5. C.O.P. c.o.p.cooling c.o.p.heating c.o.p.heating = 1 + c.o.p.cooling
Factor that designates the useful cooling capacity per unit of energy supplied by the compressor
c.o.p.heating
Heating capacity at the condenser per unit of energy supplied by the compressor
c.o.p.heating = 1 + c.o.p.cooling

6. Entropy entropy, symbolized by S
state function of a thermodynamic system defined by the differential quantity dS = dQ / T,
dQ is the amount of heat absorbed in a reversible process in which the system goes from one state to another
T is the absolute temperature
kJ / kg K
