Worried about your electricity bills?

Have you ever wondered how much your Air Conditioner costs you to run? Do you worry about if it is driving up your electricity bills? RPM explains Inverter Technology and Reverse Cycle Air Conditioning and how it can save you money!

Saving on electricity bills starts with Inverter technology. An inverter in an Air Conditioner is used to control the speed of the compressor motor to drive variable refrigerant flow in an Air Conditioning system to regulate the conditioned-space temperature. By contrast, traditional Air Conditioners regulate temperature by using a compressor that is periodically either working at maximum capacity or switched off entirely. Inverter-equipped air conditioners have a variable-frequency drive that incorporates an adjustable electrical inverter to control the speed of the motor and thus the compressor and cooling output.

The variable-frequency drive uses a rectifier to convert the incoming alternating current (AC) to direct current (DC) and then uses pulse-width modulation in an electrical inverter to produce AC of a desired frequency. The variable frequency AC drives a brushless motor or an induction motor. As the speed of an induction motor is proportional to the frequency of the AC, the compressor can now run at different speeds. A microcontroller can then sample the current ambient air temperature and adjust the speed of the compressor appropriately. The additional electronics and system hardware may add cost to the equipment installation but can result in substantial savings in operating costs in the long term. Inverter-Chart

What is a reverse cycle air conditioner and how does it work?

The principle of reverse cycle Air Conditioning is about a heat pump that works by transferring heat energy from one place to another to keep your room at a comfortable temperature.

Split system room Air Conditioners are made up of two separate units, one located inside the room and the other outside. They are joined by two insulated copper pipes which circulate a refrigerant. In cooling mode, warm air from the room is drawn into the indoor unit where heat is absorbed and removed. The air is recirculated back into the room providing cool, comfortable living even on the hottest summer day.

By a simple press of a button your heat pump runs in reverse to keep your room cosy and warm on winter days.

Reverse cycle room Air Conditioners uses Inverter technology, which allows for high power operation to cool or heat a room quickly to the desired set temperature. After reaching the set temperature, the operation is maintained at a low constant power.

Majority of Air Conditioners sold today have the inverter technology. At RPM Enterprises, we are here to help save you money on your future electricity bills! Speak to us today and we can discuss which brands can save you money in the long run!
