Title: Sylvain Serge Douzet: Innovator in Heat Pump Technology
Introduction
Sylvain Serge Douzet is a notable inventor based in Saint Maurice de Beynost, France. He has made significant contributions to the field of heat pump technology, holding 2 patents that focus on innovative defrosting methodologies.
Latest Patents
One of his latest patents is a defrosting methodology for heat pump water heating systems. This invention involves circulating refrigerant through a vapor compression system that includes a compressor, a gas cooler, an expansion device, and an evaporator. When a sensor detects the formation of frozen water droplets on the evaporator, a valve opens to allow refrigerant from the compressor to bypass the gas cooler. This high-temperature refrigerant effectively melts the frost on the evaporator, enabling air to flow through it once again.
Another significant patent is the method and system for defrost control on reversible heat pumps. This control algorithm monitors the performance of a clean coil and creates a "frost factor" that indicates the level of frost build-up. When this factor approaches 100%, the refrigerant cycle is reversed to facilitate coil defrosting.
