Selection of cooling equipments needs good understanding about some technical features of the system that enhances its efficiency and helps to save cost. These equipments have become so indispensable for living that you have to think of using advanced technology that can save energy cost so that you enjoy the comforts of a cool home without straining your pockets. You must be well informed about the advanced features that are being incorporated in the latest centrally cooled systems so that you can say goodbye to the old system and welcome a new one. The new system could give you plenty of opportunities of energy saving without compromising on the cooling effects. Look for the following features in the system that can lower operating cost.
It is extremely important to understand the technological jargons that are used to define the efficiency of air conditioning systems. You must have heard about SEER, a term that is used to denote the amount of energy that is consumed by the system in order to achieve a desired level of cooling. The higher is the SEER or seasonal energy efficiency ratio the lower is the energy requirement for the system. Systems with higher SEER entails less operating cost and the accepted ratings of new equipments vary between SEER14 to SEER 26. Go for the highest rating of the system permissible by the budget that you have set.
Delinking the fan and compressor
The traditional concept in air conditioning considered synchronisation of the fan and compressor which run and stop together. There was no way to isolate the fan and the compressor. New systems are provided with a separate fan only switch that can be used to keep the fan running even if the compressor is switched off. This is particularly helpful when cooler days when only the fan can be used to maintain the desired temperature and this can save considerable energy.
Dual speed compressor
Compressors in the new air conditioning systems have two speeds. Higher speed means more cooling and lower speeds are or moderate and low cooling. These compressors operate on low speed for almost 80 percent of the time and meet the needs of low cooling on milder days that results in lowering energy cost.
Air handler with variable speed
The cooling requirements of homes are not the same throughout and keep changing frequently. Air handlers with variable speed option are capable of adjusting its speed according to the variable cooling needs. These units run at low speed for almost three-quarters of the time with extended cycles. This extends the life of the system besides making the air conditioning system more efficient with better air filtration and finer humidity control.
Delinking the fan and the air handlers
The compressor and air handlers are synchronised to operate together. But an automatic fan delay mechanism allows the fan to discharge the cool air trapped inside ducts even after the compressor has ceased working that saves the wastage of unused cool air that is left inside the ducts after the compressor has stopped.
