The goal of our Capstone Project is to create a heat pump demonstration/test unit that simulates the climate of Northern Maine during the winter. With this demonstration unit we hope to convey to the public how a heat pump unit works, how the coefficient of performance and cost per Btu vary with the temperature difference of the unit, and how using a heat pump with an alternative heating source can save money over conventional oil heating. We will convey this message to the public by using an enclosure and fan control system to maintain a constant desired temperature around the outdoor unit of the heat pump while the heat pump is running.  When the heat pump is running, the real time coefficient of performance as well as the real time cost per Btu of the heat pump will be calculated through a data acquisition system. This information, as well as the cost / Btu of oil heat, will then be displayed to the public on a display monitor on the front of the unit.  This will convey to the public how a heat pump can sustain most Northern Maine households and how a heat pump can save money over conventional oil heating.
