Fig. 6 is the working principle schematic representation of energy lift device when freezing summer in the utility model geothermal liquid cold and hot source device.

As shown in Figure 1, geothermal liquid cold and hot source device of the present utility model comprises accumulator 20, liquid sorption pump 60, energy lift device 10, Pump for giving-out 50 and the heater 70 that is linked together by pipeline.Wherein accumulator 20 places undergroundly, and its drain pipe 120 links to each other with liquid return pipe with the liquid inlet pipe of energy lift device 10 with heater 70 through liquid sorption pump 60 respectively with liquid return pipe 12b.The drain pipe 102 of energy lift device 10 is through Pump for giving-out 50 and the cold and hot place's (being load) that needs, link to each other as the air conditioner (not shown), the liquid return pipe 103 of air conditioner with the condenser 2 of the energy lift device 10 liquid inlet pipe 2b of the heat exchange pipe of the coupling (see figure 5) that links to each other mutually.

Extremely shown in Figure 4 as Fig. 2, accumulator 20 comprises storage body 21, places the several layers that is staggered stacking in the storage body 21 to be filled with phase change material, as the accumulation of energy tube 22 of water, glycerine, salt solution or ethanol, place the last homogenizing plate 23 on the upper strata accumulation of energy tube and place the dunnage with uniform through hole 24 under lower floor's accumulation of energy tube with uniform through hole, and the top formation liquid-inlet 25 of last homogenizing plate 23 and storage body, the following formation liquid outlet 26 of dunnage 24 and storage body.Six heat exchanger surfaces of storage body 61 have some radiating fin 28 (see figure 1)s that Mi Zixing is arranged that are.The two ends of each accumulation of energy tube 22 have the convex shoulder that forms the slit of flowing for liquid between the accumulation of energy tube, and wherein accumulation of energy tube 22 can be made by the plastics of high-strength corrosion-resistant erosion.Convex shoulder 27 makes between the accumulation of energy tube 22 and produces the slit, thereby guarantees that liquid flows around the accumulation of energy tube.Liquid stores to energy transfer the accumulation of energy tube in flow process.When liquid needs energy, center on flowing of accumulation of energy tube by liquid, the accumulation of energy tube passes to liquid to energy again.Thereby make the accumulation of energy tube reach the purpose that stores and release energy.

Accumulator preferably places underground because underground be a zone of constant temperature that temperature variation is little.The band cool in summer and warm in winter that just is commonly called as.Accumulator places underground, the heat exchange in accumulator between working fluid and the accumulation of energy tube, also has the heat exchange of accumulator and underground zone of constant temperature.Summer, passed to accumulator to heat winter the cold accumulator of passing to.

Another important feature of accumulator is a phase-changing energy-storing.With water is example, and the phase transition temperature of water is 0 ℃, and water is 1m when liquid state ³Coolant-temperature gage raises or reduces by 1 ℃ of energy requirement 1kwh/ ℃ m ³When undergoing phase transition, 0 ℃ water becomes 48.4kwh/ ℃ of m of ice energy requirement of 0 ℃ ³, just water when undergoing phase transition for 0 ℃, 1m ³The available energy of water is 48.4kwh/ ℃ of m ³

10 ℃ of basically identicals of buried in the winter time accumulator and subsurface temperature.Calculate accumulator energy stored now.Suppose that working fluid is 1m in the accumulator ³, liquid is 2m in the accumulation of energy tube ³, liquid volume is 2+1=3m ³Being reduced to 0 ℃ show off one's talent or competence is 3 * 10 ℃=30kwh.Accumulation of energy was 2 * 48.4kwh=96.8kwh when liquid underwent phase transition in the accumulation of energy tube.Accumulator is accumulation of energy 30+96.8=126.8kwh altogether.Per hour need to be 10KW as liquid cold and hot source, but the accumulator energizing quantity time is: 126.8kwh/10W=12.68h, just liquid cold and hot source institute energy requirement can be provided under adiabatic state is 12.68h to accumulator.

Summer, subsurface temperature was 15 ℃, and exothermic temperature is 50 ℃, and the temperature difference is 50 ℃-15 ℃=35 ℃, and the cooling accumulation of energy is 1kwh/ ℃ of m altogether ³* 35 ℃ * 3m ³=105kwh, the 10kw that per hour consumes energy, can solve the cooling time is 105kwh/10kw=10.5h, this is the situation under the adiabatic state.If consider the heat exchange of underground zone of constant temperature and accumulator, actual value is far longer than this value.
