A thermal management system, a method of controlling the same, a compressor included in the same in which the thermal management system and the method of controlling the thermal management system determine whether the current state is a low-refrigerant state in which a refrigerant amount is smaller than a reference refrigerant amount on the basis of a degree of superheat or a degree of supercooling detected from a pressure and temperature of a refrigerant when a battery thermal management mode is operated and operations of cooling and heating a vehicle interior do not operate. The compressor is included in the thermal management system and configured as an electric compressor configured to be controlled by the control method. Therefore, it is possible to easily recognize whether the current state is the low-refrigerant state in which the refrigerant amount is smaller than the reference refrigerant amount.

Thermal management system, control method therefor, and compressor included therein

A compressor that includes a casing, a compression mechanism provided inside the casing to compress a refrigerant, a rotary shaft transmitting a rotational force to the compression mechanism from a drive source provided outside the casing, a clutch connecting the drive source and the rotary shaft by a magnetic force generated when electric power is applied to the clutch and disconnecting the drive source and the rotary shaft by losing the magnetic force when the electric power applied thereto is cut off, and a rotation measurement means for receiving the magnetic force from the clutch to measure a change in magnetic flux according to the rotation of the rotary shaft and measure a rotational speed of the rotary shaft. Thus, it is possible to measure the rotational speed of the rotary shaft without including a permanent magnet.

Compressor

A compressor having a front housing in which a crank chamber is formed. A cylinder block is coupled to an opposite surface facing the front housing and includes reciprocating pistons in a plurality of cylinder bores. A rear housing is coupled to an opposite surface facing the cylinder block, the rear housing includes a suction chamber and a discharge chamber formed therein. A rotating shaftis inserted via centers of the front housing and the cylinder block, the shaft inserted into a swash plate. A diameter maintenance part is configured to constantly maintain a diameter based on an axis direction of the piston. A sensor part is configured to sense a speed and a stroke of the piston in accordance with a change in position of a position determination part positioned on one side of the diameter maintenance part.

A variable displacement reciprocating piston unit includes a sensor probe, a target, a piston having a top dead center position and a bottom dead center position, and a signal processing unit. The sensor probe, the target, and the piston are located in relation to each other so that the target is moved from being absent from the sensor probe to being present at the sensor probe when the piston travels towards the top dead center position, and the target is moved from being present at the sensor probe to being absent from the sensor probe when the piston travels towards the bottom dead center position. The signal processing unit generates a signal indicating a stroke speed and a stroke length of the piston from a signal from the sensor probe indicating a presence and/or an absence of the target as the target moves relative to the sensor probe.

Disclosed herein is a vane rotary compressor in which a fluid such as a refrigerant is compressed while a volume of a compression chamber is reduced during rotation of a rotor. There is provided a vane rotary compressor capable of preventing a delay of rotation operation of a vane by respectively forming oil films on both sides of a hinge portion of the vane in a rotation direction thereof and smoothly sliding the hinge portion.

The present invention relates to a vane rotary compressor wherein the volume of a compression room is reduced and a fluid is compressed when a rotor rotates. According to one embodiment of the present invention, the present invention provides the vane rotary compressor for maximizing the rotational moment of a vane by extending a weight part at a front end part of the curved blade type vane so as to remove the hitting noise due to the delay of the rotational operation of the vane when the rotor is rotated, and increasing the performance by reducing the internal leak.

Vane rotary compressor

The present invention relates to a vane rotary compressor in which, while a rotor is rotating, the volume of a compressing chamber is reduced and a fluid such as a refrigerant is compressed. The vane rotary compressor according to one embodiment of the present invention is provided with the compressing chamber, the inner circumferential surface of which is formed in the shape of an involute curve, wherein the rotor is hinge-coupled with a plurality of cantilever vanes such that compression efficiency is high and noise is prevented from occurring during the operation of the compressor.
