Anti-condensation directional radiant cooling device

Abstract

The invention discloses an anti-condensation directional radiant cooling device. The anti-condensation directional radiant cooling device is characterized by comprising a heat preservation frame, a radiant panel, metal pipes, connecting parts, a long-wave radian transmission layer, a closed air layer, a shutter and a control device; the upper surface of the radiant panel makes close contact with the inner surface of the heat preservation frame; the lower surface of the radiant panel makes direct contact with the closed air layer; the metal pipes can be arranged on the upper surface and the lower surface of the radiant panel and are connected to the radiant panel through connecting parts; the shutter is arranged in the closed air layer; and the long-wave radiation transmission layer is located below the closed air layer and separates the closed air layer from indoor humid air. According to the anti-condensation directional radiant cooling device, directional radiant cooling is realizedthrough a built-in shutter structure, the load and energy waste of an air conditioning system are reduced, and accurate energy consumption is realized; and by means of the built-in shutter structure,the air flow resistance of the closed air layer is increased, the natural convection process of the closed air layer is weakened, and the anti-condensation effect of the radiant panel is improved.

Description

technical field [0001] The invention relates to a terminal device of an air-conditioning system, in particular to an anti-condensation directional radiation cooling device. Background technique [0002] The radiant air conditioning system has been paid more and more attention due to its potential to improve the comfort of the indoor environment and realize the energy saving of buildings. However, in order to avoid condensation on the surface during cooling, the existing radiant air-conditioning system needs to strictly control the temperature of the radiant cooling surface to be higher than the dew point temperature of the indoor air, which restricts the improvement of the cooling capacity of the system. Therefore, the radiant air-conditioning system often only bears part of the sensible heat load, and the ventilation and dehumidification system is required to jointly supply cooling and bear the latent heat load. At the same time, the existing radiant air-conditioning syste...

Problems solved by technology

[0004] In the prior art, the radiant air-conditioning system often provides indiscriminate radiant cooling to the room, and does not have the function of directional radiant cooling, and the effective utilization rate of radiant cooling needs to be further improved.
