Next, the operation of the hot water and hot air boiler using the three-phase motor according to an embodiment of the present invention configured as described above will be described with reference to the accompanying drawings.

First, when an AC power is applied to the three-phase motor 10 by switching on a power switch (not shown) of the control unit 120, the shaft 10a of the three-phase motor 10 is rotated as the three-phase motor 10 rotates. Drive pulley 21 installed in the rotation.

When the driving pulley 21 rotates, the belt 23 suspended between the driving pulley 21 and the driven pulley 22 is rotated at the same time, so that the rotational force of the driving pulley 21 is transmitted to the driven pulley 22. The driven pulley 22 rotates accordingly, and thus the turbo blower shaft 40b in which the driven pulley 22 is installed is rotatably supported by a bearing (not shown) installed in the cooling chamber 42. The blower shaft 40b rotates.

At this time, since the tension of the belt 23 is constantly adjusted by the tension adjusting means 25 on the fixed shaft 24a of the idle lever 24, the rotation speed of the turbo blower 40 is controlled by the control unit 120. And the turbo blower 40 rotates as the turbo blower shaft 40b rotates to suck the outside air A from the filter 43, and to be contained in the outside air A. Filtered foreign matter (or dust) is filtered by the filter 43, and the filter 43 receives the air filtered by the foreign matter, and the direct current power or the alternating current power is supplied to the first heater 46 through the first power supply terminal 45. ), The first heater 46 begins to dissipate heat.

As the first heater 46 begins to dissipate heat, primary heating is performed by heat radiated from the first heat radiating fins 46a disposed in parallel with each other at a predetermined interval on the outer circumferential surface of the first heater 46. The air is heated to discharge the primary heating air through the first heating air discharge pipe 47.

As described above, the first heating air discharged through the first heating air discharge pipe 47 is introduced into the turbo blower 40 to be heated secondarily by the heat generated by the rotation of the turbo blower 40 and thus to the second heating air. The secondary heating air is discharged through the heating air discharge pipe (41).

As the secondary heating air heated hot in the turbo blower 40 passes through the second heater 70, the DC power or AC power is applied to the second power terminal 72 of the second heater 70. Third heating is performed by heat radiated from the second heat radiating fins 70a disposed at a predetermined interval on the outer circumferential surface of the second heater 70.

The tertiary heating air heated by the third heater 70 is introduced through the circulating water inlet 60a while passing through the heat exchange pipe 63 of the heat exchanger 60 to exchange heat of the heat exchanger 60. The hot water (or hot water) that heat-exchanges the water flowing through the outer circumferential surface of the pipe 63 is introduced into the heat exchange tank 80 through the hot water discharge port 60b and the hot water discharge pipe 60c.

The hot water (or hot water) introduced into the heat exchange tank 80 is injected through the water inlet 80a, and the heating water warmly heat-exchanging the water stored in the heat exchange tank 80 is not illustrated through the heating water outlet 80b. It is possible to heat the space to be discharged and heated in a heating pipe, for example, indoors, greenhouses, baths, agricultural and marine product drying rooms, fish farms, and the like.

The warm air of 55 to 75 ° C. whose temperature is dropped by warmly heat-exchanging water flowing through the outer circumferential surface of the heat exchanger pipe 63 of the heat exchanger 60 is a hot air outlet 65 and a hot air discharge pipe 69 of the heat exchanger 60. The space to be heated through, for example, indoors, greenhouses, bathrooms, agricultural and marine products drying room, fish farms can be used for heating.

On the other hand, the circulating water injected into the heat exchange tank 80 through the water inlet 80a is pumped by the circulation pump 90 through the circulating water discharge pipe 92 and the circulating water inlet 60b. 60) is introduced into.

In addition, the secondary heating air heated hot in the turbo blower 40 is formed of hot heated air according to the opening area of the valve 100 installed in the feedback pipe 41a branched from the second heating air discharge pipe 41. By the heat generated by the rotation of the turbo blower 40 is introduced into the turbo blower 40 together with the primary heating air introduced through the first heating air discharge pipe 47 by interrupting (or adjusting) the amount of feedback. By heating again, the temperature can be heated higher.

The heated tertiary heating air introduced into the heat exchanger 60 flows in a plurality of heat exchange pipes 63 disposed parallel to each other along the longitudinal direction in the heat exchanger 60, and is fixed to the outer circumferential surface of the heat exchange pipe 63. Receive the guides of a plurality of guide plates 64 zigzag along the longitudinal direction at intervals to heat the water flowing zigzag along the arrow A direction to heat the heat exchange tank through the hot water outlet (60b) and hot water discharge pipe (60c) Discharge into 80.

In other words, since the secondary heating air hotly heated in the turbo blower 40 is discharged through the second heating air discharge pipe 41, DC power or AC power is applied to the second power terminal 72. As the second heater 70 generates heat, it is heated again by heat radiated from the second heat radiating plate 70a disposed in parallel to the outer circumferential surface of the second heater 70, thereby introducing the heating air inlet of the heat exchanger 60 ( Through 62 is introduced into the heat exchanger (60).

The hotly heated tertiary heating air introduced into the heat exchanger 60 flows through a plurality of heat exchange pipes 63 disposed parallel to each other in the heat exchanger 60 along the longitudinal direction, and is fixed to the outer circumferential surface of the heat exchange pipe 63. Receives guides of a plurality of guide plates 64 provided at intervals to warmly heat the water flowing zigzag along the arrow A direction and is introduced into the heat exchange tank 80 through the hot water outlet 60b and the hot water discharge pipe 60c. .

The hot water introduced into the heat exchange tank 80 is formed in the heat exchange tank 80 by heating water that warmly heat-exchanges the water injected into the heat exchange tank 80 through the water inlet 80a of the heat exchange tank 80. A space to be discharged and heated in a heating pipe (not shown) through the heating water outlet 80b may be used for heating, for example, indoors, a greenhouse, a bathroom, a farm / aquatic product dryer, or a fish farm.

The hot water (or hot water) introduced into the heat exchange tank 80 warmly heat-exchanges the water injected into the heat exchange tank 80 through the water inlet 80a of the heat exchange tank 80 so that the water whose temperature has dropped is circulating water. It is introduced into the heat exchanger 60 through the circulating water discharge pipe 92 and the circulating water inlet 60a by the pumping of the circulating pump 90 installed in the discharge pipe 92 and heat-exchanged again as described above. .

On the other hand, the hot air heated in the turbo blower 40 is the turbo blower 40 through the feedback pipe 41a branched from the second heating air discharge pipe 41 and the valve 100 installed in the feedback pipe 41a. It is mixed with the primary heating air passing through the first heating air discharge pipe 47 through the inlet (40a) of the) is introduced into the turbo blower 40 is heated more hot.

At this time, it is possible to adjust the amount of the heated air fed back according to the opening degree of the valve 100 installed in the feedback pipe (41a) branched from the second heating air discharge pipe (41).

When the valve 100 is narrowly opened, the amount of air heated by the turbo blower 40 is fed back through the feedback pipe 41a so that the heating temperature of the air is higher than when the valve 100 is opened wide. Of course, heating is low.

When the pressure in the heat exchange tank 80 is higher than the preset pressure or the temperature in the heat exchange tank 80 is higher than the preset temperature, the safety valve 110 is opened to open the pressure or temperature in the heat exchange tank 80. By lowering the safety accident can be prevented.

On the other hand, a bearing (not shown) for rotatably supporting the turbo blower shaft 40b in the cooling chamber 42 when heat generated as the turbo blower 40 rotates is transferred to the cooling chamber 42. At the same time, excessive heat is applied to a mechanical seal (not shown) that supports both ends of the turbo blower shaft 40b to be hermetically sealed. However, the present invention may deteriorate the cooling heat exchanger 56. The cooling liquid is supplied into the cooling chamber 42 through the cooling liquid supply pipe 56a by pumping the cooling liquid pump 57 installed in the cooling liquid supply pipe 56a of the cooling liquid to cool the turbo blower shaft 40b, the mechanical seal and the bearing. Therefore, these deformations can be prevented.

In addition, the coolant supplied into the cooling chamber 42 is cooled after the turbo blower shaft 40b, the mechanical seal, and the bearing are cooled, and then the coolant is discharged to the coolant tank 55 through the coolant recovery pipe 55a. After being discharged to the cooling heat exchanger 56 through the discharge pipe 55b and cooled, it is pumped by the coolant pump 57 installed in the cooling liquid supply pipe 56a of the cooling heat exchanger 56 as described above. Cooling liquid is supplied into the cooling chamber 42 through the cooling liquid supply pipe 56a to cool the turbo blower shaft 40b, the mechanical seal and the bearing.
