LLHE Updates OM to Include “Certify-all” Policy

At the start of 2014, the Liquid to Liquid Heat Exchangers (LLHE) certification program underwent major revisions to its Operations Manual (OM), including changes to the program scope. A new “certify-all” policy will require manufacturers participating in the LLHE certification program to sell only AHRI Certified ® gasketed plate heat exchangers if they fall within the following criteria:
  • Heat duty between 0-24 million Btu/h;
  • Flow rate between 0-2,000 gpm;
  • Utilizing water and/or sea water; and
  • For “HVACR applications” only.
AHRI defines “HVACR applications” as equipment located in a residential or commercial building exclusively used for conditioning spaces for the occupants of the building. The updated OM is available on the AHRI website under “Product-Specific Operations Manual (Effective Date: January 2014).”

In addition, contractors, specifiers, and design engineers are now able to verify the software outputs of LLHE performance ratings to ensure the reliability of data supplied by the manufacturer. This service facilitates the comparison of certification participants’ software output, including heat duty, heat transfer area, volumetric flow rate, and pressure drops, with the output obtained through that same participant’s selection rating software housed with AHRI. This information is not publicly available on the AHRI Directory of Certified Product Performance. Contact: Richie Mohan.

ASHRAE Issues Call for Comments – Due May 4

Comments are invited by ASHRAE on the Public Review Drafts of the following ASHRAE standards and standards addenda. The Public Review Drafts can be accessed by visiting ASHRAE’s Standards, Research & Technology/ Public Review Drafts web page and following the instructions to access the online comment database. To obtain a paper copy, contact Stephanie Reiniche.

ANSI/ASHRAE Standard 16-1983(RA), Method of Testing For Rating Room Air Conditioners and Packaged Terminal Air Conditioners. This standard prescribes a method of testing for rating room air conditioners and packaged terminal air conditioners.

ANSI/ASHRAE Standard 58-1986(RA), Method of Testing for Rating Room Air Conditioner and Packaged Terminal Air Conditioner Heating Capacity. This standard prescribes test methods for room air conditioners and packaged terminal air conditioners equipped with means for room heating.

Addendum a to ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality. Currently, 62.1 has responsibility for multi-family residential buildings of four stories or more and 62.2 has responsibility for buildings with three stories or less. This proposed scope change would remove the building height threshold, bringing all dwelling units under 62.2 regardless of height, while common areas would be covered by 62.1.

Addendum g to ANSI/ASHRAE Standard 62.2-2013, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. This scope change would remove the building height separation, bringing dwelling units under 62.2 regardless of height. This will allow for consistency within dwelling units and also allow application of ASHRAE ventilation standards to the multi-family retrofit market.

Addendum c to ANSI/ASHRAE Standard 145.2-2011, Test Method for Assessing the Performance of Gas-Phase Air- Cleaning Systems: Air-Cleaning Devices. This addendum modifies the initial performance test to allow testing to stop when the penetration exceeds 0.95.

Addendum ax to ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance Buildings Except Low-Rise Residential Buildings. This addendum modifies the original addendum by not allowing the use of any control factors from Table 9.6.3, Control Factors Used in Calculating Additional Interior Lighting Power Allowances, of ANSI/ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, for lighting control methodologies.

ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance Buildings Except Low-Rise Residential Buildings
  • Addendum ay: This addendum modifies the outdoor airflow rate levels where demand control ventilation would be required to make it more consistent with reasonable system equipment sizes.
  • Addendum bh: This addendum addresses the issue of a designer or owner having the ability to designate site features for preservation not necessarily designated by the authority with jurisdiction.
  • Addendum cb: This addendum modifies Table D1.1 of Appendix G in ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, to reflect new fenestration orientation requirements made by an earlier addendum.
Contact: Michael Woodford.

Saudi Arabia Continues Push to Develop Minimum Energy Performance Standards for Commercial ACs

Compliant with its previously announced schedule to publish minimum energy performance standards (MEPS) for commercial air conditioners (ACs) in June 2014, Saudi Arabia’s Energy Efficiency Center (SEEC) met on April 2 in Riyadh. Al-Asasyah (trader: Sanyo, Gree Basic, Fuji Electric), Carrier (Samco), Daikin, JCI, Zagzoog (trader), SASO (Saudi Arabia Organization for Standards and Metrology), SKM, Trane, and Taiyo Sussan Co. Ltd. (Fujitsu distributor) attended, along with AHRI. Attendees expressed concern with the current SASO 2663 (MEPS for window room ACs and mini-splits) because of the vagueness of its scope, which does not define “other types” of ACs. SASO’s response was that “other types” would be stricken from the scope and defined more clearly in the upcoming commercial MEPS. The Saudi Energy Efficiency Project (SEEP) is currently considering MEPS values in the ASHRAE 90.1, 2010 edition, but no decisions have been made. The next meeting is April 30 in Riyadh, and will identify testing and rating standards to be cited in the MEPS. AHRI will circulate SEEP’s report of the meeting when it is available. Contact: Jim Walters.

DOE Extends Request for Information Deadline for Commercial Boiler Efficiency Test Procedures
The Department of Energy (DOE) is reopening the comment period for the request for information (RFI) regarding the efficiency test procedures for commercial boilers. The RFI was published in the February 20, 2014, edition of the Federal Register and the initial comment period was supposed to end March 24. However, there were technical difficulties associated with the e-mail address to which those comments were to be submitted and some comments, including AHRI’s, were not accepted by the inbox. Therefore, DOE is allowing comments until April 16 and established a new email address to submit comments: Since DOE did not identify any new issues for the RFI, AHRI does not plan to submit any additional comments. Contact: Frank Stanonik.

AHRI Responds to RFI for Commercial Water Heating Equipment Efficiency Test Procedures
On March 31, AHRI submitted comments responding to the Department of Energy’s (DOE) request for information (RFI) regarding efficiency test procedures for commercial water heating equipment , specifically commercial water heaters and hot water supply boilers. The comments supported changes to update the reference to the 2013 edition of the Z21.10.3 Standard, and use AHRI 1300 as the basis for testing commercial heat pump water heaters. The comments also objected to DOE’s suggestion that a test is needed to evaluate the insulation on unfired storage tanks and recommended that no changes be made to the thermal efficiency test method. Contact: Frank Stanonik.

DOE Issues Final Rule on Energy Conservation Standards for Commercial Refrigeration Equipment
On March 28, the Department of Energy (DOE) issued a final rule on energy conservation standards for commercial refrigeration equipment. The final rule updates the standards that were set by DOE in 2009. Compliance with the amended standards is required by March 27, 2017. The standards, which consist of maximum daily energy consumption values as a function of either refrigerated volume or total display area for various equipment classes, are shown in Table I.1 on pages 17727 and 17728 of the Federal Register notice. Contact: Aniruddh Roy.

Certification Programs and Policy Committee Meets to Discuss Testing Diversification
The Certification Programs and Policy (CP&P) Committee held a teleconference on March 27 to review the Executive Committee’s recent statement on testing diversification. The Executive Committee directed the CP&P Committee and AHRI staff to develop a sustainable certification testing laboratory diversification plan for the Executive Committee’s review and approval by the 2014 AHRI Spring Meeting. The next CP&P Committee meeting will be held on April 17 at AHRI headquarters in Arlington, Va. Contact: Bill Tritsis.

Unitary Small Equipment Committee Reviews AHRI Standard 210/240
On March 26 and 27, AHRI hosted a meeting of the Unitary Small Equipment Engineering Committee’s Technical Committee (USE EC TC) at AHRI headquarters in Arlington, Va., to continue to revise AHRI Standard 210/240, Performance Rating of Unitary Air Conditioning & Air-Source Heat Pump Equipment. The USE EC TC was established to provide the initial review of this standard. Representatives from U.S. Department of Energy, AHRI staff, AHRI member companies, and testing laboratories were in attendance.

ASHRAE Issues Call for Comments – Due April 20
Comments are invited by ASHRAE on the Public Review Drafts of the following ASHRAE standards addenda. The Public Review Drafts can be accessed by visiting ASHRAE’s Standards, Research & Technology/ Public Review Drafts web page and following the instructions to access the online comment database. To obtain a paper copy, contact Stephanie Reiniche.

Addendum a to ANSI/ASHRAE Standard 55-2013, Thermal Environmental Conditions for Human Occupancy. This proposed addendum separates vertical air stratification limits for standing versus seated occupants, because the previous requirement did not distinguish between the two, and would be overly restrictive when applied to standing occupants. This clarification only applies to occupants who are standing still with metabolic rates less than 1.3 met because the entire Section 5.3.4, Local Thermal Discomfort, does not apply above 1.3 met.

Addendum d to ANSI/ASHRAE Standard 62.2-2013, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. This proposed change eliminates gravity or barometric dampers as allowable components of passive makeup air systems for combustion appliances. This change has been proposed because of concerns that such dampers do not reliably open at the low pressures (-1 to -5 Pa) that have the potential to backdraft atmospherically-vented appliances.

ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality
  • Addendum k: This proposed addendum modifies the standard such that laboratory exhaust is assigned a default of Air Class 4, but explicitly allows a responsible EH&S professional to determine that a lower air class is appropriate for particular systems. If they assign a lower air class, then the use of heat wheel energy recovery would be allowed. The SSPC believes that determination of the appropriate air class is best made by a qualified professional on a case-by-case basis.
  • Addendum q: This proposed addendum modifies Section 5.2, Exhaust Duct Location, to clarify requirements by including air classes instead of descriptive language, and modifies the requirements by allowing positively pressurized exhaust ducts inside the space of origin. It also modifies the air class of residential kitchen hoods.
  • Addendum r: This proposed addendum deletes Sections and, and removes an informative note to Section The deleted sections remove potentially confusing language, retaining the essential requirement for DCV as stated in Section The changes remove the assumption that the standard is intended for use only as calculations for code review and not physical operation. Proposed changes to Section 5.9.2 clarify the requirements and extend them to apply under conditions of DCV control operation.
ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance Buildings Except Low-Rise Residential Buildings
  • Addendum bn: This addendum adds a requirement for an automated pre-occupancy outdoor air purge in order to ameliorate indoor contaminant buildup that may occur during extended periods of time during which ventilation systems are off.
  • Addendum bo: This addendum updates the requirements for economizers to reflect requirements in ANSI/ASHRAE/IES 90.1-2013.
  • Addendum bp: This addendum revises language in the exhaust air energy recovery section to reflect requirements in ANSI/ASHRAE/IES Standard 90.1-2013.
  • Addendum bq: This addendum updates the efficiency requirements for Electrical-Operated Unitary Air Conditioners and Condensing Units.
  • Addendum br: The addendum updates the requirements for air and water cooled chillers.
  • Addendum bs: This addendum revises requirements for Single Packaged Vertical Air Conditioners, Single Packaged Vertical Heat Pumps, Room Air Conditioners, and Room Air Conditioner Heat Pumps.
  • Addendum bt: This addendum updates requirements for Gas and Oil Fired Boilers.
  • Addendum bu: This addendum updates requirements for water heating equipment.
  • Addendum bw: This addendum proposes to update the Performance Requirements for Heat Rejection Equipment.
  • Addendum bx: This addendum is intended to revise the existing requirements for addressing moisture in building envelopes to be more stringent and to use largely performance-based design criteria.
  • Addendum by: This addendum proposes changes to provide a higher level of indoor moisture control that is currently required in the standard by addressing air leakage with more stringency that the current requirements.
  • Addendum bz: This addendum replaces an existing requirement in the standard to address outdoor air quality impacts of construction vehicles with a requirement that limits vehicle idling and requires signage.
  • Addendum aj: This independent substantive change (ISC) addresses an issue with the definition of low-emission, hybrid, and electric vehicles that was raised in the first public meeting by replacing the definition with a more appropriate statement in the requirements.
  • Addendum an: This ISC makes changes to Table 7.5.3 based on a comment received during the first public review regarding the values for wood and biomass.
  • Addendum aw: This addendum increases the range of products and materials that are considered and introduce more holistic considerations of supply chain impacts of products via life-cycle assessment.
  • Addendum bv: This addendum adds new requirements for Variable Refrigerant Flow Air Conditioners and Heat Pumps.
