Title: The Innovative Contributions of Dennis R Pandy

Introduction

Dennis R Pandy is a notable inventor based in South Windsor, CT (US), recognized for his contributions to the field of heat pump technology and hydrocarbon fuel combustion. With a total of 2 patents, Pandy has made significant advancements that enhance efficiency and reduce pollutants in these systems.

Latest Patents

One of Pandy's latest patents is titled "Vapor separation of variable capacity heat pump refrigerant." This innovative heat pump system features a separate outdoor coil mounted below the primary outdoor coil, connected in parallel by valves. During startup in heating mode, the inlet of the auxiliary coil is closed while the outlet is opened, allowing the compressor vacuum to boil off the more volatile, high-pressure components, thus filling the system. The outlet valve is then closed, trapping the low-pressure component in the auxiliary coil. A second embodiment utilizes an accumulator to assist the auxiliary coil in vacuum separation of the refrigerant blend.

Another significant patent is the "Method and system for combusting hydrocarbon fuels with low pollutant." This method involves mixing hydrocarbon fuel with a first air stream to create a fuel/air mixture with an equivalence ratio greater than 1. The fuel is partially oxidized by contacting it with an oxidation catalyst, generating heat and a partial oxidation product stream. This stream is then mixed with a second air stream and completely combusted in a main combustor, minimizing the formation of thermal NO.sub.x and resulting in an effluent gas stream with reduced pollutants.
