NEW EXPANDED EDITION with color illustrations and spacious 8.5 x
8.5 format adds detailed descriptions of the components of the heat
pump, open loops systems and important decisions that the homeowner
must make.
Interest in residential geothermal systems has grown as more
people realize they can replace their fossil-fuel heating system
with one that is three to five times more efficient and doesn't
require a chimney to exhaust noxious fumes. Currently in the USA
there is a federal 30% tax credit that applies to the total
installation cost. These newer, safer systems provide heating as
well as cooling simply by transferring heat between the home and
the ground or a nearby body of water. Since this is a relatively
new technology, the number of experienced installers is limited,
but growing. Therefore, there is a burden on homeowners interested
in installing one of these systems to absorb as much information
about residential geothermal systems as possible. This book was
written specifically to meet that need as well as to help HVAC
professionals who are new to residential geothermal systems.
Readers will learn how heat pumps are able to extract heat from
relatively low temperature water circulating in ground loops and
raise it to a temperature high enough to heat a home. They will
also learn how to estimate the size of the heat pump required and
the ground loop size as well for straight 2-pipe, 4-pipe, 6-pipe
and Slinky loop configurations. This is important in order to
verify that the installer correctly sizes the system. An
incorrectly sized system will result in an unhappy homeowner. Both
horizontal and vertical loop systems, for GX and DX, are
covered.
Some of the technical issues that are addressed include: Loop
water flow rates and Reynolds Number, heat of extraction/rejection,
heating capacity, desuperheater setup, open-loop/closed-loop, SCW,
pond loops, DX, Manual-J, COP. The final chapter consists of a set
of flowcharts guiding the homeowner to ask the pertinent questions
needed for a successful installation.
