Description

Indoor evaporator of refrigeration tower {A evaporator of the refrigeration tap}

The present invention relates to a wall-mounted indoor unit mounted on a refrigeration tower of a refrigerating vehicle. More specifically, the box-shaped indoor unit is mounted on the front plate of the freezing tower to expand a loading space inside the freezing tower, and upper both sides of the box-type casing. The present invention relates to a wall-mounted indoor unit of a freezing tower capable of preventing air intake of an indoor unit from being blocked by forming an air suction hole therein.

In general, the indoor unit mounted inside the freezing tower refers to a device that circulates the air inside the freezing tower and converts it into cold air. The inside of the freezer is forcibly circulating the evaporator and the internal air of the freezing tower to lower the temperature of the air. The rotating fan to be mounted.

Thus, Figure 6 is a schematic diagram showing a refrigerator vehicle equipped with a conventional refrigeration apparatus, first described the configuration as follows.

First, the conventional refrigeration apparatus, the outdoor unit 101 mounted on the front outside of the freezing tower 100 and the inside of the freezing tower 100 to circulate the air inside the freezing tower 100 to cool the circulating air The indoor unit 200 is configured.

Particularly, the indoor unit 200 includes a casing 201 having an air inlet 202 through which internal air is introduced, and an air outlet 203 formed at a rear thereof so as to discharge cold air. An evaporator 208 mounted on the air inlet 202 side, which is an interior front of the 201, and an air circulation unit 204 mounted on the rear of the evaporator 208 to circulate air.

The air circulation unit 204 includes a drive motor 206 horizontally mounted to the rear of the evaporator and a rotation fan 205 mounted to the rotation shaft 207 of the drive motor 206.

Therefore, the operation relationship of the indoor unit 200 configured as described above is as follows.

First, the refrigerant is operated to supply refrigerant to the evaporator 208 constituting the indoor unit 200, and at the same time, the drive motor 206 of the air circulation unit 204 mounted at the rear of the evaporator 208 is operated to rotate. Rotate fan 205.

When the rotating fan 205 is rotated as described above, the internal air of the freezing tower 100 is forced to the evaporator 208 through the air inlet 202 formed in the lower portion of the casing 201 of the indoor unit 200. In addition, the air passing through the evaporator 208 is converted into cold air, and then is supplied to the inside of the freezing tower 100 again through the air outlet 203 formed at the rear of the casing 201. .

However, the indoor unit configured as described above has a problem that the internal space of the freezing tower is relatively reduced by being protruded and mounted on the front upper side of the inside of the freezing tower.

In addition, since the indoor unit protrudes above the front of the freezing tower, the space immediately below the indoor unit cannot be used when the tray or the pallet is mounted, and thus, a large number of the stacker and the pallet cannot be loaded.

In addition, since the air suction hole is formed only in the lower part of the indoor unit, when the loading box and the like come into contact with the lower part of the indoor unit, the flow of air is blocked, thereby lowering the freezing efficiency of the freezing tower.

Meanwhile, the conventional evaporator is mounted vertically and the direction of the wind is perpendicular to the evaporator, so that the temperature of the inlet pipe of the evaporator is increased and the temperature of the outlet pipe is lowered, so that the temperature of the inlet pipe is increased. The pressure drops as the temperature rises and conversely the temperature of the discharge pipe drops.

Therefore, since the refrigerant is concentrated only in the direction of decreasing pressure, the refrigerant in the inlet pipe is insufficient and the refrigerant in the discharge pipe is excessive, so that uniform cooling cannot be achieved when the air passes.

Therefore, the present invention is designed to solve the above problems, by making the indoor unit of the present invention into a box shape and mounting it on the front plate of the freezing tower, the built-in indoor unit of the wall of the freezing tower which can expand the loading space inside the freezing tower. For the purpose of providing it.

In addition, by mounting the indoor unit to the front plate of the freezing tower as described above, there is also an object that can increase the number of loading of the loading box or pallet having a restriction on the height.

In addition, by forming air intake holes on both sides of the upper portion of the box-shaped casing, there is also an object that can prevent the air intake of the indoor unit is blocked due to the loading box.

In addition, by separating a plurality of refrigerant pipes mounted on the evaporator from each other so that the refrigerant is distributed and supplied to each refrigerant pipe, so that the amount of refrigerant packed in the refrigerant pipe can be balanced when the inflow air is raised, thereby cooling the air. There is also a goal to maximize efficiency.

The present invention for achieving the object as described above, in the refrigeration tower comprising a front plate; The front plate is formed with a square hole; The square hole is equipped with a box-shaped casing in which a vertical bulkhead having an open lower portion is mounted on both sides thereof, and an air ascending passage is formed between the vertical bulkheads, and an air descending passage is formed on both sides of the vertical bulkhead; The rear plate of the box-shaped casing, at least one air discharge hole in communication with the air rise passage in the center of the upper portion, the lower air suction hole in communication with the air rise passage in the lower center, the upper air communication with the air down passage on both sides An upper air suction hole is formed; The outdoor unit protruding outward is mounted on the front plate of the box-shaped casing; An evaporator is mounted at the center of the air ascending passage and a blower fan for forcibly circulating air is mounted at the upper part of the evaporator; The air descending passage is characterized in that the various devices constituting the indoor unit is mounted.
