This project uses replacement fresh air system, the air purification mode is primary filtration, intermediate effect filter (G4), two-stage static electricity and bag medium efficiency filter (F9), PM2.5 purification efficiency > 90%, to ensure indoor air cleaning. Replacement fresh air system: fresh air is fed from the lower part of the room, filling the whole room with very low speed (no sense of blowing) and temperature slightly below the indoor temperature. Residents and other indoor thermal loads heat the fresh air and produce rising air. The warm air generated in this way flows into the nose with fresh air, and takes away the sweat and exhaust gas and other turbid gases from the human body. Finally, it reaches the top of the room and discharges from the exhaust holes, and forms a fresh air lake in the room.
In the application of indoor environmental protection coatings, the suppliers of decoration materials should be strictly screened and the VOC content of core building materials (such as sheets, coatings, adhesives, etc.) should be controlled according to "zero formaldehyde".

The project adopts ground source heat pump system, capillary radiation air conditioning system and displacement fresh air system.
Ground source heat pump system: Through a closed pipeline (called loop) buried 80-100 metres underground, Soil is used as an energy reservoir for heat extraction and heat dissipation of ground source heat pump units, and heating/refrigerating circulating water generates heat and cooling energy. By importing a small amount of high-quality energy (electricity, etc.), energy conversion can be realized, and the optimal effect of refrigeration and heating can be achieved.
Capillary network radiation air conditioning system: With water as the medium, heat (cold) is gently transmitted to the room through radiation. It can realize household control, save about 30% - 50% energy than conventional air conditioning combined with ground source heat pump, and ensure the balance and comfort of room temperature in the home. The temperature is maintained at 20 - 26 ℃ for the whole year. The indoor temperature is almost the same, and the deviation is less than 2 ℃.
Replacement fresh air system: It has functions of humidification, dehumidification and haze removal (multi-stage filtering, filtering hair, mosquitoes, etc., and filtering efficiency of PM2.5 up to 90%). The air with the most suitable temperature is exported through the fresh air outlet, and the fresh air is sent down and back to form an orderly air circulation. Without opening windows, pure air can be input uninterruptedly, and the indoor humidity effect of about 30-70% can be achieved.
The weight sound insulation of the air acoustics meter for the outer windows of residential space is more than 30dB. Facing the entrance of the aisle, the weight of the air acoustic meter is more than 25dB. The elevator shaft is not adjacent to the bedroom and living room. Sound insulation measures should be adopted when adjacent to other living spaces.
Through the comprehensive upgrading of the exterior wall enclosure, door and window system and indoor decoration, controlling sound insulation performance of floor, partition wall and doors and windows, and select low noise equipment, do a good job of air duct sealing, so that the indoor noise of residential buildings is lower than the national standard.
Using the same layer drainage system, water seal pipe fittings sharing the same layer drainage system of high-density polyethylene HDPE is used instead of many P-bends and S-bends. The overall structure is reasonable. So it is not easy to jam, and easy to clean up, dredge, with international first-line brand pipes, the noise may be controlled at a lower level, to create a quiet living environment.
