Brief Description of Core Concepts:

Heat Engine 🔥

• Based on Kelvin-Planck’s Statement, a heat engine converts heat into work.
• Efficiency is the ratio of work done to heat energy supplied, with net work done being crucial.
• The efficiency formula: Efficiency = (W) / (Q1 – Q2), which simplifies to Efficiency = (T1 – T2) / T1 or 1 – (T2 / T1).

Refrigerator ❄️

• Based on Clausius Statement, a refrigerator’s coefficient of performance (COP) is the ratio of heat absorbed to work done on the system.
• COP formula: COP = Q2 / (Q1 – Q2), which simplifies to COP = T2 / (T1 – T2). Note that COP is the reverse of efficiency.

Heat Pump 🌡️

• Similar to a refrigerator, a heat pump operates on Clausius Statement, with COP being the key metric.
• COP formula: COP = Q1 / (Q1 – Q2), which simplifies to COP = T1 / (T1 – T2). The COP of a heat pump is simply the COP of a refrigerator plus one.
