摘要： Provided is a turbo compressor for compressing a gas such as air and supplying the compressed gas to outside, the turbo compressor including a compression unit including a compression gas inlet for sucking the gas, an impeller for compressing the gas sucked through the compression gas inlet, a compression gas outlet for discharging the gas compressed by the impeller, and a compression gas channel connected from the compression gas inlet to the compression gas outlet, a motor including a rotary shaft having a front end coupled to the impeller, to rotate the impeller, a housing having a motor accommodation space to accommodate the motor, and a cooling gas channel passing through the motor accommodation space and enabling circulation of a cooling gas contained therein, wherein the compression gas channel is spatially separate from the cooling gas channel and thus the gas in the compression gas channel does not permeate into the cooling gas channel.
According to the present invention, the motor may be efficiently cooled without pressure loss of the compression unit.

摘要： First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

摘要： A throttle valve for a centrifugal compressor includes a body having a central passage and one or more diverter flow paths. The central passage is formed by an inner surface of the body, each diverter flow path has an inlet and an outlet, and the one or more diverter flow paths are configured to induce a swirl within a fluid flow through the central passage while a portion of the fluid flow passes through the one or more diverter flow paths. The throttle valve also includes at least one blade disposed within the central passage. The at least one blade is configured to direct the portion of the fluid flow to the inlets of the one or more diverter flow paths while the at least one blade is in a partially open position.
