System start-up |
2002 |
Frigopol, a manufacturer of refrigerant condensers, chillers and complete refrigeration systems, equipped its new office building in Frauental, Austria with air conditioning, relying on R 723, a new natural refrigerant. |
|
Demands |
In 2001, the company built a new plant including production and office facilities. All offices were to be air-conditioned to ensure a pleasant "working climate." Economic efficiency and environmental friendliness were the top priorities. |
Solution |
The heart of the refrigeration plant, which runs on the natural refrigerant compound R 723, is a dual-circuit liquid refrigeration unit. At an evaporating temperature of 0 degree Celsius and a condensation temperature of 45 degrees Celsius, its refrigeration capacity is around 60 kilowatts. The facility consists of two separating hood compressors, each with a plate heat exchanger and an air-cooled condenser. The design of the installation largely corresponds to that of a conventional HFC refrigeration plant. |

Special features / Comments |
The new natural refrigerant R 723 combines the energy advantages of ammonia with the straightforward facility design of oil-soluble refrigerants. R 723 has a large volumetric refrigerating capacity and accordingly high coefficients of performance. |
