Description

Technical Field

[0001] The invention belongs to the technical field of broiler breeding facilities, and in particular relates to a multifunctional integrated environmental control system for a broiler house. Background Art

[0002] Broilers have the characteristics of fast growth, short breeding cycle, and variable temperature requirements. When broilers are older, they have low temperature requirements and produce more heat, so they usually need to be cooled; when broilers are younger, they have high temperature requirements and are easily affected by cold stress, so they usually need to be heated. Therefore, effectively ensuring and accurately controlling the thermal environment in the broiler house is of great significance to the growth performance and production efficiency of broilers.

[0003] At present, broiler houses are generally heated by boilers, electric heaters and other equipment systems, which have high construction investment costs and are only used for a short period of time at young ages or in low temperatures in winter, with low cost performance. Broiler houses generally use a wet curtain-fan cooling system for cooling, with the wet curtain installed on one gable or side wall, and the fan installed on the other gable. Under high temperature and high humidity climate conditions, the cooling effect of this cooling system is very limited and cannot meet the requirements, and the longitudinal temperature shows obvious differences and uneven distribution. In general, the construction cost of the existing broiler house heating system is high, the cooling effect of the cooling system is poor under high temperature and high humidity climate conditions, the heating system and the cooling system are relatively independent, and there are disadvantages such as high cost, high energy consumption, and high water consumption. In addition, because broiler houses usually use different environmental control systems in different seasons, when the environmental control system is switched during the season change, it is easy to cause high mortality and high morbidity rates of broilers.

[0004] Most of the broiler houses are located in places with groundwater resources. The groundwater temperature is stable at 10℃~22℃ all year round. The groundwater in summer is a better cold source than the wet curtain, while the groundwater in winter is a heat source that can be used for preheating. Therefore, it is necessary to make full use of groundwater to control the environment of the broiler house. In the prior art, a certain farm uses a new technology for water curtains. In summer, low-temperature groundwater is transported to the inside of the chicken house through the water curtain to achieve a cooling effect. In winter, preheated hot water is transported to the inside of the chicken house through the water curtain to achieve a preheating and humidification effect. It has both cooling and heating functions, but its disadvantages are high energy consumption and large water consumption, and it is not convenient to flexibly control the temperature in the chicken house.

[0005] Therefore, it is necessary to develop a low-cost, multifunctional environmental control system that can both cool and heat the chicken house and meet the production water supply needs of the factory (drinking water for chickens, living water for staff, etc.). However, how to achieve a compact layout and high utilization rate of the system, how to avoid high incidence rates caused by seasonal changes, and how to flexibly control the temperature in the broiler house are the current technical difficulties. Summary of the invention

[0006] At least in view of the problems mentioned in the background technology, the present invention aims to provide a multifunctional integrated environmental control system for broiler houses.

Example 2

[0034] The difference between this embodiment and embodiment 1 is that: Figure 4As shown, the environmental control water pipe 8 of the chicken house 1 is bent and laid under the ground of the chicken house 1, and the laying surface of the environmental control water pipe 8 covers the entire ground of the chicken house 1; when the chicken house 1 needs to be heated, the hot water of the boiler 19 flows from the environmental control water inlet pipe 5 into the environmental control water pipe 8 under the ground until the heat is transferred to the ground, and the air inside the chicken house 1 is heated by ground radiation, and finally returns to the boiler 19 through the environmental control return pipe 6 and the heating return pipe 21 to achieve circulating heating; when the chicken house 1 needs to be cooled, low-temperature groundwater flows from the environmental control water inlet pipe 5 into the environmental control water pipe 8, directly absorbs the heat from the ground, and performs radiation heat exchange with the air inside the chicken house 1 through the cooled bottom surface, and finally enters the water storage tank 18 through the environmental control return pipe 6 and the cooling return pipe 17.

Example 3

[0035] The difference between this embodiment and embodiment 1 is that: Figure 5 As shown, a plurality of radiators 37 are provided between the water inlet and the water outlet of the environmental control water pipe 8. The radiators 37 are evenly installed on the side walls of the chicken house 1, and can also be installed in sections to positions that require more heating or cooling.

[0036] By adopting the scheme in the embodiment, the chicken house can be ventilated, heated, cooled and watered, and the groundwater can be used for heating, cooling and drinking in the chicken house. The water flowing through the drinking water pipe in the chicken house can also play a role in assisting temperature control. The functions are diversified, and the overall structure of the environmental control system is compact (compared with the existing conventional chicken houses of the same size, the area occupied by water supply and drainage in the underground space can be reduced by 20-30%, and the land utilization rate of the chicken farm is increased by 5-10% without installing wet curtains on the ground). The construction cost, operation and maintenance cost of the environmental control system can be effectively reduced (compared with the existing independent systems with equal heating, equal cooling, equal living and drinking water, especially the operation and maintenance cost can be reduced by 60%). The above), the number and cost of fan installation can be reduced by 20-40%, the overall operating energy consumption can be reduced by 20~40%, and the use efficiency is high (used all year round), and the installation and maintenance are simple; it realizes the intelligent regulation and flexible regulation of environmental control factors, and at the same time can improve the cooling capacity in the chicken house, which can effectively reduce the mortality rate and morbidity rate of broilers (especially during the change of seasons); the opening of the small window can be flexibly controlled according to the weight, age, and ambient gas concentration of the broiler, as well as the number of fans opened and the frequency of the fans; the temperature threshold suitable for broiler growth can be set according to the breed, age and weight of the broiler, and when the temperature inside the chicken house is lower than the threshold, the heating mode is started, otherwise, the cooling mode is started. The environmental control system of the present invention can realize the coordinated operation of heating, cooling and ventilation modes, and only the minimum ventilation needs to be maintained inside the chicken house, which reduces the use of fans and reduces energy consumption; and in the cooling mode, groundwater can be recovered and purified as domestic water. Compared with the existing chicken houses that use water curtains for cooling, it can greatly save water resources and is eco-friendly. At the same time, the use of non-water evaporation methods for cooling also improves the cascade utilization of water resources. Example 4

[0037] The difference between this embodiment and embodiment 1 is that: Figures 6 to 8 As shown, the chicken cage support frame 40 in the chicken house serves as a part of the environmental control water pipe 8 (that is, the water in the environmental control water pipe 8 can flow along the liquid flow channel 42 of the chicken cage support frame 40), and the chicken cage support frame 40 is composed of a plurality of interconnected angle steel components 43, and the angle steel component 43 has a plurality of liquid flow channels 42, and adjacent liquid flow channels 42 are separated by a partition 41. When in use, the water used for cooling or keeping warm in the chicken house flows through the liquid flow channel 42 of the chicken cage support frame 40, so that the temperature of the broiler living area can be accurately controlled, and the heating and cooling effects of the broiler living area can be significantly optimized, which is more conducive to saving energy consumption. By adopting the scheme in this embodiment, the temperature error of the broiler living area (inside the chicken cage) can be controlled within ±0.3°C.
