Abstract: A noise monitor for transmitting an actual sound (noise) when the noise level becomes higher than a regulation standard. In each noise detecting unit, the level of noise is measured through a microphone and a noise meter and input into a radio set. At the same time, an actual sound as noise is input through a microphone and a microphone amplifier into a PHS. In a noise monitoring unit, a PC communicates with the radio set in each noise detecting unit through a radio set to input the noise level measured by each noise detecting unit. The PC determines whether or not the noise level is higher than a regulation standard. If the noise level is higher than the regulation standard, the PC requests a PHS to call the PHS in the specified noise detecting unit to establish the communication between the PHS and the PHS. At this time, a maintenance worker can hear the actual sound from the PHS. Further, the actual sound is recorded by an MD recorder.

Abstract: An expansion valve 1 comprises a prism-shaped body 10, and a valve chamber 20 is formed within the body 10. Refrigerant supplied from a compressor flows into the valve chamber through a passage 22, passes between a valve means 42 and a valve seat 23, and travels toward an evaporator through a passage 24. Refrigerant returning from the evaporator enters the body 10 through a passage 26, and after the refrigerant temperature information is transmitted to the operating shaft 40, the refrigerant flows out through a passage 28 toward the compressor. Passages 22 and 28 open to a first side surface of the body, and passages 24 and 26 open to a second side surface orthogonal to the first surface. Such structure improves the degree of freedom for mounting the expansion valve 1.
