Described automatic control system 4 comprises: automatic control signal output blocks such as temperature sensor in each distribution and collecting system, hold over system and the hot-water heating system and blower fan, water pump.
For six kinds of different working conditions of system, combine accompanying drawing to explain respectively at present.
During the accumulation of heat operating mode, Open valve 18,21, valve-off 19,20, indoor air outlet 15,17 is closed, and exhaust outlet 16 outside the opening chamber.System is from indoor exhausting like this, after the heat collector heating, evenly sends into the inner heating of recuperation layer cobble bed, and the Cryogenic air of oozing out through the cobble bed is drained into outdoor, does not get into the interior of building heating.This operating mode is applicable to and did not also get into before heating season; Building does not still need heating; Can come to be heating on the horizon season storing heat this moment through accumulation of heat, is because indoor temperature is high than outdoor temperature relatively from the purpose of indoor exhausting, after the heat collector heating, can obtain higher temperature.
Directly under building heating operating mode, Open valve 18,21, valve-off 19,20, open in indoor air port 15, and 17 close, and exhaust outlet 16 is closed.System without recuperation layer, heats and directly get into house interior after the heat collector heating from indoor exhausting.This operating mode be applicable to long-term overcast and rainy after, recuperation layer inside stores with empty calory, but when the room has heating demand and weather condition good, can directly satisfy the thermic load demand of building through this system.The method of operation of more than mentioning is full return air, if there is new wind demand in system, then can realize through control valve 19 and 18, and the air quantity of these two valves is carried out proportioning, is all occupying certain ratio in the air to guarantee new wind.
Via energy storage bed under building heating operating mode, Open valve 18,21, valve-off 19,20, open in indoor air port 17,15 close, exhaust outlet 16 is closed.System evenly heats cobble in energy storage bed through the ground cage from indoor exhausting after the heat collector heating, after oozing out from energy storage bed inside, arrive the air layer on boulder bed top, gets into indoor heating then.This operating mode is applicable to the heating under the normal condition, and promptly weather is good, has certain heat and user that the heating demand is arranged in the energy storage bed.The method of operation of more than mentioning is full return air, if there is new wind demand in system, then can realize through control valve 18 and 19, and the air quantity of these two valves is carried out proportioning, is all occupying certain ratio in the air to guarantee new wind.
Non-heating season is moistureproof, remove under the mould operating mode, Open valve 19,21, and valve-off 18,20, the air port 15,17 close chamber in, unlatching exhaust outlet 16.System, is evenly delivered in the accumulation of heat boulder bed energy storage bed is carried out protection against the tide and removes mould after the heat collector heating from the new wind of outdoor extraction.This operating mode is mainly used in non-heating season; Because the energy storage bed most of the time is not in running order in non-heating season; Therefore inside may produce moisture and moisture, grows mould therefrom, influences the living environment and the health of building; Cobble in the recuperation layer is carried out protection against the tide and removes mould is necessary, also is necessary.All extract outdoor new wind during the work of this operating mode, the hot humid air that oozes out through boulder bed all drains into outdoor, must not inlet chamber in.
Under the auxiliary thermal source heating operating mode, system closing, promptly blower fan is shut down, and water pump is shut down, and auxiliary thermal source is started working.But this operating mode is applicable in the bad and energy storage bed of weather condition the empty calory time spent.
Under the hot water operating mode, the mode of operation of this system has two kinds, respectively to heating season and non-heating season.When system is in heating during season, no matter work in which kind of operating mode, as long as collecting system can be opened water pump in work, drive the water circulation and be heated.When system is in non-heating season, because building has not needed heating, so valve-off 18,19 and 21, Open valve 20 can be realized air in the inner circulation of heat collector, and is better, more efficiently the recirculated water in the heating heat exchanger.
With respect to the hot-water heating heating system of current application, this solar-heating heating system need not to consider leakproof, antifreeze, need not to install additional indoor heat transmission equipment, has reduced the cost of solar heating, but and high-efficient automatic operation.
