laboratory was built in accordance to the AMCA Standard.Most of the products are tested and certified by AMCA Certified Rating Program(CRP),and their catalog ratings are approved by AMCA Internationals staff.All these products and their catalogs are approved to use the AMCA International Certified Ratings Seal.The Certified Rating Seals include:Air Performance,Sound and Fan Efficiency Grade(FEG).注意：1)有些生产厂商的印刷品中有下列类似阐述“按照 AMCA 标准进行测试”，但请注意这与“产品被获准使用 AMCA 国际的认证额定值印章”有本质区别。印有类似语句的印刷品仅仅表明该产品采用AMCA 公布的标准进行测试，但是其测试的数据不会被 AMCA 承认。2)另一个容易引致误会的方面是 AMCA 国际的认证额定值印章与 AMCA 会员证书之间的差异。有些生产厂商会将 AMCA 会员证书印在产品目录上，这容易让人误解为其产品已通过 AMCA 的测试及认证。红白的 AMCA 会员证书仅仅代表其为 AMCA 国际的会员，只有蓝黄色和绿黄色的认证额定值印章，才表明该产品是通过 AMCA 认证额定值程序(CRP)的测试，并被批准使用AMCA 国际的认证额定值印章。如图 1 所示。Note:Some manufacturers have printed the following statement:tested in accordance with AMCA standards in their catalogs.Please note that there are essentially different from the statement of“the products are approved to use the AMCA International Certified Ratings Seal.These manufactures statements mean that their products are tested in accordance with AMCA Standards,but the tested data are not recognized and approved by the AMCA International.Another statement that can easily lead to misunderstanding is the difference between the AMCA Interational Certified Ratings Seal and the AMCA Membership Certificate.Some manufacturers have printed the“AMCA Membership Certificate”in their catalogs.This is misleading to let people believe that their products have tested and certified by AMCA.The“AMCA Membership Certificate”(red and white color)indicates that the manufacturer is a member of the AMCA International only.Only the“AMCA International Certified Ratings Seal”(yellow and green,yellow and blue color)symbols indicates that the products have been tested through the AMCA International Certified Rating Program and have been approved to use the“AMCA International Certified Ratings Seal.(Fig.1)D).亿利达与 AMCA

r/min and the shaft power is 7.47 kW(the motor power is 11 kW).Now the site needs to increase the airflow to 30,000m3/h.Find the new fan speed,static pressure and the shaft power.The maximum fan speed of SYQ630R is 1700 r/min,so it is not a problem for the fan speed to run 1464 r/min.Now,the shaft power is increased to 12.91 kW,so the original 11 kW motor cannot be used,the motor needs to be
