Features of floor convection device

Floor Convection DeviceMainly takes the water medium as the carrier, carries on the heating and the refrigeration. Embedded in the ground of heating and refrigeration equipment, built-in high-efficiency heat exchanger and strong mute fan, aluminum grating border. Floor fan convection can take into account the use of heating and refrigeration functions, dry/wet conditions are excellent operation., the mode of air supply is: from the bottom up. As shown on the right:

Air Supply mode

Features are as follows:
①. Air supply along the wall attached to the flow, the formation of a curtain, can effectively improve the thermal comfort of the area of personnel activities;

②. It has a faster reaction speed than a simple radiant heating;

When the ③ is tall, the airflow is made more efficient by the bottom-up mode of operation.

④ Winter warm air attached jet like car air conditioning to prevent curtain wall glass and mousse metal condensation;

⑤ choose through the fan, more mute;

⑥ can be used laminar flow Air Supply mode operation, health and energy saving;

⑦ no airway to send wind, reduce the possibility of breeding bacteria in air conditioning duct;


Floor convection device is a kind of air conditioning end, divided into natural convection type and forced convection type two kinds:

1, natural convection type built-in heat exchanger, indoor air through the heat exchanger for natural heat transfer, has reached the goal of improving room temperature, generally applicable to winter heating;

2, forced convection type built-in transverse flow fan and high-efficiency heat exchanger, refrigeration conditions through low-temperature cold water, heating conditions through high-temperature hot water. Strong convection heat transfer is carried out through the fan to adjust the indoor temperature.


1, the mode of air supply from the bottom to the upper close to the curtain wall, the formation of a curtain to prevent radiation heat transfer, efficient use of energy, reduce waste;

2, winter heating, low wind speed will be blown out of the hot air flow naturally rise, reduce the energy consumption of the fan, summer refrigeration, the cold air blowing to the height of the natural sinking, improve the cooling rate;

3, airflow tissue laminar distribution, indoor personnel without a sense of blowing, improve comfort;

4, DC brushless cross-flow fan air supply, mute effect is better;

5, landing inside the reservoir, easy to install, increase building flexibility and aesthetics;

6, grille removable, easy to maintain.



A, shielded curtain wall cold/hot airflow attack
In winter, the cold glass curtain wall cools the air near the indoor side curtain wall, making it form a sinking airflow, quickly touching the ground, invading indoors, the staff in the room feel unwell; The speed of this sinking cold air, effectively affecting the area and the amount of cold caused is proportional to the height of the glass curtain wall; the floor convection air conditioning system blows the heated air upward along the curtain wall, blocking the production of cold air flow, or shielding it near the window for the purpose of protecting the indoor thermal environment;
In summer, the floor convection air conditioning system blows up the cold wind, blocking the production of hot gas near the glass, to avoid its flow along the ceiling to the indoor interference;
B, compensation for cold/thermal radiation loss
In winter, the cold glass curtain wall will produce cold radiation to the indoor air, part of which is reflected to the human body, at this time even at the qualified room temperature, people will feel uncomfortable. This is the effect of cold radiation on comfort; Floor convection air conditioning system by heating the cold radiation zone near the curtain wall air, can offset or partially compensate for the heat loss caused by cold radiation, improve the indoor thermal comfort;
In summer, the floor convection air conditioning system improves indoor thermal comfort by cooling the air in the thermal radiation area near the curtain wall, offsetting or compensating for the extra heat generated by thermal radiation.
c, to prevent curtain wall condensation
In winter, due to the high indoor temperature, air humidity, when indoor air contact with the glass curtain wall, is rapidly cooled, resulting in water analysis on the glass curtain wall, the formation of condensation or frost. The floor convection air conditioning system avoids the condensation of the glass curtain wall by heating the air around the curtain wall and increasing the airflow flow rate. Through the following set of refrigeration conditions under the laboratory data, we can see that the use of floor convection in the room air speed is low, the temperature distribution is uniform, the turbulence rate is low, comfort relative to the traditional wind plate on the air supply mode has been improved a lot.
