Abstract
A hermetic compressor for positive displacement is disclosed whose airtight housing is specially altered so that its natural frequencies of vibration are distributed at frequencies above 4200 Hz and whose “capacitance density” is greater than 160 W/L.
Claims6
Hermetic compressor for positive displacement, of the type that comprises:
- at least one airtight housing defined by the joining of at least one body and at least one cap;
- at least one compression mechanism defined by at least one compression cylinder and a movable piston;
- at least one electric motor controlled by at least one electronic control system;
- said compression mechanism and said electric motor being functionally cooperative with each other;
- said compression mechanism and said electric motor being housed within said airtight housing;
- said hermetic compressor for positive displacement being especially characterized by the fact that:
- said airtight housing comprises the first natural frequency of vibration greater than 4200 Hz;
- and
- the “capacitance density” is greater than 160 W/L.
