Abstract
The utility model relates to a geothermal heat exchange system automatically recharging to accumulate cold energy, comprising a U-shaped heat exchange tube composed of a plurality of tube sections buried underground, and a plurality of heat rods, wherein each heat rod is cylindrical and composed of a condenser located on the ground, a middle heat-isolating section buried underground, an evaporator with a cylindrical end part, and a low-boiling-point working medium filled in the heat rod tube sections; and the heat rods are disposed around the U-shaped heat exchange tube. The geothermal heat exchange system automatically recharging to accumulate cold energy disclosed by the utility model has the following advantages that: a natural cold energy in the atmosphere is transmitted to the U-shaped heat exchange tube area via the thermal diode characteristic of transferring heat unidirectionally of the heat rod when the temperature of the U-shaped heat exchange tube area is higher than an environmental temperature in the winter, so that the temperature of the area is decreased to accumulate the cold energy for being used in the following summer. The heat rods in the utility model have no need to add a new energy, so that the investment and operation costs are low, and a ground-source air conditioner is ensured to run in the condition of a high efficiency in the coming year.
Description
Technical field:
The utility model relates to a kind of air-conditioning technique, can heat-exchange system more specifically to a kind of ground that recharges the savings cold automatically.
Background technology:
Earth-source hot-pump system is to be the air-conditioning technical of tool development prospect of characteristic with energy-conservation and environmental protection, and vertical-pipe heat exchanger is the core of earth source heat pump, is that the cold and heat source of earth source heat pump obtains the efficient place.Yet,, be distinguishing for the utilization of ground ability or because of area or demand because of producing; For example, in major part manufacturing type factory, because machinery equipment can be generated heat or owing to use firing equipment; Need refrigeration summer, then do not need heating winter, uses ground energy air conditioner in this case; Can cause depths, face of land temperature to raise gradually, the efficient of air conditioner refrigerating is reduced.The reason that analysis causes depths, face of land temperature to raise gradually is: when the summer air-conditioning system moves; The medium that central air-conditioning was done merit gets into the U type ground pipe laying of imbedding depths, the face of land; Carry out heat handing-over fully with underground; Make the temperature of medium remain on basically about 17 ℃, meanwhile the temperature in the territory, the buried area under control of U type of depths, the face of land also raises gradually, but central air-conditioning does not have running in the winter time; This part thermal source accumulates in the territory, the buried area under control of U type of depths, the face of land and is difficult to leave, and makes the efficient of air conditioner refrigerating in the coming year reduce.Therefore, when not using ground energy air conditioner in the winter time, how airborne cold being recharged and be stored into depths, the face of land, as the compensation of the cold of system, use when supplying summer and freezing, is a problem that is worth research.
The utility model content:
The purpose of the utility model be provide to the prior art weak point a kind of simple in structure, cheaply, the ground that recharges the savings cold automatically that improves the efficient of air conditioner refrigerating can heat-exchange system.
The purpose of the utility model is to realize through following measure: a kind of ground ability heat-exchange system of recharging the savings cold automatically, and it has the U type heat exchanger tube of the some pipeline sections compositions that bury ground, it is characterized in that also having some hot pins; Said hot pin is column, and it is made up of the condenser that is positioned at ground, the evaporimeter that is embedded in underground middle adiabatic section, cylindrical end, the low boiling working fluid that is filled in the hot pin pipeline section, said hot pin be arranged on U type heat exchanger tube around.
Compared with prior art; The ground ability heat-exchange system of recharging the savings cold automatically that the utility model proposes; Has following advantage: utilize the thermal diode characteristic of the unidirectional heat transfer of hot pin, when the temperature in U type heat exchanger tube zone is higher than environment temperature in the winter time, the natural cold-energy in the atmosphere is transferred to U type heat exchanger tube zone; Make this regional temperature reduce the savings cold energy, use the summer of waiting for the coming year; Hot pin quit work when the temperature in U type heat exchanger tube zone was higher than environment temperature when summer, can the heat in the surrounding air be delivered to U type heat exchanger tube zone.The hot pin of the utility model need not to increase the new energy, and investment and operating cost are low, guarantee that earth source air conditioner turns round under high efficiency situation the coming year.
Description of drawings:
Fig. 1 is the system schematic of an embodiment of the utility model proposition.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1 has provided the system diagram of the utility model embodiment.Among the figure, a kind of ground ability heat-exchange system of recharging the savings cold automatically, it has: bury the U type heat exchanger tube 1 of some pipeline sections compositions on ground, some hot pins 2; Said hot pin is column, and it is made up of the condenser that is positioned at ground 21, the evaporimeter 23 that is embedded in underground middle adiabatic section 22, cylindrical end, 24 of low boiling working fluids that are filled in the hot pin pipeline section, said hot pin 2 be arranged on U type heat exchanger tube around.
The hot pin operation principle that the utility model adopts is: hot pin can conduct heat in the scope of the little temperature difference; When the soil moisture around the evaporator section is higher than environment temperature; Utilize the low boiling working fluid vapour-liquid two phase transformation convection circulations in the hot pin; Natural cold-energy in the atmosphere is transferred in the soil of environment, when the soil moisture around the evaporator section is lower than environment temperature, hot pin will not worked.The utility model whole system is work like this: during summer; The U type heat exchanger tube zone of burying ground passes to the medium in the U type heat exchange tube with cold energy; Medium is taken back cold energy and is returned central air conditioning, and this moment, the soil moisture around the hot pin evaporator section is lower than environment temperature; Hot pin is in off position, does not influence the work of central air conditioning.When after winter; The soil moisture around the hot pin evaporator section is higher than environment temperature; Utilize the low boiling working fluid vapour-liquid two phase transformation convection circulations in the hot pin, the natural cold-energy in the atmosphere is transferred in the soil of environment, progressively reduce U type heat exchanger tube zone temperature on every side; In U type heat exchanger tube zone, use the summer of preparing next year with the savings of the natural cold-energy in the atmosphere.
The foregoing description does not constitute the restriction to the utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the utility model.
