What is indirect free cooling?
Systemair’s Indirect Free Cooling units (25 kW-300 kW) are specially designed for energy-efficient cooling of IT equipment in data centre facilities. Most time of the year the units work with only outdoor air to cool by using a high-efficient air-to-air heat exchanger.
What is free cooling system?
A free cooling system reduces energy use by using a fluid cooler or cooling tower to cool the process fluid in place of a chiller. It can use either a dynamic or static set point and can be isolated from the process fluid circuit with a heat exchanger, or can be in a common fluid circuit with the process fluid.
What are the benefits of free cooling?
Thanks to the ‘free’ cold conditioning, the system guarantees a considerable saving in energy consumption. The reason behind this is simple: in those places where the ambient air is colder than the one in shelters or equipment rooms, the system works more hours and therefore, saves energy.
What is the way of achieving water side free cooling?
There are many ways to achieve free cooling with different types of systems. For water-cooled systems it is common to use a large plate & frame heat exchanger to transfer cooling between the cooling tower loop (when temperatures are favorably low) and the chilled water loop.
Where can free cooling be used?
Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term.
How do water side economizers work?
Description. For data centers with water- or air-cooled chilled water plants, a water-side economizer uses the evaporative cooling capacity of a cooling tower to produce chilled water and can be used instead of the chiller during the winter months. This can reduce the risk of data center down time.
What means chiller free?
Chiller-free properties mean that you as a tenant are not paying for air conditioning usage. If you are renting in an area with district cooling, you can still have chiller-free as a benefit, because this is a choice that is made by the landlord.
What is data center cooling?
Through effective containment, data centers can reduce the risk of hot and cold air mixing. Free cooling can also help to improve data center energy efficiency. There are a number of forms of free cooling, including thermal reservoirs, low-temperature ambient air and evaporating water.
