Room volumes up to the manufacturer-published 90 m³ limit needing higher output than the EM90 in the same footprint, provided the room calculation and a safe outdoor exhaust route support the choice.

Who this model may suit—and the main trade-off
The compressor remains in the room. Compare the published 47–50 dB sound evidence, window fit and hose route before treating the BTU rating as a complete answer.
Regular quieter cooling or several rooms matter more than portability; compare a professionally designed split system before buying multiple portable units.

Directly comparable: The same defined field is present in the verified product record.How we compare this model
Portable-v1.0 compares verified specifications against fixed portable-air-conditioner category benchmarks. The internal comparison covers output per rated watt (35), maximum noise (25), weight (15), warranty (10) and verified features (15).
Capacity itself earns no points because the right BTU depends on your room. This is not an efficiency label, product review or laboratory test, and it does not include price or affiliate value.

What to know about the De'Longhi PACEM93K.1SILENT
CoolCompare has organised the manufacturer-published information below. It is not a hands-on review or a laboratory result.
A 10,500 BTU portable air conditioner with cooling, fan and dehumidifier operation.
De'Longhi publishes 10,500 BTU cooling output, 1,000 W input, a 47–50 dB sound-pressure range and suitability for room volumes up to 90 m³. The official UK page also states 400 m³/h maximum airflow, 50 litres/day moisture removal, energy class A, R290 refrigerant, three fan speeds, a 24-hour timer and an included window kit. The direct page showed the model out of stock when checked.

Features and practical meaning
10,500 BTU/h cooling
Published cooling capacity. Use the room-fit result rather than capacity alone, especially for sunny, open-plan or poorly insulated rooms.
47–50 dB published sound
Compare the stated measurement with other models on the same basis. A portable compressor remains inside the room.
1,000 W rated input
This verified input is the starting point for the running-cost calculator. Real consumption can vary as the compressor cycles.
Outdoor exhaust required
The published exhaust-hose length is 1.25 m. Hot air must be vented outside without extending or sharply bending the hose beyond manufacturer limits.
Window kit listed as included
Check that the supplied parts match your UK window opening before ordering.
26.5 kg unit weight
Check stairs, thresholds, storage space and the route between rooms. Castors do not remove the need to move the unit safely.
Dehumidifier mode listed
This mode can remove moisture, but published litres-per-day figures and drainage arrangements should be checked before choosing it for dedicated damp control.

Portable-unit setup matters
Vent hot air outside, keep the exhaust hose within the manufacturer’s permitted arrangement and seal gaps around the window kit. Poor venting can return warm outside air to the room and reduce useful cooling.

Frequently asked questions
What room size is the De'Longhi PACEM93K.1SILENT suitable for?
The published recommendation represented in the CoolCompare catalogue is Up to 90 m³. Actual cooling demand also depends on ceiling height, insulation, glazing, sun exposure and internal heat, so use the BTU calculator before choosing.
How noisy is the De'Longhi PACEM93K.1SILENT?
The reviewed source publishes 47–50 dB. Published sound figures are useful for comparing models only when their measurement context is compatible; room acoustics, fan mode and distance affect what you hear.
How much electricity does this portable air conditioner use?
Its verified rated input is 1000 W. Rated input is not a promise of constant consumption because compressors can cycle. Use your electricity tariff and expected hours in the running-cost calculator for a transparent maximum-input scenario.
Does a portable air conditioner need to be vented outside?
Yes. A compressor-based portable air conditioner must discharge hot air outside through its exhaust hose. Keep the hose as short and straight as the manufacturer allows and seal the window opening; never extend or alter it contrary to the manual.
