Daikin RYN25LV1B [10/152] Allowable piping length

Содержание

______________________________________ REFRIGERANT PIPING_________________________________________ Allowable Piping Length If the pipe is too long both the capaeity and reliability of the unit will drop As the number of bends increases resistance to the flow of refrigerant system increases thus lowering cooling capacity As a result the compressor may become defective Always choose the shortest path and follow the recommendations as tabulated below Model FTYN 20 25 35 60 50 3 Min Allowable Length L m Max Allowable Length L m 12 15 Max Allowable Elevation E m 5 8 Gas Pipe Size mm in 9 52 3 8 Liquid Pipe Size mm in 12 70 1 2 15 88 5 8 6 35 1 4 Be sure to add the proper amount of additional refrigerant Failure to do so may result in reduced performance Remark The refrigerant pre charged in the outdoor unit is for piping length up to 7 5m Equivalent length for various fitting meter Pipe Size L joint Trap bend ESU 3 8 OD9 52mm 0 18 1 3 1 2 OD12 7mm 0 20 1 5 5 8 GDI5 9mm 0 25 2 0 3 4 0D19 1mm 0 35 2 4 7 8 OD22 2mm 0 40 3 0 1 OD25 4mm 0 45 3 4 1 1 8 OD28 6mm 0 50 3 7 1 3 8 OD34 9mm 0 60 4 4 Notes 1 Equivalent piping length is obtained with actual length of gas piping 2 90 bend of piping is equivalent to L joint Bending must be carefully made so as not to crush the pipe Use a pipe bender to bend a pipe where possible 1 8
