Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present utility model;
Fig. 2 is a kind of structure chart of heating and energy storage module;
To be described in further detail the utility model by example below.
Detailed description of the invention
As shown in Figure 1,1 in figure is Storage Unit shell, and 2 is insulation materials, 3 is external agency passages, and 4 is dividing plates, and 5 is interior media passages, 6 is heating element heaters, and 7 is infra-red electromagnetic energy storage modules, and 8 is media drives, 9 is medium circulation passages, and 10 is filters, and 11 is heat exchangers, 12 is heated medium passages, 13 is service cables of heating element heater, and TE101-103 is energy storage module sensor, and TE105 is heated medium temperature sensor 14, is series compensation capacitance.The heating power supply of this example is power frequency 6.6KV, for the occasion that electric accumulation of energy heats.Here media drive 8 is adjustable speed fan, heat medium is air, heated medium is water, heating instructions is set as during being trough-electricity that 22 accumulation of energys up to zero morning 5 time, heat release instruction are from temperature sensor here, setting value at room temperature is 25 ° of C, insulation material 2 here selects aluminum silicate insulation material, heating to be heating wire, in this insulation shell 1, be provided with four infra-red electromagnetic Storage Units be made up of high temperature resistant refractory material three normally work, one for subsequent use.Distributed the heating wire be connected with 6.6KV electric network source by power supply driver in infra-red electromagnetic Storage Unit; Filter 10, heat exchanger 11, arrangements for speed regulation 8 and circulation canal 9 is also provided with outward at Storage Unit.Electric power incoming line connects one end of electric power compensation electric capacity, the load of another termination electricity energy storage equipment.
Its course of work is as follows: intelligent controller according to detect energy storage module temperature and according to setting heating the accumulation of energy time energy storage module is heated, if intelligent controller controls heating power supply driver and heats energy storage module when the temperature that this is energy storage module within this period is 900 ° of C lower than accumulation of energy desired temperature, higher than time stop heating; For having arc quenching material around heater strip, can effectively prevent arc light from causing serious harm.Can controller according to the indoor temperature of the outlet temperature detected and user when its temperature has to there is deviation with its setting value time by adjustable speed fan, the flow controlling the air heated carries out closed-loop adjustment to it.Thoroughly achieve carbonated drink separation due to what heat exchanger is arranged on Storage Unit outside, can not leak because of heat exchanger and cause connection electrical phenomena at Storage Unit.Because blower fan will cause blower fan temperature too high because of power failure in Storage Unit outside, low temperature blower fan can be used in this case to greatly reduce equipment and maintenance cost, and convenient maintenance.Because the heat exchanger front end in Storage Unit outside is provided with filter, effectively can prevent heat exchanger from blocking and fouling, be conducive to improving heat exchanger effectiveness.
Electric power compensation electric capacity is connected between high voltage source and electric energy storage equipment and plays reactive-load compensation and metering function, can effectively reduce the harm of arc light.
