There is a correction at 9:40 in question-5 we got the capacity 8626 in KJ/min., So kindly divide it by 60 to get capacity 144 in KW.

Best video on Physchometric chart ...keep up the good work mate

[rahulchetry]

one of the best videos that i have ever gone through

[tejasbavne]

It was the best video for psychometric chart numerical tomorrow is my exam and i am new to this topic thanx to you sir for teaching us through YouTube.😊

[michaelkenney]

pick 1 language per video. Aside from spot on man.

An air conditioning system using 80% outdoor air and 20% recycled air has the following designed conc

Indoor: 24°CDBT, 60% RH

Outdoor: 32°C; 15g/kg water

Sensitive heat gain 48kW

Latent heat gain 16kW

Air leaves the cooling coil saturated and is blown at 16°C DBT

236

(1

A) Answer the following questions

1. Give a synoptic air flow diagram of the described system

2. Extract the characteristics (DBT, WBT, H, RH, w, v) of both the internal and external airs fr psychrometric chart.

3. Calculate the mass flow rate of;

a. The supplied air

b. The recycled air

c. The outdoor air

4. Find the characteristics (DBT, WBT, H, RH, w, v) of the air at the inlet of the coiling coil

5. If the by-pass factor of the cooling coil is 0.15, deduce the value of the contact factor.

6. Determine the surface temperature of the cooling coil.

7. Calculate the sensible and latent loads on the cooling coil.

8. Deduce the sensible heat factor (SHF).

9. Calculate the power of the cooling coil.

1:59 Pv is coming out to be 0.0078 bar. By mistakenly you had written it 0.07926bar.

By the way best video I saw for this topic. Thanks 👍🏻
