condenser core temperature and the ambient available to reject the heat in particular by employing a controller to continuously modulate the speed of the compressor the compressor speed can be reduced resulting in less mass flow of refrigerant to the evaporator so that the evaporator and condenser may be held at desired core temperatures and pressures in so doing the extremely low evaporator temperatures that are a natural side effect of cycling systems are able to be substantially eliminated thereby shrinking the size of the refrigeration cycle and minimizing cycling losses to provide a higher compressor eer and system coefficient of performance cop in exemplary configurations such a controller may include but is not limited to a proportional p controller a proportional integral pi controller a proportional integral derivative pid controller a fuzzy logic based controller a neural network or a look up table based controller with reference to fig4 there is illustrated a graphical representation 400 demonstrating the energy saving potential between a time averaged baseline cycling control 402 and a pid modulated cycle 404 in accordance with present technology as can be seen with relation to saturation phase line 406 the average pid modulated cycle 404 transitions from points 1 2 3 4 while baseline cycle 402 transitions from points a b c d in accordance with present technology however this modulated cycle 404 removes the same amount of latent heat over time as the baseline cycle 402 but with fewer start losses and with more stable resulting temperatures from this it will be appreciated that the latent heat extracted by evaporator u03b4h a b u03b4h 1.
