This prototype was successfully tested and met the physics and electronics design criteria. The team faced design and manufacturing challenges, having a goal to produce 2 MW peak power at 13 duty factor, at the elevation of over 2 km in Los Alamos. Modified requirements: general and hood altitude correction, eyewash requirements for chemical treatment stations, coil requirements, use of de-ionized water for humidification, motor selection for fans. Made table of standards broadly applicable; changed LEM to ESM. Gave POC authority on low NOx waivers. Added requirements on directfired heater, 2-way valves, steam constants, mech room heat, boiler types and control, relief air dampers, duct lining, independent TAB. Also, when systems exceed the temperature and pressure ratings of the UMC or UPC, nationally recognized standards are used per 2003 IAPMO UMC, Section on hydronic piping. 2 At time of writing, ESM Chapter 14 required 30 better than ASHRAE; see that Chapter. Page 4 of 40. It is presented in the format of the 1993 ASHRAE Fundamentals Handbook, Load and Energy Calculations Division, Weather Data Chapter 24. Constants have been corrected for 7500 foot conditions. Page 5 of 40. Therefore, HVAC equipment operating at LANL produces less than its catalog rating. Correcting for this during design is required so that procurement of appropriately larger equipment occurs. Thus, in the procurement spec that s developed after the sizing calculations, this larger equipment should be specified, knowing it will be adequately sized when operating at LANL altitude. It should be the responsibility of the Contractor or the equipment manufacturer to make the needed adjustments to their equipment to meet the requirements at the 7500 ft elevation. The equipment manufacturer should be asked to provide submittal (fan curves, performance data) to back up their selection. A. Correct catalog data before applying it at LANL s 7500 foot altitude. Guidance: Failure to correct for altitude will result in undersized equipment. An increase in altitude means a decrease in air density and barometric pressure. Air moving equipment is rated and cataloged at sea level (standard air density pcf at 70 degrees and inches Hg barometric pressure) B. Guidance: Fans are constant volume devices and therefore air density has no effect on the volume delivered; however, it does affect the motor horsepower, static pressure, and mass flow rate. 3.2 Fan Selection Procedure at 7500 Foot Altitude (Guidance) A. Determine the actual volumetric flow rate (acfm) at 7500 feet. B. Using this actual flow rate (acfm) and standard air (sea level) friction data to design the ductwork, calculate the system static pressure at sea level. C. Select the fan by referring to sea level fan capacity tables and using the actual cfm required at altitude and the system static pressure calculated at sea level. The rpm shown in the tables is the rpm at which the fan must operate and need not be corrected. Page 7 of 40. Refer to Table D30-GEN-2 when installation environment involves nonstandard temperatures at 7500 feet elevation. TABLE D30GEN-2 3 Air Density Correction Factor at 7500 Feet Altitude Temperature Density Air Density Ratio (F) (PCF) (Nominal) E. High Temperature: Exercise caution in selecting the motor sizes for operating fans handling high temperature air. If a fan system designed to operate with high temperature air is started when the system is cold, the fan will require more horsepower during start up; therefore, the motor size should be selected for cold starting. 3.3 Air Conditioning and Refrigeration Equipment, Etc. A. Derate air-cooled equipment (e.g., chillers, coils, condensers, cooling towers, VAVs, VFDs) for altitude. Guidance: Consult with manufacturer and the following publications for derating data: 3.4 Air Compressors 1. Carrier: Engineering Guide for Altitude Effects. 2. Trane: Effects of Altitude on Air Conditioning Equipment. A. Derate the compressor air delivered (scfm) rating for altitude and temperature. Consult with the manufacturer for derating criteria. Page 8 of 40. Capture velocities and face velocities shall be as recommended in the latest ACGIH, Industrial Ventilation A Manual of Recommended Practice for Design.Page 10 of 40. Provide an approved P-trap at drip pan and pipe drip pans to floor drains Guidance: For best indoor air quality choice, slope drip pans in 2 directions. F. Properly size and configure condensate traps in accordance with the UMC 12 and the manufacturers recommendations. 14 G. Guidance: Use hot water for final heating coils. 15 H. Refer to the following LANL standard drawings for additional requirements: Preheat Coils A. General B. Design 1. Mechanical Drawing(s) ST-D30GEN-2, Water Coil Piping. 2. Mechanical Drawing(s) ST-D30GEN-3, Steam Coil Piping. 1. Building air handling units shall include a preheat coil upstream of chilled water or hot water reheat coils. The preheat coil shall be sized to heat building from initial 40 degrees to 55 degrees within one hour while maintaining minimum outside airflow requirements (for buildings with automation systems, the additional capacity to provide for minimum outside air requirements is not necessary if outside air dampers will be closed during warm-up) Operate face and bypass coils with constant steam or water flow. Do not modulate flow. 3. Provide a sensor in the discharge air stream to maintain a constant discharge air temperature, regardless of variations in inlet air temperature. 1. Design coils for an entering air temperature of minus 10 degrees F for 100 percent outside air systems. For steam coils, oversize condensate return piping to handle large condensate flow at startup IAPMO UMC, Section Trane Catalog CLCH-DC-7, Central Station Air Handlers, Application Considerations, recommended procedures for sizing condensate trap piping. (EMref 13) 15 Electric coils have a high operating cost that offsets any low initial cost. Steam coils are hard to control and require more maintenance than hot water coils. 16 The coil piping details provide piping details for different applications and additional design requirements. 17 Basis: Preheat enables reasonable time for cold weather startup and restart. Buildings would not be expected to drop below 40 deg since space heaters or the like would be deployed; similarly, above 55 degrees the reheat coils would continue warm-up. Lessons learned from MST Office Building. 18 Entering air design temperature based on lessons learned and historical climatic conditions. Page 11 of 40. The following are acceptable systems: a. Hot water coil with circulating pump to maintain a minimum coil water velocity of 4 fps. Refer to Mechanical Standard Drawing(s), ST-D30GEN-2, Hot Water Coil Constant Flow, Fail to Full Heat. b. Vertical tube integral face and bypass steam or water coils with clamshell type dampers to control airflow. 19 c. Steam coil with properly designed control valve, steam trap with check valve, and vacuum breaker. The temperature of the discharge air is controlled by proportioning entering air through the multiple heating and bypass channels of the face and bypass coils. The air is proportioned by clamshell-shaped dampers, which maintain a constant pressure drop, thus allowing a constant volume of air to pass through the unit. 20 The heating and cooling design temperature for general comfort is within the acceptable ranges of ASHRAE Standard, Figure The remainder of the heating temperatures is based on previous designs and DOE A, Table Page 12 of 40. See Coils subsection above MOTORS 8.1 Derating A. Pumps: Do not overload altitude-derated motors at any point on the pump curve. B. Fans: Do not overload altitude-derated motors beyond the design operating conditions of the fan curve. 21 Provides for a thermally comfortable environment that supports the productive and healthy performance of the building occupants. Compliance meets LEED Rating System 2.0 (2 points), Indoor Environmental Quality - Thermal Comfort. 22 Basis: Tapwater at LANL is high in silica and scale deposits will cause operational and maintenance issues. Page 13 of 40. Page 14 of 40. Supply air temperature, heating water temperature, space temperature or other indication of possible facility damage due to freezing shall be alarmed. Server rooms and other areas where equipment can be damaged by high temperatures shall be provided with high temperature alarms. D. Follow applicable sections of the standards for HVAC and nuclear air treatment systems (NATS) in Table D30GEN-2 which follows. They represent the minimum acceptable methods. Alternative methods including a graded approach (tailoring) may also acceptable, but approval by the ESM Mechanical POC is required. Any implementation methods selected must be justified to ensure that an adequate level of safety commensurate with the identified hazards is achieved. 26 Basis: Pumping costs are reduced on larger systems by the addition of variable speed drives. 27 Basis: One of the most effective energy efficiency methods is to turn systems off. Page 15 of 40. DG-1, Heating, Ventilating, and Air-Conditioning Design Guide for Department of Energy Nuclear Facilities.Ventilation and offgas systems are included as a vital part of the primary and secondary confinement design. B. Provide designs for periodic maintenance, inspection, and testing of components. Include adequate shielding in the design of filters, absorbers, scrubbers, and other air treatment components to ensure that occupational exposure limits are not exceeded during maintenance and inspection activities. Guidance: Recommended typical equipment layout details are available from the ESM Mechanical POC. C. Design to facilitate decontamination and demolition, including: 1. Location of exhaust filtration components of the ventilation systems at or near individual enclosures to minimize long runs of internally-contaminated ductwork. 2. Equipment, including effluent decontamination equipment, which precludes to the extent practicable, the accumulation of radioactive or other hazardous materials in relatively inaccessible areas, including curves and turns in ductwork. Accessible, removable covers for inspection and cleanouts are encouraged. D. Airflow and other design requirements for specific types of ventilation systems shall comply with 29 CFR 1910, Subparts G and H. Guidance: Ventilation systems for hazardous material protection should use local exhaust ventilation (LEV) to control concentrations of hazardous materials from discrete sources, or should control the number of air changes per hour for an entire room or bay (but avoid concentration control by dilution ventilation). Also, 29 CFR 1910, Subpart Z, provides requirements for monitoring and alarm systems for facilities that manage or use specific hazardous materials.The design should ensure that respirators are not required for normal operating conditions or routine maintenance activities except as a precautionary measure. 30 F. Guidance: Ventilation systems for hazardous material protection should use exhaust hoods to control concentrations of hazardous materials from discrete sources, or should control the number of air changes per hour for an entire room or bay. Air flow and other design requirements for specific types of systems must comply with 29 CFR 1910, Subparts G and H. Also, 29 CFR 1910, Subpart Z, provides requirements for monitoring and alarm systems for facilities that manage or use specific hazardous materials. Additional guidance on design of ventilation systems for hazardous material protection is provided in ANSI Z9.2 and ASHRAE 62. Decontamination facilities, safety showers, and eyewashes to mitigate external exposures to hazardous materials must be provided where mandated by 29 CFR 1910, Subparts H and Z. These systems must be designed in accordance with the requirements of ANSI Z358.1 and ANSI Z G. Guidance: Directed ventilation flow paths should be used to move contaminants away from worker breathing zones. The design should ensure that ventilation flow will cascade from clean areas to contaminated areas to preclude contamination spread. The design of systems must also preclude the accumulation of potentially flammable quantities of gases generated by radiolysis or chemical reactions within process equipment. 30 DOE G DOE G DOE G DOE G Page 19 of 40 Determine minimum flow requirements from pump curve (prevent dead-heading) and provide with either 2-way minimum flow valves or 3-way valves. If a minimum flow valve is used, it shall be placed at the end of the piping run. 38 E. For 100 outside air systems, use hydronic heating. Steam, electric resistance, and other methods allowed only with ESM Mechanical POC permission. 39 F.
