Project: 17 Story Building Refurbishes Heat Pump System
Solution: Create Temporary Condenser Water System.
A 17 story building utilize a heat pump system to cool 411 apartments. The basic system worked
by pumping in 85F sea water through an internal heat exchanger that feed condenser water to 411 apartments.
The existing system was due for a major refurbishment. During the summer months, the system began having
problems with the heat load. The building owner made the decision to begin the refurbishment project early.
Carrier Rental Systems (CRS) was called in to design a temporary system during the shutdown.
There were a few challenges that had to be addressed. First, timing was critical for the comfort of the
tenants. Careful coordination between CRS and the mechanical contractor was vital to the success of the
project. Second, space for a temporary system was limited. The owner could only afford to give up a 25'
by 60' area. Finally, the building did not have enough electrical power to supply the temporary system.
Having worked with a variety of systems in the past, CRS quickly designed a 1000 ton system that utilized
cooling towers, pumps and a generator to provide the condenser water for the 411 apartments. With
careful coordination, the entire process was completed in 12 hours and the building was up and running
again.
