The main basis of this design are:“the civil building heating ventilation and air conditioning design standard (GB50736-2012)”,“the code for fire protection design of buildings (GB50016-2014)”,“public building energy efficiency design standard (GB50189-2015)”, etc.
Hangzhou Xiangyun Hotel is a restaurant,office, leisure, entertainment and accommodation for the integration of multi-functional commercial building, etc.Building a total of seven layers, one to five layers are 4 m high, six and seven layers of high of 3.5 m, total height 27 m.A total construction area of 12527.1 m2, including air conditioning area covers an area of 7842 m2.Air conditioning room types mainly include the reception hall, business center, bars, KTV rooms, restaurants, bowling room, office, room, and bath center, etc.Load calculation using hongye 8.0 software room in the building air-conditioning system load calculation, the total cooling load in summer a maximum of 981.6 kW, in time to 17:00, air conditioning cold area is 126.0 W/m2, total fresh air cooling load is 374.1 kW.Use time as a result of each function room, from the Angle of the meet customer comfort and energy saving, selects fan-coil unit plus fresh air system, each room can be independent control system of the open and closed.In the center of the reception hall, bar, billiards room large area such as the fresh air and fan coil units are independent of air supply mode of air supply;In the KTV rooms, dining rooms, office and guest room small area room USES air blended with fan coil air supply mode of air distribution.Consider to decorate a requirement, fan coil units chosen carrier horizontal dark outfit 42 series, fresh air unit selects the carrier condole DBFPX series.Fan coil units in and out of the water pipes are installed valves, in order to convenient after maintenance needs.Fresh air unit selection to meet the required amount of wind, cold, and residual pressure requirements.One to five layer on each floor are set with 2 fresh air units, six and seven layers each set 1.Suction FengKouChu with rainproof shutter, duct using soft connection, and install the fire damper.Half a ceiling of room available, such as guest room, use air supply side, side air supply outlet choose double shutter form;Other rooms adopt inverter air supply way, scattered inverter to choose square diffuser;Return air mouth in the form of single louvers, giving last time.Chilled water system USES two control, closed loop system, the layers of the pipe process arrangement, using the regulator to adjust balance.Chiller setting on the roof platform, choose joint carrier air conditioning co., LTD. (Shanghai) 30GX series 2 units, air-cooled screw water chillers models for 30GX182, 118 m3/h, 50 kPa pressure drop, cooling water in 12 ℃, under the condition of water 7 ℃.Choose Hunan Xiaoxiang system pump co., LTD production VGDW50-35 three type of frozen water pump, and a case, the flow of 35 m3/h, head of 26 m.Produced by Shanghai industrial co., LTD. The flag in the design of constant pressure type SC600 expansion tank, at the same time also have exhaust, filling water as well as the water volume expansion caused by temperature change and give room for action.The system is running the discharge of condensate by condensed water pipe concentration.In addition, I also for the insulation of air conditioning system, and shock absorption and so on has carried on the simple design.
