摘要： The object of the present invention is to cool an inside space of cooling warehouse uniformly by using a air refrigerant type cooling apparatus. A piping for taking in air in the cooling warehouse is installed. The air taken in by the piping (higher temperature) is mixed by the air sent from the air refrigerant type cooling apparatus (lower temperature) and blown off to the cooling warehouse. The temperature of the mixed air is closer to the temperature inside of the cooling warehouse than the air sent from the air refrigerant type cooling apparatus so that the inside of the cooling warehouse is cooled more uniformly. Furthermore, the amount and speed of the air blown off into the cooling warehouse are increased so that the inside space of the cooling warehouse is more uniformly cooled.

To accomplish the purpose, a heat radiating means is provided in a motor of an air refrigerant type cooling apparatus having a compressor, the motor and an expansion turbine in the present invention. Also, a pressure difference is positively generated between the inside and outside of the motor. By these means, when the motor is driven, the heat from the stator main body is exhausted to the outside of the motor through the heat radiating means and the heat from the coil end portions is exhausted through the cooling air exhausted from the inside to the outside of the motor. Further, a guide plate is located adjacent to the cooling air inlet in the motor, so that the intake cooling air is efficiently guided to the stator coil end portions. By this means, the heat generated from the coil end portions is efficiently exhausted from the inside to the outside of the motor. According to these configurations, an air refrigerant cooling apparatus can be realized. Moreover, by installing the air refrigerant cooling apparatus to a cooling/heating system, an air refrigerant cooling/heating system having simple configuration and very high reliability can be provided.

摘要： An object of the present invention is to provide an air refrigerant cooling apparatus having magnetic bearings with high reliability and high efficiency. In the present invention, magnetic bearings are applied to a motor of an air refrigerant cooling apparatus which includes a compressor, the motor and an expansion turbine. To remove contamination moving into the inside of the motor from the outside through a labyrinth, a pressure difference is generated between the inside of the motor and the compressor. Thus, high-speed rotation is kept, and an air refrigerant cooling apparatus with high reliability and high efficiency can be attained. Provided near the magnetic bearings are sensors for detecting positions of the shaft in the radial and the axial directions. To prevent the sensors from being exposed to the air refrigerant leaked from the compressor and the expansion turbine through labyrinth, a pressure difference is also generated between the space where the sensors are provided and the outside of the motor. Thus, the sensor operation is stabilized. An air refrigeration system having high reliability and high efficiency with a simple configuration is attained by incorporating the air refrigerant cooling apparatus into a refrigeration system.
