It is building heating to help water source heat pump system, is had to alleviating the environmental problems such as China's fossil energy exhaustion and the haze being on the rise
Very important realistic meaning.
The feasibility of solar energy Coupling Water-source Heat Pump technology has become the common recognition of numerous researchers, studies have shown that this pair is hot
On the one hand source heating technology can solve the problems, such as that heat collector area is excessive when solar energy individually heats, on the other hand can improve
Heat pump unit water at low temperature source water temperature, and then the operational energy efficiency of unit is improved, reduce the operation energy consumption of system.Single water source heat
It is ripe to pump Technical comparing, solar energy heating system also has technical specification guidance, but exists about solar energy-water source heat pump combining system
Research in terms of building heating, the especially research in terms of diurnal storage solar energy Coupling Water-source Heat Pump heating are still insufficient.
For solar energy diurnal storage, since solar energy has intermittent and the scrambling of sunshine-duration on daytime and intensity spy round the clock
Point, so the method for operation of the association system just becomes the key for improving the association system efficiency and reliability.Current solar energy
The general method of operation of Coupling Water-source Heat Pump is：While solar heat-preservation, in real time according to the exit water temperature of hot water storage tank
Different operational modes is selected, to make full use of the hot water in water tank to heat.This method of operation is effectively improved heat
The water temperature of water at low temperature source is pumped, the operational energy efficiency of heat pump unit improves therewith, to the operation energy consumption for the system of saving.But water
Hot water in case is used in real time so that the hot water mean temperature in system heating process in hot water storage tank cannot fill
Divide and improve, causes the time that the hot water in water tank is used directly to heating shorter, or the temperature of direct-furnish is not achieved at all, thus heat
Pump assembly needs prolonged booting heating.This method of operation seems can utilize solar energy in time, but be sent out by studying
Now since the advantage of solar energy direct heating cannot be made full use of, thus the operation energy of system can not be improved to the maximum extent
Effect.
