Description
Technical field
The utility model relates to a kind of thermal property testing apparatus, particularly relates to a kind of thermal property testing apparatus of door and window.Be used for the building doors and windows field.
Background technology
Door and window is the important component part of building, is referred to as " eyes " of building.Door and window has important relation as the important component part of buildings with real estate industry.The quality of door and window directly influences the quality of building.Product on the door and window market can be divided into five classes by material at present: timber, steel, aluminium alloy, plastic and glass steel.The timber window, ornamentally all finds no fault with at its heat insulating ability, shapeable.The timber window is just moving towards superior at present, comprises high-grade timber window and aluminium alloy bag timber window.The steel casement door window, its intensity, rigidity is excellent, at present the color steel casement door window of main production.Aluminum alloy doors and windows because it has higher intensity and decorative effect preferably, are often adopted by high-end residential and large common facility.Plastic door-window is promoted rapidly in residential housing because possessing good energy-conservation, sound insulation, heat insulation, antiseptic effect and fabulous decorative effect.Eluriate through market in a few years, plastic door-window has surpassed timber window, steel (in fact, on an empty stomach) door and window as the runner who pulls away on the runway.It and aluminum alloy doors and windows who wins and who loses in market competition from now on also need be decided by market.Glass fiber reinforced plastic door and window, biggest advantage are the soundnesses of existing steel sash, aluminum window, and insulation, the sound insulation value of plastic door-window arranged again, simultaneously performance such as anticorrosion, insulation in addition.
Along with Construction Scale of Residential Building enlarges, the architectural design standard class draws back, and building energy conservation and indoor environment standard improve, and has promoted the differentiation of the development of building doors and windows production scale and product structure.Energy saving and environment friendly door and window has become market fashion.Described building energy conservation door and window refers to reach the doors and windows of buildings location design standard for energy efficiency of buildings.Determine with its technical feature and energy-saving effect.Rather than distinguish with the kind of above-mentioned various rapidoprints.Building energy conservation has three indexs to the door and window performance: i.e. the air permeability coefficient A value of the Coefficient K value of door and window, door and window and shading coefficient S.Namely can be described as energy saving door and window as long as reach this three technology requirement.
Summary of the invention
The purpose of this utility model is that heat transfer coefficient and the resistive connection of measuring door and window reveal the factor.Make the door and window of designing have excellent heat insulation property, good reliability and practicality.
The utility model to achieve the above object, a kind of door and window thermal property testing apparatus is provided, comprise protective housing, be positioned at the air conditioner of protective housing, hot case and ice chest, be separated by with the test specimen frame that bears test specimen between hot case and the ice chest, be positioned at the hot case electric heater of hot case, be positioned at wind isolation board, blower fan, ice chest electric heater and the evaporator of ice chest, be positioned at the dehumidifier of the outer hot case humidity of conciliation of protective housing, be positioned at protective housing outer refrigerating machine and data acquisition system (DAS) that ice chest evaporator cold is provided.
As above-mentioned structure, the temperature in the described protective housing is regulated by air conditioner; Electric heater is regulated in the logical superheated header of temperature in the hot case; Humidity in the hot case is regulated by dehumidifier; Temperature in the ice chest is regulated by electric heater in the ice chest and evaporator, and evaporator provides cold by refrigerating machine; The test specimen frame is used for fixedly test specimen (tested door and window); The effect of wind isolation board and blower fan is the interior air of ice chest to be produced by fixed-direction flow, make the heat that passes over by test specimen (tested door and window), the heat of the interior electric heater of ice chest, the cold of evaporator evenly spread to the interior space of whole ice chest, make the interior temperature of ice chest be tending towards even; The effect of data acquisition system (DAS) is the data in the acquisition test process, is used for calculating and the analysis of test findings.
When the air themperature in hot case, ice chest and the protective housing reaches when stablizing, electrical heating power and hot case pass to the heat sum that the heat of protective housing, hot case pass to ice chest and equate in the hot case of hot case.
Heat is the product of the temperature difference and heat transfer coefficient.The heat that hot case passes to protective housing is between the two the temperature difference and the product of heat transfer coefficient.Heat transfer coefficient is a fixed value, can demarcate by test in advance to obtain.The temperature difference can be gathered by data acquisition system (DAS), can calculate so hot case passes to the heat of protective housing.
Hot case passes to the heat of ice chest and forms by the heat that transmits by the test specimen frame with by heat two parts that test specimen transmits.
The heat transfer coefficient of test specimen frame is fixed, and is obtained by prior demarcation.The temperature difference is by the data acquisition system (DAS) collection, so the heat of this part can calculate.
Pass through formula:
Test specimen transmits electrical heating power in heat=hot case-Re case and transmits heat-test specimen frame transmission heat to protective housing, can obtain being delivered to by hot case by test specimen the heat of ice chest.
According to correlation formula, just can calculate final test findings---heat transfer coefficient and the resistive connection of test specimen reveal the factor.
Door and window thermal property testing apparatus effect of the present utility model is remarkable.
The heat transfer coefficient and the resistive connection that use testing apparatus of the present utility model can measure door and window exactly reveal the factor.For designing door and window with good reliability and practicality and providing favourable effectively accurate data to the building energy conservation aspect.
