Comparing GSHP and ASHP Performance Ratings
Dan Ellis
Do ground-water and ground-source heat pumps still make sense given the advent
of 19 SEER air-source heat pumps and the impending minimum efficiency
level of 13 SEER for these products? This presentation will explain how these
ratings are determined and offer methods for comparing the efficiency of these
products, both under idealized rating conditions and in “real world” applications.
CPTherm-G - A New Fluid for Closed Loop Geothermal
Systems
Dean Hamil
CPTherm-G is an aqueous heat transfer fluid for closed loop geothermal systems.
The product has undergone extensive lab testing for corrosion and was
also run in a laboratory closed loop system for over 5000 hours using commercial
components. To date, results have been encouraging. CPTherm-G
was developed to address specific problems associated with currently used
fluids such as flammability with methanol and low temperature viscosity issues
with glycol. Robust anti-corrosives and a buffer system are included to
counter corrosion. The improved heat transfer properties of the fluid can lead
to reduction in loop size which can decrease up-front costs and also reduce
operational costs.
Optimization Study of a Hybrid Geothermal Heat Pump
System
John Shonder, Oak Ridge National Laboratory
The lack of consensus on the design and control of hybrid geothermal systems
has limited their use. A set of hybrid configurations and control schemes was
identified and implemented into a simulation model by ORNL. Shonder will
discuss the study’s results, compare the systems and control strategies, describe
the optimized system, and provide some limited sensitivity analysis of
the variables that affect the system design.
