The use principle of the temperature control cabin with the temperature compensation function provided by the embodiment 1 is as follows: after water flows into the temperature control cabin, setting refrigeration or heating requirements according to use conditions; when low-temperature cold water is needed, the cold end is in contact with the temperature control cabin, the temperature of the water in the cabin body is reduced through temperature compensation, meanwhile, the high-efficiency heat dissipation of the hot end can promote the realization of temperature reduction, and the temperature reduction rate is accelerated; otherwise, when the low-temperature water in the cabin body needs to be heated, the contact end is set as the hot end, so that the water in the cabin body is heated.
The working conditions of the temperature control cabin with the temperature compensation function provided by this embodiment 1 are as follows: no matter the water in the water storage cabin body is in a static state or a flowing state, the temperature compensation can be continuously carried out, the temperature reaching the water outlet at the upper end of the flow guide pipe is finally a stable value, and the fluctuation of the temperature of the water flowing out of the temperature control cabin body can be effectively reduced.
Example 2
The gas heat exchange equipment that this embodiment 2 provided, including the indirect heating equipment body and the control by temperature change cabin in embodiment 1, the control by temperature change cabin is through second fixed bolster 412 fixed mounting on it in the indirect heating equipment body.
Through applying the temperature control cabin in embodiment 1 to present heat transfer equipment this internally (like gas heater body or heating stove body), effectual realized carrying out thermal compensation or cold compensation to the hot water or cold water that flow into this gas heat transfer equipment for the temperature of water that comes out from gas heat transfer equipment is invariable in a certain temperature range, has solved the problem of neglecting cold and neglecting hot, thereby satisfies user's bathing scene demand, improves user's use travelling comfort.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
