The heat transfer coefficient of shell and tube evaporator is larger in liquid than in gas, and larger in flowing state than in static state.
Shell and tube evaporator of chiller has good heat transfer effect, compact structure, small area and convenient installation, so it is widely used. The refrigerant flows in the copper tube while the chilled water flows out.Throttled refrigerant liquid enters from the side of the evaporator and evaporates from the upper part.Large evaporators are usually equipped with special separation equipment.
When the shell-tube evaporator works, the shell is always full of liquid and carries out heat exchange in the form of liquid to liquid.Therefore, the heat transfer effect is good and the heat transfer coefficient is large.
In general, the heat transfer coefficient of evaporator is smaller than that of condenser, which is mainly due to the small heat transfer temperature difference.
HERO-TECH adopt enlarged evaporators and condensers, the unit can operate at temperatures of 45 ℃. We use high quality copper pipe for standard and adopt stainless steel pipeline for corrosive water.
We also have the water tank coil evaporator. The innovate evaporator-in-tank configuration ensure a steady water temperature offered, as the evaporator also cools the tank itself, reduces ambient heat gain, and increases the efficiency.
