1 is a schematic configuration diagram of a distributed solar system using inter-generation heat storage according to an embodiment of the present invention.

The distributed solar system using inter-phase heat storage according to the present invention includes a first collector 10 for collecting heat from solar heat; The interlayer heat storage tank 20 connected to exchange the first heat collector 10 and the heat medium; A heat exchanger 30 connected to the heat storage tank 20 and the heat medium to be exchanged; A plurality of loads 40 connected to the heat exchanger 30 to exchange heat medium; And a second collector 50 connected between the plurality of loads 40 and collecting heat from solar heat.

The first collector 10 is a component that raises the temperature by storing the heat medium therein and heating it by solar heat. The heat medium may be water, and other materials may be used instead of water, if necessary. Different materials may be used in combination.

The first collector 10 heats the temperature of the heat medium therein using solar heat and then sends the heat accumulator 20 to the quarterly heat storage tank 20 through a pipe connected to the first collector 10, wherein the pipe connected to the first collector 10 is It may be configured in the form of a heat pipe, and may be configured in a double tube or other form as necessary.

The heat storage tank 20 is a component that is connected to exchange the heat medium with the first heat collector 10, and may be configured to receive heat from the first heat collector 10 and store (heat storage) heat. Quarterly heat storage tank 20 is connected to the first collector 10 and the heat exchanger 30 in a pipe in order to send or receive the heat medium, this pipe may also be configured in the form of a heat pipe, if necessary in the form of a double pipe or other It may be configured.

In addition, a pipe connected to the interlayer storage tank 20 may be equipped with a temperature sensor (not shown) to measure the temperature of the flowing heat medium, a pump for flowing the heat medium may be installed, and a flow meter to measure the flow rate. (Not shown) may be installed.

Referring to FIG. 1, the operation between the first collector 10 and the quarterly heat storage tank 20 will be described briefly. After the heating medium is heated by solar heat in the first collector 10, the first collector 10 and the quarterly heater are described. The heating medium is supplied to the quarterly heat storage tank 20 through the upper pipes installed between the heat storage tanks 20, and the heat medium is recovered to the first heat collector 10 through the lower pipes installed between the first heat collector 10 and the intermittent heat storage tanks 20. By the circulation operation, the temperature of the heating medium may be increased, and heat may be stored in the interlayer storage tank 20.

The heat exchanger 30 is a component that is connected to exchange the heat storage tank 20 and the heat medium, and may be configured to receive the heat medium from the heat storage tank 20 to the load 40 side. That is, the heat exchanger 30 may be connected to the intermittent heat storage tank 20 as a pipe. The pipe may be configured in the form of a heat pipe, and may be configured in a double pipe or another type as necessary. Also, for example, the heat exchanger 30 may be connected to the heat storage tank 20 by two pipes so as to simultaneously exchange heat medium.

The heat exchanger 30 may serve as a condenser or an evaporator in a heat pump cycle or a cooling cycle. For example, the heat exchanger 30 may serve as a condenser when storing heat in the quarterly heat storage tank 20, and may serve as an evaporator when supplying heat to the load 40.

The load 40 is a component connected to exchange the heat exchanger 30 and the heat medium, and may be, for example, various types of buildings or facilities such as educational institutions, public institutions, medical institutions, and residential facilities such as schools. For example, when the distributed solar system using the interlayer heat storage according to the present invention is applied to the university, the load for the heating and hot water supply installed in each building of the university campus can be viewed as a load.

The second collector 50 is a component that is connected between the plurality of loads 40 to collect heat from the solar heat, and stores the heat medium therein to be heated by the solar heat to increase the temperature.

At this time, the supply line 60 for supplying the heat medium to each of the plurality of loads 40 from the heat exchanger 30 may be installed, the return line for returning the heat medium to the heat exchanger 30 from each of the plurality of loads (40) 70 may be installed. The supply line 60 and the return line 70 has a pipe shape, may be configured in the form of a heat pipe, and may be configured in a double pipe or other forms as necessary. In this case, the heat exchanger 30 may supply the heat medium to the load 40 through the supply line 60, and the load 40 may heat the heat medium through the return line 70 to the heat exchanger 30 or the second collector. 50) can be sent to the heating medium.

That is, in the distributed solar system using the interlayer heat storage according to the present invention, the first collector 10 serves as a collector, and the second collector 20 installed on the plurality of loads 40 serves as an auxiliary role. In particular, the heat medium can be efficiently transmitted to the load 40 far from the first collector 10, so that the heating or hot water can be smoothly provided as a distributed solar system.

In addition, the distributed solar system using the inter-generation heat storage according to the present invention may be configured such that the second collector 50 is connected to the supply line (60). At this time, the second collector 50 may be installed so that the heat medium is supplied to the load 40 at a distance away from the inter-generation heat storage tank 20 by a predetermined distance or more. In this case, the predetermined distance is not particularly limited numerically, but may mean a distance such that heat loss may occur when the heat medium supplied from the metered heat storage tank 20 reaches the load 40.

For example, if the load 40 is too far from the quarterly heat storage tank 20, even if the heat transfer from the heat storage tank 20 through the heat exchanger 30 and the supply line 60, the distance is far Heat loss may occur during the transfer of the heat medium and there may be a drop in temperature, thereby allowing the heat medium at a temperature lower than the original temperature to be transferred to the load 40.

However, in the distributed solar system using the interlayer heat storage according to the present invention, the second collector 50 is installed such that the heat medium is supplied to the load 40 at a distance apart from the intermittent heat storage tank 20 by a predetermined distance or more, that is, the interlayer heat storage tank ( The heat medium from the second heat collector 50 is transferred to the load 40 far enough to generate heat loss of the heat medium from the heat medium 20, so that the heat medium can be transferred to the load 40 as if there is no heat loss.

This can be seen as an efficient heat transfer to the load 40 side of the system as a whole. In a configuration in which the second collector 50 is not installed at all, in order to properly transfer heat to the load 40 far enough to generate heat loss of the heat medium from the quarterly heat storage tank 20, a temperature higher than the expected heat loss may be used. The heat medium must be delivered, which may not be possible depending on the performance of the first heat collector 10 and the quarterly heat storage tank 20, and the efficiency of the heat medium must be increased. However, in the present invention, since the second collector 50 is formed on the load 40 side, efficient heat transfer from the second collector 50 to the load 40 side becomes possible.

In addition, the distributed solar system using the inter-generation heat storage according to the present invention may be configured such that the second collector 50 is connected to the return line (70). In particular, when there is an idle site on which the second collector 50 may be installed, it may be easy to install the second collector 50 and the return line 70 on the idle site.

In addition, the distributed solar system using the inter-generation heat storage according to the present invention may be configured to move the heat medium of the return line 70 to the supply line 60 after heat exchange with the second collector (50).

In addition, the distributed solar system using the inter-generation heat storage according to the present invention may further comprise a second heat exchanger (not shown) connected between the second collector 50 and the load. At this time, the second collector 50 opens the valve on the side of the heat exchanger 30 when the temperature of the heat medium in the inside is higher than the temperature of the load 40, that is, the temperature of the heat medium in the supply line 60 connected to the load. Heat medium can be supplied to the load 40, and the second collector 50 has a heat exchanger when the temperature of the heat medium in the heat collector is higher than the temperature of the load 40, that is, the heat medium temperature in the supply line 60 connected to the load. Supply of the heat medium can be stopped by closing the valve on the side of the machine 30.
