13 5 square meters of master bedroom, the window faces east, is it enough to use 1P air conditioning

If you think about it in terms of comfort. The above should be preferred.

If you go to bed at night. It is also more comfortable and saves electricity.

If it's me. I will choose the larger or above. Because the cooling is fast and it is easy to shut down.

In this way, under normal circumstances, a horse machine will do. As for whether to save electricity or personal living habits, some people turn on the temperature is relatively low, so it is not much power saving.

Load it to cool down faster.

It depends on the sealing and insulation conditions of the room, if the conditions are good, just use air conditioning for summer refrigeration, and buy a horse air conditioner with a cooling capacity of 2500W or a large air conditioner with a cooling capacity of 2600-2800W. However, if the sealing and thermal insulation conditions are general, and heating is needed in winter, and a horse air conditioner is small, it is best to buy a horse air conditioner with a cooling capacity of 3200W or a horse air conditioner with a cooling capacity of 3500W.

Of course, the air conditioner of the horse is definitely more expensive than the air conditioner of the horse, but the cooling and heating speed is fast, the indoor temperature regulation effect is good, and the comfort is also good.

First of all, the higher the P number, the more electricity is consumed. According to the area of your home, the inverter is enough. Of course, if you want to read a cold and heated book faster and with better results, then choose it.

But no matter how you choose, it is recommended that you choose the inverter fluorine-free, because now at least 90% of users choose the inverter fluorine-free, which saves electricity, has low noise, fast refrigeration and heating speed, good constant temperature effect, and will not be like the traditional fixed-speed air conditioner to start and shut down frequently.
