i have a 3 bedroom apartment...
should i go for 3 units of single split type or a multi split that supports 3 a/c
what are the pros n cons for both...
and in terms of power consumption...will it be more economical to go with the multi split?
thanks in advance for any comments
actually both got advantage & disadvantage
single split
Advantage: a) when any 1 break down, 2 units still can use.
b) save cost. if change brand new outdoor, it just cost 1 outdoor unit, not 3.
disadvantage: a) place too limited. because need put 3 units at the same time. so it may put outside window & may difficult to maintain & service
because high story of building. (unless got a specific place to put all air-cond)
b) may costly for minor maintenance.
multi split:
Advantage: a) save place. (only 1 unit for outdoor)
b) centralize. because 1 unit, not so ugly to look 3 units of outdoor unit.
disadvantage: a) too heavy. (difficult to change compressor if break down because of high story building.)
b) compressor break down, 3 unit no need to use.
c) too costly. if change brand new outdoor, it may cost 3 outdoor unit price. and the minor & major maintenance too.
*power consumption almost the same. because centralize outdoor unit just running 1 air-cond if turn on 1 air-cond. not turn on 1 air-cond, 3 running.
NO. if do like this, other 2 units which no turn on will cause freezing as result will huge water leaking once air-cond cut-off. unless it break down.
*cooling is depend on space & the BTU itself. the higher BTU, the cooler it is.
my recommendation is: go for single split. consider for future maintenance cost.
condominium, apartment will go for single split type.
if say about shopping mall. go for centralize which 1 unit around 100 HP.
