Description

Solar heating and cooling devices

technical field

The utility model relates to a solar heating and cooling device.

Background technique

At present, under the situation of world energy shortage and soaring prices of various energy sources, all countries have turned their attention to renewable energy. Firstly, this kind of energy is renewable, inexhaustible and inexhaustible; secondly, renewable energy Environmentally friendly, the harm to the earth and human living environment is almost negligible. Among renewable energy sources, solar energy is undoubtedly the most eye-catching. In the field of solar energy utilization, solar photovoltaic cells, solar water heaters and other products have been popularized within a certain range. Solar lighting products and solar buildings are also being tried and promoted. Air-conditioning technology has also developed to a certain extent.

In summer, the power consumption of air conditioners is almost one-third of the power consumption of the entire power system, which is one of the reasons why the power system is overwhelmed in summer. Therefore, solar air conditioners have great temptation from the beginning.

At present, there are many kinds of solar air-conditioning technologies, mainly absorption refrigeration and photoelectric conversion of electric energy to drive refrigeration. In actual application, people's needs are not completely consistent with the energy provided by solar energy: when the solar radiation is stronger and the weather is hotter, the load on our air conditioners is also greater; when the weather is colder and people need warmth more, The supply of solar energy is often insufficient. Therefore, these systems all have low refrigeration efficiency and high cost, which seriously affects the promotion and application of solar refrigeration systems.

Utility model content

The purpose of the utility model is to provide a low-cost, high-efficiency solar heating and cooling device.

In order to achieve the above purpose, the utility model adopts the following technical scheme: solar heating and cooling devices, including solar heat absorbing panels arranged on the sunny side of the house, the outer surface of the house is provided with a heat insulation material layer, and the solar heat absorbing There is a sealed air channel between the board and the heat insulation material layer, and a pump body connected to the sealed air channel can be used to draw air in one direction outside, and a pump body connected to the sealed air channel can be used to draw air in one direction on the upper part of the room. The lower part of the chamber is provided with a pipeline communicating with the sealed air channel and a channel with a switch communicating with the outdoor cool air source.

The solar heat absorbing board is a wavy curved board.

A mesh partition is arranged in the channel connected to the outdoor cool air source provided at the lower part of the room.

The utility model can realize forced heating and cooling, has low cost and high efficiency, and is integrated with buildings to be more beautiful, fully utilizes renewable energy, reduces environmental pollution, and improves people's living environment. The solar heat absorbing panel is a wavy curved panel, which can increase the sunlight absorption surface and fully heat the air between the solar heat absorbing plate and the heat insulation material layer. The channel connected to the outdoor cool air source provided at the lower part of the room is provided with a mesh partition, which can prevent rats and insects from entering the room.

Detailed ways

As shown in Figure 1: the solar heating and cooling device includes a solar heat absorbing plate 1 arranged on the sunny side of the house, and the outer surface of the house is provided with a heat insulating material layer 6, and the solar heat absorbing plate 1 and the heat insulating material layer There is a sealed air channel between the 6, and a pump body 3 that communicates with the sealed air channel can be unidirectionally drawn outside. The upper part of the room is provided with a pipeline 4 that communicates with the sealed air channel. The pump body 5 that draws air inwardly, the indoor lower part is provided with the pipeline 8 that communicates with the sealed air channel, and the channel 10 with the switch that communicates with the outdoor cool air source. The channel 10 can be connected with the shade of the building or a deep well, and a mesh partition 9 is arranged in the channel 10 .

The outside of the body of wall 7 of the building is equipped with a thermal insulation material layer 6, and the solar heat absorbing plate 1 with a geometric shape is fixed on the sunny wall of the building and the top of the slope layer of the house is attached to the thermal insulation material layer 6. The hot plate 1 is a wavy curved panel, as shown in Figures 2 and 3.

The utility model and the building form an integrated forced heating and cooling system. The outer layer of the building adopts the heat insulation material layer 6 for heat insulation and insulation protection. The solar heat absorbing plate 1 adopts a scientific geometric shape (see Fig. Air intake holes are arranged on special parts of the heat-absorbing plate, which effectively accelerates the rising speed of hot air.

The operation process of the solar forced cooling function is as follows: after the solar heat absorbing plate 1 absorbs heat, the airflow inside it rises rapidly to form a vacuum, which is compensated by the air in the room, and there is a cool air channel 10 in the room that communicates with the outside. The channel 10 of cool air can lead to the shady part of the building or deep well, so the air in the whole room is circulated. After the outdoor pump body 3 is connected to the solar heat absorbing plate 1 through the channel 2, the gas heated by the solar heat absorbing plate 1 is discharged outside while accelerating the rising speed of the heated gas, so as to achieve the purpose of forced cooling. On the passage 10 leading to the cool air in the room, a mesh partition 9 is installed to prevent rats and insects from entering the room.

The operation process of the solar forced heating function is as follows: after the solar heat absorbing plate 1 absorbs heat, the airflow inside it rises rapidly to form a vacuum, which is compensated by the air in the room, thereby realizing (internal) circulation. After the indoor pump body 5 is connected to the solar heat absorbing plate 1 through the channel 4, the gas heated by the solar heat absorbing plate 1 is discharged into the room, and the rising speed of the heated gas is accelerated, thereby realizing the forced temperature increase in the room and drying Effect. The passage 2 leading to the outside and the cool air passage 10 leading to the room are closed.
