Abstract

A high-temperature geothermal-based heat pump prototype was designed and developed by a mechanical engineering capstone senior design team. It had to deliver water at a temperature above 140° F (60° C) using currently available technologies. Other requirements/specifications included: 3 ton (30 000 BTU/h, 8.8 kW) heating capacity; a coefficient of performance (COP) of 2 or more; saturated evaporator temperature of 25° F (-4° C); saturated condenser temperature of 120° F (49° C); and a maximum system operating pressure of 600 psia (4136 kPa), in order to meet safety standards. The heat pump was designed around the vapor-compression refrigeration cycle. This paper provides details about the design and development of the heat pump prototype, as well as the testing and validation of the unit.
