icyberboom RHKT14030

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the icyberboom RHKT14030.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.

Compared with every DOE-certified portable unit in the same size class (SACC). Each model number counts once. Yearly cost at 750 hours and 18.0¢/kWh.

This unit at each city's cooling hours and state electricity price, against a window unit that cools as much.

What size room does the icyberboom RHKT14030 cool?

9,200 BTU of real cooling (SACC) suits about 300 to 400 sq ft with normal sun and two people (about 270-360 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 icyberboom RHKT14030 use, and what does it cost to run?

About 1211 watts at full power (9,200 BTU/h divided by its CEER of 7.6), roughly 10.5 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $164, which is $7 less than the typical certified 10,000 BTU portable unit ($171). Its CEER beats 0% of the 706 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 78% of the certified 10,000 BTU models have one hose, with a median of 7.9 CEER. The top-ranked Midea MAP12S1TBL has two hoses and 14.7 CEER.

Do I have to empty the icyberboom RHKT14030?

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.

How does the icyberboom RHKT14030 heat?

It has a heating function, but the DOE data records only that it exists, not whether it is a heat pump or an electric element. Ask the maker: a heat pump gives more heat per kWh than a resistance element, which costs the same as any space heater. 200 of the 706 certified 10,000 BTU models can heat.

Is the icyberboom RHKT14030 as efficient as a window air conditioner?

No. The 54 ENERGY STAR certified window units that cool about as much (within 15% of 9,200 BTU) have a median CEER of 15.0, against 7.6 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $83, $81 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.
