Title: The Innovative Contributions of Roland L Roehrich
Introduction
Roland L Roehrich is a notable inventor based in Pittsburgh, PA, who has made significant advancements in the field of air conditioning and refrigeration systems. With a total of 12 patents to his name, his work has contributed to the efficiency and effectiveness of temperature control technologies.
Latest Patents
Roehrich's latest patents include innovative air conditioning and refrigeration systems that utilize cryogens for heating and cooling cycles. One of his notable inventions involves a refrigeration system that conditions air through a heat exchanger, employing heat pipes in its design. During the cooling cycle, a cryogen is circulated through the heat exchanger, while in the heating cycle, the flow of cryogen is halted, allowing heat to be transferred via the heat pipes. Another embodiment of his invention allows for the selection of evaporation temperatures of liquid cryogen based on the desired temperature of the conditioned space. This is achieved through selectable cryogen flow paths that provide varying pressures and evaporation temperatures. Additionally, vaporized cryogen drives a motor connected to a fan, which circulates air between the conditioned space and the heat exchanger.
