Intensive water seal system for air conditioner drainage pipe and drainage method

Abstract

The invention relates to a device for draining condensate, and discloses an intensive water seal system for air conditioner drainage pipes and a drainage method. The intensive water seal system is used for water seal of a plurality of drainage pipes with different pressures, the intensive water seal system comprises a buffer container arranged at the lower ends of the drainage pipes, a water seal overflow device used for draining water and an automatic water supplementing device used for keeping the water seal overflow device effective are arranged in the buffer container, and the lower ends of the drainage pipes are inserted below the liquid level of the buffer container. According to the intensive water seal system, the automatic water supplementing device is arranged, it is guaranteed that water used for the water seal overflow device cannot be dried up, and therefore the water seal takes effect all the time; through the arrangement of the large-capacity buffer container, water used for the water seal overflow device is not prone to drying up, the drainage pipes with different pressures not directly communicate any more, backmixing is prevented from being formed to affect normal work of an air conditioner, and the water seal effect cannot be affected even if water in the buffer container flows.

Description

technical field [0001] The invention relates to a device for draining condensate, in particular to an intensive water sealing system and a draining method for an air conditioner drain pipe. Background technique [0002] When the air-conditioning unit is working, condensed water will be generated on its surface cooler. At the same time, rain / snow water will enter the fresh air inlet of the air-conditioning unit during precipitation. Discharge through drain into sewer. The amount of condensed water or rain / snow water pouring into the fresh air inlet is not large, so when draining, the water does not fill the entire drain pipe, but flows against one side of the inner wall of the drain pipe. [0003] In order to prevent the dirty gas in the sewer from entering the room along the drain pipe, a trap needs to be installed at the end of the drain pipe. When draining, the water accumulated in the trap will form a water seal, preventing the dirty gas in the sewer from rising up. [...

AI Technical Summary

Problems solved by technology

This will bring about two problems. One is that after connecting the positive pressure pipe and the negative pressure pipe together, different functional sections will be connected, which will form back mixing to a certain extent and affect the normal operation of the air conditioner; After the positive pressure pipe and the negative pressure pipe are connected together, the two sides of the water trap are respectively under positive pressure and negative pressure. Under the synergy, the water in the water trap will be discharged, and the water sealing effect will be lost.
