Study on the Thermal Performance of Plate Heat Exchanger of Central Heating System

Take heat exchangers in some centralized heating system of Beijing as the research objects,through the pipe network system of hot water supply and return water temperature and gas consumption analysis of data,the error transfer theory,calculated the central heating system in the actual thermal performance of plate heat exchanger. According to the plate heat exchanger and puts forward relevant measures should be taken to improve the operation and maintenance of the thermal performance,such as dredging the pipeline of heat exchanger,enhancing heat exchanger heat insulation,reducing the heat loss of heat exchanger and the external environment etc.
