MPHE gives up to 20% refrigerant savings as compared to a tradinal BPHE
MPHE is also more resiliant to impurities in the water as compared to BPHE
Capacities from 1TR to 30TR
Design Condition: with R22 SST: 2'c, SDT: 50'c, Tsh: 5K Tsc:5K Water in 12'c & Out 7'c
Tube-in-Tube Heat Exchangers, type HE
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 effect, utilise which without a heat exchanger is otherwise lost to the ambient air via uninsulated suction lines
In the heat exchanger, this effect is used to subcool the refrigerant liquid
Helps ensure vapour-free liquid ahead of the expansion valve
Helps prevent sweating and frosted-up suction lines
