This building including shopping malls, restaurants, entertainment, guest room

21、s, conference rooms, offices, a multifunctional building. Area of 9,997 , building height of 43.1M, building layers of a total of ten stories. First floor mainly for parking and air conditioning computer room located in the basement. Second floor mainly for shops and restaurants, is four to six main

22、 office area, is seven to ten main rooms. Under the floor, the functional requirements, the building needs to provide heat load in winter and summer with cooling load. To long-term interest as a starting point to achieve technology is a reliable, economical, energy-saving environmental protection, e

23、asy management, functional adjustment flexibility and use of safe and reliable. After the feasibility of various options and water systems, design of this fan-coil dedicated outdoor air systems; water system uses a pump, dual-control system: to meet the demand for the entire building, energy saving

24、in the process and in order to run, the design heat source using air-source heat pump module units. Calculated based on the summer air conditioning load Select units, equipment, fresh air handling units, air outlet at the end, finally, to equipment and piping for air conditioning systems take measur
