Commercial Air Conditioning in St Albans

What Is Central Air Conditioning System?

Central air conditioning system is a system which operates by cooling air at a central place and distributes the cooled air to and from rooms with the help of one or more fans and ductwork. What makes the whole idea of air conditioning feasible is the operations of the air conditioner compressor. When it cooling gas is compressed, it allows it to absorb heat from the house and blows it outside into the outside air and that’s exactly how the cool air is being generated.

Central air conditioning are of two main types which includes a split system as well as a packaged unit.

Generally, in the split system AC unit, both the condenser and compressor are included in the outdoor metal cabinet, whereas the indoor cabinet includes the evaporator. Typically, in several split system air conditioning units, the indoor cabinet will also include an air handler or a furnace. What’s more? The evaporator coil of the AC unit is fitted in the cabinet or the furnace or heat pump’s primary supply duct. This type of central air condition is usually the most economical AC unit to fit if you already have a furnace in your home.

However, in a packaged central air conditioning system, the components including condenser, compressor and evaporator are all included in one cabinet. Supply of air as well as the return ducts are connected through the home’s exterior wall or roof to the package central air conditioning system - mostly placed outdoors. This type of central air conditioners also features electric heating oil or a natural gas furnace. With this perfect blend of central heater with air conditioner, there’s simply no need to a separate furnace indoors.

Air conditioning filters can get dirty over time, especially through heavy use. This can have a major impact on how efficient a unit is, increasing how much energy it uses and reducing how effective it is.

This is why it’s a good idea to service your air conditioning system regularly. Part of this should involve checking, cleaning and replacing your filters, to help your units run as efficiently as possible.

Yes - in the Summer many UK homes could benefit from air conditioning, particularly in southern and eastern areas and is global temperatures increase with longer, hotter, dryer Summer months. Also, most modern air conditioning units function as heat pumps, meaning they can be used in winter as part of a heating system.

Several individuals think that the the way their air conditioning system works is simply by pumping hot air out of their homes or offices, blowing a cool air in return. This is absolutely wrong! The hot air is, in fact, cycled back in as cold air and this process continues until the thermostats gets dropped down to the required or set temperature. The air conditioning system manages this in a similar way to how the refrigerator manages to stay cold and of course, excluding the insulated box.

The short and simple answer to the question of what gas an air conditioning use is Freon. This is a non inflammable gas which is subjected to the evaporation process over and over again in most refrigerators to keep the temperature at a low level. This same process is repeated in air conditioning systems. Now let’s take a look at how the Freon gas is incorporated in AC systems.

The cold Freon gas is firstly compressed by a compressor in the air conditioner. The gas is then combined with a little quantity of oil in order to lubricate the compressor. When Freon gas is compressed, the pressure is increased which makes it incredibly hot. It then moves through a couple of coils which works to lowering the heat and turning it to liquid. This Freon liquid will then be transmitted via an expansion valve which causes it to cool down until evaporation takes place. The outcome of this is a low pressure cold Freon gas which is then transmitted via another set of coils allowing the gas to collect the heat and lower the air within the room.

The air conditioner now filters the air and clears out the dust, smoke, pollen and other kinds of air pollutants. The system also absorbs excess liquid from the air too which it uses to cool down the system and pump it through a hose.
