As the ambient temperature increases, the ability of the AC to deliver the required cooling decreases. Twin Motor Technology, coupled with Twin
Turbo Technology, increases the
heat exchange capacity even at very high temperatures ensuring
the ability of the machine to deliver optimum cooling.
Twin Motor Technology
Conventional AC: In a conventional AC, since there is a single motor, it runs both the indoor and outdoor fans. Hence, when you reduce the fan speed inside, even the outside fan speed decreases. This reduces the machine's ability to throw hot air outside and impacts the overall efficiency of the AC.
Quadricool TM: In Quadricool TM, there are two independent fan motors - one for the indoor fan and the other for the outdoor fan. This means that the inside fan speed is independent of the outside fan speed. And the ability of the machine to throw hot air outside remains unaffected. Thus, the overall efficiency of the machine also remains unaffected.
Twin Turbo Technology
Conventional AC: In a conventional AC, Sirocco fans are used on the inside and propeller fans on the outside. Since these fans, by design, don't throw air in both directions, their efficiency is lower. Also, due to the presence of a large number of blades, the air-cutting noise is very high. Thus resulting in high noise levels and lower efficiency.
Hitachi Window Air-Conditioner: Turbo fans are designed to throw air in both directions and can provide higher airflow at lower RPM. Also, due to lesser number of blades, the air cutting is less. Hence, the use of Turbo fans both inside and outside increases overall airflow leading to higher efficiency at lower noise levels.
Auto Climate Technology
Human comfort is a combination of many factors, as depicted on the right. For example, in Delhi, the month of June is the peak of summers and temperatures touch close to 44˚C with a humidity level of 60%. Whereas in Mumbai, at the same time of the day and the month, the temperature is around 35˚C with a humidity level of 85%.
In a regular AC, you can control these factors by changing the temperature and regulating the fan speed. But this presents you with more than 50 different combinations and choosing the correct option for optimal efficiency and comfort becomes extremely cumbersome.
That's why we developed Auto Climate Technology (ACT) which is a super-advanced intelligent feature that has temperature and humidity data of over 100 cities fed into it. The AC recognises which city you are in, the time of day and your individual metabolic needs (to be chosen by you). Based on these factors, it continuously changes the settings of the AC to provide you the most comfortable environment, while functioning most efficiently, at the touch of a button.
On/Off Timer With Advanced Start-Up
On/Off Timer With Advanced Start-up: You set the temperature that you want at the given time. The AC is smart enough to scan the room an hour before the set time. It calculates the time it'll need to reach the desired temperature, and switches on accordingly. So you get the perfect comfort level as soon as you come back, without wasting any electricity.
Extra Heat Exchanger (XHE)
Window ACs are air-cooled. While Hitachi ACs are also air-cooled, there is an Extra Heat Exchanger attached to the coil which is cooled by the condensate water. Water-cooling is more effective than air cooling. Hence, with this Extra Heat Exchanger, the ability of the machine to throw hot air outside increases as compared to only air-cooled machines. Thus enabling the AC to operate efficiently even at very high ambient temperatures.
Uniform Air Distribution
The innovative air delivery mechanism enables spiral air flow, creating a ‘whorl’ effect, ensuring that there are no hot air pockets.
Is your AC being misused in your absence? If yes, just switch to the Digilock. It locks your AC and prevents the misuse in your absence, without affecting your comfort settings.
Does your AC bill enrage you more often than not? Power index on the control panel indicates the relative power consumption at different AC settings, enabling you to save power and lower your electricity bill.
Does your air-conditioned bedroom get too cozy for you to leave the bed every morning? Hitachi ACs come with an inbuilt alarm combined with an ‘off’ timer. It ensures that your busy day doesn’t start late.
Conventional air-conditioners have preset modes, whereas Hitachi air-conditioners allow you the flexibility of three programmable comfort modes to ensure that you get perfectly customised cooling.
In this, the AC works at its maximum, so as to maximise cooling. This function is available in auto & cool mode.
Auto Fan Speed
The fan speed is automatically adjusted for comfort, depending on the running state of your air-conditioner, i.e., if the compressor is cut off, the fan speed automatically comes down to low level and vice- versa. Similarly, once the set temperature is achieved, the fan speed comes down to a low level to optimise your comfort level.
This unique anti-bacterial filter prevents bacterial growth in the air-conditioner thus increasing the efficiency of the air-conditioner.
Auto Power Save Mode
The device will automatically select the comfort temperature and will maintain the temperature at about 25˚ C with suitable fan speed.
Lower Pull Down Time
The unique air delivery system and the Twin Turbo fans ensure a wider area of cooling at a faster rate reducing the pull down time. So the required temperature level is achieved at a much faster rate, as compared to conventional ACs.
Ever woken up feeling chilly in the middle of the night? ‘Kaimin’ adjusts the temperature automatically through the night to suit your body needs. It is an intelligent feature that ensures you get sound sleep every night and wake up feeling fresh every morning. By raising 1˚ C per hour for upto 4 hours, its operation ensures saving of power.
Filter Clean" Indicator
The filter clean indicator indicates when to clean the filter through an LED on the indoor unit. So in your busy schedule you can ask somebody to get it cleaned so that the AC can deliver its maximum cooling always.
Selectable Fan Speeds
The air-conditioner comes with selectable fan speeds to give you perfect comfort to suit your needs.
In high humidity conditions you can switch to dry mode, wherein the fan speed of the machine automatically becomes low which helps in removing moisture.
Here the AC works most silently. This function is available in Auto, Cool and Fan mode.
