Water Heat
Exchanger
Minimum water volume in the system
(Formula)
The minimum water content per unit should be calculated with a certain approximation using this simplified formula:
Q= 35.83 X ( P(kW) / ? T(°C ) ) X ( 1/ N ) where : Q = minimum water content per unit expressed in litres P = minimum
cooling capacity of the unit expressed in kW ?T = evaporator entering / leaving water temperature difference
expressed in °C N = Number of compressors For more accurate determination of quantity of water, it is advisable to
contact the designer of the plant.
Air heat
exchanger
Type Lanced fins – internally spiral wound tubes
