Photovoltaics for air conditioning
Photovoltaics for air conditioners TWO UNIT AIR CONDITIONERS
At a glance:
• Separate air conditioning systems are much more efficient than single-unit units.
• Since the compressor is installed outside, it is hardly audible.
• The installation needs some work.
How does a split air conditioner for photovoltaics work?

The term "split" comes from the fact that in this type of air conditioning the compressor and the cooling unit are separated spatially. The refrigerant evaporates in the cooling compartment, which is located inside the apartment, and absorbs heat from the room air. The heated coolant is then compressed outside the building, which liquefies it again and releases heat into the outside air. It then flows back into the device and the cycle starts again. The two parts are connected via 2 pipes or tubes, for which you need a wall opening.
Photovoltaics for air conditioning What are the pros and cons?
The spatial separation of the cooling section and the compressor prevents the flow of hot air, as is the case, for example, with mobile air conditioners. This makes these devices work more efficiently.
Compared to monoblock air conditioners, there is also the advantage that the system operates much quieter. The reason: The compressor is installed outside the building. This also has the advantage that it does not take up space inside. This is economical, especially for smaller apartments.
The disadvantage of this principle is the relatively complicated installation, as the external and internal parts have to be attached separately. In addition, it is necessary to drill the outer wall for the pipes. Acquisition and installation costs are therefore higher than for mobile devices. In addition, the supply air - in this case the outside air from the front - may be colder than the supply air from a central air conditioning position due to rain or wind. As a result, the air must be additionally heated, which can have a negative effect on energy efficiency.
Photovoltaics for air conditioning What useful add-ons are there?
With some systems, heating is also possible. To do this, the cooling section and the compressor simply change their function. For example, in the transition phase, when the central heating is no longer working or is still not working, air conditioning heating may be useful. However, not all devices are equipped with this feature. For example, air conditioning systems are manufactured by Mitsubishi Electric. The company also has very economical devices with A ++ or A +++ performance series in its series.
In addition, many split units are also air conditioners. These have the advantage that they can regulate their performance and thus cool more energy efficiently. The manufacturer Daikin, which is popular, produces such systems, among others. Models without inverter operate at full power until the desired temperature is reached and then switched off. This consumes more power and is also detrimental to the life of the device.
Photovoltaics for air conditioning Conclusion
Because the compressor is located outside, this type of air conditioning system has the advantage that it does not take up much space inside and causes much less noise there. The subsequent flow of hot air is not possible due to the separation of the system into 2 parts. However, there is initially more installation effort. If you want to air condition several rooms in your apartment, buying a multi-separate air conditioning system with several indoor units can be worth it.
