Optionally, as shown in fig. 1, the liquid cooling unit further includes a first electronic expansion valve 17 and a second electronic expansion valve 18, where the first electronic expansion valve 17 is connected between the evaporator 30 and the condenser 14, and the second electronic expansion valve 1 is connected between the third heat exchanger 12 and the condenser.
In some embodiments, the first electronic expansion valve 17 and the second electronic expansion valve 18 are identical in structure and model, and are convenient to purchase and install.
In at least one embodiment, by arranging the first electronic expansion valve 17 and the second electronic expansion valve 18 and connecting the first electronic expansion valve and the second electronic expansion valve between the evaporator 30 and the condenser 14 and between the third heat exchanger 12 and the condenser 14, the flow rates of the circulating liquid flowing through the evaporator 30 and the third heat exchanger 12 can be accurately adjusted respectively, and further the working conditions such as the temperature in the electric bin, the battery bin and the high-pressure box can be accurately adjusted in real time, so that the temperature and humidity adjusting effect is improved.
In addition, one or more embodiments of the present application provide an energy storage device including a temperature and humidity regulation system as described above.
In some embodiments, the energy storage device further comprises an electrical bin and a battery bin, wherein a plurality of clusters of batteries 01 are arranged in parallel in the battery bin, and a plurality of high-voltage boxes 02 are arranged in parallel in the battery bin.
In at least one embodiment, the energy storage device may be a device such as an energy storage cabinet or an energy storage container, and of course, the energy storage device may also be other devices equipped with the temperature and humidity adjustment system according to the present application, which is not limited herein. The energy storage device and the temperature and humidity regulation system have the same advantages as those of the prior art, and the assembly of the temperature and humidity regulation system to the corresponding energy storage device is a common technical means understood by those skilled in the art, and will not be described herein.
The foregoing has outlined the basic principles, features, and advantages of the present application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims. The scope of the application is defined by the appended claims and equivalents thereof.
