Description
Technical field
The present invention relates to absorbing refrigeration system technical fields, and in particular, to phase transformation continuous coo1ing adsorbs bed system.
Background technique
China still continues the propulsion phase in industrialization and urbanization, and the energy problem and environmental protection generated in the process is asked
Topic is widely noticed because being related to the quality of life of economic security of the country and the people.According to incompletely statistics, Chinese architecture energy consumption is about
Account for the 20-25% of social total energy consumption；Some cities of summer southern china, air-conditioner power consumption account for about the 35-55% of total power consumption, and
The ownership of Chinese air-conditioning is also increased with 30% or so speed, and the expectable ground of energy-output ratio is lasting to be increased.Meanwhile having every year
Million tons of freon leaks are into atmosphere --- it is known that freon not only greenhouse effects be carbon dioxide 2000 times of left sides
The right side, or destroy the main cause of earth's ozone layer.
In this context, solar energy is represented as outstanding new energy, by the favor of countries in the world.It is with photothermal technique
Main solar energy has been applied to every profession and trade, is constantly improving energy resource structure.Although China possesses the sun for accounting for about the world 70%
Energy heat utilization market, but the overwhelming majority is water heater product, and application field is narrow, and relevant market has been in development bottleneck
Phase.
Solar airconditioning this be generally considered with bright prospects but be difficult in a short time the marketization novel air
Unit is adjusted, again by the concern of industry.In hot summer, the power consumption of air-conditioning almost accounts for entire electric system power consumption
20-25%, this is one of the reason of summer electric system can't bear the heavy load.Therefore solar airconditioning has very big from the beginning
Temptation.
Current solar airconditioning technology is varied, mainly absorption refrigeration and absorption type refrigerating.Absorption type refrigerating
System can be driven by 65 DEG C of hot water, and all its is preferably in application of solar energy.Silica gel-water is the most common solar energy absorption
Air-conditioning work pair.Water is a kind of outstanding refrigerant, and the latent heat of vaporization is larger, so silica gel-water work is empty to absorption is only used in
In adjusting system.This technology in European market, has the silica gel-waters absorption air conditioner product such as ACS-08 and Sortech-AG to go out
It sells.But the major defect of the technology is that silica gel is smaller to the circulation absorption amount of water: under air conditioning condition, circulation absorption amount is
8-9%kgWater/kgAdsorbent, so such technology needs more adsorbent, so that the volume and cost of system are all larger；In addition,
Under heating operating condition, silica gel only has 1-2%kg water/kg adsorbent to the theoretical circulation adsorbance of water, so in practical applications
Silica gel-water is difficult to realize adsorption heat pump heating circulation.Furthermore the thermal coefficient of silica gel is lower, so the heat transfer of silica gel-water system
Coefficient is lower, to extend circulation time, thereby reduces the absorption refrigeration power of system.
Research in terms of absorption refrigeration has had many scientific research personnel to be studied.Through the document inspection to the prior art
Suo Faxian, number of patent application CN201520566476.1, patent name are a kind of " absorption of adsorption refrigeration device
The patent document of bed ", which is set in the thermal-arrest focus of heat collector, including stainless steel casing, fin, steel wire,
The steel wire is equipped with multiple medium passing channels, and medium passing channel is equipped with the fin, medium passing channel
Between fill adsorbent, be methanol gas circulation passage between adsorbent.The adsorption refrigeration device of the utility model
Adsorbent bed use fin case tube formula structure, heat absorption compares concentrations, heat exchange efficiency height.But the absorption of the patent document
Multiple medium passing channels are arranged in bed, this makes the metal heat of system and the resident heat of liquid larger, to reduce
System energy utilization efficiency.
Number of patent application is CN201510237643.2, and patent name is that " free convection heats and/or cools adsorbent bed
The patent document of absorption type refrigerating/heat pump assembly ", the patent document include absorber, heater, cooler, evaporator and cold
Condenser, which is characterized in that heating space, the cooling space of cooler of heater are mutually interconnected with absorber inner space respectively
It is logical；Heater and/or cooler cause inside absorber under the heat effect of heater and/or under the cooling effect of cooler
Gas free convection between the cooling space of the heating space and/or cooler of space and heater；Evaporator, condenser point
It is not interconnected with absorber inner space.The patent document can relatively rapid and be uniformly heated up/cool down adsorbent bed.But
It is that the adsorbent bed is heated and cooled down by the way of free convection, and heat transfer coefficient is extremely low, to greatly extend and be
The cycle period of system thereby reduces the coefficient of performance of system.
Number of patent application is CN201410001745.X, and patent name is " a kind of novel adsorption bed and the sun used
Can refrigeration system " patent document, the patent document include groove type heat collector, storage heater, adsorption refrigeration system, cooler,
Heat collector control valve, adsorbent bed control valve, circulating pump I, circulating pump II, three-way diverter valve I, three-way diverter valve II are constituted.
Adsorbent bed is applied in adsorption refrigeration system, including adsorbent bed outer housing, U-tube, fin, evaporator interface, condenser connect
Mouth, pressure gauge, temperature sensor, adsorbent bed support plate.Adsorbent bed heat source uses groove type solar collecting system, can be thermally conductive
Oil is heated to 180 DEG C~220 DEG C, and adsorbent on adsorbent bed can be made to carry out deep analysis, increase the refrigeration of unit refrigerant vapour
Amount.Adsorbent bed bed body uses fin tube type structure, effectively increases heat transference efficiency.But the absorption refrigeration of the patent document
More set heat transfers, such as the cooling line of heat-conducting oil heating pipeline and adsorbent bed are needed in system, which increase systems
Metal heat, to significantly reduce the coefficient of performance of system.
Number of patent application is CN200820012791.X, and patent name is " a kind of for Solid Adsorption Refrigeration System
The patent document of separated heat pipe adsorbent bed ", the patent document take cooler lower part to have a chamber, are equipped with top above the chamber
The coupled logical cylindrical shell of closed lower fills adsorbent and refrigerant between these cylindrical shells.Taking cooler
Chamber top is equipped with outer cover, and under shed is connected with cooler chamber is taken, and the through-hole for fluid disengaging is respectively equipped on the outer cover.
Cooler chamber lower portion is being taken to be equipped with lower connecting leg, the lower end of the lower connecting leg is connected with heat collector lower chambers.It is set on taking cooler chamber
Upper connecting leg, lower end of connecting leg is connected with heat collector upper chamber on this.Heat collector has heat pipe bundle arranged side by side, their upper end opening with
Heat collector upper chamber is connected, and lower ending opening is connected with heat collector lower chambers, in the case that above-mentioned heat pipe bundle peripheral hardware is contained
Body sets hot fluid inlet and outlet and valve thereon.The utility model adsorbent bed overall heat-transfer coefficient is high, the heat transfer area of unit volume
Greatly, adsorbent loading is big, high cooling efficiency.But the cooling capacity of the patent document needs to take cooler by heating pipe arranged side by side
Beam output, belongs to secondary heat exchange, to increase the thermal loss of system；On the other hand, the system of the patent document is more multiple
It is miscellaneous, it increases processing cost and reduces operational reliability.
