To age optimally, wine requires a balance of temperature and humidity.The temperature affects the rate of maturation while the right humidity keeps corks in good shape during the aging process.Heat from the wine cellar is absorbed by the WhisperKOOL system and then discharged into the next room from the rear of the unit.In order to make sure that your wine cellar stays at its ideal temperature and humidity the cooling system operates roughly 75 to 80 percent of the time.

For temperature control the XLT system uses a liquid temperature probe to measure the temperature of the wine rather than the temperature of the air in the cellar which has a few great benefits:

1-the wine is maintained at its ideal temperature

2-the cooling system does not stop and start all the time which helps increase its expected life

3-the unit will run longer during cycles effectively maintaining humidity

It’s important to remember that the XLT series has a 30 degree temperature differential so for example if the desired cellar temperature is 55 degrees the area it is exhausting to should not exceed 85 degrees.So in many cases it will be necessary to install the unit in an interior wall due to warm summer temperatures. 

If an interior installation is required the room to which the unit exhausts must be no smaller than the cellar itself.It is also important to make sure that the cellar is well insulated and vapor sealed to allow the cooling system to operate at an optimum level.

Finally, a great benefit of the WhisperKOOL XLT 3000 and in fact all models in the series is that installation is simple.The unit is designed to be installed through-the-wall and fits between standard wall studs.  There is also a rear flange which means that there is no need to install a support shelf.

Without a doubt the WhisperKOOL 3000 will ensure that your wine collection ages gracefully! 

I have not owned or worked on any Haier products before, so I did some quick research on them and found that they are an appliance manufacturer, not a manufacturer that specializes in air conditioning.  Needless to say, I don’t expect this thing to last for 20 years under heavy usage, but if I can get 10 years out of it and it works as it is supposed to, then I’ll consider it well worth the cost.

The reason that I even considered purchasing a portable air conditioner to begin with is the fact that we are empty nesters and there is just no reason to run the big central unit to cool off the entire house as much as we used to when the kids where here all of the time.  We still have it turned on so that the heat and humidity don’t ruin our stuff, be we can set it to something higher than a comfortable living temperature for the whole house, and now we can use the portable air conditioning for the bedroom so we can sleep comfortably.  If this works out, then we’ll be looking at a couple more units for the den and kitchen.

This particular model comes with separate air intake and air exhast duct ports, and a window adapter.  It can run in 3 modes: cooling, heating, and dehumidifying.  There is an LCD indicator that let you know when the condensation tank becomes full.  There are 3 an speed: low, medium and high.  There is a timer function that goes up to 24 hours that will turn the unit off automatically.  I’m not sure if and when I would ever use that, but it’s one of those “nice to know it’s there” features.  Heat pump included.  Temperature control.  Remote control included, for all of us lazy bastards that can’t get up out of the lazy boy unless it’s to get a frozen pizza or something like that.  It uses R-22 coolant which is not a good thing, but I haven’t seen an portable units that are cost effective that are using Puron yet.  The air filter easily snaps out from in front of the evaporator air intake in the rear.

That’s it.  As I get to know this guy a little better I’ll keep y’all posted.  Wish me luck!

• The overall cooling capability of the unit
• How often the compressor will turn on & off.  “Short-Cycling” prevents dehumidifying
• Factors heavily into the energy efficiency & operating cost
• Maintenance costs over the life of the unit

Strangely enough, the most common problem encountered in existing construction is OVER-SIZED units.  In studies performed by utility companies on the west coast, one found that slightly over 1/2 of the home air conditioners checked were a ton (12,000 Btu/h) or more oversized and another company found the same in 1/3 of the home air conditioners they checked.

Why is this so?  Because the correct method of calculating the optimum size of the unit needed is rather complicated and most contractor use shortcuts to save time.  Either that, or they just don’t know how to do it properly.  MANUAL J is the universally accepted standard. It was jointly developed by the Air Conditioning Contractors of America (ACCA) and the Air-Conditioning and Refrigeration Institute (ARI).  It is a lengthy publication, and rightfully so since it factors in all of the variables that must be considered to properly size home air conditioners.

It doesn’t matter whether or not you are talking about:

• Central Home Air Conditioners
• Window Unit Home Air Conditioners
• Portable Home Air Conditioners

The requirements are the same in order to provide you with the comfort you need while minimizing the operating costs and total cost of ownership over the life of the unit.  Contrary to what your parents may have taught you, the longer that home air conditioners run, the more efficient they are.  Ones that cycle on and off constantly are no dehumidifying the air AND they are eating up your electrical bill.

Our recommendations are:

• Do not try this on your own unless you have an engineering degree, a lot of time to spare, and enjoy reading 200+ page technical manuals -or- can buy or borrow a copy of Home Air Conditioning Software based on the Manual J Standard;
• If you go with a contractor, select one that specializes in Home Air Conditioners;
• Insist on getting a printout from you contractor of the Manual J data they used to calculate the optimum unit size of the home air conditioners.
