This type of air conditioner costs slightly more to procure and install compared to conventional window air conditioner units. Read this Hitachi split air conditioner review to learn more.
The condensing unit of a split system is usually located outdoors; normally, window type ACs have indoor condensing units. The compressor is what usually makes a lot of noise in most ACs, so having it outdoors helps to reduce the noise made by the system.
However, the evaporation panel is located inside the house. The interconnecting pipes are usually kept outside the house, so it’s only the sleek unit that is mounted on the wall. When building a home or remodeling, there is no need of designing windows that can accommodate the air conditioner, as is usually the case with window mounted units.
The split air conditioning system has two sections: the first one sucks air from a room and filters it while the other section (outdoor component) cools the air, removes moisture from it and releases it back into the room. There are some important factors that you need to be familiar with before you go shopping for a split air conditioning system.
The human body has a temperature of 37 degrees Celsius, or 99 degrees Fahrenheit. For a person to live comfortably in a room, the overall temperature must fall in the range of 70 to 79 degrees Fahrenheit with relative humidity ranging from 20 to 50 percent.
Before buying an AC, it is important to calculate the amount of heat that needs to be removed from a room and buy the appropriate device: a high capacity AC will make a room too humid while a low capacity AC will be overworked and it may not be able to perform optimally.
The ability of an air conditioning machine to cool or heat up a room is usually measured in kilowatts or watts. An enclosed space, like a room inside a house, with two occupants carries away 50 BTU (British Thermal Units) of heat every hour, per square foot of floor area. 3400 BTUs/hour is the equivalent of one kilowatt.
A room measuring 15 feet by 15 feet needs an air conditioner with a 11250 BTU rating (15 x 15 feet x 50 BTU per hour). With this rating, 1000 BTU/hour and 600 BTU/hour need to be added for every additional appliance or person respectively.
When looking for an air conditioning device, always go for machines that come with single phase connections; never buy 3-phase machines because they are usually more expensive to install and difficult to maintain. EER (Energy Efficiency Rating) is normally used to measure the energy efficiency of an air conditioner: this is the ratio of the unit’s cooling capacity to the power it consumes.
For effective cooling to take place, the air flow-rate in the house needs to be high, the insulation properly in place and the moisture removal rate of the system high. Be sure to buy a machine with a noise level that is less than 50 decibels.
Before you purchase an air conditioner, make sure it has a vane type compressor. This type of compressors usually have fewer moving parts compared to reciprocating compressors.
Split type air conditioners have auto modes which include auto restart, auto sleep mode, auto diagnosis, filter cleaning warning light and alarm, auto timers, and automatic changeover to dehumidification among others.
If you are looking for an elegant, sleek, aesthetically appealing split air conditioning system, be sure to choose reputable brands like LG, Hitachi, Daikin and Toshiba.
