If you ventilate an air-conditioned room with fresh air from the outside during a hot summer day, the humidity and temperature of the room will increase. At this point, to keep the room cool, the air conditioner will have to work at a more powerful setting to control its humidity and temperature. The air conditioner meant for human comfort cooling is having a limitation in controlling the Humidity (up to 55%).

For fresh air applications, Mitsubishi Electric’s Lossnay ventilation system uses a heat exchange technology to refresh the air within the room, it helps to maintain appropriate humidity and temperature for people to stay comfortable. Lossnay Ventilation System specifically utilizes direct fresh air after proper filtration to avoid the entry of dirt and dust particles as well.

However, if the air conditioner’s application is a critical application of Data center/Server room, then installation of precision air conditioning equipment with a built in humidifier is an effective solution to control humidity more precisely.

Size of a room or office is the most important factor to be considered when we talk about choosing an AC model. If we talk about a small room, there is no specific model or tonnage to be mentioned in particular. All that needs to be kept in mind while purchasing an AC unit, is that the capacity of AC neither should be small nor large as problems can occur in both cases. If the capacity of AC unit is small compared to the size of the room, it might struggle to achieve the intended level of air conditioning. On the other hand, if the air conditioner is too large as compared to the size of the room, then it would cool the room too quickly without removing the humidity from the air, which will leave the people present in the room too cold and clammy. Therefore, whether it be a small room or a large one, it is essential to keep the size of the room in mind while choosing the air conditioner to avoid any problems further.

It is mostly recommended to get your Air conditioners serviced within regular intervals to get optimal performance. It is advisable by most of the professionals that the service of the Air Conditioners should be done once a year or maybe twice a year.

If the AC unit tends to face some issue due to continuous exposure of dust, more foot falls, then to be on a safe side, it is advisable to get it examined every three months by the professionals.

There are a lot of factors which makes an air conditioner to be the best to be placed in the rooms. When you wish to choose the best air conditioner for a room, make sure that the AC unit gives proper cooling and helps to ensure that there is no excess energy consumption so as to avoid excessive electricity costs and to keep your house energy efficient.

Check if it helps in improving the quality of air, the AC’s reliability and durability are equally imperative. Look for an appropriate capacity as per the size of the room, choose the model as per the climate and weather conditions of the particular region. Most importantly use the advanced methods to calculate the perfect tonnage required for the room. Type of the indoor unit needs to be decided based on room orientation and end user’s seating arrangement. Generally, Split type air conditioners are used for individual cabins, 4-Way cassette units are used for local cooling effect in open work station areas, Ceiling concealed duct units are used for large areas of open work stations, and conference rooms wherein uniform distribution of cool air is required with less noise levels. Floor standing indoor units are used for lounge, and private lobby areas. For fresh air intake, Treated Fresh Air units are preferred. Ensuring the above pointers will definitely help a person choose the best air conditioner as per different room requirements.

Ceiling-cassette HVAC units are installed into the ceiling. These are centralised units which distribute conditioned air through One, two, three or four sides of the unit and best suitable for localised cooling effect. The outdoor unit of a cassette air conditioner is mounted outside, they are quicker and easier to install than conventional central systems, offer a wide range of indoor unit styles to meet the requirements of any space.

It is important to note that the Air conditioner does not produce unpleasant smell on its own. But, air conditioner can spread foul smell into the room area depending on the installation conditions and human induced activities.

There are a plenty of reasons for the cause of unpleasant odour from an Air Conditioner which are mentioned below:

If a foul, mouldy smell is observed once an air conditioner is switched on, there may be a problem with the drain duct not seeping out condensate water due to clogging. As the water not drained out, It will accumulate in the drainpipe and become a breeding ground for all kinds of fungi, bacteria, mould and other germs which creates the unpleasant smell which comes out whenever we switch on the AC system, in such a case, it is mandatory to get the AC unit cleaned on timely basis.

This kind of Dirty socks smell can also occur when the air conditioner was switched on after a long layoff period. This is because of deep seated fungal growth on cooling coil as the microbial reactions are accelerated during damp conditions of condensate water.

When someone smokes inside the house, the fumes of Nicotine/Tobacco can get mixed with the cool air supplied from air conditioner, thereby cause unpleasant smell inside room. The fine residue of Nicotine/ Tobacco can penetrate deeply into the fins of cooling coil. Once they settle down, it cannot be got rid of with routine servicing. Placement of Vinegar in bowls and allowing fresh air ventilation can provide some relief.

Whenever a burning smell is observed after turning on the AC, there may be a problem with the compressor. There is an immediate need to of calling a technician to get the AC unit fixed.

Rotten egg smell can be due to a dead animal or insect inside the AC unit. Insects, rats, and even birds often get inside the dark chambers of air conditioners and once they start decomposing, they cause rotten egg smell inside the room. This can also be due to the gas leak.

Methane gas from building sewage line entering through AC drain pipe can further spread into room area. The Corrosive Sulphur smell from sewage pipes can also get inside room area through AC drain piping.

Cooking smells from Kitchen can mix up with supply air of Air conditioner and can stay for very long periods. In case of drain piping of Air conditioner is connected with piping also carrying out the Kitchen waste, the air can get contaminated and drawn back into room area through suction effect of blower fan.

The Volatile Organic Compounds (VOC’s) present in Painting and Varnish layers can potentially create distinct strong smell inside room area for very long period. This kind of VOC smell can go down gradually by keep opening of doors and windows with proper ventilation and fresh air.

The leaking of Air Conditioners can be due to many reasons which are mentioned below:

• Inadequate Drainpipe slope: If the drain piping of air conditioner does not have adequate slope gradient of 1/100 cm, then in such case water can travel back and fall down inside conditioning area.
• Gaps in Drainpipe joints: The strength of Drainpipe joints which are joined by adhesive will gradually diminish over passage of time and there by create gaps at joints. Water can seep out from these joints and can spoil the surrounding premises.
• Short cycling of cool supply air: The water leakage can also occur in case of any obstruction presented in the path of cool supply air. If a decorative louver boxing was installed ahead of cool supply air path of Wall mounted hiwall unit, the condensation phenomena can create dew water droplets and they may fall on wall, floor and carpet surfaces thereby spoil the aesthetics. Similarly, in case of Ceiling concealed air conditioner, if there is a gap left out between duct collar and grill during installation stage, then the cool air can get short cycled and Dew water droplets created can spoil the false ceiling or nearby decorative wood section.
• Dirty air filters: Air filters are easy to get dirty. Dirty air filters can block the airflow and make it hard for the air to hit the evaporator coil. The coils will turn cold until it freezes. One day they will melt, producing excess water that is too much to hold. This process generates leakages from the AC.
• Leaking refrigerant: If the leaks are followed by blowing of warmer air than the usual, it is maybe the refrigerant. Refrigerant works to turn the warm air of the room into cool air. In this case it is important to immediately switch off the device and connect with a professional team to get the problem fixed as a default in refrigerant can be injurious to health.
• Piled up mould and fungus: One of the most common causes of leakage is clogged drainage. The culprit can be dirt, dust, and fungus that block the water to flow. The water will try to find the other way out, causing the AC to leak which might cause breathing issues if ignored.
• Old pipes: Through the years, the coat of an AC pipe can get broken. This may cause leakage. A new pipe cover can be a solution in this case, connect with a technician as soon as possible for the same for an appropriate advice.
• Incorrect installation: In case a new device starts to cause leakage, then there is an urgent need to get it checked that the AC unit is not unevenly installed. Contacting the professional team for improved installation is the only solution in this case.

Cool mode is the default or standard mode on which an air conditioner operates, with a set temperature point and fan speed selection by end user. In cool mode, the indoor air conditioner draws in hot air of room and runs it through the cooling coil by which the temperature of hot air is passed into cool liquid refrigerant flowing inside cooling coil. Thus, the heat of room air is passed into refrigerant and via compressor the heat will get released at condenser coil for passing into ambient air. As this process is repetitive in closed loop, thus, in cooling mode, the temperature of room air is gradually goes down to create cooling effect.

In the earlier times, Freon was the gas that was used for the Air conditioners. But with the rapid advancements, Environment friendly HFC refrigerants like R32 and R410 refrigerants (gas at room temperatures) started to be used frequently which increased the efficiency of the AC units and made them cost efficient.

No, if we talk about the temperature variations, low mode means more cooling and in turn leads to long running of compressor. As lower the set temperature will be, the AC compressor will work longer, which means more power consumption and higher cooling.

The inverter technology in an Air Conditioner is something that selectively changes the compressor motor speed according to home temperature demands. This variable compression speed means a smoother, more streamlined, and sustained approach to temperature delivery.

Yes, an inverter air conditioner consumes less energy when compared to the non-inverter AC as this advanced technology can regulate the speed of its compressor motor based on heat load variations inside room area. Once the room is cooled, the inverter air conditioner lowers the speed of the compressor motor up to an extent that it will only maintain the achieved cooling effect precisely between 1-2 Deg C variation. As the motor’s work is minimal during such maintenance of achieved temperature, the Inverter air conditioner consumes less power and thereby saves the energy. In comparison, the non-inverter air conditioner only runs at full speed or stop. In this method, there were two problems. One, there will be a wastage of cooling effect and as well as power. Secondly, the process of frequent start and stop of compressor motor consumes more power due to motor draws more starting current at every start. Inverter ACs have soft start with very low rush current. While the air conditioner is operational, machines draw regular current instead of sudden high rush current, which make Inverter ACs more efficient than conventional Air Conditioners.

Mitsubishi Electric has been a pioneer in the vertical transportation segment and offers a wide array of options when it comes to elevators and escalators. Mitsubishi Electric offers MRL elevator systems in different design types aimed at a wide range of industry verticals, some of which are: –

• NEXIEZ-MRL: A passenger elevator that is best suited for medium-rise building, commercial and residential building, and hospitals.

• ELENESSA: A large capacity MRL elevator that is designed for medium-rise building, hotels, hospitals, stations, and private residences.

The fact that Mitsubishi Electric machine room less elevators are preferred by renowned entities in commercial and residential spaces is a testament to how well-designed and utility-driven MRL elevators really are.

An elevator maintenance agreement is essentially a type of insurance that protects property owners from the erratic and unpredictable costs of elevator service, maintenance, and repairs by offering a fixed rate for each service.

Yes, the system can be quickly installed with no disruption to existing wall finishes or need for additional conduit. It may also be installed in conjunction with the building’s access control system (whether existing or newly installed).

Yes, elevators can be upgraded. Updating the old components allows adoption of the latest technologies and features for energy-savings, efficiency, and comfort. It is very important to get your old elevator car transformed into modern one to enhance the safety feature for passengers and better performance of the critical parts of an elevator.

Mitsubishi elevators can easily last for at least 25 years. The company’s vision is to provide a full-service product that delivers the best quality for the long term, taking care of all aspects of lift maintenance so that the end user receives a long lasting and a bright experience.

In general, with regular maintenance and timely modernization of the critical parts, elevators can have a lifespan near about 50 years as well.

There can be a whole host of reasons behind elevators getting stuck between floors. But the most common reason is power outage which are hard to be prevented. something stuck mechanically in a door or elsewhere, equipment failure, vandalism could be the major reasons.
