Central Air Conditioning Systems for Cooling

The mostly used central air systems are split air conditioning systems. It contains an outdoor cabinet with compressor, condenser coil and an indoor evaporator coil. It has installed in conjunction with furnace or air handler. The compressor pumps a chemical which is called refrigerant through the system.

Central air systems flow into cool air via a system of supply and go back to ducts. Supply ducts and registers (i.e. openings in the walls, flooring, or ceilings protected by grills) carry cooled air from the air conditioner to the house. This cooled air turns into hotter because it circulates via the home; then it flows back to the central air conditioner thru return ducts and registers. Air conditioners help to dehumidify the incoming air, however in extremely humid climates or in cases in which the air conditioner is oversized, it may no longer achieve a low humidity. Strolling a dehumidifier for your air conditioned domestic will growth your electricity use, both for the dehumidifier itself and due to the fact the air conditioner will require extra energy to cool your house.

A preferable alternative is a dehumidifying warmness pipe, which can be added as a retrofit to most existing systems.  Combustion gases are generated via the use of the burners on your furnace and passed via a heat exchanger. Air from your central home blows at some stage in the heat exchanger to be heated. It is then blown through a system of ducts to distribute around your home. Sooner or later of heat seasons your heating device works along with your central air conditioners. Air is cooled because it’s blown over your air con unit’s cooling coil, frequently attached to the air circulating fan of the furnace, after which sent thru the same air ducts within the direction of your private home.

Once warm air inside your house blows across the indoor evaporator coil, its heat energy transfers to the refrigerant in the coil. That transfer, in turn, “cools” the air. The refrigerant is pumped lower back to the compressor wherein the cycle starts again. The heat absorbed through the refrigerant is moved outside your own home even as cooled air is blown interior. Moisture that contributes to humidity is also condensed out of the air.

Types of Central Air Conditioners

A central air conditioners could be either a packaged unit or split system unit.

If we consider packaged central air conditioners then the compressor, condenser and evaporator, all are located in one cabinet which is usually situated on your roof or on any concrete slab just next to the foundation of house. These types of air conditioners are used in small commercial buildings. Air supply and return ducts come from indoors through the house’s outside wall or roof to connect with the packaged air conditioner, which is usually placed outside. Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and valuable heater gets rid of the want for a separate furnace indoors.

Now if we go to Split air conditioners, in a split air conditioner unit, an out of doors metallic cabinet includes the condenser and compressor, and an indoor cupboard includes the evaporator. In lots of split air conditioner systems, this indoor cabinet additionally incorporates a furnace or the indoor part of a heat pump. The air conditioner's evaporator coil is established inside the cabinet or fundamental deliver duct of this furnace or heat pump. If your house already has a furnace but no air conditioner, a split-system is the maximum low-priced valuable air conditioner to put in.

As compare to room air conditioners central air conditioners are more efficient. Buy energy efficient air conditioners if you want to save energy and money. It reduces energy use of your central air conditioning system.

Few common Problems

The air conditioning system will not operate at all

The air conditioning system is working but no cool air comes out

The AC is not blowing air

Leakage of water from the AC

Air Conditioner Makes Noise

The compressor is noisy during start up

The air conditioner fuse keeps blowing or the circuit breaker trips

Few things to keep in mind while installing Central Air Conditioners

•You air conditioners should be environment friendly which means it should be installed in such a way that it reduces impact on the environment and is highly energy efficient.

•The air conditioners system should be installed in such a manner that it is successfully control humidity and gives out a comfortable and cool indoor air.

•However, proper installation should take care of all the fact that it throws out stale air and other pollutants from the room and brings pure and fresh air.
