A fogging apparatus for atomizing a medium includes an atomizer chamber defined by an atomizer chamber wall extending substantially from a supply side to a distal outlet side, at least one supply located at the supply side of the atomizer chamber for dispensing the medium to be atomized and an air supply duct extending from an air flow source to an air supply opening on the supply side of the atomizer chamber, the air flow source being adapted to, in operation, generate an air flow, such that the air flow is fed through an air heating unit into the air supply duct and wherein at least a portion of the air supply duct is configured to be in a heat exchange contact with the atomizer chamber wall.

A compound energy co-generation system converts forestry, agricultural, and similar biomass to energy at the source farm. A working fluid reserve at the base is coupled with a boiler inlet. The boiler has a combustion chamber, a vertically rising exhaust stack, and a liquid jacket around the combustion chamber and rising from the working fluid reserve. The liquid jacket receives thermal energy from the combustion chamber and converts a portion of the liquid working fluid into a gas to create a dual-phase working fluid. A reciprocal fluid container, which in one embodiment is a piston and in another is a sealed and insulated container, receives the elevated liquid working fluid. The change in weight drives a power conversion system to convert lowering of the fluid container into electrical energy. Additional ordinarily wasted energy components are employed to perform useful work to improve overall efficiency.

A natural convection roof device includes a first roof drainage panel, a first extended roof drainage panel, a second roof drainage panel, an inner barrier and an inner roof containing an inner ventilation opening disposed obliquely to the first roof drainage panel. The top end of the first roof drainage panel includes the first extended roof drainage panel, and the top end of the first extended roof drainage panel is assembled with the second roof drainage panel and the inner barrier. The bottom ends of the second roof drainage panel and the inner barrier are installed on the inner roof. The lower side of the inner barrier is center ventilation openings. Above the second roof drainage panel is ventilation holes, and below the second roof drainage panel is drain holes. The level of the ventilation holes is higher than that of the inner ventilation opening.

A controlled environment enclosure features a heating and cooling system and a control system linked to the heating and cooling system for control of same. The control system being operable to switch between an environmental control mode for achieving user-prescribed environmental conditions within the interior space and a sterilization/pasteurization mode for heating contents of the internal space to values within a range sufficiently elevated above the prescribed environmental conditions to sterilize/pasteurize said contents of the internal space. The built-in sterilization/pasteurization function reduces or eliminates the need for personnel to physically wash down the interior space of the enclosure with cleaning chemicals.
摘要:
A shell with a controllable indoor climate. The shell may house plants, such as produce, for farming purposes. The shell may be made of scalable structurally insulated panels. Within the shell may be trays for facilitating the growth of the plants. Lighting, climate, and nutrients may be controlled for the proper growth of the plants.
摘要:
A desalination greenhouse of the invention provides both winter and summer crop growing operations and to produce a source of potable water given an input of only brackish or sea water. A consistency of temperature is produced by insulation and compensating absorption of heat in summer, with the release of heat in winter to keep crops more isothermal, but without obstructing natural light transmission to the crops. A very thin layer of brackish or salt water is evaporated from an inner shell and condensed onto an outer shell. Supplemental heat exchange can be applied to cool water used for crop irrigation.

A farm greenhouse monitor and alarm management system based on the Internet of things with real-time monitoring environmental parameters, which is aimed at monitoring and managing the growth of crops in the farm greenhouse, includes mobile inspection devices, data acquisition units, data receiving devices, REID devices and data storage servers. The system can automatically collect such greenhouse environmental parameters as air temperature, air humidity, illumination, soil temperature and soil moisture etc. and also automatically judge the critical value of every parameter and alarm otherwise. It utilizes ZigBee chip integrated wireless sensors and data collecting modules. This system provides inspection devices, which lowers the requirements for practitioners and reduces the cost of automatic management of the farm greenhouse.
摘要:
A plant growth system for growing one or more plants in a computer controlled environment, the computer controlling the environment according to a formula. The system is connected to a data exchange and communication center over the internet for sharing and distribution of formulas for controlling plant growth in the system.
摘要:
The present invention relates to a method for illuminating plants in a greenhouse, comprising the provision of a lamp above the plants, with adjustment of the distance between the lamp and the tip of the plants growing upwards to the height of the growing plants, this distance being kept between 80 cm and 240 cm. The present invention furthermore relates to a greenhouse, containing plants and an installation for illuminating plants, wherein the installation comprises a lamp, lifting gear for moving the lamp in the height direction relative to the plants and control means for measuring and/or setting the distance between the lamp and the tip of the plants growing upwards, and also relates to an installation for illuminating plants intended for use in such a greenhouse.
