Hi All,
New to the forum.
I wish to install a triple split air conditioning system in to my house to condition the sitting room and two of the 4 bedrooms that the afternoon & evening sun strikes. I'm hoping that I can call on the wisdom of the board to help me correctly size the system.
I have a semi detached house, double glazed with cavity wall insulation. The house has an east / west aspect with no windows to the north (solid wall) and nothing to the south (next door). The rooms are as follows:
SITTING ROOM
Patio doors to the east. 2m wide window and glazed wide front door to the west that catch the evening sun. The room measures 8.7m by 3.3m for a total of 28.7 square meters. Height is 2.4m for 68.9 cubic meters. The room is attached to the kitchen by a standard 30" door way, though there is no door installed, so air is free to flow. The kitchen measures 3.6m x 5m for total of 18 square meters / 43 cubic meters.
BEDROOM 1
Measures 3m x 3.5m. 10.5 square meters, 25 cubic meters. 2m wide west facing window that catches the evening sun. Heat reflected in afternoon off of porch roof into this window.
BEDROOM 2
Measures 2.4m x 2.4m. 5.76 square meters, 13.8 cubic meters. 2m wide west facing windows that catches evening sun. Gets more heat reflected into the window from porch roof than bedroom 1.
USAGE
The sitting room would be occupied during the day and evening.
Bedroom 2 would be occupied from about 6:30pm (small child).
Bedroom 1 is occupied from 10pm onwards (wife, myself)
MY CURRENT THOUGHTS
Based on my experience with a 5,800 BTU portable air conditioner (gift) in this house, it makes a modest impact in temperatures to bedroom 1, bringing it down from unbearable to something that is bearable, but still too warm for my liking on a summer's night. Little effect on sitting room, 1 perhaps 2'C after a long time running. I've also experienced a 12,000 wall mount split at my parents house in their kitchen.
Budget is not unlimited, but also I don't want to buy carp either.
I've been looking on line and have seen the LG Multi-F range, and they look to be reasonably priced.
LG Multi-F MU3M19 5.3kw 19,000btu Multi Split Outdoor Inverter
LG P12RK-NCB 3.5kw 12,000btu Indoor Unit in Sitting Room.
LG P09RK-NSB 2.6kw 9,000btu Indoor Unit in Bedroom 1
LG P07RK-NSB 2.05kw 7,000btu Indoor Unit in Sitting Room.Bedroom 2
Total indoor ratings exceed that of the outdoor, but they won't all be used to their maximum at the same time.
Please let me know what you think? I expect (hope) that I am in the right ball park, but would love to hear your opinion.
Many thanks.
