Problems solved by technology

For the open cold storage air-conditioning system, a cold storage pool is installed in the basement. Since there is no plate heat exchanger to isolate the high-rise terminal air-conditioning system from the cold storage pool, if the system pipeline valve is not closed tightly or fails, a large amount of water in the terminal air-conditioning system will be discharged. Falling water was poured back into the cold storage tank, resulting in an accident

Abstract

The invention provides an air conditioning pipeline system with a warning device capable of preventing falling water from flowing backwards. The air conditioning pipeline system comprises a water supplementing tank, a cold accumulation water pool, cold supply pumps, cold accumulation pumps, an air conditioning main machine and a terminal air conditioning system, and further comprises an early warning system, wherein the water supplementing tank is provided with a first sensor, the cold accumulation water pool is provided with a second sensor, and the first sensor and the second sensor are connected to the early warning system, and are used for transmitting hydrological data information of the water supplementing tank and the cold accumulation water pool to the early warning system; and thecold accumulation water pool is further provided with an automatic drainage valve, and the automatic drainage valve is connected with a controller of the early warning system. According to the air conditioning pipeline system with the warning device capable of preventing the falling water from flowing backwards, once the falling water flows backwards, the liquid level of the cold accumulation water pool exceeds a set value, and the automatic drainage valve can be automatically opened for drainage, so that the overflow accident of the cold accumulation water pool is prevented; and at the sametime, an alarm device is used for reminding a computer room manager to timely process the condition, so that the accident caused by backward flowing of the falling water is prevented.

Description

technical field [0001] The invention relates to the technical field of air-conditioning system design, in particular to an air-conditioning piping system provided with a warning device for preventing falling water and backflow. Background technique [0002] The air conditioning system will generate a certain amount of gas during operation, and the gas generally gathers at the highest position of the pipeline, so an automatic exhaust valve is generally installed at the highest position of the system pipeline. When the gas generated by the system gradually increases, the pressure continues to rise. When the pressure reaches the set value of the automatic exhaust valve, the automatic exhaust valve will discharge the gas in the system. After the gas in the system is discharged through the automatic exhaust valve, the water in the pipeline will be automatically replenished through the water supply tank installed on the roof of the tower. make the system run stably. For the open ...
