It should be noted that the first refrigeration device 11 may be an adsorption refrigeration device, and specifically, refer to fig. 2, where fig. 2 is a schematic structural diagram of a system for supplying power by using an adsorption refrigeration device according to an embodiment of the present application.
As shown in fig. 2, a system for supplying energy using an adsorption type refrigeration apparatus may include: an adsorption bed assembly, a first condenser 114 and a first evaporator 115;
a fourth heat exchange medium is adsorbed in the adsorption bed assembly, and the second heat exchange medium is used for desorbing the fourth heat exchange medium and driving the fourth heat exchange medium to enter the first condenser 114;
the first condenser 114 is configured to condense the fourth heat exchange medium, and deliver the condensed fourth heat exchange medium to the first evaporator 115;

Specifically, the adsorption bed assembly may include a first adsorption bed 1131 and a second adsorption bed 1132, and the system further includes a plurality of three-way valves and two-way valves, and the specific number and arrangement positions may be as shown in fig. 2.
In this embodiment, the first inlet is the inlet of the two-way valve V10, the second heat exchange medium flows into the first adsorption bed through the two-way valve V10 and the three-way valve V1, heats the first adsorption bed, causes the temperature of the first adsorption bed to rise, and causes desorption, the refrigerant gas is released from the adsorption bed, enters the first condenser through the V5, is condensed into refrigerant liquid, and then enters the first evaporator. In the figure, a first water pump 116 pumps cooling water from a radiator 117 into a first condenser to condense refrigerant gas, then the cooling water flows out of the first condenser, enters a second adsorption bed through a two-way valve V6 to enable the temperature of the second adsorption bed to continuously drop to be adsorbed, then a V9 is opened, and refrigerant liquid in a first evaporator is continuously evaporated due to the action of pressure difference to generate cold energy which is carried away by a first heat exchange medium.
In addition, the adsorption refrigeration device also includes a quality returning process during the operation process, and in the process, since a part of the refrigerant in the first adsorption bed remains in the first adsorption bed in the process of entering the second adsorption bed, the refrigerant remaining in the first adsorption bed needs to be quality returned to the second adsorption bed for the next refrigeration operation. Specifically, the two-way valve V7 is opened, the two-way valves V5, V6, V8 and V9 are all closed, the second heat exchange medium enters the first adsorption bed through the two-way valve V10 and the three-way valve V1, so that the temperature of the first adsorption bed is continuously increased, the first adsorption bed is further desorbed, meanwhile, the cooling water enters the second adsorption bed through the three-way valve V2, so that the second adsorption bed is cooled and adsorbed, and thus, the refrigerant gas desorbed by the first adsorption bed enters the second adsorption bed through the two-way valve V7 and is adsorbed by the second adsorption bed.
After the quality returning process, the first adsorption bed is at a higher temperature, the second adsorption bed is at a lower temperature, and the first refrigeration device has two adsorption beds to perform desorption or adsorption alternately by the first adsorption bed and the second adsorption bed, so that in order to improve the efficiency of subsequent refrigeration, in the embodiment, after the quality returning process, a preheating and precooling process is added to pre-cool the adsorption bed with the higher temperature (here, the first adsorption bed) and preheat the adsorption bed with the lower temperature (here, the second adsorption bed). Specifically, the second heat exchange medium enters the second adsorption bed through V10 and V2 to raise the temperature of the second adsorption bed to a temperature near desorption, and the cooling water enters the first adsorption bed through V1 to lower the temperature of the first adsorption bed to a temperature near adsorption.
After the processes, the next round of refrigeration can be started, the round of refrigeration can desorb the second adsorption bed to adsorb the first adsorption bed, specifically, the second heat exchange medium enters the second adsorption bed through V10 and V2, the temperature of the second adsorption bed is continuously increased to desorb the second adsorption bed, cooling water enters the first adsorption bed through V1 to continuously reduce the temperature of the first adsorption bed, the desorbed refrigerant gas enters the first condenser through V6 to be condensed by the cooling water, then the condensed refrigerant enters the first evaporator, after V8 is opened, the condensed refrigerant is evaporated into gas under the pressure difference between the first adsorption bed and the first evaporator due to the fact that the first adsorption bed is in an adsorption state, the temperature of the first heat exchange medium is reduced, the refrigerant evaporated into gas enters the first adsorption bed through V8, the first adsorbent bed adsorbs the refrigerant.
Then enters a quality returning process, which is the same as the principle, except that the quality returning process is that the second heat exchange medium enters the second adsorption bed through V10 and V2, and the cooling water enters the first adsorption bed through V1.
The precooling and preheating process is also opposite to the previous process, cooling water enters the second adsorption bed through V2 to lower the temperature of the second adsorption bed to reach the temperature close to adsorption, and the second heat exchange medium enters the first adsorption bed through V10 and V1 to raise the temperature of the first adsorption bed to reach the temperature close to desorption.
It should be noted that the refrigeration unit in this embodiment may be a single-stage refrigeration unit, for example, an adsorption refrigeration unit or an absorption refrigeration unit, and of course, the refrigeration unit may also be a multi-stage refrigeration unit, that is, the first heat exchange medium is cooled for multiple times, for example, the first heat exchange medium may be a combination of an adsorption refrigeration device and an absorption refrigeration device, or a combination of more refrigeration devices, which is not described herein again.
