Abstract
An air conditioning system includes a first compressor and a second compressor arranged in parallel with the first compressor. The first compressor is a first type of compressor and the second compressor is a second type of compressor different from the first type of compressor. A valve is arranged upstream from both the first compressor and the second compressor relative to a flow of a fluid. The valve is operable to selectively supply the fluid to the first compressor, the second compressor, or both the first compressor and the second compressor.
Claims20
An air conditioning system comprising:
- a first compressor;
- a second compressor arranged in parallel with the first compressor, wherein the first compressor has a first configuration and the second compressor has a second configuration different from the first configuration;
- and
- a valve arranged upstream from both the first compressor and the second compressor relative to a flow of a fluid, the valve being operable to selectively supply the fluid to the first compressor, the second compressor, or both the first compressor and the second compressor.
An air conditioning system comprising:
- a first compressor, wherein the first compressor is a high side compressor;
- a second compressor arranged in parallel with the first compressor, wherein the second compressor is a low side compressor;
- and
- a valve arranged upstream from both the first compressor and the second compressor relative to a flow of a fluid, the valve being operable to selectively supply the fluid to the first compressor, the second compressor, or both the first compressor and the second compressor.
A method of modulating a flow of fluid to a plurality of compressors in an air conditioning system comprising:
- determining a loading of the air conditioning system;
- adjusting a position of a valve to deliver a fluid to at least one of the plurality of compressors in response to the loading of the air conditioning system.
