Abstract: A compression device includes a first compressor and a second compressor mounted in parallel, each compressor including a leakproof enclosure including a low pressure portion containing a motor and an oil sump, an oil level equalization conduit putting into communication the oil sumps of the first and second compressors, and control means adapted for controlling the starting and the stopping of the first and second compressors. The first compressor includes first detection means coupled with the control means and adapted for detecting an oil level in the oil sump of the first compressor. The control means are adapted for controlling the stopping of the second compressor when the oil level detected by the first detection means falls below a first predetermined value.

Abstract: This compression device comprises first and second compressors mounted in parallel, a suction line intended to be connected to an outlet of an evaporator, first and second suction conduits arranged for putting the suction line respectively in communication with the admission orifices of the first and second compressors, and an oil level equalization conduit connecting the oil pans of the first and second compressors. The compression device further comprises an oil separator mounted on the suction line or on the second suction conduit, and an oil return conduit arranged for connecting an oil outflow orifice of the oil separator to the oil pan of the first compressor.
