Two Stage Vapor Compression Heat Pump with Solution Circuits: Catering to Simultaneous Chilling and Water Heating Needs
Abstract
The benefits of using a two stage
vapor compression heat pump with ammonia
water solution circuits (VCHSC) to
simultaneously provide chilled water for
air conditioning and hot water for various
uses are reviewed.
The performance results for a two
stage VCHSC are summarized. Experimental
results indicate that the two stage VCHSC
can achieve cooling coefficient of
performances as high as 1.04 while pumping
heat through a lift of 194°F (108°C).
Comparison is made with a system
consisting of a vapor compressor chiller
and a gas fired furnace. The basis for
comparison being primary energy usage,
energy cost and initial cost of the
systems.
Energy saving at various operating
conditions is estimated. In some cases,
energy saving could be as high as 31%.
Based on the national average energy
prices in 1991 and the projected prices
for 1995, suitable applications for the
two stage VCHSC have been identified.
