Dear TRNSYS users! I am running a Type 927 water-water heat pump with a borehole field as source. The heat pump heats a storage tank which in turn supplies several secondary heating systems. Now I want to model 4 identical heat pumps and determine the number of heat pumps on depending on the return temperature from the storage tank to the heat pump. If the temperature is below a certain set point I want to
start another heat pump and if the temperature is too high I want to switch one off. I tried to write a short code in the w-interpreter but my problem is that the heat pump component can’t tell another component how many heat pumps that are already running. Therefore the option “start one more heat pump”
is not available. Is it possible to let another component store the input variable to Type 927 so it can be available in the next time step? Or do anyone have any idea on how to achieve what I want to do? Best regards Mattias Ericsson |
