Air conditioning for the garden room

Why does a garden room get so hot or cold?

A garden room or conservatory is made largely of glass. That lets in a lot of daylight, but also creates a strong greenhouse effect. Sunlight enters through the glass and the heat stays trapped. On a sunny day the temperature in a garden room quickly rises above 30 degrees, even in spring and autumn.

In winter it works the other way round. Glass insulates less well than an ordinary wall, so the space cools down quickly. As a result, many garden rooms are only really pleasant to sit in for a few months a year. A split-unit air conditioner solves both problems: it cools in summer and heats in winter as a heat pump, so you can use the garden room all year round.

Where do you place the air conditioner in the garden room?

In a garden room there is often little solid wall available. The indoor unit is best hung on the wall that adjoins the house or on a solid section of wall in the extension. That way the air conditioner blows the air along the whole length of the room and your view of the garden stays clear.

The outdoor unit is usually placed on the side or rear facade or on a flat roof edge of the extension. Because the garden room adjoins the garden directly, our engineers pay extra attention to the noise of the outdoor unit towards the patio and neighbours. The connecting pipe is neatly hidden along the facade or through the adjoining wall. If there is no earthed socket nearby, our engineers arrange the necessary electrics.

What capacity do I need in the garden room?

Because of the large glass area, a garden room needs more capacity than an ordinary room of the same size. Allow roughly 0.05 to 0.07 kW per cubic metre, depending on the amount of glass, how much sun the room gets and whether the roof is also glass. A garden room of 20 m² with a ceiling height of 2.5 m then needs an air conditioner of around 2.5 to 3.5 kW.

A south-facing garden room with a glass roof quickly calls for a model of 3.5 kW or more. A model that is too small runs at full load all the time and cannot get the room cool on warm days. Our advisers calculate the right capacity free of charge during the survey. Have a look at the available Daikin 2.5 kW air conditioners or 3.5 kW for an idea of the range.

What does air conditioning in the garden room cost?

The price depends on the model, the capacity needed and the options for placement in the extension. Aircobrabant always works with a fixed price including installation, pipework and commissioning, with no surprises afterwards.

Do you also want to cool the living room or another room at the same time? A multi-split system is then more cost-efficient than two separate installations.
