Recent advancements in air conditioning systems

       Air conditioning is a multi-functional device that performs many tasks at once - cleans, evacuates, and delivers air to the room with conditioner. It uses its central plant or roof units to heat and cool the building.

         It also controls temperature, humidity, air movement, air purity, noise level, and pressure variations within the predetermined limits of comfort and health of locals or product processing.

       The air conditioning system, also known as the HVAC & R system, consists of parts and equipment that work together to place air, transport it to a climate room, and maintain the natural indoor features of a particular space within certain limits.

        The use of various sensors for large electronic devices has become a thing of the past due to advances in the field of electronics. In order to provide intelligent cooling, most leading air conditioner manufacturers use a variety of sensors and sensor technologies. Hitachi uses ground-breaking iSee technology in its latest Hitachi models (e.g. the Kashikoi series). These models use intelligent image sensor technology that ensures that all users in the room have equal cooling comfort while minimizing cool waste. The photo sensor identifies the number of people in the room, their location, their activities, etc., and then cools the room appropriately to provide the best cooling comfort. It also detects the shape and size of the space and, in order to increase cooling, improves its swing angle using the clever swing feature. The image sensor detects the number of people in a room, their location, and their activity, among other things, and then cools the area appropriately to provide maximum cooling comfort. It also detects the shape and size of the space and, in order to increase cooling, improves its swing angle with a special clever swing feature. Another useful function is that it detects a person's absence from the room for a set period of time and automatically closes it cool to prevent waste cooling. Taking a page from Hitachi, the new Daikin air conditioners have a smart human sensor that detects the presence (and number) of people in the room and adjusts the temperature accordingly.

        Similarly, Carrier's modern air conditioners have a Follow Me feature that uses a sensor embedded in the remote control. When this feature is turned on, the main room sensor in the home unit occupies the rear seat, allowing a special remote sensor to control it. AC adjusts ambient temperature based on information obtained from this remote sensor. This sensor is able to collect temperature data from even the most remote rooms of a room and transfer it to a central unit, ensuring that the room is kept at the right temperature. Blue Star air conditioners, like those in other models, have five different sensors for delivering what they call Precise Cooling Technology (PCT). PCT requires Blue Star air conditioners to adjust the temperature to a accuracy of 0.1°C.

        With the proliferation of smartphones and dozens of apps, thousands of years have been waiting for the app to do everything, including controlling their mood. Manufacturers of air conditioners have responded to this desire by building a specialized and efficient air-conditioning control system. Hitachi also led the pack with its WiFi Connect technology, which includes WiFi Direct functionality. All the user has to do is download the Hitachi app and pair it with the router. The user can manage and monitor his or her air conditioner on any part of the room once the connection is established. Best of all, even if there is no router or WiFi network, the smartphone (or tablet) can still connect to AC via WiFi Direct.

        App control is also available on Whirlpool air conditioners. The best feature of the Whirlpool app is that it balances power consumption based on usage. Additionally, the app displays a clear representation of usage, allowing users to see how many units of power their air conditioner is using. Even if your air conditioner does not have controls built into the built-in app, if your phone has an IR blaster, almost any air conditioner can be controlled by your phone without the need to download an app dedicated to a specific manufacturer.

4D Airflow with wide angle and larger fan

        Traditional air conditioners have a two-sided swing system (up and down) that distributes cool air throughout the space. However, many new air conditioners from companies such as LG, Hitachi, BlueStar, Carrier, and others include 4D (top-down + right-left) air-conditioning that pushes fresh air in multiple locations to ensure complete cooling inside the room. . This 4D swing features a horizontal and horizontal swing feature that ensures cooling near the room due to the omnidirectional air flow system.

        Louvres on Blue Star air conditioners have a wide angle to ensure that cool air is evenly distributed throughout the room without leaving the far corners of the room. Similarly, the FTKP series of Daikin air vents open upwards, creating Coanda airflow. This means that the cold air will not hit people directly, which will benefit the users. Coanda airflow provides cool, unpolluted air throughout the space. LG's new split ACs come with a larger fan and body compatibility with 4D airflow, increasing air flow and circulation up to 30 feet. As a result, the room has cooled at all angles as it is located directly in front of the AC blade.

Quick Cooling Technology That Cools Room Quickly

      When it comes to smartphones, there is a lot of interest in 'fast charging' technology; similarly, the rapid cooling technology in the air conditioner has a similar reception among HVAC enthusiasts. Manufacturers use a variety of techniques and designs to quickly cool the area.

        LG's new Himalayan Cool technology, inspired by the Himalayan landscape, re-creates the sound of the Himalayan mountain range in the comfort of your home. This mode can be activated by pressing the HCOOL button on the remote control. When the AC is turned on, it will blow fresh air at high speeds for about 30 minutes, or until the room temperature drops to a comfortable level. LG air conditioners use Himalayan Cool technology to provide faster cooling without sacrificing energy efficiency. Daikin has a Power Chill mode that uses dual flap flattening to cool the room in less than 20 minutes.

        Whirlpool Turbo Cool is available using 3D Cool Extreme and a two fan compressor. 3D Cool Extreme technology uses three vents — one at the top and two at the sides — to absorb hot air very quickly. The Premium Whirlpool models incorporate a two-compressor compressor, which is compatible with 3D Chill Extreme technology and enhances AC performance, allowing it to quickly cool the room even at temperatures up to 55°C.

Moisture control using Auto Humid Control and Dry Mode

Fig 3. Moisture Control

        Summer makes the air heater work, and as the rainy season progresses, conventional air conditioners may fail to control humidity or even water leaks. Traditional air conditioners consume extra energy and make the room cooler cold during the rainy season. Sneezing, a common cold, or even a headache may be the result of this. To keep moisture under control, many new AC models come from reputable companies such as LG, Voltas, Bluestar, Carrier, and others that include moisture removal or dry mode.

        In this regard, Hitachi is a step ahead of its competitors. In addition to the dry mode, Hitachi's advanced air conditioners have Auto Humid Control technology, which supplies temperature and humidity profile of more than 100 cities to AC CPU. It controls air conditioning based on data, and when it receives high humidity, the refrigerator cycle is accelerated to remove moisture from the room. Modern air conditioners produce dry, clean, and clean air without sticking to the inside of the room due to dry mode / moisture removal. This feature in air conditioners is important in humid areas, especially along the Indian Ocean coast.

PM 2.5, PM 1 and Anti-VOC filters

Fig 4. PM 2.5 Filter

        One of the most important battlefield for AC products is filter filtering. The reason for this is the increased level of air pollution. According to the WHO (World Health Organization), air pollution levels have skyrocketed in developing countries, particularly in India. Air pollution has recently been linked to an increase in respiratory infections such as lung cancer. The danger posed by particle pollution is said to be compared to that caused by tobacco. As a result, air filtering has become an integral part of air conditioner, and manufacturers continue to develop and develop strategies for controlling rising air pollution levels through multi-layer filters.

        The particle, or PM 2.5, is made up of tiny particles in the air that are two and a half microns wide (or even less). The micron is a measuring unit in the nucleus, with one inch equal to 25,000 microns. The main sources of particles of PM 2.5 include the extraction of vehicles, as well as the burning of wood and oil. Modern air conditioners from reputable brands such as Whirlpool and Carrier include a PM 2.5 filter that removes PM 2.5 emissions from the chamber. However, LG surpasses Whirlpool and Carrier by installing PM 1 filters, which filter particles with a diameter of 10,000 microns or less. In addition, LG air conditioners from 2018 onwards will feature special Ocean Black Protection, which will be used both inside and outside the units. This would allow air conditioners to provide proper cooling in India's humid climate, which is heavily influenced by sand, salt, industrial smoke, and pollutants.

        Due to their high vapor pressure at local temperatures, volatile organic compounds (VOCs) of living molecules quickly evaporate or gases. VOCs are generated by burning fuels such as gasoline, wood, coal, natural gas, and more. Paint, glue, and solvent residues all have an impact on the amount of VOC in the air. Many VOCs are dangerous because they mix with nitrogen oxides to produce low levels of ozone, or smoke, which contribute to climate change. Some VOCs are known to have adverse effects on the liver, kidneys, and nervous system. To extract flexible organic compounds, Midea air conditioners have an anti-VOC filter (VOC). Toxic VOCs such as formaldehyde are released by the Anti-VOC filter found in the Midea-separating AC, which ensures that air is free of such pollutants.

        When it comes to filtering, Blue Star takes an unusual approach. Premium Blue Star models incorporate cold plasma technology, which creates a natural bioclimate in the air conditioner. Because they are high in hydrogen ions and active and negative oxygen ions, they establish ionic contact with harmful bacteria and other substances in the air such as fungi, eventually rendering them useless. These bound particles grow slowly in size, making it easy to arrange seven awesome filters to trap them.

Automatically clean with iClean, Blow Clean and iCleaser

    Filters are an important part of air conditioners, and neglecting them can result in a significant reduction in cooling power. According to research, the cooling capacity of air conditioners can drop by as much as 50% if not cleaned and maintained every six months. We often neglect to clean and maintain our fans from time to time in today's fast-paced environment. However, in recent years, AC manufacturers have developed a solution to this problem. In addition to the standard solid air filters and filters available from premium AC from high-end companies such as LG, Hitachi, and BlueStar, the Network Company also has an automatic clean feature, which allows AC to clean its filter using a variety of techniques and methods. .

Copper Condenser and Anti-Corrosive Hydrophilic Blue Fin

        In the past, many AC manufacturers preferred to use aluminum condenser in most of their models to save money and lower AC prices. Aluminum conductors are less expensive than copper concerts, but rust faster. Also, repairing an aluminum condenser is very difficult, and often requires a complete replacement, so repair costs can be very expensive. Many AC brands, especially Indian ones like Voltas, BlueStar, and Godrej, have found a lot of fading using aluminum condensers in many of their models. With advanced consumer knowledge, most consumers will only buy air conditioners with copper condensers. As a result, products introduce more models with copper condenser as the demand for copper condenser grows. Hitachi, Daikin, and Haier, among other Japanese and Chinese brands, offer only copper condensers for their latest models.

        Hitachi once again takes the lead in all other areas: copper tube condenser, evaporator, and connecting pipes for new models built entirely of copper.. Additionally, high-end models like Toushi come with inner grooved copper that helps with the flow of the refrigerator quickly and efficiently. Speaking of LG, they also work on its aluminum condenser without delivering a host of models with copper condenser. In current LG models, an upgraded aluminum condenser in the form of a unique aluminum with a small rusting propensity is employed.

Dual Inverter Technology with Acoustic Jacket

Fig 6. Dual Inverter AC

        The most important innovation, digital inverter technology, pushes the limits of air conditioner technology. For decades, air conditioners using single-speed compressors were turned on or off at all times. The air-conditioning circuit is powered by a compressor, which moves the refrigerator through a condenser, compressor, and evaporator setup. When the temperature inside a room rises above a certain level, a single-speed compressor suddenly turns on - a sound that can be heard by anyone with a 20th-century air heater. However, the concept of an inverter has completely transformed the power in the air conditioning industry (as well as the refrigerator).

        So, what is inverter technology? However, to be really simple, inverter technology is similar to a car accelerator. When a compressor needs more power, it gives you more power. It gives less energy when it doesn't require it. With this technology, the compressor remains open but draws less energy or more energy depending on the temperature of the incoming air and the temperature set on the thermostat. The compressor's speed and power are changed accordingly. When it comes to inverter technology, LG, BlueStar, and Hitachi stand out. This is due to the use of dual inverter technology than standard single inverter technology. LG's 2018 air conditioners incorporate the latest Dual Cool technology. This twin inverter compressor technology gives LG an advantage over its competitors in terms of cooling efficiency, due to its wide range of performance. Compared to traditional inverters, the dual inverter-based AC has a modern BLDC engine with a wide frequency, which helps it maintain the right temperature with minimal variability. Flexible tonnage technology is used by two inverter air conditioners. As a result, ACs with Dual Cool technology with a capacity of 1.5 tons can change the tone from the bottom to 0.26 as high as 1.71 tons, depending on local conditions and user requirements.

        To compete with LG's Dual Cool technology, Hitachi air conditioners feature a modified tropical inverter system that uses the Seamless Cascade Vector DC Inverter System. Hitachi also introduced a novel concept called Dual Flow Expansion Technology to improve the coefficient of performance in both full and half (DFET) conditions. All of these enhancements to Hitachi's tropical inverter compressor improve high performance, resulting in excellent cooling even at 52°C. Hitachi sells more than half of its air heaters thanks to DFET technology, a significant percentage compared to an average of 20-25 percent.

Protection from Gas Fluid, Fridge Leaks, Rust and Fire

        There are a number of factors and factors that may affect the performance of AC. For example: power outage, refrigerator leak, rotting surface, short circuit etc. Protecting AC from jerseys of those elements is important. Therefore, AC companies should work in the safety and security environment to protect ACs from any serious or serious harm.

        In India, power outages and power outages are rampant, especially in remote towns and cities. As a major power plant, air conditioners are at high risk of fluctuations in electrical energy. If the power goes out, voltage fluctuations may occur, which may cause damage to the wind turbine. Due to their unstable operating feature, top companies like Daikin, LG, and Whirlpool are able to deal with this problem. Premium Whirlpool air conditioners have a complex voltage adjustment logic that acts as a micro stabilizer to ensure efficiency in the range from 155V to 264v, while Daikin separating air conditioners can operate at 160V to 264V diameter without stabilizer. LG leads in this category because it protects the AC from extremely high voltage — 145V to 290V.

        The refrigerator inside the air conditioner can leak due to improper installation, factory fault, or external damage. Freon is a toxic refrigerator that, if inhaled deep, can cut off oxygen from the cells and lungs. New network company models have an early warning system that detects leaks and shuts off the air cooler. At the same time, what matters

        Error code is displayed on the screen to notify visitors of leaks. LG, on the other hand, has created a technology that can monitor refrigeration rates and alert the user if the refrigerator needs to be replaced.

        The Blue Star separates the outer ACs units that were designed taking into account the harsh Indian climate. They use cast iron to produce metal bodies, which later become a powder coated with polyester. This keeps them from getting rusty and prolongs their life.

        The AC control box is at risk of fire due to excessive electrical flow or slow movement. So following high safety standards and safety standards, the modern Whirlpool split ACs come with a metal shell with a non-combustible case so that the control box avoids any fire hazard. In the same lines the Blue Star air conditioners come with a metal enclosure that encloses the main board — PCB (printed circuit board) to prevent overheating of electrical / electrical components.

 

Conclusion

         Modern air conditioners are equipped with state-of-the-art technology and components to provide comfortable cooling, based on the latest and most recent research findings. Hitachi, Daikin, and LG, among other Japanese and Korean brands, are at the forefront of AC technology, as they have eliminated obsolete and out-of-nature technology. LG has stopped making non-inverter air conditioners, Daikin has stopped using the R22 refrigerator, and Hitachi has stopped using aluminum condensers.

        Modern air conditioners provide a real "atmosphere" all year round. The new 2-in-1 ACs (Temperature and Cold) serve as a reliable companion in all weather conditions, whether it is cool in the summer, releasing moisture during heavy rains, or heating up in the cold winter. Smart sensors on high air conditioners detect when someone is in the house and automatically adjust the temperature to save electricity. The ACs' 4D air flow provides the same cooling instead of focusing specifically on the winding line. Unstable operation and automatic restart protects AC from power outages and ensures that AC restarts its normal operation without interfering with preset settings. The use of inverter technology ensures that air conditioners provide the best cooling.

          Air quality is becoming a major concern, especially in large cities, as urban sprawl and the development of new technologies. With this in mind, well-known AC manufacturers equip their units with modern air-purifying filters for all types of pollutants, germs, germs, dust particles, and odors using flawless, multi-layer filters that work in combination. Finally, premium models come with an app control feature that allows users to control their mood by simply swiping their phones.

Most air conditioners perform the following functions:

1. Make sure you have enough cooling and heat capacity.

2. Heat or cool the supply air, move or remove it steadily, clean and sanitize it, and reduce any noise produced by HVAC & R equipment.

3. Distribute fresh air throughout the atmosphere, ensuring adequate ventilation.

4. Maintain internal environmental standards such as temperature, humidity, cleanliness, air movement, noise level, and pressure difference between the conditioned room and the environment within pre-determined limits.

Factors such as the size and occupancy of the landscape, the natural features of the house to be managed, the quality and effectiveness of the control, and the costs involved determine the type and configuration of the components used to provide the appropriate features.
