Add chemical scale-inhibitor, this not only results in the increase of cost, can also accelerate the corrosion leakage for evaporating cold heat exchanger surface, influence machine
Group operation stability.
Moreover, evaporation cold group is in a heating mode, it is " cold to be discharged in saturated steam in cooling water absorption air
For solidifying heat " as heat source, heat exchange efficiency is very low, and causing evaporation cold group, energy consumption is higher in a heating mode.Moreover, working as environment
When temperature is lower than 0 DEG C, cool water shower to evaporation cold heat exchanger surface will be frozen, to can not generate just with cooling medium
Normal heat exchange causes evaporation cold group that can not heat in area of the environment temperature lower than 0 DEG C.
In consideration of it, air-cooled unit is in terms of heating by environment temperature currently, heat pump unit is usually air-cooled unit in industry
Influence is smaller, but energy consumption for cooling is big.
