Abstract

See full text

A method for operating a geothermal system is provided to optimize heat exchange between a geothermal loop and a heat pump load loop. The flow through the earth loop is adjusted to meet current thermal demand of a heat pump array, so as to reduce the electrical demand of the earth loop circulator when heat pump thermal demand is low. The speed of the earthloop circulator adjusts to meet the operating conditions of the heat pumps and earth loop, thereby permitting efficient laminar flow whenever possible, as long as thermal demand is met.
