Description
Technical field
The present invention relates to Solar use and air-conditioning technical field, be specially a kind of Driven by Solar Energy list economic benefits and social benefits coupled mode lithium bromide refrigerator.
Background technology
Solar energy is widely distributed, that use is clean regenerative resource, is expected to play in future society energy resource structure more importantly act on.Wherein utilize solar energy carry out heat supply, heating and refrigeration be realize scale, important channel that low cost utilizes solar energy.Particularly; in recent years along with the scale of solar energy heating and heating system is applied; summer, solar heat excess phenomenon was very outstanding; scholars can realize utilizing summer solar energy to carry out the effective ways of air conditioner refrigerating positive searching; object is the annual utilization ratio that can improve solar thermal collector, can open up a brand-new technological approaches utilizing solar energy to solve air conditioner refrigerating demand on the other hand.The great advantage of solar airconditioning refrigeration is that it has matching in good season, and weather is warmmer, when more needing refrigeration, solar radiation condition is better, and the refrigerating capacity of solar refrigeration system is also larger.
Because current solar thermal collector is mainly used in hot-water heating system, usual heat-collecting temperature is below 90 DEG C, therefore the solar airconditioning technical elements that mating with ordinary solar heat collector of the priority application of solar airconditioning research in the past, particularly the single-effective absorption refrigerating machine group of production technology relative maturity, applies more.But the solar airconditioning be combined with low-temperature solar energy heat collection technology also exists some problems, on the one hand due to heat source temperature low (60-90 DEG C), the absorption of mating with it or absorption refrigeration unit generally freeze heating power COP between 0.4-0.7.On the other hand in order to ensure the continuity problem of solar airconditioning, general combustion gas or the oil burning boiler of adopting is as auxiliary thermal source.For the solar air-conditioner system that solar insuring rate is low, often lose due advantage (compared with conventional air conditioning system) because heating power COP is low.Mate with lithium bromide absorption type air conditioner can select the heating power COP that freezes be 1.2 economic benefits and social benefits product, but it needs the thermal source of 150 DEG C, and conventional direct-fired lithiumbromide absorption refrigerating machine is exactly the suction-type lithium bromide double-effect chiller adopting fuel oil or gas fired-boiler to drive.To adopt Driven by Solar Energy, then system needs to mate corresponding medium-temperature collectors.
In addition, for solar thermal collector, by the restriction of level of solar radiation, in the middle of one day, heat collector to supply heat temperature is lower when the morning and evening, reaches the highest before midday afterwards.To the solar air-conditioner system that medium-temperature collectors drives, generally close to noon, heat-collecting temperature could meet dual-effect refrigeration service requirement, the morning and afternoon portion of time, only can meet single-action refrigerating operaton condition.Therefore, extend solar airconditioning refrigeration system cooling time, best bet is the operational mode adopting single-action/economic benefits and social benefits to automatically switch, according to solar heat collector to supply heat variations in temperature in a day, automatically switch between single-action and economic benefits and social benefits pattern, to meet efficient, long-time refrigeration demand.
By finding the retrieval of prior art document, Chinese patent application publication No. is: CN101886854A, and denomination of invention is: Singledouble effect absorptive refrigerating machine.Propose the refrigeration machine that a kind of single economic benefits and social benefits switch, focus on setting forth the running ability how controlling middle weak solution pump according to the change of refrigeration load.Structure, it adds additional the generator and condenser that run for single-action on the basis of former direct combustion double-effect absorption refrigerating machine, and its generator run for single-action needs other heat source water to supply.And when single-action runs, high-low pressure generator and the condenser of former direct-fired economic benefits and social benefits unit all do not work, and system unit utilization rate is low.
