The amount of cooling or heating required by an air conditioner will vary depending on the outdoor temperature and the amount of heat in the room.
Conventional air conditioners operate their compressors at a fixed speed and therefore deliver a fixed amount of power. As a result the compressor must continually stop and start to maintain the desired room temperature. Inverter driven compressors, on the other hand, vary the speed of the compressors, delivering precise cooling or heating power as required.
When the compressor operates at a high speed, the amount of refrigerant flow through the system increases, increasing the cooling or heating capacity. Conversely, when the compressor operates at a low speed (during moderate outside temperatures for example), the amount of refrigerant flowing through the system decreases, thus decreasing the capacity.
When the inverter air conditioner is switched on, the compressor operates at a high speed in order to cool or heat the room quickly. As the room temperature approaches the set temperature, the compressor slows down, maintaining a constant temperature and saving energy. If there is a sudden fluctuation in the room temperature, the air conditioner senses this and instantly adjusts itself to bring the room temperature back to the set temperature.
Not only do Daikin inverter air conditioners use less electricity to operate, they are also highly energy efficient.
How does it work?
The refrigerant is the special liquid which flows through the indoor unit(s) to absorb the excess heat indoors. It then evaporates and is carried through narrow copper tubes to the outdoor unit as a gas, where the heat is released into the atmosphere. Thus, the gas becomes a liquid again and flows back to the indoor unit(s), where air is fanned over it and out into the room. This cycle is repeated until the preset temperature is reached.
Heat pump air conditioning units additionally allow the cycle described above to be reversed. A heat pump extracts "free" heat from the outdoor air and transfers the heat indoors. This principle even continues to function on very cold days with temperatures down to -5 °C, -10 °C or -15°C, depending on the type of air conditioning system used. Therefore, heat pump units eliminate the need for a heating system and allow you to cool and heat with the same unit, with savings in costs and energy throughout the year.
