  As shown in FIG. 2, the heat exchange system 20 is a liquid-cooled heat exchange system, and includes an evaporator (evaporator) 21, a compressor 22, a condenser (condenser) 23, and an accumulator 24. The heat exchange system 20 includes a refrigerant cycle 25 including an evaporator 21, a compressor 22 and a condenser 23. The refrigerant cycle 25 circulates the refrigerant, thereby absorbing heat by the evaporator 21 and performing heat exchange (transfer of heat) in which the heat is released by the capacitor 23. In this example, the refrigerant cycle 25 is formed so that the refrigerant passes in the order of the evaporator 21, the accumulator 24, the compressor 22, and the condenser 23, and the refrigerant flows into the evaporator 21 again.

  In this showcase device 1, the evaporator 21 is arranged in the second storage portion 12 so as to cool the second display chamber 12 a by the heat absorption of the evaporator 21, and the capacitor 23 is a third display by the heat dissipation of the capacitor 23. It arrange | positions at the 3rd accommodating part 13 so that the inside of the chamber 13a may be heated. In this example, the evaporator 21 is disposed in the machine room 12x surrounded by the heat insulating wall 51 below the second display chamber 12a, and the capacitor 23 is formed by the heat insulating material 51 below the third display chamber 13a. Arranged in the enclosed machine room 13x. Further, the accumulator 24 and the compressor 22 are disposed in the second machine room 13y that is not covered with the heat insulating material below the machine room 13x.

  As shown in FIG. 3, an air outlet 32a is provided from the machine room 12x to the lower rear side of the second display room 12a. A suction port 32b to the machine room 12x is provided in front of the lower side of the second display room 12a. The lower front of the second display chamber 12a may be the air outlet 32a, and the lower rear may be the air inlet 32b. The machine room 12x is provided with a fan 32c for blowing air at a position facing the evaporator 21, and by driving the fan 32c, the cool air cooled by the heat absorbed by the evaporator 21 is contained in the second display chamber 12a. Supplied and circulated.

  An air outlet 33a is provided on the lower rear side of the third display chamber 13a from the machine room 13x. A suction port 33b to the machine room 13x is provided in front of the lower side of the third display room 13a. The lower front of the third display chamber 13a may be the air outlet 33a, and the lower rear may be the air inlet 33b. A fan 33c for blowing air is provided at a position facing the condenser 23, and when the fan 33c is driven, the warm air heated by the heat radiation (exhaust heat) of the condenser 23 in the machine room 13x is third. Is supplied into the display chamber 13a and circulates.

  In the showcase of this example, Δt due to heat absorption of the evaporator 21 is about −20 to −15 ° C., and Δt due to heat dissipation of the capacitor 23 is about 25 to 30 ° C. The amount of heat radiated from the condenser 23 includes the heat generated by the compressor 22 in addition to the heat absorbed by the evaporator 21, that is, the amount of heat accompanying the work for the compressor 22 to compress the refrigerant. Accordingly, if the room temperature is about 25 ° C., the inside of the first display chamber 11a is about 25 ° C. (room temperature), the inside of the second display chamber 12a is about 5 ° C. to 10 ° C. (low temperature), and the third display chamber 13a. The inside can be set to about 50 ° C. to 55 ° C. (high temperature). Furthermore, it is possible to heat the third display chamber 13a using the amount of heat released from the compressor 22 to the outside.

  Since the showcase device 1 has a matching load on the heat absorption side and the heat dissipation side, the heat transfer of the refrigerant cycle 25 of one heat exchange system 20 requires other systems and structures (such as heaters). First, the low and high temperature conditions as described above can be realized. Therefore, processed food products 101 to 103 such as side dishes are not used in high-temperature exhaust heat (exhaust gas) or low-temperature exhaust heat (exhaust gas) in air-conditioned stores such as convenience stores. Can be displayed while being stored at a suitable temperature, that is, normal temperature is normal temperature, cold is cold, and warm is warm. Similarly, even if it is other than a convenience store, for example, food displayed in a buffet-style restaurant can be displayed while cold food is cold and warm food is stored warm.

  In addition, a touch panel type information display device (for example, a liquid crystal display) 41 is provided on the front side of the housing 10 and below the first to third display chambers 11a to 13a. The information display device 41 can display information on the products 101 to 103 displayed in the first to third display chambers 11a to 13a (voices of producers, attention to ingredients, etc.). Yes.

  As the tray 50 for taking out and placing the products 101 to 103, for example, a tray with a heat retaining function can be used. By doing in this way, goods 101-103 can be taken home at a suitable temperature (for example, a warm thing is a warm state). The products 101 to 103 are each put in a box or the like, and the box is provided with an authentication means such as a barcode. The showcase device 1 is provided with a reading device 42 that reads the authentication means. After the product is selected, the tray 50 is measured (the product selected through the tray 50 is authenticated), and the meal balance and calories are calculated. It is recorded on the receipt 43 and output.

  As described above, according to the showcase device 1, the second display chamber 12a can be cooled by the heat absorption of the evaporator 21, and the third display chamber 13a can be radiated by the heat of the capacitor 23 (low temperature). From the viewpoint of forming the second display chamber 12a, the interior of the third display chamber 13a can be heated by exhaust heat of the condenser 23).

  In other words, considering the conditions of refrigeration and warming of food, the showcase device 1 has a balanced load for maintaining the conditions of the heat absorption side (refrigeration display side 12) and the heat dissipation side (warm display side 13). is doing. For this reason, in the showcase device 1, the low temperature display chamber 12 a and the high temperature display chamber 13 a can be obtained by heat transfer of one refrigerant cycle 25. Therefore, the showcase device 1 does not require a structure such as another system or a heater other than the single heat exchanging system 20, and further refrigerates without generating high-temperature or low-temperature exhaust heat that increases the load of air conditioning. And you can realize warm storage. Considering the display of food, there are usually cases where the load (Δt) on the refrigeration side is larger than the load (Δt) on the refrigeration side, so that the machine room on the refrigeration side can cope with such a case. A heater may be provided at 13x. Furthermore, heating the display chamber 13a on the storage side including heat radiation from the compressor 22 or the like is important in order to effectively use the heat transfer of the refrigerant cycle 25 and maintain the temperature on the storage side.

  Further, according to the showcase device 1, the second display room 12a for displaying the second food and drink 102 at a low temperature and the third display room 13a for displaying the third food and drink 103 at a high temperature. Between, the 1st display room 11a for displaying the 1st food and drink 101 at normal temperature is arrange | positioned. For this reason, the 1st display room 11a exhibits the 1st food-and-drink 101 at normal temperature, and the function which insulates well between the low temperature 2nd display room 12a and the high temperature 3rd display room 13a Also plays.

  Furthermore, according to this showcase apparatus 1, since the 1st thru | or 3rd display chambers 11a-13a are arrange | positioned in the horizontal direction (lateral direction), all the 1st thru | or 3rd food-drinks 101-103 are.
