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.
