摘要： A centrifugal blower including a casing formed with a discharge port and a suction port, and an impeller mounted in the casing and having a plurality of backwardly curved vanes arranged circumferentially of the impeller. The suction port has a semicircular suction member located in spaced juxtaposed relation to a semicircular curled portion formed at the forward end of a shroud of the impeller. An annular guide plate may be attached to the inner side of the suction member and formed at its open end with a wall portion disposed along the shroud which is formed at its forward end with an annular wall extending into a space defined between the suction member and the guide plate. Hair may be provided on one of opposed wall surfaces of the suction member and the annular wall of the shroud.

摘要： An active noise control system for a three-dimensional space, including noise detecting means, sound generating means, noise control effect detecting means and a control device consisting of a phase of a wave signal fed from the noise detecting means wherein a plurality of noise control effect detecting means and sound generating means are disposed at a distance shorter than a wavelength of the noise to be controlled, and input signals of the respective sound generating means and output signals of the respective noise control effect detecting means are fed through filters, separately, to control the sound for active noise control. In case of an air conditioner, the noise control effect detecting means are disposed at positions where an air stream flowing through the air conditioner is not obstructed thereby.

摘要： An air conditioning system including at least one water-cooling type air conditioning unit, a heat pump chilling unit, an ancillary heat exchanger in said water-cooling type air conditioning unit, and a cold and heat accumulating tank divided into two tank sections differing from each other in volume and the temperature of water contained therein. In a cooling mode, cold water of relatively high temperature and cold water of relatively low temperature are accumulated by operating the heat pump chilling unit at night, and when a normal heating operation is performed, the cold water of relatively high temperature is used as cooling water for a condenser of the water-cooling type air conditioning unit and when the water-cooling type air conditioning unit is inoperable as when power failure occurs at peak load, the cold water of relatively low temperature is supplied to the ancillary heat exchanger to carry out cooling. In a heating mode, warm water of relatively high temperature and warm water of relatively low temperature are accumulated by operating the heat pump chilling unit at night, and at startup in a heating operation, the warm water of relatively high temperature is supplied to the ancillary heat exchanger to start the heating operation, and in a normal heating operation, the warm water of relatively low temperature is directly used as a heat source water for a water side heat exchanger of the air conditioning unit or as a heating heat source.
