By loss due to temperature, what do you mean? One can calculate different energy values by assuming different temperature profiles. It seems to me that regarding a difference in energy as a loss due to temperature requires choosing one temperature profile as a reference. |

If you are using ModelChain, run once with the ambient air temperature and save the total energy (mc.results.ac.sum()) Then create a copy of the weather file, insert weather_copy['temp_cell'] = 25. and remove ambient temperature weather_copy.drop('temp_air') Then run ModelChain again and you should get a different cell temperature and AC energy. I haven't coded this. |
