The radiant air conditioning system is based on both radiant heat transfer and convective heat transfer, with radiant heat transfer as the primary mode. In summer, the chilled water produced by the cooling source is conveyed to the radiant panels through pipelines, causing the surface temperature of the panels to drop and releasing cooling into the room. In winter, the hot water supplied by the heating source is delivered to the radiant panels through pipes, raising the surface temperature of the panels and releasing heat into the indoor air.
The core advantage of radiant air conditioning lies in using radiant heat exchange as the primary method of temperature control, distinguishing it from traditional air conditioning which relies on forced convection airflow. Large-area radiant panels (such as capillary radiant panels or metal radiant ceiling panels) create a stable temperature field, and heat is transferred directly between the human body and the radiant panels through radiant heat. It feels like being in a naturally comfortable environment, without the strong airflow from traditional air conditioner vents, avoiding discomforts such as dry skin and headaches caused by 'air conditioning wind'.
In terms of temperature uniformity, radiant air conditioning can achieve precise control of the entire home's temperature, with vertical temperature differences kept within 2°C-whether near the floor or under the ceiling, the temperature is almost identical, avoiding the common discomfort of traditional air conditioning such as "hot head, cold feet" or "cool upstairs, warm downstairs." At the same time, the system's terminal radiant panels do not require fans, so there is no noise from mechanical operation during use. Indoor noise levels can be reduced to below 30 decibels, close to the quiet standard of a library, creating a tranquil and comfortable environment for rest and work.
The radiant air conditioning system adopts a scientific "temperature and humidity separation control" design, where temperature adjustment is handled by the radiant panels, while humidity control and air purification are fully managed by an independent fresh air system. The fresh air system precisely adjusts dehumidification or humidification based on the number of people indoors and air quality, keeping indoor relative humidity stable within the 40%-60% comfort range. This avoids the excessive dehumidification of traditional air conditioning that can lead to dry air and respiratory discomfort, as well as prevents high humidity issues that can cause wall dampness or furniture mold.
Unlike traditional fan coil air conditioning, radiant air conditioning does not have the 'hygienic dead spot' of an indoor condensate tray-traditional fan coil units produce condensate when operating because the coil surface temperature is lower than the air dew point, leaving the condensate tray constantly damp, which makes it very easy for mold and bacteria to grow, and they can spread through the air throughout the room. In contrast, the surface temperature of a radiant panel in radiant air conditioning is always higher than the indoor air dew point (with humidity controlled in advance through fresh air dehumidification), so no condensation forms, fundamentally eliminating the environment in which mold can grow.
In addition, the fresh air system uses a low-speed displacement air supply mode, where fresh air is evenly delivered from air outlets on the floor or walls at a low speed, forming a 'fresh air lake' indoors that gradually rises and replaces the room's stale air (such as carbon dioxide, formaldehyde, TVOCs, etc.), eventually being expelled through exhaust vents at the top. This air supply method has a low wind speed and no turbulence, which ensures continuous freshness of indoor air without causing a draft, further enhancing comfort and health indoors.
