What size room does the Foshan Hanyang HYAC-TG7 cool?

4,150 BTU of real cooling (SACC) suits about 50 to 100 sq ft with normal sun and two people (about 45-90 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 Foshan Hanyang HYAC-TG7 use, and what does it cost to run?

About 310 watts at full power (4,150 BTU/h divided by its CEER of 13.4), roughly 2.7 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $42, which is $67 less than the typical certified 5,000 BTU or less portable unit ($109). Its CEER beats 100% of the 461 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 100% of the certified 5,000 BTU or less models have one hose, with a median of 6.2 CEER. The top-ranked Foshan Hanyang HYAC-TG7 reaches 13.4 CEER.

Do I have to empty the Foshan Hanyang HYAC-TG7?

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 Foshan Hanyang HYAC-TG7 also heat the room?

No, it only cools. 6 of the 461 certified 5,000 BTU or less portable models can also heat if you want one unit for the year.

4,150 BTU (SACC) single-hose portable air conditioner

Foshan Hanyang HYAC-TG7

Excellent efficiency for its size: a CEER of 13.4 beats 100% of the certified 5,000 BTU or less portable air conditioners.

The Foshan Hanyang HYAC-TG7 delivers 4,150 BTU of real cooling (SACC), enough for about 50-100 sq ft, draws about 310 watts and costs about $42 a year to run at typical U.S. use and prices.

CEER: 13.4 Combined efficiency, higher is better
Excellent · beats 100%
Real cooling: 4,150 BTU/h (SACC)For about 50-100 sq ft
Energy use: 232 kWh/yrAbout 310 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 100% of the 461 certified 5,000 BTU or less 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.
You need to cool more than a very small room - this size covers about 100-150 sq ft at most.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Foshan Hanyang HYAC-TG7.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.

Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
