Calculation of actual cooling capacity and power consumption:
Example: CS-F24DTE5 / CU-L24DBE5
•
Calculation of the actual cooling capacity and power consumption for the following cooling conditions;
Indoor temperature of 27/19°C and outdoor temperature of 40°C (Standard condition).
Calculation method
1.
Find the cooling capacity ratio and the power consumption ratio from the cooling capacity graph and power consumption graph for model CS-
F24DTE5 / CU-L24DBE5.
•
The cooling capacity ratio indicate at the intersection between an outdoor unit air inlet temperature of 40°C on the horizontal axis and an
indoor unit air inlet temperature on 27/19°C is 0.95.
•
The cooling power consumption ratio from the same intersection on the power consumption graph is 1.03.
2.
Thus,
•
Actual cooling capacity = cooling capacity ratio x rated cooling capacity = 0.95 x 6.5 = 6.18 (kw).
•
Actual cooling power consumption = cooling power consumption x rated power consumption = 1.03 x 2.45 = 2.52 (kw).
