SWEP Inc.: Heat Pump Heat Exchanger
June 4, 2012
The B26 AsyMatrix® brazed plate heat exchanger (BPHE) is designed for heat pumps. It is an asymmetric condenser for ground-source and reversible air-to-water heat pumps with a wide capacity range between 5-40 kW. The asymmetric plate geometry allows the unit to deliver superior performance with a very low water pressure drop to optimize system efficiency. According to the manufacturer, the B26 is 30 percent shorter than symmetric heat exchangers in the same capacity range and offers a reduction in refrigerant hold-up volume up to 50 percent. The AsyMatrix plate pattern improves heat transfer while decreasing water pressure drop and refrigerant charge, said the company. The product is approved for pressures up to 45 bar (650 psi), so it can be used with the majority of current high-pressure refrigerants.
