Title The Heating Ventilation Air Conditioning Engineering Design
of An International Business Hotel In Guangzhou
Abstract
The engineering is a design of the heating ventilation air conditioning of an international business hotel in Guangzhou. The business hotel is a four-storey above-ground building. The ground floor is designed for equipment and catering, the first floor for leisure, entertainment and catering, the second floor for conference, business, catering and entertainment and the third floor for fitness and guest rooms.
This engineering makes the load calculation for each room with air-conditioner in the entire building, analyses the load structure of rooms with various functions, and chooses the cold and heat source system according to the load. The chilled water system is designed as a closed-loop direct return system, while the cooling water system as a cooling circulatory system. Large local wind system such as restaurant is designed as an all-air system, while small interspace wind system such as guest rooms as a fan coil and dedicated outdoor air system. The air distribution in the typical air-conditioned room is also calculated. Besides, common antechamber and staircase adopts the positive pressure ventilation system.
Keywords heating ventilation air conditioning air conditioning ventilation system air conditioning water system air distribution
