[0001] GREENHOUSE DRYING SYSTEM WITH HEAT TRANSFER FLUID

[0002] TECHNICAL FIELD

[0003] The invention; it is related to the greenhouse drying system with heat transfer fluid, which is used to dry the food in the greenhouse by quickly transmitting the heat accumulated in the photovoltaic thermal collector with the heat transfer fluid that can change phase.

[0004] The invention especially; it takes the heat accumulated at the back of the photovoltaic thermal collector with the help of heat transfer pipes and transmits it to the heat exchanger, transfers the heat to the air in the heat exchanger, and contains between 10-200 nanometers colemanite, borax, AI2O3, SiOs, CuO, TiCh, SiL, boron carbide, szaybelite, boron solid particles. The greenhouse contains a phase-changing heat transfer fluid that cools slowly thanks to the nano-sized solid particles that are present and allow rapid heat transfer by evaporating with the heat received in the photovoltaic thermal collector, and after the heat transfer, they hit the inner walls of the heat transfer pipes and heat exchanger during condensation, it is related to the drying system.

[0005] KNOWN STATE OF THE TECHNIQUE

[0006] The traditional method of drying food is to dry foodstuffs in the open air under direct sunlight. However, drying with direct sunlight is not effective on a large number of foods. One of the reasons for this is that it is difficult to examine and overview the food against any negative effects such as darkening of the food due to open air. With greenhouse dryers, adverse conditions that may occur in foods dried indoors are minimized.

[0007] Thanks to their closed systems, greenhouse dryers protect food from rain, dust, insects, etc. It provides a hygienic environment by protecting it from animals. By preventing the food from receiving direct sunlight, spoilage on the product is prevented. In this way, the number of wastages that may occur during drying is minimized and profit is increased.

[0008] Greenhouse dryers with solar collectors require a thermal solar panel to absorb heat, a heat exchanger to transfer heat from one heat transfer fluid to another, fans to distribute hot air to the environment, and aspirators to remove moist air from the environment. In this context, the hot air delivered to the environment must not cool down during transmission, and the drying process must be carried out smoothly. In the current technique, food is dried with heat received from the sun through a solar panel. However, there are negative reasons such as slow heat conduction and heat loss occurring during the heat conduction process.

[0009] As a result, in order to solve the above-mentioned problems existing in the current technique, the need for a new economical, useful greenhouse drying system with heat transfer fluid and the inadequacy of existing solutions necessitated a development in the relevant technical field.

[0010] PURPOSE OF THE INVENTION

[0011] The present invention was developed to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field; It is related to the greenhouse drying system with heat transfer fluid, which serves to dry the food in the greenhouse at the optimum temperature by quickly transmitting the heat accumulated in the photovoltaic thermal collector with the heat transfer fluid that can change phase.

[0012] The most important purpose of the invention is to include the heat transfer system with the heat transfer fluid that can change phase. The phase-changing fluid transfers heat from the liquid phase to the vapor phase. After transmitting the heat, it condenses and returns. In the phase-change heat transfer system, evaporation is accelerated with the heat received, thanks to the solid particles between 10 and 200 nanometers such as colemanite, borax, AI2O3, SiOs, CuO, TiCh, SiL, szaybelite, boron carbide and boron. Since these nanoparticles have a catalyst effect, heat transfer is achieved quickly. After heat transfer, these solid particles do not clump and do not stick to each other during condensation. It has a high capacity to retain heat. Thanks to these nanoparticles, heat pipes can be prepared without vacuuming. There is no need for sintering or grooving or pocketing on the inner surfaces of heat pipes. Thus, it can work vertically and horizontally without shape restrictions.

[0013] Another purpose of the invention is that the heat transfer fluid contained in it does not have any flammable, explosive, allergenic, carcinogenic or pathogenic effects and does not adversely affect the environment and human health.

[0014] Another purpose of the invention is that, as a result of our R&D studies, the phase-changing fluid has a heat conduction coefficient of 16098 W / mK. Therefore, the invention reacts very quickly and provides rapid heat transfer. Another purpose of the invention is to save energy costs because it uses a renewable energy source such as the sun as a heat source and uses the electricity obtained from the photovoltaic solar collector to operate the fan and aspirator during food drying.

[0015] The structural and characteristic features and all the advantages of the invention will be more clearly understood thanks to the figures given below and the detailed description written with references to these figures, and therefore the evaluation should be made by taking these figures and the detailed explanation into consideration.

[0029] In this detailed description, the preferred embodiments of the greenhouse drying system with heat transfer fluid are explained only for a better understanding of the subject and without any limiting effect.

[0030] In figure 1, the greenhouse drying system with heat transfer fluid (10) is the subject of the invention; it consists of photovoltaic thermal collector (20), heat transfer pipes (30), heat exchanger (40), pump (50), cable (60), air pipe (70), greenhouse (80) and the fan (81) and aspirator (82) inside the greenhouse (80).

[0031] The heat received by the photovoltaic thermal collector (20) from the sun and the electricity obtained from the heat are transmitted to the system to dry the food. Thanks to solar energy, the heat accumulated at the back of the photovoltaic thermal collector (20) is transferred to the heat transfer fluid that can change phase and transmitted to the heat exchanger (40) with the help of heat transfer pipes (30). The heat transferred to the heat exchanger (40) with the phase-changing heat transfer fluid heats the air in the heat exchanger (40). Here, the heated air is transmitted to the fan (81) via the air pipe (70) and sent into the greenhouse (80) via the fan (81).

[0032] Electrical energy obtained through solar energy in photovoltaic thermal collectors (20) is carried to the fan (81) and aspirator (82) in the greenhouse (80) via cable (60). The fan (81) located in the greenhouse (80) transfers the hot air it receives from the heat exchanger (40) to the greenhouse (80) environment, thus drying the foods in the greenhouse (80). The aspirator (82), powered by electricity obtained from the photovoltaic thermal collector (20) through solar energy, removes the moist air generated during drying from the environment.

[0033] Thanks to the pump (50) located in the greenhouse drying system with heat transfer fluid (10), the heat transfer fluid that can change phase is pumped into the system.

[0034] In the invention, there are solid particles between 10-200 nanometers such as colemanite, borax, AI2O3, SiO3, CuO, TiO2, boron carbide, szaybelite, boron in the heat transfer fluid that can change phase, and evaporation is accelerated thanks to these particles and the heat received from the photovoltaic thermal collector (20). During the condensation that occurs in the heat exchanger (40) after heat transfer, these solid particles do not clump (non-clustering) and do not stick to each other. Additionally, thanks to these nanoparticles, heat pipes can be prepared without vacuuming. Additionally, thanks to these nanoparticles, heat pipes can be prepared without vacuuming. There is no need for sintering or grooving or pocketing on the inner surfaces of heat pipes. Thus, it can work vertically and horizontally without shape restrictions.

[0035] In the invention, the heat transfer fluid that can alternatively change phase may contain the above- mentioned solid particles between 10-50 or 50-100 or 100-150 nanometers. The scope of protection of this application is determined in the claims section and cannot be limited to what is strictly exemplified above. It is clear that a person skilled in the art can demonstrate the innovation set forth in the invention by using similar structures and / or apply this structure to other areas with similar purposes used in the relevant technique. Therefore, it is obvious that such structures will lack the criteria of innovation and especially surpassing the known state of the technique.
