The building is located in Guangzhou, is a 15-story luxury hotel, the building area of 142806 square meters. A main foyer, reception, as customers, 2 to 4 for layers to restaurant in the hotel, 5 to 15 for a hotel room, each room comes with both toilet and wash basin features, sitting stool and shower. The air-conditioning design is mainly directed for the whole building.
Main methods of this design is according to the design plan, combined with the knowledge, access to data and specifications, according to actual condition choose different cold and heat source for heat and mass transfer, and the air conditioning mode, design conform to the requirements of the specification, safety, energy saving, reliable, durable, meet the building function of hvac system.Specific design content includes:
1. The air conditioning room cooling load in summer and winter heating load calculation;
2. The fan coil plus fresh air system design;
3. The wind system design;
4. The design of water system;
5. The choice of cold and heat source;
6. Refrigeration room and air conditioning equipment room arrangement;
7. Air conditioning pipeline and equipment noise reduction measures;
8. Draw all kinds of system main plane, section and system diagram.
The whole building, all adopted the new Canadian Wind fan coil air-conditioning systems. As a result of these air-conditioned rooms more, the corresponding area of smaller, separate rooms require adjustment, and the room temperature and humidity requirements do not strictly, have adopted the new Canadian Wind fan coil air-conditioning systems.
The new wind-based system, an independent supply of indoor and outdoor weather can change with the adjustment, which is the new wind to deal with indoor parameters, do not assume room load to ensure that indoor humidity and Xinfeng Liang requirements. This programme is improving the system of regulation and the flexibility of operation, and the fan-coil into the water supply can be appropriately raise the temperature, water mains condensation phenomenon can be improved.
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.
