Embodiment Construction
[0011] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:
[0012] See attached figure 1 As shown, the structure for implementing this method of preventing dew condensation on the outer surface of the thermal insulation pipe in the suspended ceiling is: in the space above the suspended ceiling 7 of the house, an air dew point temperature sensor 5 is installed, and an air dew point temperature sensor 5 is installed on the outer surface 8 of the thermal insulation pipeline in this space. A temperature sensor 4 is provided on the suspended ceiling 7 to connect the space above the suspended ceiling 7 with the living room space of the house below, and an electric valve is set on the vent 2. The duct 10 passes through the space above the suspended ceiling 7, and a communication port 3 is set on the return air duct 10 to communicate with the space above the suspended ceiling 7. An electric v...

The invention discloses a method for preventing the outer surface of a thermal insulation pipeline in a hung ceiling from condensation. According to the method, the hung ceiling (7) of a house is internally provided with an air dew-point temperature sensor (5). A temperature sensor (4) is arranged on the outer surface (8) of the thermal insulation pipeline. A ventilation opening (2) which makes the inner space of the hung ceiling (7) communicate with the outer space of the hung ceiling (7) is formed in the hung ceiling (7). An electric valve is arranged in the ventilation opening (2). In addition, an air-returning pipeline (10) of an air conditioner unit (9) in the house penetrating through the space above the hung ceiling (7), a communicating opening (3) is formed in the air-returning pipeline (10) and communicates with the inner space of the hung ceiling (7), an electric valve is arranged in the communicating opening (3), an air-returning opening (1) of the air-returning pipeline (10) is formed in the hung ceiling (7), and an electric valve is arranged in the air-returning opening (1). Temperature signals of the air dew-point temperature sensor (5) and the temperature sensor (4) are transmitted to a controller (6), and start and stop movements of the communicating opening (3), the ventilation opening (2) and the air-returning opening (1) are controlled by the controller (6).
Description
technical field [0001] The invention relates to a method for preventing dew condensation on the outer surface of a thermal insulation pipe in a suspended ceiling, and belongs to the technical field of building structures. Background technique [0002] With the development of the national economy, the application of air-conditioning systems in both industrial buildings and civil buildings is becoming more and more extensive. The problem of dew condensation on the outer surface of the insulation pipe is also gradually emerging. Not only is the outer surface of the insulation pipe in the suspended ceiling prone to condensation in areas south of the Yangtze River such as Chengdu and Guangzhou, but similar problems will also occur in northern areas such as Xi'an. [0003] When the temperature of the outer surface of the insulation layer in the ceiling is lower than the dew point temperature of the air in the ceiling, condensation will occur, and the condensed water will cause th...
