General

15 ACCESSl SPECTION OPENINGS

151 General These are for inspectionservici ng on 1y

HVCA publication DWIl44 Part 7 - General Section 20 sets out the requirements for access applicable to this specification

152 Cleaningmaintenance Designers shall take specialist advice and then stipulate their requirements for the periodic internal cleaningmaintenance of ductwork and of the consequent need for adequate access for specialist cleaning equipment including the size type and locationfrequency of the actual access openings required

Appendix D sets out guidance notes for the consideration of cleaning access and also makes reference to the HVCA publication TR 17 Guide to Good Practice Cleanliness of Ventilation Systems which covers the su~ject

in greater detail

Note A majority of in tallations in which plastic ductwork is used are considered to have a nigb operational risk potential and provision of access should address this

16 REGULATI G DAMPERS

161 General Balancing dampers and control dampers are elements inserted into an air di tribution system or element of an air distribution sy middottem Balancng dampers permit modification of the air resistance of tbe system and consequently cbanging of the airflow rate Control dampers control tlle airflow rate and may in addition provide low leakage closure of the airflow

The deigner shall specify damper locations taking into consideration that good design practice requires a minimum of five times the diameter or width of the shortest side of uninterrupted flow between plant connections and the damper and select the damper type as

characteristics

1611 Balancing damper To achieve the required distribution of air in the ductwork system at inlets andor outlets for [hi purpose the damper blades are set and Jocked manually in position between fully open and fully closed

1612 Control damper To secure dynamic control of the air now in the ductwork system In thi function the damper will always be power actuated and may require to be modulated between fully open and fully closed and to be capable of taking up any position between these extremes In the fully open position the damper should have a minimum pressure drop In the fully closed position it will not necessarily achieve a complete shut off

162 Types of airflow control dampers Airflow dampers of various types are available for specific purposes as follows

1621 Single - blade dampers Single-blade dampers shall consist of a si ngle pi voted blade cOlllained withjn a casing or section of ductwork The blade shall be adjustable tbmugh a nominal 90 angle by means of a quadrant or similar operating mechanism Where automatic control of the damper is required the spindle shall be extended to enable a powered actllator to be mounted

Single-blade dampers shall have a maximum duct width of 400 nUll and a maximum duct height of 400 mm for rectangular ducts and for circular ducts a maximum diameter of 400 mm

1622 Multi-blade dampers Multi-blade dampers shall consist of a number of pivoted blades contained within a casing The blades shall be

22

DW154 Sedicalirm for Plastics Ductwork

adju table through a nominal 90deg angle simultaneously by intershyconnected linkage or gears connected to a quadrant or similar operating mecbanism Where automatic control of a damper is required a spindle shall be extended to enable a powered achlator to be mounted

There is no restriction on the size of duct in which multi-blade dampers or damper assemblie may be u ed Where dampers are required for blade lengths in excess of 750 mm the blades should be suitably reinforced or supponed 0

individual damper blade should exceed 200 mm in width

1623 Iris dampers Lris dampers shall consist of a nUlllber of radialty interconnected blades which open or close within a casing with duct COlll1cctions The blade shall be simultaneously adjusted by a quadrant or similar operating mechanism

Iris dampers shall be installed as specified by the manufacturers operating and installation instructions where the product is unidirectional with regard to airflow

lris dampers are available for circular ducts only in diameters up to 250 mm (it should be noted that the damper casin i appro)(imately twice the diameter of the duct)

1624 Backdraught dampers Air pressure operated uni-directional rectangular (single or multi-blade) with adapters if fitted to circular ducts

1625 Slide and blast gate dampers A damper [lsed as a shut off facility with an externaJ Lide bousing allowing the blade configuration to be fuJly inserted to fully extended for maxiDlUlll air flow

DW154 SpedjimioTl for Plastics Ductwork

22 THERMAL INSULATION

221 The provision and application of thermal insulation to ductwork is not the responsibility of the ductwork contractor

222 Where ductwork is required to be preshyinsulated the specification should be agreed with tbe designer

223 Where the temperature of the air within the duct promotes condensation on the exterior surface of the duct and cause moisture penetration througb the thermal insulation vapour scaling may be required and in this case the most important requirement is to limit penetration of the seal

The extent of any vapour sealing of ductwork thermal insulation and the support method to be u ed must be clearly pecitled in advance by the designer

224 For detailed information on the thermal insulation of ductwork reference should be made to BS 5422 1990 which covers the specification for thermal insulation materials on pipes ductwork and equipment (in the temperature range -40degC to +700degC) and BS 5970 1992 which is a Code of Practic for Thermal Insulation of Pipework and Equipment (in the temperature range -lOOdegC to +870degC)

23 FIRE RETARDANT FINISHES ON PLAST C DUCTWORK

231 The designer should note tbat ductwork constructed to DW154 has no teted fire rating or information see Appendix C

24 REINFORCEMENT OF DUCTS WITH GRP LAMINATE

241 General Where ductwork is required in larg T izes than are covered by Tables 2 4 6 amp 7 or with the increased strength sometimes necessary for industrial use external reinforcement is normally pwvided by applicatioD of glass fibreresin laminate

GRP systems will bond satisfactorily with standard UPVC sheet but for pp it is

nece sary to use a specially prepared sheet with a glass fabric backing incorporated dOling manufactllfe

The detailed techniques of fabrication using GRP are outside the scope of this speci lcation but the following notes are offered for guidance of ductwork fabricators

242 Materials

2421 Quality The laminate is made up of polyester resin complying with BS 3532 and glass fibre complying with BS 3496 or BS 3749 The nominal ratio of resin to glass fibre should be 7030 by weight

2422 Minimum properties The laminate shall comply with the followiog mini mum pbysical properties

Tensile strength - 70 MNm Tensile modulus - 7 Gl m Flexural strength - 140 M Im Bond strength (hetween laminate and substrate Not less than 7MNm Bmcol hardnes Not le s than manufacturers specification

The GRP reinforcement educe the expansion of the parent material but the resultant stre ses arc well within rhe strength of the bond However the Iinear thermal expansion curve shown in Figs 34 amp 35 will serve as a guide

Surface resistivity electrkal propcltles and acoustical propertie are similar to the relevanl unreinforced materials The fire retarding properties of GRP may be improved by the use of specialisl laminating resin

2423 Forms available GRP Laminate should be built up from the separate materials ie resin aod glass fibre in the form of chopped

I strand mat or spray ravings

28

DW154 Spcification for Plastics Ductwork

2424 Workshop conditions Polyester resuls are sensItIve to lmperature and the workshop hould b maintained at a temperature of herween 20deg and 25degC HiOh relative humidities and damp onditions should be avoided A good rate of air change must be pro icled pJeferably by m chanical ventilation

2425 Storage of materials Resin and urin o agents shouJd be stored in dark cool condirions away from the working area and in confonnit with statutor requireshyments for tJle middottorage of flarmnable liquid Because of Ule Limited torage lif of the unmixed resin and curing a eot mal lials ~hould be ch eked before use to enLlfe that they are within the manufacturer pe ified sh If life (usually ix month from the dm of manufacrure)

Glass fi re should be stored separately und r clean dry conditions

243 Surface preparafon

2431 UPVC To achieve the specified bond strengtll the urface to which the GRP is applied mut first be thoroughly cleaned and then etched either by mechanical means or by the use of a suitable solvent

2432 pp with glass fabric backing To achieve the specified bond middottrength the fabric backing must be thoroughly impregnated Witll resin

244 Mixing the materials for use The re in 1 a three part mix compri lng base I sin hardener and accelerator The manufactur rs pecj[ied proportions are critical and th llUxmg sequenc pecified must be meticulously foUowed

The resin has a very limited life after mixing and before u e It is dependent on the characteri tics and bulk of th resin the alllount of hardener the degree and method of acceleration and the workshop onditions

245 Methods of application

2451 General The mixed resin may be applied by hand or b pray c1epoition The operation must b completed within the gel time of th y tern and tbe laminat fully cOI1olidated to achi v the phy ieal properties pecified

2452 Hand lay-up The duct surface i coated by hand with resin Llsing a brush and a mar of gla fibp orked in until full consolidation achieved Th proc is repeated untiJ th requird thicknes i obtained

2453 Spray depo Won The duct surface is coated WiUl re in by spray gun with the chopped glass roving added through a separate nozzle The full thickne i obtain d in layer with con olidation of each layer by hand roller

Air Leakage From Ductwork To be read in conjunction with DW143 A practical guide to Ductwork Leakage Testing

CAUTION As highlighted ill both this docul1lenr and DW14 I lot ellough emphasis can be placed 01 the fact that except for high pressure class C the much more stringent ductwork constructional standard brolght about b the general acceptance of DW154 have irtlally negated the requirement for leakage-testing It is essential lO realise lhat except where it is mandatory this doclllllelll is nOl an endors ~lIlent of the rourine testing of ducts bllt purely a guide to outline the procedures for cononnity with the air leakage limits ill Table l Where the specified methods of assembly and

A3sealing of dlcls are u ed a vi ual inspection wil ordinarily sl~fll e for ver(iatioll of a well engineered and a ceptahfy airtight COl1strucrioll WHERE NOT MANDATORY DUCT LEAKAGE TESTING IS GENERALLY AN UNJUSTIFIED AND SUBSTANTIAL EXPENSE

A1 INTRODUCTION L akage from ducted air distribution systems is an Lmportant consideration in the design and operation of ventilatjon and air conditioning middotystems A ductviork t)ystem tbat ba limited air leakag within defiucd limits wiH cnsUft

that tile design characteristics of the sytem can be maintained It wilJ also ensure that energy and operatLonal cosb are maintained at optimum levels DucLwork constlucted and Ulstalled in accordance with DW154 should minimise a level of air leakage that it) appropriate to tll operating static air pre sur in tile system

A4However it is recouuised that tbe environment in wtJich middotystems are installed is not always conducive to achieving a predictable level of quality in term of system ajr leakage and it is therefore accepted that designer may sometimes require tlle ystem to be tested in part or in total It should be ecogni ed that the testing of duct systems add a ignificant cost to the installation and incur some extra tjm within the programme (Se 47 and 64 re mandatory te-sting)

manufactured to a structural standard that is compatible with the system operating pressure There are three classes of duct con truction to eorre pond with the three pre ure clas meations Class A Lo pressure ducts suita le for a maximum positive operating pressure of 500 Pascal and a maximum negative pressure of -500 Pascals Class B IVledium pressure ductmiddot suitable for a rnaxilnuJJl positive operafjn o pressure of 1000 Pascals and a maxllnum negative pre sure of -750 Pa cal Class C High pre sure ducts suitable for a maximum po ilive operating pressur of 2000 Pa cals and a maximum negativ pres ur of -750 Paltcals

LEAKAGE FROM DUCTWORK Leakao-e front pia tic air ducts occur at the joint~ and is therefore proportional to the total surface area orthe du twork in th system Tb level of leakage i imilarly related to tIle air pres ure in th du t system and whilst there LS n precis formula for calculating the level of air los it i generally accepted that leakage will increase in proportjon to pressure to rbe pOvver of 065 The effect of air leakage from high pressure velocit ductwork is critical tn terms of system perfomlan dege energy consumption and the risk of high frequency noise as ociated with leakage These problems are le critical with medium pressure 10 ity systems but should be con idered Low pres mevelocity ducts present the lowe~t

ri k in tenn of tbe effect of leakage on the operation of the s stern

SYSTEM LEAKAGE LOSS As there i no di ct relatLonship between th volume of air conv yed and the surface area f the ductwork sy tern required to match the building configuratmn it is difficult to express air leakage a a percentage of total air volume Similarly the operating pressure will vary throughollt lh 3 system and a leakage is related to pre me the calculations ar comple However it is generally ac epted tbat in typical good quaJjty systems the leakage from

each class of duct llnd r operating condition will be io the region of CIa S A low pressure 6 Clas B medium pres un 3 Clas C high pressure 2

A5 SPECIFYING AIR LEAKAGE TESTING Re peeting both the co -t and programme implications a sociated with te ling du 1 for leakage the designer may for example indicate that a particular system is te ted as follow

a) High pressure ducts - all tested b) Medium pr ssure duets - 10 of the

ductwork shall be s eet d at random and tested

c) Low pre sure - unte ed In any case where a random te t i elected for medium pre sure ductmiddot the followin c1au~e is suggested for inclusion by the de ign r

The designer hall elect at random a maxirnwlI of 10 of the dUCl system to bt tested for air leakage The duct hall be tested af the pressure recommended in Table J3 for the assifi atiol for the ectiol1 of the ductwork that is to be tested The tests shall be carried Ollt as the work proceeds and prior to the application of thermal insulation In the event of test failure of the randomlY selected section the designer shall have The right to select two La1her e tiolls at random for resting Where succes ive failures are identified there shall be a Tight to require rhl COl11raCWr 10 apply remedial attention to the complete ductwork system Th contractor shall provide documented eviden e of the calculalions used to arrive (1

and air leakage classification for the y em under test

DESIGNERS CALCULATIONS The designer can middotaJculate with reasonable accuracy the predicted total loss from a ystem by

a) Calculating the operatin presure in each ection of the sy tern

b) Calculating the surface area of the ductwork in each correspondin pre lire s ction

c) Calulating the allowabl~ los at the operating pressure for each ection of the system (see table 13 for allowable leakage figures)

VARIABLE PRESSUR S IN SYSTEMS De igner can achieve significant co t saving by matchina operating pressures throughout the system to constmctional standard and appropriate air leakage testing eO the practice of specifying construction tandards for whole duct sy tems based on fan discharge pre sure may incur unnece sary costs on a project For example ome large sy terns ould well be classiC ed for I akage limits as follows

conditions Test results are given as an index of Perfonnance (i) whicb is based on three sub indices (iJ (i1) (h) The higher the value of the Index of Performance (i) the greater is the material s contribution to fire growth The higher the value of the sub-index 0) rhe greater the ease of ignition aod flame spread The highest product performance classification as defined in Approved Document B of the Building Regulations is Class O This is acLlieved if a material surface of a composite ploduct i~ either a) composed throughout of materials of

limited combustibility or b) a Class I material which has a tlre

propagation index (i) of not more than 12 and sub-index (i l ) of nor more than 6

01 J Class 0 is not a cla$sif1cation identified in any British Standard test

There are resin system reported to be classified to Class O when tested to BS476 Pcl1S 6 and 7 however designers need to ensure that such sysrems can be applied to their proposed design In propriety resinmat system available the fabrication techniques and COITect application are critical to the integrity of the reinforcing and clas ificatiol1 For example in some systems the u e of a non-fire retardant gelcont on a fire retardant substrate would reduce the classification For further information see HVCA publication DW144 Appendix D

D1 GE ERAL This appendix highlight in ummary fOI111

the acce considerations that hould be made by the design r iD terms of inspection servicing and cleaning Having considered the seop and the design of the dUCI work system relative to the guidelines outlined below the designer should clearly indicate which levels of acces should be incorporated into the manufacture of a new duct work system (See Table 14 and Note I b low it

D2 DESIGN CONSIDERATIONS

D21 In ptction and servicing requireshyments are set out in Section 15 of Lhis specification

D22 Cleaning requirements are set out in the HVCA pubUcation TRl7 Guide to Good Practice Clean Lines of Ventilation Systems and the guide tates The precise location ize and

type of access would be dependent on the type of ductwork cleaning inspection and te ting metbods to b adopted Care protection and standards of cleanliness prior LO cOlllmisionin o

are set out in th AV A publication DWITM2 Guide to Good Practice Internal Cleanliness of New Ductwork Installations and th guide state Wh re specific limits of cleanliness are required ductwork sball be cleaned after installation by a spcialist cleaning contractor It will b in the interests of tht desioner botb financially and practically to cunsider employing a specialist c1eauing contractor at tbe

outset of a contract to internally clean newly installed ductwork prior to bandover This approach would reali e the following benefit shyi) Tb actual numb r of cleaning

access panels could be detennined to suit the method of cleaning to be adopted (This may be 1 s than the maximum requiremen listed under Lev 13 of Table 14)

ii) Clear directions could b given to the ductwork contractor as to tJle size and location of cleaning access panels that are required to be fitted during the mauushyfaclunng pro s

iii) The specialist cleaning operation prior to commi ioning vould enable the cleaning contractor to verify the practical acee requirement for the future cleaning operation associated -vitb a regular maintenance programme

iv) A specialist cleaning operation prior to commissioning would allow the designer to omit from the speeilicatiolJ the DWrrM2 requirem nt for factory sealing protection wipe downs and capping-off

v) Specialist Ieall ill 0 to the measurable standard defin d in TR17 will allow an objective definition of cleanline to be achieved

Car ful consideration must be gIven by the designer to the practl aJ problems associated witb the manufacture and fitting of suitably si Led access panel on small cross section duct and on the circular faces of rouod and flat oval ducts in particular

D23 Special con ideration must be given by the de igner to the practical problems associated with gaining personnel access to heavily congested ceiling areas and multi-la red du twork systems This approach would avoid
