PURPOSE:To enable a cooling operation to be performed without increasing a size of a main body of air conditioning machine by a method wherein an opening passage communicating with an electrical component element box and an opening passage communicating with the electrical component box and a negative pressure side in an outdoor air circulation circuit are provided and the outdoor air is flowed in the invertor control part. CONSTITUTION:A partition plate 7 for forming an indoor air circulation circuit 8 and an outdoor air circulation circuit 9 is arranged in a main body of an air conditioning machine. The electrical component box 16 for storing the invertor control device and a capability variable compressor 17 cooperating with the invertor control device are arranged between the partition plate 7 and the indoor air communication circuit 8. Each of the opening passage A for communicating an exterior part of the main body 1 of the air conditioning machine and the electrical component box and an opening passage B for communicating the electrical component box and the exterior air circulation passage 9 are arranged. With this arrangement, the outdoor air is flowed into the invertor control part to cool the invertor control part, then the air is passed through the outdoor air circulation circuit and its heat is radiated out of the room. |
