Transformation of the original residential building energy conservation technology research
In the original residential building energy-saving exterior insulation is often used technology. 2.2 The roof the roof is generally divided into energy-saving technology of flat roofs and sloping roofs of two forms, the flat roof structure is simple in form, it is the most common form of a roof. In order to improve the insulation performance of the original house roof, in the energy saving should note the following: (1) In order to improve the thermal insulation material layer, the best selection of small thermal conductivity, heat storage of large materials. Bulk density should not be selected taking into account the material is too large to prevent excessive roof loads. (2) roof insulation material identification, should be based on the thermal energy requirements of buildings to determine the thickness of insulation, but also pay attention to the arrangement of material layers, also affect the order of the different thermal performance of roof, should be based on Architectural features, climate conditions thermal design. Calculation of building thermal design based on energy-saving roof to determine the heat transfer coefficient k, the thermal resistance R and the thermal inertia index D value, so that the thermal performance of roof construction to meet energy efficiency standards. The most commonly used roofing insulation materials: polyurethane waterproof thermal insulation system, polystyrene board insulation system. 2.3 The energy-saving technology should be the window lighting, ventilation, decoration, noise, fire and many other features, therefore, in technical processing relative to other building envelope components is more difficult. Energy Saving in the window are the following: (1) increased use of air gap layer thermal transfer window; (2) to enhance thermal performance of window frame material resistance, an increase of the mass resistance, which helps to reduce the transmission window heat, air conditioning or heating reduces energy consumption; (3) the existence of walls and window frames, box and fan, fan assembly and the gap between the glass, it will have indoor and outdoor air exchange,[link widoczny dla zalogowanych], will lead to cold, heat energy increases, so must control the amount of air infiltration gap doors and windows. Currently, energy-saving windows, by the poor thermal performance of the original windows all removed, the change in the PVC with good thermal insulating glass windows or other windows to meet energy requirements, or in the original installation of the air outside the window seal, improve the air tightness of windows, but also within the original window sill outside the window installation of a window or outside to form a multi-storey windows, the original windows can also improve the sealing method, frame and fan, fan with the glass the gap adjustment processing. 3 Conclusion of the original residential buildings through energy-saving technology research, improve the existing building energy-saving summary of the technical and economic programs for the existing residential building energy saving technology to provide a reference. Existing residential buildings on the external walls,[link widoczny dla zalogowanych], windows, roof of the energy saving features to enhance the use of the building, so that after transformation, the original residential buildings can meet the national energy efficiency standards for comprehensive requirements. Energy-saving doors and windows of the indoor thermal environment issue is the quality and construction section. Base out of touch can be one of the main factors to our current building envelope components, the doors and windows of the beggar x corner building energy consumption accounts for a sizeable proportion. Therefore, strengthening doors and windows (1) Liang Guanhua. Existing residential buildings and technical characteristics of energy-saving insulation properties held, doors and windows to reduce energy consumption is to improve the quality of indoor thermal environment and improve measures the amount of 2007 * an important part of building energy efficiency standards. On the other hand, construction (2] Zhao Hong, Sun root, Jiang Jianming,[link widoczny dla zalogowanych], Zhao Jianguo change the existing residential building energy saving windows and doors bear the isolation and communication inside and outside the two environments, each made of two technology exploration and research in 2007. contradictory task requires not only that it has good insulation properties, but also Received: 2DO7-1O-29 (Continued from page 67) easy to use cracking mortar composite fiberglass mesh approach. (5) hot dip galvanized angle steel mesh four Laying flat, sun angle steel parts shall not be disconnected, overlapping mesh network edge should be angle gland, the number of expansion bolts, anchor position to meet the requirements. 5 Summary of the project powder particles of polystyrene insulation tile finishes exterior insulation system design and construction is successful. works successfully passed inspection, inspection results excellent. brick wall has no crack, fall off, hollowing, reliable insulation system, thermal insulation effect is good. the construction side is very satisfied. powder particles of polystyrene wall insulation system disadvantages are: polystyrene particles can wipe manual, low efficiency, the thickness of a wipe into a small length of insulation systems for use in molding, a long construction period, material recycling after landing hard. In short, the powder particles of polystyrene insulation Face brick exterior insulation system slurry in building applications, take appropriate safety measures for strengthening the effective resistance to heat stress, fire, water or water vapor, wind, earthquakes and other external forces directly on the surfaces of buildings to prevent ornaments cracking,[link widoczny dla zalogowanych], facing tile from the dark, shedding quality of the accident, so that thermal insulation of buildings and the stability of the system is stable and reliable. The system works good quality, good flatness, high reliability and broad market prospects,[link widoczny dla zalogowanych], high applicability . Received :2008 -01-30
