17 Story Building Refurbishes Heat Pump System

Project.

17-story building refurbishes heat pump system.

Solution.

Carrier Rental Systems (CRS) created a temporary condensor water system.

Application.

A 17-story building utilizes a heat pump system to cool 411 apartments. The basic system works by pumping in 85 degree F sea water through an internal heat exchanger that fed the condenser water to the 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. 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. Below are sample pictures of the project:
