In recent years, DC inverter air conditioner is becoming more popular compared to the conventional air conditioner due to its many advantages. As the compressor takes the most power in any air conditioning system, the change in the compressor technology has enabled better and more efficient air conditioner or heatpump to be deployed.
Air Conditioner is definitely a pain point for most Nepali to their valid concerns in regards to their electricity bills. The fact is that the moment an air conditioner gets added to the list of electronic appliances used in a household, electricity bills increase significantly. Though it is quite difficult to reduce the “massive” impact of an air conditioner on your electricity bills, a considerable portion of it can be managed by choosing the right technology, optimized usage, doing the right installation, maintenance, operation and insulation.
DC Inverter Air Conditioners are newer in the market and they usually come with a different rating. While non-inverter air conditioner have energy efficient rating, DC Inverter air conditioners are marked with Inverter rating. Let’s take a look at the basic differences between DC Inverter Air Conditioner and Non-inverter Air Conditioner;
Non-Inverter type Air Conditioners
Non-inverter or fixed speed or Constant type air conditioners operate on a fixed amount of power at a fixed speed. This means the compressor has to stop and start again to maintain the desired room temperature. In this type of arrangement the compressor is either off or on. When it is on, it works at full capacity consuming full electricity. When the thermostat reaches the required temperature setting, the compressor stops and the fan continues to function. When the thermostat senses that the temperature in the room has fluctuated, the compressor starts again.
DC Inverter type Air Conditioners
This technology was developed in Japan and is now being used globally for air conditioners and refrigerators alike. In DC inverter air conditioning systems, the speed of the compressor varies to ensure energy efficient operations and precise cooling or heating as required. The DC inverter technology acts like an accelerator in a car. When the compressor requires more power, it gives it more power. When it needs less power, it provides less power. In this kind of setting, the compressor is always turned on, but draws less power or more depending on the temperature of the incoming air and the setting adjusted in the thermostat. The speed and power of the compressor is also adjusted accordingly.
Major difference between DC Inverter & Non-Inverter type Air Conditioners
DC Inverter air conditioner nowadays offer more functions than Non-inverter air conditioner. Both Air Conditioners differ in terms of compressor motor type running in the system. The compressor is responsible for compressing the refrigerant into liquid after which it shuts off and allows it to expand. As this process takes place, the refrigerant begins to cool thus producing the desired effect of cooling. DC Inverter air conditioner units are designed in such a way that they save up to 40-75% of electricity units consumed as compared to a regular air conditioner.
How DC Inverter Air Conditioner actually works
The magnitude of cooling or heating required by an air conditioning unit varies depending upon the outdoor temperature and the amount of heat in the room. When the cooling or heating effect needs to be amplified, the compressor will operate at a higher speed and will upsurge the amount of refrigerant flow.
On the contrary, during moderate outside temperatures for example, when the cooling and heating capacity needs to be reduced, the compressor will run at a low speed and will decrease the amount of refrigerant flow.
When the inverter air conditioner is switched on, the compressor operates at a high speed in order to cool or heat the area rapidly. As room temperature approaches the desired temperature, the compressor slows down, maintaining a constant temperature. Any spontaneous fluctuation in the room temperature will be detected and promptly adjusted to bring the room temperature back to the set temperature.
In short, it automatically adjusts its capacity based on the requirements of the room, thus drawing much less power and consuming lesser units of electricity. Although DC Inverter technology based air conditioners adjust their capacity based on the room requirement, it is very important to understand that installing a right sized air conditioner will provide the desired cooling/ heating results. It is recommended that you evaluate the room and air conditioning capacity before you make a purchase.
