The operation of the air conditioner configured as described above will be described.

When the air conditioner 1 of the present invention is operated, in the cooling operation, the refrigerant is compressed to a high temperature and high pressure state by the compressor 2, liquefied by the outdoor heat exchanger 4, and liquefied by the dryer 5 to water, dust and metal powder. Contaminants such as are removed and reach the indoor heat exchanger 6 through the indoor side capillary tube 11. After the refrigerant takes heat from the surrounding air and evaporates in the indoor heat exchanger 6, the refrigerant passes through the accumulator 10 and returns to the compressor 2, thereby performing air conditioning by cooling.

In the heating operation, the refrigerant is compressed to a high-temperature and high-pressure state by the compressor 2, liquefied in the indoor heat exchanger 6, and reaches the outdoor heat exchanger 4 through the outdoor capillary tube 11. At this time, contaminants such as moisture, dust, metal powder and the like are removed from the refrigerant by the dryer 5.
After the refrigerant takes heat from the surrounding air and vaporizes in the outdoor heat exchanger 4, the refrigerant passes through the accumulator 10 and is
It is designed to perform a cycle of returning to.

Further, in this operation state, the fan 23 of the indoor unit 13 rotates in conjunction with the operation of the compressor 2, sucks indoor air into the indoor unit 13, and after the indoor heat exchanger 6 Is blowing out that air. At this time, when the air passes through the filter 12, the odor, bacteria and mold contained in the air are deodorized and sterilized by the filter 12.

According to the present embodiment, the following operation
The odor component, bacteria and mold attached to the filter / heat exchanger can be removed, and the replacement time of the fluorescent lamp for photocatalyst can be displayed.

When the power of the air conditioner 1 is turned on, the odor sensor 17 of the air conditioner 1 detects the odor level contained in the sucked air as shown in step 2, and this odor level is equal to or higher than a predetermined value (predetermined value). Stronger). If the odor is equal to or higher than the predetermined value, the fluorescent lamp control means 22 sends a signal to the fluorescent lamp energizing means 18 as shown in step 4, the fluorescent lamp energizing means 18 energizes the fluorescent lamp 19, and the ultraviolet region is applied to the filter 12. Is irradiated.

At this time, the holes generated on the surface of the photocatalyst 16 react with the water adsorbed on the surface of the photocatalyst to generate hydroxyl radicals, and the hydroxyl radicals cut molecular bonds of organic substances to decompose odorous substances. Can be deodorized. When the air containing the odorous substance is passed through the filter 12, the odorous substance is adsorbed by the adsorbent 15 or comes into direct contact with the photocatalyst 16 which has developed the oxidative decomposition power by the hydroxyl radicals, and finally, Decomposed into water and carbon dioxide.

During this energization, each energization time to the fluorescent lamp 19 is calculated by the energization time integrating means 31, and the number of energizations to the fluorescent lamp 19 is calculated by the energization number calculation means 32. The fluorescent lamp replacement display means 33 calculates a value obtained by dividing the cumulative power-on time sent from the power-on time integrating means 31 and the power-on frequency calculating means 32 by the power-on frequency, and determines whether to send electricity to the fluorescent lamp 19 based on the value and the cumulative power-on time. It is determined whether or not (step 5). If the calculated value requires replacement of the fluorescent lamp 19, the fluorescent lamp replacement display means 33 displays replacement of the fluorescent lamp 19 (step 8).

When the value obtained by dividing the cumulative power-on time by the number of power-on times is equal to or less than a predetermined value (one power-on time is short), the odor sensor 1
7 checks the odor level of the air sucked into the indoor unit 13, and if the odor level is smaller than a predetermined value (the odor is weaker than the predetermined value), the fluorescent lamp control means 22 transmits a signal to the fluorescent lamp energizing means 18. , Fluorescent lamp energizing means 18
Stops power supply to the fluorescent lamp 19 (step 7).

As a result, the effect of not only decomposing odorous substances adhering to the filter by the action of the photocatalyst but also removing bacteria and molds adhering to the filter 12 can be obtained.
Further, the energizing time integrating means 31 calculates the integrated energizing time to the fluorescent lamp 19, and the number of energizing times to the fluorescent lamp 19 is calculated by the energizing number calculating means 32. When calculating the value obtained by dividing the cumulative power-on time sent from the power-on frequency calculating means 32 by the power-on frequency, the fluorescent lamp replacement display means 33 determines whether or not to display the fluorescent lamp replacement based on the value and the cumulative power-on time. The accuracy of the replacement time of the fluorescent lamp 19 can be improved. In addition, regarding the determination of the replacement of the fluorescent lamp 19, the measurement is very simple and does not cause any error because only the integrated energizing time and the number of energizing times are measured. Further, when the fluorescent lamp 19 needs to be replaced, the fluorescent lamp replacement display means 33 is turned on, so that the effect of reliably replacing the fluorescent lamp 19 can be obtained.
