Coolant can be divided into primary coolant and secondary coolant. A secondary coolant is generally non-toxic in small amounts, though larger amounts must be disposed of appropriately.
Sensible cooling load
Sensible cooling load is a measurement of the amount of energy that must be removed from, for example, the air inside a building, in order to maintain a certain temperature, regardless of the temperature outside. Cooling load must be taken into account, when calculating the capacity of a cooling system.
