owner of this project currently owns a hotel in downtown Monterrey,
providing him with extensive operational experience. His main objectives
for the HVAC system were to provide high reliability, high energy
efficiency, and ease of service.
design reflected those requirements by using multi-cell cooling
towers and pumps with variable frequency drives to closely track
the actual building load while minimizing the energy consumption.
guest room heat pumps are activated via the room card access system
so only those occupied guest rooms are running. Any unit for an
unoccupied room is shut off and the condenser water flow is shut
off by its internal solenoid valve. The owner also purchased extra
unit modules in the event of failure. Any guest room unit module
can be replaced in a matter of minutes, avoiding having to keep
the room out of service for any extended length of time.
