How is cooling capacity of Ahu calculated?
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.
How do you calculate sensible cooling capacity?
We also learned that the sensible cooling load (hs) is calculated by multiplying the specific heat of air (cp) by the density of air (rho) by the air flow (q) and the temperature differential. SHR is calculated by dividing sensible cooling load by the total cooling load.
How do you calculate cooling cost?
The answer is your annual cost of cooling. For example, if the BTUs of your unit are 36,000, the SEER number is 10.5, your cooling load hours are 600, and your electric rate is . 092, your process would be 36,000 divided by 10.5, or 3,428.57. Multiply 3,428.57 by 600 to equal 2,057,142.80.
How do you calculate sensible cooling?
How is cooling CFM calculated?
How to Calculate the CFM of a Room
- Measure the room’s width and length.
- Multiply the three measurements from step 1 to determine the cubic footage of the room.
- Multiply the cubic volume of the room by the number of times you want the air to turn over or exchange in an hour.
What is cooling sensible capacity?
During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
What will 12000 BTU cool?
A 12000 Btu unit will effectively cool a room with a floor space of 500 to 600 square feet.
What is an ahu in HVAC?
An AHU is an HVAC equipment to provide cold (in this case cooling) and treated (filtered and more) air to a room, space or a building and allow suitable indoor air quality (IAQ) The cooling capacity of an AHU is an acronym in HVAC for air handling unit which is different from cooling tower (CT).
What is a load calculation in Ahu?
A load calculation determines the capacity of AHU, more specifically the capacity of the heating/cooling coil. The thermal load is estimated in units of BTUs.
How does the cooling of the Ahu of a device work?
The cooling is achieved by evaporative cooling. Assuming your query is referring to the AHU.
What is the Ahu inlet for?
AHU inlet is same as the “return air from room” / “room air temperature” / “required zone air conditions”. Also, take the below readings at the AHU coil outlet. Coil leaving air temperature will be slightly higher than the coil surface temperature & chilled water outlet temperature.
