Below in conjunction with the drawings and specific embodiments, the utility model done a nearly step detailed description.
As shown in Figure 1, the hardware of large-scale printing opacity enclosure structure heat transfer coefficient test set forms primarily of environmental chamber 5, hot case 1, test specimen frame 2, ice chest 3, lifting equipment 8, wherein hot case 1 is also referred to as " heat death theory case ", because all temperature points and power measuring point are all placed on hot case 1 side, relative ice chest 3, except the function that hot case 1 forms specific temperature field and velocity field except having, in addition it is also necessary to complete the metering effect of whole test process; In addition, software aspect, test set also has automatic control program and data acquisition program. In Fig. 1, Q1For by the heat transfer capacity of test specimen, Q2For passing through the heat transfer capacity of test specimen frame, Q3For passing through the heat transfer capacity of hot box body, QPFor keeping adding heat needed for specific probe temperature.
(1) environmental chamber
Environmental chamber 5 is available to the stable space that equipment runs. Size is about long 11m, wide 6m, high 7m, material is assembled by the expansion polyphenyl plate color steel that thick 200mm is thick, inner installation two vertical DC convertible frequency air-conditioners and two hanging-type DC frequency converting air-conditioners, intersect at diagonally opposing corner respectively and install, install speed governing ceiling fan simultaneously at top, form a little Room air distribution design system with the centrifugal blower fan 12 bottom hot case, have more uniform temperature in environmental chamber to ensure. During test, by the air temperature control of environmental chamber to identical with air themperature in hot case, can by by the heat transfer capacity Q of hot box body3Falling is 0, will greatly improve the accuracy of test result like this.
(2) hot case
Hot case is used for simulating printing opacity building enclosure indoor climate condition, and hot case is set to movable-type, and electric structure is installed in bottom, spreads guide rail in the square hole dug, and facilitates hot case to move forward and backward, installs large-scale and super-huge building curtain wall for convenience and provide possibility. The casing of hot case 1 is assembled by the expansion polyphenyl plate color steel that 200mm is thick so that the thermal resistance of casing self is greater than 5m2K/W. It is provided with electric heater in hot case, air themperature constant temperature in hot case can be ensured by automatic control system. Simultaneously, the air current composition system being made up of adjustable speed fan 6 and adjustable air port 7 also it is provided with in hot case, can greatly reduce well heater in hot case, heat the air themperature gradient caused, make in hot case relatively more even along the temperature field in height direction, ensure apart from mean wind speed in the 50mm plane of surface, test specimen frame hot side within the scope of 0.2 �� 0.1m/s. Vertically arranging three layers of thermopair in hot case 1 as air measuring point, every layer is evenly arranged 4. Except that face contacted with test specimen frame, the inside and outside both sides in other 5 faces of hot case 1 arrange some surface temperature measuring points respectively. The one side of hot case has door, facilitates the turnover of people and the carrying of small-size test piece.
(3) test specimen frame
Test specimen frame side is fixedly connected with ice chest, and another side and hot case closely cooperate. Test specimen frame 2 is used to installation test specimen 4, and the framework of test specimen frame 2 adopts the thick expansion polyphenyl sandwich board of 400mm so that the thermal resistance of framework self is greater than 8m2K/W. As one innovation, test specimen frame is set to can directly assemble test specimen, it is possible to be equipped with the insulation plugging material of different size, with the test of satisfied different size size printing opacity building enclosure. When test specimen size is less than test specimen frame, seal after adopting the lagging material shutoff of heat transfer coefficient close with specimen thickness, known to clog. Meanwhile, paste the temperature point of some amount in lagging material both side surface, measure the mean temperature difference on two surfaces, to calculate the thermosteresis by this lagging material.
(4) ice chest
Ice chest 3 lands installation, and casing is assembled by the expansion polyphenyl plate color steel that 200mm is thick so that the thermal resistance of casing self is greater than 5m2K/W.
