Humidity control with fresh air supply ventilation

Ururu humidifying operation

Adds moisture to the air to maintain a comfortable humidity level even during dry weather.

Ururur humidifying operation

Daikin’s exclusive system requires no separate water supply,*1 so there is no need to add water and no worries about mould.

Using a humidifier unit in the outdoor unit, the Ururu humidifying operation function extracts moisture from outdoor air and uses it to raise the moisture level of the indoor air throughout the room. The system is very hygienic because there is no water tank requiring periodic refilling.

Above figures are for continuous humidification operation.
Because the Ururu Sarara uses a different humidification method from conventional humidifiers, the actual humidification volume varies depending on outdoor conditions and installation details.
Humidification volume is reduced by approximately 15% when the outdoor temperature drops by 5°C.
Humidification volume is reduced by approximately 20% when the outdoor relative humidity drops by 20%.
A humidifier hose length (piping length) of 7.5 metres is used as the standard. Extending the hose length by 2 metres will reduce the humidification volume by approximately 10%.

Moisture is added to the warm air flowing into the room, so even a large living room is humidified evenly

Humidified heating

Ururu humidifying operation is the ideal form of winter heating because it combines the functions of an air conditioner (heater) and a humidifier in a single system. The powerful humidifying function spreads warm, moisturised air evenly to every corner of the room. Humidity is maintained at the ideal level for skin that is sensitive to dryness.

Perceived warmth is heightened, helping to avoid excess heating. Humidified heating is gentle to the human body

Humidified heating

The dryer the air, the less our bodies perceive the warmth around us. Ururu humidifying operation humidifies the indoor air just the right amount so that you feel comfortably warm even at a relatively low temperature setting.

The humidity may not reach the exact level due to the effects of indoor or outdoor conditions.

Dry air is ideal for the spread of viruses. Ururu humidifying operation lets you keep the air optimally moist.*3

It is understood that the mortality rate of viruses rises when the relative humidity is 40% or higher. Ururu humidifying operation maintains the moisture in the air so that viruses have difficulty propagating.*2

*1. Household air conditioners using a humidification system not requiring a separate water supply (current as of April, 2006).

*2. Humidification capacity measurement conditions: Outdoor temperature 7°CDB, 6°C WB (heating capacity measurement conditions). Humidification capacity drops when outdoor temperature and humidity are low. Actual humidity may not reach the exact level if the ventilation air volume is high or the temperature setting is high. Maximum power consumption of humidifier heater is approximately 560 W. Level is controlled between 0 W and maximum power consumption. Operation pattern during humidifying operation may differ due to factors such as customer settings, room size, ventilation frequency, and temperature and humidity conditions.

Sarara drying operation

Sarara drying operation removes moisture from the air without lowering the temperature, keeping the indoor environment fresh and comfortable.

Sarara drying operation

When the weather is rainy or on summer nights, using the air conditioner’s cooling and dehumidifying function can end up making the air uncomfortably chilly. Sarara drying operation (dehumidifying with reheating)*¹ uses waste heat from the outdoor unit to warm the cold dehumidified air, and then sends it into the room at precisely the right temperature.

*¹. A reheating system that does not lower the room temperature, as defined by the Japan Refrigeration and Air Conditioning Industry Association.

Refreshingly dry without lowering the temperature

Sarara drying operation

The programme dry operating mode of a conventional air conditioner removes moisture by operating in a reduced capacity cooling mode. This causes the indoor temperature to drop. Sarara drying operation removes moisture from the air without lowering the indoor temperature. It is ideal for humid times such as during rainy weather when the temperature is not particularly high.

At the same room temperature, with lower relative humidity you feel cooler and fresher

Sarara drying operation

Even at the same room temperature, if the relative humidity is high you feel hot and clammy. Sarara drying operation lowers the humidity only so you feel cool and refreshed.

Dry cooling operation dehumidifies and cools the air at the same time

On hot summer days when dehumidifying alone would leave the air uncomfortably warm, the dry cooling operation mode lowers moisture and cools the air at the same time for maximum comfort.

The humidity may not reach the exact level due to the effects of indoor or outdoor conditions.
Sarara drying operation consumes more power than dry cooling operation.
