The three-way proportional integral valve 7 is smashed on the side of the emergency cold storage device 3, and the three-way proportional integral valve 7 is adjusted according to the parameters set by the user, and the low temperature liquid and the high temperature liquid pass through the three-way proportional integral valve 7 and then enter the liquid mixer 8, The liquid mixture 8 is mixed into a uniform liquid that meets the setting requirements, and enters the air conditioning end module 2 through the liquid pump 9, and the heated liquid and the effluent liquid flowing out are returned to the emergency cold storage device 3 through the 501, so that the liquid storage device 3 is always kept closed. Top up. The air heated by the server cabinet 1 passes through the perforated floor 6, and enters the air conditioner end module 2 to become a low temperature air that meets the requirements. The fan 4 enters the server cabinet through the perforated floor 6 and completes a cycle.
