The Engineering Mindset plz cover Refrigeration segment Freezer & Cooler

Very important to note that the tonnage leading to 3.5kW is the cooling load, NOT input power. Input power of 1 tonne is approx 1kW ( depending on SEER of machine )

Refrigeration ton (RT) is defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. Notice that the freezing or melting of the ice represents a change-of-state only, which is considered a transfer of latent heat, as opposed to a change in temperature which is a transfer of sensible heat. 1 refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW.

Can't Thank you enough, You help students immensely.

Paul you are amazing!

Excellent!

incredible videos will you make a video on HAP, E-20

Great videos ............ Thanks :) kindly also incorporate the daily working of HVAC design engineers..... Thanks

Great videos!

Hello, what is the relationship between TONs and air flow of a system?

Another good video c/w simple explanation. As an engineer though I do tend to spot errors: for instance BTU/hr x 0.000083 = RT you have made a typo showing BTU/hr as the same unit. Sorry but had to point it out or I would not have slept tonight :)

,,,,,,Btu ton ,refrigeration ,ton capcitey, 1 ton btu, =12000btuhour ,1ton =12000 h ,1btu=552 kalory ,1ton=12000×552=3024000 , ,,,1ton=302400/1000=3024/houer,

Hi may i ask? Is it possible to convert tons of refrigerant directly to mass units? Thank u.

Hey, isn't 1 ton of refrigeration related to the heat of 1000 kg of ice ? I studied it like that. Or both 1000 kg and 907 kg are valid ? Please reply.

I find it curious that the ton, a measure of weight, is used in the Imperial calculations but kg, a measure of mass, is used in the metric calculation.

How do we know the amount of refrigeration required for an area?

Calculate cooling load. Watch our ductwork video to do this

Sir I want to know what is capacity index

I don't understand the question fully. But capacity is the amount it can produce and index is a a measurement of something so I assume this means the measurement of how much cooling it can produce

Dude, you need to spell check your videos. Mistakes everywhere. Otherwise, great videos.
