1. energy storage pattern
Energy-storage system of the present invention utilizes the pond body to cooperate the pipe laying nest of tubes to carry out heat accumulation and Chu Leng.The pond body can adopt fragment of brick cement to build.Pond volume, pipe laying depth confirm that according to customer charge pond body and pipe laying nest of tubes top (contain 1 meter) far from ground more than 1 meter, and cover with insulation material 7.There are suitable earth surface water source or manual work to be built into face of land tank around the building.
Winter: through the cold-zone water circulating pump near low temperature surface water is cycled through the cold pipe laying nest of tubes of storage, make cold be stored in the nest of tubes soil on every side.When selecting cold day simultaneously, cutting face of land water surface ice sheet is stored up in ice storage pond 4, specifically looks the pond volume and decides.Build on the surface after accomplishing, and covers with straw, stalk, soil layer etc. to be incubated.The cold pipe laying nest of tubes of storage around the ice storage pond plays the effect that stores cold on the one hand, also goes up largely simultaneously and reduces pond body peripheral temperature, makes that loss of refrigeration capacity reduces in the ice storage pond.Concrete mode is: surface water body is connected with Chu Leng pipe laying nest of tubes 9 with cold-zone water circulating pump 51 through unlatching storage cold-zone outlet valve 37, surface-water inlet valve 38, surface water outlet valve 36, realizes that the storage in winter is cold; Employing machinery is got the ice mode, gets ice sheet or other ice cubes source on the surface water body, puts to be stored in the ice storage pond 4.
Summer: utilize solar thermal collector 6, cooperate storage wax pond 5 and heat accumulation pipe laying nest of tubes 8, carry out the heat accumulation in summer.The solar radiation in summer is very strong, and heat is sufficient, collects the higher hot water of hot quality as far as possible and carries out the pipe laying storage; Consider that water is as heat-storage medium; Storage capacity is less, and excessively season, heat waste was bigger in addition, can consider to adopt phase-change material such as (paraffin etc.) as heat-storage medium.Concrete mode is: through the unlatching of thermal-arrest outlet valve 93, thermal-arrest inlet valve 97, heat accumulation district inlet valve 98 and hot-zone water circulating pump 54, solar thermal collection system 6, heat accumulation pipe laying nest of tubes 8 are connected, realize ground pipe laying heat accumulation.The wax of unlatching storage simultaneously pond inlet valve 94, storage wax pond outlet valve 95, heat accumulation district outlet valve 96 can realize storing up wax pond 5 and 8 while of heat accumulation pipe laying nest of tubes heat accumulation.Close heat accumulation district inlet valve 98, then only realize storage wax pond 5 heat accumulations.
2. energy supply pattern:
In summer, the cold that at first utilizes ice storage pond 4 to obtain takes the direct-furnish mode to satisfy user's cooling demand; Along with temperature increase gradually and with consuming; After ice body melted, water temperature uprised and can not reach with can demand the time, can use the cold pipe laying nest of tubes 7 of storage store up cold.When the two all can not meet the demands, can start source pump 3, it is cooperated with the cold pipe laying nest of tubes 7 of storage, give the building cooling.At this moment, the pipe laying nest of tubes hold cold and the cold surplus in ice pond, can improve the operational efficiency of air-conditioning unit to a great extent, reach purpose of power saving.The specific embodiment is: through the unlatching of direct-furnish cold side outlet valve 31, direct-furnish cold side inlet valve 32, ice storage pond inlet valve 33, ice storage pond outlet valve 34 and cold-zone water circulating pump 51, ice storage pond 4 is connected with wind dish 1, realizes ice storage pond 4 direct coolings.When the water temperature rising can not be satisfied the cooling demand in the ice storage pond 4, open storage cold-zone inlet valve 35, storage cold-zone outlet valve 37, close ice storage pond inlet valve 33, ice storage pond outlet valve 34, dependence is stored up cold pipe laying nest of tubes 9 and is connected with wind dish 1, implements the direct cooling of the cold nest of tubes of storage.When the two all can not satisfy the cooling requirement, close direct-furnish cold side outlet valve 31, direct-furnish cold side inlet valve 32, storage cold-zone inlet valve 35 and cold-zone water circulating pump 51.Open terminal cooling inlet valve 61, terminal cooling outlet valve 62, source heat extraction inlet valve 63, source heat extraction outlet valve 64, end side water circulating pump 52, source water circulating pump 53 and source pump 3, accomplish earth source heat pump unit cooling.
Winter, operation method and aestival aspect with, at first take paraffin store up heat, in the time can not satisfying the indoor heating demand, use store up in the heat accumulation pipe laying nest of tubes 8 heat.When the two all can not satisfy, start source pump 3, it is cooperated with heat accumulation pipe laying nest of tubes 8, give building heat supplying.The specific embodiment is: through the unlatching of direct-furnish hot junction outlet valve 91, direct-furnish hot side inlet valve 92, storage wax pond inlet valve 94, storage wax pond outlet valve 95 and hot-zone water circulating pump 54, will store up wax pond 5 and be connected with floor heating 2, and realize storing up winter wax pond 5 direct-furnish patterns.When temperature can not satisfy heat demand in the storage wax pond 5, open heat accumulation district outlet valve 96, heat accumulation district inlet valve 98, close storage wax pond inlet valve 94, storage wax pond outlet valve 95, rely on heat accumulation pipe laying nest of tubes 8 to be connected with floor heating 2, implement heat accumulation nest of tubes direct heating.When the two all can not meet the demands, close direct-furnish hot side inlet valve 92, direct-furnish hot junction outlet valve 91 and hot-zone water circulating pump 54.Open ground source heat-obtaining inlet valve 65, source heat-obtaining outlet valve 66, terminal heat supply outlet valve 67, terminal heat supply inlet valve 68, end side water circulating pump 52, source water circulating pump 53 and source pump 3, accomplish the heat supply of earth source heat pump unit.
