Main research projects

 

-       Investigation on new refrigerants to replace CFCs.

The activity was both theoretical and experimental, aiming at the prediction of thermodynamic properties of refrigerants and of their performance in refrigerating systems, and at the measurement of the performance of small capacity refrigerating units (e.g. household refrigerators or plug-in commercial display cabinets) through experimental tests. In 1989 hydrocarbons and hydrocarbon blends were tested, which now are commonly used in domestic refrigerators.

 

-       Commercial refrigeration.

Setting up of a test room in compliance with the Standards for the measurement of the performance of commercial display cabinets.

 

-       Development of CFD finite-element codes for the solution of heat transfer problems.

Solution of benchmark problems, heat transfer improvement in heat exchangers and heat sinks.

 

-       Air curtains design in refrigerated display cabinets.

Thanks to the cooperation with main manufacturers of refrigerated cabinets, a thorough expertise on the operation of such systems was gained, which is witnessed by various well cited papers on air curtains and de-misting systems design. Promising solutions were investigated by means of CFD, for the improvement of the thermal performance of refrigerating units while reducing their energy consumption.

 

-       Heat recovery from refrigerating systems.

Strategies for heat recovery from refrigerating systems in favour of air conditioning (heating and/or cooling) plants, especially in shopping malls.

 

-       Modelling commercial refrigeration systems

Modelling commercial refrigeration systems as part of a more comprehensive model of shopping malls and their plants, aiming at the estimation of the energy requirement of the system as a whole, and at the identification of the most promising solutions for its reduction. Modelling of various plant configurations, with different natural refrigerants. Team leader of partner UNIUD in the FP7 Project “CommONEnergy: Re-Conceptualizing Shopping Malls From Consumerism To Energy Conservation”.

 

-       Investigation on growing conditions of corn salad in water saving floating systems.

Setting up of lab and field tests for the cultivation of corn salad at different water temperature controlled conditions in floating systems.

 

-       Modelling and design of air heating systems and water cooling systems in greenhouse

Temperature control in air and water for improving qualitatively and quantitatively the yield of soil-less cultivation of horticultural crops.

 

-       Design of equipments for process and sale of small quantity – high quality food.

This project was developed in the framework of MIERI project, a national research project funded by the Italian Ministry of Agriculture, for the realization of small scale equipment for food processing and sale especially devoted to small rural enterprises.

 

-       Design of particular equipments for combined freezing and treatment of food.

Design of refrigerating systems for quick freezing with simultaneous treatments of food.

 

-       Solutions to reduce emissions to atmosphere of VOC by biofiltration: system design and management.

Abatement of Volatile Organic Compounds (VOC) from industrial emissions (e.g. wood painting) by means of biofilter. Industrial scale prototype, design and management.
