In recent years, relying on technological progress as the basis of the housing industry modernization development road in our city is gradually flourishing, steel structure housing, fully decorated housing, ground source heat pump technology, no negative pressure water supply equipment and other representative in line with the direction of the housing industry modernization of new technology in our city blossomed everywhere. Their application will effectively change the traditional housing construction rely on labor, capital high input with a higher consumption of resources and energy to the extensive development of the low levels of support technology, to realize the goal of energy conservation and emissions reduction in the whole society, the transformation and upgrading of urban and rural construction mode and meet the demand of the increasing of people living is of great significance.

Steel house

Steel structure housing can achieve industrial production, standardized production, change the extensive construction mode caused by serious waste of resources, to achieve the saving of materials and land, energy conservation and environmental protection and sustainable development goals. Its specific advantages are: first, the construction period is shortened by 30% ~ 50%, reducing the construction cost, and the construction is put into operation in advance. Second, compared with the reinforced concrete structure, the building weight is reduced by about 1/3. The benefits: less seismic activity and less material. The basic cost is 30% lower than that of reinforced concrete structure. Third, because the steel strength is high, the column section is small; The effective usable area of steel structure house is 4% ~ 8% more than that of traditional house. Small column section is also conducive to parking space layout. Fourth, for buildings requiring large space at the bottom (the basement is a garage or a shop at the bottom), the advantage of large applicable span of steel structure can be brought into play, and the conversion floor can be avoided to reduce the construction cost. Fifth, the steel structure housing USES the beam and column system, the space is transparent, is advantageous to the function, the spatial flexible arrangement, is advantageous to satisfy the multi-level people's demand, conforms to the sustainable development request. Sixth, the modeling is novel, become a new selling point, to attract more consumers. Seventh, because the steel structure housing USES a large number of new energy conservation and environmental protection building materials, so it can save the heating, air conditioning and other operating costs of residents. Eight is the steel structure has a good ductility, seismic performance, can provide more safe use of space for residents.

Fully decorated houses have the advantages of direct occupancy, no interference from neighbors' decoration, professional team building, improvement of living environment quality, resource saving, bulk purchase and cost reduction. Although there are some difficulties in its development and construction, such as the influence of the north-south difference on the climate factor, market factor and acceptability of the whole decoration work summarized by the project leader of huafa new town based on years of experience; The difference of materials and construction accuracy determines the consistency of fully decorated model house and batch decorated house. The quality problem of the house which is not easy to control in advance; In the whole decoration design, the use of intelligent, environmental protection, low carbon new technology materials have confusion. However, a series of national policy guidance over the past 10 years has strongly promoted the development of the fully decorated housing market. Recently, the party central leadership and clearly put forward the development of energy-saving and land-saving housing, carry out a decoration in place requirements. The promulgation of these policies indicates that the implementation of complete decoration project in new residential buildings is the development direction of residential construction and the only way for the modernization of the residential industry. The spring of the implementation of complete decoration of residential buildings has come.

Ground source heat pump technology

Heat pump is to extract energy from nature without any pollutant emission. It is now the cleanest and economical energy mode, which has been widely concerned and valued in the global scope. Ground source heat pump (GSHP) system is a closed loop central air conditioning system which is composed of a double-pipe water system connected to all GSHP units in the building. Ground source heat pump water and ground energy (groundwater, soil or surface water) are exchanged for cold and heat sources in the central air conditioning system. In winter, the heat from ground energy is "taken out" to provide indoor heating. In summer, indoor heat is taken out and released into groundwater, soil or surface water. The ground source heat pump system has the advantages of mature technology, energy saving, safe and reliable operation, benefit to environmental protection, multi-purpose, unit noise and unit maintenance with the least interference to residents, making the building become an environment-friendly building with low consumption.

No negative pressure water supply equipment

The core technologies of the water supply equipment without negative pressure include: first, the water tank is completely sealed, free of secondary pollution of air and other organic compounds, and completely solve the safety and health of drinking water for users; Second, after the equipment is connected with the municipal pipe network, it can ensure no negative pressure on the dynamic pressure of the municipal pipe network during operation. Thirdly, the unique SDF fuzzy control technology and variable voltage conversion technology are adopted to achieve the accuracy of water pressure adjustment of users: ± 0.01mpa (to eliminate uneven cold and hot water and reduce the failure rate of water appliances). Fourth, the equipment has remote monitoring, monitoring, early warning service functions, to ensure that users water foolproof. Therefore, it has the advantages of complete closure, no pollution, no negative pressure, no technical advantage of water, water pressure stability, water safety advantages, low energy consumption, low noise environmental protection advantages, high configuration, long life quality advantages and intelligent, convenient integration advantages.
