Pump solar unit
A pumped solar unit is a device that is used in solar thermal systems to heat water. Its main task is to move the heat transfer medium (a mixture of water and antifreeze is often used) between the solar collectors and the hot water tank or heating system. This unit ensures efficient heat transfer from the absorption surface of the collectors to the heat-carrying medium.
Operation of the pumped solar unit:
Solar energy collection: Solar collectors collect solar radiation and the absorption surface converts it into heat. The heat-carrying medium circulates through the collectors and gains heat.
Transfer of the heat-carrying medium: The pump in the solar unit moves the heat-carrying medium from the collectors to the hot water tank or the heating system. In this way, the heat that has been collected in the heat-carrying medium is transferred to the place of use.
Connection with regulation: The solar pump unit can be integrated with the system regulation, which monitors the temperatures in the collectors and the reservoir and controls the operation of the pump based on the current state.
Use of the pump solar unit:
Hot water heating: In homes, pumped solar units are often used for domestic hot water heating, showering and other domestic uses.
Heating systems: Solar thermal systems can also be used to heat the house. The heat-carrying medium heated in the collectors can be used to transfer heat to the heating system.
Advantages of a pump solar unit:
Energy efficiency: With the help of solar energy, it is possible to efficiently provide hot water heating and heating, which can lead to energy savings.
Environmental protection: Solar thermal systems with pump units reduce greenhouse gas emissions and contribute to environmental protection.
Long life: Proper design and maintenance can ensure a long life and reliable operation of a pumped solar unit.
It is important to note that the efficiency and benefits of solar systems can be affected by various factors such as climate conditions, location and system design.
