Free cooling ventilation is a process of using outside air to cool a building without the use of a mechanical refrigeration system. It is a very energy-efficient and environmentally friendly way to cool a building, especially in climates with cool winters and moderate summers. There are two main types of free cooling ventilation: direct and indirect. Direct free cooling ventilation: Direct free cooling ventilation systems pass outside air directly over the cooling coil of a chiller or air handling unit (AHU). This is the simplest and most efficient type of free cooling ventilation system, but it is only suitable for climates where the outside temperature is consistently cooler than the required chilled water temperature. Indirect free cooling ventilation: Indirect free cooling ventilation systems use a heat exchanger to transfer heat from the chilled water loop to the outside air. This type of free cooling ventilation system is more expensive than direct free cooling ventilation, but it can be used in a wider range of climates. Free cooling ventilation can be used in a wide range of buildings, including commercial buildings, industrial buildings, and data centers. Here are some of the benefits of using free cooling ventilation: Energy savings: Free cooling ventilation can save a significant amount of energy, especially in climates with cool winters and moderate summers. Reduced costs: Free cooling ventilation can help to reduce the costs of operating an HVAC system by eliminating the need for mechanical refrigeration. Environmental benefits: Free cooling ventilation can help to reduce the environmental impact of an HVAC system by eliminating the need for mechanical refrigeration. If you are considering using free cooling ventilation, it is important to consult with a qualified HVAC engineer to determine if it is right for your application. Here are some tips for using free cooling ventilation: Make sure the outside air is clean and free of pollutants. Use a filter to clean the outside air before it is used for free cooling. Use a heat exchanger to protect the chilled water loop from freezing. Use a control system to automatically switch between free cooling and mechanical refrigeration depending on the outside temperature. By following these tips, you can ensure that your free cooling ventilation system operates safely and efficiently.
