Hospital refurbishment reclaims exhaust heat

Thermal Technology, heat recovery, AHUs
This Thermal Technologies AHU serving a London hospital can transfer 500 kW of heat from exhaust air to supply air — and there are four of them.

Over 2 MW of heat can be recovered from exhaust air by four large air-handling units installed as part of ongoing refurbishment work at the Royal Free Hospital in London. Each of the four roof-mounted units supplied by thermal Technology can handle 27 m3/s and recover 501 kW of heat using an exhaust-air run-around coil.

The heat is supplied to matching coils in the refurbished ground-floor supply units.

Each AHU is about 6 m long, 4.7 m wide and 2.5 m high. To simplify lifting and transportation, each unit was supplied split into two equal sections for on-site assembly.

To protect the run-around coils from airborne dust, G4 bag filters were fitted. They have a far greater dust-holding capacity than panel filters, extending service intervals between filter changes.
