IPC: F04B39/00
Filed: 1992-10-07
Abstract: PURPOSE:To obtain an air conditioner which can be easily assembled because of small number of parts, and does not affect the work environment. CONSTITUTION:A non-woven fabric noise absorbing member 19 made of long acrylic fibers 21 and long polypropylene microfibers 20 having finer fiber diameters than the fiber 21 is formed so as to surround a compressor 18 housed inside a box 12 of an exterior unit 11. Since the noise absorbing member 19 is made of the non-woven fabric prepared by entangling the long fibers, it is possible to prevent scattering the fine fibers in a working field when the noise absorbing member 19 is manufactured or the compressor 18 is surrounded. Since the fibers are not connected to each other by using a binder such as phenol resin, ion causing corrosion of the metal is not generated when wet by water, so that it is unnecessary to arrange a water-proof member between the compressor 18 and the noise absorbing member 19. Work environment is not affected, and assembling work is facilitated because of small number of parts.

Abstract: PURPOSE:To attain a normal clamping action with no malfunction caused by noises by using a filter to extract a frequency component higher than the prescribed frequency of the error voltage and offsetting the high frequency component contained in the error voltage against an output signal by the output of the filter. CONSTITUTION:A comparator 3 compares the output of a level shift circuit 2 with the reference voltage in the period of the clamp pulse and produces the error voltage.
