Inverter Air conditioners & the rising electricity tariffs in Ghana
My Nigerian friends often say Ghanaian folk have a signature look, very dark skin and red eyes. This they claim is as a result of the scorching sun in Ghana. Ghana is hot o…….
Average temperatures often range between 35-40 degree Celsius with high levels of humidity . Due to the nature of the weather in Ghana Air-conditioning is no longer a luxury.Most homes and offices who can afford , have invested in one form of cooling or the other while those who cant have settled for fans.But what happens when there is erratic power supply and load shedding AKA Dumsor in Ghana? I bet that is another topic for another day.

Recent electricity price hikes in Ghana have made Air Conditioners a pain point for most who are concerned about their electricity bills. Electricity bills increase significantly when an air conditioner is added to the list of appliances in a household. Although it is difficult to significantly reduce the “big” impact of an air conditioner on your electricity bills, it can be managed by choosing the right technology. Also by following the right installation/maintenance/operation procedure and also putting into consideration the insulation of room where the air conditioner is being operated.
The latest and the most efficient technology that is available on market today is the Inverter Technology for air conditioners. Inverter technology is designed in such a way as to save 30-50% of electricity (units consumed) compared to regular air conditioning systems.At Nocheski ,we live up to our promise of driving your business with technology and we recommend the use of energy efficient appliances such as inverter Air-conditioners from brands including LG,Daikin,Carrier Samsung , Gencool, Hisense just to name a few.
How do air conditioners work?
For most people, air conditioner just throws cool air at the temperature one sets it at. But does it really work that way? In principle, an air-conditioner during the cooling process, takes the indoor air, cools it by passing it through evaporator and releases it back in the room. It is quite opposite to how our good old air coolers used to work. Air coolers used to take outside air, cool it with water and throw it in. But air conditioners just work on internal air. Along with evaporator an air conditioner also has a compressor that compresses the gas (refrigerant) in the AC to cool it that in turn cools the incoming internal air from the room.
In a regular air conditioner:
The compressor is either off or on. When it is on, it works at full capacity and consumes the maximum electricity it is designed to consume. If the thermostat reaches the temperature level set in the AC, the compressor stops and the fan (in AC) continues to operate. Then the thermostat senses that the temperature has increased, the compressor starts again.

Air Conditioners with Inverter Technology
The inverter technology works like an accelerator in a car. When compressor needs more power, it gives it more power. When it needs less power, it gives less power. With this technology, the compressor is always on, but draws less power or more power depending on the temperature of the incoming air and the level set in the thermostat. The speed and power of the compressor is adjusted appropriately. Originally developed in Japan for use in air-conditioning systems, digital inverter technology is now applied globally in appliances such as refrigerators, washing machines and even microwave ovens.
Samsung has a new line-up of household appliances for the digital home that saves on cost and offers more features.
What is benefit of Inverter Technology?
Air conditioner is designed for a maximum peak load. So a 1.5hp AC is designed for a certain size of room and 1 hp for a different size. But not all rooms are same . A regular air conditioner of 1.5hp capacity will always run at peak power requirement when the compressor is running. An air conditioner with inverter technology will run continuously but will draw only that much power that is required to keep the temperature stable at desired levels. Hence Automatic adjustment of capacity based on the requirement of the room it is cooling and so requiring less electricity for efficient operation although air conditioner with Inverter Technology adjusts its capacity based on the room requirement, it is very important to install a right sized air conditioner in a room.
Its important that you evaluate the room and air conditioner capacity before you make a purchase.Moreover digital inverter technology appliances such at home further increases the business case for installing solar for home.This as a result of highly reduce electrical load.
