Two-way flow of fresh air system bi-directional flow of fresh air system is based on three principles mechanical ventilation system central mechanical delivery, exhaust system indoor air system top ten brands, and is a one-way flow of fresh air system to effectively supplement. In the two-way flow system design is consistent with the position of the exhaust host and unidirectional flow distribution of indoor air vents, except that the two-way flow of fresh air in the system is fed by the fresh air host. Fresh Air host connected by a pipe with an air distributor chamber, fresh air hosts continued to outdoor air is piped into the room. Air vents with new outlet comes with air flow control valve, through the power row and sent the host to achieve indoor ventilation. The company has experienced designers Panasonic system solutions indoor air system, technical team and experienced professional construction team composed of professional and technical personnel to ensure the introduction of international advanced design concepts, using the global standard technical specifications, construction commissioning perform a complete, strict project management practices. Companies pursuing dedication to customer service, customer satisfaction is our purpose of operating principles, and strive to win-win cooperation, in order to satisfy customer needs. The new wind ventilators can be divided into the total heat ventilators and sensible heat exchanger two kinds. Both are played its premise the exchange of indoor and outdoor air does not consume the indoor heat under completion. Which completely switch group movement is silk paper material, heat recovery chamber, the movement of the sensible heat exchanger aluminum foil indoor air system, which can recover the indoor heat, can also be recovered indoor humidity, heat recovery efficiency can More than 70% efficiency, the heat exchange efficiency of the new wind ventilators in more than 40%, heat recovery units divided into vertical and horizontal installation. Two outlet into two, cross convection, two-way ventilation. The company has experienced system solutions designers, technical team and experienced professional construction team composed of professional and technical personnel to ensure the introduction of international advanced design concepts, using the global standard technical specifications, construction commissioning perform a complete and strict project management specification. The company pursue the "dedication to customer service indoor clean air system, customer satisfaction is our aim," the operating principle, strive to win-win cooperation, in order to satisfy customer needs.
