Central Air Conditioning

Central Air ConditionerCentral air conditioning is the ultimate form of air conditioning as it can use a central cooling plant to control the temperature throughout an entire building. With a properly sized installation, central air conditioning can cool everything from a small holiday home with three rooms to huge buildings such as hospitals, office blocks, and airports.

A central air conditioning solution is the most expensive if you happen to be considering an installation in your home. However, also the solution gives the best results. It is versatile and gives the options of cooling the whole building or just parts of it.

 Ducts and central air conditioning

The main unit of a central air conditioning unit produces plenty of cool air through the standard methods of condensing and evaporation, but it is necessary to move this cool air away from the air conditioning unit to be directed to the room where it is required. Fans that are used for a single room air conditioning unit will not work for a central system so the cool air needs to be transported through a network of ducts.

Ducts are like a network of “pipes” that are connected to the air conditioner and extend all through the building to vent openings into different areas. It would be ideal to install the ducting for a central air conditioning system at initial build, but the ductwork can be added later. It usually involves some internal remodelling of walls and structures. A good duct system is critical to the function of a central air conditioner.

Features Of Central Air Conditioner Duct Systems

Warm air needs to be drawn in to the central unit and cool air expelled from it. Therefore, two duct systems are required – supply ducts which route the cool air where needed and return ducts which intake warm air for cooling. Your air conditioning engineer to create the optimum air movement and pressure flow uses complex calculations in planning. This is why it is so important to use a qualified, accredited air conditioning company.

The major advantage that a central air conditioner offers is that duct branches can be included so that fresh air from outside is used rather than recirculated air which has clear health advantages and keeps air fresher and cleaner rather than reusing the same stale air over and over again.

Central air conditioners offer the ultimate comfort. Although more complex and expensive, they offer a total solution giving you total control over the atmosphere and temperature control in you premises. A definite plus point when it comes to marketing a home these days, air conditioning is becoming more sought after by house buyers who even in the UK have realised the benefits of this type of system. Although the cooling properties of the central air conditioning system have been spoken about here, the same system can also provide heating so you have a year round comfort any time of the day or night.

How we got here

Air conditioning is known to have been applied in Ancient Rome: aqueduct water was passed through walls of houses to cool them. In medieval Persia similar techniques involving the use of cisterns and wind towers were used in the hot season to cool buildings.

Modern air conditioning emerged after advances in 19th Century chemistry, and it was Willis Haviland Carrier who invented and first used a large-scale electrical air conditioning system in 1902.

Air Conditioner Definition

An appliance, unit, system, or machine designed to stabilise the temperature and humidity of air within an area (used for both heating as well as cooling). A refrigeration cycle is the most common method of achieving this although sometimes evaporative coolers are used for comfort cooling inside buildings and vehicles.

Real Life Escapes Through Air Conditioning Ducts!

air duct escapeWe have all lost count of the endless movies and television serials where the protagonist is either using air conditioning ducts to crawl through to break into a museum or bank to pull off a daring robbery or alternatively prisoners breaking out of prison in daring jail escapes. It makes for riveting, tense and thrilling viewing, but does this really happen in real life? We have searched the web to bring you some real life tales of air conditioning ducts used for dubious purposes!

By Joseph Alexiou (October 25 2011) Prisoner stages elaborate escape through air conditioning system and over wire fences… only to be caught hours later Mail Online retrieved March 21, 2012 from http://www.dailymail.co.uk/news/article-2053406
Excerpt
“A prison inmate who staged an elaborate escape, was left dismayed after he was captured just hours later.

Leviticus Uriah Taylor, 25, who was being held at the maximum security block at Indian River County Jail in south-east Florida, launched his freedom bid with cellmate Rondell H Reed, 52.

The daring escape on Sunday night saw the two men, both considered highly dangerous, crawl through air conditioning ducts and scale 12-foot fences covered in barbed wire.

But while Reed’s efforts were successful, Taylor was caught just hours later and returned to custody.

Reed, who is facing a second-degree murder charge, and Taylor, who was convicted of first degree murder last month, came up with the plan during the five days they were held together as cellmates.

Their escape is believed to have seen them break into a prison maintenance area, where their overalls were later found.

They would have then had to pass two locked doors before climbing through air conditioning ducts.

The final part of their escape saw them scale a 12-foot high fence topped with barbed wire that surrounds the jail. Investigators believe blankets found nearby were used to protect against the razor wire.”

By Unknown (October 8 2011) Police arrest 4 would-be robbers in Miami Beach retrieved March 21, 2012 from http://www.wsvn.com/news/articles/local/21005067275366
Excerpt
“Miami Beach Police have arrested four armed men accused of attempting to rob a South Florida gas station, early Wednesday morning.

The incident began just after midnight at the Shell Gas Station on 71st Street and Abbott Avenue. Someone alerted police after spotting four armed men with guns putting on ski masks outside of the gas station.

Authorities said the fourth subject used a ladder to climb on to a roof of the restaurant and hid in the A/C duct, where he became stuck. Miami Beach Police Detective Juan Sanchez said, “While on top of that restaurant, he was able to break the air conditioning duct vent system and get into this crawl space.”

The fourth subject was eventually pulled out of the air duct by SWAT team members. They needed to tear open ceiling panels and used a camera to find him. They then broke out ceiling tiles to pull him out by his feet.

No one was injured in this incident.”
