Chillers Geoclima with HFO for food industry
Geoclima’s expertise in the design of HVAC systems for food storage has been recently employed in Spain in two plants for cooling and conservation of food.
Both project use HFO-1234ze refrigerant, which is a very good solution in this kind of application as HFOs are highly efficient, which adds to its minimal warming profile with reduced indirect emissions, and has the potential to deliver significant cost savings.
UVAS DOCE – REFRIGERATION AND CONSERVATION OF GRAPE
For one of the leading European companies growing and exporting grape, Uvas Doce S.L., Geoclima has co-operated in the replacement of the cooling plant of the facility in Monforte del Cid, Alicante. In this plant the harvested grapes are subjected to “air cooling” by means of which high-pressure cold air captures and removes heat from the product, cooling it. Every hour, 10 tons of grapes are processed. For this facility Geoclima has designed with the customer Frimavi two 300 kW (85 ton) GHA units with HFO1234ze for a total power of 600 kW (170 ton) and a maximum Cooling COP of 2.4/2.6 (W/W)*
*Cooling kW/TonR = 1.4/1.3 – Cooling EER BTU/Wh = 8.2/8.8
ZANEMI – REFRIGERATION AND CONSERVATION OF VEGETABLES
For the renovation of a vegetable storage facility of the Spanish company Zanemi in Villena (Alicante), Geoclima, together with the customer Frimavi, has designed and installed the new refrigeration plant. This is a process cooling installation for food preservation through a hydro-cooling process: freshly harvested vegetables enter a cooling tunnel at a temperature of about 25 °C (77 °F) and after a cooling process in which they get in contact with freezing water, vegetables come out at a temperature of 2 °C (35.6 °F). After the cooling process, vegetables are stored at a temperature of 1 °C (33.8 °F). The plant processes 10 tons of vegetables per hour. The solution provided by Geoclima consists of a 200 kW (57 ton) GHA unit with heat recovery, HFO-1234ze refrigerant and Cooling COP between 2.7 and 2.9 (W/W)*
*Cooling kW/TonR = 1.3/1.2 – Cooling EER BTU/Wh = 9.2/9.8
