摘要： A claw pump includes: a housing which forms a pump chamber; two rotating shafts which are disposed parallel to each other inside the housing; a pair of rotors which are respectively fixed to the two rotating shafts inside the housing, each of the rotors being provided with two or more hook-shaped claws, the claws meshing with each other in a non-contact state; a rotary drive device which drives the pair of rotors to rotate; and a suction port and discharge ports which are formed in a partition wall of the housing. The discharge ports are respectively formed in side plates which form both axial end faces of the rotating shafts of the housing and are constituted by a first discharge port and a second discharge port which are formed at positions that communicate with a compression pocket formed by one set of the claws. The claw pump includes an opening/closing mechanism of the first discharge port and the second discharge port. The opening/closing mechanism discharges gas in the compression pocket formed by at least one set of the claws only via the first discharge port and discharges the gas in the compression pocket formed by at least another set of the claws only via the second discharge port while the pair of rotors rotate one revolution.

摘要： A compressor system includes a screw compressor (48) and a controller (100). The screw compressor includes a slide valve (49) selectively actuatable between a first position and a second position to facilitate modulating a capacity of the screw compressor between fully-loaded and fully-unloaded. The controller is communicably coupled to the slide valve. The controller is configured to receive a chilled fluid temperature setpoint for a fluid in heat transfer communication with a refrigerant of the refrigeration circuit; receive temperature data indicative of a chilled fluid temperature of the fluid; determine a difference between the chilled fluid temperature and the chilled fluid temperature setpoint; and provide one of a load command and an unload command to the slide valve based the difference between the chilled fluid temperature and the chilled fluid temperature setpoint. According to an example embodiment, the controller (100) does not receive feedback from the screw compressor (48) regarding a position of the slide valve (49).

摘要： A refrigeration apparatus includes a compressor and a controller. The compressor has a casing and a compression element. Compressed refrigerant is sent out of the casing after being discharged into an internal space of the casing. An oil sump formed in the casing collects refrigerator oil. A heater heats the refrigerator oil collected. The controller controls the heater while the refrigeration apparatus is stopped so that a temperature of the refrigerator oil collected in the oil sump reaches a first oil temperature target value. The first oil temperature target value is set in order to keep a refrigerant condensation amount of the refrigerant equal to or less than an allowable condensation amount at which the concentration or viscosity of the refrigerator oil needed to lubricate the compressor can be maintained. The refrigerant condensation amount is caused by in-dome condensation at the start of operation of the refrigeration apparatus.

摘要： An oil-cooled gas compressor provided with a compressor body, an oil separator that separates out oil from a compressed gas, a gas pipe for sending the compressed gas, from which oil has been separated out by the oil separator, to a user, and an oil pipe for returning, to the compressor, the oil separated out by the oil separator. An air-cooled heat exchanger for cooling the aforementioned oil, a controllable-speed cooling fan for blowing cooling air at said air-cooled heat exchanger, and a waste-heat-recovery heat exchanger, provided upstream of the air-cooled heat exchanger, for recovering heat from the oil flowing through the abovementioned oil pipe, are also provided. The speed of the cooling fan is controlled so as to bring the temperature of the compressed gas discharged from the compressor body to within a prescribed range. It is possible both to recover waste heat from the oil heated by being used to cool the compressor and to suppress compressor temperature fluctuations, even if the load on the waste-heat-recovery equipment varies.
