Verification of PyDHN - a Python library for the thermo-hydraulic simulation of district heating networks - through the DESTEST

2023

Abstract

Due to the scarce availability of monitoring data and, when available, possible confidentiality issues, inter-model comparisons are a valuable way to verify the consistency of results in simulations of District Heating Networks (DHN).This paper presents the verification of PyDHN through the DESTEST, a benchmark test developed as part of IBPSA project 1, currently providing comparison with six other DHN models.We conducted two network exercises (CE0 and CE1) out of the four included or planned in the test and suitable for our tool. The results for the steady-state exercise (CE0) show an accuracy of 84.77%. To simulate the thermal transient exercise (CE1), a simple quasi-dynamic pipe model is developed as a custom component. As the results of only one alternative model,are currently available for CE1, we show a good agreement between the results of the two models on most indicators with an average absolute NRMSE of 17%.

Central heating

A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators.

District heating

District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation.

Python (programming language)

Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library.
