As shown in fig. 2, in the present embodiment, the evaporator 20 further includes: and a main pipeline 25, wherein the main pipeline 25 connects the multiple sections of evaporators 20 in series in sequence and is communicated with the evaporators in sequence. In addition, inside each section of evaporator, the main pipeline 25 connects outlets and inlets of two adjacent sub-evaporators, and the plurality of sub-evaporators of each section of evaporator are sequentially connected in series on the main pipeline 25 along the length direction of the main pipeline 25 and are sequentially communicated by the main pipeline 25, for example, the first sub-evaporator 211, the second sub-evaporator 212 and the third sub-evaporator 213 are sequentially connected in series by the main pipeline 25 and are sequentially communicated.
In fig. 2, the arrows represent the flow direction of the refrigerant, and the front in the arrow direction is the downstream, and the rear in the arrow direction is the upstream. As shown in fig. 2, according to one embodiment of the present invention, each stage of the evaporator 20 includes: at least one bypass line 26 and at least one control valve block 27. The number of the bypass lines 26 of each section of evaporator may be equal to the number of the sub-evaporators of the section of evaporator, or may be one less than the number of the sub-evaporators of the section of evaporator, and the number of the control valve sets 27 is equal to the number of the bypass lines 26.
In one embodiment of the present invention, as shown in fig. 2, the four-stage evaporator of the evaporator 20 has two bypass lines and two control valve sets, and the number of the bypass lines 26 is one less than that of the sub-evaporators, for example, the bypass line 26 of the first evaporator 21 includes a first bypass line 261 and a second bypass line 262, wherein the first bypass line 261 corresponds to the second sub-evaporator 212, and the second bypass line 262 corresponds to the third sub-evaporator 213.
The inlet of the bypass pipeline 26 is connected with the main pipeline 25 of the inlet of the sub-evaporator, and the outlet of the bypass pipeline 26 is connected with the main pipeline of the outlet of the last sub-evaporator of the section of evaporator. The control valve set 27 is respectively located on the main pipeline 25 and the bypass pipeline 26, and is used for controlling the flow direction of the refrigerant.
In this embodiment, the air cooling assembly 100 further includes: a damper (not shown) is provided at the air intake end of the air duct 10. The air flow entering the air duct 10 is controlled by the air door, so that the low-temperature air flow entering the refrigerating compartment is controlled, and the temperature of the refrigerating compartment can be adjusted. For example, if the temperature of the refrigerated compartment is low, by closing the damper, no air flow enters the duct 10, and no low temperature air flow enters the refrigerated compartment, thereby preventing the temperature of the refrigerated compartment from continuing to drop. Conversely, if the temperature of the refrigerating chamber is higher, the low-temperature airflow can be conveyed into the refrigerating chamber by opening the air door, and the temperature of the refrigerating chamber is further reduced. The air door has simple structure and convenient operation, and can provide convenience for a user to control the temperature of the refrigerating chamber.
The communication and closing of the sub-evaporators can be controlled through the corresponding bypass pipelines 26 of the sub-evaporators and the control valve group 27, so that the communication quantity of the sub-evaporators is controlled, and the accurate temperature control of the refrigerating chamber is finally realized by combining the opening and closing of the air door.
As shown in fig. 2, in the present embodiment, an inlet of the first bypass line 261 is connected to the main line 25 of the inlet of the second sub-evaporator 212, and an outlet of the first bypass line 261 is connected to the main line 25 of the outlet of the third sub-evaporator 213, which is the last sub-evaporator of the first evaporator 21; accordingly, an inlet of the second bypass line 262 is connected to the main line 25 of the inlet of the third sub-evaporator 213, and an outlet of the second bypass line 262 is connected to the main line 25 of the last sub-evaporator of the first evaporator 21, i.e., the outlet of the third sub-evaporator 213.
As shown in fig. 2, according to an embodiment of the present invention, the control valve set 27 includes a main control valve 271 and a bypass control valve 272, the main control valve 271 is located on the main pipeline 25 and is located between the connection points of the sub-evaporator inlet and the bypass pipeline 26 inlet with the main pipeline 25, that is, the bypass pipeline inlet is connected with the main pipeline 26 and has a connection point, the main control valve 271 is located between the connection point and the sub-evaporator inlet, and the bypass control valve 272 is located on the bypass pipeline 26.
The bypass line 26 and the control valve group 27 control the cut-off and communication of the sub-evaporators, and when the main path control valve 271 is opened and the bypass control valve 272 is closed, the sub-evaporators communicate with the main line 25 and the refrigerant enters the sub-evaporators. When the main control valve 271 is closed and the bypass control valve 272 is opened, the sub-evaporator is disconnected from the main line 25, and the refrigerant enters the bypass line 26 without entering the sub-evaporator.
The communication and closing of the sub-evaporators can be controlled through the corresponding bypass pipelines 26 of the sub-evaporators and the control valve group 27, so that the communication quantity of the sub-evaporators is controlled, and finally, the accurate temperature control of the refrigerating chamber is realized.
In other words, the control valve set 27 can control the refrigerant in the main pipeline 25 to enter the sub-evaporator, and can also control the refrigerant in the main pipeline 25 to enter the bypass pipeline 26 and then return to the main pipeline 25. That is, the control valve set 27 can control the refrigerant to pass through the sub-evaporator and exchange heat with the air flow outside the sub-evaporator, or control the refrigerant not to pass through the sub-evaporator.
Therefore, the bypass pipeline 26 and the control valve group 27 are matched to control the flow direction of the refrigerant, so that the temperature of the sub-evaporator is controlled, the heat exchange condition of the low-temperature air flow passing through the air duct 10 and the sub-evaporator is adjusted by controlling the working condition of the sub-evaporator, the temperature of the low-temperature air flow entering the refrigerating chamber is controlled, and the temperature of the refrigerating chamber is adjusted. The adjustability of air cooling assembly 100 is improved, and convenience is provided for a user to control the refrigeration equipment.
Further, in this embodiment, the control valve set 27 may be a three-way valve, an inlet of the three-way valve is connected to the main pipeline 25, an outlet of the three-way valve is connected to the main pipeline 25 of the inlets of the sub-evaporators, another outlet of the three-way valve is connected to the inlet of the bypass pipeline, and the three-way valve is located between two adjacent sub-evaporators and connected to the bypass pipeline. Specifically, the three-way valve has an inlet, a first outlet and a second outlet, the inlet and the first outlet are communicated with the main pipeline 25 to ensure that the main pipeline 25 is normally communicated, and the inlet and the second outlet are communicated with the bypass pipeline 26.
As shown in fig. 2, according to another embodiment of the present invention, the control valve group 27 includes: a main control valve 271 and a bypass control valve 272.
The main control valve 271 is disposed on the main pipeline 25, is located between the connection point of the inlet of the second sub-evaporator 212 and the inlet of the bypass pipeline 26 with the main pipeline 25, and is used for controlling the conduction or the closure of the main pipeline 25 at the inlet of the second sub-evaporator 212, and the bypass control valve 272 is disposed on the bypass pipeline 26 and is used for controlling the conduction or the closure of the bypass pipeline 26.
When the air cooling assembly 100 works, the main path control valve 271 is opened, the bypass control valve 272 is closed, and the refrigerant passes through the second sub-evaporator 212 and exchanges heat with air; the main path control valve 271 is closed and the bypass control valve 272 is opened, and the refrigerant passes through the bypass line 26 and returns to the main line 25 without passing through the second sub-evaporator 212 and the third sub-evaporator 213 to exchange heat with the air, and at this time, only the first sub-evaporator 211 is in an open state. Accordingly, when the main path control valve 271 corresponding to the third sub-evaporator 213 is opened and the bypass control valve is closed, the refrigerant passes through the third sub-evaporator 213 and exchanges heat with the air; when the main path control valve 271 is closed and the bypass control valve 272 is opened, the refrigerant passes through the bypass line 26 and directly returns to the main line 25, does not pass through the third sub-evaporator 213, and does not exchange heat with the air, and only the first sub-evaporator 211 and the second sub-evaporator 212 are in an open state at this time. Therefore, the temperature in the air duct 10 is controlled by controlling the opening and closing of each sub-evaporator, which is simple and convenient.
As shown in fig. 2, in the present embodiment, the bypass line 26 includes: a first bypass line 261 and a second bypass line 262. An inlet of the first bypass line 261 is connected to the main line 25 of the inlet of the second sub-evaporator 212, and an outlet of the first bypass line 261 is connected to the main line 25 of the outlet of the last sub-evaporator, that is, the third sub-evaporator 213, of the first evaporator 21; accordingly, an inlet of the second bypass line 262 is connected to the main line 25 of the inlet of the third sub-evaporator 213, and an outlet of the second bypass line 262 is connected to the main line 25 of the last sub-evaporator of the first evaporator 21, i.e., the outlet of the third sub-evaporator 213. In the present embodiment, the connection pipeline of the outlet of the first bypass pipeline 261 and the outlet main pipeline 25 of the third sub-evaporator 213 shares a same section with the connection pipeline of the outlet main pipeline 25 of the second bypass pipeline 262 and the third sub-evaporator 213.
Further, the air-cooling assembly 100 further includes: and the temperature sensor (not shown) is arranged at the air outlet end of the air duct 10 and is in communication connection with the air door. The temperature sensor is arranged at the air outlet end of the air duct 10 and can detect the temperature of the refrigerating chamber, when the temperature of the refrigerating chamber is low, the temperature sensor detects a low-temperature signal, and the air door is closed to prevent low-temperature airflow from continuously entering the refrigerating chamber. When the temperature of the refrigerating chamber is increased, the temperature sensor detects a high-temperature signal, the air door is opened, and low-temperature airflow enters the refrigerating chamber.
Therefore, the temperature condition of the refrigerating chamber can be automatically adjusted by utilizing the matching of the temperature sensor and the air door and the control of the opening quantity of the sub-evaporators in the air duct 10, so that the automation degree of the air cooling assembly 100 and the refrigerating equipment is improved, and convenience is provided for a user to use the refrigerating equipment.
