Air conditioner for a 30 m² room or kitchen-living area

30 m² is usually a combined kitchen-living room in an apartment or house, sometimes a spacious living room with a dining area. A hob, oven and fridge run here and more people are present at once, so the average table assumption can be too optimistic.

What must be assessed for this area

• Kitchen equipment. Cooking heat is added to the load; especially important if the kitchen is on the south side.
• Unit position. The indoor unit should not be mounted directly above the hob – grease vapour contaminates the heat exchanger and filters.
• Glass doors to a terrace. A large glazed area increases solar load; a higher window factor applies.
• Number of zones. In an elongated room, two smaller units on a Multi Split system are sometimes more practical.

In the catalogue, the 3.5 kW and 5.0 kW nominal cooling classes are most often considered for this area (e.g. MSZ-LN35VG, MSZ-LN50VG, MSZ-AY50VGK). The specialist makes the final decision.

Preliminary cooling capacity estimate for a 30 m² room

If the air conditioner (an air-to-air heat pump) is also used for heating, a room in energy class C needs a preliminary 1.4–2.0 kW of heating capacity at −23 °C outdoors.

Assumptions: ceiling height 2.7 m, 2 people × 130 W, medium-sized windows, no extra heat-emitting equipment. Formula: Q = A·h·q·f_windows·(1.15 for a top floor) + people·130 W + equipment; range Q…1.2·Q.

Next step

For a more accurate figure, enter the exact ceiling height, window size, number of people and equipment in the air conditioner planner. Before the site visit, prepare photos of the room, a floor plan and a possible outdoor unit location – this shortens coordination and lets the specialist propose the right solution straight away.

This is a preliminary estimate based on the formula of our air conditioner planner; the final capacity and the indoor unit position are confirmed by an EKO2ŠILUMA specialist during a site visit.
