Desiccant Dehumidifiers

Postby nielex » Thu Jun 18, 2015 8:57 pm

Dear DB-Team!

In some applications the chilled water temperature is not cold enough to meet the latent load. With a chilled water setpoint of 12 °C it is not possible to accomplish much humidity control with a water coil. And so I would to try using additional dehumidifiaction with a desiccant humidifier.

There are any options to use desiccant dehumidifiers in DB?
In case there are no possibilities to use dehumidifiers, there are any
thoughts to implement dehumidifiers objects?

Thanks for your answers.

Regards, Alex

Stand-alone Dehumidifier: Is this achievable with a VRF or heatpump unit?

Dehumidifier:Desiccant:NoFans is an e+ object.

Desiccant cooling/dehum systems. have been on the development list since
25/10/2012. As most of the items on that list are already here, it would make sense to ask DB where it is on the priority list at the moment.

Hi Alex,

Thank you for the reminder.

The Desiccant dehumidification feature is on our Development Priority list.
Hopefully it will be implemented later this year.

Hello Luis,

thanks for you answer. Something bad that still there is no desiccant dehumidification since 2012. May be it is possible to give them some more priority, you see some requests have arrived.

Hi Alex,

With all the recent work needed to prepare the new v4.7 release and V5.0 beta, I'm afraid that there isn't any new developments yet on the implementation of Desicant dehumidification in DesignBuilder and neither when it would be made available.

What I can say is that this HVAC system is on top of the priority list for new HVAC systems.

Sorry for not being able to commit to a specific date.

BR,
Luis

Hi

Could you give me an update when dessicant dehum will be introduced into DB ?

It is undoubtedly important component and I'm going to use it very often in my simulations.

Thanks,
Maciej

Hi Maciej,

I'm afraid that the Desicant dehumidification system has not been implemented yet in DesignBuilder v5.2.
Hopefully it will be available in future versions.

LFS
