Radiation device for reducing indoor air humidity

Abstract

The invention discloses a radiation device for reducing indoor air humidity. The radiation device body comprises a radiation device body, the radiation device body comprises a cold water circulation system, a radiation plate and a heat preservation layer, the middle of the radiation plate and the heat preservation layer is the cold water circulation system, a super-hydrophobic base is arranged onone side which is different from the cold water circulation system, of the radiation plate, a plurality of hydrophobic micro-grooves are uniformly distributed in the bottom of the super-hydrophobic base, needle-shaped hydrophilic bionic structures are arranged in the hydrophobic micro-grooves, the needle-shaped hydrophilic bionic structure is arranged on the hydrophobic micro-grooves randomly or at equal intervals. According to the radiation device, the problem of condensation of an existing radiation plate is effectively solved, the indoor air humidity can be greatly reduced, and the coolingcapacity of the radiation plate can be improved, the indoor comfort is guaranteed. The device is simple in structure and convenient to use, and cooling effect is relatively good and can be widely applied to high-temperature and high-humidity regions.

Description

technical field [0001] The invention belongs to the technical field of HVAC, and in particular relates to a radiation device for reducing indoor air humidity. Background technique [0002] In recent years, the radiant air-conditioning system has attracted the attention of more and more experts and scholars due to its advantages of energy saving, environmental protection, health and comfort, and has been widely used in the field of construction. The existing radiant air conditioning system is mainly composed of radiant panels, cold and heat sources, independent fresh air system and other accessories. The radiant plate is based on the heat exchange principle of small temperature difference and large surface. By passing cold water at a certain temperature, a cold radiant surface is formed. The cold radiant surface conducts heat exchange with the air in the room and the uncooled surface in the form of convection and radiation, thereby Lower the room temperature. Compared with ...

Problems solved by technology

[0003] However, the existing radiant panels have low cooling capacity and are prone to condensation, so they can only bear the sensible heat load in the room.

In order to solve this problem, it is usually necessary to configure a special dehumidification system to bear the indoor humidity load. At the same time, in order to prevent the occurrence of condensation, the water supply temperature of the system must be strictly controlled. This method not only increases the investment cost of the special dehumidification equipment, It also poses challenges to the safety of the automatic control system of the entire radiant air conditioning system

Moreover, due to the uncontrollable dew condensation phenomenon, it is impossible to open the windows in the room where the radiant air conditioning system is installed. Once the dedicated dehumidification system fails, the air conditioning system cannot operate normally, which also increases the operating energy consumption of the dehumidification system.
