Parametric sensitivity study for solar-assisted heat-pump systems. Final report

PDF Version Also Available for Download.

Description

A sensitivity study is performed of the engineering and economic parameters affecting life-cycle costs for solar-assisted heat pump systems. The change in energy usage resulting from each engineering parameter varied has been developed from computer simulations, and is compared with results from a stand-alone heat pump system. Three geographical locations are considered: Washington, DC, Fort Worth, TX, and Madison, WI. Results indicate that most engineering changes to the systems studied do not provide significant energy savings. The most promising parameters to vary are the solar collector parameters tau ..cap alpha.. and U/sub L/ the heat pump capactiy at design point, ... continued below

Description

A sensitivity study is performed of the engineering and economic parameters affecting life-cycle costs for solar-assisted heat pump systems. The change in energy usage resulting from each engineering parameter varied has been developed from computer simulations, and is compared with results from a stand-alone heat pump system. Three geographical locations are considered: Washington, DC, Fort Worth, TX, and Madison, WI. Results indicate that most engineering changes to the systems studied do not provide significant energy savings. The most promising parameters to vary are the solar collector parameters tau ..cap alpha.. and U/sub L/ the heat pump capactiy at design point, and the minimum utilizable evaporator temperature. Costs associated with each change are estimated, and life-cycle costs computed for both engineering parameters and economic variations in interest rate, discount rate, tax credits, fuel unit costs and fuel inflation rates. Results indicate that none of the feasible engineering changes for the system configuration studied will make these systems economically competitive with the stand-alone heat pump without a considerable tax credit.
