Abstract: An air conditioning system for use in an over-the-road or off road vehicle is provided that provides a method of operation during both engine on and engine off conditions. The method operates the air conditioning system at one capacity when the engine is running, and at a second capacity when the engine is not running. The selection of these capacities is based on the power capacity of the source of electric power from which the air conditioning system is operated. When a storage battery is used to power the air conditioning system during engine off conditions, the second capacity is lower than the capacity at which the system is operated when the engine is running.

Abstract: 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. Specifically, if flow in the earth loop transitions from turbulent to laminar, this method insures that the current thermal demand of the heat pumps is met, and if not, increases the earth loop circulator speed to meet current thermal demand, otherwise maintaining laminar flow.
