The following describes the specific structure of the modular heating and cooling wall system according to the embodiment of the present invention with reference to FIG. 1.

As shown in FIG. 1, the modular heating and cooling wall system of the embodiment of the present invention includes a pump module 1 and a heat exchange module 2, and there are one or more heat exchange modules 2.

The first heat exchange module 13 has a first water inlet pipe 131 and a first water outlet pipe 132. The module 11 is buried in the ground; the heat exchange module 2 includes a second energy storage module 21 and a second heat exchange module 22. The second heat exchange module 22 has a second water inlet pipe 221 and a second water outlet pipe 222. The energy storage module 21 is buried underground; one end of the water pump module 12 is connected to the user return pipe 6, and the other end is connected to the first water inlet pipe 131 of the first heat exchange module 13 and the second heat exchange module 22 The two water inlet pipes 221 are connected; the first water outlet pipe 132 of the first heat exchange module 13 and the second water outlet pipe 222 of the second heat exchange module 22 are connected, and the water outlet of the first heat exchange module 13 is connected to the second heat exchange module After the effluent of the group 22 merges, it exchanges heat with the second energy storage module 21 and the first energy storage module 11 in sequence, and then flows to the user water supply pipe 7.

First of all, it should be noted that in the actual heating or cooling process, the water flow of the user return pipe 6 is divided into multiple streams under the drive of the water pump module 12, and one stream enters the first heat exchange module 13 from the first water inlet pipe 131 After heat exchange, it flows out from the first water outlet pipe 132, and the remaining water flows from the second water inlet pipe 221 to the second heat exchange module 22 and flows out from the second water outlet pipe 222 after heat exchange.

It should be noted that in areas where centralized heating and cooling is required, it is often necessary to implement a building with a combined heating and cooling system due to the order of customers’ stay or the overall schedule of the developer’s project. The existing combined heating and cooling system can only pre-lay all the combined heating and cooling systems, and the laying period is long, and it is easy to cause the simultaneous cooling and heating of the unmanned building and the manned building during use, which is a huge waste of resources. In the modular heating and cooling wall system of the present invention, the modular heating and cooling wall system includes a pump module 1 and one or more heat exchange modules 2.

The water flow in the tube 1122 exchanges heat to realize heating or cooling of the water flow. Since one end of the first heat exchange tube 1122 is connected to the second energy storage module 21, it means that the flow from the first water outlet pipe 132 and the second water outlet pipe 222 is heated or heated by the second energy storage module 21. After cooling, it is heated or cooled by the first energy storage module 11, thereby increasing the heating or cooling capacity of the modular heating and cooling wall system, and better meeting the needs of users.

Since one end of the second heat exchange tube 2122 is connected to the first heat exchange tube 1122 or the second heat exchange tube 2122 of the other heat exchange module 2, it means that the flow from the first outlet pipe 132 and the second outlet pipe 222 After heating or cooling by one or the second energy storage module 21, it can also be heated or cooled by the first energy storage module 11, thereby increasing the heating or cooling of the modular heating and cooling wall system The quantity, to better meet the needs of users.
