Description

  The present invention relates to an exhaust heat treatment apparatus, and more particularly to an apparatus for treating the exhaust heat of a refrigerator in a showcase disposed in a store room such as a convenience store.

  Conventionally, for example, Patent Document 1 proposes an exhaust heat treatment apparatus for treating the exhaust heat of a refrigerator in a showcase disposed in a store room. In this waste heat treatment device, the showcase is disposed in an area that divides the store from the backyard, and when the air conditioner installed in the store performs heating operation, the air in the backyard or the store is displayed. The heating load of the air conditioner was reduced by passing the air around the refrigerator of the case to collect the exhaust heat of the refrigerator in the air and then supplying it to the circulation duct of the air conditioner.

Japanese Patent Laid-Open No. 7-12446

  By the way, in the exhaust heat treatment apparatus proposed in Patent Document 1 described above, the air that has passed around the refrigerator is supplied to the circulation duct of the air conditioner, so that it is useful in stores equipped with so-called circulation type air conditioners. For example, it is difficult to apply in a room where a non-circulating air conditioner is installed like a small store, and as a result, it may be difficult to reduce the heating load of the air conditioner.

  In view of the above circumstances, an object of the present invention is to provide an exhaust heat treatment apparatus capable of reducing the heating load of the air conditioner regardless of the form of the air conditioner.

  In order to achieve the above object, an exhaust heat treatment apparatus according to the present invention is an apparatus for treating the exhaust heat of a refrigerator built in a showcase disposed inside a store room, and has been introduced. Air supply means for supplying air to the refrigerator, and air that has passed through the periphery of the refrigerator by being driven are installed in the chamber in the vicinity of the area where the counter for performing the product checkout process is performed in the chamber. The air-conditioning apparatus is provided with exhaust means for sending it out through the outlet in at least one of the vicinity of the air inlet of the air conditioner.

  In the exhaust heat treatment apparatus according to the present invention, the air supply means introduces air inside the chamber through an introduction port disposed near the front surface of the showcase.

  In the exhaust heat treatment apparatus according to the present invention, the exhaust means sends out air that has passed through the periphery of the refrigerator through a delivery port in the vicinity of a region where the counter is disposed in the chamber. Is characterized in that it is formed in the region directly above the counter in a manner that its longitudinal direction coincides with the longitudinal direction of the counter.

  Moreover, the present invention is characterized in that, in the above-described waste heat treatment apparatus, the refrigerator is disposed at an upper portion of the showcase.

  According to the present invention, the air introduced by the air supply means is supplied to the refrigerator to absorb the exhaust heat of the refrigerator, and the exhaust heat of the refrigerator passes through the periphery of the refrigerator by driving the exhaust means. Since the discharged air is sent to at least one of the vicinity of the counter arrangement area and the vicinity of the air inlet of the air conditioner through the outlet, the air that has passed around the refrigerator by the exhaust means is in the vicinity of the counter arrangement area. In the case of delivery to the store, high-temperature air can be intensively supplied in the vicinity of the counter with the longest stay time of the store clerk in the store room. Thereby, it is not necessary to heat the whole inside air of a store room by an air conditioner.

  On the other hand, when the air that has passed around the refrigerator is sent to the vicinity of the air inlet of the air conditioner by the exhaust means, the sent air is sucked through the air inlet of the air conditioner and heated to blow out into the room. The inside air of the chamber can be heated. That is, the exhaust heat of the refrigerator in the showcase can be used for heating the air inside the chamber.

  Therefore, it is possible to reduce the heating load of the air conditioner regardless of the form of the air conditioner.

The exhaust heat of the 20 refrigerators 22 can be processed as follows.

  When the air supply fan 32 is driven, air in the vicinity of the front surface of the showcase 20 (air inside the chamber 11) is introduced into the air supply line 31 through the introduction port 33. The air introduced into the air supply line 31 is supplied to the refrigerator 22 of the showcase 20 by the air supply fan 32. The air supplied to the refrigerator 22 exchanges heat with the refrigerator 22 while passing around the refrigerator 22 to absorb the exhaust heat of the refrigerator 22 and become high temperature. The air that has absorbed the exhaust heat of the refrigerator 22 by driving the exhaust fan 35 passes through the exhaust line 34 and is sent to the inside of the chamber 11, that is, in the vicinity of the counter 14 through the outlet 36.

  As described above, according to the exhaust heat treatment apparatus according to the first embodiment of the present invention, the internal air of the chamber 11 introduced through the inlet 33 by driving the air supply fan 32 is surrounded by the refrigerator 22 of the showcase 20. The exhaust heat of the refrigerator 22 is absorbed and the exhaust fan 35 is driven to absorb the exhaust heat of the refrigerator 22 and send it through the outlet 36 in the vicinity of the area where the counter 14 is disposed. Therefore, high-temperature air can be intensively supplied in the vicinity of the counter 14 having the longest residence time in the room 11 of the store 10. Thereby, it is not necessary to heat the whole internal air of the room 11 of the store 10 by the air conditioner 13. Therefore, regardless of the form of the air conditioner 13, the heating load of the air conditioner 13 can be reduced.

  According to the exhaust heat treatment apparatus, since the inlet 33 is formed near the front surface of the showcase 20, the air near the front surface of the showcase 20 is driven to the air supply line 31 through the inlet 33 by driving the air supply fan 32. It can be introduced and supplied to the refrigerator 22 of the showcase 20. Thereby, the air in the vicinity of the front surface of the showcase 20 in which the cool air leaked from the storage chamber 21 of the showcase 20 can be effectively used, and the temperature drop of the cool air pool in the showcase 20 is alleviated and the air conditioner The heating load of 13 can be further reduced, and energy saving of the entire store 10 can be achieved.

  According to the exhaust heat treatment apparatus, since the delivery port 36 is formed in a mode in which the longitudinal direction coincides with the longitudinal direction of the counter 14 in the region immediately above the counter 14, air is sent from the delivery port 36 to the periphery of the counter 14. The speed can be moderately suppressed. Moreover, the air sent out from the outlet 36 can function as an air curtain that partitions the periphery of the counter 14 and the sales floor of the chamber 11.
