Title The design of HVAC engineering in a communication commanding and dispatching center in ShangHai
Abstract This paper introduces the design of HVAC(heating,ventilating and air conditioning) engineering in a communication commanding and dispatching center in ShangHai。With an actual project,this paper presents the calculation and analysis of cooling and heating load, the design of cold and heat source,ventilation,thermostatic and humidistat air conditioning and smoke control。The cold and heat source with chilled water unit and hot water boiler which share a set of pipeline system, switches the line through the valve in winter or summer。 The office building is mainly used fan coil and fresh air system。However,several space adopts all-air system。Due to large heat dissipation capacity,the equipments in communication room need cooling throughout the years。Therefore the refrigeration system is independent。The machine room supplies air with moving belt ground plates and returns air at the top。
Through the engineering design, we synthetically apply the basic theory, professional knowledge and fundamental skills。Meanwhile,the ability to solve the problem, design,calculate,engineering draw and aid design with computer has been greatly improved。
Keywords cold and heat source, ventilation, thermostatic and humidistat air conditioning, smoke control
