Ps:1.The above correction factors are determined based on the average values of various units. For small units (05~15), multiply by 0.95; for large units (50-200), multiply by 1.08.
2.The above correction factors are approximate values and are for reference only.
Correction under different wind speeds, inlet air temperature, and water temperature conditions:
Actual cooling capacity = Cooling capacity from Table 1 × K1 × K3
Actual water flow = Water flow from Table 1 × K1 × K3
Actual water resistance = Water resistance from Table 1 × K2 × K4
Example: Selecting YG-20 air conditioner, the cooling coil face wind speed is 2.5 m/s. According to Table 1, the cooling capacity is 150.8 kW, water flow is 26.21 m³/h, and water resistance is 14.07 kPa. Determine the actual cooling capacity, water flow, and water resistance when the inlet air dry-bulb temperature is 27°C, wet-bulb temperature is 21°C, inlet water temperature is 7°C, and outlet water temperature is 12°C.
Solution: From Table K1, the correction factor K1 = 1.14. From Table K2, the correction factor K2 = 1.27.
Therefore:
Actual cooling capacity (Q) = Standard condition cooling capacity × K1 = 150.8 × 1.14 = 171.91 kW
Actual water flow (V) = Standard condition water flow × K1 = 26.21 × 1.14 = 29.88 m³/h
Actual water resistance (P) = Standard condition water resistance × K2 = 14.07 × 1.27 = 17.87 kPa
