It is not directly related to temperature control. The cooler 4 of the refrigerator compartment 2 is stopped. The heating fan 7 and the heating fan 8 are operated to heat the refrigerating chamber 2. At this time, cold air flows into the greenhouse 3, but since the heater 5 is operated, the temperature inside the greenhouse 3 is hardly affected.

運転して冷却時間を短縮しても良い。It is possible to operate both fans 7 and 8 at the same time, although it is possible to raise the temperature of the refrigerating room 2 only by the heating fan 8, but it takes time and both fans 7 and 8 are operated simultaneously. This is because the heating time can be shortened, and when cooling the greenhouse 3, the fans 7 and 8 can be operated simultaneously to shorten the cooling time.

According to the present embodiment, as described above, the heating fan 7 that blows the air inside the refrigerating compartment 2 toward the greenhouse 3, and the heating that blows the air inside the greenhouse 3 toward the refrigerating compartment 2. With a fan 8
The control device 10 operates the heating fan 7 and the heating fan 8 to circulate air between the refrigerating compartment 2 and the greenhouse 3 when at least the temperature in the refrigerating compartment 2 is lower than a predetermined temperature.

ることができる。As a result, it is possible to reduce the manufacturing cost by reducing the number of heaters 5, which are conventionally provided also in the refrigerating compartment 2, the number of control devices including the hot water circulation path W and other pipes, and the hot water valve 55. . Further, by eliminating the heater 5 in the refrigerating compartment 2, the device portion can be downsized and the luggage compartment capacity can be increased.

定温度に制御することが可能となる。The refrigerating compartment 2 is used in a temperature range of about 0 ° C., and the greenhouse 3 is used in a temperature range of about 20 ° C.
As described above, both the refrigerating room 2 and the warming room 3 are not the low temperature room but the low temperature room and the high temperature room are adjacent to each other, and the indoor temperature is set to the set temperature by using the air having a large temperature difference between the other. It becomes possible to control.

This is effective in the present invention in the small-sized heat insulation refrigeration equipment 1, and the small heat insulation refrigeration equipment 1 secures a sufficient luggage compartment capacity and a space for carrying luggage even in a small car and the like, and effectively uses the luggage carrier space. It is suitable because it can be installed at low cost with a heat insulation refrigerator.
