable such as outdoor dry bulb temperature to sequence operation with the mechanical cooling equipment.

An air side economizer see figure 1 below brings cool air from outdoors into a building and distributes it to the servers.
