PDM Solar is developing vapor compression air conditioners and heat pumps that are powered by heat rather than by electricity. The heat to power our technology can be provided by solar thermal, waste heat from data centers, or from the exhaust of trucks and buses. PDM Solar's patent protected THERMAL TRANSFORMER™ heat driven vapor compression technology is versatile enough to provide the foundation for products to meet many market opportunities. Market Opportunities include solar air conditioners, data center cooling, waste heat from industrial and commercial processes, truck and bus cooling, ultra high efficiency gas furnaces, geothermal heat pumps, and net-zero buildings. THERMAL TRANSFORMER™ Definition THER•MAL TRANS•FORM•ER noun: 1. a single-cylinder heat engine coupled to a single-cylinder compressor/expander using a hydraulic connecting rod. 2. a device used to provide heating or air conditioning that is powered by heat energy.
