How do you calculate cooling coil size?
Use the equation as stated above:
- Qwater = 500 * GPM (LWT – EWT)
- GPM = Q / 500 * (LWT – EWT)
- Delta T (water) = Q / 500 * GPM.
- Sensible and Latent Cooling.
- Q = The amount of heat transferred to or from the fluid (BTU/hr)
- M = Mass flow rate of the fluid (lb/hr)
- Delta H = The change in enthalpy of the fluid (BTU/lb)
What is the efficiency of the cooling coil?
In case of sensible cooling of air, the coil efficiency is given by 1 – B.P.F.
How do you calculate the condensation rate of a cooling coil?
Multiply the air conditioner’s flow rate, measured in gallons per minute, by the air’s specific humidity, measured in pounds of water per pound of dry air. If 12 gallons flow through the unit per minute, and the air has a specific humidity of 0.0065 pounds of water per pound of dry air: 12 x 0.0065 = 0.078.
What is the bypass factor for cooling coil?
Bypass Factor is part of the total air through the coil which fails to come into contact with the surface of the cooling coil. Apparatus Dew Point (ADP) is the effective surface temperature of the cooling coil.
What is the contact factor for cooling coil if?
ηH = 1 – BPF = 1 – 0.4167 = 0.5833. 10. What is the contact factor for cooling coil, if td1 = 44°C, td2 = 26°C and td3 = 19°C? ηC = 1 – BPF = 1 – 0.28 = 0.72.
How do you calculate cooler efficiency?
Energy Efficiency Ratio (EER) The EER is a measure of the cooling power of an air conditioning system per unit of power consumed. It is calculated by dividing the cooling power provided by an AC per hour by the number of watts of electricity consumed.
What is the rate of condensation?
The rate of condensation can be defined as the number of water vapor molecules that change phase from gas to liquid each second. The rate of condensation depends mainly on the vapor pressure in the space above the liquid surface.
How do you calculate condensation rate?
Calculate the total condensed liquid flow based on the heat load from the process reactor. This is determined by dividing the total heat removed by the system by the latent heat contained in the steam. The calculation is 30,000 / 794, which is 37.8 lb/hr of liquid condensate.
