Basic Performance Parameters
Cooling Capacity
Definition: The amount of heat that can be dissipated per unit of time, usually expressed in kW or kcal/h.
Calculation Formula: Cooling Capacity = Heat Load / (Inlet Water Temperature - Outlet Water Temperature).
Flow Rate and Water Temperature Difference
Cooling Water Flow Rate: Unit is m³/h, needs to match cooling capacity, common models such as 10T, 15T represent processing 10/15 tons of water per hour.
Temperature Difference (ΔT): The difference between inlet and outlet water temperatures, directly affecting cooling efficiency, typical range 15-40℃.
Structure and Operating Parameters
Physical Parameters
Dimensions: Including length, width, and height, affecting installation space and floor area.
Weight: The weight of the entire unit (for example: a certain model weighs 500kg), related to transportation and installation conditions.
Fan and Water Pump
Fan Power: Determines heat dissipation efficiency, energy consumption ratio should be ≤0.07kW/(m³/h).
Water Pump Power: Controls cooling water flow rate and pressure, energy consumption ratio ≤0.035kW/(m³/h).
Evaporation and Drift
Evaporation: The amount of water evaporated during operation, unit kg/h or m³/h.
Drift Rate: The proportion of water drifting out, standard requirement ≤0.01%.
Environmental Adaptability Parameters
Noise Level
Measured in decibels (dB), low-noise design meets environmental protection requirements.
Wet-bulb Temperature
Reflects air quality; the lower the wet-bulb temperature, the higher the cooling efficiency.
