Abstract

In systems comprising at least two compressors, the present invention provides an adequately sized vessel or tank in either or both the suction line or the discharge line of multiple compressors, in such a fashion that if the conditions of the first compressor change, it does not have an immediate effect on the other compressors, the vessel acting as a means of dampening the change.

Claims (12)

1. A multiple compressor system, comprising:
at least a first and a second compressors in parallel between a low-pressure side and a high-pressure side;
at least one inertia vessel connected to one of suction lines and discharge lines of said at least first and second compressors;
wherein the at least one inertia vessel acts as a means of dampening changes of operation condition of the at least first and second compressors.
2. The multiple compressor system according to claim 1, wherein said at least one inertia vessel comprises a low pressure tank connected to the suction lines and a high pressure tank connected to the discharge lines of the at least first and second compressors.
3. The multiple compressor system according to claim 1, wherein each of said at least first and second compressors is connected to a low-pressure tank and to a high-pressure tank.
4. The multiple compressor system according to claim 1, wherein said at least first and second compressors are selected among hermetic and semi-hermetic compressors, said at least one inertia vessel comprising a housing of the first compressor and a housing of the second compressor.
5. The multiple compressor system according to claim 1, wherein said at least first and second compressors are contained in a common housing, said at least one inertia vessel being formed by said common housing.
6. The multiple compressor system according to claim 1, wherein said at least one inertia vessel comprises a modular low-pressure tank and a modular high-pressure tank.
7. A method for controlling a compressor system including at least two compressors arranged in parallel between a low pressure side and a high pressure side, comprising the step of connecting at least one inertia vessel to at least one of: a suction line and: a discharge line of at least one of the at least two compressors.
8. The method according to claim 7, comprising connecting a common low-pressure tank connected to the suction lines of the at least two compressors and a common high-pressure tank connected to the discharge lines of the at least two compressors.
9. The method according to claim 7, comprising connecting each one of the at least two compressors to a low-pressure tank and to a high-pressure tank.
10. The method according to claim 7, the at least two compressors being selected among hermetic and semi-hermetic compressors, the compressors each having a housing, said method comprising connecting each housing of to the low pressure side and to high pressure side.
11. The method according to claim 7, the at least two compressors being contained in a common housing, said method comprising connecting the common housing to the low-pressure side and to the high-pressure side.
12. The method according to claim 7, comprising connecting a modular low-pressure tank to the low-pressure side and a modular high-pressure tank to the high-pressure side.
