Abstract

PURPOSE:To permit a high-temperature heat collection as well as a low-temperature heat collection at the same time by a method wherein two sets of heat collecting plates are provided at the locations where solar beams in morning and afternoon are collected by a linear lens while heat mediums, heated by respective heat collecting plates, are reserved in a high-temperature and a low-temperature heat reserving tanks. CONSTITUTION:In the device which is heating a heat collecting member by the solar beams passed through the linear lens 1, the heat collecting member, consisting of first heat collecting plate 21 and second heat collecting plate 22, intercepted thermally, is arranged at a position where the solar beams, comming from different positions in the morning and the afternoon, are collected by the linear lens 1. The heat mediums, heated by each heat collecting plates, are reserved into the high-temperature heat reserving tank 5H and the low-temperature heat reserving tank 5L through different circulating paths while the heat mediums are reserved into the tank 5H in case the heat collecting condition of the heat collecting plate is a high temperature but are reserved into the low-temperature heat reserving tank 5L when the same is a low temperature, and each operations are effected by switching the circulating paths. As a result, the high-temperature heat collection as well as the low-temperature heat collection may be effeced at the same time and the device may be utilized for the purposes of a wide range.

Description

[Detailed Description of the Invention] The present invention provides a solar heat collection device that enables high-temperature heat collection and low-temperature heat collection and has a wide range of uses.Since the main use of solar energy is for general household use, it is for hot water heating. 90
Low-temperature heat collection below °C is sufficient, but for industrial use it is 100 to 2
It becomes necessary to collect heat at temperatures as high as 00°C.

Conventionally, emitted heat collection and high-temperature heat collection were performed using a dedicated heat collector. However, even for industrial use, low-temperature heat collection is required for hot water supply, and even for domestic use, when an absorption refrigerator is used for cooling, high-a heat collection is required.

Conventionally, it would be necessary to install a heating device for both sides),
Er"l also had problems with the installation work. In view of this, the present invention provides a heat collecting plate that is heated by sunlight using a linear lens, and a heat collecting plate that is heated by 7JI by diffused light. This configuration allows the collection of heat from high to low temperatures (2), and the configuration 7 is a system in which the heat collection member is made to heat up to the temperature of the jaw by sunlight passing through a linear lens. The thermal member is arranged at a position where sunlight from different positions in the morning and afternoon is focused by a linear lens, and is composed of a first heat collecting plate and a second heat collecting plate which are separated by heat. 1. The heat medium heated in the second heat transfer plate is stored in a high temperature heat storage tank and a low temperature heat storage tank C in separate circulation paths. This is a solar heat collecting device characterized by having an f2 configuration in which storage is switched between a tank and a low-temperature heat storage tank when the temperature is low.

Therefore, high-temperature heat collection and low-temperature heat collection occur at the same time, and due to the movement of the sun, what used to be high-temperature heat collection switches to low-temperature normal heat, thereby changing the stored light of the heat medium. Tracking heat collecting plates and lenses 8! ◎ An example will be explained below with reference to figures. (1) is a linear lens such as a Funnel lens or a kamaboko lens.

When the sun is shining, it is placed in the position where the sunlight concentrated by the linear lens ([) is irradiated, and conversely, the second heating plate is placed in the position where the sun is from the upper level until sunset. In this case, the position where the concentrated sunlight is irradiated +
