For a 120 square meter house, how many horses is it appropriate to buy an air conditioner? Thank you

3 hp air conditioner will do.

According to the national standard, 1 hp air conditioner is suitable for refrigeration area of 10 15 square meters, 10 19 square meters for horse, 16 26 square meters for horse, 15 30 square meters for horse, 2 horse for 20 37 square meters, 3 horsepower for 30 58 square meters, 5 horsepower for 50 65 square meters, 6 horsepower for 60 70 square meters.

The question is too general, first of all, an air conditioner in a room is a must, depending on your choice of home multi-online, how many split machines? A 2P cabinet machine in the living room is generally enough for home use, and the bedroom is generally silent wall hanging, and the inverter can be considered if the machine is turned on overnight! The bedroom generally depends on the area, no matter how big it is, it is not necessary.

The living room has more than 40 square meters, at least one three-P cabinet machine (70) or more.
