<p><P>PROBLEM TO BE SOLVED: To provide a gas enriching device and an air conditioner using it capable of changing operation rate of a pressure difference generation means in accordance with various conditions for affecting temperature rise of the pressure difference generation means, achieving long service life, and increasing its reliability. <P>SOLUTION: This air conditioner is constituted in such a way that the gas enriching device 1 is provided with at least a gas enriching means (an oxygen enriching unit 2), the pressure difference generation means (a pressure reducing pump 3) for generating difference in pressure in the gas enriching means, and an operation time detection means for detecting operation time of the pressure difference generation means and the pressure difference generation means is intermittently operated based on operation time. Consequently, operation rate of the pressure difference generation means can be changed in accordance with various conditions for affecting temperature rise of the pressure difference generation means, and the gas enriching device having long service life and high reliability can be realized. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
