The present invention relates to a showcase with a built-in cooling device.

Generally, a showcase is a product installed with a refrigeration system so that food or other items can be kept fresh and stored for a long time. The showcase is classified into a refrigerated or frozen showcase according to the food being stored. Showcases are mainly installed in supermarkets, large stores, shopping centers, etc., so that the manager can take out the food from the inside when the consumer selects the product to buy while looking inside.

In addition, the showcase is horizontally installed to display and take out goods upwards and vertically to display and take out goods to the front. In addition, the door is installed at the entrance and there is an open type to form an air curtain without installing the door.

5 is a schematic configuration diagram of a cooling apparatus of a conventional general refrigeration showcase, wherein the cooling apparatus is composed of a compressor, a condenser, an expansion valve, and an evaporator, and a controller for controlling the same is a temperature value and a set temperature value of a temperature sensor installed in a refrigerating chamber. When the temperature is higher than the set temperature, the compressor is driven and refrigeration is performed by driving a cooling fan for circulating cold air generated by the evaporator. That is, when the temperature of the refrigerating compartment is higher than the set value, the compressor and the cooling fan are driven, and the refrigerant compressed by the compressor at high temperature and high pressure is condensed in the condenser, and the refrigerating compartment is kept at a low temperature through the expansion valve and the evaporator.

However, the conventional refrigeration showcase cooling device has the following problems.

First, when the compressor capacity is increased, the noise emitted from the compressor is rapidly increased. In most cases, when a large capacity compressor is used, it is installed outside the showcase, that is, the outdoor unit. As such, when the outdoor unit is installed, various problems arise such as excessive cost and inefficient use of space.

In addition, the failure in the cooling system is mainly caused in the compressor, a problem that can not use the goods stored in the showcase during the repair of the compressor.
