Swimming Pool Air Conditioning Help
Hi all,
We have been asked to install an air conditioning system into a new private residential indoor swimming pool in order to provide cooling in the summer and heating in the winter
we have been told by the builder that the customer isnt having a pool cover and that the client will be maintaining the pool temp at 28C. We have therefore been told that there will be high humidity levels.
we havent installed a system into a swimming pool before and i have chosen a ducted system as we can hide everything above the false ceiling being put in so it looks nice and neat
so i need to know if an a/c system will be ok in a swimming pool environment with high humidity levels and whether or not the chemicals used in a pool will affect / corrode an a/c system as the air is being passed through the system
any advice on this would really help
thanks
paul

Re: Swimming Pool Air Conditioning Help
Installing a 'run of the mill' split system will not be enough to cope with the amount of latent heat being produced within the pool hall atmosphere. The most practical system to install would be a heat pump unit which will be able to dry out the air and keep reliable temperature. Check out a company by the name of Calorex and they will be able to supply you an appropriate system for your environment.

Try looking up Pool Pak on the net.
We at Trane actually reps them also., i just finished doing a calc on an install on an indorr pool. The units are somewhat special, Including partial and full pool water condensers etc. I would not use a residental unit in the install. If I can help you out with a calc send me a note.

Re: Swimming Pool Air Conditioning Help
Id say take all fresh air condition it then put it in the space and vent the old air out.
This way les humidity, les chance of chemical interaction, and cheaper power on the long hual.

Re: Swimming Pool Air Conditioning Help
you need to keep the air temp 2 deg above the water temp to stop excessive water evaporation

Hitachi also offer a service to put most of there kit through an out of house specialist who treat the coils with anti-corrossive agents for special applications. If your going to do the install then maybe have a chat with Hitachi-tap them up for the company who treat the coils, and have this company undertake the same service to kit specifically designed for this environment-not room air conditioners as they'll never cope with the duty.
I worked on a few swimming pools last year. Fairly old kit R-22 based. Used the pool water to disipate condenser heat like a chilled water system only on the discharge side. The evaporator blasted through the ventilation ducts acting as a dehumidifier.
To be honest this was loads of grief. My advice........think carefully about taking the job on, and be sharp with your warranty terms or you'll never hear the end of it!

Re: Swimming Pool Air Conditioning Help
Hiya,
Pools are different from normal rooms. The reason for this is because typically, the control temp is around 30 Deg C or one degree above pool water temp. This is to prevent condensation on building fabric etc.
This means that, for the most part, the cooling needs (if any) can be met by fresh air.
Try looking at a specialist pool unit like Genvex or Calorex etc.
Also, remember that you may have to heat the place to 30 degrees inside when its 22/23/24 etc outside. Very few commercial (heat pump) splits will heat under high indoor AND outdoor coil temps........most say (for heating) not more than 21 outside against 24 inside.
Have fun!

Calorex,
Get them to spec a unit for you, ,job done.
If Calorex is too expensive for the customer, walk away. Its not worth it

Re: Swimming Pool Air Conditioning Help
biggest heat loss from a pool is evaporation.
Dectron invented the system years back. Dehumidify the air, condensate goes back to pool, you can rect the heat to the pool or a remote condenser.
Blanket the windows with the supply air
Keep the space under a slight negative pressure especially in the winter else you will rot your walls outTake the V out of HVAC and you are left with a HAC job

Re: Swimming Pool Air Conditioning Help
Using a textile duct would be a good idea for the air distribution as the duct is non corrosive, so will not react with the chlorine.

Re: Swimming Pool Air Conditioning Help
My query is how do u calculate the load in pool area... how much RH to maintain. I am well versed with HVAC and doing design for past 7 years but yetr to do any pool design. A detailed reply on calculation will be worthwhile.
