What size room does the Hisense AP0822CW1W cool?

8,150 BTU of real cooling (SACC) suits about 250 to 350 sq ft with normal sun and two people (about 225-315 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.

How many watts does the Hisense AP0822CW1W use, and what does it cost to run?

About 994 watts at full power (8,150 BTU/h divided by its CEER of 8.2), roughly 8.6 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $134, which is $14 less than the typical certified 8,000 BTU portable unit ($148). Its CEER beats 85% of the 710 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 92% of the certified 8,000 BTU models have one hose, with a median of 7.3 CEER. The top-ranked Hisense HIAP0825TWD has two hoses and 13.5 CEER.

Do I have to empty the Hisense AP0822CW1W?

Usually not. It evaporates the water it removes and sends it out through the exhaust hose. In very humid weather the pan can still fill, and most units then stop and ask to be drained, so keep a drain hose or a bucket handy.

Can the Hisense AP0822CW1W also heat the room?

No, it only cools. 146 of the 710 certified 8,000 BTU portable models can also heat if you want one unit for the year.

Is the Hisense AP0822CW1W as efficient as a window air conditioner?

No. The 33 ENERGY STAR certified window units that cool about as much (within 15% of 8,150 BTU) have a median CEER of 15.1, against 8.2 here, and the best reach 17.0. At 750 hours a year a window unit with that median would cost about $73, $61 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.

8,150 BTU (SACC) single-hose portable air conditioner

Hisense AP0822CW1W

Very good efficiency for its size: a CEER of 8.2 beats 85% of the certified 8,000 BTU portable air conditioners.

The Hisense AP0822CW1W delivers 8,150 BTU of real cooling (SACC), enough for about 250-350 sq ft, draws about 994 watts and costs about $134 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $73 a year.

CEER: 8.2 Combined efficiency, higher is better

Real cooling: 8,150 BTU/h (SACC)For about 250-350 sq ft
Energy use: 745 kWh/yrAbout 994 W, at 750 hours a year
Design: One hose Uses room air for its condenser

A good fit if…

You want low bills - its CEER beats 85% of the 710 certified 8,000 BTU portable models.
You do not want to empty a bucket - it evaporates the water and sends it out through the hose in normal weather.

Think twice if…

You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.
You also need heat - it cools only.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Hisense AP0822CW1W.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.
