Water source heat pumps are increasingly being used for residential
and commercial space heating. Typically, these heat pumps are capable
of both heating and cooling, and historically the design emphasis
has been on improving the units' cooling performance. Recently,
there has been more interest in improving the heating performance,
however,...
This thesis analyzes two systems that can meet low-grade heating
and/or cooling demands by operating in conjunction with thermal-electric
power plants. At the application site, one of the systems, HPS, has
water-to-air heat pumps that are connected to the supply and return
lines of a plant-to-user loop. During heating, the...
This thesis reports on an investigation of flow patterns in
shallow geothermal wells in Klamath Falls, Oregon, Although
wells have been extensively used in the area, the exact nature of
the flows in the wells has not been characterized.
Flow characterization is a principal object of this study.
Horizontal crossflows...
This thesis is concerned with designing and simulating waste
energy retrieval systems from large transformers to provide heating and
cooling of a control house. The transformer selected is Transformer
Bank One at the Ross Substation in the BPA system. The unit is an
ASEA 250 MVA transformer with forced oil,...
The low temperature geothermal resource at Klamath Falls,
Oregon is widely used for heating buildings. A common technique
for using this resource consists of a heat exchanger down in the
well inside a casing which extends the full length of the well.
Slots are cut in the casing to allow...
In this thesis, computer simulation and evaluation of solar cooling systems are presented. The simulations were conducted using the TRNSYS program, developed at the University of Wisconsin. The TRNSYS program was modified by the addition of new models for the solar collector with high fluid thermal capacity, the absorption cooler,...
The low temperature geothermal deposits in the Klamath
Falls area are commonly used for heating buildings. The
system often used to accomplish this consists of a heat
exchanger that extends the full length of the casing within
the well. This casing has slots cut in it to allow geothermal
water...
This thesis is concerned with simulating two forms of energy retrieval.
Standard computer programs are routinely used to simulate
such energy systems. However, the accuracy of these simulations is
not well documented. The main objective of the work presented here is
to evaluate the validity of this type of simulation...
The thermal energy storage requirements for a district heating
system utilizing geothermal energy is evaluated with respect to the
system design heating load and local climatic conditions. The
local climate pattern is represented by a series of events which
characterize the nature and sequence of the cold spells that can...
