Description

Open heating and hot water supply system using solar heat {A Solar Heating Device}

The conventional heating and hot water supply system that is generally used is that the water heater using solar heat and the heater using a boiler such as electricity or gas have a system configuration independent of each other.

However, solar-only water heaters do not use any fuel and emit no exhaust gas for heating the room and receiving hot water, thus providing a significant function to save the environment and to protect the environment. However, the change in calories that can be provided by solar heat is limited, and it is effective only in small houses or small spaces in terms of heating efficiency. In facilities that require large capacity, the purpose of simple hot water supply is only water heater. There was a problem that could only be used.

In addition, the boiler as a heater using a fuel such as electricity or gas is provided with a heat source by burning the fuel, and the excessive heating cost is expended, which not only imposes a considerable economic burden on users, but also emits exhaust gas during fuel combustion. Not only environmental pollution, but also cause serious problems in the human body.

In order to solve the above problems, in recent years, solar water heaters and boilers which integrate solar water heaters and boiler heaters are connected to each other to reduce the fuel cost of the boiler and further reduce the combustion gas discharged during fuel combustion. The invention is disclosed a lot of heating water heater using the invention.

As shown in FIG. 4, the hot water heater 50 using the conventional solar heat and the boiler is

The collector 51 which heats and circulates the heat medium liquid by collecting solar heat, the heat storage tank 52 which heats water introduced by the heat medium liquid heated by the heat collector 51, and the heat medium liquid smoothly. Nitrogen tank (53) for supplying nitrogen to be circulated, and the pressure tank (54) and pressure pump (55) for replenishing the heat medium of the collector 51, the heat medium liquid to the collector 51 A fluid pressure pump 56 for forced circulation in the inside, a ventilation cooling device 57 for cooling the heat medium liquid when it is overheated, and a source of water for use in a hot water supply unit 58 or a heating unit 59. It consists of the boiler 60 to supply.

Here, the heat medium liquid may use a fluid such as an antifreeze liquid.

The heating water heater 50 using the conventional solar heat and the boiler configured as described above is the raw water provided in the heat storage tank 52 while the heat medium liquid heated by the heat collector 51 circulates into the heat storage tank 52. (Water) is warmed, and then the thermal fluid obtained by heat transfer in the heat storage tank 52 is cooled and enters the heat collector 51. At this time, the heat collector 51 circulates while the heat medium fluid becomes hot and the heat medium fluid becomes hot convection, or by forcedly circulating the heat medium fluid using the fluid pressure pump 56, the heat transfer cycle is repeatedly formed in a closed state. To be done.

As the heat transfer cycle is repeatedly performed as described above, when the pressure of the fluid contained in the heat medium liquid decreases, the heat medium in the filling tank 54 may be replenished using the pressure pump 55.

In addition, if the temperature of the heat medium liquid circulating the collector 51 is excessively high when the temperature of the outside air is high, such as in summer, the heat medium liquid is bypassed to the vent cooling device 57 to cool it. To this end, a temperature sensor and a three-way valve may be provided to operate.

Thus, the heat transfer is made in the heat storage tank 52, the raw water (water) that is primarily heated by the solar heat is supplied to the boiler 60 and is heated as a secondary in this place to be utilized as the heating unit 59 or hot water supply It is supplied to the unit 58 to be used.

As the heating hot water supply cycle is made, the boiler heats the raw water heated primarily by solar heat so that the boiler can be operated with less fuel, which saves heating costs and emits less combustion gases. Can be reduced.

Another conventional heating water heater using solar heat and boilers include 'solar heating system' of Patent No. 10-0245532 and 'subsidiary heating device of solar hot water heating system' of Registered Utility Model No. 20-0165569,

The 'solar heating system' of the Patent No. 10-0245532 is configured to circulate the heating water filled in the heating pipe by the circulation pump of the boiler to the circulation outlet through the heat exchanger through the circulation connector as a specific means of the solar heating system, In the solar water heater, the hot water in the heat exchanger is configured to be circulated to the hot water line through the choke valve and the water supply line by a circulation pump, and to be circulated to the hot water line through the choke valve. It is configured to be discharged, and the cold water of the water inlet is configured to flow into the solar water heater through the choke valve.

The 'utility heating device of solar hot water heating system' of the registered utility model No. 20-0165569, pipes a hot water circulation pipe between the solar water heater and the boiler and connects them with conduits to select or simultaneously heat and hot water with solar hot water or boiler hot water. In the solar hot water heating system used, a heat storage tank is installed on the pipeline between the solar water heater and the hot water circulating pipe to warm the solar water heater and store the remaining hot water. The main feature is the auxiliary heating system, which is configured to be useful when temporary heating is needed.

However, the conventional heating water heater 50 as described above is provided with a nitrogen tank, a filling tank, a pressure pump, and a ventilation cooling device that cools the liquid when the heat medium is overheated, which is configured to circulate the heat medium into the collector. As a result, the configuration is complicated, which leads to high cost and complexity of the system.

In addition, there is no specific reference to the configuration and performance of the collector in the 'solar heating system' of the registered patent No. 10-0245532 and the 'secondary heating device of the solar hot water heating system' of the registered utility model No. 20-0165569. There is a problem that no effect can be obtained.

Accordingly, the present invention has been made to solve the above problems, the diameter of the outlet tube of the heat medium liquid than the diameter of the inlet pipe of the heat medium liquid so that the natural fluid is effectively circulated in the heat collector heat medium liquid heated by solar heat It is formed to have a small size to increase the circulation rate of the heated heating medium liquid due to the difference in diameter and at the same time increase the unit area of the heat collecting plate that absorbs solar heat inside the vacuum tube to increase the heat collection efficiency, while preventing the heating medium liquid from overheating It consists of an open tank with a check valve in one direction so that it can simplify the heat transfer cycle between the solar collector and the heat storage tank, minimizing the cost and reducing the cost of failure. Solar heat, which is dramatically improved to double the utility To provide an open, with heating and hot water supply, it is an object.

In the present invention for achieving the above object in the heating hot water supply device using a collector using a solar heat and a boiler using electricity or gas fuel,

The heating hot water supply device includes a heat collector that collects solar heat and heat-circulates the heat medium liquid, and a heat storage tank connected to the heat collector so that water can be warmed due to heat transfer by circulation of the heat medium liquid heated in the heat collector. Is installed in communication with the heat storage tank is provided with an open tank for smoothly circulating the heat medium liquid heated in the collector, and is provided at the inlet side of the open tank 130 is cooled while the heat transfer in the heat storage tank A first check valve for allowing heat medium liquid to flow into the open tank, and a heat medium liquid provided at an outlet side of the open tank and introduced into the open tank so as to circulate and supply the heat medium liquid to the collector And a hot water supply part or egg connected to the circulation pump to heat the raw water (water) installed and connected to the heat storage tank. It consists of the boiler for supplying a portion of a Where Used like is characterized in that is made.

Therefore, the open type heating and hot water supply device using the solar heat of the present invention is simplified by the heat transfer cycle between the heat collector and the heat storage tank using the solar heat while minimizing the cost, as well as cost reduction and breakdown, the durability is dramatically improved. Its efficiency is doubled, and the diameter of the outflow pipe of the heating medium liquid is formed smaller than the diameter of the inflow pipe of the heating medium liquid so that the heating of the heating medium by the solar heat can be effected naturally in the collector. The circulation rate of the heat medium liquid is increased and the heat efficiency is significantly improved by increasing the heat collecting efficiency by increasing the unit area of the heat collecting plate that absorbs solar heat inside the vacuum tube.

In addition, the heating hot water supply cycle using solar heat is carried out so that the boiler heats the raw water heated primarily by solar heat so that the boiler can be operated with less fuel, thus saving heating costs and less combustion gas. It can also reduce the environmental pollution.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Open heating and hot water supply device 100 using the solar of the present invention, as shown in Figures 1 to 3,

A collector (110) for collecting heat of the sun and heating and circulating the heat medium liquid;

A heat storage tank 120 connected to the collector 110 so that water is heated by heat transfer by the circulation of the heat medium liquid heated in the collector 110;

An open tank 130 communicating with the heat storage tank 120 to allow the heat medium liquid heated in the heat collector 110 to be circulated smoothly;

The first check valve 140 is provided at the inlet side of the open tank 130 to allow the heat transfer liquid to flow into the open tank 130 while the heat is transferred in the heat storage tank 120. )Wow,

A circulation pump 150 provided at an outlet side of the open tank 130 and configured to circulate and supply the heat medium liquid introduced into the open tank 130 to the collector 110;

The boiler 180 is connected to the heat storage tank 120 and is heated to supply raw water (water) to be supplied to the hot water supply unit 160 or the heating unit 170.

In addition, a second check valve 190 is installed at the outlet side of the circulation pump 150 to control the heat medium liquid to flow toward the collector 110.

In addition, the collector 110 for collecting solar energy is installed in spaced from the inlet pipe 111 and the inlet pipe 111 to circulate the heat medium fluid as shown in Figures 2 and 3, While the heat medium fluid is heated by solar heat to circulate and supply the heat storage tank 120, the inlet pipe 111 and the inlet pipe 111 and the outlet pipe 112 is installed therein and installed in the inlet pipe Insulating cover that is fixed to one side of the vacuum tube 115, which is installed in each of the first branch pipe 113 and the second branch pipe 114 is branched from the outlet pipe 112 is branched in communication (111) ( 116).

Here, the diameter of the first branch pipe 113 branched from the inlet pipe 111 is larger than the diameter of the second branch pipe 114 branched from the outlet pipe 112. That is, the diameter of the second branch pipe 114 is configured to be formed smaller than the diameter of the first branch pipe 113.

As described above, the diameter of the second branch pipe 114 is formed to be smaller than the diameter of the first branch pipe 113 so that the heat medium liquid introduced into the first branch pipe 113 is transferred to the second branch pipe 114. Heated more at the same time than the heat medium liquid flowing into the) and the flow rate is faster due to the difference in diameter, which causes a rapid circulation of the heat medium liquid in the collector.

In addition, the vacuum tube 115 has a structure in which a heat absorbing plate 117 is inserted along the longitudinal direction from the inner wall surface to surround the first and second branch pipes 113 and 114 to collect solar heat. .

Here, the heat absorbing plate 117 is provided in a gear shape so as to have more heat absorbing areas in the same space, that is, to increase the heat absorbing area per unit area subjected to solar heat (sections A-A 'and BB'). Reference)

In addition, the collector 110 may be installed by spirally winding the second branch pipe 114 to the first branch pipe 113. In addition, the length of the first branch pipe 113 longer than the length of the second branch pipe 114 is provided so that the heat medium fluid circulated to the second branch pipe receives more solar energy, the first branch pipe The temperature of the heat medium liquid in the second branch pipe is higher than that of the heat medium liquid in the cell so that the circulation of the heat medium liquid due to the temperature difference is made faster (see FIG. 3).

Therefore, when the heat medium fluid flowing into the first branch pipe 113 passes through the second branch pipe 114, the passage time is increased to increase the temperature at which the heat medium liquid receives more solar heat and heats up, thereby improving thermal efficiency. It becomes possible.

Open heating and hot water supply device 100 using the solar heat of the present invention configured as described above is the heat medium in the heat collector 110 through the first branch pipe 113 through the inlet pipe 111 to generate solar heat It is gradually heated, and then the heat medium liquid is heated to a higher temperature while passing through the second branch pipe (114) to flow through the heat storage tank (120) through the outlet pipe (112).

At this time, the heat of the high temperature held by the heat medium liquid while passing through the heat storage tank 120 is gradually cooled as heat is transferred to the water stored in the heat storage tank 120.

In this process, the heat medium liquid is cooled and the water stored in the heat storage tank 120 is heated.

The cooled heat medium liquid is introduced into the open tank 130 through the first check valve 140. At this time, the overheated heat medium liquid is circulated more rapidly to be cooled, thereby preventing the heat medium from being overheated.

The heat medium liquid introduced into the open tank 130 is circulated to the inlet pipe 111 installed in the collector 110 through the circulation pump 150 and the second check valve 190, and a series of heat transfer cycles. This is done.

As the heat transfer cycle is performed, solar energy heats the water in the heat storage tank 120. Then, the heated water in the heat storage tank 120 is supplied to the boiler 180 again to supply the boiler 180. In addition, it is heated to be supplied to the hot water supply unit 160 or the heating unit 170 desired by the user can be used.

In this way, by supplying the water heated primarily by the solar energy in the heat storage tank 120 to the boiler 180, the three-way valve in the boiler 180 as much as the heat energy transferred from the heat storage tank 120. By controlling this, energy can be saved, thus saving fuel consumption, and thus, heating costs can be saved, and less combustion gas is emitted to reduce environmental pollution, thereby providing an eco-friendly heating hot water supply system.

This is because when the heat medium is expanded (high heat) due to the heat change, the check valve 140 is opened and the heat medium is discharged. On the contrary, when the heat medium is contracted (low heat) due to the heat change, the check valve 190 is opened and the check valve 140 is opened. Due to the closed interlocking action, natural and forced circulation work together to maximize the effect of energy saving.
