Title: Joseph Albert Stocker: Innovator in Heat Pump Water Heater Technology

Introduction

Joseph Albert Stocker is an inventor based in Dover, NH (US). He currently works at Thermo Fisher Scientific GmbH. Although he has not been granted any patents, he is actively involved in developing innovative technologies related to heat pump water heaters.

Latest Patent Applications

Joseph's latest patent applications include two significant innovations. The first application is titled "Obstruction Detection for a Heat Pump Water Heater System." This system features a compressor that compresses coolant and an evaporator with a fan that facilitates air flow. It includes a first heat exchanger that transfers heat between the coolant and water. The system is equipped with a temperature sensor to detect ambient air temperature and a pressure sensor to monitor air pressure at the evaporator. Control circuitry communicates with these sensors to identify and classify obstructions based on temperature readings.

The second application is "Heat Pump Water Heater with Compressor Modulation to Extend Low Ambient Operation." This system also includes a compressor and an evaporator, along with a heat exchanger that heats water using heated refrigerant from the compressor. A controller adjusts the compressor's speed to maintain pressure, allowing the water heater to operate efficiently at lower ambient temperatures. If necessary, a defrost cycle can be initiated to ensure optimal performance.

Conclusion

Joseph Albert Stocker is making strides in the field of heat pump water heater technology through his innovative patent applications. His work demonstrates a commitment to enhancing energy efficiency and functionality in water heating systems.
