Planning / Implementation / Main components: |
SSP Kälteplaner AG
Johnson Controls Systems & Service GmbH |
|
Refrigerant: |
Ammonia (NH3) |
|
System start-up: |
June 2007 |
|
The refrigerated and frozen goods logistics company Frigosuisse supplemented its three existing deep-freeze warehouses in Möhlin, Switzerland with the addition of a fourth. To cool the new warehouse, the refrigeration specialists from the engineering firm SSP Kälteplaner AG designed a pumped ammonia system with Eco mode.
|
|
Demands: |
The new building, which has a volume of approximately 65,000 m³, was to be fitted with an economic, environmentally friendly system to maintain a temperature of -28°C in the deep-freeze warehouse, and of -10°C in the adjacent automatic picking hall.
|
|
Solution: |
SSP Kälteplaner AG was commissioned to draft a refrigeration system to meet these requirements. The engineering firm designed a plant which uses ammonia in a direct evaporation, multiple circulation system. Johnson Controls installed the system, which is charged with 2,100 kg of ammonia and has a peak performance of 540 kW, on the ground.
