Background

Under the background of global warming and energy shortage, building energy conservation with high energy efficiency and low emission as the core plays a crucial role in realizing energy safety and sustainable development of the country. The passive low-energy-consumption building is a building constructed by combining various passive energy-saving means such as natural ventilation, natural lighting, solar radiation, indoor non-heating heat source heating and the like with the external protective structure heat preservation and heat insulation energy-saving technology by fully utilizing natural environment and resources. Two significant characteristics of passive low-energy-consumption buildings are that firstly, the comfort of indoor environment is significantly improved, including indoor thermal comfort (temperature, humidity and air flow rate), indoor air quality, indoor noise level, indoor lighting level and the like; secondly, the energy consumption of the building can be greatly reduced, and the aim of building energy conservation of more than 90 percent is achieved. The passive low-energy-consumption building is developed and popularized, the dependence on an active mechanical heating and refrigerating system is furthest eliminated by greatly reducing the heat/cold load of the building on the premise of ensuring the comfort of indoor environment, the heating and refrigerating energy consumption of the building is further reduced, and meanwhile, renewable energy sources are fully utilized so as to eliminate the dependence on the traditional fossil energy sources, so that the passive low-energy-consumption building becomes an important means for leading the energy conservation and emission reduction of the state in the international building energy conservation technology.

The main key technologies for passive low-energy building applications include: 1. the outer heat preservation system of the outer envelope of efficient non-transparent: the heat transfer coefficient K of the roof, the outer wall, the ground or the top plate of the non-heating basement is less than or equal to 0.15W/(m)²K); 2. efficient outer door and window system: the total solar transmittance g of the glass is more than or equal to 0.35, the selectivity coefficient S of the glass is more than or equal to 1.25, and the heat transfer coefficient K of the whole window is less than or equal to 1.0W/(m)²K) glass heat transfer coefficient K is less than or equal to 0.8W/(m)²K) profile heat transfer coefficient K is less than or equal to 1.3W/(m)²K); 3. ventilation system with high efficiency heat recovery device: sensible heat recovery efficiency is more than or equal to 75 percent, total heat recovery efficiency is more than or equal to 70 percent, and ventilation power requirement is less than or equal to 0.45W/(m)³H), the internal air leakage rate is less than or equal to 2 percent, and the external air leakage rate is less than or equal to 2 percent; 4. good building air tightness measures: the method comprises the following steps of (1) setting a building integral air-tight layer, setting a window and wall sealing structure and setting sealing structures of various pipeline openings; 5. the design concept of no heat bridge and the construction mode of the building node are as follows: the anchoring technology of connecting the heat-insulating material with the thickness of more than or equal to 250mm to the bearing wall, the connection technology of the balcony and the main structure without a heat bridge, and the processing technology of the key node structure; 6. the external thermal insulation fireproof technology of the high-thickness external wall: the heat conductivity coefficient lambda of the fireproof material is less than or equal to 0.045W/(m.K), the fireproof material does not spread, does not drip or release toxic gas when meeting fire, and the fireproof isolation strip is arranged on the horizontal surrounding type fireproof isolation strip or three sides of the door and window opening; 7. moisture and water proofing; 8. and (4) noise protection measures.

However, the prior art cannot comprehensively and effectively solve all the problems.

Different from common buildings, the design, construction and operation of passive low-energy-consumption buildings adopt a functional design method, a refined construction method and an intelligent operation mode to implement by taking indoor environment indexes and building energy consumption indexes as constraint targets, so as to realize refined design, refined construction and refined operation.

The quality of passive low energy building projects relates to design quality, material/product quality, equipment quality, construction quality and operation quality at the same time. Therefore, for passive low-energy-consumption building projects, the dynamic management of the whole process is implemented by using a whole-process quality control system and taking an energy efficiency target (namely, a building energy-saving effect) and a comfort target (namely, a building operation effect) of a control building as a core, so that the realization of an expected target is ensured.

In the prior art, CN 104597884A discloses a building energy saving system, a data acquisition module is used for acquiring indoor and outdoor original data information, and transmitting the information to a data processing terminal through a data transmission module; the environment acquisition equipment is arranged in the building and used for acquiring environment parameters in the building; the data transmission module is used for transmitting the acquired data information, and the energy consumption equipment state acquisition module is connected with the data processing terminal.

However, such as the above prior art, only a single energy consumption monitoring system is involved, so as to achieve the effect of monitoring the building energy consumption or the indoor environment in the operation stage; the quality level of the construction project cannot be controlled in the whole process from the aspects of planning, designing, tendering, construction, detection, acceptance, delivery and operation, and even only aiming at the operation stage, the comprehensive control in multiple aspects cannot be realized from the aspects of long-term quality, long-term air tightness, user satisfaction and the like of the construction project.

The energy-saving mechanism of the passive low-energy-consumption building is as follows: the indoor and outdoor temperature difference heat transfer of the building is reduced through an external protective structure without a heat bridge and with excellent heat insulation performance, the solar radiation of the building is adjusted to obtain heat through the Low-E coating technology of external window glass and an effective external sunshade facility, the indoor and outdoor ventilation and permeation heat transfer of the building is reduced through good air tightness measures of the building and a fresh air system with efficient heat recovery, and meanwhile, the heat dissipation of non-heating heat sources of indoor personnel, illumination, equipment and the like is effectively utilized, so that the building can maintain proper indoor thermal comfort level under extremely Low auxiliary heating and refrigerating load/energy consumption.

Among the energy-saving mechanisms, an external enclosure structure with superior thermal performance, an effective external sunshade facility and good air tightness measure belong to the energy-saving technology of building enclosures, and a fresh air system with a high-efficiency heat recovery function belongs to the energy-saving technology of equipment. It follows that the energy efficient operation of passive low energy buildings is a result of the co-operation of the building envelope and the ventilation equipment. Under the operation mechanism, the annual heating demand of the passive low-energy-consumption building is not more than 15 kWh/(m)²A), one tenth to one fourth of the ordinary energy-saving buildings, the annual total primary energy demand (including the primary energy demand of heating, refrigeration, ventilation, domestic hot water, lighting and household appliances) not exceeding 120 kWh/(m)²A). On the basis of the passive low-energy-consumption building, the building with zero energy consumption and even an energy production room can be built by further utilizing renewable energy sources.

The ventilation and air-conditioning integrated machine system with the efficient heat recovery device operates according to the following modes:

(1) a comfort mode. The comfort control is carried out on the indoor environment according to the highest sanitary and health standard. In the aspect of air source use, outdoor fresh air is used as far as possible to bear the requirements of indoor cooling and heating and pollutant concentration reduction. The air flow is organized such that fresh air first enters the bedroom, then flows to the living room, and finally is discharged from the bathroom to the outside. The use of circulating air is avoided as much as possible, and the cross contamination caused by wind cross among bedrooms is reduced to the greatest extent.

Under normal working conditions, when the temperature is within a set range of +/-2 ℃, or PM_2.5The concentration is 50-115 mu g/m³Floating, or the relative humidity is more than 70 percent, or the carbon dioxide concentration is more than 1000PPM, and the system only uses fresh air with adjusted temperature (when needed) to optimize the indoor air quality.

In the aspect of air source use, indoor circulating air is used as far as possible to bear the requirements of indoor cooling and heating and pollutant concentration reduction. And only when the concentration of the carbon dioxide exceeds the standard or the minimum ventilation volume per day needs to be met, fresh air is conveyed indoors. The air flow organization of the circulating air is that the circulating air is taken from the living room, is sent to the bedroom after being filtered and temperature-regulated, and then flows back to the living room. In this mode, the pollutants in each area are mixed together and diluted together in the apartment complex, with the risk of cross-contamination. But as the circulating air is also filtered, the basic hygienic requirements can be met.

Under normal working conditions, when the temperature is within a set range of +/-2 ℃, or PM_2.5When the concentration exceeds the standard, or the relative humidity is more than 70%, the system utilizes the circulating air as an air source to improve the indoor air quality, and whether the fresh air is mixed depends on the concentration of carbon dioxide. When the indoor temperature exceeds the set value +/-2 ℃, or the relative humidity is more than 80%, the unit adopts the maximum cooling heat, namely fresh air and circulating air, so as to quickly adjust the temperature and the humidity.
