The above is explained in more detail as follows.

The vapor collecting apparatus 100 of the present invention includes a compressor 20, a condenser 30, an expansion valve 40, an evaporation trap 50, a controller (not shown) 70) are safely stored.

The case 10 has an upwardly opened internal storage space and an upper end portion thereof is opened and closed by a cover 12 and is provided with a carrying handle and the like and includes a vapor supply port 14 and a vapor discharge port 16 So that the vapor supply pipe is connected from the outside.

In addition, the present invention is characterized by comprising: an upper cover (12) for opening and closing a storage space of said case (10); A hinge (17) for connecting one side of the cover (12) to the case (10) and the other fixing means; And a control unit. One side of the cover 12 is coupled to the upper end of the case by a hinge 17 and is opened up. The other side of the cover 12 is provided with fixing means such as a one-touch buckle and a clamp.

As shown in FIG. 3, the compressor 20 is placed in the upper part of the inside of the case 10 and sucks the low-temperature and low-pressure refrigerant through the refrigerant circulation pipe 22, compresses the refrigerant to a high pressure and sends it to the condenser 30.

The condenser 30 is provided with a plate heat exchanger on the right side of the inner compressor of the case 10 and exchanges heat between the refrigerant flowing in the first heat transfer channel and the cooling water flowing in the second heat transfer channel of the plate heat exchanger, To a low temperature state.

According to the present invention, the condenser 20 has a plate-like heat exchanger vertically attached to a first bracket 38 fixed to the bottom surface, and a cooling water supply pipe 35 and a cooling water outlet 36 connected to the cooling water inlet 34, And an end of the cooling water discharge pipe 37 connected to the discharge pipe 37 is exposed to the outer surface of the case 10 and pipe connecting means is provided at the end of the supply pipe 35 and the discharge pipe 37. That is, the cooling water supply pipe 35 and the discharge pipe 37 are connected to the right side cooling water inlet 34 and the outlet 36 of the plate heat exchanger, respectively. The cooling water supply pipe 35 and the discharge pipe 37 are exposed upward through a horizontal plate 19 partially formed at an upper end edge of the case and connected to the pipe connecting means through a cooling water supply and recovery line from the outside .

The expansion valve 40 is provided between the condenser and the steam trap and adiabatically expands the low-temperature refrigerant from the condenser 30 at a low pressure to improve the condensing efficiency of the vapor in the subsequent evaporation trap 50.

The evaporation trap 50 is accommodated in the center of the inside of the case 10 and flows through the first heat transfer passage and the evaporation trap 50 through the vapor inlet 52 and the vapor outlet 54 of the plate heat exchanger, 40 is passed through the third refrigerant inlet 56 and the fourth refrigerant outlet 58 to the second heat transfer channel of the plate heat exchanger to mutually exchange heat and the generated condensed oil flows through the drain 60 at the bottom Downward. That is, as the vapor flowing into the first heat transfer channel of the plate heat exchanger and the cold refrigerant flowing into the second heat transfer channel are exchanged with each other, the vapor is cooled and condensed at a low temperature, and the condensed condensed oil flows down the flow hole And discharged downward through the drain 60 on the right bottom surface. The remaining gas (residual vapor) is then discharged to the vapor outlet 16 through the vapor outlet and the second connection hose. Particularly, the plate heat exchanger is a multi-layer structure in which thin heat exchange plates (heat transfer channels) having a CHEVRON (V-shaped pattern shape) angle are laminated in a multi-stage structure. The heat contact area through the heat exchange plates is expanded, The condensation efficiency and the recovery rate of the vapor are very high.

According to the present invention, the evaporation trap 50 is installed horizontally in the second bracket 48 on the bottom surface, and the first and second evaporator traps 50, 52, and 54, which are coupled to the vapor inlet 52 and the vapor outlet 54 of the plate heat exchanger, The end of the two connecting hoses 53 and 55 is exposed to the outer side of the case 10 and piping connecting means is provided at the end of the end of the connecting hose 53 and 55. In other words, the evaporation trap 50 is coupled to a second bracket 48 fixed to the bottom surface 11 and supported laterally at a constant height spaced from the bottom surface, and a third refrigerant inlet 56 is provided at the bottom, And the fourth refrigerant outlet 58 and the drain 60 pipe are connected. The first connection hose 53 is coupled to the vapor inlet 52 located at the left edge of the upper surface and the second connection hose 55 is connected to the vapor outlet 54 at the other edge. The first and second connection hoses 53 and 55 are made of flexible flexible hoses so that they are flexibly bent when the cover is opened or closed and are easily assembled with the oil supply port and the discharge port.

At the end, the vapor supply port 14 and the discharge port 16 are connected to the case or the cover and the first and second connection hoses 53 and 55 are selectively coupled to each other. So as not to leak.

According to another aspect of the present invention, the pipe connection means is selected from a flange, a clamp band, a one-touch fitting, a coupling, and a union. As shown in the figure, the clamp band 80 surrounds the pipe connecting portion (flange) with a band and is fixed by the fastening force of a bolt and a nut (butterfly nut). The one-touch fittings, couplings, and unions described above, which are not shown in the drawings, are embodiments of known piping connecting means that can be implemented by a general engineer, and a detailed description thereof will be omitted.

According to the present invention, the vapor outlet (54) is provided with a temperature sensor (90) for detecting the temperature of the vapor. That is, the temperature sensing sensor 90 senses the temperature of the gas (vapor) that exits through the steam trap to the outlet and transmits the sensed signal (temperature) to the controller 70, And controls the operation (ON / OFF). For example, when the temperature of the vapor (refrigerant) falls below a predetermined temperature (0 ° C), the controller 70 turns off the compressor to prevent freezing of the vapor (refrigerant).

According to the present invention, the vapor outlet (54) is formed with a sensor coupling portion (92) on a side surface of a pipe connection port. As shown in FIG. 4, the sensor coupling portion 92 is inserted through the side of the pipe connecting port of the right side vapor outlet 54, and the pipe connecting port is integrated by brazing while being inserted into the hole of the outer cover plate of the plate heat exchanger . It is easy to detach and attach the temperature sensor 90 through the sensor coupler 92, and it is convenient to inspect and maintain the sensor sensitive to the temperature change.

The present invention may also be applied to an evaporation pressure regulating valve (64) and a liquid separator (66) provided between the compressor (20) and the evaporation trap (50). And a control unit. The evaporation pressure control valve (EPR 64) controls the flow of gas refrigerant entering the compressor from the steam trap to maintain the pressure of the refrigerant at a constant level and to produce a desired temperature. In other words, if the evaporation pressure from the steam trap is higher than the suction pressure of the compressor, it is opened. If the evaporation pressure is lower than the suction pressure, the steam trap is kept at a constant pressure to increase the condensation efficiency. The liquid separator 66 separates the refrigerant to prevent a liquid back to the compressor, thereby preventing overloading and preventing the pressure (refrigerant) in the vapor trap 50 from being disturbed, thereby improving the condensing efficiency .

Next, the controller 70 is disposed on the inner front side of the case, and an operation panel having a power supply for power supply, a power switch 72, an operation switch 74, and the like is exposed forward. The power supply unit is provided with a power switch 72 and is configured to supply external power through a power line 76 or power supply means such as a rechargeable battery to be always powered. An automatic or manual operation switch (button) for operating the compressor, a warning lamp and a speaker for visually or audibly displaying the operation state of the apparatus, and a thermometer.

FIG. 5 is a perspective view of a vapor collecting apparatus according to another embodiment of the present invention. The controller 70 is attached to the outer surface of the case 10 and the upper surface of the cover 12 to facilitate operation and maintenance. Lt; / RTI >
