Air to Air Heat Pump

This is a template for a residential Heat Pump system experiment with R-32 as refrigerant by default (User can also change the refrigerant). The system follows a vapor compression cycle with air as secondary fluid in condenser and evaporator. The superheating at the evaporator is regulated by a thermostatic expansion valve. The system is initialized with a given specific charge. The Air side and compressor conditions can be given as a boundary conditions. This template can be used for specific purpose like standalone heat pump systems. This model is extended from HeatPumpCircuitBase
