US Patent No: 9200819

Optimizing the efficiency and energy usage of a geothermal multiple heat pump system

---

Abstract

---

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