Description
In 1993 the Department of Energy (DOE) released new energy standards that brought about new reciprocating compressor designs. The next increase in energy standards was due to come out in 1998. However, cutbacks in government spending has delayed this increase. It is estimated that the new standards will take effect sometime in 2000. When these new standards take effect, the next step in compressor design will need to be taken. Variable-speed technology is one way of reaching this next plateau.
By applying a brushless DC motor to existing compressor technology it is possible to reduce sound and vibration levels and increase overall cabinet (refrigerator/freezer) performance. A motor comparison and an analysis of piston rod stresses at high speeds and oil pumping capability at slow speeds are discussed in this paper.
