5 Basic system configuration2. Fresh Air Intake Indoor Unit Type34 HP systemConnecting limitation• The total capacity of the fresh air intake units and the indoor units is restricted to 80to 100% against the capacity of the outdoor units.• Up to two fresh air intake units can be connected on one line of the multi system.• The allowable total capacity of fresh air intake units shall be 30% or less againstthe total capacity of the indoor units (including the fresh air intake units).• The fresh air intake units only cannot connected.Capacity codeTotal 34No. of total units8Outdoor unit12HP 12HP 10HP3424 20 16 12 8036(4)036(4)036(4)036(4)036(4)036 Indoor unit(4)10Remotecontroller024 024 Fresh Air Intake Indoor unit(5) (5)Remotecontroller5 -3
SMMS-i <strong>Data</strong> book6 Equipment selection procedure1. Selection flow chart1 Determination of indoor air-conditioning load at each room.2 Preliminary selection of indoor units in the standard capacity no lessthan air-conditioning load at each room.3 Calculate corrected capacity A of each indoor unit by correcting ofindoor temperature for the standard capacity of each indoor unit.(Referto Chart [1])4 Preliminary selection of outdoor unit in the standard capacity no lessthan total values of corrected capacity A in indoor units. At the same time,check both connectable indoor units number and the outdoor unitdiversity(Connected ratio of indoor units to outdoor units) for thespecifications.5 Calculate corrected capacity B of each indoor unit by following 2 steps.Step1:Find the correction value of "Connecting pipe length and lift" byboth the longest length and the largest height with selected pipingcondition at 4 or 4’.(Refer to Chatrt [3])Step2:Calculate by multiplying the value of step1 by corrected capacity A.2’ Increase of indoorunit capacity at objectroom against airconditioningload6 Corrected capacity B of indoorunit >= air-conditioning load (for Allrooms)OKNGYES7 Find correction values of below items for the standard capacity ofoutdoor unit selected at 4 or 4’.Then determination of total corrected capacity of the selected outdoor unitby all multiplying.-Correction of indoor temperature condition(Refer to Chart [1])-Correction of outdoor temperature condition(Refer to Chart [2])-Correction of connecting pipe length and lift between indoor and outdoorunits by both the longest length and the largest height (Refer to Chart [3])-Correction of outdoor unit diversity in only over 100%(Refer to Chart [4])-Correction of frost condition on outdoor heat exchanger when in heating(Refer to Chart [5])NO5’ The correction characteristicof "connecting pipe length andlift"(Graph [3]) betweenincreased outdoor unit at ?’and preliminary selectedoutdoor unit at ? is different.(The both graphs aredifferent.)8 Calculate corrected capacity C of each indoor unit by multiplying thetotal corrected capacity of outdoor unit at 7by proportional division ofeach indoor unit standard capacity for total standard capacity of all indoorunits.5’ Increase of outdoor unit capacity.At the same time, check bothconnectable indoor units numberand the outdoor unit diversity9 Corrected capacity C of indoorunit >= air-conditioning load (for Allrooms)NGOKend6 -1
