Problems solved by technology

The former has a very low thermal efficiency of only about 35% due to the serious loss of heat dissipation on the top surface. Later, the "honeycomb" is used to forcibly suppress the heat dissipation at the top, and the highest efficiency is only 50%.
The latter uses "vacuum" to forcefully suppress heat dissipation at the top, and the thermal efficiency has increased to 58%, which is still very limited
Moreover, because the vacuum technology is extremely complicated and difficult, the cost has increased sharply: the current market sales price has reached 5000-6000 yuan / set
Most people can't afford it

Embodiment 1

[0075] Example 1: Household window type multiple greenhouse solar water heating system

[0076] When designing the system, the following characteristics were first considered: the hot water required by each family can be divided into two categories: one is "low temperature hot water", which is mainly used for bathing, washing, face and feet. The other is boiled water or "hot water", which can also be collectively referred to as "kitchen water", used for direct drinking, cooking, etc.

[0077] The requirements for the water quality and temperature of low-temperature hot water are not high. The water temperature is about 40℃, and the water tank is made of cheap galvanized iron plate. The cost of this kind of hot water is relatively low, but the amount required is large, and the water tank capacity needs 80-150 kg.

[0078] Boiled water or high-temperature hot water has higher requirements for water quality and must meet drinking hygiene standards. Therefore, the water tank must be m...

Embodiment 2

[0083] Example 2: Office window type multiple greenhouse solar water heating system

[0084] The boiling water system in the first embodiment is also suitable for installation on windows with sunlight in the office. Since offices generally do not have low-wall balconies, but only have windows with a wall height of about 1.2m, they are only suitable for installing multiple greenhouses as shown in Figure 2 and Figure 5 (not connected to the room and separated by walls). The boiling water tank (8) is fixed on the window sill, and the heat collector connected with it is still obliquely placed in the multiple greenhouse at the lower end of the window. The size and number of the heat collector are determined by the boiling water demand of the office staff.

[0085] In particular, the hose (12) of the solar heat collector can be connected to a usual electric heating water dispenser-an organic combination, which can save a lot of electricity and make drinking boiled water more convenient....

Embodiment 3

[0087] Example 3: Solar water heaters with multiple greenhouses on the roof

[0088] It can also be used in the same way as the existing vacuum tube solar water heater: place multiple greenhouses on the roof of the building and fix them firmly, with the transparent light-receiving top surface facing the south. At this time, the greenhouse must be fully enclosed, and the heat collector and the water tank (9) are also put into the greenhouse together, and the water tank (9) is located at the upper end of the inclined heat collector and communicates with the heat collector. The inlet and outlet pipes of the water tank (9) pass through the greenhouse and extend along the roof into the room below to the water supply.

[0089] Compared with the existing vacuum tube solar water heater, this embodiment still has the beneficial effects of high thermal efficiency and low cost.

Abstract

A kind of new multiple greenhouse solar energy utilized installment makes the multiple greenhouse installed on the wall of the lower end of outside of window of the building or the none widow wall and the received light face of the installment is consisted of the multiple-layer clarity board or transparency film. The solar energy collector lies in this greenhouse and connects with the hot water tank in the indoor or balcony by the flexible pipe. The collector also can be used as the air collector with the metal board installing in it and connects the thermal converter in the water tank by the utilidor and the gas pump so this conforms to the new hot air source pump. After the water in collector is heated by the sun the hot water tank's water is heated or boiled by the convection. The experiment approves that: the multiple greenhouses and the hot air source pump may improve the environment temperature and reduce the cost largely and improve the thermal efficiency of collector to 90% above also in the aspects of thermal performance, installment and maintenance, use and so on it is privilege to the vacuum solar water heater. Also it can assemble in large area on the top of roof and field in order to implement the cosmically and cheapness and collectivize use.

Description

Technical field [0001] The invention is a new type of solar thermal utilization device. Background technique [0002] There are two main types of existing solar thermal utilization technologies: flat plate and vacuum tube solar water heaters. The former has a very low thermal efficiency due to severe heat loss on the top surface, only about 35%. Later, "honeycombs" were used to forcefully suppress the top heat dissipation, and the highest efficiency was only 50%. The latter uses "vacuum" to forcibly suppress the top heat dissipation, and the thermal efficiency has been improved to 58%, which is still very limited. Moreover, due to the extremely complex and difficult vacuum technology, the cost has increased sharply: the current market price has reached 5000---6000 yuan per unit. Most people can't bear it at all. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing flat panel solar water heater, the present invention further impr...
