In this video we will be learning how to calculate the cooling load for a cold room. We start at the basics first to understand the purpose of a cold room and then move on to understand the heat sources that form the cooling load and then we finish the video by using a worked example for a simplified cooling load calculation.

excellent explanation, based on this which of the AC system components contributes most to the thermal capacity of the system, in other words, say we need to upgrade a standard car SUV factory AC , to be able to handle blowing 42 degree F during extended exploration in extreme middle east desert heat in excess of 130 F , what do we upgrade in order of priority and , how do we measure the overall additional capacity?

At the time stamp 5:48 your calculation for walls and roof are off. When you add up the walls and roof you get 118m sq not 113m sq. It is only a difference of .97Wh/d when you figure the equation. Would that small of a difference make any issues arise down the line?

@eastlandgin 4 года назад

Medium temperature refrigeration maintaining box temperature of 35 to 38F degrees have evaporator fan motors that run 24hrs per day when set point is satisfied and compressor is off to help defrost evaporator and for air circulation.

@zahernasserkarahasan1003 Год назад

why we take into account the rated power of the equipment ? Like the power of the fan is the responsible for moving the fan by a specific torque so , i see that the energy (from the power given by time) to move the fan cannot all be converted to a heat load (or heat generation) as the fan would not have the energy to move I believe that there is some of heating in the process but with a ratio please give me an answer as it is so confusing to me I almost forgot, thank you for this great video

Sir, in Temp out - Temp in, how can we subtract if Temp out is 33celsius minus to -28celsius? Thank you very much

@Nightbow9 4 года назад

Just do the subtraction: 33-(-28)=61 The total temperature difference (delta T) is what we need.

@Nightbow9 4 года назад

Great video, nicely done :) However, the fans' heat load calculation is not correct. You count the 200 W of total electricity consumption as heat. This is true for a heater: 200 W electricity will turn into 200 W heat. That's 100% efficiency, as heating is the purpose of a heater. The electric motor in the fan has an efficiency of ca. 70-80%, so 30-20% of the electricity intake dissipates as heat. Therefore in the formula the 200 W needs to be multiplied by 0.2-0.3, so the 200 W fan will generate only ca. 40-60 W heat.

@myselfnegative4290 3 года назад

Dont forget that movement energy of air taken from fan is also heat. So 200W heat load is no wrong at all

@shubhamsaxena9976 5 лет назад

In this example we assumed that 4000 kg of apple changes daily from a total of 20K so 16K still be there untouched. In such case this cold storage should work 24 hours per day but in the end you took 14 hours/day working . Is it just assumed or there is reason which i could not understand

@taikonot 5 лет назад

every heating load is calculated for 24 hrs, but evaporator is assumed to work 14 hrs in a day.

@kdmq 5 лет назад

Does your factor of energy per cubic meter of air (2 kJ m^3 / deg C) account for latent cooling as well as sensible cooling? The value of the heat capacity times temperature difference (sensible cooling) rarely accounts for the full effect of air infiltration. If you want to calculate based on both sensible and latent cooling, a psychrometric chart is the way to go. When I say latent cooling, this is not to be confused with the freezing of the fruits, which I am aware is not present in this calculation. I am referring to the humidity difference between the air outside and the air inside. Basically the refrigeration system will have to condense large amounts of water that enter the unit as the door is opened, which costs energy.

@ymengineer7200 4 года назад

I'm very delighted to meet your youtube channel. Although i got a question that i still think about. I've seen your video about the cold storage calculation: youtu.be/0gv2tJf. You've said that the runtime of the refrigeration unit is set up to 14 hours, but what happens to the temperature of storage food 🍏after the 14 hours. I assume that the temperature is going to drop of the food. So isn't the refidgarator system not 24 hours working?

@kamozoren 8 месяцев назад

Very helpful. One remark: for "Internal load" - people calculation, it should be 2 people x 4 hours x 270W / 1000. not 270W/h which is a meaningless notion. You have either Watt(power) or Watt x h(energy). Try dimension analysis on your equation: people x hours/day x w/hour = w/d. Which is again, meaningless.
