System example
¶ Heating capacity correction coefficient at the time of frosting / defrosting (For R407C)
Outdoor suction air temp
– 11– 10– 9– 8– 7– 6– 5– 4– 3– 2– 10123456
(CWB, RH85 %)
Correction coefficient 0.97 0.97 0.97 0.96 0.95 0.94 0.91 0.89 0.88 0.87 0.87 0.87 0.88 0.89 0.91 0.92 0.95 1.0
¶ To find out the heating capacity taking into account the frosting / defrosting operation, multiply the capacity given in the
capacity chart with the value in the above table.
¶ The correction coefficients are for outdoor capacity ratio 100 % heating operation.
