Applied Study On Coastal Solar Pond Heat Pump Technology

Due to lack of energy resoucre,the exploitation and utilization of renewable energy have been strategic measures in all around the world.As a clean and permanent energy resource, the solar energy has been generally recognized.Solar Pond,a kind of unique saline pond,has abailiy to collect and store solar energy,with provides the reliable low temperature heat source hotly for each kind,in recent years caused various countries widely to take seriously and to study.The coastal sun pond heat pump technology is provides for pump technology from the air and which salty gradient sun pond takes low position heat source as the low temperature heat source,it's one kind may switch double heat source sun pond heat pump pattern:When the ambient temperature is high,heat pump air source movement;When the ambient temperature reduces to under 7℃,the switch is the water source movement,the low temperature hot water is from the solar pond extraction the quantity of heat.This article made the following work to the non-convection sea water sun pond heat pump system:1.This article regard on the sun pond's heat transfer process as one-dimensional,unsteady, with a heat source within the heat transfer problem,finite difference method of application, simulate solar pond thermal performance of the numerical.2.Has completed the solar pond transient state behavior one-dimensional numerical simulation work,simulated 10000m~2 salt gradient sun pond to withdraw the 20W/m~2 pond bottom the temperature change.explanation can provide a stable and reliable low-temperature heat source to heat pump.3.Discusse influence on the sun pond the thermal performance of the main factors, focused on the non-troposphere of the sun pond to withdraw heat.4.Has established the double heat source sun pond heat pump system,and proposed the coastal area system's movement strategy,as well as in view of Dalian City actual usable area is 300 m~2 building double heat source heat pump's analog computation.5.Analysis on the stability of the solar pond heat pump system,energy saving, environmental protection,and compare flat-type collector and coal-fired boilers to economy, demonstrate the highlights the superiority of sun pond heat pump.
