Filed: 1988-01-13
Abstract: PURPOSE:To exhaust a generated harmful gas without lowering an internal pressure by providing a filter, in which a pressure loss is large, in the positive pressure part of an enclosure. CONSTITUTION:Since the inflow of an outside air is executed according to the expansion and contraction of an internal air in a condition in which a pressure in an enclosure 4 is raised at the time of using, a breathing filter 7 needs to be the filter in which the pressure loss is small in a negative pressure part. On the other hand, since the air in the disk enclosure 4 is changed for the outside air in maintaining a condition in which the internal pressure is high by the breathing filter 7, a second exhaust filter 9 is made into the filter which is provided in the positive part and in which the pressure loss is large, namely, in which the air is hard to pass. Thus, by providing the filter in the positive pressure part where the internal air is made to easily go outside, facilitating the change for the outside air, simultaneously, causing the pressure loss to be large and maintaining the internal pressure, the generated harmful gas is discharged to the outside.

IPC: F25B49/02
Filed: 1995-01-19
Abstract: PURPOSE: To provide a freezer device capable of keeping a normal cooling capability without stopping its operation even in the case that a condensing temperature of a condensor is abnormally increased. CONSTITUTION: In the case that a temperature of refrigerant detected by a temperature sensor 8 is less than a predetermined value, a first valve 6 is closed and a second valve 7 is opened. With such an operation as above, refrigerant within a condensor 3 flows through a part of a refrigerant flowing pipe 3a and a bypassing pipe 3b and then condensation is carried out only at a part of the refrigerant flowing pipe 3a. In addition, when a detected temperature exceeds a predetermined value, the first valve 6 is opened and the second valve 7 is closed, and further a fan motor 5a for a blower 5 is rotated at a high speed.  With such an arrangement as above, since the refrigerant in the condensor 3 does not flow through the bypass pipe 3b, but flows toward a terminal end of the refrigerant flowing pipe 3a, condensation is carried out in an entire refrigerant flow passage 3a and then a condensing capability of the condensor 3 is improved. At that time, since the fan motor 5a is rotated at a high speed to increase an amount of blowing air directed toward the condensor 3, resulting in that a cooling effect of the condensor 3 is increased.
