Description

The experiment P2.6.2.3 determines the efficiency

of the hot-air engine as a refrigerating machine. Here, the hot-air engine with closed cylinder head is driven using an electric motor and Q₁ is determined as the electrical heating energy required to maintain the cylinder head at the ambient temperature
