The air pipe 30 passes through the evaporator 23, and two ends of the air pipe 30 are respectively inserted into the air outlet hole 11 and the air inlet hole 12. Preferably, one end of the air pipe 30 close to the air outlet hole 11 is provided with the fan.
The two ends of the air pipe 30 are extended into the storage area to provide sufficient cold air for the air pipe and ensure the indoor temperature of the storage area, thus effectively maintaining the freshness of fruits and vegetables and prolonging the shelf life of the fruits and vegetables.
In an embodiment, a cellar 10 is used as the storage area, the cellar 10 is sealed, the cellar 10 is used for storing fruits, and the air outlet hole 11 and the air inlet hole 12 are arranged above the cellar 10. The two ends of the air pipe 30 respectively pass through the air outlet hole 11 and the air inlet hole 12.
It shall be mentioned that the above-mentioned working medium capable of changing in gas and liquid comprises substances such as ammonia or freon, which can generate heat transfer when being contacted with high-temperature substances, thus changing from liquid to gas, and then taking away the heat from the high-temperature substances such as hot air to realize the cooling effect.
In an embodiment, the ammonia is used as the working medium in description, when the ammonia is added into the device for use, water is also required to be added as an absorbent to form ammonia water.
Concentrated ammonia water is heated in the generator 21 during use, and the concentrated ammonia water forms ammonia gas and dilute ammonia water after heating and rectification. It shall be mentioned that the concentrated ammonia water refers to ammonia water with ammonia concentration of 34% to 36% under 180° C. and 20 atmospheric pressures, while the dilute ammonia water refers to ammonia water with ammonia concentration of 18% to 22% under 35° C. and 20 atmospheric pressures. The ammonia gas enters the condenser 22 along with the pipeline for cooling to form liquid ammonia, which is introduced into the evaporator 23. Meanwhile, hot air in the cellar 10 enters the evaporator 23 through the air pipe 30 under the drive of the fan, so that the ammonia water in the evaporator 23 exchanges heat with the hot air to take away the heat in the hot air. Finally, the cooled cold air is inputted into the cellar 10 through the air outlet hole. With reference to
It shall be mentioned that before the device starts to work, hydrogen gas can be filled into the device and enters the pipeline of the evaporator 23 through the third feed convey pipe 243 to reduce a pressure of liquid ammonia, thus reducing a boiling point and enhancing a heat exchange capability.
Another point that shall be mentioned is that during the work process, the ammonia gas and the hydrogen gas are continuously circulated in the device, so that the device is more environment-friendly and saves cost. In addition, since the refrigerating device is generally built in rural areas, the rural areas can provide a large amount of land areas, and the structure of the device is very simple, the problem of storage of the vegetables and fruits is effectively solved for fruit growers.
According to the refrigerating device described in the first aspect of the present disclosure, the heating device 211 comprises a heating furnace arranged below the generator 21. The liquid ammonia in the generator 21 is heated to accelerate the distillation of concentrated ammonia, so that ammonia gas enters the condenser 22 for cooling.
In some embodiments, with reference to
The whole device is arranged on a vertical plane to provide a conveying power for substances in the pipeline by using the effect of gravity. In addition, since the recovery tank 25 is arranged at a lower part of the evaporator 23, the third feed convey pipe 243 will be in a vertical state. When the second feed convey pipe 242 inputs dilute ammonia water into the recovery tank 25, the hydrogen gas will be separated and inputted to the evaporator 23 through the third feed convey pipe 243, without the need for other power, thus saving energy consumption.
In some embodiments, with reference to
The device is arranged on the vertical plane. Therefore, a communicating device is formed between the first feed convey pipe 241 and the second feed convey pipe 242. Due to the principle of the communicating device, the dilute liquid ammonia in the first feed convey pipe 241 can fill the second feed convey pipe 242, so that the dilute liquid ammonia can fully enter the recovery tank 25.
According to the refrigerating device described in the first aspect of the present disclosure, the generator 21 and the condenser 22, the condenser 22 and the evaporator 23, the evaporator 23 and the recovery tank 25, as well as the recovery tank 25 and the generator 21 are all connected through a pipeline. Pipeline communication is used to provide a flow path for the working medium.
