Large solar heating system model based on transient system (TRNSYS) and modeling method

Abstract

The invention provides a large solar heating system model based on a transient system (TRNSYS). The large solar heating system model based on the TRNSYS comprises a meteorological parameter input part used for setting meteorological parameters, a water use load part used for setting the water use amount of a solar heating system, a solar thermal collector part used for setting the type and total area of a solar thermal collector, a water tank part used for setting the volume of stored water, a circulation water pump part used for setting a water pump and the circulation water flow of the large solar heating system, a system operation control part used for controlling starting and stopping of the water pump and a simulation result output part used for outputting the simulation result. The invention further provides a modeling method of the large solar heating system model. The TRNSYS software is used for designing the large solar heating system model. The simulation result of the model is well matched with the actual operation conditions of the system, the specific operation conditions of the system are fully displayed, and powerful bases are provided for design, optimization and evaluation of the large solar heating system.

Description

technical field [0001] The invention relates to the technical field of system modeling and simulation of large-scale solar heat collection arrays, in particular to a TRNSYS-based system model and a modeling and simulation method for large-scale solar heat collection arrays. Background technique [0002] With the continuous development of the solar heat utilization industry, large-scale solar heat collection systems have been widely used in industries, agriculture, and commerce. Compared with small-scale solar thermal collection systems, large-scale solar thermal collection systems have many problems in system construction and operation monitoring, which have caused great problems for system design and performance evaluation. On the other hand, although the large-scale solar heat collection system is developing rapidly, the number of its construction is still very different from that of the small-scale system, which makes the opportunities for experimental analysis of the sys...
