Because my previous Aircon was broken last month so I started to survey new Aircon for my liviing room. My original plan was to buy Hitachi top model RAS63NJF but it was shortage due to Renesas IC shortage so I bought Panasonic RX63GHA2. It’s cold and warm funtion together I think the warm funtion can also use in 5 days a year in Taiwan.
Why I would like to write this article for Aircon? Because it’s too many detail items need to check not only the Aircon spec but also your original decoration, power line and refrigerant pipe.
My old model is also Panasonic 63kw so I plan to buy the same one but the master come to my home to see the old refrigerant pipe, it’s 2cm/5cm so he suggests me to buy RX71GHA2. Then I order RX71 to instead but when the inside machine arrive in my living room the master measure the decoration of my space, it can‘t fit in, my space only 120cm but RX71 indoor machine is 128cm......I was totally can‘t understand what‘s going on now. Then he said you can buy the RX63 back, the size is 108cm but the Aircon refrigerant pipe is 2cm/4cm we need to use transfer pipe, some people said it propably will lose refrigerant someday but I don‘t have choice becasue I don‘t want to change my decoration.
After 2 days the Aircon is ready but I found the temperature can‘t go down due to the fitting space is too small and the new RX63 design will occupie the return air space so I need to modify my decoration at the end.
So the conculusion is here. Before you buy an Aircon.
- Make sure the power line 2 cores or 3 cores
- Check the refrigerant pipe size, my living room old one is 2cm/5cm
- Measure the indoor machine size
- Check return air space of your decoration, here is the principe of return air
