As housing conditions improve and living standards rise, central air conditioning is no longer exclusive to commercial and office spaces; it's now within reach for average consumers to enjoy the comfort it brings. However, central air conditioning is different from standard household air conditioners, requiring design based on the building layout and area, starting with estimating the indoor and outdoor unit capacities. Below, our editor will explain how to choose the indoor unit of a central air conditioning system based on the area.

Determine outdoor unit capacity

For example, in a 105㎡ suite, if the kitchen and bathroom do not require air conditioning, the air conditioning area can be taken as 65% of the total floor area, which is 105㎡ × 65% = 68㎡.

Based on a calculation of 2.5 to 2.8 kW per horsepower, one horsepower corresponds to 10 to 15 square meters. Therefore, the outdoor unit capacity of this suite (calculated at 12 square meters per horsepower) is 68 divided by 12, which equals 5 horsepower.

Determine the indoor unit capacity for each room

To determine the appropriate size of the air conditioner for a 24㎡ living room (with a calculation of 10㎡/horsepower), you would need 2.5 horsepower (since 24÷10=2.5). For the dining room and the master and secondary bedrooms, each at 15㎡, you would require 1 to 1.5 horsepower.

3: Selection Team

Each family's space and户型 vary, as do their budget considerations. Shanghai Quntan's design team will tailor a suitable air conditioning system solution according to your actual needs, taste, and preferences.
