摘要： A controlled surface having a direct contact with a flow of cold air circulating within a climate-controlled space is provided. A thermoelectric device is associated with the controlled surface and has a hot junction positioned upstream in the path of the air stream moving over the controlled surface and a cold junction positioned downstream in the path of the air stream. This arrangement provides defogging, defrosting or condensate evaporation for the controlled surface, while the temperature in the climate-controlled space is not appreciably altered, and at least some amount of moisture is removed from the air stream by the thermoelectric device.

摘要： A refrigerant system is provided with a pulse width modulation suction valve and a second valve on a line that bypasses the pulse width modulation suction valve. This second valve has a variable opening. In this manner, the pressure within the compressor shell is maintained at the lowest possible level regardless of the system operating conditions, when the pulse width modulation suction valve is cycled to a closed position. Further, the second valve can continue providing capacity control, should the pulse width modulation suction valve fail.

摘要： A multi-rotor screw compressor includes a housing, a sun rotor, and first and second planet rotors. The first planet rotor intermeshes with the sun rotor to define a first compression pair. The second planet rotor intermeshes with the sun rotor to define a second compression pair. The first and second compression pairs are rotatably mounted in the housing. The housing includes a first port, a portion of which is in communication with the first compression pair, and a second port, a portion of which is in communication with the second compression pair. The portions of the first and second ports which communicate with the first and second compression pairs have a different geometry for offsetting pulsations in a working fluid flowing through the ports.

摘要： A refrigerant system is provided that includes a compressor, a motor for driving the compressor, a refrigerant system component, and a controller. The refrigerant system component can operate in a pulse width modulated mode having a loaded phase and an unloaded phase. The compressor motor is loaded in the loaded phase but unloaded in the unloaded phase. The controller applies a first voltage to the compressor motor in the loaded phase and a second voltage to the compressor motor in the unloaded phase. Here, the second voltage is less than the first voltage.
