Abstract
Accuracy of temperature control is improved by a unit modulating the control of refrigeration adjustment devices by means of sets of brief impulses. The duration of each impulse, and that for which modulation is applied can be adjustable, and initiation of impulses can be caused by operation of the device supplying refrigeration energy. The modulation can be electrical, electro-mechanical or electronic, controlling refrigerating fluid valves, to adjust existing fluid pulses. The unit may be adapted for a proportional temperature regulator.
