This tool calculates the average power/heat load of cabinets in a Cold Air-Containment Aisle. It may also be used to calculate the air flow through raised floor vent grills.
|
It takes in consideration the following parameters:
- Inside and Outside air temperature
- Total air Volume that go through the cabinets
- Number of cabinets
|
|
|
Air Temperature (C)
|
|
Temperature inside the POD cold Aisle. Tipicaly aprox. same as out of CRAC.
|
|
Out (room) Air Temperature (C)
|
|
Temperature outside, at the hot Aisle. Tipicaly aprox. same as return to CRAC.
|
|
Total Air Volume (m3/h)
|
|
Total volume of air pushed by the CRAC equipment to the cold Aisle.
|
|
NOTE: Heat Absorbtion is calculated with the temperature variation on the quantity of air (volume).
|
|
|
Number of Grids Quantity of floor vented grids where air passes through.
|
|
Air Volume / Grid (m3/h): Volume of Air passing through a grid / hour.
|
|
Grid open Area (%): Larger opening area streamline the air flow.
|
|
Air Speed Grid (Km/h): High air speed is noisy and less efficient (needs more energy).
|
|
Air Speed Grid (m/s): High air speed is noisy and less efficient (needs more energy).
|
|
Heat Absorbed (Kw)
|
|
Calculation based on temperature increase and quantity of air flowing through the cabinets.
|
|
Number of Cabinets
|
|
Number of cabinets in the POD
|
|
Actual Load / Cabinet (Kw)
|
|
Actual Power / heat load per cabinet based on the cooling and ventilation data.
