Whenever you hear Mitsubishi you may recollect a visual of Mitsubishi car. Well, automobile is just one of the several businesses that are run by the Mitsubishi group—which happens to be the largest trading company of Japan. They have several business operations ranging from finance to banking, from machinery to energy, from food to chemicals, employing more than 60,000 people across the globe. This might surprise many, but Mitsubishi has been operating in India for more than 50 years. Even more surprising is the fact that Mitsubishi offers air conditioners under two separate companies—Mitsubishi Electric and Mitsubishi Heavy. Mitsubishi Electric has been spun off from the Mitsubishi Heavy almost 100 years back and since then both the companies make their own unique products rivaling against each other!
Mitsubishi Electric offers a wide range of air conditioners from residential wall mounted ones to commercial duct ACs. Let us look in detail of latest technologies that new Mitsubishi Electric ACs come with, and then discuss the pros and cons of Mitsubishi air-conditioners.
Latest Mitsubishi AC Technologies
Wide and Long 7-way Airflow
Eco-friendly MS-GK series of ACs from Mitsubishi Electric allows users to adjust the horizontal airflow in 7 directions and vertical airflow in 6 directions which translates into 42 different ways of cooling! So now with that sort of precise control, you can bring comfort at any corner of the room. The motor used inside the new models is of good quality which pushes air out further inside the room up to 12 meters with ease for comfortable cooling.
Robust and Effective Hardware
Being a Japanese brand quality is of supreme importance for Mitsubishi manufacturers. Newer models come with tropical inverter technology.
You make ask what inverter technology in the first place is. Well, to be really simple, inverter technology is analogous to the car accelerator. When the 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 are adjusted appropriately.
Mitsubishi Electric ACs come with a tropical inverter which has highly specialized inverter power module which is like a brain of the air conditioner able to adjust the frequency as per the ambient atmospheric conditions for comfortable cooling and efficiently managing power consumption. ACs coming with tropical inverter can work in temperature as high as 52oC.
Models from MSY-GR(T) series comes with propeller fan which converts rotational motion into thrust. Propeller fans from the aforementioned series deliver more air volume with minimum noise.
For its new offering, Mitsubishi Electric has developed a specialized motor, called the Poki-Poki motor which is manufactured using a lap joint technique. This Poki Poki motor generates high-magnetic force, leading to high-efficiency operation and reliability. Similarly, powerful neodymium magnets are used in the DC rotor compressor which imparts strong magnetic and reluctance torques for efficient air conditioning.
New Mitsubishi Electric models come with pulse amplitude modulation (PAM) technology that controls the current signal so that it resembles (or sync) with the voltage signal. Technically by doing so the loss of energy is minimized. Mitsubishi believes this way 98% of the input power supply is being effectively used for cooling the room
Mitsubishi Electric has developed twin linear expansion valves (LEVs) circuit with a power receiver that facilitates optimal compressor performance. Linear expansion valves act as a magnetic field and either spins clockwise or counter-clockwise to open or close the refrigerant flow. Twin LEV arrangement helps in optimal refrigerant flow for uniform cooling.
Auto Restart Function
Power cuts aren’t uncommon in India, especially in small town and villages. With power coming and going not only endangers longevity of electrical appliances but also resets their running settings i.e., supposed you were running your AC on fan-only mode (compressor turned off) but after power cut, AC’s settings are set back to default and compressor may start working again and even temperature setting would be altered. But thankfully Mitsubishi Electric ACs come with Auto Restart function that keeps a log of running settings before the power cut and after the power cut, it will restore the previous settings back. So now you can sleep peacefully all night without worrying about AC settings getting changed after a power cut.
Useful LCD Remote
One of the things we liked about Mitsubishi Electric ACs from the MS-GK series is they come with a smartly designed LCD remote control. Large, easy-to-find buttons sit on the remote for each access to frequently used function like increasing or decreasing of temperature and on/off button. Then there is a gamut of button for various setting hidden inside the sliding cover which can be used by sliding down the cover. The neat and clear LCD display lets you conveniently check the temperature and other operating conditions on the remote itself. And in case of some issues inside the AC remote will display error codes which would help the technician to quickly identify the issue for faster resolution.
Aerodynamic Technology with Crossflow Fan for Silent Cooling
Modern Mitsubishi ACs come with unique crossflow fan construction that allows air to flow smoothly through each rotating blade with bare minimum noise generation. With just 18 dB noise generation for indoor unit, Mitsubishi Electric is one of the quietest air conditioner brands around.
Nano platinum and Micro particle filter
Non-inverter models from Mitsubishi Electric comes with Nano Platinum filter which comes with a nanometer-sized platinum with a large capturing area to catch and kill even the minutest of bacteria and filter out smallest dust particles. It also deodorizes circulating air to ensure good circulating air quality. Additionally, they are also equipped with the Electrostatic filter which is charged with static electricity to capture allergens such as molds. After trapping this filter decomposes them using enzymes retained in the filter.
Inverter models, on the other hand, come with Micro Particle Catching filter that can effectively eliminate PM 2.5 particles and catch smaller dust particles.
Being a Japanese brand Mitsubishi Electric develop products that are robust and reliable. The special coating is applied on heat exchangers to prevent them from getting corroded. The printed circuit board (PCB) is also coated to ensure protection from the humid environment and nibbling insects or rodents. In fact, PCB can endure voltage as high as 450 volts. Inverter models can have internal stabilizer which can work within the voltage range of 198-264 volts.
Pros and Cons of Mitsubishi Electric
Starting with the pros, first one would be is that all the latest ACs come with eco-friendly R32 or R410 refrigerants. We liked that Mitsubishi has opted out of R22 refrigerant which has ozone depletion potential. Another plus is that Mitsubishi ACs can work even in the scorching summers when the temperature goes past 45oC. Mitsubishi Electric air conditioners are generally durable. All their models are made out of India and are imported. Their quality is quite good in general. In fact, they hold the Guinness World Record for being the longest running cross-flow AC brand in 2017. And thanks to this cross-flow fan and aerodynamic design they are amongst one of the quietest AC brands.
Talking about cons, major would be its limited online presence. In this digital age where every brand wants an online presence, we could spot very few models on major e-commerce platforms. Also, Mitsubishi Electric do no manufacture windows AC so those who want windows AC would be disappointed. Another problem with Mitsubishi Electric is that their service center network is not that great. One reason for that is that their market presence is less in India. Being an imported brand, their products are quite expensive, which makes it hard for them to penetrate the market. And with less penetration, their service network is also not as large as many of the big air conditioner brands. Even the parts are imported, so one should be vary of this fact before purchasing. So, it is advisable to check if there is a nearby service center before going for Mitsubishi Electric.
Barring the unavailability of windows version, Mitsubishi Electric offers ACs for varying application, from small to large, from non-inverter to inverter, from split to duct, which meets residential and commercial user’s need alike. With such a wide catalog personally, I’m still surprised that Mitsubishi Electric is not that well-known brand as its car-making counterpart.
Most of the models are free of R22 refrigerant which would be phased out soon and come with the copper condenser which is more reliable than aluminum one which makes Mitsubishi Electric a brand worth considering. So, if you have a Mitsubishi service center near your house and want your AC to cool even in the peak summer with minimal hassles go for Mitsubishi Electric air conditioners.
