Water-to-Air Heat Pump Performance with Lakewater
Abstract
The performance of water-to-air heat
pumps using lakewater as the heat source
and sink has been investigated. Direct
cooling with deep lakewater has also been
considered. Although the emphasis of the
work was with southern lakes, many results
also apply to colder climates. During the
project several open loop systems, one
closed loop plastic coil system, and one
copper coil system were monitored. Many
thermal surveys of lakes were located and
performed. Computer codes were developed
to determine closed loop coil length and
lake thermal response to assist in design
guideline development. This paper also
includes recommendations concerning heat
pump selection, pumping systems, piping
arrangements and lake size/depth
characteristics.
