ロックＤ内の上部に配置された熱搬送手段である。2. Description of the Related Art Conventionally, this type of outdoor unit has been constructed as shown in FIG. That is, in the lower part of the casing body 21, there is an outdoor heat exchanger block C1 in which an outdoor heat exchanger 22 and an outdoor fan 23 are arranged, and a compressor block D in which a compressor 25 in which a heating heater 24 is mounted. A heater block E is provided in the upper part of the casing body 21, in which a refrigerant heater 26 and a burner tube 27 are arranged. Further, inside the casing body 21, a horizontal partition plate 28 is provided for partitioning the heater block E, the outdoor heat exchanger block C, and the compressor block D, and the outdoor heat exchanger block C and the compressor block A vertical partition plate 29 is provided for partitioning the space from D.

、室外熱交換器２２および室外ファン２３は運転されて
いない状態になっている。According to the above configuration, during the cooling operation, the compressor 25 is operated to perform the cooling cycle. That is, the outdoor fan 23 is driven to cause the outdoor heat exchanger 22 to radiate heat from the refrigerant.
A cooling effect was obtained by condensing the air and then absorbing heat and evaporating it in an indoor unit (not shown). In addition, during heating operation, in order to reduce power consumption, the compressor 25 is stopped, the refrigerant is heated and evaporated by the refrigerant heater 26, and the high-temperature refrigerant gas is transported to the indoor unit via the heat transport means 30. and had a heating effect. Therefore, in this case, the outdoor heat exchanger 22 and the outdoor fan 23 are not in operation.

題があった。Problems to be Solved by the Invention However, according to the above configuration, the size of the outdoor fan 23 is determined by the size of the outdoor heat exchanger 22.
In order to secure the necessary air volume, the number of rotations of the outdoor fan 23 must be increased, which poses a problem of increased noise.

加するという問題があった。In addition, the outdoor heat exchanger block C in which the outdoor heat exchanger 22 and the outdoor fan 23 are arranged is not heated during heating operation, and has a temperature that is approximately equal to the outside air temperature, so that the refrigerant during the heating cycle As a result, the refrigerant accumulated in the outdoor heat exchanger 22 needs to be returned to the heating cycle, which inevitably increases the number of pump-down operations in which the compressor 25 is operated for a certain period of time. In order to prevent such a situation as much as possible, the compressor 25 is preheated by the heater 24, but there is a problem in that when the outside temperature drops, the power consumption of the heater 24 increases. .

い。Effects According to the above configuration, during heating operation, the refrigerant heater heats and evaporates the refrigerant, and the compressor conveys this high-temperature refrigerant gas to the indoor unit to obtain a heating effect. In addition, an outdoor fan with a diameter larger than the height of the outdoor heat exchanger can be installed by using the recessed part of the partition plate, and therefore there is no need to increase the rotation speed of the outdoor fan, thereby reducing noise. I can do it. In addition, since the partition plate is formed with a concave portion, its strength can be increased, and rainwater and the like can be collected and discharged easily, thereby making it possible to prevent corrosion and deterioration as much as possible. Furthermore, during heating operation, the compressor is heated by both radiation from the surface of the refrigerant heater and convection, so power consumption of the heating heater can be suppressed even when the outside temperature is low. Furthermore, since the refrigerant heater is disposed at the lower part of the casing body, even if fuel such as kerosene leaks, restarting the operation will not be hindered.
