DAIKIN FXFQ80P9 information about water condensation

[boski]

hi everybody ;

I need information about water condensation for daikin FXFQ80P9 indoor unit. There ll be about 1500m3/h air at 35C and with %80 humadity and it ll be cooled for 10C and %50 humadity . My question is how many kg water ll be condensated in 1 hour? Sorry for my English but I ll be glad if someone explain and find me a solution.

Thanks

To calculate kg/hr moisture removal

kg/hr = vol x delta kg/kg x 3600 / specific volume

You need to use a Psychrometric Chart

from your figures - 35C @ 80% and 10C @ 50% the results are

Vol = 0.416m3/s
Delta kg/kg = 0.0256
Sp Vol = (0.806 + 0.914/2) = 0.86

so

kg/hr = 0.416 x 0.0256 x 3600 / 0.86 = 44.57

Looking at the spec sheet for the FXFQ80P9 it will not handle the volume or the humidity
The maximum volume on high speed is 1410m3/hr but more importantly, it is only rated at 9.9kW cooling duty and you need 15kW

What you asking is this:

That is if you have dehumidifier which will dehumidify all new air in one pasage. But, that is not your case.
You have air-conditioner which will cool same air and dehumidify it in multiple pases through it.

This is from tehnical data:
