Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
nullBy Fig. 1、2、Shown in 3，A kind of geothermal step is provided multiple forms of energy to complement each other and is utilized control system，Including central control system，Central control system connects end energy supply control system by communication network、Plate changes cyclic control system、Heat pump energy supply control system and domestic hot-water's water management system，Described end control system is used for detecting the end supply backwater pipe temperature difference，And by converter regulation plate type heat exchanger and the feed pump frequency of absorption heat pump，Described plate changes cyclic control system and changes supply backwater temperature difference for detecting plate，When detecting that plate type heat exchanger supply water temperature cannot meet end functional requirement，Circulating pump frequency by converter regulation plate type heat exchanger，And by energy supply control system control absorption heat pump end is carried out supplement energy supply，Described domestic hot-water's water management system is used for detecting domestic hot-water for backwater pressure reduction，When heat pump energy supply deficiency being detected，End energy supply is supplemented by converter regulation domestic hot-water's feed pump.
As in figure 2 it is shown, be energy supply in winter, system is by exploiting deep geothermal heat, and GEOTHERMAL WATER distribution supplies heat exchanger one and absorption heat pump generator.Heat exchanger one realizes heat exchange, it is achieved the direct heating to end-equipment.GEOTHERMAL WATER after heat exchange, then to heat exchanger two, heat energy is supplied absorption heat pump vaporizer, it is achieved the heat supply to end-equipment, the GEOTHERMAL WATER water outlet of supply absorption heat pump generator is connected to thermal water, and heat exchanger three water inlet supplements.Heat energy, to heat exchanger three, is supplied domestic hot-water's pipe, is heated by tap water by heat exchanger two water outlet.Tap water after heating leads to solar water heater again, it is achieved again heat, and reaches heat supply temperature, and by thermal storage device, savings supply user uses.Meanwhile, the hot water in thermal storage device realizes supplementing supplying hot water.Native system realizes making full use of geothermal energy and energy-saving effect.
As it is shown on figure 3, be energy supply in summer, GEOTHERMAL WATER, by exploiting deep geothermal heat, is being respectively supplied to absorption heat pump generator and heat exchanger three by system, and the side water outlet of absorption heat pump generator is to hot spring；High-temperature water is also supplied with hot spring through heat exchanger three heat exchange, and tap water is connected to heat exchanger three by running water pipe, the tap water after heat exchange, heat through solar water heater, by hot water storage, supply user, hot water supply absorption type heat pump assembly generator simultaneously, carries out concurrent heating.
Being additionally provided with ancillary heating equipment in system, ancillary heating equipment is to the tap water heating after heat exchanger three heat exchange, and ancillary heating equipment is preferably by electrical heating, it is achieved no pollution.
In order to implement the control to regional, at end supply backwater pipe, temperature sensor is set, at the confession return pipe of plate type heat exchanger, temperature sensor is set, supply to arrange pressure transducer at return pipe domestic hot-water, such as Fig. 4, the temperature difference of end control system detection end supply backwater pipe, when the temperature difference requires less than setting, plate type heat exchanger feed pump frequency is regulated by converter, end is made to supply more hot water, improve the heat supply of end, if still can not be met the setting requirement of the temperature difference by regulation feed pump frequency, then show that the heat energy that heat exchanger one provides cannot meet energy supply requirement, feed pump frequency now by regulation absorption heat pump carries out concurrent heating.
Such as Fig. 5, plate changes the energy supply control system detection plate type heat exchanger temperature difference for return pipe, when the temperature difference requires less than setting, circulating pump frequency by converter regulation plate type heat exchanger, mainly improve the frequency of plate type heat exchanger primary side feed pump, if temperature difference requirement can not be met circulate regulation the most always.Such as Fig. 6, when the end supply backwater pipe temperature difference is less than setting value, first pass through end energy supply control system regulation plate type heat exchanger feed pump frequency, end is made to supply more hot water, improve the heat supply of end, if still can not be met the setting requirement of the temperature difference by regulation feed pump frequency, then show that the heat energy that heat exchanger one provides cannot meet energy supply requirement, control absorption heat pump now by energy supply control system and carry out end supplementing energy supply.Such as Fig. 7, domestic hot-water's control system detection domestic hot-water is for backwater pressure reduction, when pressure reduction is less than setting value, shows under-supply to domestic hot-water of heat pump, regulates feed pump frequency by converter, improve heat supply frequency.
