Heat Pump Technology Creates a New Chapter in Comprehensive Utilization of Energy

Summary of contents: The combination of solar hot water systems and heat pumps on the market today is very different in its system technology. Vendors are committed to various conceptual innovations in control management and energy storage technologies. However, it is obvious to all that the development of solar energy has priority.

It is understood that in order to prevent solar energy, air energy and ground energy from developing in independent ways, solar heat pump systems must be matched in terms of pressure and control technology. Most suppliers try to increase the overall performance of the system by utilizing the output of solar hot water systems, regardless of the temperature of solar hot water systems.

One way is for the collector to transfer thermal energy to a specific hot water or combined storage tank in a temperature-sensitive manner, as in a system that uses a heat pump as a conventional auxiliary device. In addition, some manufacturers also use the air-source heat pump's boil-off gas or use geothermal and other renewable energy sources combined with ground-source heat pumps. Utilizing these two systems operating on one of the temperature-independent solar systems, solar collectors are mainly used to heat the tank. Only when the temperature is not high enough, heat energy is sent to the ground heat pump system where the heat pump can obtain a higher initial temperature.

According to experts, no matter what the system is, thermal storage is the core of thermal management. Manufacturers agree on how to use thermal energy. As solar collectors operate more efficiently, solar energy is sent to cold, lower storage areas. Then, the heated stored water temperature rises. As the heated water temperature rises, if the solar thermal energy does not allow the water to reach a suitable temperature, the heat pump can also be supplemented by a second heat exchange. In some system concepts, the pumping station should ensure that the required temperature is reached. However, opinions on the separation of heating from hot water systems and the co-operation of tanks at two different temperature levels are different.
