Title: Air conditioner
Inventor: NISHIDA SHUICHI
IPC: F24F11/02
Filed: 1991-12-26
Abstract: PURPOSE:To obtain an air conditioner which improves an operability of altering an operation mode and has means for fundamentally ensuring switching to a normal operation mode from an emergency operation mode for a trial operation. CONSTITUTION:When an operation/stop switch 4 is set to an operation side while closing a plurality of normal open switches 1 (and 2) used also as a manual defrosting function, it is altered to an emergency operation mode. On the other hand, when it is set to the emergency operation mode, if the switch 4 is set to the stop side or a power source is interrupted, it is automatically returned to a normal operation mode. The alteration of the operation mode is simplified, and it is not necessary to pay an attention to failure to return from the emergency operation mode to the normal operation mode.

Title: Extinguishing method
Inventor: MURAKAMI KOJI
IPC: A62D1/00
Filed: 1991-12-27
Abstract: PURPOSE:To achieve extinguishing performance surpassing a halide chemical without incurring the breaking of an ozone layer by injecting dichloropentafluoropropane to an object to be extinguished in a liquid to extinguish to ensure excellence in fouling of the machine after extinguishment and compactness. CONSTITUTION:A liquid dichloropentafluoropropane [HCFC-225 (C3HCl2F3)] is used as extinguishing chemical which is injected to an object to be extinguished to extinguish. The HCFC-225 is limited in toxity with a very small ozone breaking coefficient (0.01-0.04). Because a latent heat (boiling point) of vaporization and a saturation vapour pressure are as low as 33.4cal/g and 0.4kg/cm<3> respectively, in the use under a normal temperature, the chemical can be injected to the object to be extinguished in a liquid and gasified after the extinguishment. Thus, this method is free from problems of breaking ozone layers and fouling of the machine after the extinguishment like a powder or an aqueous solution and thus, assures excellent extinguishing performance.
