DETAILED DESCRIPTION
[0059] In an exemplary embodiment, an Environmental Optimization System (“EOS”) provides a system for the intelligent control and monitoring of a poultry house environment and livestock through the utilization of a solar thermal collection system, a variety of environmental sensors, apparatus for controlling the thermal collection and existing interior heating/air conditioning/ventilation (“HVAC”) systems and Internet or “cloud” based intelligent control and monitoring capability of the system.
[0060] Other exemplary applications include embodiments in which EOS is utilized for residential and greenhouse or other housed agriculture environmental control. Various residential and agricultural embodiments include solar thermal collection components.
[0061]
[0062] The EOS in this embodiment includes capabilities for remote monitoring 107 of the system sensors and video 108 by the facility operator 109, as well as analytics of the environmental conditions, livestock behavior production output 110. Data from the livestock environment 101 by uplink to the Internet (cloud) 111. Control, access, storage analytics may be hosted in the cloud 111 or in an offsite server system 113.
[0063] In certain embodiments the solar thermal collector 103 is a fabricated transpired solar collector (“TSC”) with EOS control of thermal ventilation and the angle of incidence of the solar panel to the sun. The incident angle of the sun to the solar collection surface may be adjusted by modifying the elevation angle of a normal to the solar collection surface by vertical tilt, or by adjusting the radial angle of incidence by rotational adjustments of the solar facing surface.
[0064] An embodiment of EOS control and data monitoring modules is shown in
[0065] The EOS system in various embodiments includes various data collection and processing aggregation modules 201 206 214. The primary data collection module 206 receives onsite 207 and offsite inputs 204 and sends output as the system directs, to the control modules 214 and the data monitor, logging and analytics modules 201. Data monitoring includes the live video feed, which is provided through the cloud 202 along with other logged 203 and live sensor data. Controller outputs are sent from the primary module to the solar collection control module and the facility HVAC control module. The EOS system operates in various embodiments by an integrated control of the solar thermal collection and ventilation and HVAC apparatus, including either forced air or radiant heaters 212, which are on-site at the poultry house livestock facility 211.
[0066] In various embodiments, a solar thermal collection apparatus is used as a controlled component by the EOS. An embodiment of solar thermal collection control operation is shown by flow chart in
[0067]
[0068]
[0069] In various embodiments, data collection, monitoring analytics provide information relevant to the EOS controller and to system operators. In
[0070]
[0071]
[0072]
[0073]
[0074] In various embodiments, during certain times the house is vacant of poultry and the detritus from bottom of the house 813 is either cleaned out manually, or dried out during a clean out period. Experimental results show that under certain conditions, sun heated air in the solar enclosures may be 80° F. or more above the ambient air and with an 18% or more reduction in the ambient humidity of the outside air pulled through the solar collector. Given the amount of available heat, the EOS may be utilized in certain embodiments to raise house interior temperatures to the maximum temperature needed without supplemental fuel usage. Empirical analysis indicates a potential for a 20% to 50% or more reduction in clean out time of the house utilizing EOS controlled TSC solar enclosures depending on the time of the year and ambient temperature conditions.
[0075]
[0076] Once the house optimal temperature is reached under these conditions 904-910 and according to the heat storage temperature 910 the enclosure heat may be diverted into the storage volume 913. Otherwise, the enclosure vents are closed and fan remains off while heat builds up in the enclosure 912.
[0077] When the exterior temperature drops at night and no heat is available from the enclosure 902-905, the stored heat (if hot enough 906) may be used to heat the house interior 908. Otherwise, residual enclosure heat may be used to build heat in storage, performing in some embodiments a thermal insulation effect for the interior.
[0078] For various embodiments the system components may be installed in combination with an existing structure HVAC system to minimize energy or fuel necessary to maintain the structure interior environment at optimal environmental conditions.
[0079] For various embodiments the system components are not directly integrated with the HVAC system, but the house ventilation cycle is modified according to experimental results of the EOS system. For example, a common current configuration for poultry housing is for the large high-volume tunnel fans to be programmed for periodic operation to remove ammonia from the house interior. A typical ventilation system may operate the tunnel(s) fan at full speed for perhaps 5 seconds every minute. In various embodiments, without directly integrating the EOS system with the current housing ventilation system, experimental results will demonstrate the amount of ammonia reduction provided by the EOS system, and the ventilation system may be reprogrammed or adjusted to reduce the ventilation tunnel fan operation for example to 5 seconds every 5 minutes. Since tunnel fan operation is extremely noisy and causes near windy conditions inside the house, the operation of the fans is detrimental to the health of the poultry. Hence minimizing the operation of the fans by the use of various embodiments of the EOS system improves the poultry health, reduces ammonia gasses in the interior environment, and decreases supplemental energy usage.
[0080] For various embodiments the system maintains a database of optimal structure interior temperatures and conditions with associated dates and times according to empirically determined optimal conditions during the growth life cycle of the livestock in the structure. For various embodiments the system may be manually reset to restart the growth cycle environment control, or may automatically reset according to sensor input indicating that a new growth cycle of livestock in the structure has begun.
[0081] For various embodiments, the solar collector components are designed for modular construction and may be configured with end collector units and center collector units such that each system has end units and at least one center unit, each unit having its own ventilation, fan, and sensor components based on the system needs and are electronically interconnected. In various embodiments, the system utilizes locally networked Supervisory Control and Data Acquisition (SCADA) controller and sensors, including Programmable Logic Controllers (PLC) to control individual fans, vents, dampers and other components, and to acquire sensor input from networked interior and exterior sensors. The SCADA network may be integrated with existing HVAC controller systems in various embodiments through the use of HVAC system Application Programming Interface (API) access to the existing HVAC system.
[0082] An alternative embodiment design for a solar collector unit is disclosed herein as an alternative embodiment which provides improvements in simplicity of construction, durability, and solar collector thermal efficiency in certain applications. This embodiment utilizes a shallow box which may be more optimally oriented to incident sunlight and provides for a smaller volume of air in the collector per unit of area for solar absorption and to improve the volumetric heating efficiency in certain applications. This alternate embodiment utilizes a selected woven polymer material as its solar radiation absorber with a textile weight of 5 oz/sq. yard. The material utilized, which is a type of geotextile, has several properties in addition to its thermal characteristics, which make it ideal. The solar radiation absorber fabric is resistant to UV degradation, highly durable, and tested as a geotextile under ASTM D5261. Embodiments suited to implementations under various environmental conditions may utilize other geotextile materials, including non-woven geotextiles, but generally with a minimum textile weight of 5 oz/sq. yard.

[0092] In an alternative embodiment of the system developed for poultry livestock, the livestock house is divided into zones. During the life cycle for broiler poultry, the young chicks are often grouped into a single end of a poultry house. As the chicks grow, the area of the house made available to them is expanded until the full house is utilized.

[0104] Additional embodiments of the collectors allow an adjustable single tilt axis for the collector by the installer of operator of the EOS system. Details of a single axis tilt adjustable embodiment are shown in
[0105] In various embodiments, the tilt angle is adjusted dynamically according to time of year, where the optimal angle ranges from its minimal value (with the sun in the highest position above the horizon) at the summer solstice to its maximum value (with the sun at the lowest position above the horizon) at the winter solstice. In other embodiments, the tilt angle is adjusted dynamically according to the real-time position of the sun overhead. In certain embodiments, both the overhead angle and angle with respect to the horizon are dynamically adjustable. Such an embodiment implements 2 tilt axes for tracking the solar incident angle. Since efficiency of solar absorption drops off substantially near sunrise and sunset, the tilt angle range may be limited to an efficiency range.
[0106] The implications of the present invention's numerous potential configurations and embodiments are far reaching. Other embodiments include any livestock housing, grow houses for tropical plants, germination, or out of season cultivation, or as an energy saving system for human inhabited structures.
