small cold room evaporator design

[lana]

Dear Sir,

Thank you very much for your valuable guidelines.

I have arrived at heat load considering
1 wall transimission load
2 Air change ( Infilteration) load
3 product load ( sensible,latent,respiration)
4 electrical and occupancy load.

But for given load how to arrive to surface area ( Primary and secondary) and air flow desired which will keep RH 90% and desired temp between +5 to +10 degree celcius.

I will be grateful for your help

Thanks Sunil Bhat

Hi there,

You must either know the air cooler design or use the evaporator manufacturer's catalogs.
Cold room evaporator is selected by :
evaporating temperature, capacity, temperature difference

For high RH you have to select an evaporator with low TD, like 5°C.

Cheers
