My name is Omar Lutfey. In 1996 I graduated from Colorado State University with Bachelor degrees in Mathematics and Computer Science. In 2002 I was hired at the UPS facility in Loveland, CO where I currently work as a Package Car Driver. Over the years I’ve become a bit of a heat pump enthusiast. I came across your company, Atmoszero, and I would like to apply for your Controls Engineer position. While my experience in the field of heat pumps isn’t in any way “traditional”, here are three projects I’ve developed on my own over the years.

Turbocharged Heat Pumps

While air conditioners can be quite efficient at transferring heat energy between two distinct areas, I believe the process could be improved by incorporating a turbocharger into the design. As refrigerant passes through the expansion valve and expands into a gas it turns a propeller. This force is then used to increase the pressure of the gas before it enters the compressor.

Simplified Heat Pump

While the design of heat pumps have largely been standardized, there is still potential to further simplify the equipment into a single rotating mechanism. Tubes filled with refrigerant are spun up causing the center to become a gas and the edges to compress into a liquid. Fan blades and insulation are incorporated to create a flow of heat perpendicular to the direction of the rotating device.

Whole House Geothermal Heating and Cooling

This system takes advantage of the large thermal mass of a home’s concrete basement floor to efficiently transfer energy throughout the year. It also benefits from incorporating all the building’s heating and cooling needs (HVAC, hot water heating, refrigerators, and freezers) into a single system. A final benefit is that it allows the compressor to run relatively independently from the immediate heating and cooling demands.
