Due to the unmatched heat transfer of copper pipes, the company TERMOCASA decided to use them in the manufacture of heat exchangers for heat pumps. In some cases, the phenomenon of corrosion occurs due to the presence of air in the heat exchangers (accidentally or due to faulty installation), especially when using submersible pumps.
As is known, copper pipe in contact with water forms an oxide layer that protects the copper for decades, but if the water contains air bubbles or if the copper pipe is repeatedly exposed to air and water, this phenomenon leads to the oxidation of the copper pipe and the appearance of green/blue corrosion spots, and finally the copper pipe is perforated. The Hydrodynamic Basin has the role of mediating the transfer of water between the submersible pump and the heat pump and eliminating the risk of air entering the heat pump.
The hydrodynamic basin has a diameter of 74cm (the diameter can be narrowed/flattened up to 60cm due to the elastic material from which it is made) and a height of 74cm, it can be placed close to the heat pump.
After connecting the hydrodynamic pool to the heat pump and the groundwater extraction pump, both electrical and hydraulic connection according to the images below, for hydrodynamic balancing, we recommend using the graduated scale in Fig.3 to adjust the flow of the two pumps (the water pump from the ground and the surface pump attached to the hydrodynamic pool) from the two taps located on the body of the pool, so that the water level in the pool must grow with a gradation every 5 minutes, and in this way the ground water pump will not have frequent starts and will be protected, and the heat pump will be able to work for decades without service problems due to perforation of the heat exchangers.
If when the heat pump stops working, the water level in the pool drops, then the drain pipe of the heat pump (cold outlet) will have to be positioned higher to prevent water from draining from the heat pump through the phenomenon (principle) of communicating vessels.
