An air conditioner is a device that produces cold while exhausting heat. Before investing, and possibly initiate work, it is important to assess the type of air conditioner you need.
Models of air conditioners
Portable air conditioners have an average power of 2 3 kW, ideal for temporarily cool a room from 20 to 30 m². Thanks to its wheels, this type of device can be moved from one room to another without concern sandstone needs. It is recommended for occasional use in areas where heat episodes do not last long and are not too strong.
These types of air conditioners are connected to a drain hose that is placed in an opening (a door ajar for example) or a vent crack reserved for that purpose. If you do not have to drill a hole 15 cm in diameter in a wall.
Split air conditioners have an external party (place outside the conditioned space) which contains a heat exchanger and fan. These two blocks are connected by a non-detachable flexible cooling and electrical connection.
The window air conditioners are in the form of a block where everything is included: indoor and outdoor heat exchangers, compressor and ventilation. They meet in the same element throughout the refrigeration circuit. These operate on the principle of air condensation, and must therefore reject the hot air out of the room. For this reason they must be embedded in a window or wall facing the outside. They are placed in a building opening, eg window (where the window name). If they contain less than 2 kg of fluid, no specific regulation is to be applied outside the electrical compliance, and laying in the rules of art. This type of air conditioner is to be used mainly for offices.
The split air conditioners are composed of at least two units (beyond talking about multisplit). One is located inside while the other is located in the room to be conditioned. Both are connected through pipes in which circulate refrigerant fixed or variable power. The outdoor unit’s role is to vent hot air, while the indoor unit distributes cold air into the room.
A split air conditioner has a mobile unit placed inside the house that can be moved by clockwork. The two components of the device are connected by flexible ducts.
A split air conditioner has fixed as its name suggests, two fixed units. Inside, the air conditioning vents are attached to the wall, freeing up floor space compared to a mobile split system. A multi split, which is necessarily fixed to a unit outside and several inside. So it can cool several rooms at the same time, an area of 80 m² maximum.
These are the most common models. Elements located inside the housing is fixed to the wall or ceiling. The intervention of a refrigeration is required to perform the installation of these devices, because the passage of cold pipes must be dragged into the walls. The installation does not last more than a day. Most of these devices are reversible, that is to say, they refresh in summer and warm in winter by a reverse operation. This system is very financially interesting because on one hand the device is useful all year, so quickly pays, and other winter mode is very economical. Indeed, one kilowatt of electricity absorbed provides three kilowatts of heat. However, this does not exclude the use of a booster heater if cold.
The selection criteria
Power: the split air conditioners are very efficient and allow to cool several rooms at the same time. Another advantage, most devices now have a split hot / cold function also allows you to heat a home. Window models are somewhat less effective than the latter. As for the mobile air conditioning, they represent a temporary solution but to avoid for the long term.
The difficulty of installation: mobile air conditioners require no installation, except perhaps the creation of a vent but it is not required for its operation.
To install a window air conditioner, little work is required. A novice handyman succeed to implement this type of device.
If you prefer to opt for a split air conditioner, it is better to use qualified personnel for installation.
An air conditioning repair greensboro technician would still be needed when your system stop working.
Noise: window air conditioners and mobile are relatively noisy (noise near a refrigerator), which can be annoying if you want to place in a room. Air conditioners split them are very quiet.
Aesthetics: the split air conditioners easily blend in contrast to window air conditioners or mobile that are not very aesthetic.
The price range
Knowing that the price of an air conditioner depends mainly on its power, placement and size of the room, we have low to high: window, mobile and finally split. These are the most expensive because in addition to the device itself, we must add the cost of installation and maintenance (once a year), which must be done by a professional.
