Inner water tank described in the utility model also is connected with terminal water water return pipeline, and terminal water return circulating pump is installed on the terminal water water return pipeline, and the PLC controller is connected with terminal water return circulating pump.
PLC controller described in the utility model, solar energy heating circulating pump and terminal water return circulating pump all are arranged in the control system shell.Because PLC controller, solar energy heating circulating pump and terminal water return circulating pump integrated installation are namely simple and convenient when installing and keep in repair on water tank.
Medium back flow pipeline described in the utility model, medium output pipe, cold water inlet and hot water outlet pipe are arranged in the middle heat-insulation layer, the external-connected port of the external-connected port of medium back flow pipeline, medium output pipe, the external-connected port of cold water inlet and hot water outlet pipe's external-connected port all is arranged on the outer courage top of water tank, and the medium back flow tank also is arranged on the outer courage top of water tank.
The utility model with no pressure operation press-bearing water tank also comprises electric auxiliary heating pipe, and an end of described electric auxiliary heating pipe is arranged on the inner water tank middle part, and the other end of electric auxiliary heating pipe is arranged in the control system shell.
The below of medium output pipe described in the utility model is provided with the medium firth outlet hole.
Inner water tank described in the utility model is connected with sewage draining exit, and this sewage outfalls setting is in system shell processed.
Upper temp inductive probe and temperature of lower inductive probe are installed on the inner water tank described in the utility model.
The utility model compared with prior art has the following advantages: because PLC controller, solar energy heating circulating pump and terminal water return circulating pump integrated installation are on water tank, namely simple and convenient when installing and keep in repair, effectively utilize again the effect of heat-insulation layer, reduce heat loss.When not heating, with no pressure in pipeline and the heat exchange coil is not easy to occur revealing and fault, and especially antifreeze, system run all right and life-span are long.Simple in structure, effect has reduced cost, and various parts is unified installs good looking appearance.
