Description

[Detailed Description of the Invention] The present invention relates to the structure of a store equipped with a frozen or refrigerated open store case.

This type of case generally forms a cold air curtain on the open surface of the case to shield the open surface and cool the inside of the case, so cold air tends to leak out of the case. There is a problem in that the leaked cold air stays on the floor, especially near the case, causing discomfort to the customer.

In addition, in order to cool the inside of the case, a refrigeration circuit is used that repeatedly condenses and evaporates the refrigerant. Conventionally, the refrigerant is condensed by water cooling using a cleaning tower or air cooling using a cleaning fan. The electric motor for driving the water pump and fan requires a large amount of power and water, which is uneconomical.

In view of the above, the present invention has been developed by installing at least a part of the condensing pipe in the refrigeration circuit under the floor of the store corresponding to the area where the cold air flowing out from the opening of the open show case accumulates. The idea is to warm the cold aisle to eliminate customer discomfort, save the energy required to condense the refrigerant, and also use the heat of condensation from the refrigerant to heat the store during the winter, thereby achieving energy savings. .

Examples will be described below with reference to the drawings.

In Figure 1, there are several open shop cases 2-1, 2-2,...2-5 inside the store 1.
is installed. The interior of these open show cases is cooled by a refrigeration circuit that repeatedly condenses and evaporates refrigerant. That is, each open case has its own evaporator 3.
-1, 3-2, ... 3-5 are built in, and come out from the receiver (or condenser including the receiver) 4 installed outside the store 1 and reach the compressor 5 also installed outside the store 1. The evaporators 3-1, 3-2, . . . 3-5 are connected to the refrigerant pipe 6 in parallel with each other. Furthermore, Compressa 5
At least a part of the condensing pipe 7 coming out of the store and reaching the receiver 4 is installed buried under the floor surface of the store 1. At this time, the portion of the condensing pipe 7 corresponding to the portion between the two cases is made to meander.

In such a store 1, the floor surface is warmed by the heat of condensation of the refrigerant, so the store case 2
The cold air leaking from -1, 2-2, ...2-5 will also be warmed, eliminating the discomfort of customers caused by cold aisles, and cleaning towers, cleaning fans, etc. will be needed to condense the refrigerant. Since it is unnecessary or requires only a very small amount, the energy required for condensation is saved. Additionally, in the winter, the condensed heat of the refrigerant can be used to heat the store.

Also, since the condensation pipe is installed under the floor,
It does not become an obstruction in the store and does not spoil the aesthetic appearance.

Although the above description has been made using specific embodiments, the present invention can be modified in various ways, and these modifications are of course included in the present invention.
