APPARATUS FOR COMBINED HEATING, AIR CONDITIONING AND IRRIGATING OF A GREENHOUSE BA MAKING USE OF SOLAR ENERGY

摘要

The device is a functional combination of two heat sources,from heating and cooling units (2) and from sunlight,which together or alternatively supply warm air tosoil (9) of the greenhouse (1), which functions as a natural reservoirheat. Thermoregulator (6) in conjunction with thermalair temperature sensor (7) and temperature sensor (8)of the soil (9) disconnects the heating and cooling unit (2)out of service if the source of heat is sufficient from sunlight.Warm air is blown by the fan (10) to the hot aira channel (12) that extends into the distribution branches (14) storedin soil (9). At maximum air and soil temperature (9) tthe fan (10) and in the event of an overrun are also disabledtemperature above the allowable limit can be reduced by heat recoveryinto the water medium in the radiator (3) of the heating and cooling unit(2), which can be used to irrigate with substationsbranches (14). To increase the intensity of solar air heatingenergy is suspended below the fan level (10)heat absorbing screen (17).
