Roof tank systems
Roof tanks are fresh water tanks, placed atop high-rise buildings. Roof tank installations are used in water supply applications mainly due to unstable water mains and unstable power supply.
The saturation point is the point at which air is unable to absorb more water. Saturation point can also be referred to as dew point. It can also be stated that a saturated liquid, such as water or a saturated vapour, contains the maximum amount of heat energy without boiling or condensing.
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.
