Configuration problem of Hitachi central air conditioning for 60 square meters small apartment.

Indoor units: 7 1 HRNQ: 7 100 W, 249w/m2 (refrigeration), 8500/298 ().

40hrq: 4300/26 1 (refrigeration), 4900/297 (heating)

25hrnq:2500/227 (refrigeration), 3000/273 (heating) According to this parameter provided by you, I will give you a formula, and you will understand it at a glance: the guest restaurant must use 7 1HRNQ, and the actual cooling capacity of the guest restaurant = 249 * 28.5 = 7096.5W

The master bedroom must use 40HRNQ, and the cooling capacity required for the master bedroom = 261*16.5 = 4306.5w.

RPIZ-25HRNQ must be used in the research, that is, the research cooling capacity =227* 1 1=2497W.

Basically no problem, the external machine 5P, 7 1 is 3p; For 40, you can call it small 2P or large1p. 25 is exactly1p.

I won't give you the heating part because your home is going to do floor heating, but I suggest you choose Daikin or Mitsubishi since you want to do central air conditioning. As for Hitachi, I really beg to differ. Of course, you have your cost budget and your consideration. I wonder how much this air conditioner he made for you costs? One more suggestion. Since you want to be the central system, you must never ignore the auxiliary materials. Otherwise, something goes wrong in the end, which is very troublesome. If it is serious, it needs to be redecorated.
