Anti-condensation radiation cooling device with multiple working modes

Abstract

The invention discloses an anti-condensation radiation cooling device with multiple working modes. The anti-condensation radiation cooling device is characterized by comprising a reflecting plate (100), a first rotating connecting piece (200), a rotating shaft (300), a connecting structure (400), a second rotating connecting piece (500), a fixing structure (600), a metal pipe (700), a long-wave radiation transmitting pipe (800), sealing pieces (900) and a closed air layer (1000); the long-wave radiation transmitting pipe (800) is arranged at the outer side of the metal pipe (700), is not in direct contact with the metal pipe (700), and is coaxial with the metal pipe (700); the sealing pieces (900) are arranged at the two sides of the long-wave radiation transmitting pipe (800); and the metal pipe (700), the long-wave radiation transmitting pipe (800) and the sealing pieces (900) jointly surround the closed air layer (1000). The anti-condensation radiation cooling device solve the problem of condensation of a traditional radiation cooling system, switching between the global radiation cooling mode and the directional radiation cooling mode can be achieved, invalid radiation coolingis reduced, accurate utilization of radiation cooling capacity is achieved, and energy-saving significance is achieved.

Description

technical field [0001] The invention relates to a terminal device of a radiation cooling system, in particular to a multi-working mode anti-condensation 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, the traditional radiant air conditioning system is limited by the problem of anti-condensation during cooling, and it is necessary 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. At the same time, the traditional radiant air-conditioning system provides indiscriminate radiative cooling to the room. In addition to the indoor personnel, other irrelevant objects in the room such as walls and furniture will also be cooled, which i...
