The water channel direction is adjusted by the operation of the electric motor 700 described later.

Again, the shape of the channel direction adjuster 600 is not limited to a circular shape, and may be formed in various shapes, and the scope of the right channel should not be limited.

As described above, the heating water can be circulated in the forward direction or the reverse direction through the four channels provided in the water direction controller 600,

First, during the forward circulation, the heating water is circulated sequentially through the water supply pipe 100, the first water passage 31, the water distributor 800, the water collector 810, the third water channel 33 and the recovery pipe 110, The heating water circulates through the water supply pipe 100, the second water channel 32, the water collector 810, the water distributor 800, the fourth water channel 34 and the recovery pipe 110 in the reverse direction.

Specifically, the water channel direction adjuster 600 is installed in the case 900, and four connecting ports provided in the water channel direction adjuster 600 The water supply pipe 100 is connected to the water supply pipe 100, the water distributor 800, the water collecting unit 810 and the return pipe 110. For convenience of explanation, the water supply pipe 500, the water distributing pipe 510, (520), and a return pipe connection port (530).

Referring to a process of operating the heating water circulation control system according to the present invention,

The electromagnetic valve 200 provided in the water supply pipe 100 is always open and the water supply connection port 500 and the water supply connection port 510 of the water flow direction adjuster 600 are connected to the first water channel 31 And the collector connection port 520 and the return pipe connection port 530 are connected to the third water channel 33 so that when the heating water is drawn through the water supply pipe 100, the water supply connection port 500, the first water channel 31, The water is circulated to the water distributor 800 through the water connector 510 and circulated to the water collector 810 connected to the water distributor 800 to be returned to the collector connector 520 and the third water channel 33, 530 and the recovery pipe 110, which are referred to as forward circulation.

The heating water circulation control system according to the present invention analyzes the data of the first temperature sensor 400 provided in the water supply pipe 100 and the second temperature sensor 410 provided in the recovery pipe 110, The electromagnetic valve 200 is closed to reduce the pressure of the circulating water pipe and then the command is transmitted again to operate the electric motor 700 installed in the water channel direction adjuster 600 to rotate the water channel direction adjuster 600 do.

At this time, the controller 300 is installed in the case 900, and the electric motor 700 is installed in the waterway direction adjuster 600 to guide the rotation of the waterway direction adjuster 600.

The water channel connector 500 and the water collector connector 520 of the channel direction adjuster 600 are connected to the second water channel 32 and the water channel connector 510 is connected to the water channel connector 500, And the return pipe connection port 530 are connected to the fourth water channel 34 so that the heating water flows through the water supply pipe 500 and the second water channel 32 and the collector connection port 520 The water is circulated to the water collector 810 and circulated to the water distributor 800 connected to the water collector 810. The water is circulated through the water separator connector 510 and the fourth water channel 34 and the return pipe connector 530, (110), which is referred to as reverse circulation.

When the temperature data measured by the first temperature sensor 400 and the second temperature sensor 410 reaches a preset value of the controller 300, the controller 300 transmits a command to the solenoid valve 200 So that energy can be saved by supplying or interrupting the water supply of the heating water.

Also, the range of the temperature setting and the range of the water quantity setting are not limited and can be set manually according to the environment of each area, or the temperature data can be analyzed and automatically controlled by the controller 300, The scope of the rights should not be construed as limiting.

As described above, the heating water circulation control system according to the present invention automatically analyzes the temperature data set by the user in the control unit 300 and the data fed back from the first and second temperature sensors 410, It is possible to control the system precisely by adjusting the circulation direction.

Also, although not shown in the drawings, a monitor capable of visually outputting data and status, etc. may be included, and the scope of the right should not be limited.

The present invention is also applicable to a structure in which a conventional water supply pipe 100, a water distributor 800, a return pipe 110 and a water collector 810 are connected without changing a heating water supply and recovery method from a conventional heat source generating facility The water circulation control system of the present invention may be installed to automatically adjust the circulation direction. In general, the water is circulated from the unidirectional circulation to the water collector 810, Circulated to be recovered to the water distributor 800 and the heating water is conveyed to the heating zone in the reverse direction, thereby achieving the object of energy saving by improving the heat transfer efficiency.

The method of supplying the heating water using the circulation direction system as described above includes a brief temperature measurement step P1, a pressure reduction step P2, a waterway direction control step P3, a heating water supply step P4, And a heating water cutoff step (P5).

More specifically, the temperature measuring step measures the feed water temperature through the first temperature sensor 400 of the water pipe 100 and the recovered temperature through the second temperature sensor 410 of the return pipe 110 , The circulation direction of the heating water can be determined by the change or difference in the feed water temperature and the recovery water temperature.

When the temperature is measured and the circulation direction of the heating water is determined according to the predetermined data value, the electromagnetic valve 200 installed in the water supply pipe 100 is first cut off and the pressure reduction step of reducing the pressure of the pipe is performed.

This is because, when the water direction controller 600 is rotated when the pressure is high, there is a problem that the heating water leaks or the heated heating water is ejected.

When the pressure reduction step is performed, the water direction controller 600 is rotated in the above-mentioned manner so that the circulation direction of the heating water is changed from the forward circulation to the backward circulation, or from the backward circulation to the forward circulation, .

After the direction of the water channel is changed, the control unit 300 transmits a command to open the shutoff solenoid valve 200 to supply the heating water to the heating zone through the heating water supply step for supplying the heating water.

Further, when the temperature of the heating zone reaches the set temperature value, energy saving effect can be expected through the step of cutting off the heating water by transmitting the command from the controller 300 and shutting off the electromagnetic valve 200.

Particularly, in the case of the central heating, when the electromagnetic valve 200 is closed, the heating water is no longer supplied to the heating zone, and water can be supplied to the next heating zone,

In the case of the single heating system (gas boiler, oil boiler, electric boiler, air heater pump, etc.), the heating water supply of the single heating system is shut off simultaneously with the closing of the solenoid valve 200, Can be saved.
