Problems solved by technology

[0004] The purpose of the present invention is to provide a mobile thermal insulation shutter and its automatic control method. In order to solve the technical problems of poor thermal insulation, air tightness and ventilation of the glass outer window, the work of the shutter is controlled by collecting outdoor related meteorological parameters. state, and solve the technical problems that the blinds do not have the function of heat preservation and insulation, and cannot automatically control the opening, orientation, retraction, and deployment. It also solves the low thermal performance of the existing residential enclosure structure and insufficient indoor thermal comfort. The problem of high energy consumption in buildings

Embodiment 1

[0058] Example 1 see Figure 7-Figure 10 shown, according to figure 1 After installing the movable thermal insulation and thermal insulation louvers, set the threshold T of thermal insulation conditions in summer H , Threshold value T of thermal insulation conditions in winter L (step S1), T H and T L Set to 24°C and 14°C respectively, the temperature sensor 1 starts to monitor the outdoor air temperature hourly (step S2). When the monitored outdoor air temperature T 0 The average value is less than the winter operating condition threshold T for three consecutive days L , the controller 5 issues an instruction, and the shutter enters the winter mode (step S3). In this mode, the louvers rotate automatically, with the heat insulation layer 4 facing outwards and the heat insulation layer 6 facing inward (step S4), and the outer glass window 3 and the inner glass window 7 are all closed (step S5). According to the monitoring of the outdoor solar radiation sensor 2, the hour...

Embodiment 2

[0062] Example 2 see Figure 7 , Figure 8 , Figure 11 , Figure 12 As shown, the temperature sensor 1 monitors the outdoor air temperature hourly (step S2). When the monitored outdoor air temperature T 0 The average value is greater than the summer operating condition threshold T for three consecutive days H , the controller sends an instruction, and the thermal insulation shutter enters the summer working mode (step S3). In this mode, the louvers rotate automatically, with the heat insulation layer 6 facing outwards and the insulation layer 4 facing inward (step S6), and the outer glass window 3 and the inner glass window 7 are all automatically opened (step S7). According to the monitoring of the outdoor solar radiation sensor 2, the hourly solar radiation Q in with shutter action threshold Q m1 Compare (step S10), Q m1 It is set to 90% of the local average daily solar radiation in summer, and according to the comparison results, the louvers will perform three acti...

Embodiment 3

[0066] Embodiment 3, when the monitored outdoor air temperature T 0 Average between T L and T H At this time, the controller issues an instruction to enter the transition season mode. Since the weather in the transitional season is relatively comfortable, no additional heat preservation or heat insulation measures are required, so the controller sends out an instruction, the blinds are completely retracted, and the normal state is maintained, and the external windows can be opened and closed according to the personal preferences of the residents.

Abstract

The invention discloses a mobile heat-insulating louver and an automatic control method thereof. The louver comprises a window frame and louver blades in the window frame, wherein the louver blades are connected with a louver border covered at the periphery of the louver blades; the two ends of the louver border are connected with fixed rotating shafts, one end of each rotating shaft is connected with a rotating motor, and the other end is connected with a bearing; a shell of the rotating motor and an outer race of the bearing are respectively and fixedly connected with a sliding body; each rotating motor and a sliding motor are respectively connected with the rotating command output end and the sliding command output end of a CPU (central processing unit); the set input end of a calculator is used for inputting a temperature threshold value and a motion threshold value, the signal input end of the calculator is connected with a temperature sensor and a radiation sensor, and the signal output end of the calculator is connected with a controller. The controller is used for receiving calculating results of the calculator and controlling the opening degree, the opening direction, the spreading or the retracting conditions of the louver blades. The invention can strengthen the heat insulating property and the air tightness of an outer window in winter, reduce heat absorbing of the outer window in summer, ensure smooth ventilation and improve the heat insulating performance of houses.

Description

technical field [0001] The invention relates to a shutter and an automatic control method for the shutter. Background technique [0002] With my country's increasing attention to building energy conservation, the requirements for thermal performance of building envelopes are also getting higher and higher. External windows are the main area for heat exchange between indoor and outdoor buildings, and the external window load can account for 30%-40% of the total building heat load. It can be seen that improving the thermal performance of external windows is of great significance to reducing the energy consumption of building heating and air conditioning. Residential houses in hot summer and cold winter regions in our country need heat preservation and solar heat utilization in winter, and heat insulation and ventilation in summer. At present, many buildings use double-glazed external windows, so that an air interlayer with a width of about 200-300mm is formed between the inn...
