Abstract: A system may receive, identify, and/or extract one or more pieces of information (e.g., categories of knowledge) from an input (e.g., a knowledge source, as described herein). The categories of knowledge may include one or more phrase and/or multi-word phrase, which may be referred to as individual pieces of knowledge (e.g., knowledge entities). The system may identify one or more relationships between the categories of knowledge and/or the individual pieces of knowledge. For example, the relationships may be inter and/or intra-categorical relationships. The relationships may be organized to form a hierarchical relationship driven knowledge engine. The knowledge engine may organize the knowledge entities by entity (e.g., operator, company, job posting) and/or contextualize the knowledge entities by domain (e.g., profession, employer, etc.) by, for example, creating one or more knowledge profiles. The knowledge engine may then use these knowledge profile to dynamically respond to informational requests.

Abstract: A vapor compression system includes a fluid circuit circulating a refrigerant in a closed loop. The fluid circuit has operably disposed therein, in serial order, a variable speed compressor, a first heat exchanger, an expansion device and a second heat exchanger. A first blower device is associated with the first heat exchanger. A speed of the first blower device is dependent upon a speed of the compressor. A second blower device is associated with the second heat exchanger. A speed of the second blower device is dependent upon the speed of the compressor.
