DANFOS Tube-in-tube heat exchangerType HE for Air conditioning
Tube-in-tube heat exchanger type HE is used primarily for heat transfer between the liquid and suction lines of the refrigeration plant.
The purpose is to utilise the cooling e€ect, utilise which without a heat exchanger is otherwise lost to the ambient air via uninsulated suction lines.
In the heat exchanger, this e€ect is used to subcool the refrigerant liquid.
Features :
• High refrigeration capacity in evaporator
• Helps ensure vapour-free liquid ahead of the expansion valve
• HE 0.5-1.5: May be used in the following EX range: Category 3 (Zone 2)
• Maximum utilisation of the evaporator upon setting the thermostatic expansion valve for minimum superheat
• Helps prevent sweating and frosted-up suction lines
