Description

The solar energy heating apparatus in which the heat exchange facilitates}

The present invention relates to a solar heating device that facilitates heat exchange. More specifically, it relates to a heat exchanger with a new structure that heats heating water using a boiler in addition to solar heat, has high efficiency through a heat exchanger, and can prevent freezing and bursting of solar thermal collectors. It's about this easy solar heating device.

In general, a solar heating device designed to provide heating by heating water using solar energy heats the water using a solar collector, stores the heated water in a hot water tank, and then stores the water stored in the hot water tank. It is configured to provide heating by circulating heating water through heating pipes.

However, since these solar heating devices heat the heating water using solar heat, there are cases where the heating water cannot be heated sufficiently depending on the temperature or weather.

Therefore, in order to solve this problem, a method of connecting a boiler to the hot water tank to heat the heating water stored in the hot water tank is used. However, this solar heating device has low efficiency, and when the temperature falls below freezing, the solar collector There was a case where the heating water stored in the unit froze and the solar panel froze.

Accordingly, in order to solve this problem, as shown in Patent No. 10-1801490, “Heating device using solar heat as an auxiliary heat source” pre-registered by the applicant, “Heating auxiliary water heated in the solar heat collection device 10 is used for solar heat collection.” It passes through the heat supply pipe (14a) of the heat exchanger (14) connected to and mounted on the other end of the solar power supply pipe (11) connected to one side of the device (10) to the solar pump (13) formed in the solar heat recovery pipe (12). a solar heating circuit (1) that allows the solar heat to flow back into the solar heat collection device (10) through the solar heat recovery pipe (12);

The heating space (C) is heated by heating water heated in the boiler (20) by the heating means (50) connected to one side of the boiler (20) through the boiler supply pipe (21) to the other side, and then through the boiler return pipe. The heating water discharged to (22) is connected to the boiler return pipe (22) through the boiler pump (23) mounted on the boiler return pipe (22) and passes through the heat radiation pipe (14b) of the heat exchanger (14) mounted on the boiler return pipe (22). A boiler heating circuit (2) that flows back into (20);

The hot water pump (33) mounted on the hot water supply pipe (32) passes hot water heated by solar power generated in the solar hot water storage device (30) through the hot water inlet pipe (31) and the hot water pipe (25) of the boiler (20). It is configured to include a hot water supply circuit (3) that allows new water to be discharged to the hot water supply pipe (32) through the solar hot water storage device (30) through the water supply pipe (34) connected to the water supply pipe (40). As can be seen from “A heating device that uses solar energy as an auxiliary heat source,”

By allowing the heat source of solar heat and the heat source of the boiler to be used sequentially, the heat source required for heating can be supplied to the heating space sequentially without any manipulation depending on weather conditions, so that solar heat can be used without any manipulation according to the set temperature of heating according to weather conditions. The heat source can be used as a heat source for heating, thereby increasing the efficiency of solar energy and reducing the energy required for heating. In addition, it can mechanically and safely prevent overheating of heating water generated from solar heating plates in the summer. In addition, it is simple to operate to quickly supply hot water when needed in the winter, has low installation and maintenance costs, and has a very remarkable effect of high thermal efficiency, so anyone can use the solar heat of the present invention as an auxiliary heat source without much burden. The heating equipment used was made easy to install and use in each home.

However, although the above configuration and operation can achieve a certain level of effectiveness, it is practically difficult to heat heating water and hot water separately as needed using a boiler in addition to solar heat, and it is difficult to control the external temperature divided into winter and summer. Due to the difficulty in converting the heating water and hot water using a heat exchanger, it is difficult to control the temperature of the hot water or heating water to match the external temperature that changes according to temperature changes, so it is not easy to use a practical heating device, but it is possible to install a solar heating device. Neither the equipment companies nor the management companies that sell and manage them are able to come up with a solution to this problem.

Therefore, a new method to solve these problems has become necessary.

Since the solar heat collecting plate (A) has been developed and used in various forms, further detailed description thereof will be omitted.

The water supply pipe 21 and the drain pipe 22 are provided with manual valves 21a and 22a that can be manually operated by the user.

The heat exchanger 23 has one end connected to the third supply part 11c and the other end connected to the front of the area where the bypass pipe 19 is connected in the first return part 12a, and is connected to the third supply part 11c. By allowing heat exchange between the hot heating water supplied through (11c) and the lukewarm heating water that passes through the heating pipe (1) and then cooled and then passing through the first return portion (12a), the return pipe (12) or bypass The temperature of the heating water supplied to the solar collector A or the hot water tank 13 through the pipe 19 is increased.

The first temperature sensor 37 is provided in the first supply unit 11a so as to be as close as possible to the solar collector A, and measures the temperature of the heating water passing through the solar collector A. It is configured so that the temperature of the heat collecting plate (A) can be measured together.

The first to ninth electronic control valves 24 to 33 use solenoid valves that are operated under the control of the control means 39 to control the flow of heating water.

The first to third supply pumps 34, 35, and 36 use general water pumps that supply heating water in one direction when operating.

The water supply pipe 21 is connected to a water pipe and is configured to additionally supply water to the hot water tank 13 by opening the manual valve 21a provided in the water supply pipe 21.

The operation of the solar heating device configured in this way for easy heat exchange is explained as follows.

First, in normal times, as shown in FIG. 3, the control means 39 opens the first, fourth, fifth and sixth electronic control valves 24, 27, 28, and 29, and the first and The second supply pumps 34 and 35 are driven so that the heating water heated by the solar collector A is stored in the hot water tank 13.

At this time, the control means 39 is operated when the temperature inside the hot water tank 13 measured by the second temperature sensor 38 rises to 90 degrees or higher, or when the temperature measured by the first temperature sensor 37 increases to 90 degrees or higher. When the temperature becomes lower than the temperature measured by the second temperature sensor 38, the first, fourth, fifth and sixth electronic control valves (24, 27, 28, 29) are closed, and the first and second Stop the supply pumps (34,35).

And, when the temperature measured by the first temperature sensor 37 decreases to 0 degrees, as shown in FIG. 3, the first, fourth, fifth and sixth electronic control valves (24, 27, 28, 29) ) is opened and the first and second supply pumps 34 and 35 are driven to supply the high-temperature heating water stored in the hot water tank 13 to the solar collector A, thereby heating the inside of the solar collector A. It prevents water from freezing and freezing of solar heating devices that facilitate heat exchange.

And, when the user inputs a heating command by manipulating the input means (39a), the control means (39) receives signals from the first and second temperature sensors (37, 38), and the solar collector (A) ), when the temperature of the heating water passing through is 60 degrees or higher, as shown in FIG. 4, the first, second, third and fourth electronic control valves (24, 25, 26, 27) are opened, The first supply pump 34 is driven to allow heating water heated while passing through the solar collector A to pass through the heating pipe 1 to provide heating.

At this time, the temperature of the heating water measured by the first temperature sensor 37 decreases to 60 degrees or less, and the temperature of the heating water stored in the hot water tank 13 measured by the second temperature sensor 38 decreases to 60 degrees. If it is abnormal, the control means 39 opens the first, second, fourth, sixth, and ninth electronic control valves (24, 25, 27, 29, and 33), as shown in FIG. 5, The second supply pump 35 is driven to allow hot water stored in the hot water tank 13 to pass through the solar collector A and the heating pipe 1 and then return to the hot water tank 13 for heating.

And, when the temperature measured by the first and second temperature sensors 37 and 38 falls below 60 degrees, the control means 39 operates the seventh, eighth and second temperature sensors, as shown in FIG. 6. After opening the ninth electronic control valve (31, 32, 33) and driving the third supply pump (36), the heating water heated in the boiler (16) passes through the heating pipe (1), and then the hot water tank (13) ), thereby increasing the temperature of the heating water stored in the hot water tank 13 by circulating it to the boiler 16.

Meanwhile, the user opens the manual valves 21a and 22a provided in the water supply pipe 21 and the drain pipe 22 to discharge and use the warm heating water stored in the hot water tank 13 to the outside or use the hot water tank 13. ), additional water can be supplied.

The solar heating device configured in this way for easy heat exchange heats heating water using a solar collector (A) and stores it in the hot water tank (13), and determines the temperature of the solar collector (A) and the hot water stored in the hot water tank (13). Depending on the temperature, the heating water that has passed through the solar heat collector (A), the heating water stored in the hot water tank (13), or the heating water heated by the boiler (16) is selectively supplied to the heating pipe (1), so efficiency is very high. In addition, when the temperature of the solar collector (A) falls below 0 degrees, the hot water stored in the hot water tank (13) can be circulated to the solar collector (A), preventing the solar collector (A) from freezing. There is an advantage.

In particular, the third supply part 11c and the first return part 12a are connected to each other by a heat exchanger 23, so that hot heating water supplied through the third supply part 11c and the heating pipe 1 After being cooled by passing through, the lukewarm heating water passing through the first return part (12a) exchanges heat with each other, and is transferred to the solar collector (A) or hot water tank (13) through the return pipe (12) or bypass pipe (19). There is an advantage that thermal efficiency is further improved by increasing the temperature of the supplied heating water.

7 to 10 show a second embodiment according to the present invention, wherein the solar heat collecting plate (A) includes a heat collecting case 40 provided with a transparent plate 41 on the upper surface, and a heat collecting case 40 of the heat collecting case 40. A heat collecting pipe 50 provided inside and connected to the supply pipe 11 and the return pipe 12 at both ends, and an auxiliary heat collecting pipe 50 provided on one side of the heat collecting case 40 and equipped with a transparent plate 61 on the upper surface. A case 60, a first cleaning means 70 provided on the upper surface of the heat collecting case 40 to clean the transparent plate 41 of the heat collecting case 40, and a first cleaning means 70 provided on the upper surface of the auxiliary case 60. a second cleaning means (80) for cleaning the transparent plate (61) of the auxiliary case (60), and a third temperature sensor provided inside the heat collecting case (40) to measure the internal temperature of the heat collecting case (40). It consists of (91) and a fourth temperature sensor (92) provided inside the auxiliary case (60) to measure the internal temperature of the auxiliary case (60).

The heat collecting case 40 is configured in a square shape.

The heat collecting pipe 50 is arranged in a zigzag shape in the vertical direction inside the heat collecting case 40, so that the heating water supplied to the supply pipe 11 passes through the inside, and the solar heat collecting case 40 passes through the heat collecting pipe 50. When light is irradiated, the heat collection pipe 50 is heated by the heat of sunlight, so that the heating water passing through the inside is heated and then discharged to the return pipe 12.

The auxiliary case 60 has an area when viewed from above that is very small compared to the area of the heat collecting case 40.

Preferably, the area of the auxiliary case 60 is less than 1/10 of the heat collecting case 40.

The first cleaning means 70 is provided to be in close contact with the upper surface of the transparent plate 41 and is slid laterally by the slide driving means 72 to clean the upper surface of the transparent plate 41. It consists of

The cleaning member 71 is composed of a support bar 71a made of metal and an adhesion member 71b made of elastic rubber, and is arranged so that the adhesion member 71b is in close contact with the upper surface of the transparent plate 41. do.

The slide driving means 72 is provided to extend laterally on the upper surface of the heat collecting case 40 and includes a guide rail 72a to which the cleaning member 71 is slidably coupled, and a heat collecting case extending laterally. It is rotatably provided at (40), and the middle portion includes a lead screw (72b) coupled to laterally penetrate the support bar (71a), and is connected to the lead screw (72b) to rotate the lead screw (72b) forward and backward. It consists of a drive motor (72c).

Accordingly, when the lead screw 72b is rotated by the drive motor 72c, the cleaning member 71 slides laterally, removing foreign substances such as snow or dust accumulated on the upper surface of the transparent plate 41. By pushing and removing, the upper surface of the transparent plate 41 can be cleaned.

The second cleaning means 80 uses a wiper 81 that is provided in close contact with the upper surface of the transparent plate 61 of the auxiliary case 60 and rotated to both sides by a drive motor 82.

Accordingly, when the wiper 81 is rotated to both sides by the drive motor 82, the wiper 81 pushes out and removes foreign substances accumulated on the upper surface of the transparent plate 61 of the auxiliary case 60 in the side direction.

The control means 39 receives signals from the third and fourth temperature sensors 91 and 92 and is configured to control the operation of the first and second cleaning means 80.

The operation of this solar heating device that facilitates heat exchange is explained as follows.

First, the control means 39 periodically operates the second cleaning means 80 to remove foreign substances accumulated on the upper surface of the auxiliary case 60.

In addition, the control means 39 monitors the internal temperature of the heat collection case 40 and the auxiliary case 60 measured by the third and fourth temperature sensors 91 and 92, and controls the temperature of the heat collection case 40. When the internal temperature is lower than the internal temperature of the auxiliary case 60, it is determined that foreign matter has accumulated on the upper surface of the heat collecting case 40, and the first cleaning means 70 is driven to clean the upper surface of the collecting case 40. Remove foreign substances accumulated in the.

That is, the transparent plate 61 of the auxiliary case 60 is periodically cleaned by the second cleaning means 80, so that the transparent plate 61 is maintained in a clean state, and when sunlight is irradiated, the auxiliary case ( 60) The interior is heated by sunlight.

And, when sunlight is irradiated while foreign matter is accumulated on the upper surface of the heat collecting case 40, the sunlight is blocked by the foreign matter, and the temperature inside the heat collecting case 40 is lower than the internal temperature of the auxiliary case 60. You lose.

That is, the fact that the internal temperature of the heat collecting case 40 is lower than the internal temperature of the auxiliary case 60 means that foreign substances have accumulated on the upper surface of the heat collecting case 40. In this case, the control means 39 By driving the first cleaning means 70 to remove foreign substances accumulated on the upper surface of the heat collecting case 40, it is possible to prevent the efficiency of the heat collecting case 40 from being lowered due to foreign substances.

In particular, the size of the heat collecting case 40 is large, so the size of the first cleaning means 70 for cleaning the heat collecting case 40 must also be large, and when the first cleaning means 70 is driven, a lot of electricity is consumed. In addition to consumption, the lifespan of the first cleaning drive means is shortened, thereby increasing maintenance costs.

However, in the present invention, the auxiliary case 60 is periodically cleaned using a small-sized second cleaning means 80, and the internal temperature of the heat collecting case 40 and the auxiliary case 60 are compared to determine the temperature of the heat collecting case 40. ) has the advantage of reducing electricity consumption and maintenance costs by confirming the accumulation of contaminants.
