QUOTE(kimsim @ Jan 5 2015, 11:24 AM) Room size in meter thanks for the tips. 1hp for 3x4 = 12sm (15sm) do not exit 15 sq meter. 1.5hp for 5x4 (25sm) 2hp for 6x5.5 (33sm) 2.5hp for 7x6 (45sm) Once exit the room size meaning under power would be used more waste energy Height is does not matter how height of that, more than 5m in 3x4m for 1hp still keep cold. Cold air would going down 1st.  |
