SUMMARY OF THE INVENTION

The present invention relates to an additional tank that is mounted to an existing geothermal system for eliminating air into the pipes, preventing the damage into tie pipes, ensuring a fluid without air and increasing the efficiency of the geothermal system.

When the geothermal system is started, a pump in shutoff circuit enables the fluid having 75% of water and 25% of methanol to circulate between a geothermal thermopump and a geothermal sensor into the ground.

The fluid entrance is located in middle of the tank connected by a tee to a connecting pipe of each side and to a shutoff valve connected to a purging and filling valve joined to an adapter that is connected to a pipe of the geothermal system.

Moreover, the purging and filling valves enable to eliminate air and do the filling into the geothermal system by means of an external pump that is connected to the geothermal system.

The fluid exit is located in bottom of the tank connected to a elbow connected to an optional pump joined to a connecting piece that is connected to a shutoff valve and to an adapter joined to a pipe of the geothermal system.

Seeing that the diameter is taller than its entering, that allows to decrease the fluid speed and separate air from fluid in directing air towards the top of the tank and the fluid towards the bottom of the tank.

A pipe having an upper transparent portion is connected by a tee to each end of the tank to visualize in all time the state of the system, and the valves are connected to the pipe for adding fluid if necessary or eliminating air.

Finally, the tank may be installed to the geothermal system without use the optional pump enabling to do again circulate the fluid coming from the tank inside the pipes of the geothermal system.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the FIGS. 1 to 4, it may be seen that an additional tank (1) of the present invention enables to eliminate air into the pipes of the geothermal system, prevent the damage into the pipes, ensure a fluid without air and increase the efficiency of the geothermal system.

When the geothermal system is started, a pump in shutoff circuit enables the fluid having 75% of water and 25% of methanol to circulate between a geothermal thermopump and a geothermal sensor into the ground.

The fluid entrance is located in middle of the tank (1) connected by a tee (8) to a connecting pipe (11) of each side and to a shutoff valve (7) connected to a purging and filling valve (6) joined to an adapter (10) that is connected to a pipe of the geothermal system.

Moreover, the purging and filling valves (6) enable to eliminate air and do the filling into the geothermal system by means of an external pump that is connected to the geothermal system.

The fluid exit is located in bottom of the tank (1) connected to a elbow (13) connected to an optional pump (2) joined to a connecting piece (14) that is connected to a shutoff valve (3) and to an adapter (10) joined to a pipe of the geothermal system.

Seeing that the diameter of the tank (1) is taller than its entering, that allows to decrease the fluid speed and separate air from fluid in directing air towards the top of the tank and the fluid towards the bottom of the tank.

A pipe (9) having an upper transparent portion is connected by a tee (12) to each end of the tank (1) to visualize in all time the state of the system, and each valve (4)(5) are connected to the pipe (9) for adding fluid if necessary or eliminating air.

Finally, the tank (1) may be installed to the geothermal system without use the optional pump (2) enabling to do again circulate the fluid coming from the tank inside the pipes of the geothermal system.
