Cycle, Heat Exchanger Design and Prototype Development of a Water Ammonia Heat Transformer

This project was carried over under contract DENG13-14 with the Energy department of Politecnico di Milano. Specifications for a 5 kW heat output heat transformer working with water ammonia with a source stream of water @ 50°C, a cooling water stream @ 5°C and a delivery hot water @ 70°C were determined in a joint… Continue reading Cycle, Heat Exchanger Design and Prototype Development of a Water Ammonia Heat Transformer

Cycle, Heat Exchanger Design and Proof of Concept Prototype Development and Testing of a Low Temperature Driven Air Cooled Water Ammonia Chiller

The aim of this work was to develop a proof of concept 3kW cooling unit of a patented dual lift three pressure low temperature driven air cooled water chiller. Full cycle simulation has preceded the specific design and development of the 9 heat exchangers that make up the prototype. Extensive testing and experimental data analysis… Continue reading Cycle, Heat Exchanger Design and Proof of Concept Prototype Development and Testing of a Low Temperature Driven Air Cooled Water Ammonia Chiller

Cycle and Heat Exchanger Development of a 18 kW Heating Capacity Residential Gas Absorption Heat Pump

This work was part of an industrial project conducted by Robur SpA to develop a 18 kW heating capacity residential gas absorption heat pump. The task was to model the absorption cycle to be able to deliver high efficiencies down to 30% partial load and to design the entire unit to fit within a set… Continue reading Cycle and Heat Exchanger Development of a 18 kW Heating Capacity Residential Gas Absorption Heat Pump
