  As mentioned above, efforts have been made to reduce costs and save labor for buildings themselves, but store facilities such as refrigerated / frozen showcases (hereinafter simply referred to as “showcases”) and air conditioners. The construction of the building, piping, wiring, etc. has not changed since the past. That is, after the building is completed, various facilities are carried in and installed, and duct work, wiring work, piping work, etc. are individually performed on the building. These conventional constructions are less rational than the factory production of building components, the construction contents are complicated, the construction period is long, and there is a lot of wasted space in the building.

  For example, a conventional convenience store showcase is shown in FIG. In FIG. 8, a showcase (open showcase shown) 41 installed along the wall of the store building 40 is provided with a cold air circulation passage 43 surrounding the product display cabinet 42, and a cooler ( Evaporator) 44 is installed. The internal air circulates through the cool air circulation passage 43 through the cooler 44 as shown by the arrow by the operation of the blower 45, and forms an air curtain at the front opening of the showcase. By this circulating cold air, a product (not shown) displayed on the shelf 46 of the product display box 42 is cooled.

  A refrigerator main body 47 that supplies liquid refrigerant to the cooler 44 includes a compressor 48, a condenser 49, a blower 50, and the like, and a refrigerant pipe 51 connects the refrigerator main body 47 installed outdoors and the cooler 44. It is. The high-temperature and high-pressure gas refrigerant discharged from the compressor 48 is sent to the condenser 49 and is condensed by exchanging heat with the outside air ventilated by the blower 50. The generated liquid refrigerant is sent to the cooler 44 and is evaporated by heat exchange with the circulating internal air to cool the circulating air.

  Since such a conventional showcase is configured separately from the store building and is not related to each other, the above-described construction contents are complicated and the facility space is wasted.

  An object of the present invention is to promote integration of a showcase, particularly for a store, with a building, and to save labor in construction and space.

  In order to solve the above-described problems, the present invention includes a cool air circulation passage that surrounds a merchandise display warehouse, a cooler is installed in the cool air circulation passage, and the cooler air is circulated through the cool air circulation passage through the cooler. In the refrigerated / frozen showcase that cools the products displayed in the product display, the showcase body that forms the product display is separated from the cooler, and the wall of the store building is blown through the air duct. The cooler is housed in the wall, and the back surface of the showcase body is connected to the wall so that the cold air circulation passage is formed by the wall and the showcase body ( Claim 1).

  According to the first aspect of the present invention, the wall of the store building is made into a duct and a cooler is installed inside the wall, and the inside of the wall is used as a part of the circulation ventilation path. Can be reduced. In addition, by separating the showcase body that forms the merchandise display case from the cooler portion, it is possible to construct the refrigerant piping before installation of the showcase body, thereby facilitating the piping work. In addition, since the showcase body can be moved regardless of the refrigerant piping, the maintenance and inspection of the cooler can be facilitated, and the modification and replacement of the showcase body by changing the specifications can be facilitated.

  In the invention of claim 1, the coolers corresponding to the plurality of showcase bodies may be connected side by side (invention 2). Thereby, it is not necessary to connect refrigerant | coolant piping separately with respect to each cooler, and piping structure becomes simple. After configuring the plurality of coolers separately, the pipes may be connected to each other, or the whole may be configured integrally.

  In the invention of claim 1, the wall is preferably constituted by a unit panel (invention 2). As a result, a modularized cooler can be incorporated into the panel at the factory production stage of the panel, and the number of on-site assembly steps can be saved.

  In the first aspect of the present invention, the refrigerator main body that supplies the liquid refrigerant to the cooler is separated from the cooler (separately described) (invention 4), or integrally coupled to the back surface of the cooler. (Claim 5). In invention of Claim 5, it is good to provide a window hole in the wall of the said store building, and to insert the said cooler in this window hole so that insertion or removal is possible (Invention 6). Thereby, a cooler can be easily accommodated in the wall of a store building only by inserting the cooler part of a refrigerator into a window hole.

  In the invention of claim 1, the ceiling and floor of the store building in contact with the wall may be configured as a blower duct (invention 7). As a result, it is possible to achieve further space saving such as passing indoor air circulated by the air conditioner through the walls, ceiling and floor of the store building. In the invention of claim 6, the ceiling and floor are preferably constituted by unit panels so as to increase the factory production rate (invention 8).

  According to this invention, the wall of the store building is made into a duct to store the cooler, and the showcase body is connected to this wall, thereby effectively utilizing the internal space of the wall and reducing the showcase installation space. In addition, since the refrigerant piping can be separated from the showcase body, the piping work and maintenance inspection of the refrigerant piping are simplified. Furthermore, since the showcase body can be moved regardless of the refrigerant piping, it is possible to easily cope with modification and replacement accompanying changes in the specifications of the showcase body.
