Vertically Integrated Greenhouse

A vertically-integrated greenhouse for growing plants in suspended trays. The design is particularly well-suited for installation in a double-skin façade of a building, or in an interior atrium, lobby, or similar structure. In addition to producing food, plants can reduce building maintenance costs by providing shade, air treatment, and evaporative cooling to building occupants. The vertically-integrated greenhouse involves the use of a dynamic movable array of plant trays as a mechanical shading device. The spacings and arrangements of the trays in the tray suspension system can be adjusted on both a diurnal basis and a seasonal basis to maximize plant light capture and building shading, thereby maximizing crop yield and building energy savings, or for esthetic considerations.

HVAC start-up control system and method

A controller controls operation of a HVAC&R device, bringing the temperature inside a structure from a first temperature to a second temperature at a predetermined time each day. Sensors sense the temperature both inside and outside the structure. A recovery time is calculated based upon a previously calculated air treatment rate of temperature recovery for the HVAC&R device to drive the temperature of the structure through a temperature change, the recovery time calculation being obtained by multiplying the difference between the sensed temperature inside the structure and the second temperature by the previously calculated air treatment rate. A correction factor is calculated based upon a relationship between the sensed outside temperature and a previously sensed outside temperature, the correction factor being added to obtain a corrected recovery time. The HVAC&R device is initiated at a time defined by the predetermined time subtracted from the corrected recovery time.

High-efficiency air handler

A high-efficiency air handler that is suitable for moving large volumes of air. The air handler comprises a coil and a fan. The total air volume moving through the unit is preferably over about 2000 CFM, with a total fan static pressure rise of less than about 0.5 inches and preferably less than 0.2 inches of water. The fan is preferably a modified ceiling fan with a rotational speed of less than about 450 rpm. The air handler is preferably part of a system where dehumidification and sensible cooling functions are separate. The separate dehumidification allows for much higher supply air temperatures, preferably within about 10° F. of the space temperature. Low-velocity air distribution through a ceiling plenum or a vent into the space allows for very low fan static pressures, which greatly reduces fan energy use compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling construction with little modification. The system can also include low-cost thermal storage. Latent thermal storage is in the form of a concentrated liquid desiccant solution. Chilled water storage is another option. The result is a major improvement in energy efficiency and comfort while reducing installed cost and peak electrical demand of the system.
