Description
Block Controlled Reservoir (G) It represents an endless reservoir with variable pressure and temperature. Port A (gas) corresponds to the entrance to the tank. The P port receives the pressure setting signal in the tank. The T port receives a temperature setting signal in the tank.
The volume of gas inside the tank is considered infinite, so the gas flow through the port is assumed to be quasi-stationary.
The gas enters and exits the tank at a pressure set for the tank, but its temperature is determined by the direction of the gas flow. If the gas enters the tank, its temperature is determined by the previous gas network, then the tank acts as a heat sink. If the gas exits the tank, then its temperature is equal to the temperature of the tank, and the tank acts as a heat source.
