Some equipment needed for the environmental control of the duck house

1. The ventilation equipment is usually a fan, which is mainly used to discharge the dirty air in the house, to send the fresh air into the duck house or for the air flow in the house. It has the characteristics of full pressure, large air volume, low noise, energy saving, smooth operation, automatic opening and closing of blinds, convenient maintenance and so on. It is suitable for both longitudinal and horizontal ventilation in the duck house, and it is an ideal ventilation equipment for the indoor duck industry.

The ventilation of duck house has different classification methods. According to the direction of air flow in the house, it is generally divided into three types: transverse ventilation, longitudinal ventilation and combined ventilation. During transverse ventilation, the air flow enters from one side of the duck house, and the fan will be evenly distributed. During longitudinal ventilation, the fan is at one end of the duck house (the gable), and the air flow enters from the opposite end of the duck house. During the joint ventilation, the air inlet is evenly distributed on the walls on both sides of the duck house, and a fan is installed at one end of the duck house, combined with the exhaust fan on the roof.

two。 Cooling system, wet curtain cooling system. The system is mainly composed of wet curtain and fan.

There are usually two kinds of wet curtain: ordinary medium and reinforced medium. the ordinary medium is made of corrugated fiber paper by adding special chemical composition and special post-process treatment to the raw materials of papermaking. therefore, it has the characteristics of corrosion resistance, high strength and long service life. The enhanced medium adds a black hard coating to the surface of the ordinary medium through a special process, which makes the paper pad easy to scrub and disinfect, effectively solves the problem of all kinds of flying catkins in the air, shading, anti-mouse, and longer service life. The wet curtain cooling system uses the principle of heat exchange to humidify and cool the air. The water is sent to the top of the wet curtain through the water supply system so that the surface of the wet curtain is wet. when the air passes through the wet curtain, the water is in full contact with the air, which reduces the temperature of the air and achieves the purpose of cooling. The temperature can be reduced by 5 to 8 ℃ in summer, and the higher the temperature is, the greater the cooling range is. With low investment and low energy consumption, it is called "cheap air conditioner". The air is fresh, the temperature is balanced and the humidity can be adjusted to the best condition. Wet curtain ventilation has the advantages of low investment and high benefit, which is especially suitable for aquaculture production.

Spray cooling system: the system is composed of various types of atomization nozzles and pressure pumps connected to the pipeline.

The spray cooling system is a very efficient evaporation system that sprays tiny droplets into the duck house through high-pressure nozzles. With the increase of humidity, the heat energy (solar light + duck body heat) is converted into evaporation energy, and the temperature drops to the desired value in a few minutes. As the water sprayed is absorbed by the air in the house, the ground remains dry all the time. This system can also be used for disinfection, thus improving the health of ducks. Because the system can reduce the temperature efficiently, the ventilation rate can be reduced to save energy. When the microenvironment in the house is required to be suitable and hygienic, it can be used throughout the year. The system has the characteristics of summer cooling, spray dedusting, continuous humidification, environmental disinfection and year-round control of fresh air.

The chiller has the advantages of good cooling effect, moist air purification, low pressure, large flow, low power consumption, low noise, fast refrigeration, stable operation, safety and reliability, low operation cost, simple operation and convenient maintenance.

3. The lighting program controller of the lighting control equipment is designed with a microcomputer chip, the lighting brightness is stepless, and has the function of automatic photometric control. Automatic lighting-ventilation dual-purpose controller can not only automatically control the lighting system, but also connect wet curtains, fans, air heaters and other equipment for automatic time control.

4. Cleaning and disinfection equipment cleaning equipment is mainly high-pressure washing machinery, with atomization sprinkler can also be used as disinfection equipment. There are two kinds of disinfection equipment: manual knapsack sprayer and mechanical power sprayer.

5. The environmental monitoring and control integrated system control system is the heart part of any environmental monitoring system, which is used for effective monitoring and automatic control of environmental factors such as heating, cooling, air intake, illumination and so on.

⑴ simple microenvironment climate controller. It only has the most preliminary functions of micro-environment climate control, ventilation, heating and alarm. The installation and operation of this controller is very simple, it can be connected to the computer, the information management is centralized, and the control strategy can be distinguished. It ensures that the temperature of the duck house is kept in the duck's comfort zone as much as possible and always meets the requirements of minimum fresh air.

⑵ advanced environment control integrated system. It is composed of main controller, temperature sensor, humidity sensor, water meter sensor, material level sensor, alarm device, modem, application software and so on. Through the setting of relevant parameters, the information collection of different induction devices and the instruction feedback of the main controller, the integrated control of environmental factors such as temperature, humidity, lighting, ventilation, water supply, spray and so on is achieved.
