[0002] In order to prevent condensation at the radiation end during operation, existing radiation air conditioning systems usually need to use water mixing equipment to mix the water supply. The radiation air conditioning system is a multi-device integrated system, which usually requires professional designers to design the system, weld pipes and assemble components at the construction site. This kind of engineering practice will not only increase the construction volume, but also place higher requirements on construction personnel due to the complexity of the system, and will also increase the construction time.
