RE-Lab-Projects/hplib: heat pump library

hplib - heat pump library

Repository with code to

• build a database with relevant data from public Heatpump Keymark Datasets
• identify efficiency parameters from the database with a least-square regression model
• simulate heat pump efficiency (COP) as well as electrical (P_el) & thermal power (P_th) and massflow (m_dot) as time series.

For the simulation, it is possible to calculate outputs of a specific manufacturer + model or alternatively for one of 6 different generic heat pump types.

Documentation

If you're interested in how the database and parameters were calclulated, have a look into the Documentation HTML or Jupyter-Notebook. There you also find a simulation examples and a validation.

Usage

• Download or clone repository:
• Create the environment: "conda env create --name hplib --file requirements.txt"
• Create some code with import hplib and use the included functions load_database, get_parameters and simulate.

Heat pump models and Group IDs

The hplib_database.csv contains the following number of heat pump models, sorted by Group ID

Group 1, Outdoor Air / Water, Regulated (366 Models)
Group 2, Brine / Water, Regulated (54 Models)
Group 3, Water / Water, Regulated (0 Models)
Group 4, Outdoor Air / Water, On-Off (23 Models)
Group 5, Brine / Water, On-Off (53 Models)
Group 6, Water / Water, On-Off (10 Models)

Database

All resulting database CSV file are under CC-BY-4.0 license.

The following columns are available for every heat pump of this library

Input-Data

The European Heat Pump Association (EHPA) hosts a website with the results of laboratory measurements from the keymark certification process. For every heat pump model a pdf file can be downloaded from https://keymark.eu/en/products/heatpumps/certified-products.

This repository is based on all pdf files that were download for every manufacturer on 2021-03-12.
