Free cooling or economizers save energy consumption by incorporating an extra fluid-to-air heat exchanger (fluid cooler) into a chiller. The warm fluid returning from the process is cooled by the air cooled fluid heat exchanger before it enters the chiller heat exchanger. When the outdoor air is cool enough, it can provide 100% of the […]

Free cooling systems with PCMs work by storing outdoor coolness (e.g., during the night) and release the coolness indoors during the day. The PCM can then be used during the day to absorb the heat from, e.g., passing air in a ventilation system or water in a pipe system, and stored as latent heat, to cool the building in the day when temperatures are higher and the need for …

Sep 10, 2007 0. 76F to 78F tower water will not get you any kind of free cooling. You'll need to have 42F to 45F in order to make it happen via PFHX or Trane's free cooling option. If it's going to be a problem with the other equipment using the tower, the equipment will need to be modified in order to make this happen.

This allows you to get free or very reduced ...

The goal of adding free cooling to any system is to maximize free-cooling tons, thus lowering the energy consumed. Traditional systems need to throttle back free cooling when operating in hybrid mode, the most important mode of operation. This is required to make sure the chiller can stay online to meet the building’s set point.
