Title: Air-conditioner and its inspecting or measuring method
Inventor: SUMINO MASAHIRO
IPC: F24F11/02
Filed: 1995-01-23
Abstract: PURPOSE: To shorten a time necessary for the inspection or the measurement of the performance or the quality of an air-conditioner by a method wherein the air-conditioner is operated under a special operating condition, different from the ordinary air conditioning operation while at least one of the inspection or the measurement can be effected by the special operation. CONSTITUTION: When a special signal exclusive for inspection, which is different from a signal used for the ordinary control of the air-conditioner, is received from a receiving unit during an operating switch 4 provided in an indoor machine 1 is being pushed, the operating condition of the indoor machine becomes different from the ordinary air-conditioning operation. Only a fan in the indoor machine 1 is rotated with the maximum capacity whereby the vibration of the indoor machine 1 becomes maximum. The vibration of the indoor machine at that time is measured and a product, whose vibration at that time becomes higher than a given level, is screened as a defective product. According to this method, the inspection or the measurement of the performance or the quality of the indoor machine can be effected within a short period of time.  Further, the special signal can be received only during the operating switch, provided in the indoor machine, is being pushed whereby a possibility, wherein a signal of other product is received and the indoor machine is shifted into a special operating condition by mistake, becomes very small and the property of safety of the product can be increased.

When this measuring instrument becomes the tolerance setting mode, a bar graph extending from '0' to +50 of the plus side is displayed on the analog display part 24, and said instrument becomes the upper limit tolerance set state. In this state, the upper limit value is set by operating the + side moving switch 30D and moving the lower limit of the display bar in the plus direction. When setting of the upper limit is ended, a bar graph (0--50) of the minus side is displayed, therefore, this time the lower limit value is set in almost the same way as the foregoing by operating the - side moving switch 30C.
