The technical scheme of the utility model: a kind of concentrated collection heat separating user heat-accumulation solar system; Comprise solar thermal collector group, expansion tank, circulating pump; Described solar thermal collector group connects thermal-arrest major cycle pipe and thermal-arrest backwater circulation pipe more than one group through circulating pump; Thermal-arrest major cycle pipe and thermal-arrest backwater circulation pipe are communicated with the inner heat exchange coil of each household water tank; Several minutes family heat-exchanging water tank that is connected in parallel between every group of thermal-arrest major cycle pipe and the thermal-arrest backwater circulation pipe, expansion tank is located on thermal-arrest major cycle pipe or the thermal-arrest backwater circulation pipe, and the family heat-exchanging water tank was provided with cold water inlet and hot water outlet in said minute; The branch pipeline that described thermal-arrest major cycle Guan Yufen family heat-exchanging water tank links to each other is provided with magnetic valve; Branch family temperature sensor T1 is set on the thermal-arrest major cycle pipe; Heat-exchanging water tank top, branch family is provided with temperature sensor T3; The bottom is provided with temperature sensor T2, and magnetic valve, temperature sensor T3 and temperature sensor T2 are connected to branch family controller respectively.When the temperature T of major cycle pipe 1 and water tank bottom temperature T 2 temperature difference are higher than 8 when spending, the controller opens magnetic valve, heat-exchanging water tank interior heat exchange coil and major circulatory system in branchs family begins heat exchange, when being lower than 4 when spending, closes magnetic valve.
Preferably, described thermal-arrest backwater circulation pipe comprises thermal-arrest return pipe and heat exchange return pipe, and thermal-arrest return pipe bottom and heat exchange return pipe bottom are connected, and the heat exchange return pipe is communicated with the inner heat exchange coil of each household heat-exchanging water tank.
Preferably, described solar energy system also is provided with long distance control system, and temperature sensor T1, circulating pump, temperature sensor T2, magnetic valve and temperature sensor T3 are connected to long distance control system respectively.
Preferably, described solar energy system also is provided with the gas furnace assisted heating device, and each gas furnace assisted heating device is connected with heat exchange coil through pump with branch family heat-exchanging water tank.
Preferably, said minute family heat-exchanging water tank is the 120L water tank.
Should concentrate collection heat separating user heat-accumulation solar system to control through dual mode.
Control mode one: temperature difference cyclic control system, when the temperature difference (being T1-T3 or T1-T2) when spending greater than 10, the solar energy circulating pump starts, and when the temperature difference is lower than 4 when spending, the solar energy circulating pump stops.In addition, gas furnace fully guarantees the requirement of whole day hot water as assisted heating device.
Control mode two: the constant temperature cyclic control system, when being higher than 55, solar thermal collector group thermal-arrest plate temperature spends, and circulating pump is started working, and spends when temperature is lower than 50, and circulating pump quits work.Such control can utilize effective solar energy temperature to greatest extent, and solar heat is sent in each tame heat-exchanging water tank.
The beneficial effect of the utility model is: this concentrate collection heat separating user heat-accumulation solar system not only energy-conservation, be convenient to management, but also possess functions such as " antitheft heat ", anti-overheated and water tank high temperature protection.
