The McQUAY MULTI-ZONE AIR CONDITIONING UNIT ... is specifically designed for buildings in which heating and cooling are required simultaneously. This can commonly develop in mild weather due to different solar exposures, changing internal loads, etc. The unit is so constructed that it can deliver to any one of many different zones in a building, either filtered, cooled and de­humidified air, or filtered, heated and humidified air; or a mixture in any proportions of these two types of air supply.

Important Features

• Eight (8) sizes- 1370 CFM to 21,000 CFM.

18 Both Horizontal and Vertical Units.

• Full line of accessories- Preheat Steam Coils, Filter Sections, Mixing Boxes, Humidifiers, etc.

e Low fan outlet velocities- approximately 1600 FPM fan outlet velocity at 500 FPM cooling coil face velocity.

• Same rugged type of construction as used on the McQUAY "AC" and "HC" Jines.

• Yz" thermal-acoustic insulation furnished as standard.

• For best BTU/dollar performance and to help equalize static pressures, the face velocity thru the heating coils is approximately 900 FPM when the cooling coil face velocity is 500 FPM.

e Double Tube Steam Coils are furnished as stand­ard in all Models to provide minimum variations in leaving air temperatures across the coil face. The three smallest units have type "J" coils with steam supply and return on the same end. The five largest units have type "DJ" coils with steam fed from both ends and one common return.

• All steam coils are pitched towards the return connection for proper drainage of condensate.

• Two types of Discharge Sections are available for all units - Horizontal and Angular. Angular Section is designed for vertical air discharge or a combination of vertical and horizontal air dis­charge.

It Zone Damper Section is a separate section from the balance of the unit and thus can be omitted

so that the unit may be used with a Double Duct System.

e Each size unit has a standard number of zones available- from 6 on the smallest to 22 on the largest. Each available zone consists of one hot air damper and one cold air damper which are mounted on a common shaft in such a manner that when one damper is fully closed, the other is fully open or vice versa. Each zone is separated from adjoining zones by a divider plate.

• All the zones are interconnected by a single ex­ternal connecting rod which can be cut in the field to satisfy the required number of zones. This standard zone damper arrangement eliminates the necessity of specifying the number and loca­tion of the zones when ordering, and this permits last minute changes in design which would not be possible if the size and location of the zones were made to order.

• Ample space is provided between the fan dis­charge and the cooling and heating coils to assure uniform air distribution across the coils.

• When both cooling and heating coils are required and there is an appreciable difference in air re­sistance between the two coils, a balancing plate will be provided so that the air resistance will be approximately equal for each coil system, thus minimizing fluctuations in air deliveries between the two systems.

• The Drain Pan is located internally, sloped to the drain connection, and extends underneath the entire cooling coil. It is constructed of continuous galvanized steel, coated with mastic for added protection against corrosion and insulated ex­ternally with thermal insulation.

SOLUTION

1. From the Fan Performance Table on Pages 6 and 7 it can be seen that a Model MC216 UI1it will deliver 6550 CFM with a fan outlet velocity of 1605 FPM and that the cooling coil face velocity will be 500 FPM. 2. From the General Specifications Table on Page 11 it is found that the maximum number of zones is 12 for a Model MC216 unit. Each available zone in a McQuay Multi-Zone unit consists of one hot air damper and one cold air damper which are mounted on a common shaft in such a mannpr that whPn one damper is fully closed, the other damper is fully opPn or vice versa. Each zone is separated from ·adjoining zonPs by means of a divider plate. However, all the zones are intercon­nected by means of a single external connecting rod which can be cut ·in the field to satisfy the required number of zones. So, in this particular case, for Zone 1 (1640 CFM-:- 6550 CFM) x 12=3, therefore the interconnecting rod would be cut so that three (3) dampers remain tied together. For Zone 2 (2300 CFM-:-6550 CFM) x 12·· 4.2, use four (4) dampers; for Zone 3 (2610 CFM-:-6550 CFM) x 12• 4.8, use five (5) dampers. The actual delivery for the three zones with the McQuay Model MC216 would be:

Zone 1 .. . ........ 3-:-12x6550CFM 1640CFM

Zone 2 ... . .4-;.-12x6550CFM 2180.CFM

Zone 3 ... . . . . . . . . . . . . . . . 5 -:- 12 x 6550 CFM- 2730 CFM

3. From the Nominal Rating Table on Pagt• ;; it is found that at the entering conditions of 80°F. D.B. and 67"F. \V.l3. air temperatures and 40°F. refrigerant tt·m1wratun•, a Model MC216 unit equipped with a 6 row din·ct pxpansion coil (Model X86) will produce 25.41 tons or 304,920 l3TU/HR. with a !paving air condition of 53.0" F. D.B. and 51.7" F. W.B. 4. Also from the Nominal Rating Table it is found that at the entering conditions of 60°F. air temperature and 2 psig. steam, a Model MC216 unit equipped with a D.J81 steam coil will produce a heating capacity of 258,500 BTU/HR. 5. To select a motor, it is first necessary to find the total static pressure the unit must operate against. To determine the total static pressure add the internal resistance of the unit to the specified external static pressure. When both a cooling and heating coil are required in a unit, determine the intc>rnal re­sistance by calculating the air friction through th<> cooling coil system. (In the majority of cases the air friction through the> cooling coil system will be somewhat greatpr than through tlw heating coil system and when there is an appreciable difference between the two systems, a balancing plate will be provi(h•d so that the air friction will be approximately (•qual.) Th(•refore, in this particular case, the total static is de!Prmined as followH by using values from Table I:

TOTAL 1.28" Water

Now referring to the Fan PerformancP Tabh· on Pagt>s G and 7 it is found that an MC216 handling Gf)50 CFM at 1.28" total static will require between 2.:32 BHI' and 2.!>fi BHP. ThPrPfon', a 3 HP motor is rf'quired.

*For clry coils (sensible cooling only) dividP the wet coil values shown by 1.3fi.

1. Do not include the heating coil air friction in the unit re­sistance unless the heating coil is to be the only coil furnished with the unit (no cooling coil required.) ln these cases. the heat­ing coil air friction can be obtained by calculating its face veloc­ity in FPM and referring to Fig. 4. Catalog 404 for hot water coils or Fig. 1. Catalog :~04 for steam coils. The heating coil referred to in this explanation is the heating coil installed in tlw cooling and heating coil sP<'Iion- not a preheat coil.

2. lf a preheat coil is required. its air friction must be considen·d in determining the unit's internal resistance. Determine the pre­heat coil air friction by calculating its face velocitv in FPM and referring to Fig. 1, Catalog :l04 for steam coils. ·

J. To determine the air friction of combination mixing box and filtN sections. add the individual resistnncPs of the filtns and the mixing box at the applicable> cooling coil facl' w·locitv.
