This Navigant Research report analyzes the global market opportunity for energy-efficient commercial HVAC systems, including unitary systems, heat pumps, furnaces, boilers, variable refrigerant flow (VRF) systems, chillers, and geothermal heat pumps
Since geothermal heat pumps
are so cost-effective, the customer's heating bills remain relatively low even though they are operating throughout the winter months.
Tenders are invited for Purchasing A Mobile Laboratory and Geothermal Heat Pumps
Numerical Simulation Software - Lot 1 and A Mobile Laboratory for the Study of Energy Performance and Environmental Quality and Pollutant Dispersion Simulation Software - Lot 2
Specifically, Energy Star defines the geothermal heat pump
components to include heat exchangers, compressors, pump models, hydronic space conditioning distribution systems, temperature controls, and thermal storage tanks (see "Energy Star Program Requirements, Product Specification for Geothermal Heat Pumps
: Eligibility Criteria," Version 3.
However, the implementation of geothermal heat pumps
in locations with relatively low heating requirements might not be economically feasible, since the capital costs of these systems are significantly higher than air-to-air heat pump systems.
There will be green area, including on roofs, geothermal heat pumps
, heating with solar energy and a lot of innovative features," he stressed.
This includes spending on the construction of geothermal power plants used to produce electricity, and spending on the installation of geothermal heat pumps
, district heating systems, and the other applications that make up the direct use geothermal submarket.
Topics discussed include types of geothermal heat pumps
, ground loops, efficiency and load calculations, tax credits and rebates and calculating the net value or "payback" of the systems.
a leading provider of geothermal energy harvesting solutions, has announced a geothermal system testing site, comprised of three separate geothermal heat pumps
Geothermal heat pumps
(profiled in the January/February 2009 edition of E) rely on the constant temperature underground to save energy, but the up-front cost of drilling can run into the tens of thousands of dollars.
The ESPC replaced the old central steam plant with a combination of distributed boilers and geothermal heat pumps
Geothermal heat pumps
can also provide space heating and cooling where no geothermal resource is present by using the earth as a heat source and/or sink.
