Iran-Made Smart Hybrid System Settles Problem of Heating in Chicken Farms

“This system consists of 10 main parts; first the air coming out of the poultry house enters the first heat exchanger. On the other hand, water enters the first heat exchanger from the water tank and heats it up a bit. The outgoing water from the first heat exchanger enters the ground, passes through the spiral pipes and its temperature increases again, and then it leaves the ground and enters the first heat exchanger which contains PCM,” Saman Aminian, a PhD student in the field of mechanical engineering (energy conversion) at Islamic Azad University’s Science and Research Branch and the managing director of Daneshafarinan Negin Mandegar company, told ANA.

He added that the oil tank containing hybrid nanoparticles is heated by passing through the inadvertent collectors and enters the second heat exchanger, noting that inside this converter, the heat of the oil is given to the PCM and through the PCM it is transferred to the water output from the geothermal system.

“Then the heated water enters the geothermal heat pump cycle, where the air passes over the hot water and reaches a proper temperature inside the poultry house. We also use flat solar panels to supply electricity to the system,” Aminian said.

He explained that the advantages of the system are decreasing energy consumption, maintenance costs, poultry mortality and pollution, and increasing product quality.

In a relevant development in January, the research center for the development of new technologies in electrical industries of Islamic Azad University’s Bojnourd branch had also succeeded in building a device that in addition to the momentary weight, records the average weight of poultry every 24 hours.

“This system was invented by a veterinarian to settle the technical problems in the poultry industry, including the processes which are time consuming, user fatigue, low efficiency and high rate of error in traditional methods by using a scale and checking standard tables,” Mazdak Teymourtashlo, the head of the research center for the development of new technologies in electrical industries of Islamic Azad University’s Bojnourd branch, told ANA.

He said that the project named ‘growth measurement and comparison with poultry standard with the ability to remove the dynamic load caused by the movement of poultry’ is used to measure the weight of different poultry like broiler chickens, mother hens, ducks and turkeys automatically and without the need for human intervention, adding that it can be programmed to assess the growth of five different types of birds concurrently.

Noting that the smart scale can be hanged from the ceiling, Teymourtashlou said that at least one device is needed in a poultry house and the basis of measurement is to register the initial weight of the chickens and their age along with their breed.

“One of the features of the smart scale is that no mistake or measurement error happens when two or more birds climb up at the same time, chicken manure is poured on the bottom, or birds lean on the bottom of the scale,” he said.
