Greetings,

This question might be somewhat elementary, but anyways here it goes:

If we look at COP(refrigeration) it tells us the ratio of Work in compared to energy drawn from cold side. However I wonder what is the energy drawn from cold side vs. the total thermal energy of system. Since the work put in to the refrigeration cycle is converted to mechanical work and heat and others. Therefore not all work put in to the cycle is converted to heat.

So, what are typical QL(energy drawn from cold side) vs. the total heat energy produced by system, neglecting all the mechanical loss, electrical loss, etc.


Thanks in advance,
