The room shown in Figure 1 has a heater with heat flow rate
input of q0. The thermal capacitances of the heater and the room
air are C1 and C2, respectively. The thermal resistances of the
heater–air interface and the room wall–ambient air interface are R1
and R2, respectively. The temperatures of the heater and the room
air are T1 and T2, respectively. The temperature outside the room
is T0, which is assumed to be constant.
