Applied Research Of Low Temperature Hot Water Radiation Floor Heating System

Low temperature hot water radiant floor heating is a heating system of using the building ground inside for heating. It regards the whole ground as a heat dissipation surface, saves fuel with advantages of low power consumption, high energy efficiency and thermal comfort in order to make the floor heating forms and range of applications expand. The system was first produced in the United States and Europe, Japan, Korea and other developed countries. The United States and Germany have formed a relatively complete radiant floor heating standards. The system started late in China, but its research results are equally impressive. As the result, low temperature hot water radiation floor heating technology as an energy-saving heating system has been widely promoted and used. However, there are some problems in the pipe, construction, operation and other aspects of chains in practical engineering application.In this essay, a detailed analysis is given on the problems in the comparison and selection of floor heating pipe performance, the problems of low temperature hot water floor radiation heating system and the analysis of the case about radiation floor heating system of household metering floor heating system. The thesis mainly contains the following contexts: (1)This paper introduces the test principle, the works, the function, the precision of the instrument and data Transmission System of the main instrument in the heat meter structure. It plays an important role in ensuring the measurement accuracy of the test, uniformity and timeliness of the data.(2) It regards Residential users of Metallurgical Design Institute, Shanxi Province as the trial, builds a test platform on this basis and monitors the system for a period up to the heating of a heating season, collects the supply and return water temperature, the return water temperature differences, instantaneous flow, thermal power, the total for the heat and other data to realize the data automatically recorded.(3)Household unit of measurement of floor heating systems floor hydraulic calculations, to verify the different programs, the gravity natural role of pressure to overcome the resistance of the pipeline imbalance, the elimination of vertical hydraulic imbalance. It analyzes the heating data of eight representative thermal users in Metallurgical Design Institute, Shanxi Province for ten typical days.
