Description
Technical field:
The present invention relates to heating and refrigeration system technical field, be specifically related to a kind of for the automatic compensation group control system for ground source heat pump of self compensating system for cold and hot deficiency.
Background technology:
Earth source heat pump be a kind of solar energy resources utilizing the earth to store as Cooling and Heat Source, carry out the heating refrigeration air-conditioning system of power conversion.A kind of technology of clean regenerative resource that what earth source heat pump utilized is, surface soil and water body are huge solar thermal collectors, have collected the solar radiation energy of 47%, (water body of underground indirectly accepts solar radiation energy by soil) more than 500 times of the annual utilization of the mankind; It is again simultaneously a huge dynamic power balance sysmte, and the soil and water on earth's surface keeps energy accept and disperse relative balance naturally, and the success of ground source heat pump technology makes to utilize the almost limitless solar energy that is stored in wherein or ground to become a reality.During earth source heat pump unit operation, do not consume water also not contaminant water, do not need boiler, do not need cooling tower, also do not need the place of stacking fuel exhaust, environmental benefit is remarkable.The power consumption of earth source heat pump unit, also can reduce more than 40% compared with air source heat pump; Can reduce more than 70% compared with heating with electricity, its heating on average improves nearly 50% than the efficiency of gas fired-boiler, has exceeded 75% than the efficiency of gas fired-boiler.
Heat pump unit device mainly contains: compressor, condenser, evaporimeter and expansion valve four part composition, constantly complete by allowing liquid refrigerant (cold-producing medium or refrigerant): the thermodynamic cycle process of evaporation (draw heat in environment) → compression → condensation (releasing heat) → throttling → evaporate again, thus by the transfer of heat in environment in water.Compressor (Compressor): play a part compression and delivery cycle working medium from low-temp low-pressure to HTHP place, be the heart of heat pump (refrigeration) system; Evaporimeter (Evaporator): be the equipment exporting cold, its effect is the refrigerant liquid evacuator body making to flow into through choke valve, to absorb the heat of cooled object, reaches the object of refrigeration; Condenser (Condenser): the equipment being quantity of heat given up, the heat that the heat absorbed from evaporimeter transforms together with compressor consumed work within the condenser cooled medium is taken away, and reaches the object heated; Expansion valve (ExpansionValve) or choke valve (Throttle): reducing pressure by regulating flow effect is played to cycle fluid, and regulate the cycle fluid flow entering evaporimeter.According to the second law of thermodynamics, the merit (electric energy) that compressor consumes plays compensating action, and cycle fluid is constantly absorbed heat from low temperature environment, and to hot environment heat release, week and reciprocally circulating.
Although ground source heat pump technology has many benefits, but in actual motion, run into the operating mode that soil is extremely cold or very hot, Normal practice increases attached cold and hot equipment, add the capacity of large equipment, thus make equipment surplus excessive, often bring the increase of initial investment and the low problem of utilization rate of equipment and installations, or the primary demand of system cloud gray model can not be met at all.
Chinese patent ZL201020117950.X discloses one " energy compensating system of ground source heat pump central air conditioner ", by arranging plate type heat exchanger in thermal cycle system, the water inlet end of described plate type heat exchanger is respectively by the evaporator bank in pipeline connection thermal cycle system and the Intranet water knockout drum in the Intranet circulatory system, and the water outlet end of described plate type heat exchanger is respectively by the ground source circulating pump group in pipeline connection thermal cycle system and the Intranet water collector in the Intranet circulatory system.Such scheme just by connecting a heat exchanger on original basis, just can effectively solve because the underground pipe quantity under original place existing for heating system is few, or due to the reduction of long-play heat exchange efficiency, cause the problem of underground pipe system low side heat energy deficiency.Although can compensate by heat exchanger the problem that the system caused because soil is extremely cold supplies thermal output deficiency, but cannot solve for the problem causing thermal cycle cooling system effect to decline that rises because of the soil moisture, and this bucking-out system adopts control manually completely, automatically dynamic compensation can not be carried out to system mode, therefore there is certain hysteresis quality in its compensation effect, and effect is unsatisfactory.
Summary of the invention:
