Adsorption refrigerator with thermostatic control

Abstract

An adsorption type refrigerator with thermostatic control includes a first vacuum chamber, a second vacuum chamber, a third vacuum chamber, and a passage structure. The first vacuum chamber accommodates a first adsorption bed, a first condenser, and a first evaporator, and the second vacuum chamber accommodates a second adsorption bed, a second condenser, and a second evaporator. The third vacuum chamber contains a third evaporator. The passage structure guides hot water into the first adsorption bed and guides cold water into the second adsorption bed simultaneously, or guides the cold water into the first adsorption bed and guides the hot water into the second adsorption bed simultaneously. According to the ambient temperature or the temperature of ice water produced by the adsorption refrigerator, the cold water is stopped being guided into the first or the second adsorption bed timely, thereby ceasing the refrigeration temporarily and achieving the thermostatic control.

 a first vacuum chamber accommodating a first adsorption bed, a first condenser and a first evaporator, wherein the first adsorption bed has a first intake and a first outlet;   a second vacuum chamber deposited abreast with the first vacuum chamber and accommodating a second adsorption bed, a second condenser and a second evaporator, wherein the second adsorption bed has a second intake and a second outlet;   a third vacuum chamber having a top connected with bottoms of the first vacuum chamber and the second vacuum chamber, and accommodating a third evaporator, wherein the third evaporator has an ice-water intake and an ice-water outlet; and   a passage structure including a plurality of pipings and a plurality of valves, wherein the pipings are intercommunicated through the plurality of valves, and the passage structure is configured to guide hot water into the first adsorption bed and guide cold water into the second adsorption bed simultaneously, or to guide the cold water into the first adsorption bed and guide the hot water into the second adsorption bed simultaneously,   wherein, when the ambient temperature or the temperature of the ice water at the ice-water outlet is lower than a predetermined temperature, the cold water is stopped being guided into the second adsorption bed or the first adsorption bed.   
     
     
         2 . The adsorption type refrigerator with thermostatic control of  claim 1 , further comprising a temperature sensor for detecting the temperature of the ice water. 
     
     
         3 . The adsorption type refrigerator with thermostatic control of  claim 1 , wherein the plurality of valves includes:
 a first valve allowing the hot water coming from a hot-water intake to reach the first intake or the second intake;   a second valve allowing the first outlet or the second outlet to communicate with a hot-water outlet;   a third valve connected to a cold-water intake and a cold-water outlet;   a fourth valve connected to the third valve and allowing the cold water passing through the third valve to reach the first intake or the second intake; and   a fifth valve allowing the first outlet or the second outlet to communicate with the cold-water outlet,   wherein, when the ambient temperature or the temperature of the ice water is lower than the predetermined temperature, the third valve makes the cold water coming from the cold-water intake get drained through the cold-water outlet directly.   
     
     
         4 . The adsorption type refrigerator with thermostatic control of  claim 1 , wherein the plurality of valves includes:
 a sixth valve connected to a hot-water intake;   a seventh valve connected to the sixth valve and to a hot-water outlet;   an eighth valve connected to the sixth valve to the first intake, and the second intake;   a ninth valve connected to the seventh valve, and connected to the first outlet and the second outlet, while being connected to the pipe between the sixth valve and the eighth valve through a bypass pipe;   a tenth valve connected to a cold-water intake and a cold-water outlet;   an eleventh valve connected to the tenth valve, to the first intake, and to the second intake; and   a twentieth valve connected to the cold-water outlet, to the first outlet, and to the second outlet,   wherein the eighth valve is configured to guide the hot water coming from the hot-water intake into the first adsorption bed or the second adsorption bed, and the eleventh valve is configured to guide the cold water coming from the cold-water intake into the first adsorption bed or the second adsorption bed, while the tenth valve is configured to make the cold water coming from the cold-water intake directly drained out through the cold-water outlet when the ambient temperature or the temperature of the ice water is lower than the predetermined temperature.   
     
     
         5 . The adsorption type refrigerator with thermostatic control of  claim 1 , wherein the first condenser and the second condenser share a common condensing tube, which is connected between the first vacuum chamber and the second vacuum chamber. 
     
     
         6 . The adsorption type refrigerator with thermostatic control of  claim 1 , wherein the first evaporator and the second evaporator each comprises:
 at least one evaporator tray for carrying a heat-transfer medium; and   a heat-transfer piping passing through each said evaporator tray, and having two ends connected to the third vacuum chamber respectively.   
     
     
         7 . The adsorption type refrigerator with thermostatic control of  claim 1 , wherein the third evaporator comprises:
 at least one evaporation heat-transfer tray for carrying a heat-transfer medium; and   a heat-exchanging piping having two ends acting as the ice-water intake and the ice-water outlet, respectively, and passing through each said evaporation heat-transfer tray.   
     
     
         8 . The adsorption type refrigerator with thermostatic control of  claim 1 , further comprising three adjustment pipes, wherein each of the adjustment pipes is correspondingly communicated with the first vacuum chamber, the second vacuum chamber and the third vacuum chamber, for independently refilling or vacuuming the corresponding first vacuum chamber, the second vacuum chamber, and the third vacuum chamber.
