Prepared for the guidance of architects, consulting engineers and mechanical contractors. Part I -General A. Product Specification 1. Energy Recovery Ventilator(ERV)shall be a packaged unit as manufactured by RenewAire and shall transfer both sensible and latent energy using static plate core technology. B. Quality Assurance 1. The energy recovery cores used in these products shall be third party Certified by AHRI under its Standard 1060 for Energy Recovery Ventilators.AHRI published certifications shall confirm manufacturer's published performance for airflow,static pressure,temperature and total effectiveness, purge air(OACF)and exhaust air leakage(EATR). Products that are not currently AHRI Certified will not be accepted. OACF shall be no more than 1.02 and EATR shall be at 0%against balanced airflow. 2. Manufacturer shall be able to provide evidence of independent testing of the core by Underwriters Laboratory (UL),verifying a maximum flame spread index(FSI)of 25 and a maximum smoke developed index(SDI)of 50 thereby meeting NFPA 90A and NFPA 908 requirements for materials in a compartment handling air intended for circulation through a duct system.The method of test shall be UL Standard 723. 3. Unit shall be Listed under UUETL 1812 Standard for Ducted Air to Air Heat Exchangers and comply with CSA Standard 22.2(except HE6X and HEBX).Some exceptions to UL Listing may apply. Units intended for"Outdoor Use"shall be listed using the specific UL requirements for rain penetration,corrosion protection and seal durability and shall be so labeled. 4. The ERV core shall be warranted to be free of manufacturing defects and to retain its functional characteristics, under drcumstances of normal use,for a period of ten years from the date of purchase.The balance-of-unit shall be warranted to be free of manufacturing defects and to retain its functional characteristics,under circumstances of normal use,for a period of two years from the date of purchase. Part II— Performance A. Energy Transfer The ERV shall be capable of transferring both sensible and latent energy between airstreams. Latent energy transfer shall be accomplished by direct water vapor transfer from one air stream to the other, without exposing transfer media in succeeding cycles directly to the exhaust air and then to the fresh air. B. Passive Frost Control The ERV core shall perform without condensing or frosting under normal operating conditions(defined as outside temperatures above-10°F and inside relative humidity below 40%). Occasional more extreme conditions shall not affect the usual function, performance or durability of the core. No condensate drains will be allowed. C. Continuous Ventilation Unit shall have the capacity to operate continuously without the need for bypass, recirculation, pre-heaters, or defrost cycles under normal operating conditions. D. Positive Airstream Separation Water vapor transfer shall be through molecular transport by hydroscopic resin and shall not be accomplished by "porous plate" mechanisms. Exhaust and fresh airstreams shall travel at all times in separate passages, and airstreams shall not mix. No metal separators or metal core material shall be acceptable. E. Laminar Flow Airflow through the ERV core shall be laminar over the products entire operating airflow range, avoiding deposition of particulates on the interior of the energy exchange plate material. i1 L O CC vuiN`PRODUCT DEVELOPMENT SPECIFICATIONS ARE SUBJECT To CHANGE VV!THOUT NO ICE.
