Efficiency of the idealized cycles of vapor compressor refrigerating machines with adiabatic or isothermal compression of refrigerantwas investigated. To these cycles concern cycles with adiabatic compression of steam without regeneration (S-cycle) and with limiting regeneration (SR-cycle), and also with isothermal compression and limiting regeneration (T-cycle). Three characteristics of cycles are compared: refrigerating coefficient of performance e, specific-volume cooling capacity qv and total loss of exergy de. Calculations shoved that most effective is T-cycle, but value of qv for him and SR-cycle coincides.
