The planning process should include the following steps:
- identify all equipment with HCFCs, i.e. identify each individual system that uses HCFCs, including small air conditioning or refrigeration systems.
- Establish relevant information for each plant. Essential data include: - quantity of refrigerant in the system; - historical records of amount of refrigerant used to top up the system (this gives an indication of leakage rates); - age of the system; estimate of original design life of the system; - cooling load details (e.g. size, temperature level and variability of each cooling load); - plant design details (e.g. compressor types and size, evaporator and condenser type, materials of construction (e.g. copper or steel), type of lubricating oil); - plant all-round performance: efficiency and compliance with current and future requirements;
- Evaluate Phase Out Options, i.e. use the information collected to assess options, taking into account the following factors: - age of the plant. An old plant (e.g. 15 years or more) should preferably be replaced, while a more recent plant might be suitable for modification to alternative (retrofit) refrigerants; - performance. If the plant is known to be inefficient, unreliable or unsuited to current and future requirements, plant replacement is the best solution; - plant design. Some plants are not well suited for refrigerant replacement. For example, if the plant already uses an HCFC Blend, it has probably already been converted from a CFC gas such as R-12 or R-502 as HCFC blends were specifically introduced as CFC refrigerant replacement options. In these cases, a second conversion could be impractical or difficult.
