i wanted to design a system that get heat by R134a from a room and cool it down then take it to heat exchanger and transfer the heat to PG. afterwards, from stored heat in PG i wanted to design heat pump. but i can not debug my system.

Your model reminds me of this example:

Do you think this will help?

If you'd like to learn more about modeling refrigeration systems (since you mentioned R134a), check out this workflow example:
