Abstract

(57) [Abstract] [Purpose] To obtain a refrigerating device having a function of preventing a decrease in indoor temperature in winter or the like by utilizing exhaust heat of a condenser. [Structure] A damper 10 for selectively blowing out hot air that has been heat-exchanged by the condenser 4 indoors or outdoors.
A duct having is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refrigerating device which has a compressor, a condenser, a blower, and the like in a casing and cools and freezes foods and the like.

[0002]

[Prior Art]

 2 and 3 are a front view and a side view showing an example of an outdoor unit of a conventional refrigeration system. In the figure, 1 is a casing, 2 is a compressor fixed on a bottom plate in the casing 1, 3 is a partition plate arranged above to protect the compressor 2 from rain and dust, 4 The condensers (4) and (5) above which heat-exchanges the high-temperature refrigerant from the compressor 2 with air, sucks this air from the air suction port 1A provided in the casing 1, and from the air outlet port 1B. It is a blower arranged to blow out.

FIG. 4 is a refrigerant circuit diagram showing an example of the refrigerant circuit of the refrigerating apparatus as described above. The refrigerant compressed by the compressor 2 becomes high temperature and high pressure, and heat is exchanged with the air in the condenser 4, that is, the exhaust gas is discharged. It is heated and further expanded (decompressed) by the expansion device 6 to be in a low temperature and low pressure state where it is easily vaporized. FIG. 5 is an explanatory diagram showing an example of use of the refrigerating apparatus as described above, in which the refrigerant in the condenser 4 exchanges heat with the air sucked from the air suction port 1A by the blower 5. At this time, the heat-exchanged air having a high temperature is discharged from the air outlet 1B into the atmosphere. On the other hand, the refrigerant becomes low temperature and low pressure and flows into a cooler 8 such as a showcase 7 arranged indoors to evaporate, that is, cool the surrounding air to cool or freeze foods or the like.

[0004]

[Problems to be solved by the device]

 Since the conventional refrigeration system is configured as described above, if there is a person in the room where the showcase 7 is installed, the room temperature will be lowered in the winter and the like, so a heating system is required, but condensation As a result, the heat-exchanged air in the container 4 was discharged to the outside of the room.

The present invention has been made to solve the above problems, and obtains a refrigerating apparatus having a function of preventing a decrease in indoor temperature such as in winter by utilizing exhaust heat of a condenser. The porpose is to do.

[0006]

[Means for Solving the Problems]

 The refrigerating apparatus according to the present invention is provided with a duct that selectively discharges the air, which has been heated by the condenser and has a high temperature, indoors or outdoors.

[0007]

[Action]

 In the refrigerating apparatus according to the present invention, when the room needs to be heated, the air that has been heated by the condenser and has a high temperature is introduced into the room to prevent the temperature from decreasing.

[0008]

【Example】

 An embodiment of this invention will be described below with reference to FIG. This figure is an explanatory view of a usage example showing an embodiment of the present invention, in which 9 is a duct, and the air that has become high temperature due to heat exchange in the condenser 4 is placed above the air outlet 1B. Is blown out into the duct 9. Further, a damper 10 is provided inside the branch portion of the duct 9, and the damper 10 is driven within a range indicated by a solid line and a broken line around the shaft 11, and the showcase 7 and the like are arranged in the winter season. When the room temperature in the room is lowered and it is necessary to prevent the room temperature from lowering or to heat the room, it is fixed at the position indicated by the broken line, and otherwise fixed at the position indicated by the solid line. As a result, the high-temperature air blown into the duct 9 is redirected by the damper 10 when room temperature reduction prevention or heating is required, and is blown into the room through the air outlet 9A provided in the room, thereby reducing the room temperature. It is possible to prevent deterioration and obtain a heating effect. In other cases, since the damper 10 is inverted to the position indicated by the solid line, the high temperature air blown into the duct 9 is discharged into the atmosphere through the air outlet 9B. The function for cooling or freezing food or the like is the same as the conventional one, and therefore the description thereof is omitted.

[0009]

As described above, according to the present invention, the duct is provided so as to selectively discharge the air, which has become high temperature due to heat exchange in the condenser, into the room or the room as occasion demands. Since the temperature drop is prevented and there is also a heating effect, it is not necessary to install a heating device in the room, and the equipment cost can be reduced.
