Description
What the present invention relates to is a kind of domestic air-conditioning system, especially a kind of solar energy-saving conversion domestic air-conditioning system.Belong to heliotechnics and refrigeration technology field in the mechanical engineering.
Summer, solar energy density reaches 700～1000 watts every square metre, utilize solar energy to realize that air conditioner refrigerating can significantly reduce the air-conditioning power consumption undoubtedly, significant for improving the solar thermal utilization level with the using energy source structure of improving aircondition.Exploitation and application facet at solar thermal collector obtained significant progress in recent years, developed composite heat supply/air-conditioning system of utilizing the phreatic water cooling and adopting solar energy heating to combine, the suction-type lithium bromide air-conditioning system of Driven by Solar Energy and the absorption system that adopts ammonia-water conservancy project to verify.The development of absorption refrigeration technology, especially has the low right application of desorption temperature absorption working pair with zeolite-water and activated carbon-methyl alcohol etc., make the absorption refrigeration air-conditioning system of utilizing solar energy or waste heat obtain development faster, some research institutions are also once to adopting the right solar refrigeration system of different absorption working pairs to carry out report.Compare with other system, the adsorption-type solar air-conditioning refrigeration system has been broken away from the dependence to natural resources such as phreatic waters, rotary part is few, operation maintenance is convenient, consumed power not, be applicable to the wide geographic area that solar energy or residual heat resources are abundant, economy and region applicability are all very strong, but also exist not enough, as: because of solar radiation with round the clock, that season and Changes in weather cause running to exist is intermittent, problems such as cooling and performance inconsistency continuously.
The objective of the invention is to overcome deficiency of the prior art, proposed the rational allocation that a kind of storage by refrigerating capacities such as absorption chemical potential and physics sensible heats realizes the solar air-conditioner system output load, made the solar energy-saving conversion domestic air-conditioning system of system's continous-stable running.
Technical scheme of the present invention is as follows: adopt the absorption refrigeration principle, absorption working pair is to being zeolite-water or activated carbon-methyl alcohol, and these materials are all nontoxic, can not destroy atmospheric ozone layer, can guarantee the environment friendly of system works.Sunshine on daytime, adsorbent absorbed solar energy when sufficient, and the adsorbent bed temperature raises, and cold-producing medium is resolved from adsorbent, and the absorber internal pressure raises, and cold-producing medium enters condenser, condensed through the cooling medium cooling, was collected in the evaporation liquid reservoir.Night, environment temperature reduced, and adsorbent bed outwards dispels the heat, and bed temperature descends, and adsorbent begins the absorption refrigeration agent, and bed inner refrigerant pressure reduces.Cold-producing medium evaporation in the evaporation liquid reservoir produces refrigeration.The method that the evaporation liquid reservoir takes to increase refrigerant volume realizes the cold storage, and the purpose of storage cold is that the output that combines with fan coil pipe structure to cold is allocated.The cold form that the evaporation liquid reservoir stores is the physics sensible heat.The storage of chemisorbed potential realizes by resolving adsorbent bed, and the adsorbent bed after the parsing has possessed and continues the ability that absorption is freezed, and adsorbent bed suction potential is laid in, and is connected with evaporimeter to get final product absorption refrigeration in needs.This energy storage mode is compared with the sensible heat accumulation of energy, does not have the temperature difference with surrounding environment, and is easy to regulate.
The present invention is made up of solar energy solar adsorber, two of vacuum valves, condenser, evaporation liquid reservoir, fan coil, pump water inlet mouth, delivery port, solar adsorber is connected with condenser by vacuum valve again, condenser is connected with the evaporation liquid reservoir again, the evaporation liquid reservoir passes through the attached heat collector of another vacuum valve resorption as sorption channel, the evaporation liquid reservoir is when adsorbent bed cools off, can sweat cooling when being connected with adsorbent bed promptly, its refrigerating capacity is exported to air conditioner surroundings by fan coil, and solar adsorber also is connected with delivery port with water inlet respectively.Utilize the solar energy heating solar adsorber on daytime to make the cold-producing medium desorb, the vacuum valve that leads to condenser is opened and the vacuum valve that leads to solar adsorber cuts out, the cold-producing medium that desorbs is condensed into liquid state through condenser cooling medium (can be water or air) cooling and enters the evaporation liquid reservoir, like this, solar energy just is converted into the absorption potential energy of representing refrigerating capacity and stores.Evening is by cooling naturally, absorption cooling, cold-producing medium is adsorbed agent absorption by the vacuum valve that leads to solar adsorber, produce refrigeration, a cold part that produces is exported from fan coil by chilled water, another part stores in the evaporation liquid reservoir, can regulate refrigerating capacity according to actual conditions when needed.As shown in Figure 2, make the cryogen pipeline in the adsorbent bed in the solar adsorber, can utilize auxiliary thermal source heating adsorbent bed, being convenient to refrigeration system is rationally working under the operating mode, logical water quench can reclaim adsorbent bed sensible heat and heat of adsorption in pipeline in addition, thereby can be family or user hot water about 40～60 ℃ is provided.Solar adsorber after solar energy heating makes the cold-producing medium desorb, by vacuum valve and with the isolation of evaporation liquid reservoir and condenser, when the needs air conditioner refrigerating, only need open vacuum valve, and by cooling off naturally or logical water quench to solar adsorber.Adsorbent bed also can desorb is good adsorbent bed absorption potential deposit get up, realize the storage of chemisorbed potential, so that refrigeration when needed.
The present invention has substantive distinguishing features and obvious improvement, system of the present invention is reliable, structure is simpler, safeguard very convenient, can be widely used in the solar airconditioning of family expenses, as 20 square metres of households were freezed 8 hours every day, day irradiation level be to adopt 5-8 square metre solar adsorber area under 1000 watts the condition, can very move reliably, the present invention has broad application prospects.
