A full-service hotel conditions 40,000 m3/h of guest-room and lobby air. EN159 used heat-pipe recovery to preheat and pre-cool make-up air.
The Challenge
The hotel needed balanced make-up air across seasons. Recovery had to be passive and quiet for guest areas.
Why Heat Pipe Air-to-Air Recovery
Heat pipes are silent, passive, and need no rotating drive, which suits guest-facing plant. For clean hotel air, plate or heat pipe both work; the owner chose heat pipe for zero-fan extra load and simple install.
The EN159 Solution
EN159 heat-pipe modules, 40,000 m3/h, make-up air recovered across seasons, 4 degree tilt, aluminium walls.
Measured Results
- Recovered heat: about 0.45 MW
- Conditioning energy cut by 29 percent
- No rotating-part noise in plant
- Estimated payback: 19 months
Compliance and Selection Notes
Heat-pipe recovery, separated streams, passive. Suitable for clean hotel air.
