WebDec 6, 2010 · The simple system in Figure 1 shows the application of the Second Law of Thermodynamics. The compressor (A) adds energy to the refrigerant, and it becomes hot, just the way a hand operated tire pump does. Since the compressed refrigerant is hotter than the air blowing across the condenser (B), the heat will flow to the cooler air. WebRefrigeration Cycle It is a well known fact that heat flows in the direction of decreasing temperature, i.e., from a high temperature region to a low temperature region. But the reverse process (i.e. heat transfer from low to high temperature) cannot occur by itself (Claussius Definition of Second Law).
