With the more effective operation of solar collectors, solar energy is fed into the cold and the lower storage area, and then the temperature of the stored water increases. No matter what the system is, heat storage is the core of thermal management,heat pump manufacturer make agreements on how to use the heat. According to the investigation of the air conditioning and refrigeration markets, in the rising process of the temperature of the heated water, if the heat energy of the solar energy cannot make the water reach the appropriate temperature, then the heat pump can get the supplemental heating through a second heat exchange. In some systems concept, the pumping stations should ensure the desired temperature. But different parts hold various opinions on the separation on heating and hot water system as well as co-operation with two different temperature level of the water tank.
Technology of Solar Heat Pump
In order to prevent the solar energy, air energy and ground energy developing independently, solar energy must mach water source heat pump system in the aspects of pressure and control technology. Most suppliers try to improve the overall performance of the system by the production of solar hot water systems, and do not consider the temperature of the solar hot water system. One way is the collector transfers heat energy to the hot water or the tank in combination by a temperature-sensitive manner, just like the heat pump is used in the system of the conventional auxiliary equipment. In addition, some manufacturers also make use of the vapor of the air source heat pump or ground source heat pump and other renewable energy. It is said that make use of one of the two operation system which has nothing to do with the temperature, it mainly use the solar collectors to heat water tank. Only when the temperature is not high enough, the heat is fed into the heat pump to obtain a higher initial temperature of the ground heat pump system.
Conclusion of Solar Heat Pump
On the present-day market, solar water heating system is totally different from the combination of heat pump in its system technology. Vendors are committed to the idea of a variety of control and management and energy storage technology innovation. The complex energy extraction work has be initiatively found, used and completed by a professional technical team. The promotion of solar heat pump is definitely not just selling something, but promote an awareness of energy-saving, together with the ways for users to explore energy-saving.
