Decision: What types of Daikin air conditioners are there and which one is right for you?
Depending on your needs, different types of air conditioners pay off. In the following, we will discuss the three types: mobile air conditioner, split system and heat pump.
|Monobloc or mobile air conditioners||Inexpensive, very flexible, no installation necessary||Very inefficient, "power guzzlers"|
|Split air conditioners||Energy efficient, Individual units for each room||Costly, professional installation and maintenance required|
|Heat pumps||Cools in summer and heats in winter, Air-conditions the whole house, Very energy-efficient and environmentally friendly||High initial costs, Professional installation and maintenance required|
Mobile air conditioners or monobloc units
Mobile air conditioners are characterised by their flexible range of use. They do not require expert installation and are the cheapest variant among air conditioning systems.
Mobile air conditioners consist of a single "monobloc" in which everything is compactly installed and the warm exhaust air is discharged through a door or window gap. For this reason, they work very inefficiently - no monobloc unit with an exhaust hose comes close to the cooling capacity of a permanently installed split air conditioner. If you want to install several units, you will quickly generate a horrendous electricity bill with mobile units.
Split and multisplit air conditioners
Split air conditioners consist of two units: an indoor unit that takes in the air in the room and an outdoor unit that dissipates the heat outside. You can connect up to five indoor units to a multi outdoor unit, which can be of different types and different performance classes.
Because you can choose the optimal unit for each room individually, split systems are very energy-efficient.
Indoor units come in various forms. Common are built-in ceiling units or duct units, wall units or chest units that are placed on the floor.
If you use a heat pump as an air conditioner, you kill two birds with one stone: the system is used for heating in winter and cooling in summer. Moreover, heat pumps do not only air-condition individual rooms, but the entire house.
Heat pumps obtain up to 75% of the energy from the environment, the remaining part is covered by electrical energy. The common energy sources are air, ground and groundwater. Room cooling is made possible by simply reversing the heating process.
Buying criteria: You can compare and evaluate Daikin air conditioners based on these factors
Room size and required capacity
To find the best air conditioner for your room, it is important to estimate how much heat energy needs to be transported out of it (the so-called cooling load).
The larger the room, the more power the air conditioner needs to deliver. This power is expressed by the so-called BTU value ("British Thermal Unit"). 1000 BTU/h correspond to 293.71 watts.
A rule of thumb for calculating the cooling load is: room area in square metres times 60 (good insulation, little sun) to 100 (little insulation, much sun). For a well-insulated room of approx. 25 square metres, this results in a required output of approx. 2000 watts or 6800 BTU/h.
Here we consider the two parts of the air conditioner - indoor and outdoor unit - separately: outdoor units of high-quality Daikin air conditioners are on average no louder than 49dB, for indoor units we measure noise levels between 19dB and 40dB.
In a residential area, an air conditioner is legally allowed to be no louder than 50dB during the day and 35dB at night.
The outdoor unit should be as quiet as possible, especially for the sake of the environment and neighbours. In a residential area, an air conditioner may legally be no louder than 50dB during the day and 35dB at night. Information on this is provided by the Federal Immission Control Act and the TA-Lärm (Technical Instructions for Noise Protection); municipalities can issue additional ordinances.
A close look at the energy efficiency label is mandatory. Previously considered to be enormous energy guzzlers, air conditioners have come a long way in recent years in terms of efficiency and environmental friendliness. Nevertheless, this point should be one of the most important selection criteria when buying!
The energy efficiency of household appliances in Germany is indicated by the EU energy label for electrical appliances. The scale ranges from A (best class, lowest demand) to G (worst class). Through technical progress, more and more appliances received a good label, so that the classes A+, A++ and A+++ were additionally introduced.
Daikin air conditioners almost all have an energy class of A++ or A+++. Even this small difference is significant: with class A+++ units you save up to 30% more energy than with class A++.
Daikin split systems require an expert hand for installation; the cost of installation averages 200 to 300 euros.
However, the investment is well worth it, because an air-conditioning technician is familiar with the various problems involved in installing an air-conditioning system and knows which location is best for indoor & outdoor units. This alone can have a significant impact on the energy efficiency of the unit.
If you decide to do the installation yourself, buy your air conditioner pre-filled from the dealer. The required coolant is then already filled into the system at the factory and you don't have to fiddle around with it yourself.
Operation & maintenance
Only with regular, proper maintenance and cleaning can your air conditioner perform to its full potential and provide years of trouble-free service.
In addition to the purchase costs, there are annual operating costs for consumption. Split systems from Daikin have a high output - the operating costs are around 17 cents per hour, which means around 80 euros for a running time of 500 hours.
Maintenance, which should take place approximately every year and costs about 150 euros when carried out professionally, involves the following work:
- Refill or replace refrigerant
- Check for leaks and function
- Clean and disinfect
- Clean or change filters
- Replace worn parts
When buying a system, be aware that the larger and more complex it is, the more time-consuming and expensive its maintenance will be.
Interesting facts about Daikin air conditioners
How does an air conditioner actually work?
The Daikin split air conditioners we've looked at in this article consist of two parts: an indoor unit and an outdoor unit. Each unit contains metal coils through which refrigerant flows continuously. The indoor coil is called an evaporator, the outdoor coil a condenser.
Heat energy always flows from hot to cold.
We know from thermodynamics that heat energy always flows from warm to cold - never the other way round. The principle of an air conditioner is now as follows: The evaporator (spiral in the room) must be colder than the room temperature and the condenser hotter than the ambient air. Under these conditions, the refrigerant draws the heat from the room - the evaporator is colder than the air in the room - and releases it into the environment via the hot condenser. The following video illustrates the process:
How do I operate my Daikin air conditioner? Is there an app for remote control?
The operation of Daikin air conditioners is individual depending on the unit. Operating instructions are included with the appliance and can also be obtained online as a PDF. In general, however, the operation and symbols are very intuitive.
The operating instructions explain, among other things, switching on & off, night mode, setting the time and temperature, reset, connection with WLAN or Bluetooth, the timer function and control via remote control. In addition, the numerous symbols and signs are explained and also what the various error codes from u0 to u9 mean.
Daikin has also developed the "DAIKIN Online Controller" app, which allows you to control your system at any time and from anywhere. You can also make advanced settings via your smartphone.
What problems can occur with a Daikin air conditioner?
You can avoid many problems if your air conditioner is installed correctly. It is often cheaper in the long run to have the installation done by a professional than to try to do the work as a layman.
Below you will find common problems and advice on what to do in this case:
- Air conditioner does not work: Check whether there is a power failure or fuses have blown. Sometimes the air-conditioner does not start directly to prevent an overload. Refer to the operating instructions for information on flashing symbols.
- Air conditioner does not cool: Check whether the units and especially the filters of the indoor and outdoor units are clogged or dirty, as well as the temperature setting and the fan speed control. Direct sunlight and too many people can also reduce the cooling capacity. A refrigerant leak is also possible - a case for the specialist.
- Air conditioner goes on or off by itself: Perform a reset and change the batteries in the remote control. Check that all settings are correct. Too low a voltage can also cause the unit to switch off. If the problem persists, contact your dealer.
- Indoor unit dripping: Condensation is usually collected in a tray under the filter. If your air conditioner drips, it may not drain freely or there may be a problem with the condensate pump. Check the hoses and pump for dirt.
- Air conditioner makes noises: Certain noises are normal. For example, hissing or gurgling sounds occur when the refrigerant flows through the units. Try to identify the source of the noise and call a specialist in case of emergency.
