A design was created to provide a novel passive control that operates a passive solar heating and cooling system for residential homes in Wyoming. Mathematical models were developed to determine the pertinent parameters of a control that will allow air to flow in or out of a house for heating or cooling purposes. The control was designed to be implemented in existing passive solar collector systems. It is composed of bimetallic spiral coils, ideally made of ASTM B388 TM2 – an alloy composed of 72% manganese, 18% copper, and 10% nickel for the high expansion component while the low expansion component is composed of 36% nickel and 64% iron, an aluminum shaft, and a damper made from ultra-high-molecular-weight (UHMW) plastic. The control has the ability to be adjusted by a user friendly dial similar to existing thermostat dials. The mathematical models for the control show a maximum deflection of 42 degrees of rotation relative to a coupled 160 degree temperature change within the collector and a 50 degree temperature change within the room that would allow for either heating or cooling. The control design provides an effective way to passively operate a passive solar heating and cooling system.
