Objectives: Energetic and exergetic analysis of the low-temperature heating system in a model library are conducted numerically in this research.
Methods: The method of numerical investigation and simulation are employed to compute the energetic and exergetic analysis of the low-temperature heating system in a model library. The use of C++ programming and Hourly Analysis Program software were done the simulation and optimization. The results of this investigation are presented in this article.
Findings: Simulation presents that the most of energy which is required for heating is capable to be declined using low-temperature heating system in a model library. It is shown that gas consumption decreases when lowtemperature radiators are applied and the value which is obtained is about 61,458,480 m3/yr. This means that the performance of the lowtemperature radiation is better than high-temperature radiator and it is about 57,150,000 m3/yr. The use of low-temperature radiators and high-temperature radiators are compared in this article. The radiator quality factor of the low-temperature radiators and hightemperature radiators are obtained 0.13 and 0.22, respectively. By using the low-temperature method, radiator quality factor is able to be declined 7% of the energy efficiency. Based on these cases, using the low-temperature system can be used in some regions in Iran. The economic investigation shows that the IRR is evaluated based on discount 30%, and interest rate 22% in 20 years.
Application and improvement: The declination of energy consumption in building is significant. Therefore, a method which can use to reduce energy consumption is low-temperature heating in winter.
Keywords: Low Temperature Heating, Low Temperature Radiator, Heating, Economic evaluation.
