CONSTITUTION:A partition plate 4 placed between a chamber 2 of a heat exchanger and a chamber 3 of a compressor is provided with a recess 22. A radiation plate 28 is disposed at the chamber of the heat exchanger. Some electrical component parts 30 are disposed at a chamber of a compressor. A relay 25 having an engaging part 27 to be engaged with a recess 22 of a partition plate is disposed between the radiation plate 28 and the electrical component parts 30. The radiation plate 28 becomes a part of the partition plate so as to accomplish a complete partition for bath chambers. In addition, a thermal radiation effect is promoted by a blower 6 within the heat exchanger. The engaging part 27 is removably attached, so that the internal electrical component parts can be easily repaired and maintained.
