Description

Solar cold pipe and stride critical CO 2The associating energy supplying system
Technical field
The utility model relates to the joint dysfunction system that a kind ofly realizes freezing, heats with heat water supply functions.
Background technology
Because environmental problems such as global air temperature warming, unusual weather conditions are serious day by day, conventional primary energy (as oil, coal etc.) is petered out, environmental protection, energy-conservation and seek new forms of energy and become the great of present whole international community and urgent subject.
A large amount of at present freon family formula heat pump type air conditioning systems that use, summer, the thermal discharge of outdoor condenser was big, form localized heat and pollute, and the high more refrigerating efficiency of outside air temperature is low more, and energy consumption is high more; Northerly transition season or southern winter, when outside air temperature was lower, heat pump heat supply efficient was very low, needed to increase auxiliary electric heater unit and satisfied the demands, and energy consumption also increases greatly; In addition along with the raising of people's living standard, the demand of family life hot water is also increasing, its required energy consumption accounts for about 30% of family's total energy consumption, general employing electrical heating or combustion gas heating make hot water, air-conditioning system and hot water supply system are set up separately, utilization rate of equipment and installations is low, the cost height.
Solar cold pipe just can be finished solar energy adsorption/desorption kind of refrigeration cycle in a glass tube, it utilizes the solid adsorption refrigeration principle, adopt zeolite molecular sieve-water as absorption working pair to other working medium such as (also can adopt to) active carbon-methyl alcohol, adsorbent bed is filled compound adsorbent.Single solar cold pipe is exactly an energy conversion unit that integrates refrigeration, heat supply water.Adsorbent bed is by the compound adsorbent global formation, have heat and mass and adsorption/desorption performance preferably, its outer wall is double layer vacuum tube (glass outer tube and a glass inner tube), and the outside also has the glass bushing of a band selective coating, can also reduce heat waste greatly by efficient absorption solar energy.Be embedded with heat delivery line (SMIS heat pipe) at the adsorbent bed middle part, its interior heat transferring medium (cold water) that flows of absorption phase is lowered the temperature adsorbent bed rapidly, realizes the adsorbent bed efficient heat-collecting and the back efficiently radiates heat of keeping out of the sun in the sun.Condenser is positioned at the adsorbent bed bottom, be an individual layer package of connecting with condensation water tank (boiler), make refrigerant vapour fully obtain condensation by carrying out heat exchange with the condensation water tank cooling water, and make full use of the heat of condensation of cold-producing medium, provide the domestic hot-water with this heat.Evaporimeter is positioned at condenser, and cold-producing medium is housed in it, and in adsorbent when absorption cooling, the heat that the evaporation of evaporimeter by cold-producing medium absorbs chilled water in the evaporimeter water tank reaches the purpose of refrigeration, and this moment, cold was from the evaporimeter output of solar cold pipe.The structural representation of solar cold pipe is seen accompanying drawing 1, accompanying drawing 2.
The process of refrigerastion of solar cold pipe is: in the time of by day, adsorbent temperature raise after the solar cold pipe adsorbent bed was accepted solar radiation, bed inner refrigerant gas pressure rises, after reaching the cold-producing medium desorption temperature, the adsorbent bed temperature begins desorption, when the refrigerant vapour that comes out when desorption runs into condenser, because condenser temperature is lower than the saturation temperature of this moment under the pressure of cold-producing medium, so refrigerant vapour begins to carry out condensation on condenser, become the cold-producing medium of liquid, for the enforcing condensation effect, feed the cooling effect that cooling water is strengthened cold-producing medium at condenser, the condensation of refrigerant heat is outwards exported by hot water.Refrigerant liquid flows to evaporimeter by the self gravitation effect and stores.Constantly at dusk, solar radiation weakens, the adsorbent bed temperature of solar cold pipe begins to reduce, for its temperature can be reduced effectively fast, in the SMIS heat pipe, inject cold water, when the adsorbent bed temperature is reduced to the adsorbents adsorb temperature, refrigerant vapour around adsorbent in the adsorbent bed begins to adsorb, continuation along with adsorption process, the pressure of solar cold tube refrigerant steam reduces, when refrigerant vapour pressure is reduced to the saturated vapour pressure of liquid refrigerant in the evaporimeter, cold-producing medium in the evaporimeter begins vaporization, in the process of vaporization, need to absorb the latent heat of vaporization and keep vaporization, so produced refrigeration, the cold that evaporimeter is produced can be exported with chilled water, being transported to needs with cold place (as fan coil etc.), and the absorption refrigeration process is until the m seq adsorbent bed no longer till the absorption refrigeration agent steam.
CO 2As a kind of natural material, be comparatively desirable cold-producing medium, that its advantage is is nontoxic, do not fire, the ODP value is zero, greenhouse effects are less, cheap, need not reclaim, environment is free from side effects etc.Since 1866, to the thirties in 20th century, CO 2Subcritical cycle once was widely used, but because its efficient is lower, system works pressure height, reasons such as plant machinery requirement of strength height are replaced by afterwards freon system.
What is called is striden critical CO 2Circulation is meant CO 2Under the subcritical pressure condition, in evaporimeter, absorb heat, and under the supercritical pressure condition in gas cooler heat release (CO 2In this process, be always gaseous state and do not have condensation) circulation.Stride critical CO 2The exothermic process temperature of circulation is higher, and has a sizable temperature glide (about 80～100 ℃), is used for heat pump cycle and has special advantages.Studies show that under the same operating mode, (1) is heated to 60 ℃, CO with water from 10 ℃ 2Teat pump boiler is than electric heater and gas heater energy-conservation 75%; (2) CO 2Teat pump boiler can be produced the hot water that temperature reaches 90 ℃, and the hot water temperature of conventional heat pump system generally is lower than 55 ℃; (3) adopt CO 2Heat pump is commercial and residential housing hot-water supply, can make it always reduce 20% with energy; (4) CO 2Heat pump can be kept higher heating load under low temperature environment, save the auxiliary spent energy of firing equipment greatly.
