AiCARR Journal, the periodical dedicated to professionals for HVAC systems field, has published an article in the number 31 of April 2015 related to the issues about the integration of air conditioning systems with cold storage of food.

The need to find cost-effective energy solutions in the field of food distribution depends on the wide energy consumption required by this type of system, the most energy-intensive one among those installed in a store.

The article of the newspaper cites an example of installation of a multi-pipe system provided by Thermocold for the project "Coop Carpi" in collaboration with INRES (National Institute for Economic and Social Research), the national consortium that designs Coop’s sales buildings. The multipurpose unit 4 pipe Quattro Prozone 2310 ZMA was chosen as the most appropriate solution to meet the typical requirements of the food refrigeration systems, as it is able to guarantee high COP values between 4.4 and 5.

The solution proposed by INRES is the innovative technology 4 pipes unit, characterized by the ability to recover the available heat of the plant optimizing the overall system performances. The heat generated from the cold storage plant is used as a fundamental source of energy without the use of complex plant systems or additional heat generators.

In winter the condensation heat produced by the food refrigeration system is recycled with an air-to-water exchanger and it’s used as the cold source of the multi-pipe unit. In summer, the unit operates as a normal air cooled chiller. The exceeding cooling capacity generated by the unit is used for the sub cooling of the refrigeration food system by increasing the performances. The wasted heat in summer can be recovered by the post-heating coil of the AHU serving the sale area.

Thermocold is pleased to be among the first companies in Italy to provide a multi-pipe unit to the service of a food refrigeration plant. The solution devised by INRES and realized by Thermocold presents several advantages compared to other plant solutions such as excellent energy performance, continuity of operation due to the physical separation of the two autonomous plants together with the capability of a hydronic unit to be flexible to any layout changes of the building.
