First, the project only consider the summer air-conditioning design, set up two screw chillers in the basement refrigerator room, each cooling capacity 440kW, power 91kw, chilled water flow 75.6m3 / h, cooling water flow: 90m3 / h. York design company selected products (unit DDC interface). Construction owners choose Daikin unit for the single screw machine. Another due to a control room and related supporting requirements 24 hours a day, another set of small air-cooled unit, the cooling capacity of 51KW, the unit placed on the ground floor for the control room and related supporting housing Provide 8 hours of work outside the cold. Chilled water circulating pump with a prepared, flow 93.5m3 / h, power 11kw, head 28mH2O. Cooling water circulating pump with a prepared, the product model to determine the professional water supply and drainage. Two circular cooling towers are installed on the roof. Each treatment water volume is 105m3 / h. 2. The first floor of the air-conditioning air system adopts a low-speed variable air volume return air system. In different seasons, the fresh air volume can be controlled according to the enthalpy difference of indoor and outdoor air. The other side of the conference room on both sides of the wall to set the low-noise axial fan, excluding hot air above the meeting room. Basement management room, ground floor control room and related supporting rooms, offices, bedrooms, small meeting rooms and other rooms with fresh air plus fan coil air conditioning system. Ceiling-mounted fresh air units set at all levels, the fresh air is treated until the enthalpy state of the air supply, indoor air conditioning load borne by the fan coil. Three, air-conditioning water system Air conditioning water system is a dual-control system for a variable pump variable flow: through the supply and return pipes between the pressure-setting bypass valve and the end device to set electric two-way valve to achieve quantitative cold side, load side variable flow. Chilled water A total of A, B two stand pipe, led by the shaft to the various layers of fan coil or air handler, chilled water using two control system. Cold water temperature is 7 ℃ / 12 ℃, by the high expansion tank constant pressure replenishment. Fourth, the mechanical ventilation system Each bedroom bathroom set exhaust fan (installed inside the ceiling), through the shaft row to the outdoor, public toilets set exhaust fan will be dirty air discharged outdoors. Equipment room, warehouse, garage set mechanical exhaust, naturally into the wind. 7 air-conditioning controlled air-conditioning using DDC control system, designed and installed by a professional self-control company. Water system is set for the backwater differential pressure control, cold flow control and unit number and equipment operation control. Fifth, the design experience Because the design of the construction drawings of the open office is not parted, so only reserve the total cooling capacity and determine the layers of new fan air volume, only in the decoration phase according to the decoration requirements and meet the cooling capacity premise The layout of the fan coil, water pipes, fresh air duct, tuyere and so on. The type of outlet is set as a slit outlet or a square diffuser according to the decoration needs. Therefore, if the decoration involved early, you can avoid a large number of changes to the construction drawings and decoration with less than satisfactory results appear. In addition to controlling the wind speed of the wind pipe, the wind pipe is also equipped with a composite duct. In the air-conditioned room, the unit is muffled and the low noise cabinet type air-conditioning unit is selected. Plenum silencer are used.
