Abstract
The utility model discloses a cross-season soil energy storing device applied to a ground source heat pump. The cross-season soil energy storing device is mainly applied to a ground source heat pump system. The ground source heat pump comprises a summer ground source heat pump, a condenser, a winter ground source heat pump and an evaporator, wherein the summer ground source heat pump is connected with the condenser through a cooling pipeline, and the winter ground source heat pump is connected with the evaporator through a heating pipeline. The cross-season soil energy storing device further comprises a soil energy storing device body which is arranged in soil. The soil energy storing device body comprises a plurality of capillary pipe bundles. The inlet end of each capillary pipe bundle is communicated with an inlet pipe through a quick connector, the outlet end of each capillary pipe bundle is communicated with an outlet pipe through a quick connector, and the inlet pipe and the outlet pipe are both communicated with the inlet/outlet of a freezing water pipe of a heat pump machine set. The cross-season soil energy storing device uses the capillary pipe bundles to store low-grade natural energy and can release heat energy and cold energy out when the system needs heat energy or cold energy. The cross-season soil energy storing device uses cold sources and heat sources in nature and doesn't need any commercial energy except a little water pump circulating power in a process.
Description
Technical field
The utility model relates to earth source heat pump field, specifically, specially refer to a kind of be applied to earth source heat pump across soil energy storage equipment in season.
Background technology
Earth source heat pump is a kind of highly effective energy-conserving environmental-protecting type energy utilization technology that utilizes underground shallow layer geothermal energy resources.By inputting a small amount of high-grade electric energy, can realize the lifting of energy from low-grade Cooling and Heat Source to high-grade energy.Summer, can utilize the soil moisture of shallow surface lower than outdoor feature, the low-grade energy in soil is taken out, for the cooling or direct cooling (by reducing the condensation temperature of whole refrigeration system, reaching the object that improves system effectiveness) of condenser; And in winter, utilize the soil moisture of shallow surface higher than outdoor feature, low grade heat energy in soil is taken out, for in the evaporation or direct heating clamber of evaporimeter (by improving the evaporating temperature of whole refrigeration system, reaching the object that improves system effectiveness).
But at this, from shallow surface, extract low-grade energy, then recharge the way in soil, at the long-term Soil Temperature Field that causes in service of system, can not get effective recovery, evaporating temperature and condensation temperature fluctuation are larger, and earth source heat pump unit operation efficiency is declined.Simultaneously, when selecting refrigeration unit, also can be due to building self, the imbalance of cooling and heating demand, cause the problems such as the capacity of earth source heat pump unit is excessive, as: the southern area in China, building required refrigeration duty in summer will be much larger than required thermic load in winter, during according to refrigeration duty selection in summer unit, the heating capacity of considering source pump is on the basis of 1.1-1.3 times of refrigerating capacity, can cause heating capacity well beyond thermic load requirement in winter, make power system capacity excessive, cause waste; And for the large the northern area of China of winter cold and thermic load, utilize separately soil source heat pump system, and can cause winter heat-obtaining superfluous and make underground temperature reduced year by year, affect the efficiency of heat pump.
Utility model content
The technical problem that the utility model actual needs solves is: for deficiency of the prior art, provide a kind of be applied to earth source heat pump across soil energy storage equipment in season, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Be applied to earth source heat pump across soil energy storage equipment in season, comprise earth-source hot-pump system, described earth-source hot-pump system have summer earth source heat pump and condenser, winter earth source heat pump and evaporimeter; Described summer, earth source heat pump was connected with condenser by cooling pipeline, winter, earth source heat pump was connected with evaporimeter by intensification pipeline, in described cooling pipeline and intensification pipeline, all have for conducting the liquid medium of heat, also comprise soil energy storage equipment, described soil energy storage equipment is arranged in soil, it comprises some capillary groups, the arrival end of described capillary group all adopts quick union to be communicated with inlet tube, the port of export of capillary group all adopts quick union to be communicated with outlet, and described inlet tube and outlet are imported and exported and are communicated with the chilled water of source pump respectively.
Further, described some capillary groups layer-stepping is from top to bottom distributed in soil.
Compared with prior art, the beneficial effects of the utility model are as follows:
Adopt microcapillary tube group, low-grade natural energy is stored, then when system needs, heat energy, cold are discharged.Be characterized in across season cold accumulation system be the cold and heat source that utilizes the Nature, remove outside water pump circulation merit a small amount of in process, without any commercial energy.
Accompanying drawing explanation
