Description

  The present invention relates to an air conditioning system for an in-store merchandise store, and more particularly to a digital smart air control system for a store merchandise store that optimizes a store environment while acquiring temperature information and humidity information of the store merchandise store as digital information.

  Stores in large retail stores such as supermarkets, shopping centers, shopping malls, department stores, etc. are equipped with entrances and exits for many shoppers, a large number of refrigerated and frozen showcases, and a large number of product display fixtures. In general, there are provided a plurality of merchandise counters, a plurality of cash registers, and a plurality of purchased merchandise settlement places where payment and settlement processing of purchased merchandise picked up by the shopper at the merchandise counter is performed. It is a target.

  Conventionally, various proposals have been made for air conditioning equipment that is deployed and employed in such a store counter. For example, Patent Documents 1, 2, and 3.

  If the refrigerated / frozen showcase is an open showcase at a store where a large number of refrigerated / frozen showcases are installed, open it to prevent the cold air inside the refrigerated / frozen showcase from leaking out. An air curtain is provided at the front opening of the showcase from the top to the bottom. The air curtain is circulated from the upper part to the lower part of the cold air intake port, sometimes in a double or triple arrangement.

  A variety of foods and the like are stored in the refrigerated / frozen showcase, for example, 0 ° C. for meat and fresh fish, 5 ° C. for daily food that is delivered daily to stores, and fruits and vegetables 7. The temperature in the refrigerated / frozen showcase is set in accordance with each product stored and displayed in the refrigerated / frozen showcase, such as ℃, frozen food -18 ° C, ice cream -26 ° C, and the like.

  On the other hand, the temperature and humidity of the sales floor are also air-conditioned so as to satisfy predetermined temperature and humidity conditions so that shoppers and the like can feel comfortable and spend time in the sales floor. . For example, the set values of the air-conditioning equipment are such that the sales floor temperature is 26 ° C., the humidity is 50%, and the specific enthalpy is 52.88 kj / kgD.A.

  As mentioned above, even if air curtains prevent cold air from leaking from open refrigerated / frozen showcases, about 3% of cool air leaks from the front opening of the open showcase to the sales floor in the store. Is out.

  For this reason, on the front side of the open-type refrigerated / frozen showcase, the cool air leaking from the front opening of the open showcase stays in a region from the floor to about the height of the human waist. The stagnant cold air spreads over time in the upper and ceiling areas of the sales floor, and in the refrigerated / frozen showcase installation area where the refrigerated / frozen showcase is installed in the merchandise store, the temperature is 14 ° C. to 20 ° C. About ℃.

  Here, in a store counter of a large retail store such as a supermarket, a shopping center, a shopping mall, a department store, or the like, the next period in which the provided air conditioning equipment is operated in the cooling operation mode, for example, a period such as June to September. In this example, the set temperature is set to about 25 ° C. to 26 ° C., and the cooling operation is started when the temperature at the sales floor of the store exceeds the set temperature. A thermostat of an air conditioner detects a change in temperature at a sales floor of a store and operates a cooling operation.

  In this case, as described above, in the refrigeration / freezing showcase installation area where the temperature is about 14 ° C. to 20 ° C., the refrigeration / freezing showcase area provided in the refrigeration / freezing showcase installation area The air conditioner does not operate in the cooling operation.

  When the set temperature of the cooling operation mode is about 25 ° C. to 26 ° C. as described above, the humidity in the refrigerated / frozen showcase which is kept at a low temperature as described above becomes about 70% to 90%, and is refrigerated at the merchandise counter. -Humidity of the refrigerated / frozen showcase installation area where the frozen showcase is installed is also about 63% or more.

  In such an air conditioner of a store, the air exchange between the outside of the store and the store inside the store is performed two to three times an hour by the ventilation equipment, and the air in the store is discharged to the outside. And fresh air outside the store is introduced into the merchandise counter.

  However, as described above, in the refrigerated / frozen showcase installation area where refrigerated / frozen showcases are installed in the merchandise counter, due to the influence of cold air leaking from the refrigerated / freezer showcases, compared to other areas in the merchandise counter. Since the temperature is lower than the set temperature at which the cooling operation of the air conditioner is started in a low-temperature environment, the air flow is not caused by the cooling operation, and the cool air continues to stay.

  In addition, the refrigerated / frozen showcase installation area has a high humidity of 63% or more as described above.

  Then, in the next period when the air conditioner of the store in the store is operated in the cooling operation mode in which the set temperature is about 25 ° C. to 26 ° C., for example, in a period such as June to September, the temperature outside the store exceeds 30 ° C. In general, the humidity exceeds 64%, which is higher than the high humidity of 63% in the refrigerated / frozen showcase installation area described above.

  For this reason, the ventilation equipment for exchanging air between the outside of the store and the product counter inside the store is two to three times an hour in the normal operation mode, and the outside of the store and the product counter inside the store are used. If the air exchange between the air conditioner and the air conditioner is kept at a low temperature of about 14 ° C. to 20 ° C. as described above, the temperature detected by the thermostat of the air conditioner in the area is 14 ° C. to 20 ° C. When the set temperature during the cooling operation is 25 ° C, the air conditioner does not operate in the cooling operation, the low-humidity low-temperature air in the same area stays near the ceiling of the same area, and when the humidity is 63%, refrigeration / freezing The humidity in the ceiling of the showcase installation area becomes higher and higher.

  For this reason, dew condensation on the ceiling of the refrigerated / frozen showcase installation area and the occurrence of mold have been a problem.

  The ceiling surface of the refrigerated / frozen showcase installation area has high humidity, and in June to September, outside air of high temperature and high humidity outside the store flows into the merchandise counter from the entrance when shoppers come to the store. Therefore, dew condensation is constantly generated on the ceiling surface of the refrigerated / frozen showcase installation area. As a result, when the humidity of the indoor environment continues to be 70% or more, a mold is generated.

  Proposals for an effective air-conditioning system that can prevent such dew condensation and mold from occurring have not been sufficient.
