Split System Air Conditioners
Split system air conditioners have outdoor and indoor units. The outdoor unit is installed outside the house or building and contains a condenser, compressor and expansion valve. The indoor unit houses the cooling coil, cooling fan and the evaporator. Unlike other, air conditioners, split systems do not require any slots to be made in the wall. Current models are smaller in size compared to window wall units, thus making them ideal wall-mountable air conditioners.Reverse Cycle vs Cool Only Air Conditioners
Reverse cycle split system units are helpful all year round as they provide heating during winters seasons and cooling during the summers. Cool only units on the other hand offer only cooling and work well in areas with tropical climates. The climate of your area is a key factor to consider when trying to determine which unit to go for. Keep in mind that each split system air conditioner is individually controlled. Multi-head split system air conditioners have a single condenser connected to multiple heads and are ideal for use in rooms that have limited outdoor areas.Inverters vs. Non-inverters
Inverter air conditioners are able to to adjust the fan's speed with regards to the cooling demand while non-inverter systems come without this feature. Depending on the split system design, some inverter units are set to start at high speeds so as to quickly bring down the temperature of a hot room. The speed automatically reduces after the desired temperature is achieved to maintain the room at that temperature. The ability to reduce or increase the cooling capacity avoids the need for cycling (stopping and starting).Capacity
Split air conditioners come in different capacities. The floor area and height of your room determines whether you should go for a high or low capacity air conditioner. The capacity of an air conditioner determines its effectiveness and energy efficiency with regards to the size of the room. Generally, larger rooms need higher capacity air conditioners and vice versa.Energy Efficiency
A ten-star scale is used to rate the energy efficiency of split air conditioners. Units that have both cooling and heating functions have different ratings for each function. The ability to regulate temperature without starting and stopping makes inverter units more energy efficient.
