Beschreibung
A portable air conditioner has one design flaw that no manufacturer solves: the hot exhaust hose runs through the room it is trying to cool. That hose radiates heat back into the space, and on a warm evening the machine spends part of its capacity undoing its own work.
The Cold Sleeve wraps that hose in an Oxford cloth composite built to isolate heat and resist the abrasion of a hose dragged in and out of a window each season. It fits exhaust hoses of roughly 5.8 to 6 inches in diameter, which covers the common single-hose portable units, and it closes with two straps rather than a zip, so installation needs no tools and no hose removal.
At 150 by 52 centimetres and about 250 grams, it covers the full run of a standard exhaust hose without adding meaningful weight to the assembly. The fabric layer also protects the hose itself, which on most units is a thin foil duct that dents and tears after two summers of being pushed against a window frame.
The result is measurable rather than decorative. Less heat radiating into the room means the compressor cycles less, which means lower consumption and a room that actually reaches the temperature on the dial. It also makes a terrace, a garage or a basement installation look considered instead of temporary.
Cooling a room while heating it through a hose is a solved problem. This is the solution.
What Makes It Different
- ✦Insulating sleeve that reduces heat radiating from the exhaust hose back into the room
- ✦Fits exhaust hoses of roughly 5.8 to 6 inches in diameter
- ✦Oxford cloth composite resists breakage, deformation and abrasion season after season
- ✦Two straps close the wrap, so no tools and no hose removal are needed
- ✦150 by 52 cm coverage for a full standard hose run
- ✦About 250 g, light enough that it does not stress the window kit
- ✦Improves the look of a terrace, garage or basement installation

Where It Earns Its Place
The obvious user is anyone running a single-hose portable air conditioner in a bedroom or living room, where the hose crosses the room and the machine never quite keeps up. It also suits a garage or workshop installation, where the hose is long, the ceiling is low and the heat gain is worst. Renters who cannot fit a split system get the most from it, because they are usually working with the least efficient configuration and the hose is exposed across a whole room. Seasonal storage is easier as well: the sleeve stays on the hose, so the whole assembly goes back in the box covered rather than bare.

Questions Buyers Actually Ask
Q: Will it fit my portable air conditioner?
It fits exhaust hoses of roughly 5.8 to 6 inches in diameter, which is the common size on single-hose portable units. Measure the hose circumference before ordering, since dual-hose and window units use different diameters.
Q: Do I need to remove the hose to fit it?
No. The sleeve wraps around the hose in place and closes with the two supplied straps, so it can be fitted with the unit already in the window.
Q: How much difference does it make?
It reduces the heat the hose radiates back into the room, so the compressor runs less to hold the same temperature. The gain is largest on long exposed runs in a small room, and smallest where the hose is short and already shaded.
Q: Can it be used outdoors?
It is built from Oxford cloth composite and handles a terrace or balcony, but it is not a waterproof cover. Bring it in or cover the unit if rain is expected for days.
Q: Will it make the hose too heavy for the window kit?
At around 250 g the sleeve adds very little. The window plate on most portable units handles it without extra support.
Q: Can I cut it to a shorter length?
The fabric can be trimmed, but the cut edge will fray over time. Fold and strap the surplus instead if the hose run is shorter than the sleeve.
Q: Does it work in winter as well?
Yes. The same layer slows heat loss from a hose used with a heat pump mode, which is why the sleeve is described as seasonal rather than summer-only.
Q: How do I clean it?
Wipe with a damp cloth or brush off dust. Do not machine wash, because the composite layer separates from the outer fabric in agitation.
