Description

A binary solar panel

technical field

The utility model relates to the technical field of comprehensive application devices of natural energy, in particular to a binary solar polymer panel which comprehensively utilizes solar energy and air heat energy.

Background technique

As important renewable clean energy, solar energy and air energy have been paid more and more attention to their development and application. At present, the application of solar energy is mainly in two aspects of power generation and heat supply; solar water heaters, especially vacuum tube solar water heaters, have developed relatively mature technology and have been industrialized on a large scale, but the biggest shortcoming of solar water heaters is that they must be heated in the presence of sunlight. It can be used better during the day. Use the heat energy in the air to develop air-energy water heaters. Some domestic companies such as Midea, Haier, and Gree have competed to develop and produce household air-energy water heaters and have put them on the market. The advantage of air-energy water heaters is that they have a higher energy efficiency ratio and consume 1kW. Electricity, under the energy efficiency ratio of grade I, can generate heat energy of at least 4kW or more, but the heat generation coefficient of air-energy water heaters developed solely on air energy is limited, and the application is limited when the ambient temperature is low. In addition, the current air energy Water heater installations take up a lot of space and are expensive.

Due to the respective defects of solar water heaters and air energy water heaters, the development of application devices such as water heaters that can comprehensively apply solar energy and air energy has aroused great interest in people. For example, the Chinese patent document whose application publication number is CN102393079A discloses an integrated energy supply system that comprehensively utilizes solar energy and air energy, which uses solar energy to generate electricity with semiconductor temperature difference, and utilizes the Peltier effect to generate heat; another example is the authorized announcement number CN202267229U The Chinese patent document of , which discloses an air source and solar energy integrated machine; it utilizes solar energy through a vacuum heat pipe, but only mentions that there is an air source device that utilizes air energy, but the air source device has no specific structure and Embodiment; Another example is the Chinese patent document whose authorized announcement number is CN203719142U, which discloses a solar air energy integrated hot water system, which adopts 2 water tanks, does not specify the specific way of heat collection, and the work of the air source heat pump group Way.

It can be seen that the core of the difficulty in developing an application device such as a water heater that can comprehensively apply solar energy and air energy is to develop an integrated heat exchange device that can effectively convert solar energy and air energy into heat energy.

(Application example)

Referring to Fig. 4 and Fig. 5, the binary solar energy aggregate plate of the foregoing embodiment, when in use, is placed outdoors and fixed at an angle of α, as shown in Fig. 5, the solar heat collector plate 2 is placed on the upper layer (the sunny side ), the air heat exchange plate 4 is placed on the lower layer (the shade side), and the two functional plates are separated by the heat insulation plate 1, so no direct physical heat transfer occurs. The air heat exchange plate 4 positioned at the lower layer is protected from ice, snow, and dust due to the shielding of the upper layer, and can transfer heat with the surroundings without hindrance.

As shown in Figure 4, it is an application system of the binary solar polymer panel of the aforementioned embodiment. When the system is working, the low-temperature and low-pressure refrigerant medium first flows into the binary solar polymer panel for heat exchange through adiabatic expansion (capillary tube) The plate 4 and the ambient air have a large space of natural convection heat exchange, through the 42 sets of cold medium medium circulation tubes and 45 sets of heat exchange fins in the air heat exchange plate 4, the phase change of the cold medium medium, from liquid to gas, absorbs the outside air With a large amount of heat energy, the temperature of the cold medium rises rapidly until it reaches the ambient temperature;

The cold medium that rises to the ambient temperature flows from the cold medium outlet interface 44 of the air heat exchange plate 4 on the shaded side through the matching connecting pipe, and flows into the heat collecting pipe 23 through the cold medium inflow joint 24 of the solar heat collecting plate 2; the solar heat collecting plate 2 Receive solar radiation to convert solar energy into heat energy. Due to the heat insulation effect of the glass cover 3, the solar collector plate 2 loses very little heat outward, similar to a black body structure; the temperature of the cold medium flowing through the heat collector tube 23 is quickly heated to a temperature higher than that of the environment Above the temperature, when the sun shines directly at noon in summer, the highest temperature can reach 150°C. The cold medium can directly exchange heat in the heat exchanger (condenser) without passing through the compressor to turn cold water into hot water;

The high-temperature refrigerant gas medium flows out from the refrigerant medium outflow joint 25 of the heat-collecting tube 23 of the solar collector plate 2 to the compressor, and after the gas is adiabatically compressed, the gas temperature further increases; the high-temperature and high-pressure refrigerant gas enters the heat exchanger (condenser ) for heat exchange, releasing heat into the water to raise the water temperature, and at the same time, the cooling medium is liquefied into a high-pressure liquid after being cooled, and undergoes adiabatic expansion (capillary) to form a low-temperature and low-pressure liquid that recirculates into the air heat exchange plate 4.

During the daytime when the light is relatively good, the binary solar polymeric panel mainly absorbs heat from the solar collector panel 2, and at night, the large-space natural convection heat exchange between the air heat exchange panel 4 and the ambient air plays a major role. Under normal circumstances, the compressor works; when the temperature of the refrigerant medium is high enough (>90°C), the compressor stops working, valve 1 is opened, the refrigerant is directly delivered by the circulating pump, and valve 2 is opened at the same time, the refrigerant is not throttled down. The voltage directly participates in the cycle, thereby reducing power consumption.

The above embodiments and application examples are descriptions of specific implementations of the present utility model, rather than limitations of the present utility model. Those skilled in the relevant technical fields can also make various Therefore, all equivalent technical solutions should be included in the patent protection scope of the utility model.
