Conservatory Air Conditioning Sizing Up And Advice

Sizing up and advice on selecting a conservatory air conditioning unit

How much cooling power is required?

A conservatory has the obvious effect of heating up in the warm weather and being cold when the season is cold, heating up especially when the sun is on it a conservatory, a greenhouse effect. It is advised when calculating the heat load for air conditioning your conservatory, it advised to add 40% to your initial floor calculation of 100 watts / M sq.

Example A:

If your conservatory is 6 metres by 5 metre (30 square meter floor area) then your basic heat load is (30m x 100 Watts) 3000 watts. Adding 40% solar effect and you get a basic heat load for your conservatory air conditioning of 3000 Watts + 40% = 4200Watts. Therefor you require a 4.2Kw / 14000Btu air conditioning unit.

Example B:

If your conservatory is 5 metres by 5 metre (25 square meter floor area) then your basic heat load is (25m x 100 Watts) 2500 watts. Adding 40% solar effect and you get a basic heat load for your conservatory air conditioning of 2500 + 40% = 3000Watts. Therefor you require a 3Kw / 12000Btu air conditioning unit.

Where to place your internal conservatory air conditioning unit:

If you are thinking about air conditioning for your conservatory it all depends were you can site it. A low floor console style mounted unit can be fitted on a dwarf wall of 600mm. A "Through the wall unit" all in one style air conditioning system has NO outdoor unit which makes them ideal for conservatories, an All in one solution where an outdoor unit is not possible or not preferred. The air is exchanged directly through two ducted air grilles at the back of the unit which takes air from outside to cool and expels the hot air through the other. These units are placed on an internal wall and do not need a professional installation as they are pre-gassed and no interconnecting pipe is needed (see examples here). The all in one style unit can be placed at low level or on a dwarf wall, ideal for conservatories.

When a low wall mounted system is not a option or preferred the a high wall mounted system is ideal. These are always split style (indoor and outdoor format) and the hot air is dealt with directly by the internal unit and rejected through the outdoor unit. (see examples here).
