The ventilation system has a vital role in a closed house to provide air circulation and house temperature according to the chicken’s needs. The work process of the ventilation system can be set automatically or manually using a climate controller and power panel box. Thus, farmers need to know the basic use of the climate controller and power panel box.
Climate Controller Function
Climate controller is a means of controlling the ventilation system to achieve the temperature and humidity targets set by the farmer. The climate controller controls the automatic operation of the fan, evaporative cooling pad and central heater [1]. There are several climate controller products, for example the Temptron 607 A-C and Rotem.
Components & Function Panel Power Box
The power panel box is a tool that controls the source of electric current to each tool in the ventilation system so that it can function properly. The power panel box has 3 main components: Mini Circuit Breaker (MCB), Over Current Relay (OCR), and switch.
Mini Circuit Breaker (MCB) functions as a safety device that will cut off the voltage if there is a short circuit or an excess current from the PLN source [2], thus preventing cage fires. The MCB secures the input electric current.
while OCR (Over Current Relay) functions as an electrical safety device that will cut off the voltage if a short circuit occurs [3], thus preventing damage to the equipment.
In addition, at the front of the power panel box, there is a switch to run automatic or manual ventilation and feeding systems. For exhaust fan and cooling pad pump items, there are 3 condition options [4]:
Man : Manual and Continuous
Off : Turn OFF (manual)
Auto : Turn ON item according to the temptron program
Meanwhile, for the feeding system, there are only 2 condition options on the power panel switch box [4]:
OFF : Turn OFF feeding motor
ON : Turn ON and OFF feeding motor based on sensor that placed in the last pan feeder.
*Placement of the sensor in the pan feeder can be seen in Flash News 5th edition
So, the climate controller and the power panel box are two components that work together to produce suitable climatic conditions in the enclosure.
Electrical requirements for closed house
Please note that the exhaust fan in a closed house requires a large electric voltage (380 V) and 3-phase electricity. Meanwhile, electricity for households is generally 1-phase (220 V) [5]. The change of electricity from 1 phase to 3 phases can be requested from PLN, so that the location of the cage is ready to be installed with closed house equipment.
Item connected to the climate controller
Climate controller connected to the sensors and control unit (the controller device). There are 2 types of sensors, temperature sensor and humidity sensor. The climate controller is connected to the sensor and control unit. There are 2 types of sensors, namely temperature sensors and humidity sensors. For standard size cage closed house (120 x 12 meters), use 1 piece temperature sensors placed in the middle of the cage and 2 temperature sensors placed in the front of the cage and back of the cage (generally 1/3 of 1/3 of the front and rear cage). The sensor is used to measure the actual conditions of temperature and humidity in the cage. The sensor is used to measure the actual conditions of temperature and humidity in the cage.
Climate Controller Mechanism
The farmer needs to set the temperature and humidity target (% RH or% Relative Humidity) of the cage to be achieved on the climate controller. The process for setting the Temptron target is quite simple, and will be explained in the sub-chapter “Guide to using Temptron” in this edition of Flash News.
After the target setting process at Temptron, the climate controller will work according to the actual condition measurement (temperature & humidity) from the sensor and then instructs the control unit (in the form of exhaust fan and cooling pad pump) to work until the target setting conditions are reached.
For example, chickens aged 23 days need an effective temperature target of 26oC, so breeders need to set a temperature target of 26oC into the climate controller. Then, the climate controller will monitor the cage temperature via sensors. If at that time the temperature of the cage was 28oC, then the climate controller would order running several exhaust fans to lower the cage temperature to reach the target of 26oC.
*Note: the target chicken temperature per day can be seen in Flash News Issue 1
Control Unit controlled by the climate controller.
The control unit controlled by the climate controller is limited. A control unit controlled item is said to be 1 stage output. The Temptron 304D is only capable of controlling 4 stage outputs [7]. The Temptron 607A-C controls 8 stage outputs [1].
However, 1 stage output can be parallel for several items, to overcome the limitations of climate controller control.
Therefore, for small cage sizes (under 50 x 8 meters) Temptron 304D can be used, while for large cages (above 50 x 8 meters) use Temptron 607A-C. This depends on the number of fans, whether or not the cooling pad pump is used, and the central heater. This depends on the number of fans, whether or not the cooling pad pump is used, and the central heater.
The basic functions of the climate controller to control the control unit are: Exhaust fan, cooling pump, and central heater. Some modern climate controllers are even able to control the fluctuation of the cage curtains and lighting. Temptron 607A-C has 8 stage outputs, with the form of the control unit [4]:
The position of the exhaust fan on also needs to be considered in order to create a uniform air flow in the cage. The first and second fans are in the center of the enclosure, which serves to minimum ventilation. The light position of each stage exhaust fan can be seen in Figure 6.
Additionally, Temptron 607A-C can be connected to an alarm (as the 1 stage output). The alarm will sound when the power goes out or when the temperature exceeds the upper limit / lower than the target setting temperature. The alarm controller is placed just below the climate controller.
Guide to using Temptron 607
Temptron 607 A-C has 32 function sets, with 16 commonly used main function devices. This function is written on the front (front) of the climate controller in the form of 2 digit numbers.
To set the target on the Temptron 607 AC, do the following step :
- Press 0 button.
- Press the numeric buttons according to the desired system code.
- Press “prog” button.
- Enter the desired target number
- Press “Enter”.
Simply cases 1
If farmers do Temptron setting numerical targets on AC 607 as follows [8]:
What will happen to the closed house if :
a.) Temperature in the cage 25oC
b.) Temperature in the cage 26oC
c.) Temperature in the cage 28oC
Answer:
a.) If the room temperature in the cage is in accordance with the “Required Temp” target of 25oC, then the exhaust fan will turn on in: minimum ventilation mode, so that only Fan Stage 1 will turn on with a running duration of 1 minute and the duration of the fan being off for 2 minutes.
b.) If the room temperature in the cage is 26oC, it shows that there is a difference of 1oC hotter than “Required Temp”. This 1oC difference value is in accordance with the target setting code system 04 (Fan 1) in that case, so that the Stage 1 Fan lights up continuously. Stage 1 fans are no longer under minimum ventilation.
c.) If the room temperature in the cage is 28oC, it shows that there is a difference of 3oC hotter than “Required Temp”. This 3oC difference value is in accordance with the target setting code system 06 (Fan 3) in that case, so that Stage 1 Fan, Stage 2 Fan, Stage 3 Fan lights up simultaneously until the temperature of the cage decreases to reach the target number “Required Temp”.
Simply cases 2
If farmers do Temptron setting numerical targets on AC 607 as follows [8]:
What will happen if the room temperature in the cage reaches 30oC?
Answer:
If the room temperature in the cage is 30oC,, indicates there is a difference of 4oC hotter than “Required Temp”. So what happens is:
- Fan stage 1 and Fan stage 2 will run continuously.
- The cooling pad pump runs with a duration of “on” for 1 minute and “off” for 3 minutes.
- The alarm will sound and the alarm lamp will turn on .
Sommen Controller
If farmers want the process of setting targets on the controller is a full-featured, then Sommen controller is a solution. The Sommen controller can be connect to an internet network, so user can set target parameters online on Android or a computer connected to the internet.
Sommen Controller is equipped with inverter speed control, to control the frequency of exhaust fan motors until they reach the target cage temperature. When the exhaust fan is instructed to turn on by the conventional climate controller , the exhaust fan motor will turn on to the greatest use. Meanwhile, if you use an inverter speed control, the exhaust fan motor will turn on with the optimal rotational speed. DThus, the use of a Sommen controller (which includes an inverter speed control) will make electricity use more efficient and the exhaust fan motor will last a longer lifetime.
In addition, the Sommen controller can be integrated with the Medion livestock management software: Bird-mate Software, which functions to record data and display livestock performance calculations automatically (FCR, IP, feed intake, water intake,% of deaths, etc.). The common controller is capable of displaying actual data onto various cages.
