Description

Double water tank solar air source heat pump combination device

technical field

The utility model relates to a hot water system, in particular to a double water tank solar air source heat pump combination device with double water tanks.

Background technique

At present, with the increasing shortage of conventional energy sources, solar energy, as a clean energy source, has attracted more and more attention from human beings. Solar energy has the advantages of energy saving and environmental protection, but solar heat collection systems are easily affected by climate conditions and temperature differences between day and night. Functionality cannot be guaranteed. At the same time, the air source heat pump system uses air as the cold and heat source, and uses electric energy to drive the heat pump system to absorb heat from the air and release the heat to heat water. However, when the outdoor temperature is too low in winter, the heating performance of the air source heat pump system is poor. The hot water supply demand cannot be met.

The solar air source heat pump system currently in use uses a combination of a solar heat collection system and an air source heat pump system to jointly provide heat for a hot water tank. The system can provide hot water at a fixed temperature. However, in this way, when there is no solar light due to the weather, and the air source heat pump can only be relied on as the heat source, if the amount of hot water used is small, the thermal energy supply of the system will be far greater than the user's demand, and the consumption will be higher. A large amount of electric energy causes a waste of energy.
