The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is further specified:
As depicted in figs. 1 and 2; The utility model discloses a kind of is the adsorption refrigeration system of driving heat source with solar energy; Comprise refrigeration system and collecting system; Refrigeration system comprises adsorption refrigeration system 1, auxiliary thermal source 2 and accumulation of energy water tank 3 successively, and it is the loop that adsorption refrigeration system 1, auxiliary thermal source 2 and accumulation of energy water tank 3 are communicated with; Said collecting system comprises solar thermal collector 4 and described accumulation of energy water tank 3, and said refrigeration system and collecting system are communicated with through said accumulation of energy water tank 3.Comprise also in the refrigeration system that first mechanical pump, 5, the first mechanical pumps 5 are arranged between said accumulation of energy water tank 3 and the adsorption refrigeration system 1; Collecting system also comprises second mechanical pump 6, and said second mechanical pump 6 is arranged between said solar thermal collector 4 and the described accumulation of energy water tank 3.Adsorption refrigeration system 1 comprises adsorbent bed 10; Be arranged on the condenser 11 of adsorbent bed 10 belows and be arranged on adsorbent bed 10 and condenser 11 between evaporimeter 12; Evaporimeter 12 is connected with accumulation of energy water tank 3 through first mechanical pump 5; Adsorbent bed 10, condenser 11 and evaporimeter 12 place same vacuum chamber from top to bottom, have constituted the adsorption refrigeration system of many cooperations.Between adsorbent bed 10 and evaporimeter 12, be provided with the valve body that control realizes the conversion of refrigeration modes, between said evaporimeter 12 and condenser 11, also be provided with the valve body that control realizes the conversion of refrigeration modes.Be set side by side with 1 101,2 102,3 103 and 4 104 in the adsorbent bed 10.Wherein, the direction of the direction indication water flows of arrow.
When intensity of solar radiation very high, when user institute chilling requirement requires to surpass the parameter that sets, for the As soon as possible Promising Policy user's request; At this moment, whole refrigeration unit realizes that through the switching of set pump and valve the double bed absorption type refrigerating of two parallel connections circulates, and hot water switches to 4 and 2 through valve sets; Adsorbent in heating two heats up it, and when the steam pressure in it surpassed the pairing saturated vapor pressure of condenser temperature, condenser was started working; Meanwhile; Cooling water switches to 1 and 3 through valve sets, is used for lowering the temperature adsorbing, and the water vapor pressure in the bed decreases; When pressure is lower than the pairing saturated vapour pressure of evaporimeter, the cooling of evaporimeter start vaporizer.Two while heating desorptions cool off absorption simultaneously, and the mode of operations of such two parallel connection circulations can realize continuous, stable refrigeration, and the refrigerating capacity that is reached is the basic twice that two circulations are only arranged.
And cold that user required very high when intensity of solar radiation is in the operating mode scope that is designed the time; This moment, the refrigerating capacity of refrigeration system had when remaining; For the reasonable use energy, store these temporary transient no energy get off, open cold accumulation system this moment; Select two adsorbent beds wherein to be in the work, two other adsorbent bed is realized the function of cold-storage.Through the opening and closing of pipe valve, hot water switches to 4 and 2 through valve sets, and the adsorbent in heating two makes its intensification; Be in desorption state, 4 refrigerant vapours of separating sucking-off get into condenser through valve, at this moment; Cooling water switches to 3 through valve sets; When 3 inner refrigerant steam pressures were lower than the saturated vapor pressure of evaporimeter, evaporimeter was started working, and 4 and 3 have constituted basic continuity adsorption refrigeration system.And in getting into 1 by 2 refrigerant vapours that desorb through valve, this moment, 2 valves that are connected with evaporimeter were in closed condition, prevented that adsorbent and cold-producing medium are in contact with one another, realization absorption type cool storage function.When user's refrigeration requirement became big, with connecting the valve open of adsorbent bed 2 with evaporimeter, got into 2 bed from the refrigerant vapour that evaporimeter comes out this moment, and the cold that is held is released out, thereby meets consumers' demand.
When the not high and user of intensity of solar radiation still has refrigeration requirement, because the temperature of driving heat source is lower, can not effectively drive basic kind of refrigeration cycle, at this moment, system switches to the two-stage adsorption type kind of refrigeration cycle.When refrigeration system is in the two-stage operational mode; Be connected between adsorbent bed 4 and the condenser, carry out heating desorption, adsorbent bed 1 is as the condenser of adsorbent bed 2; Be connected with adsorbent bed 2; Thereby utilize the desorption of bed 2 and the suction-operated of itself, accomplish the heating desorption process of adsorbent bed 2, adsorbent bed 1 cooling absorption simultaneously is until reaching capacity; Adsorbent bed 3 is connected with evaporimeter; Carry out absorption refrigeration, adsorbent bed 4 is connected with condenser, and the refrigerant vapour at adsorbent bed 4 heating desorption places gets into condenser condenses; Through the condensed refrigerant liquid U type pipe of flowing through; Get into then in the evaporimeter, this moment, evaporimeter was connected with adsorbent bed 3, reached the refrigeration purpose thereby adsorbent bed 3 is cooled off absorption.Adsorbent bed 1 shown in the figure is as the condenser of adsorbent bed 2; On the one hand since its pairing condensing pressure than low many of the pairing condensing pressure of condenser; So under the situation identical with the pairing minimum adsorbance of normal circulation, bed heated 2 pairing heat source temperatures also reduce.Adsorbent bed 4 is owing to pairing pressure in adsorption process is bigger; So its maximal absorptive capacity will improve under same sink temperature condition effectively; Requiring under the same circulation adsorbance condition like this, bed 4 needed heat source temperatures also can effectively reduce.
When intensity of solar radiation was very weak, the shortage of heat that it provided was to drive the adsorption refrigeration system operation, in order to satisfy user's refrigeration requirement; At this moment, the auxiliary thermal source system opens, and comes the assisted solar hot water device to drive refrigeration unit by natural gas auxiliary thermal source system heat cycles water; Reach when water temperature after the actuation temperature of silica gel-water; Refrigerating plant brings into operation, and in order to save the energy, hot water temperature's control is lower; Whole kind of refrigeration cycle is controlled in the two-stage operating condition, thereby meets consumers' demand.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
