The calculation method of the heating loss of piping network

the selection of the key parameters and the data source are introduced in detail in this paper. According to the annual meteorological data and the annual load prediction

combined with the actual situation of a project in Shanghai

the design condition and the annual heating loss are calculated

the results show that:the heating loss of cooling pipe network in design condition is about 0.2% of cooling capacity;the annual cooling loss accounted for about 0.8% of the cooling capacity;and the proportion of heating loss of the cooling pipe network is small

and much smaller than the heating loss of the heating pipe network.
