摘要： An apparatus controls a variable displacement compressor used in a refrigerant circuit. The compressor includes a drive shaft, which is rotated by an engine. When the drive shaft rotates, the compressor compresses refrigerant sent from the external refrigerant circuit and discharges the compressed refrigerant to an external refrigerant circuit. When the displacement of the compressor is minimized, the circulation of refrigerant in the refrigerant circuit is stopped. The apparatus has a control mechanism for varying the pressure in the crank chamber. A detector detects a physical quantity that reflects the heating status of the compressor. When the compressor displacement is minimized and the quantity detected by the detector indicates that the heating status of the compressor is deteriorating, a controller commands the control mechanism such that the displacement of the compressor is greater than the minimum displacement.

摘要： A method for controlling compressor discharge pressure in a compressor. The compressor comprising a compression module driven by a prime mover, the compression module having a discharge port through which a compressed fluid is discharged with a discharge pressure, and an inlet through which uncompressed fluid is flowed into the compression chamber, the flow of fluid through the inlet controlled by an inlet valve repositionable by an actuator driven by a motor. The method comprising the steps of running a discharge pressure control routine, comprising the steps of: calculating the difference between the actual discharge pressure and a predetermined setpoint discharge pressure; computing the required change in valve position to achieve the setpoint discharge pressure, the period of time the motor means must be energized to produce the change in valve position, and the direction the valve must be moved to produce the setpoint discharge pressure. The method including the additional steps of running an actuator position control routine, comprising the steps of: energizing the motor in the required direction for the computed period of time; and braking the motor by energizing the motor in a direction different than the required direction for a braking time interval.

摘要： A system includes a sensor and a controller for a refrigeration or HVAC system having a compressor. The sensor senses a temperature of the compressor during operation of the compressor. The controller is configured to determine a rate of change of the temperature relative to time and to perform one or more procedures to protect the compressor based on the rate of change of the temperature. The one or more procedures to protect the compressor include shutting down the compressor, throttling a pressure regulator valve of an evaporator associated with the compressor, adjusting an expansion valve associated with the evaporator, reducing speed of the compressor, and partially or wholly unloading the compressor.

摘要： Process for regulating a compressor with motor for a refrigerating system, where the temperature of the cooling site is regulated through an on-off motor mode if the temperature in the compressor exceeds an upper temperature threshold. In addition, the temperature of the cooling site is regulated through a continuous on mode of the motor as soon as the motor has cooled to a lower temperature threshold. The controller converts a variable corresponding to the cooling requirement of the cooling site into a switch signal for a valve, which results in clocked opening and closing of the valve, or uses a frequency converter, which controls the cooling liquid flow through the compressor by regulating the voltage and the frequency of the motor in that the frequency converter converts a variable corresponding to the cooling requirement of a cooling site into a voltage and a frequency for the motor.

摘要： Method and equipment to control operating temperature of an air compressor. A compressor element compresses air and oil and supplies it to an oil separator. In the separator, the air and oil are separated. Oil is led to a circulating pipe and returned to the compressor element. When necessary, at least some of the oil flowing in the oil circulating pipe is supplied to cooling, which is used for controlling operating temperature of the compressor such that it is as low as possible, but nevertheless so high that no condensation point is reached. The amount of oil to be supplied to cooling is controlled by a thermostatic valve based on a change in dimension of a controlling element such that dimensions of the controlling element are changed by an external command.

摘要： The variable displacement swash plate compressor includes a housing, a drive shaft, a swash plate, a piston, a bleed passage, a supply passage and a low-melting member. The housing has a cylinder bore, a suction chamber, a discharge chamber and a crank chamber. The swash plate is supported in the crank chamber by the drive shaft and inclination angle of the swash plate is adjustable. The piston is reciprocally movably received in the cylinder bore. The bleed passage is formed in the housing in communication with the crank chamber and the suction chamber. The supply passage is formed in the housing in communication with the discharge chamber and the crank chamber. The low-melting member is disposed in the bleed passage so as to restrict fluid flow therethrough and has a lower melting point than the housing. When the low-melting member is melted, an opening of the bleed passage is increased.

摘要： A method for optimizing the operating efficiency of a compressor having a compression module for compressing a fluid, the compression module including an inlet for receiving the fluid and an outlet for discharging compressed fluid, the compressor including a prime mover for driving the compression module and a rotatable fan for drawing ambient air into the compressor. The compressor includes a first temperature sensor for sensing the temperature of compressed fluid discharged from the compression module, a second temperature sensor for sensing the temperature of a coolant circulating through the prime mover, a third temperature sensor for sensing the temperature of the fluid entering the compression module, and a fourth temperature sensor for sensing the temperature of a lubricant mixed with the fluid as the fluid is compressed in the compression module. The compressor includes an electronic control module (ECM) electrically connected to the four temperature sensors for receiving signals therefrom. The ECM includes a non-volatile memory containing empirical data relating to optimal operating set points of the compressor and a logic routine for controlling the rotational speed of the fan and the volume of the lubricant mixed with the fluid so as to optimize the efficiency of the compressor. The method includes the steps of executing a temperature sensing subroutine whereby the first, second, third and fourth temperature sensors collect temperature data and relay the temperature data to the ECM, executing a fan speed subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the rotational speed of the fan, and executing a lubricant volume control subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the volume of the lubricant mixed with the fluid in the compression module.
