Depending on your location, there are various types and its size varies.
To those who know, its commonly called 3/8" which is the size but its referred to as Coarse Sand. It's an aggregate material and does the same work as granite. It can be used for german flooring and lintel casting.
Not to be used for casting of decking slabs.

You can use it mixed with sharp sand or just it alone with cement. Ensure you use a good mix ratio.

Quick question :

Is there any reason why New homeowners are not embracing installing central air condition in their houses?

Lots of times, we see a fine duplex with air condition boxes littered all over the walls.

Is there any structural/architectural argument as why homeowners shouldn't embrace using central air in their homes?

In the Nigerian context, the installation cost would be prohibitive for domestic use and recurrent maintenance cost and expertise would be afurther problem.

The main reason central air-conditioning system is not prevalent in Nigeria is the air duct system (see photos) and the way we build in Nigeria. In the USA, ceiling decking system is all wood so the air duct, water piping and electrical wiring can be passed through the void and space of the wood frames.

But in Nigeria we deck with concrete, so for a duplex how would you install the air duct system if not to think out some other ways to pass the duct through the concrete which could be very costly or unsightly.

Again the poor state of power supply is another problem. You will need a heavy duty generating set to power a central A/C which most homes seldom use. Most homes for cost cutting reasons use 1KVA GenSets which can power a single unit A/C.

Good explanation, but these days we have multi split unit system that can cater for a bedroom flat i.e one outdoor to 3 to for indoor rather than having outdoor for each indoor. Most of the commercial buildings and some residential building inside Banana island are using VRF system. They have low power consumption that's the advantage.

See how this house is flooded with outdoor

Please, like how much is it going to cost to fence an half plot of land, especially if someone is going to mould the blocks manually.

By my estimation a 3 bedroom flat would require 1hp per room plus dining and a 2 hp for the living room. This brings the total to 6hp in comparison to the same powered central cooling.

Before i continue, it is a fact that a window AC unit is more efficient to a split AC system. Reasons being that power waste by longer piping and distance between evaporator and compressor. These leads to losses in cooling capacity and pumping capacity. Longer piping also leads to increased costs.

The same effect is multiplied in the central AC where the refrigerant pipes are far longer leading to greater loss of efficiency. This does not even account for more insulation, more electrical connections/control gadgets and more installation cost.

In other words, a 6hp window unit required by a 3 bedroom may be equivalent to 8hp slit ac and equivalent to 10hp central ac. Secondly, all costs are increased while more cooling capacity is required leading to more cost.

The VRF is a technology which means more cost too. In the end, when you talk about cost, central ac is quite expensive.

But to me that is just saying we should continue with the same status co, there are various VRAF system that dosen't need the heavy ones with 20HP. i Have a multisplit system that i will be installing soon with very low current usage and absolutely no surge because it is an inverter system.
Hope to shopcase that when installed. it is so efficient that when only one unit is used the split outside system reacts only to that and dosen't take the whole current as to if the three are used at once

jabolo:


I am researching the multisplit options as I also abhor the clutter. Trouble is, the original building design ought to have considered it in the first place and hidden ducts can be provided for. It is difficult to retrofit into a completed building.

Having said that, we'll get there someday, so I would appreciate recommendations on the best vendors for multisplits in Nigeria.

Thanks in advance.

That is not true with the new gas system which is more enviroment friendly and it density is also very light (R32) you hardly need a big HP and distance dosen't play a big role till 60metres and height till about 10metres

kopell:
Power waste by longer piping and distance between evaporators and compressor. I disagree with this comment in regards to AC capacity, technology as taking care of that. Chillers are mostly used in heavy demand cooling in most commercial buildings, the can push as much far distance as needed.
