Design of Central Air Conditioning System for Hotel in Beijing

Abstract: This central air-conditioning system design for one hotel in Peking is to provide the staff and the customers with comfortable and peaceful environment. There are totally 8 floors in the hotel, which includes entertainment rooms and guest rooms. This design included: cooling-heating load calculation of air-conditioning; the choice and determination of air-conditioning system; the choice of cold and heat source;  the choice of fan coil type and fresh air handling unit type; the design of wind system; the design of water system; the design of insulating layer; the design of noise elimination and quakeproof, and etc. According to the related requests, this design is in view of the comfortable capability and environmental protection. The designed air-conditioning system uses fan coil system – central ventilation system, which contains a fresh air ventilator on each floor to convey fresh air. This design will provide a peaceful, comfortable, thorough and environmental-friendly air-conditioning system for the hotel.
