    Suitable Ventilation Method for Home

    As a specialist in air and air conditioning, Daikin happily provides you some tips on how to ventilate your house for healthy and confident daily life.

    1. Basic Knowledge of Ventilation

    • What is ventilation?
      Ventilation is the replacement of indoor air with fresh outdoor air in order to dilute and displace the air pollutants (substances that are harmful to humans) inside a building.
    • What are pollutants?
      Pollutants (substances that are harmful to humans) include carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO), house dust, pollen, bacteria, and viruses that exist in the air of a room.
      Ventilation can be expected to dilute these pollutants and displace them from the room.
    • Why do I need to ventilate?
      ① Because ventilation dilutes and displaces pollutants in the air of a room
      In a completely closed room, air cannot easily leave the room, causing air pollutants to remain and increase in the room. This situation can impact the health of the people in the room. Ventilation is extremely important for diluting and displacing these air pollutants.
      ② Because dirty air accumulates in a room with no ventilation
      Many of the residences where you live such as houses and condominiums have a high level of airtightness, and dirty air cannot easily leave the room. When nothing is done in these types of residences, there will be insufficient ventilation, and dirty air will increasingly accumulate in the room.
    • Can’t I use the air conditioner to ventilate?

      Many people mistakenly believe that air conditioners bring air from outside the home and that this air is used to ventilate the room.

      In fact, air conditioners commonly used in Singapore residences creates a comfortable environment just by drawing air from INSIDE the room, cooling or warming it, then returning that air back to the room.
      Indoor air is not replaced by fresh outdoor air.
      In most cases, air conditioners cannot perform ventilation.

      You must ventilate in another way.

    2. Tips on Ventilation for Home

    • Opening the windows and creating an air passage

      For rooms with only one window

      When there is only one window, it is effective to open the room door and place a fan or similar device near the window.
      The most effective method is to turn the fan toward the window and let air outside the room. If the fan is directed toward the room, even though fresh outdoor air will enter the room through the window, the dirty air in the room will remain inside.

      For a room with only one window, place a fan toward the window to create a breeze.
    • Summary of Home Ventilation Methods

      Depending on your living environment, you can combine the three ventilation methods explained above:
      Opening the windows and creating an air passage.

      Want to ventilate the entire room?
      Ventilation example for a typical apartment in Singapore

      Want to ventilate the living room? (when you cannot open an entrance window)
      Open two windows facing the balcony.
      * No breeze will enter or leave when only one window is open, so be sure to open both ends to allow air to flow.

      The balcony windows should be opened at two places (both ends).

    Daikin, as a company that provides solutions with air, will continue to bring comfortable air and confidence to customers around the world while pursuing the new possibilities of air and conveying its importance.

    EXPERT VENTILATION METHOD FOR OFFICE & STORES

    As a specialist in air and air conditioning, Daikin happily provides you some tips on how to ventilate offices and stores for a healthy and confident work environment.

      Ventilation can be expected to dilute these pollutants and displace them from inside the room of a building.
    • Why do I need to ventilate?

      Ventilation dilutes and displaces pollutants in indoor air.

      In a completely closed room of a building, air cannot easily leave the room, causing air pollutants to remain and increase in the room. This situation can impact the health of people in the room.

      Ventilation is extremely important for diluting and displacing these air pollutants.

      Most air conditioners cannot perform ventilation.

      An air conditioner creates a comfortable environment by drawing air from inside the room, cooling or warming it, then returning that air to the room. Indoor air is not replaced by fresh outdoor air.
      This is why most air conditioners for stores and offices cannot perform ventilation on their own.
      It is necessary to ventilate by means other than an air conditioner.

      Offices and Stores Equipped with Ventilation Systems

      Buildings that lease space for offices and stores are generally well-ventilated. This is because ventilation equipment is specified by building code according to floor area and the number of people present. Ordinarily, building entrance doors and windows remain closed so that the office workers can work comfortably and efficiently and the customers shopping in the stores can spend their time in comfort. Large buildings may not have windows or have windows that are impossible to open. For this reason, ventilation equipment is installed to prevent stale air from accumulating in the building. When stores are especially crowded, or when many people attend a meeting in one room, opening windows and doors increases the efficiency of the ventilation equipment to actively change the indoor air. To maximize ventilation, we recommend that you first determine the type of ventilation equipment installed in your office or store and understand how it works and should be operated.

    Suitable Air for the Bedroom

    Comfortable air wraps sleeping people during the different cycles of each sleep.

    Daikin senses the heartbeat of the sleeping person, determines the sleep cycle and automatically controls the air to create the optimum environment.

    Within three or four hours after falling asleep, the body temperature drops so the air should not be too cold.
    Before waking up, the body temperature rises so the air should not be warm.
    We are studying the space which is conducive to good sleep by comprehensively controlling not only the temperature but also the indoor light and sound.

    The air that Daikin produces helps you get a good rest.

    Suitable Air for Studying

    Daikin is researching to fill the space with air that can help increase concentration for studying.

    The factors of the air that keep concentration requires the stimulation of temperature and smell.
    In fact, rather than keeping the temperature constant, the temperature continuously changes to keep people awake and heighten their concentration ability.
    Therefore, Daikin creates air which maintains people's ability to concentrate through sharp temperature changes.
    Furthermore, test results show that the use of aroma to stimulate different scents is effective for heightening concentration.
    Daikin is researching the air which improves the concentration quality by customizing temperature and smell, as well as AI and other technologies.

    Daikin fills the study room with air that enhances concentration.

    Suitable Air for the Bedroom on a Warm, Tropical Night

    Sleep is an important time to support one’s health.
    Optimum sleep has the power to improve the quality of daily life by increasing immunity and improving work productivity.
    To sleep soundly even in the heat of a hot season, I want to keep the bedroom comfortable with air conditioning.
    Continuous use of air conditioner might make the room too cold.
    However, there is also concern about the quality of sleep if the timer is used.

    Daikin does not lower the temperature, but believes that if you control the humidity steadily using the air conditioner, you could solve the sleeplessness of a tropical night even at a higher temperature setting.

    Daikin's original technology contstantly dehumidifies without cooling the air too much.
    This controls the bedroom’s atmosphere optimally throughout the night and creates a comfortable indoor environment.

    By keeping humidity level constant throughout the night, the hot season’s night in the bedroom can be filled with comfortable air.

    1. Unable to sleep well during a hot season with tropical nights
    2. If air conditioner controls the humidity well, it will be comfortable until the morning

    Suitable Air for Living Room

    Daikin developed a sensor from scratch that measures the level of relaxation in order to fill the living room with relaxing air.

    It is ""Airitmo"", a unique sensing technology that can measure the level of relaxation.
    It is a chair type sensor that can measure heart rate information just by sitting.
    There is a tube type pneumatic pressure sensor incorporated in the chair that detects minute vibrations of the body to learn the person’s heartbeat, respiration, and biographic information.
    We measure the degree of relaxation depending on the fluctuation of the heartbeat interval.
    If we can control this fluctuation with the air, we can help people relax.

    Daikin controls heartbeat fluctuation with technology that combines air temperature, humidity, airflow, cleanliness, smell and so on, and fills the living room with relaxing air.

    Suitable Air for Hotel Rooms

    The hotel is a place where various people arrive from all over the world.
    We must provide comfortable space for everyone in every room.
    However, depending on the difference of the living environment and personal preference, "comfortable temperature" varies per person.

    Daikin thought of an air conditioner that can run both heating and cooling mode in different rooms at any time, suitable to the different preferences for each guest.
    Hotels need to provide comfortable air for different guests’ individual preferences.

    Therefore, simultaneous operation of cooling and heating with one outdoor unit which has never been done before was made possible.
    The air conditioner was created to deliver comfortable air based on people’s preferences.

    By controlling the temperature to suit your individual preferences, the appropriate air in the room of the hotel will be maintained.

    1. The definition of comfortable air is different for each person.
    2. Cooling for people who feel hot, heating for those who feel cold.
    3. Simultaneous operation of cooling and heating with one outdoor unit.

    Suitable Air for the Office during Hot Season

    Since Japan established an Environmental Act to conserve electricity during the hot season, 28°C is the recommended temperature setting for the office to save electricity.
    Even though it is ideally comfortable at 28°C, the reality is that many people still consider it hot.

    The reason why it feels hot is due to high humidity.
    Through humidity control, we could achieve a comfortable environment even at a high temperature.

    By integrating "heat pump technology" cultivated through air conditioning development and original desiccant technology, it is possible to dehumidify and humidify simultaneously with ventilation.
    By lowering the sensible temperature through dehumidification, we create a comfortable office even at 28 ℃.

    By controlling not only the temperature but also humidity during ventilation, Daikin creates an office suitable for the hottest season.

    1. Ventilate and dehumidify the air.

    Suitable Air for Portait Living

    There are various shapes of Living-Dining-Kitchen, so the problems that arise are also diverse.
    For example, in the case of an open floor plan for the living and dining room, if the air conditioner was installed at the end of the living room, there is a need for better airflow to the dining room during hot season.

    Daikin believes that if you control the airflow according to the layout and activities, you can always feel comfortable at any time.

    "Ceiling-embedded cassette type with double flow" can blow air flow simultaneously in two directions and can adjust the balance of two airflows such as suppressing the airflow in one side of the room when nobody is there.

    1. Blow out two air currents with one unit and fill it with air suitable for portrait living through temperature control
    2. Airflow in two directions prevails throughout the room and you can switch the airflow balance according to your lifestyle

    Suitable Air for a Large Office

    In a large office, there are temperature irregularity in places such as near the door, under the outlet of the air conditioner, and by the window.
    Because there are plenty of people in the office, the air should be comfortable anywhere in the room.

    To eliminate temperature irregularity, it is important to let air conditioners flow all-around.
    However, conventional business air conditioners only blow in four directions which happen to create "blind spots of air current".

    Daikin blows around in 360 degrees to eliminate blind spots, minimizing irregularity in temperature.
    Furthermore, by controlling the strength of the air current, we introduce an active circulation of air flow.
    This can condition the air in a large space quickly and evenly.

    Comfortable air current fills the room with the air suitable for the office.

    1. Variation in temperature occurs due to "blind spots of air current"
    2. Condition air in the whole room quickly with active circulation of air flow
    3. After that, stay comfortable with “360-degree full circle blow”

    Suitable Air for a Living Room with Large Windows

    Rooms with large windows are bright and open.
    On the other hand, the bigger the window, the more heat radiation comes in from the outside, the temperature unevenness tends to occur near the window and causes the air conditioner to be ineffective.

    Daikin thought that the temperature irregularly caused by a large window could be solved by air flow.

    Thus we developed a function to blow airflow toward the window side.
    Ceiling-embedded cassette with single flow type and wall-mounted vertical airflow function eliminate temperature unevenness caused by thermal radiation from the window.

    Daikin firmly solves temperature irregularity with airflow and fills suitable air in the living room with large windows.

    1. Room with large windows increases direct heat contact
    2. To reduce temperature unevenness caused by thermal radiation
    3. Direct airflow is blown to the window side

    Suitable Air for Container Ships Transporting Fruits and Vegetables

    Fruits and vegetables are distributed worldwide and need to be transported through a long boat ride.

    In order to bring fruits and vegetables to the shop front in pristine condition, we need technology to keep their freshness even during long transportation.

    Daikin made it possible to suppress the respiration of fruits and vegetables to keep the freshness longer.
    This will allow ships to carry the fruits and vegetables farther for a longer time.

    The change in temperature and humidity is minimized in the refrigerated container by applying the inverter technology used in air conditioning.
    Furthermore, we inject highly concentrated nitrogen gas from the outside, so that we can control the concentration of oxygen and carbon dioxide.
    This makes it possible to suppress the respiration of fruits and vegetables, resulting in maintaining more freshness.

    In support of human comfort and food storage, Daikin’s technologies will create the appropriate air for refrigerators to carry fruits and vegetables.

    1. Container ships pass through various locations from high temperature and humidity to low temperature and humidity.
    2. The environment in the container must be maintained no matter where the ship goes.
    3. Oxygen and carbon dioxide concentration need to be adjusted.

    Suitable Air During Cool Season

    A loft-style house is a prestigous home with an open feeling.
    However, during cool season, warm air accumulates in the ceiling, and the floor area tends to get cold.

    Daikin thought that it is necessary to warm efficiently "from the top to the bottom" of the room to consider the temperature near the floor.

    "Air conditioner that warms up powerfully from the top" and "floor heating which warms from the bottom" are integrated into one unit.
    First of all, full power is used for the air conditioner to warm up quickly, when the room temperature is stabilized air conditioning operation is switched to low power with just floor heating.
    The atmosphere is analyzed efficiently and adjusted gradually.

    By integrating the air conditioner and the floor heating, the loft-style house is filled with the appropriate air.

    1. For a room where warm air accumulates on the ceiling
    2. Quickly warm up from the top and bottom
    3. Automatically switch only to the floor heating when room is warm.

    Suitable Air for Hot Season Outdoors

    Heat during the hottest season is one of the most important concerns in our country due to the large number of outdoor events.
    As a manufacturer specializing in air conditioning, Daikin confronts this challenge and is developing a futuristic outdoor air conditioner.
    To cool the outdoors, there is a method to use water evaporation such as pouring water on the street to make the area feel cool, but this futuristic outdoor air conditioner will cool the air through dehumidification with the heat exchanger.
    For conventional outdoor air conditioners used in construction sites and similar locations, only a narrow range in one direction can be cooled.
    However, Daikin’s futuristic outdoor air conditioner will provide cold air in four directions so that a radius of 3 meters can be made comfortable.

    Daikin creates a comfortable space not only inside the building but also outside with its own technology.

    Suitable Alr Indoors During Hot Season

    This is a thermograph of the sensible temperature.
    Maintaining the temperature at 28°C, 60% humidity is cooler than 85% humidity.
    This is because sweat will not evaporate if humidity is high, the temperature of the skin does not go down if it sweats further.
    Conversely, when humidity is low, the sweat tends to evaporate and the skin temperature decreases.
    Therefore, based on this fact, Daikin creates comfortable air.
    Even though many people feel hot at 28°C, with humidity control technology, it feels like the temperature is lower.

    This is Daikin's new, comfortable temperature at 28°C.

    Suitable Air for the Office

    Improvement of productivity is a major concern of various companies.

    Daikin has begun efforts to fill the office with the appropriate air temperature, humidity, air flow, air cleanliness, and aroma to increase concentration and productivity.

    If the offices are filled with air that is conducive to work, Daikin believes you will surely have a new way of working.
    Daikin collaborates with external research organizations and companies to study and achieve the ideal environment.

    It is under development with an aim for commercialization in 2020.

    Daikin will change the way of working anywhere with air.

Daikin solves various problems by creating air
that is suitable for the purpose of each space.
