If my living room is 200 square feet, please advise which type of air-conditioner we should choose?
We need to estimate the cooling demand in the environment, please refer the following items:
- We can choose according to the room size：
80 square feet before : 7,510 BTU/h
80 ~ 100 square feet : 9,010 BTU/h
100 ~ 150 square feet : 13,145 BTU/h
150 ~ 200 square feet : 17,070 BTU/h
200 ~ 250 square feet : 21,000 BTU/h or above
It will be wasted energy if we use oversized cooling capacity.
(Hitachi DC Inverter allows a room to reach the required temperature more rapidly and more efficiently. Inverter Technology also eliminates the incessant use of the start-stop mechanism often required to maintain consistent levels of temperature. Rather than starting the motor up and stopping it when the room temperature is reached. Hitachi inverters adjust (increase/decrease) the speed of the compressor to an energy saving mode in order to maintain the desired temperature. So that it can be power saving, comfortable and environmental friendly. )
- Number of people in the room
- Height of the ceiling
- Corner of the corridor
(Hitachi's air conditioner has 2 Air Windows in Left & Right and Auto Swing of
Deflectors. So that the cooling air can be delivered widely and evenly. We can
enjoy fresh and cool everywhere in the room. )
- Given-off heat items in the room (E.g. light bulb, refrigerator, television and so on)
- Direction of the room (E.g. West side)
When you purchase the air conditioners, you need to decide according to its environment and your needs, you can consult the air-conditioning professional when you are selecting.
