The effect of invention
According to quick response phase change heat accumulator involved in the present invention, because be provided with phase-transition heat-storage layer, so when using amount of hot water is larger, water heater working, phase change heat storage material can flow through a part of heat absorption of the hot water of this invention and store (phase transition temperature of material, a little less than hot water water temperature, can be heated to the temperature be more or less the same with hot water water temperature) as latent heat of phase change.People is when using a small amount of washing hand or other purposes, the heat energy of absorption can discharge by phase change heat storage material, be the suitable warm water used by cool water heating, avoid frequently opening water heater waste a large amount of water and heat energy or have to stand icy water in winter, energy-saving and water-saving while facilitating daily life.Even if before a large amount of hot water of use, also can avoid wasting the cold water between water heater to tap in very long one section of pipeline, when hot water temperature exceedes phase transition temperature, storage heater continues heat absorption accumulation of energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed phase change heat accumulator of the present invention by reference to the accompanying drawings.
Fig. 1 is the structural representation of embodiments of the invention 100.
Quick response phase change heat accumulator 100, is set on the outer wall of the water pipe of water outlet of water heater mouth to the fire hose draught animals close to the pipeline 4 sections of the fire hose draught animals, comprises phase-transition heat-storage layer 1, heat-insulation layer 2 and housing 3.Phase-transition heat-storage layer 1 wraps up the outer wall of water pipe line 4, for keeping certain temperature to the current in water pipe line section; Heat-insulation layer 2 wraps up phase-transition heat-storage layer 1, dissipates to phase-transition heat-storage layer external environment condition for stoping heat; And housing 3 wraps up heat-insulation layer 2, housing and water pipe line share axis, damage in a humidity environment for preventing equipment.
Housing 3 can adopt anticorrosive (as stainless steel material) to be prepared from, to prevent device damage under the working environment of humidity.Heat-insulation layer 2 can adopt insulation picture to mould plate.Insulation picture moulds the plate coefficient of heat transfer lower than 0.034W/ (km), both can reduce the heat radiation of storage heater and external environment condition, have certain compensating action simultaneously to the Volume Changes of phase-change material.Phase-transition heat-storage layer 3 can be the mixture of water and phase-change material capsule, and wherein phase-transition heat-storage microcapsules can be the microcapsules of 21-alkane (phase transition temperature is 41-42 DEG C).When water and phase-change material capsule proportioning are 1:1, phase-transition heat-storage layer 3 can reach best heat transfer rate, realizes the object of quick accumulation of heat.In storage heater running, phase-change material meeting expanded by heating, so can reserve the space of a small amount of expansion when filling.Household water pipe 4 material is preferably copper pipe, and specification is 2 points or 3 points of thin copper pipes, and namely wall thickness is 0.4mm, when pressure and water temperature all little, tube wall is thinner, and thermal resistance is less, and heat exchange rate is larger; It is good that copper pipe external diameter is about 14mm.
Embodiment one
Choosing stainless steel is that accumulator housing seals and corrosion resistant effect to reach, and working region length 272mm, outside diameter d=100mm, insulation material that inwall pastes is insulation rubber and plastic boards, and thickness is 20mm.After measuring and installing rubber and plastic boards additional, volume is 0.926L.The selection of material to be phase transition temperature the be 21-alkane of 41-42 DEG C, latent heat of phase change is 120KJ/KG, density 0.79g/cm3.Proportionally add water and phase-change material, after reserving expanded by heating space, accumulator and pipeline are completed according to design and assembly.
Through experimental test, in this storage heater, phase-change material needs the time of about 7-8 minute to heat through overtesting to reach more than 42 DEG C and complete phase transformation, thus heating cold water, this heat time can use for a long time during hot water at us reach completely.Phase-change material carries out the experiment of exothermic process after completing accumulation of heat, cold water is passed into storage heater, test storage heater water inlet, delivery port and phase-change material temperature situation over time.
Measured by experiment, when inlet water temperature lower than material phase transformation temperature 27 DEG C (inlet temperature 15 DEG C), delivery port from start to finish exceeds about 10 DEG C than inlet water temperature, and heat-storing material temperature maintains phase transition temperature, phase-change accumulation energy provides heating cold water institute energy requirement, and during low discharge, the duration can reach more than 10 minutes.Pass into winter cold water water temperature lower time, because the temperature difference is larger, according to heat transfer principle, accumulator heat exchange rate will increase, and heat exchange is more, import and export the water temperature temperature difference larger, therefore, when water pipe water temperature about 10 DEG C in winter, output water temperature still can reach more than the 20 DEG C suitable temperature used.
If by other average daily a small amount of water (as washing one's hands) of a family 15 times, when not installing of the present invention, wash one's hands at every turn and need to wait for that hot water flows out from water heater, if be 5m according to water heater to tap pipe range, internal diameter 13mm calculates, the water yield of each waste is 0.66L water, wastes the water yield every day and is about 10L; Each 250ml water consumption calculates, and a small amount of water needs heat hot water 0.91L at every turn, many consumption every day about 0.45 degree electricity.When installing of the present invention, consider the electricity needing when removing accumulation of heat to consume, monthly amount to and can save 0.3 ton, water, electricity more than 12 degree.
The effect of embodiment and effect
Quick response phase change heat accumulator involved by the present embodiment, because be provided with phase-transition heat-storage layer, so when using amount of hot water is larger, allow water heater working, phase change heat storage material can flow through a part of heat absorption of the hot water of this invention and store (phase transition temperature of material, lower than hot water water temperature, can be heated to the temperature be more or less the same with hot water water temperature) as latent heat of phase change.People is when using a small amount of washing hand or other purposes, do not need water heater working, the heat energy of absorption can discharge by phase change heat storage material, be the suitable warm water used by cool water heating, avoid frequently opening water heater waste a large amount of water and heat energy or have to stand icy water in winter, energy-saving and water-saving while facilitating daily life.Even if before a large amount of hot water of use, also can avoid wasting the cold water between water heater to tap in very long one section of pipeline, when hot water temperature exceedes phase transition temperature, storage heater continues heat absorption accumulation of energy.
Above embodiment be only the present invention conceive under basic explanation, do not limit the invention.And according to any equivalent transformation that technical scheme of the present invention is done, all belong to protection scope of the present invention.
