                  Lu Sen fresh air system 

            In the environmental deterioration of respiratory health today, fresh air, almost become a luxury, we must rely on modern science and technology, improve indoor air quality by using fresh air system, from simple air purifier to fresh air system to change the quality of indoor air, people are changing the understanding of indoor environmental purification treatment. At present, health, comfort, environmental protection, fashion philosophy of life has become a new Home Furnishing propositions of modern life, people not only pay attention to beautiful decoration style, fashion, but also on the interior decoration materials, environmental protection, health, comfort requirements not one less. So how to achieve real sense of health and environmental protection? The emergence of Luson central fresh air system, help mankind to realize the true sense of the environmental health Home Furnishing living the dream. The environmental health of Home Furnishing life refers to indoor air quality standards, no pollution, Home Furnishing product environmental health, health and environmental protection to achieve the true sense, if the indoor air is not fresh, in the luxurious decoration in vain. This is enough to reflect the importance of indoor air quality on Home Furnishing life, indoor fresh air is to human health protection, is the human survival conditions of material.

          Lu Sen fresh air system is composed of a fan, air inlet, air outlet and pipe and joint. Installed in the ceiling inside the fan through the pipeline is connected with a series of air outlet, fan start, make indoor form negative pressure, the indoor air polluted by the air outlet and a blower and exhaust to outdoor, outdoor fresh air through the installation of the window frame above (between the window frame and the wall) of the air inlet into the interior, so that indoor people can breathe the fresh air quality.

           

             First, the principle of:

            Lu Sen fresh air system is based on using the special equipment in the indoor side closed to send fresh air into a room, and then from the other side by special equipment discharged to the outside of the room, the formation of "principle of the new wind flow field" will be in the room, so as to meet the need of indoor fresh air ventilation. The implementation scheme is: the high head, large flow of small power DC brushless high speed motor driven centrifugal blower, rely on mechanical strength by a lateral indoor air, exhaust air from the other side by specially designed machines to outdoor discharge way force to form new wind flow field within the system. In the air at the same time, the air entering indoor into the fresh air filtration, detoxification, sterilization, oxygenation, preheating (winter). Exhaust through the host and fresh air heat recovery exchange, most of the energy recycling back by fresh air indoor. Borrow the formation of large-scale clean space programme, to ensure access to indoor air is clean. In order to achieve the purpose of purifying indoor air environment.

           Two, advantage:

          one. do not have windows to enjoy the fresh air of nature;

          two. to avoid "air conditioning disease";

          there. avoid moldy furniture, clothing;

          four.remove harmful gas long-term sustained release of interior decoration, beneficial to human health;

          five. adjust the indoor humidity, save on heating costs;

          six.effectively remove indoor all sorts of bacteria, virus;

          seven.ultra quiet.

            Three, background:

           In Scandinavia area of North Europe to pay attention to quality and energy conservation in the country, central fresh air system (VMC) there has been 50 years of history. The 70's Spanish for more than 90% of the new residential is using the VMC system. In 1989 America ASHRAE formulated the "indoor air quality and ventilation specification". In Germany, residential ventilation system has been building and dissolved as a whole, become an indispensable and important component. In 2000, the EU unified standard residential ventilation.

          In China, indoor air pollution control was born in January 1, 2002. Disease SARS, avian influenza and tuberculosis occurred, make the world pay more attention to the indoor air quality.

            Four, type:

          one, the one-way flow of fresh air system

          The one-way flow system is the diversification of ventilation system and the formation of the Central mechanical mechanical ventilation system three major principles of exhaust and natural wind based, consisting of a fan, air inlet, air outlet and pipe and joint. Installed in the ceiling inside the fan through the pipeline is connected with a series of air outlet, the blower is started, air indoor turbid was installed in the interior of the suction inlet is discharged to outdoor through the fan, the formation of several effective negative pressure zone in indoor, indoor air continuously to the zone of negative pressure flow and is discharged to outdoor, outdoor fresh air from installed in the window frame at the top (between the window frame and the wall of the inlet) continue to indoor added,so you alway breathe the fresh air quality air supply system of the fresh air system,but not connected with an air pine,and the exhaust pipe is installed on the aisle, bathrooms, usually where the ceiling, basically does not occupy extra space

           

          two. the two-way flow of fresh air system

          The two-way flow of fresh air system is the Central mechanical mechanical ventilation system of three principles, based on send exhaust system, and is the unidirectional flow of fresh air system effective supplement. In the two-way flow system design of air exhaust host and an indoor air discharge position and a unidirectional flow distribution is basically the same, the difference is a two-way flow of fresh air is fed into the system by fresh air host. Air distributor of fresh air through the pipeline and the indoor host is connected to the host, fresh air to keep the outdoor fresh air through the pipeline into the interior, fresh, quality required to meet the daily life of the people of the air. The air outlet and the new tuyere with air adjusting valve, through the host power row and sent to achieve indoor ventilation.

           

           three, total heat exchange air system

            Total heat exchange air system is an improvement based on the two-way flow of fresh air system with heat recovery function of air supply and exhaust system based on. Its working principle and bidirectional flow the same, the difference is send wind and platoon wind is completed by the host, and the host of internal adds a heat exchange module, can fast heat absorption and heat release, guaranteeing full between the air and heat exchange. Discharge of outdoor air and indoor air to in the full heat exchange device for heat exchange, so as to achieve the purpose of recovering cold, heat, air conditioning energy saving, based on improving indoor air quality, to minimize the impact on the indoor temperature.

             four, air supply system

           Because carbon dioxide is heavier than air, so closer to the surface oxygen content is low, from the energy-saving aspects to consider, the fresh air system is installed in the ground will get better ventilation effect. From the floor or wall at the bottom outlet or air outlet of the cold air is spread on the surface of the floor, the formation of air flow organization organized; and buoyant plume away heat formed in the surrounding heat source. Because the wind speed is low, airflow turbulence flat, no large eddy current, so the air temperature of indoor work area in the horizontal direction is consistent, and in the vertical direction layer, layer is higher, this phenomenon is more obvious. By the heat source to the wake can not only take away the heat load,  but also the foul air from the work area to the indoor above, is located in the top of the air outlet. The bottom out of the air outlet, a driving force of heat and pollutant in the buoyancy and air flow organization under upward movement,so send the wind fresh air system can  provide good air quality in indoor  work area.

           Send the wind although there are certain advantages, but also have the certain application conditions. Generally applicable to places associated with the heat source of the pollution source

           Lu Sen fresh air can be summed up, household type air system (using negative pressure ventilation ventilation) suitable for use in less number of apartments, villas, the baby room and other small space crowded, activities; for more, ventilation frequency more KTV, Internet cafes and other places of entertainment, hotels, shopping malls,; room, office building, factory premises restaurants, banks, classroom, kindergarten, hospital wards, it is best to use fresh air unit, because the ventilation frequency multiple, energy loss, need to use heat recovery fresh air system.

            Six, the installation process:

           one, the first host power line connected from the switch box; using 1.5mm^2 copper core power line has no special requirements.

           two, with the screw rod will host lifting to the designated location, are demanding, flat, stability communication.

           three, and air conditioning, water pipes and other facilities of the staff, again to determine the field pipeline unimpeded or not, the outlet position whether the impact on other facilities, fine tuning system for drawings.

           four. the installation of the pipeline system, the hard tube every 150cm set a elevators, piping requirements of vertical and horizontal, each joint using PVC glue. A hose pipe, every 70cm set a elevator, elevator bolts using the whole tooth bolt.

           five, under tuyere pipe and the ceiling flush, side tuyere and the wall flush, after installation is complete without cutting nozzle, finally installed directly tuyere connection.

           six, pipeline and host; host selection of pipeline and engineering of inlet and outlet connection between the selection of reducing or funnel type reducer, seams with tin foil cloth adhesive tape fixed, requirements: adhesive tape is smooth, not wrinkled, joint to paste closely, not leakage, foil junction with tie fixed between.

           seven. and the host and the air outlet according to the drawings marked to see whether adding diagonal three, left for fan air outlet.

           eight, the host and the pipeline system after installation, contact the site electrician, cable requirements and switch mounting position determination, phone tracking Completed installation of
