Abstract
An apparatus and method for supplying an aqueous liquid for plants utilizes a reservoir having inside walls. There is a conduit for discharging the liquid so the liquid flows along walls of the reservoir. There is a cooler for cooling the walls so the liquid flowing along the walls is thereby cooled. For example, the reservoir may comprise a converted chest-type freezer unit. There may be an opening in the walls of the reservoir and the fan located in the opening to direct air into the reservoir and aerate liquid therein.
Claims18
An apparatus for supplying an aqueous liquid for plants, comprising:
- an enclosed reservoir having inside walls and an opening in the walls of the reservoir;
- a fan located in the opening to direct air into the reservoir to aerate the liquid;
- conduit for discharging the liquid so the liquid flows along the walls of the reservoir;
- and
- a cooler for cooling the walls so the liquid flowing along the walls is thereby cooled.
An apparatus for supplying an aqueous liquid for plants, comprising:
- a reservoir having a top and inside walls;
- a conduit near the top of the reservoir for discharging the liquid so the liquid flows along the walls of the reservoir, the reservoir having a pool of liquid below the conduit, whereby the liquid flows over the walls and downwardly to the pool of liquid;
- a cooler for cooling the walls so the liquid flowing along the walls is thereby cooled;
- and
- a pump operatively connected to the conduit for pumping liquid from the pool of liquid to the conduit.
An apparatus for supplying an aqueous liquid for plants, comprising:
- a reservoir having a top and inside walls;
- a conduit near the top of the reservoir for discharging the liquid so the liquid flows along the walls of the reservoir, the reservoir having a pool of liquid below the conduit, whereby the liquid flows over the walls and downwardly to the pool of liquid;
- means for regulating the depth of the pool of liquid, the means for regulating including a float mechanism;
- and
- a cooler for cooling the walls so the liquid flowing along the walls is thereby cooled.
A method for treating an aqueous liquid for plants, comprising the steps of:
- providing a reservoir for the liquid;
- providing a pool of the aqueous liquid in the reservoir;
- regulating the depth of the pool of liquid, the reservoir having walls extending above the pool of liquid, the liquid being directed along the walls and flowing downwardly into the pool;
- and
- cooling the reservoir and thereby cooling the aqueous liquid.
An apparatus for conditioning an aqueous liquid for plants, comprising:
- a chest-type freezer unit having an interior, a top, a bottom, side walls and an opening in the side walls;
- a fan mounted within the opening for directing air into the unit;
- a spray bar extending about the interior of the freezer unit adjacent the side walls and adjacent the top thereof;
- a conduit for supplying the aqueous liquid to the spray bar;
- means for regulating a pool of liquid in the interior of the freezer unit, whereby the side walls extend above the pool of liquid so liquid discharged from the spray bar flows over the walls and downwardly to the pool;
- a discharge conduit for conducting liquid from the freezer unit to plants;
- and
- an intake conduit for returning liquid from the plants to the freezer unit.
