Multi split system is the only solution for me

EgunMogaji:
Central HVAC is less efficient.

Even here in California, the higher end homes are going to split system though some are linked.

YarAdua1:


mmmm...I don't know what part of California you live, but business and new homes use central air, split air units are generally found in cheap motels like motel 6, Days inn or very old homes/hostels/studios (pretty much small spaces, where it won't be logical to install central air). It costs a little more in incorporating an HVAC system in a home, but its way more cost effective and energy efficient downstream.

EgunMogaji:


It doesn't matter what part of California that I'm in. Simply state your own opinion.

Like I said higher end homes are moving to split system.

Split system costs way more than CAC so the integration is not yet main stream. Next time you go to Home Depot or Lowes, take a few minutes to talk to the Salesmen that are selling HVAC system.

I have CAC now but will be installing Split in my home in Nigeria.

I also stayed at The Ritz Carlton in Buckhead, Georgia a couple months ago (~ $500 per night) and guess what it didn't have CAC but split system.

GogobiriLalas:
Bros I live in LA and most businesses I see out here have CAC...the only businesses with split ACs are VERY small, sole ownership, one stall concerns and low rent apartments.

EgunMogaji:

EgunMogaji:




I specifically said higher end homes and you keep on harping about low rent apartments and one stall concerns

GogobiriLalas:
my point exactly, most high end homes have CACs...only low rent apartments go for split. You claim split is more efficient the data does not support your assertion.

domack99:
Why is it that our Engineers don't design a central Air conditioning systems in our high rise buildings. Is it that they are not cost effective or difficult to maintain?

EgunMogaji:


No you can't.

semitunde:


Bro. Those cooling systems are probably due for change. Though durable HVAC (Central AC) systems last for a much as 30 or more years; the maintenance and spare parts needed ( if the product is shipped from abroad) might become a problem.

@op the client determines (finally) if a building is going to have central AC or not.

HVAC systems have high initial financial outlay, but over time, compared to split ACs, their mmaintenance are more cost effective. Many clients however like to cut costs hence the choice for splits.

Hope you know the new senate building has been reverted to split AC system. Cost cutting measures.

Dollyak:
Central cooli system for that kind of building is load intensive. So how are you going to power it with ordinary generators you guys use in Nigeria?

Xtopher123:
It depends on what The client wants, it's more expensive tho install and more expensive to maintain..


Mind you it's most effective, especially in high rise/Mixed use building

For those saying individual room temperature cannot be achieved is a pure lie, each room can be zoned to operate on a different temperature
------------_----------
You don't design what a client cannot afford.. No thats a flop

Most Nigerian clients want it the normal way, they want the best but don't wanna spend the Cash..

Architecture/Engineering is a client that has money with an Engineer/Architect with vision

Mayflowa:


You can! Just that the supply energy needed to power it from the source won't be affected.

Central ac is most efficient when you both need heating and cooling. The initial cost is high and part replacement is costly.

You know, Western world spend so much building their houses. Our houses are simply constructed, yet there are shortage of housing here.

Reference:


Then why not design a central conditioning system that the client can afford. Is that not proper 'architecture/engineering'. But the fact is that our people allow Samsung and LG decide how our homes are designed, engineered and operated. Who says both needs can't be met.

msogunro:
Hahahahahahaha!!!! One of the outdoor units is covering a window. Hilarious. How is it even secured. They should invest in a multi split system.

With central a/c units, you cool/heat an entire house when you only need the room you're in conditioned.

Splits are more effecient because you can cool just the zone that you're in.

BE811APP:
Our architects are not innovative...No offense to dos in d proffession but its true

Why do u think Builders do a better Job on site and when I say Builders I mean those that didnt go to skol oo..

Central AC has nothing to do with the AC units. It has to do with installing the duct passages to deliver it across the entire building.
Any common window or split AC can be fitted to duct passages to deliver the cool air wherever needed.
Each room can be individually controlled by the duct vent which can be closed or opened.
Central AC is most efficient for cooling an entire building and the largest buildings. Its not as efficient for small buildings or a single small room.
The buildings in those pictures can actually be centrally cooled with less units and less power consumption if they used central AC.
But it would create complications if the electric bill is not shared or included in the rent or common dues. Also Nigeria's unstable power supply requires generator cost to be shared.
Central AC is better but more expensive to install and maintain. Also central air doesn't have the sound in the house because the blower is usually stored in utility areas undergorund or in an isolated area.
Nigerian houses dont have underground areas or isolated utility rooms for Heating and Cooling machines. So Central air would require a bulky and loud blower inside the house.
The AC units in the photo are nice but they have cluttered the building in a way that central AC would not.

EgunMogaji:


How many houses have you built for yourself that has central AC and have you ever worked on commercial HVAC in your life?

I know down there even omolanke driver is an engineer

EgunMogaji:

No you can't.

OrlandoOwoh:

The Senate Building being used doesn't have central ac either, just like other offices. But does the building of a new Senate Building not amount to waste of fund since there is an existing one with an extention?

martinsaba:


Shut up there, what do you know?
Don't assume what you don't know.
You can regulate any room in a central AC to suit what temperature you want

EgunMogaji:


No you can't.

oxyG:

Yes He can!.
However,maintaining a central A/C system is a major problem in an environment like Nigeria.

semitunde:


Don't mind the funny guy. Its people like him that one has to manage in projects. They always like to have an opinion even in issues beyond their comprehension. I give people like that the hardest jobs for them.to sink their hitherto wasted energies on. Keeps them.quiet for some time.

semitunde:


Whats this one saying?

I am a Civil Engr. Its what I used more than five years in OAU to study. What is it that you do? Say it confidently (or even rudely like you're used to). That you're the cleaner in a modest wood house construction coy does not confer authenticity to every lie you cook up.

I asked you not to misinform the public about your ignorance in the use of HVAC solutions and you decided to go rudely personal. Asking for my "friends" only prove you've been running you mouth for a long time. You found me in the right mood yesternight.

You know little to nothing of technical aspects of construction. Stick to your forte, just post pictures and keep it moving.
