Dehumidifier for pool room help
Hello all 
Working on a quote for a new system for a customers pool room. Be our first pool design, appreciate any help. Supplier quoted us a Desert Aire LC-02 dehumidifier, package system heating, cooling, and dehumidification $ + just for the equipment or option 2 a NuAir600 HRV system around $, and then we install a ductless split.
HUGE price difference obviously, operating costs the same. So will ither system do the job? Any help on this pool design system greatly appreciated

If you mean indoor pool..Desert Aire.
-
How many sqft. of water and the climate?

Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"

Yes indoor pool. Why Desert Aire? I'm wanting to know why, and is Desert Aire a better system? Will a HRV and a ductless work?
-
Definitely take a serious look at this.

If you can't fix it with JB Weld, Duct Tape, and Ty Wire it has to be replaced.

If less than a 1,000 sqft of pool surface consider the Hi- E Dry Vehere pool dehumdifier. It is the highest efficiency pool dehumidifier at 6 lbs. of dehumdification per KWH.

A pool room is a very corrosive environment. Just anything won't work. I've seen the plating eaten off faucets. I'd question the mini-split coil holding up. Anyone had experience with this?

Most likely would fall to peices fast in a closed in pool room.
I have a standard Carrier RTU someone put in for the pool room at a fitness club. The unit is a couple yeas old. This past summer the blower motor mount broke down to the point that the entire motor broke loose and went bouncing around the blower compartment while it was still running. I got it running, but there's not much left of the inside of the unit. It'll be replaced this winter.

The chlorine from the pool will eat a system up. What equipment do you have dealership with? Talk to them. They may have options for that enviroment. I know the equipment we sell on the hvac side can build about anything... but you HAVE to let them know the enviroment conditions.

I can't fix it if it won't stay broke..

If you use adequate exhaust ventilation to maintain low CL2 levels inside the space, equipment will not corrode.

In that case you have to add in the extra load of the make up air for the exhausted air.
If that is the case, why not just install a MUA unit that can cool the incoming air that replaces the exhausted air? Would be no different that a commercial kitchen MUA unit and then the chlorine wouldn't be a problem.

Create a very close relationship with the pool dehumidifier that you have selected. Then follow their design advice to the "T" including and especially a sealed vapor barrier. This will relieve you somewhat of some of the liability when and if things go wrong..and they will.
A specialty built indoor pool room dehumidifier/heat pump with secondary pool room heat is a completely different machine then mini splits, which will not last nor will they do the job, and the inner workings of the specialty system will contain coating/materials made for the pool room environment.
You mention no cause as to primary pool water heat from a boiler of from the pool dehumidifier. Different systems have different priorities. There are system that are designed to heat the pool water while dehumidifying. And there are systems that only heat the water while in the dehumidification mode. You need to plan for that.
Analyze all the different makes available. All have their pluses and minuses. None are really "the best on the market" simply because many are installed incorrectly. With the A/C function you also have another layer of complexity. The owners need to known of the additional install cost and operational costs.
In your area of the country the optional A/C mode is not always necessary.

The idea behind specific pool units is to not introduce an excessive amount of OSA. The often drier air increases evaporation and in turn lowers pool water temp and brings on the heater which increases evaporation and on and on.
Before pool units were available the pool rooms used 100% OSA and cost enormous bucks to operate.
I remember an architect that had a design to introduce indoor pool air to the house for the humidity. Within six months the chrome was coming off the faucets.

Delta t good advice as usual. I would also add, maintenance on both the pool and the equipment needs to be followed. I have seen so called built up / homemade pool dehumidifiers, that in a very short period had destroyed the pool room. Are they planning on using a cover on the water surface when not in use?
-
I'm Working on a pool room unit anyone know where to find info or about the company tempmaster?
-
That system, most likely, is not a true pool room application but one made to act like one I'm betting. There was a company manufacturer called tempmaster that is now Wattmaster but has nothing to do with pool room systems. Pictures or application details would be interesting.

Why not a dry-0-tron by dectron

It is a 27 year old pool room unit just spoke to my guy at water & energy. Climatemaster started as temp master. Found iom in his old files. I should be good now.

Your natatorium should be designed as a system. A properly designed system will not only protect your building but will actually save you money. Most poorly designed, and or maintained pool rooms will destroy not only the equipment, but the building itself.
A Dectron unit properly designed and installed will actually save money because 100% of the enrgy recovered from the pool evaporation can and should be used to heat the pool, instead of being wasted to the outdoor ambient through an air cooled condenser.
