Micro-convection cooling and radiation heating ceiling device
The invention discloses a micro-convection cooling and radiation heating ceiling device which comprises a heat preservation board, a ceiling board, a connecting board, a coiled pipe and a draught fan. The outer edge of the ceiling board is connected with the outer edge of the heat preservation board through a connecting body to form a sealed space. A convection gas inlet and a convection gas outlet are formed in the ceiling board. The upper end and the lower end of the connecting plate are connected with the heat preservation board and the ceiling board respectively. The sealed space is divided by the connecting plate into a circulation space and an exchange space for heat exchange. A circulation gas inlet and a circulation gas outlet are formed in the connecting plate. The coiled pipe and the draught fan are arranged in the exchange space. By arranging the heat preservation board on the ceiling board to achieve thermal insulation, heat transfer waste is reduced; meanwhile, by achieving convection rapid heat exchange through a convection channel and achieving radiation heat exchange through a circulation channel, the flow of a working medium in the coiled pipe and the air volume of the draught fan are reduced during radiation heat exchange, the indoor comfort level is increased, and meanwhile energy consumption is lowered; in addition, the temperature difference between the upper side and the lower side of the ceiling board is small through convection heat exchange in the early period, and therefore dew formation can be effectively avoided through radiation heat exchange in the later period.
