Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar system having a condenser lens which can be used by heating water in a water supply pipe with solar heat.

[0002]

2. Description of the Related Art A conventional hot water supply solar system collects solar heat on a heat collecting plate, and uses water heated by the heat for hot water supply.

[0003]

However, the temperature of water heated by a conventional hot water supply solar system is generally low and not constant, although there are seasonal differences. For this reason, in the conventional system, the warmed water is usually further heated using a boiler, and is used after being heated to a required temperature. Therefore, in the conventional hot water supply solar system, there is a problem that the cost increases because the boiler is installed and used.

[0004] The present invention has been made in view of such conventional problems, and it is possible to supply high-temperature water without using a boiler, and to reduce the cost required for a boiler. It is intended to provide a solar system equipped with an optical lens.

[0005]

In order to achieve the above object, a solar system having a condensing lens according to the present invention comprises: a main body case having an opening at an upper part; and a water supply provided in the main body case. A pipe, a heat exchanger provided in contact with the upper surface of the water supply pipe in the main body case, a heat collecting plate provided in contact with the upper surface of the heat exchanger in the main body case, And a plurality of condenser lenses disposed above the heat collecting plate and focused on the heat collecting plate, and a transparent lid for opening and closing the opening of the main body case.

The water supply pipe is preferably provided in a meandering manner in the main body case. The heat exchanger is made of, for example, a metal bellows plate. The heat collecting plate preferably has high heat resistance. The condenser lens may be composed of a Fresnel lens or a convex lens. The condenser lens may have a microcomputer-controlled drive mechanism to track the movement of the sun and to always concentrate the sunlight on one point on the heat collecting plate. In this case, the power of the drive mechanism may be the power of a generator described later. The solar system including the condenser lens may be used for a heating system, a cooling system, and a power generation system in addition to the hot water supply system. For example, a portion of the water in the water supply pipe may be introduced into a steam turbine to drive the generator with steam power. In this case, the generator is preferably an outer rotor generator having good power generation efficiency.

In the solar system provided with the condenser lenses according to the present invention, each condenser lens concentrates sunlight on one point on the heat collecting plate and heats the heat collecting plate. The heat of the heat collecting plate is transmitted to the water supply pipe via the heat exchanger, and heats the water in the water supply pipe to a high temperature.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. As shown in FIGS. 1 to 3, a solar system 1 including a condenser lens includes a main body case 2,
It has a water supply pipe 3, a heat exchanger 4, a heat collecting plate 5, a plurality of condenser lenses 6, and a transparent lid 7. As shown in FIG. 3, the solar system 1 provided with a condenser lens is installed on a roof A of a house, for example.

As shown in FIG. 1, the main body case 2 comprises a rectangular parallelepiped box having an opening at an upper part. The water supply pipe 3 is arranged in a meandering manner in the main body case 1. The water supply pipe 3 has a water supply port 3 a connected to a water pipe, and a water discharge port 3 b connected to a steam turbine 8. The heat exchanger 4 is made of a metal bellows as shown in FIG.
Is provided in contact with the upper surface of. The heat collecting plate 5 is made of a metal plate having high heat resistance, and is provided in contact with the upper surface of the heat exchanger 4 in the main body case 1. The plurality of condenser lenses 6 each have a diameter of about 30 cm, are disposed above the heat collecting plate 5 in the main body case 1 and are focused on the heat collecting plate 5. As shown in FIG. 2, the angle of each condenser lens 6 can be adjusted according to the incident angle of the sun. The condenser lens 6 may track the movement of the sun by a drive mechanism controlled by a microcomputer. The transparent lid 7 opens and closes the opening of the main body case 1 to prevent dust from entering the main body case 1.

[0010] The steam turbine 8 rotates the turbine by the power of steam generated from the water supply pipe 3. The turbine drives the generator 9. The generator 9 is composed of an outer rotor generator (manufactured by Shin Nippon Giken Co., Ltd.) having extremely small acceleration torque and good power generation efficiency. Generator 9
Is supplied to the home through the wiring 9a and can be used for lighting, television, refrigerator, washing machine, cooler, electric heater and the like. The steam used to drive the steam turbine 8 is returned to high-temperature hot water and returned to the hot water supply pipe 8.
It is discharged from a and used at home for hot water supply, bathing, and others.

Next, the operation will be described. In the solar system 1 provided with a condenser lens, each condenser lens 6 concentrates sunlight on one point on the heat collecting plate 5 and the heat collecting plate 5
Heat to a high temperature of ~ 600 <0> C. The heat of the heat collecting plate 5 is efficiently dispersed by the bellows-like heat exchanger 4 and conducted to the water supply pipe 3, and the water in the water supply pipe 3 is heated to high-temperature steam. This steam drives the steam turbine 8 to cause the generator 9 to generate power. The steam used for power generation is returned to high-temperature hot water by natural cooling and used at home. It is preferable that high-temperature hot water is stored and used in a heat retention tank. Condensing lens 6
In a conventional hot water supply solar system that does not use water, there is a limit to the heating temperature of water, and the temperature can only be increased to about 82 to 83 ° C. However, according to the solar system 1 equipped with a condenser lens, The water in the pipe 3 can be turned into high-temperature steam of 100 ° C. or higher. Thus, high-temperature hot water can be supplied without using a boiler, so that the cost required for the boiler can be reduced and energy can be saved.
The solar system 1 equipped with a condenser lens can be used not only for home use but also for large facilities such as sports centers and shopping centers and factories.

A solar system 1 having a condenser lens
Is useful for global environmental protection because it uses only natural energy using sunlight and does not use combustion energy from boilers. The solar system 1 equipped with a condenser lens is installed in a facility that requires hot water supply, electricity, heating, cooling, etc., and receives all energy necessary for the facility only from sunlight without receiving external energy supply. It is very useful industrially.
