Abstract:
본 발명의 실시예에 따르면, 흡입기는 원형의 하우징 내부에 환형(環形)으로 형성된 유로와, 상기 하우징의 일측에 설치되어 상기 유로로 유체 유입을 안내하는 유입부와, 상기 하우징의 타측에 설치되며 상기 유입부로 유입되어 상기 유로를 통과한 유체의 토출을 안내하는 토출부와, 상기 유로 상에 배치되어 상기 유로를 따라 회전하며 상기 유입부를 통해 유입된 유체를 압축시키는 피스톤, 그리고 상기 유입부와 상기 토출부 사이의 상기 유로 상에 설치되고, 복수의 개폐부재 및 상기 복수의 개폐부재와 상기 유로 사이에 설치되어 상기 복수의 개폐부재를 각각 지지하는 탄성부재를 포함하여 상기 피스톤의 가압에 따라 상기 유로를 개폐하는 개폐부를 포함하며, 상기 복수의 개폐부재는 상기 피스톤에 의한 가압이 해제되면, 상기 유로를 폐쇄하는 방향으로 상기 복수의 개폐부재의 외주면을 가압하는 유체의 가압력과, 상기 탄성부재의 탄성력에 의해 상기 유로를 폐쇄하는 것을 특징으로 한다.
Abstract:
The present invention refers to a system and a method of remotely connecting and disconnecting an auxiliary power supply (19) of the frequency inverter for variable capacity compressors employed in cooling systems, wherein the inverter comprises a circuit breaker (10) which acts such that when it receives an external signal to activate the auxiliary power supply (30) indicating that the auxiliary supply (19) should be connected, the circuit breaker (10) enables the running of the auxiliary power supply (19), which activates the running of the inverter, and the inverter begins sending, continually, the internal maintenance signal to activate the auxiliary supply (40) to the circuit breaker (10) indicating that the auxiliary supply should be kept running, making the circuit breaker maintain the auxiliary power supply (19) enabled, and when the circuit breaker (10) receives an external deactivation signal from the auxiliary supply (30) indicating that the auxiliary supply should be disconnected, the inverter stops sending the signal to maintain the auxiliary supply activated (40) to the circuit breaker (10), and the circuit breaker (10) disables the auxiliary power supply (19), deactivating the running of the inverter.
Abstract:
A compressor electrical component enclosure may include a base and a lid. The base may include first and second opposing surfaces and a magnet. The magnet may be coupled to the second surface and may secure the base to a compressor shell. The lid may engage the base and cooperate with the base to define an electrical component housing.
Abstract:
Method for controlling a device (1) that comprises at least a compressor installation (2) and/or drying device on the one part, and a heat recovery system (3) on the other part, whereby the heat recovery system (3) absorbs heat from the compressor installation (2), and whereby the composite device (1) further comprises a controller (5) and means (6) for determining one or more system parameters, characterised in that the controller (5) controls both the compressor installation (2) and/or the drying device and the heat recovery system (3) on the basis of the aforementioned system parameters, such that the overall efficiency of the device is optimised.
Abstract:
A system includes a compressor having a shell housing a compression mechanism driven by an electric motor in an on state and not driven by the electric motor in an off state. The system also includes a variable frequency drive that drives the electric motor in the on state by varying a frequency of a voltage delivered to the electric motor and that supplies electric current to a stator of the electric motor in the off state to heat the compressor.
Abstract:
The invention provides control apparatus for use with a fluid displacement device, for example a compressor, the control apparatus comprising means (24) to detect the temperature of fluid being displaced by the device and means (11) to control the device independence upon the sensor temperature. Preferably there is also means (22) to sense the pressure of the fluid being displaced by the device, a combination of temperature signals and pressure signals being utilised to control the device. The invention enables very sophisticated monitoring and control to be carried out, for example utilising pre-selected temperature and pressure bands.
