Summer in Australia can get quite hot with the average temperature recorded at approximately 40 degrees Celsius. To survive the heat, installing an efficient air conditioning system is absolutely necessary. Split air conditioning systems are a popular option because they are inexpensive, easy to install and also energy and cost efficient. Although split air conditioning systems are already known for being energy efficient, there are a couple of things you can do during the installation to further enhance this characteristic.
Prevent the Evaporator From Getting Plugged
Keep rainwater away from the outdoor compressor unit by installing a roof or cover overtop. The performance of the split air conditioning can be drastically reduced if water gets into the evaporator. When the temperature cools down at night, the water may freeze within the unit and prevent it from running smoothly and efficiently during the day.
Take a Look at the Layout of the Piping
Most homeowners are not aware of how important the pipes that connect the outdoor compressor to the inside unit are. There is a correlation between energy efficiency and noisiness of a split air conditioning unit. Using more piping will ensure no noise transfer, because the outdoor compressor will be much further away from the inside unit. This means you won't be able to hear it. The distance will greatly lower the energy efficiency of the unit because the cool air will get heated as it travels from the outdoor compressor to the indoor unit.
By using less pipes, the unit may become much noisier, but the overall energy efficiency will improve. You'll have to determine what works for you.
Properly Insulate the Ducts and Pipes
Although it may not seem necessary, insulating the ducts and pipes connected to the split air conditioning unit can help you save a lot of energy. The insulation will prevent heat exchange between the cool air produced by the air conditioning unit and the heat from the outdoors. Speak with your technician to determine the type of insulation that may be most suitable for your home. For example, consider whether open-cell polyurethane or closed-cell polyurethane can offer the best insulation properties.
Split air conditioning systems are already incredibly energy efficient. If you take the time to implement the tips above, you can be sure that your system will use the least amount of energy needed to regulate the temperature within your home even during the hottest summer days. In the long run, you'll end up saving the environment and a lot of money!
