Greenheck’s new Model PVe heat recovery unit is designed to recover up to 60% of the sensible energy in the exhaust airstream and return it to the supply air. The cross-flow plate exchanger unit uses an aluminum core (plate) to recover only sensible energy, and has very low leakage and no moving parts. Features include stainless steel drain pans, easy to remove hinged doors, belt drive blowers with adjustable pulleys, a pitched roof, and integral lifting points and lift locations. Model PVe is ideal for applications that involve dirtier air such as garage exhaust, welding shops/facilities and areas with drier climates. Performance ranges from 1,000 to 6,000 cfm.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
