Description

[Detailed description of the invention] This invention relates to a refrigeration system, and more specifically, it relates to a humidifying refrigeration system that introduces water vapor generated when defrosting water is evaporated into the refrigerator to prevent the humidity inside the refrigerator from decreasing. It is something.

Refrigerators for storing fruits, vegetables, and meat are required to have an internal humidity of 80% or more.

However, when a refrigerator is in operation, the air inside the refrigerator is cooled and dehumidified at the same time, so the interior of the refrigerator becomes dry, causing fruits and vegetables to wither and lose their freshness, and meat to dry out, discolor, and lose weight. There was a drawback that I ended up doing it.

Therefore, in fruit and vegetable refrigerators, water spray,
Centrifugal humidifiers are used in meat refrigerators, and steam-generating humidifiers are used to maintain the relative humidity inside the refrigerator at 85 to 90%. However, the percentage of relative humidity when the humidifier is not in use differs depending on the temperature of the refrigerator and usage conditions, and it is difficult to make a general decision, but by increasing the area of the cooler, the temperature difference between the cooler and the inside of the refrigerator can be increased. (TD) or adopt a reverse cycle defrosting method using a four-way valve to shorten the defrosting cycle, and use a fan to return the condensate on the surface of the cooler fins to the inside of the refrigerator during defrosting. This is known as a method of increasing the humidity inside the refrigerator.

Using a humidifier or increasing the area of the cooler as in the former case has the disadvantage of high equipment costs.

This invention aims to eliminate the above-mentioned drawbacks, and its feature is that most of the moisture dehumidified by the cooler is used for humidification, and it is attached to the refrigerant circulation pipe. A humidifying type that increases the humidifying effect by forming a large number of cut and raised edges on one or both sides of the fins to prevent water droplets attached to the fins from flowing down. The company provides refrigeration equipment.

An embodiment of this invention shown in the drawings will be described in detail below.

Figures 1 and 2 show an embodiment of this invention, in which an evaporator fin 2 is attached to a refrigerant cycle connected to a compressor and a condenser (not shown).
In addition to providing the refrigerant evaporation tubes 1 in a staggered manner,
A rectangular cut-and-raise claw 4 with the cut-and-raised side facing upward is cut and raised on one side or both sides of a thin plate-like fin between the holes or on both sides of the hole.

Note that these cutting and raising claws may be cut and raised at the same pitch and at the same position in each stage as in the embodiment, but it is also possible to set the cutting and raising claws in each stage by shifting them by 1/2 pitch in the width direction. Alternatively, the fins may be provided not only on one side of the fin but also on both sides alternately for each stage.

By providing the cut and raised claws 4 on the fins 2 in this way, the frost adhering to the fins 2 is melted by defrosting (by off-cycle, water spray, hot gas, or heater method), and water droplets flow down along the fin surfaces. This is prevented by the cut and raised claws 4, and water droplets adhering to the fins during the defrosting operation humidify the refrigerator to restore the humidity inside the refrigerator, which was lost during operation of the cooler. Additionally, by additionally installing a humidifier with a small capacity, the humidity inside the refrigerator can be maintained even higher.

As mentioned above, this invention forms a large number of cut-and-bevels on one or both sides of the fins attached to the refrigerant circulation pipe, with the ends facing upward, to prevent water droplets attached to the fins from flowing down. It is designed to increase the humidifying effect by
The cooler of the refrigeration equipment is used as a cooler and a humidifier, and the defrosting water obtained from defrosting is used as water for humidification, so the humidity inside the refrigerator that is taken away by the operation of the refrigeration machine can be defrosted. It is possible to eliminate the need for drying the inside of the warehouse by returning it to the warehouse, and it also has effects such as lower equipment costs and easier maintenance.
