Air handling unit for use in a greenhouse

An air treatment unit for use in a greenhouse. The unit provides an efficient, robust and easy to assemble and transport means of drawing air and/or gas into a greenhouse distribution pipe.

The unit also provides an efficient means for adjusting the temperature of air entering the aggregate’s air distribution piping by causing more incoming air to be exposed to a temperature adjustment element. The unit includes a housing, an air inlet, an air outlet, a fan and a temperature adjustment element.

Adjustable end cap for use with a greenhouse distribution line

A device with an adjustable end cap used with distribution pipes in a greenhouse. The device provides a solution for sealing the end of a distribution pipe while further providing means to control the diffusion of substances such as air or gas.

The device includes a structure for sealing the end of a greenhouse distribution pipe whereby the sealing structure can be freely adjusted. Variable amounts of air or gas can be allowed to escape from the sealed end. The design allows for further control of pressure and temperature in the pipe, extension of climate control over a greater distance and the ability to control pipes on an individual basis.

Closed energy neutral air drying system

Systems and practices for dehumidifying or drying air in a greenhouse while cooling it. Air to be cooled is drawn through a cooling medium and the systems and practices use heat extracted from the warm air before the cooling mechanism for heating the cooled air coming out of the cooling mechanism. The reintroduction of the extracted heat into the air therefrom makes humidity control while a lower temperature compared to the temperature of the air as it enters the cooling mechanism. Various embodiments according to the present invention closed-loop, energy-neutral air drying systems that can use no external energy or materials to dry the air. This provides an energy efficient air drying system that allows a greenhouse to reduce their operating costs.

Greenhouse and forced greenhouse climate control system and method

A greenhouse is usually an enclosed growing section with an enclosed end wall adjacent to the growing section. End wall is arranged to control the air flow into the growing section. air distribution tubes are incorporated into the growing section the tubes arranged to provide for essentially uniform air flow into the growing section. The air tubes may also be arranged to compensate for heat difference between the air in the tubes and in the growing section.
