  • Patent number: 8225619
    Abstract: The present invention provides a technique for rapidly removing frost accumulated in air-refrigerant cooling apparatuses. An air-refrigerant cooling apparatus in accordance with the present invention includes a bypass line for directly supplying a defroster with refrigerant air having an increased temperature from a compressor, avoiding temperature drop by a heat exchanger and an expansion turbine. Moisture of the frost melted in the defroster is externally exhausted by a fan.

  • Patent number: 8141380
    Abstract: The purpose present invention is to provide an air refrigerant type cooling apparatus provided with an internal air cooling mechanism with high reliability and efficiency. Another object of the present invention is to provide an air refrigerant cooling/heating system with a simplified configuration using the air refrigerant type cooling apparatus. 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.

  • Publication number: 20100313596
    Abstract: 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.

  • Patent number: 7601760
    Abstract: The present invention provides a method for decomposing a plastic so as to recycle useful substances therefrom as raw materials for a similar plastic. In particular, the present invention provides a method for decomposing a plastic, comprising the step of treating a thermosetting resin comprising a polyester and its crosslinking moiety, with subcritical water of a temperature lower than the thermal decomposition temperature of the thermosetting resin. According to the present invention, the thermosetting resin can be decomposed into a polyhydric alcohol, a polybasic acid and a compound comprising an acid residue derived from the polyester and a residue derived from the crosslinking moiety, without causing a random decomposition of the thermosetting resin.

  • Patent number: 7541427
    Abstract: An objective of the present invention is to provide a desolvation method for removing a solvent efficiently from a polymer solution. In the present desolvation method where the solvent is removed from the polymer solution by steam stripping using an apparatus comprising a pipe which connects a gas phase portion of a desolvation tank at the downstream and a liquid phase portion of a desolvation tank at the upstream, and an opening-degree adjusting mean (for example, pressure adjusting valve) fixed to this pipe, pressures are controlled such that a pressure difference (?P=P2?P1) between pressures of each gas phase portion of desolvation tanks at the downstream and at the upstream is allowed to be larger by from 0.005 to 0.6 MPa, preferably from 0.05 to 0.3 MPa than a pressure difference when the opening-degree adjusting mean is fully opened.
