KAISER PERMANENTE <br />ASC & Clinic (HUB) <br />Everett, WA <br />Site Prep #1 Electrical Service <br />March 18, 2020 <br />Proiect No. 19.05002.00 <br />SECTION 23 05 93 - TESTING, ADJUSTING, AND BALANCING FOR MECHANICAL <br />PART 1-GENERAL <br />1.1 RELATED DOCUMENTS <br />A. Drawings and general provisions of the Contract, including General and Supplementary <br />Conditions and Division 01 Specification Sections, apply to this Section. <br />B. Related Sections include the following: <br />1. Testing and adjusting requirements unique to particular systems and equipment <br />are included in the Sections that specify those systems and equipment. <br />2. Field quality -control testing to verify that workmanship quality for system and <br />equipment installation is specified in system and equipment Sections. <br />1.2 SUMMARY <br />A. This Section includes testing, adjusting, and balancing HVAC systems to produce design <br />objectives, including the following: <br />1. Balancing airflow within distribution systems, including branchesto indicated <br />quantities according to specified tolerances. <br />2. Adjusting total HVAC systems to provide indicated quantities. <br />3. Measuring electrical performance of HVAC equipment. <br />4. Setting quantitative performance of HVAC equipment. <br />5. Verifying that automatic control devices are functioning properly. <br />6. Measuring sound and vibration. <br />7. Reporting results of the activities and procedures specified in this Section. <br />1.3 DEFINITIONS <br />A. Adjust: To regulate fluid flow rate and air patterns at the terminal equipment, such as to <br />modify fan speed or adjust a damper. <br />B. Balance: To proportion flows within the distribution system, including submains, <br />branches, and terminals, according to design quantities. <br />C. Draft: A current of air, when referring to localized effect caused by one or more factors of <br />high air velocity, low ambient temperature, or direction of airflow, whereby more heat is <br />withdrawn from a person's skin than is normally dissipated. <br />D. Procedure: An approach to and execution of a sequence of work operations to yield <br />repeatable results. <br />E. Report Forms: Test data sheets for recording test data in logical order. <br />F. System Effect: A phenomenon that can create undesired or unpredicted conditions that <br />cause reduced capacities in all or part of a system. <br />G. System Effect Factors: Allowances used to calculate a reduction of the performance <br />ratings of a fan when installed under conditions different from those presented when the <br />fan was performance tested. <br />H. Terminal: A point where the controlled medium, such as fluid or energy, enters or leaves <br />the distribution system. <br />TESTING, ADJUSTING, AND BALANCING FOR MECHANICAL 23 05 93 - 1 <br />
