List Price: $459.00
Our Price: $459.00
Stay COOL and breathe fresher air with Sunpentown's 7,500 BTU unit. Ideally cools an area up to 200 sq. ft. Effectively improves air circulation in poorly ventilated spaces and maximizes energy efficiency. Manual control is specifically recommended for use in Server rooms. If there's a power failure, unit will automatically turn itself back on when power resumes. Self-Evaporating Technology - during the cooling or heating process, water is extracted from the air into the unit. Most of this water is then recycled and used to cool the cooling coils and make it run more efficiently, cooling as well as energy. Note: Exhaust hose installation required (all standard accessories included).
works well I bought this unit to replace a window AC that is no longer allowed in our condo building. The primary purpose is to dehumidify our entire condo (only 850 square feet), so we are using this unit for a space larger than it is designed to cool. But, even so, it works well and it has a phenomenal Energy Efficiency Ratio (EER) of 12.5, so you get 7500 BTU cooling for only 650 watts of power.
To respond to the previous review that rates this unit poorly, I'd like to go over the points that reviewer mentioned from my perspective...
1)drying the air - this unit will take the relative humidity in our condo down more than enough to make a muggy day comfortable indoors. If we turn the unit on early before the heat of the day, it will maintain the temp in our condo as it drys the air, not bad for a unit designed for a small room.
2)it must be drained of water - true, but most of the water it produces is evaporated over the heat exchanger and sent outside. A small amount of residual water is what you must empty and we find the unit will run for several days continuously before emptying is needed. A light indicates when the water tank is full. The drain is very low as the previous reviewer mentioned, so it is helpful to roll the unit to a stair-step so you have some clearance below it for the water to pour out. This is an inconvenience but unless you have trouble bending over, not a difficulty.
3)it has wheels that are small - yes, it may take effort to roll over a carpet (unit is 60 pounds) but no problem on hardwood floors.
4)hard to move, nothing to grip - haven't found this to be a problem. There are handles (one on each side) and anyone who is able to handle the weight should have no problem. No air conditioner is light and compared to wrestling with a window unit this model is a snap to move.
5)poor window exhaust seal - I don't understand this criticism. The unit comes with panels and a pre-cut hole for the exhaust hose. All fit together tightly to make a tight, rattle-free seal with no duct taping required. The panels allow a fit to any size double hung window.
The unit has two squirrel-cage fans, one for cool air, one for exhaust. The noise they produce is from rushing air, not motor noise so there is no annoying hum or buzz. There are only two fan speeds and they don't differ much. If I had my wish I'd want a slower speed available. The amount of air moved is great. I can sit in a chair twenty feet away from the unit in another room and feel the draft, so I use the unit as a fan when the cooling/dehumidifying isn't needed.
The exhaust hose will expand or contract to fit the length you need to reach the window from the back of the unit. There is a quick disconnect that snaps the hose into the unit, so you can quickly disconnect the hose if you need to move the unit for any reason. The hose screws into the plastic fittings at both ends so it won't pull apart on you.
The exhaust air to the outside is hot. As a result the hose will get warm. That warmth adds to room warmth and you don't want that heat in the room. I recommend wrapping some vinyl backed fiberglas insulation around the exhaust hose to keep the exhaust heat from the room you are cooling.
This unit has ONLY an exhaust hose. Without the intake hose of more expensive models, it must take room air and exhaust it outside. This means warm, humid air will be pulled into the room as a result. This lowers the cooling and dehumidifying efficiency but we haven't noticed this to be a problem.
Poor at drying the air & very cumbersome to move We have the WA-1220M model of this product (virtually identical). If you stand right in front on it, up to about 5 feet away, it's nice. However, it has several drawbacks:
1. It isn't very good at drying the air; evaporation is needed for effective air-conditioning (whether in your car or your home).
2. It must be drained of the water it does pull from the air, and draining the unit is very cumbersome. It comes with a small flexible plastic tube that has to be connected to the rear bottom of the unit; the other end must be lower in order to drain or the unit really does very little and although there's an indicator light that will come on if the unit is quite full of water, it's very rare that the light comes on (and it only does so LONG after the unit has stopped cooling the air). We have taken to wrapping a large towel around the far end of the tube to collect water that drains, but basically you must tilt the heavy unit backwards to try to drain it. This is not particularly effective but it must be done.
3. It has wheels, but it doesn't roll easily (it's hard to push or pull it in a straight line and the wheels are so small even getting over a low rug is difficult.
4. Moving the unit up or down a single step can be accomplished by one person but since the entire unit is made of very smooth, slippery plastic (it has handles but they're very shallow & not helpful), it's more safely accomplished with two people.
5. Consider that this unit, while mobile, sacrifices a good window seal. The large exhaust hose (which pumps the hot air outside) resembles a telescoping dryer hose that easily falls out of the backside of the unit and is awkward to extend evenly. The unit comes with a smallish piece of foam with a cutout hole for the hose. However, you are left with having to find some way to block the rest of whatever window you choose to put the hole into. We use a large carboard box panel and cut a hole out of, then duct-tape the box into the window opening to block out air seepage. As you can imagine, it looks pretty tacky.
