Profitability of ago congelo
The profitability of the ammonia-water absorption chiller can only be calculated by taking into consideration the following criteria. An individual analysis of the overall system is always necessary.
Costs for refrigeration plants depend on design parameters, such as:
- Refrigerating capacity
- Heating medium temperature (depends on the temperature of the refrigerant)
- Temperature of the refrigerant
- Re-cooling temperature or cooling water temperature
- Rectification efforts, etc.
The profitability of a NH3 absorption chiller can only be calculated taking into consideration:
- the exact conditions of the location
- the current operating costs (such as gas price, water costs, sewage costs and electricity costs)
- the heat price, electricity credits in case of CHP waste heat (cogeneration bonus)
- the costs of saved electricity and operating costs
- the costs saved due to the lower electrical connection power
- the determination of the reference plant
- the necessity of redundancy, etc.
