Cons
Pro
 High Initial Cost
 Not suitable to maintain Humidity
(rather somehow only add Humidity)
 Need filtered water supply at high rate
(for1KW capacity need 1.27 l/hour)
Example 7TR (24.7KW)  32 l/hr Water
 Water Tank or Direct supply needed
 Expensive at lower Cooling Capacity
 No Heating Cuircuit
 Bulky
 Very High C.O.P
 Less operating Cost
 100% Eco-friendly
 Less maintenance
 High Reliability
 Modular Systems for higher capacities
 The hotter it is, the more effective it is.
