1. Developing, testing and characterizing of suitable materials pair for cold van refrigeration (operating temperature <= 4°C).

2. Designing and engineering a retrofit HP-ACS system, to be easily assembled in cold van and with the scope to minimize system weight and volume by:

a. reducing MH mass requirements to achieve project specifics

b. optimizing auxiliaries;

c. selecting light materials

An appropriate design will allow to reach the cooling system SCP target of 50 W/kg, almost double than silica gel systems, and a SVCP (Specific Volume Cooling Power) of 130 W/l, much more compact of other heat-driven heat pumps. The entire system, including van air-heat exchanger and external air-heat exchanger, has to reach the target of 15 W/kg and 7.5 W/l, in line with compressordriven ACS. Moreover, the HP-ACS unit has to be easily installed in vans and to allow a easy and quick replacement of sorption materials at the end of them life (> 10.000 adsorption/desorption cycles, equal to more than 3 working years).

3. Implementation and testing of HP-ACS prototype on a refrigerated van, in conformity to the CEI EN regulation, to be benchmarked with presently van ACS systems.

4. Demonstrating the feasibility and reliability of the MHCS technology.

5. Evaluating the technical, economic and environmental impact of the HP-ACS technology in the cold transportation sector.
