Abstract
The utility model discloses a temperature-controlled heat flow meter building enclosure structure heat transfer coefficient detector, which comprises a data acquisition and control main frame, a one-dimension hot box, a temperature sensor, a one-dimension hot box heating control box and a heat flow sensor stuck on the inner side or the outer side of a wall body. The temperature sensor and the heat flow sensor are respectively connected with a temperature acquisition circuit and a heat flow acquisition circuit of the data acquisition and control main frame; control signals of the data acquisition and control main frame are input into the heating control box to control whether a heater in the hot box to be heated or not and to maintain the constant temperature of the hot box; and the data acquisition and control main frame calculates the heat transfer coefficient of the wall body through collected temperature and heat flow data. The detector greatly reduces the detection time, improves the detection efficiency, and is slightly influenced by seasons and not limited by region and temperature; moreover, the site operation is simple, the errors of site detected values of different wall bodies are smaller than 7 percent, and the error is 5 to 15 percent smaller than that of a hot box method.
Description
Technical field
The utility model relates to a kind of heat transfer coefficient detecting instrument, especially a kind of temperature control heat flow meter building enclosure structure heat transfer coefficient detector.
Background technology
Hot case method is that the surface of wall to certain zone evenly heats in the indoor, overcomes the influence of the interior outside of body of wall meteorological condition fluctuation to diabatic process.Can make that like this wall heat transfer process is subjected to the influence of extraneous meteorological condition as small as possible, thereby reach the heat transfer steady state (SS) as early as possible.Hot case method test is not subject to seasonal restrictions, and the laboratory environment relative fixed is easy to demarcate its border factor, and test has its superiority.
Hot case method is generally adopted in domestic energy-conservation detection based on above advantage, but its deadly defect is exactly to require heating power to participate in calculating when detecting the heat transfer coefficient of building enclosure, but because the mutability of field condition, its boundary condition is difficult for demarcating, heat scatters and disappears easily, cause heating power bigger than normal, influence the accuracy of testing result.
The utility model content
It is short that the utility model technical issues that need to address provide a kind of test duration, and error is little, is subjected to seasonal effect little, and the temperature control heat flow meter building enclosure structure heat transfer coefficient detector of wall heat transfer coefficient is detected at easy to operate scene.
For addressing the above problem, technical solution adopted in the utility model is: a kind of temperature control heat flow meter building enclosure structure heat transfer coefficient detector, comprise data acquisition and main control system, the hot case of one dimension, temperature sensor, also comprise the hot case heating of one dimension control enclosure, be affixed on the heat flux sensor in the body of wall inboard or the outside, described temperature sensor is connected with the hot-fluid Acquisition Circuit with the temperature collection circuit of data acquisition and main control system respectively with heat flux sensor, the control signal of data acquisition and main control system exports the heating control enclosure to, whether the well heater of controlling in the hot case heats, keep hot case constant temperature, data acquisition and main control system calculate wall heat transfer coefficient by temperature and the heat flow data of gathering.
The described heat flux sensor back side adopts vaseline or butter and wall table closely to paste, and must not have bubble to produce.If be affixed on side within the walls, then interior wall table temperature sensor is apart from heat flux sensor 20mm, if be affixed on the wall outside, then exterior wall table temperature sensor should be pasted on the exterior wall table perpendicular to heat flux sensor stickup face.
Above-mentioned heating control enclosure also is connected with hair dryer, keeps the equilibrium of indoor temperature.
Adopt the beneficial effect that technique scheme produced to be: the application of this instrument, shortened detection time greatly, improved detection efficiency, and this instrument is subjected to seasonal effect little, there are not region and temperature limitation, execute-in-place is easy, and measuring accuracy is higher.The on-the-spot error detection value of different wall heat transfer coefficients than theoretical value less than 7%, the little 5%-15% of detection error of specific heat case method.
