PROBLEM TO BE SOLVED: To facilitate installation of an air conditioner in a roof space and make a sufficient restriction of increasing in temperature of some electrical component parts by a method wherein an electrical component part storing box for storing the electrical component parts to control the air conditioner is arranged at a lower part of a dew receiving pan and an aeration passage for use in air-cooling the electrical component parts is formed. SOLUTION: A heat exchanger 7 and a heat exchanger oscillating dew receiving pan 8 are arranged between a partition plate 5 and a blowing port 3. An electrical component part storing box 9 for storing electrical component parts to control an air conditioner is arranged at one side of a lower part of the dew receiving pan 8. A ceiling plate of the electrical component box 9 and a bottom part of the dew receiving pan 8 are being contacted to each other, wherein the electrical component box 9 is indirectly cooled with cold water flowing down from the heat exchanger 7. In addition, a bottom surface of the main body 1 positioned at a front lower part of the other side of the electrical component box 9 is provided with an opening 11 for taking air of air-conditioned room and then an aeration passage 12 is formed between the opening 11 and a blower 6. The electrical component box 9 is air-cooled with air flowing in the aeration passage 12 and at the same time at least a forward or rearward wall of the electrical component box 9 is provided with a plurality of electrical holes so as to improve an electrical operation so as to restrict an increasing in temperature of the stored electrical components. |
