6 Air conditioning water system
As the building's air conditioning system using water-pressure gas tank closure expansion tank means constant pressure. Taking into account the simple design of the pipe line system, the design of water systems in a dual-tube. Rooms vary for the horizontal part of program, namely for, the backwater stem the flow of the opposite direction, each Yi Huanlu ranging from the length of the pipeline, without the return by the way, tubes shorter length, the pipeline simple vertical for the same Program, that is, that is, for, backwater stem the flow in the direction of the same, after each Yi Huanlu the same length of pipe, use of the way so that water distribution, regulation of convenient.
Conversion to take the season points, catchment on a valve switch. Air-conditioning units and fan coil back on the water pipes for electric two-valve, air-conditioning load in accordance with changes in regulation of water through the coil, at the catchment-based electric pressure difference between the bypass valve to maintain pressure on the balance system.
7 Bathroom ventilation design
The project room toilet located mechanical ventilation devices, set exhausting-fan, the ventilation of toilet by 20-30 m3 / h. Windowless bathroom set up exhaust-opening, exhaust duct from the same access to, from exhaust to the outdoors-row. And around the external walls and windows of a bathroom, directly into the outdoors. Toilet maintain negative pressure to prevent the leakage of odors and toilet optional and exhausting-fan check valve.
