- 1 4 kg i e if the piping length is 27 m are not subjected to any requirements to the installation room 61
- If the total refrigerant charge in the system is 1 4 kg i e if the piping length is 27 m you need to comply with the minimum floor area requirements as described in the following flow chart the flow chart uses the following tables 16 table 1 maximum refrigerant charge allowed in a room indoor unit 4 260 16 table 2 minimum floor area indoor unit 4 261 and 16 table 3 minimum venting opening area for natural ventilation indoor unit 4 261 61
- Information 61
- Multiple indoor units if two or more indoor units are installed in a room you must consider the maximum refrigerant charge that can be released in the room when a single leak occurs example if two indoor units are installed in the room each with its own outdoor unit then you have to consider the refrigerant charge of the largest indoor outdoor combination 61
