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.
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.
Shell and tube exchanger
Shell and tube heat exchangers exchange thermal energy from one fluid to another. Because it is characterised by low pressure loss, it is well-suited to air conditioning systems.
Solenoid valves are broadly used for controlling heat or cooling with ON/OFF consumers. An electrical current is turned into a magnetic field, which opens or closes the valve mechanically.
Speed controlled operation
Speed control by means of a frequency converter is without no doubt the most efficient way of adjusting booster pump performance exposed to variable flow requirements. The speed control method results in a new Q/H curve at reduced head and flow.
