This enclosed space under the growing floor is used as an air distribution channel to benefit environment control of the upper floor growing space.

(66) Referring to FIG. 17, the underfloor environment control components 8 and settings in different seasons are further described in detail as following. The floor panel 2 extended to the whole shed, divides the barn space into two separate parts: upper space where the birds are staying in and underneath space 9. The underfloor environmental control unit 8 includes air heating device 81, waste heat recovery device 82, air cooling device 83, inlet fan 84, exhaust fan 85, main air diffuser 86, and sub air diffuser 87. In various embodiments, the earth ground 93 can be covered with an insulation layer to reduce heat loss through the ground.

(67) With the conventional summer cooling and ventilation, the first problem is that the main air stream flows across the barn at the highest above the birds (5-10 feet, in the center of the barn section). It is not best used to improve air quality near birds at the height of 0-10 inch). The second problem of the conventional tunnel ventilation is new fresh air travel hundreds of feet from one end to another end of the shed. Large fan power is used for air movement. Air at the end of affluence is very poor in comparison with fresh air at the entrance. In the summertime, the air at the entrance is cool and fresh, but is contaminated, humid, and hot at the effluence. Due to the difference of comfort at a different location, birds are tended to move toward the fresh and comfort end of the barn. To deal with this issue, birds crowd at one end and leave the other vacant, restraining fences are common to see in poultry shed. It cost labor time to place and remove fences, and birds are still piling up at near one fence toward the fresh air direction.

(68) In the ventilation system proposed by the present disclosure, the outdoor fresh air first enters the space underneath the floor panels 2 and fills the underfloor space 9. The outdoor air could be un-conditioned fresh air or heated or cooled before entering the shed. It can be heated by the heating device 81, or cooled by cooler 83, or preheated by waste heat recover 82. Along the longitudinal conveyor 5 and the shed sidewall 91, there are major air inlet opening 86 to allow airflow from underfloor space to upper space. The minor air inlet 87 can be opened between two rows of floor panels. The major air inlet 86 and minor air inlet 87 are arranged across the whole growing floor thus ensuring that the fresh and comfortable air is evenly distributed throughout the field. Since the fresh air first passes through floor panel 2 and reach the birds, it ensures that the best comfort is provided to birds at the bird body height, instead of at high space or ceiling space. Each bird receives completely fresh air directly. Due to improved air movement and ventilation efficiency, the system requires less air amount in summer ventilation, and electric powers of fans can be reduced.

(69) Air cooling device 83 can be a common evaporative water curtain, evaporation misting cooling system, water-air heat exchanger, and air conditioner (including water or ground source heat pumps). With the conventional winter heating, the problems are that warm air always rises above (bounce flow, or natural flow), resulting in the highest temperature near the roof or ceiling of she, but the air around the bird's body is relatively lower. Similarly, as the previous embodiment for summer cooling, the underfloor environmental control component of the present disclosure, using the air heating device 81 to the heated air to require temperature and the deliver it into the underfloor space 9 through the inlet fan 84. The heated air keeps the floor panel warm and provides conform to the birds on the floor panel 2. Warm air pass through the major air inlet 86 and minor air inlet 87, distributed to upper space to replace contaminated air, and maintain air quality at an acceptable level. Air heating device 81 can be a heater of any kind, including gas heaters, electric heaters, air sources or water sources, or ground-source heat pumps. Optionally, the energy used in the air heating unit 81 includes gas, liquefied gas, natural gas or other fuels, or biomass, geothermal or solar energy.

(70) In various embodiments, before fresh air enters the air heating unit 81, it can be preheated by the waste heat recovery unit 82. Indoor warm exhaust air, by exhaust fan 85 introduced into the waste heat recovery device 82, transfer heat energy to the lower temperature of the fresh air. Waste air with reduced temperature is discharged to outdoors, and preheated fresh air then enters the air heating device 81 for further heating. The additional waste heat recovery unit 82 has proved to recover more than half of the waste heat, significantly reducing energy consumption during winter production.

(71) In various embodiments of the automatic rearing system of the present disclosure, as described herein, offer an improved environment for animals growing on a clean panel without bedding material. The animal feces is removed, and the floor is cleaned by the robot system. The robot system is also used to replace labor on dead bird collection, bird harvesting, and barn cleaning and disinfection. Robot and attached sensors, with artificial intelligence, provide a health diagnosis, early warning, and medical treatment. The automatic rearing system reduces the contact of humans and animals for better biosecurity control. Invented underfloor environment control systems provide better comfort and improve air quality at reduced energy consumption.

(72) In various embodiments, the automatic rearing system can be repeated in the horizontal direction, to result in a larger continuous growing space. The automatic rearing system can also be repeated vertically to form a multi-layer rearing structure. The upper space of the multiple-layer system can be the entire area of the shed plan or be a portion of the shed plan. As an example of a three-layer rearing system, each layer of rearing space from the bottom to the top can be 2400 square meters, 1800 square meters, 1200 square meters. It can be used to rear small birds, such as pigeons, chickens or slugs, etc.

(73) The description herein is merely exemplary in nature and, thus, variations that do not depart from the gist of that which is described are intended to be within the scope of the teachings. Moreover, although the foregoing descriptions and the associated drawings describe example embodiments in the context of certain example combinations of elements and/or functions, it should be appreciated that different combinations of elements and/or functions can be provided by alternative embodiments without departing from the scope of the disclosure. Such variations and alternative combinations of elements and/or functions are not to be regarded as a departure from the spirit and scope of the teachings.
