1. energy storage pattern
The utility model energy-storage system 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 determine 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.Suitable earth surface water source is arranged or manually be built into the earth's surface tank around the building.
Winter: by the cold-zone water circulating pump near low temperature surface water cycle is passed through the cold pipe laying nest of tubes of storage, so that cold is stored in the nest of tubes soil on every side.When selecting simultaneously cold day, cutting earth's surface water surface ice sheet is stored up in ice storage pond 4, specifically decides on the pond volume.Finish the rear surface and build, be incubated coated with straw, stalk, soil layer etc.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 upward reduces largely simultaneously pond body peripheral temperature, so that loss of refrigeration capacity reduces in the ice storage pond.Concrete mode is: are connected with the cold-zone water circulating pump surface water body is connected connections with Chu Leng pipe laying nest of tubes by opening storage cold-zone outlet valve 37, surface-water inlet valve 38, surface water outlet valve 36, realize storing up cold winter; 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 larger in addition, can consider to adopt phase-change material such as (paraffin etc.) as heat-storage medium.Concrete mode is: by 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 the underground pipe heat accumulation.Simultaneously unlatching storage wax 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 to a great extent the operational efficiency of air-conditioning unit, reach the purpose of power saving.The specific embodiment is: by 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 interior water temperatures in ice storage pond 4 raise can not satisfy the cooling demand time, 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, rely on the cold pipe laying nest of tubes 9 of storage to be connected connections with the wind dish, implement to store up the direct cooling of cold nest of tubes.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, finish earth source heat pump unit cooling.
