There is no denying that an air conditioner is a demanding energy consumer. Obviously then, if you want an air conditioner, you have to consider your choice carefully and take a look at its energy consumption. 


An energy efficiency label will be shown on the air-con and it will provide important information on the energy efficiency rating as well as its projected yearly energy consumption. We take a look at ways you can reduce the power consumption of your air-con.


Aircon maintenance


Regular maintenance is important for your PTAC unit and cleaning the parts and replacing worn parts will make your system run more efficiently. This is also if you want to prevent costly repairs further down the line. 


In fact, not only do they need to be cleaned regularly, but disinfected as well, especially with the coronavirus. Preventative maintenance with these air-cons will allow owners of the air-cons to see problems in advance, repair them and save energy. 


Studies reveal that your unit will maintain up to 95% of its original efficiency. Filters, particularly, can become blocked with dust, slowing your system down and causing it to use more power. 


Retrofit your current A/C unit


It is possible to upgrade parts on your old unit if you want it to be more efficient. A refurbished PTAC units supplier that supplies quality parts can be useful for when you can’t afford to upgrade to a new, costlier system. 


You can reduce aircon power consumption by replacing the compressor, for instance. Getting an air conditioner repaired, however, can be a costly business, having the thing dismantled, cleaned, repaired and transported. Certainly, if regular breakdowns are becoming too frequent, you may want to explore a new air-con unit. 


Corrosion protection


The weather can actually play havoc with your PTAC air conditioner. Weather-related corrosion can negatively impact the performance of the cooling system. Some material-coatings can help in decreasing corrosion from salt and moisture so that energy performance can be enhanced. 


Your aircon technician will also tell you that energy performance can further be enhanced by substituting stainless steel for copper in the design of outdoor coils. 


Think out of the box


If you’re in the market to replace your air conditioner, shop around a bit before you automatically settle on the same system that you’ve always used. Yes, a new one will always be more energy-efficient, but you can actually reduce energy consumption even further with something like VRF – Variable Refrigerant Flow. This is a system that adjusts to run at only the capacity needed for the current conditions. 


As it is, it controls different areas in a building. This sophisticated VRF technology can provide cooling and heating, as well as both simultaneously in different areas. They’re quiet and energy-efficient with the variable-speed compressor running only at the capacity needed for the current conditions. 


Look out for the latest technology


The kWh figure for the annual energy consumption is to help buyers calculate how much it will cost to run the air conditioner in the year. You just have to remember that people use air-cons differently and the energy usage will vary.


Enhancements to these packaged terminal air conditioners not only ensures hotel guests enjoy supreme comfort, but energy usage is reduced. Hoteliers should look for the best technology – drain kits and two-fan systems as examples. It makes sense that if no-one is using a room, the aircon should be switched off to avoid wasting energy. Only turn it on again when the room is occupied.
