Description
Technical Field
The invention relates to the technical field of building energy conservation and building envelope structures.
Background
The ventilating air space is usually used for cooling the building in summer, for example, in the patent 2017113026094, namely, in the composite enclosure structure for the low-energy-consumption container house, the openable low-radiation air space utilizes hot pressure and wind pressure to ventilate and radiate in summer, so that the surface temperature of the air space is reduced, and the summer heat insulation of the building is improved; in order to reduce air resistance, the thickness of the ventilation air interlayer is properly increased, and the general thickness is between 50mm and 1000 mm; EN ISO 6946-2007 Calculation method of Thermal resistance and heat transfer coefficient of Building Components and Components (Building Components and Building elements-Thermal resistance and Thermal transfer-Calculation method) shows that: for a horizontal air space for upward heat transfer (such as an air space in a horizontal roof in winter) or a vertical air space for horizontal heat transfer (such as an air space in a wall), the thermal resistance thereof becomes small with the increase in thickness, particularly when the thickness of the air space is more than 15mm, due to natural convection of air between the high-temperature side and the low-temperature side wall surfaces; the thermal resistance of an air space layer, typically greater than 15mm thick, such as 15mm to 300mm, is nearly equal, with a horizontal upward heat transfer air space layer thermal resistance of about 0.16m2K/W, vertical air interlayer thermal resistance of about 0.18 m2K/W; the air space layer with the heat preservation capability is only equivalent to the heat preservation capability of a cork board or a shaving board with the thickness of 15mm, and is obviously lower than the heat preservation capability of a common building heat preservation material layer, for example, a 15 mm-thick expanded polystyrene layer has the heat preservation capability of 0.43m2K/W to 0.56 m2Thermal resistance of K/W; the thickness of the polyphenyl plate used for the building heat-insulating layer under the general condition is 50mm to 100mm, the ultra-low energy consumption building even adopts the polyphenyl plate heat-insulating layer with the thickness of more than 200mm, therefore, the heat resistance of the heat-insulating material layer with the thickness of 50mm to 200mm which is generally adopted in the building can reach 1.4 m2K/W to 7.4 m2K/W, the thermal resistance of which is far more than 0.16m of air interlayer with the same thickness2K/W to 0.18 m2The thermal resistance of K/W indicates that the ventilation air interlayer is sealed for heat preservation in winter, and the heat preservation efficiency is obviously lower than that of a common building heat preservation material layer with the same thickness; "Yizai" with patent number 2021205701319The water storage module enclosing structure with strong heat preservation and heat insulation adopts the flow blocking film or the flow blocking net as the reinforced flow blocking layer to reinforce and block natural convection, but the air volume separated by the flow blocking film or the flow blocking net is not completely separated, and still can generate certain natural convection through the pores on the flow blocking film or the flow blocking net or be mutually communicated with the pores between the inner walls, so that the heat preservation capability of the air space layer is difficult to obviously improve; therefore, the air space with the thickness of more than 15mm in the building envelope structure can become the weak point of the envelope structure for heat preservation in winter.
At present, an outer enclosure structure of an ultra-low energy consumption or near-zero energy consumption building usually adopts an air isolation film with good air tightness and doors and windows with good air tightness so as to reduce air permeation heat loss; the outer protective structure of the existing container house is made of an airtight material, such as a steel plate, and if the outer protective structure is matched with doors and windows with good air tightness, the integral air tightness of the energy-saving container house is also very good; the air tightness is improved, so that the buildings cannot provide enough fresh air to maintain the healthy breath of indoor personnel by means of air permeation, and the insufficient indoor fresh air quantity ensures that the buildings with good air tightness need mechanical ventilation in winter; in order to avoid ventilation heat loss in winter, most of the existing ultra-low energy consumption or near-zero energy consumption buildings adopt a fresh air heat recovery unit to recover a part of heat from exhaust air; the core part of the fresh air heat recovery unit is an air heat exchanger, such as a runner type air heat exchanger and the like, and the core part is provided with a cold and hot air heat exchange surface; because the size of an air heat exchanger in the existing air conditioning system limits the contact area of cold air and hot air, and the contact time in the cold air and hot air flowing is also short, the large-proportion recovery of exhaust heat is difficult to realize through the existing fresh air heat recovery unit; at present, the recovery efficiency of general exhaust air heat is only about 65%, the temperature of air at an exhaust air outlet in winter is still higher relative to the outdoor air temperature, so that the exhaust air heat loss of a building in winter is larger, and the improvement of the energy efficiency of the existing ultralow-energy or near-zero-energy-consumption building is influenced.
Disclosure of Invention
In order to solve the problems that the existing building with ultra-low energy consumption or nearly zero energy consumption, in particular to a ventilation air interlayer in a season-adjustable outer enclosure structure of an ultra-low energy consumption container house, after being closed in winter, forms a closed air interlayer with the thickness of more than 15mm, the heat preservation capability of which is obviously weaker than that of a common building heat preservation material layer with the same thickness, and after the building adopts an airtight enclosure structure, in winter, the mechanical ventilation process is limited by the contact area and the contact time of cold and hot air of an air heat exchanger in the existing fresh air heat recovery unit, so that the heat in the exhaust air of the building is difficult to recover in a large proportion, so that when the airtight envelope structure with the season-adjustable ventilation air space is applied to buildings, the invention provides an energy-saving air interlayer for exhaust foaming, which solves the problem that the energy efficiency of the existing building in winter is obviously improved in two aspects of air interlayer heat preservation and indoor exhaust waste heat recovery.
An energy-saving air interlayer foamed by exhaust gas can be used for buildings with ultralow energy consumption or near zero energy consumption, in particular to an ultralow energy consumption container house with a season-adjustable ventilation air interlayer, and the technical purpose is as follows: on the basis of keeping the season-adjustable ventilation air space to be ventilated and cooled in summer, when the ventilation air space with the thickness of more than 15mm is formed after the ventilation air space is closed in winter, the natural convection of the ventilation air space can be fully inhibited, and the heat preservation capability in winter is obviously enhanced; meanwhile, heat in indoor exhaust air can be fully recovered in winter, and heat loss of the indoor exhaust air is remarkably reduced, so that double energy-saving gains of remarkably enhancing heat preservation and recovering indoor exhaust air heat of a building with an airtight enclosure structure and a season-adjustable ventilation air interlayer are realized in winter.
