The efficiencies and test procedures for both open and closed circuit cooling towers are not applicable to hybrid cooling towers that contain a <br /> combination of wet and dry heat exchange sections. <br /> b. For purposes of this table,open circuit cooling tower performance is defined as the water flow rating ofthe tower at the thermal rating condition listed <br /> in Table 403.2.3(8)divided by the fan nameplate rated motor power. <br /> C. For purposes of this table,closed circuit cooling tower performance is defined as the water flow rating ofthe tower at the thermal rating condition listed <br /> in Table 403.2.3(8)divided by the sum of the fan nameplate rated motor power and the spray pump nameplate rated motor power. <br /> d. For purposes of this table,air-cooled condenser performance is defined as the heat rejected from the refrigerant divided by the fan nameplate rated <br /> motor power. <br /> e. Chapter 6 ofthe referenced standard contains a complete specification ofthe referenced test procedure,including the referenced year version ofthe test <br /> procedure. <br /> f. Where a certification program exists for a covered product,and it includes provisions for verification and challenge of equipment efficiency ratings, <br /> then the product shall be listed in the certification program,or,if a certification program exists for a covered product,and it includes provisions for <br /> verification and challenge of equipment efficiency ratings,but the product is not listed in the existing certification program,the ratings shall be verified <br /> by an independent laboratory test report. <br /> g. Cooling towers shall comply with the minimum efficiency listed in the table for that specific type of tower with the capacity effect of any <br /> project-specific accessories and/or options included in the capacity of the cooling tower. <br /> h. For purposes of this table,evaporative condenser performance is defined as the heat rejected at the specified rating condition in the table,divided by the <br /> sum of the fan motor nameplate power and the integral spray pump nameplate power. <br /> i. Requirements for evaporative condensers are listed with ammonia(R-717)and R-507A as test fluids in this table.Evaporative condensers intended for <br /> use with halocarbon refrigerants other than R-507A must meet the minimum efficiency requirements listed above with R-507A as the test fluid. <br /> 2015 Washington State Energy Code CE-45 <br />
