3 DPS, DDS Series, DPQ, DDQ Series, DPV, DDV Series, DPM, DDM Series, DPUQ, DDUQ Series Controller Type Liners - Terminal Casing Price offers an extensive Terminal Unit Liner System to address the issue of terminal unit insulation fibers entering the air stream. Each liner system offers benefits that are designed to meet applications with various lining and insulation requirements. SM Solid Metal Liner System This system integrates a fiberglass insulating material with a solid sheet metal liner constructed from zinc-coated steel. The solid metal liner system complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) Solid metal liners offer the ultimate protection against exposure of fiberglass particles to the air stream. The fiberglass insulation is completely enclosed in metal all but eliminating the possibility of punctures exposing the fiberglass particles. This system is also resistant to moisture. The encased insulation pro vides thermal resistance, however, acoustic absorption of discharge noise is significantly reduced. The following thicknesses are available SM - 3 /4 in. [19] thick, R value=3.2 PM Perforated Metal Liner System This system integrates a fiberglass insulating material with a perforated metal liner constructed from coated steel. The edges are sealed with metal caps. The perforated metal liner system complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) The metal perforated liner system provides effective protection against damage of the insulation while maintain ing some acoustic value. Small fiberglass particles could conceivably still escape through the perforations and moisture can also be exposed to the insulation. The following thicknesses are available PM - 3 /4 in. [19] thicks, R value = 3.2 AFPM Aluminum Foil with Perforated Metal Liner System This system integrates foil-faced fiberglass insulating material with a perforated metal liner. The edges are sealed with metal end caps to prevent particles from entering the air stream. The double liner system (aluminum foil/ SM PM perforated metal) complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) The aluminum foil with perforated metal liner system provides effective protection against damage of the liner while maintaining some acoustic value. The aluminum foil prevents fiberglass particles from escaping through the perforations as well as resistance to moisture penetration. AFPM - 5 /8 in. [16] thicks, R-value =2.6 FF50 / FF Fiber Free Foam Insulation System This system integrates an engineered foam (FF50-1 /2 in. thick / FF - 3 /4 in. thick) which provides excellent insulating characteristics. The foam edges are self sealing due to the material s composition. The engineered foam meets the requirements of NFPA 90A complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) CAN/ULC M88 (Flame and Smoke) Fiber free foam insulation totally eliminates the risk of fiberglass particles entering the air stream while maintaining thermal resistance and acoustic absorption. An important advantage over other liner systems is that even scrapes or punctures will not expose fibers to the air stream. The foam also will not absorb water, reducing AFPM FF50 / FF FB (FF50) 1/2 (13) or (FF) 3/4 (19) the likelihood of mold or bacterial growth. Acoustic absorption of the foam insulation is equivalent to aluminum foil faced insulation. FB Foil Board Liner System This system integrates 4 lb. density rigid fiberglass insulating material with an aluminum foil liner. Exposed edges are coated with NFPA-90A approved sealant. The fiberglass insulation and aluminum foil liner complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) Acoustic absorption of aluminum foil lined insulation is reduced compared to standard unlined units. The aluminum foil liner is non porous, thereby protecting the insulation from moisture. Damage to the liner can expose fiberglass particles to the air stream. The following thicknesses are available FB - 5 /8 in. [16] thicks, R-value =2.6 F-191

[16] thick 4lb density fiberglass insulating material with an aluminum foil facing. All edges are sealed with metal endcaps and corner angles to prevent particles from entering the air stream. The liner s integrity is maintained where the damper shaft penetrates the insulation by a flanged nylon bushing. To reduce risk of liner damage during installation, sealed-in-place s-cleats are provided at the discharge collar. The inlet duct is sealed to the internal insulation with mold resistant caulking which meets ASTM D The fiberglass insulation and aluminum foil liner complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) Acoustic absorption of aluminum foil lined insulation is reduced compared to standard unlined units. The aluminum foil liner is non porous, thereby protecting the insulation from moisture. The smooth surface of the liner reduces the risk of micro-organisms being trapped in the material and also facilitates cleaning. Damage to the liner can expose fiberglass particles to the air stream. CRWF Cleanroom Woven Fabric System This system integrates fiberglass insulating material with a woven fabric liner. All edges are sealed with a metal end cap and corner angle to prevent particles from entering the air stream. The liner s integrity is maintained where the damper shaft penetrates the insulation by a flanged nylon bushing. To reduce risk of liner damage during installation, sealed-in-place s-cleats are provided at the discharge collar. The inlet duct is sealed to the internal insulation with mold resistant caulking which meets ASTM D The fiberglass insulation and fabric liner complies with the following industry standards and tests: UL 181 (Air Erosion) UL 181 (Mold Growth and Humidity) UL 723 (25/50) (Flame and Smoke) ASTM E 84 (25/50) (Flame and Smoke) ASTM C 665 (Fungi Resistance) ASTM C 1071 (Physical Properties) The woven fabric liner provides acoustic absorption equivalent to aluminum foil faced insulation with slightly improved attenuation at high frequencies. The fabric is more porous than aluminum foil, therefore moisture can be absorbed into the insulation. If the liner is damaged, fiberglass particles can be exposed to the air stream. The woven fabric liner has been specified in certain areas for many years and has a proven track record in health care applications, R value = 2.6.

5 DPS, DDS Series, DPQ, DDQ Series, DPV, DDV Series, DPM, DDM Series, DPUQ, DDUQ Series Controller Type Control Sequences Typical Dual Duct Control Settings Diagram 1 In this example, the hot deck and the cold decks are set for unequal calibrated maximum air volumes. When the thermostat is calling for maximum heat, the hot deck damper opens to the calibrated maximum air volume limit, while the cold deck closes to the full shut-off position. Both the hot deck and the cold deck in this example are calibrated for a minimum flow rate of zero. As room temperature rises following a demand for full heating, the total air volume of the assembly ap proach es zero. If the room temperature continues to rise, the cold deck damper will begin to open. The cold deck damper will continue to open until either the thermostat is satisfied or the cold deck calibrated maximum air volume setting is reached. Diagram 3 This diagram illustrates a constant volume application. The hot and cold deck calibrated maximum air volumes are set for the same maximum airflow rate. At a thermostat signal for maximum cooling, the cold deck flow will be at maximum set-point and the hot deck flow at zero. As the room temperature begins to decrease, the thermostat signal will decrease reducing the flow through the cold deck. The hot deck controller begins to open the hot deck damper to maintain a constant discharge volume. As the cold deck flow is reduced further, the hot deck flow increases until the cold deck is shut off. The proportions of hot and cold air are indicated by the broken lines. Flow Sensor Orientation Dual Duct Terminal is supplied with SP300 flow sensors on both inlet ducts. Also for all models except for DPV/DDV one downstream total flow SP300 sensor is always mounted at the discharge. For pneumatic and electronic sequences the cold deck inlet sensor and downstream total flow sensors are utilized for all standard constant and variable volume configurations. The hot deck inlet sensor is not used. When controls are supplied by factory or are field mounted, the appropriate sensors required will depend on the model of controls and application. To accommodate all variations and allow future field modification, both inlet and downstream sensors are supplied as standard. 3 1 Diagram 2 In this example, the hot and cold decks are again set for unequal calibrated maximum air volumes, however a minimum air volume is also provided. Mixing of the hot and cold deck flows occurs at the minimum setting. The proportion of hot and cold air are indicated by the broken lines. As room temperature decreases, the cold deck is modulated from maximum to minimum set-point. A further decrease in room temperature causes the hot deck damper to open as the cold deck damper closes. A constant minimum airflow is maintained during mixing. On a call for full heat, the cold deck closes and the hot deck increases to its maximum set-point. Diagram 4 This diagram illustrates a constant volume application similar to diagram three, however the cold deck is calibrated with a minimum set-point of 20%. When the thermostat calls for full heating, the total supply volume will consist of 20% cold deck and 80% hot deck. The proportions of hot and cold air are indicated by the broken lines. 4 2 F-194

6 DPS, DDS Series, DPQ, DDQ Series, DPV, DDV Series, DPM, DDM Series, DPUQ, DDUQ Series Controller Type Selection Guidelines When sizing dual duct terminal units, the table of calibrated air volume ranges should be consulted to verify that the air quantity proposed for a given unit size, is compatible with the capabilities of the con troller. To illustrate, we will comment with reference to the control diagrams on page F222. In Diagrams 1 4 for the unit size selected, the maximum cold deck air volume pro pos ed must fall within the limits of the calibrated maximum air volume range as listed in the table for that unit size. Sim i larly, the hot deck air volume proposed must also fall within these same air vol ume range limits. If both air volumes pro posed do not fall within these limits, con sideration should be given to select ing a smaller unit size and/or modifying the proposed air volumes to bring them within the listed limits. In Diagram 2, the mixed air volume is equal to the minimum hot and cold deck value. This volume must fall within the minimum values listed in the table. In Diagram 4, the minimum cold deck value must fall within the minimum values listed in the table. A standard unit is supplied with both the hot and the cold inlets of the same size. Where there is a large difference between the maximum hot and the maximum cold air quantities, and the smaller maximum air quantity is at or below the lower limit for the calibrated maximum air volume range for that unit size unequal inlets should be considered. Each inlet would then be sized to accommodate the maximum air quantity required through that inlet. When unequal inlet sizes are used, the casing size will be governed by the larger inlet size, in accordance with the dimensional table on pages F215-F219.

9 DPS, DDS Series, DPQ, DDQ Series DPM, DDM Series, DPUQ,DDUQ Series Controller Type Typical Selection Guide NC levels presented in the Typical Selection Guide are based on typical attenuation values as outlined in AHRI Standard , Appendix E. AHRI Standard , Appendix E provides typical sound attenuation values for air terminal discharge sound and air terminal radiated sound. The typical attenuation values are recommended for use by manufacturers to estimate application sound levels. In product catalogs the end use environments are not known and the factors presented in AHRI Standard are provided as typical attenuation values. Use of these values will allow better comparison between manufacturers and give the end user a value which will be expected to be applicable for many types of spaces. Following is a detailed description of the typical attenuation values used to determine NC levels. Radiated Sound Table E-1 of Appendix E provides typical radiated sound attenuation values for three types of ceilings: Type 1 Glass Fiber; Type 2 Mineral Fiber; Type 3 Solid Gypsum Board. Since Mineral Fiber tile ceilings are the most common construction used in commercial buildings, the attenuation values in the Typical Selection Guide are based on Type 2 Mineral Fiber. The following table provides the calculation method for the radiated sound total attenuation values based on AHRI Standard Mid Frequency, Hz Environmental Effect Ceiling/Space Effect Total Attenuation Deduction The ceiling/space effect assumes the following conditions: 1. 5/8 in. tile, 20 lb/ft 3 density. 2. The plenum is at least 3 ft deep. 3. The plenum space is either wide (over 30 ft) or lined with insulation. 4. The ceiling has no significant penetration directly under the unit. Discharge Sound Table E-1 of Appendix E provides typical discharge sound attenuation values for three sizes of terminal units. 1. Small box defined as a unit with discharge duct of approximately 8 in. x 8 in. and capacity less than 300 cfm. 2. Medium box defined as a unit with discharge duct of approximately 12 in. x 12 in. and capacity between cfm. 3. Large box defined as a unit with discharge duct of approximately 15 in. x 15 in. and capacity of greater than 700 cfm.

The laboratory attained discharge and radiated sound power levels for each unit at various flows and inlet static pressures is presented in the Acoustical Data tables. This data is derived in accordance with AHRI Standard 880 and shows the 'raw' sound power levels of the terminal in the second through seventh octave bands with NO attenuation allowances. This data includes AHRI standard ratings which are on record with the Air-Conditioning Refrigeration Institute. Price also offers this Typical Application and Selection Guide to assist you in selecting the proper size and configuration of terminal for your needs. The attenuation allowances listed are based on F-202 values suggested in AHRI Standard , Appendix E. The suggested attenuation allowances are intended to be representative of typical jobsite construction. If your conditions differ significantly from these it is recommended you utilize the sound power level data on pages F149-F150 and the procedures outlined in AHRI Standard If the NC levels listed in the Price catalog are being compared to other manufacturers cataloged NC information, a careful review of the other manufacturers attenuation allowances must be made. If allowances other than recommended AHRI Standard , Appendix E are used, a fair comparison of NC levels cannot be performed.
