Piezoelectric compressor and piezoelectric refrigerator using the same

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a compressor and a vapor compression type piezoelectric refrigerator using the same, and more particularly, to a piezoelectric compressor and a piezoelectric refrigerator using the piezoelectric element. The piezoelectric compressor includes a sealed case having a predetermined internal space, a piezoelectric element provided inside the case, and at least two valves installed in the case and allowing the refrigerant to flow in and out of the case. The piezoelectric refrigerator includes a piezoelectric compressor A condenser, an expansion valve, an evaporator, and the like. The piezoelectric compressor thus constructed and the piezoelectric refrigerator using the same can be firstly energy efficient, have no second noise, have a long life span, fourth can use various refrigerants, fifthly do not cause environmental pollution, and can be miniaturized sixth.
