Central air-conditioning condenser online cleaning system

Abstract

An online cleaning system for central air-conditioning condensers, including: a ball loader, a ball collector, and cooling pipes connected at both ends of the condenser. The ball loader divides it into upper and lower containers through a grille. The ball is provided with a water inlet, a ball return port, and a ball outlet; the pipe connecting the water inlet to the cooling water pipe is the water inlet pipe; the pipe connecting the ball outlet to the ball sprayer is the ball delivery pipe, and the nozzle of the ball sprayer is inserted into the condenser inlet The cooling water pipeline at the place; the ball return port is connected with the ball collector to form the ball return pipeline, which is characterized in that: a branch is set on the ball return pipeline and the cooling water return pipeline, and a check valve is set in the branch, and A screen is set between the branch and the recovery ball pipeline. It avoids the clogging of the rubber balls at the outlet of the ball return device and the extrusion of the rubber balls and garbage on the surface of the ball collection net, causing the water flow to be blocked and the pressure of the system water to rise. It saves energy and ensures the stability of the system. The ball rate reaches 100%, and the condenser pipes are cleaned in place.

Description

technical field [0001] The invention relates to a cleaning system for cleaning a condenser in a central air conditioner, especially for cleaning pipes of a heat exchanger used in the condenser. Background technique [0002] The present invention is particularly directed to the cleaning system described in Chinese invention patent 96107005.6. Such a cleaning system includes pellets that circulate with the water flow through the pipe from its upstream side to its downstream side, a separator system to separate the pellets from the small stream at the downstream side of the pipe, and a Recirculation system on the upstream side. In the Chinese invention patent 96107005.6, the final channel of the recirculation system is connected to the atmosphere; the separator system includes: a grid connected to the ball catcher housing on the downstream side of the pipeline, which is located inside the ball catcher housing to form a pellet In the collector chamber, the grille is installed ...

AI Technical Summary

Problems solved by technology

[0004] 1. The rubber ball is easy to block at the exit of the ball return

[0005] 2. Rubber balls and garbage are squeezed on the surface of the ball collection net, causing blockage of water flow, increasing the pressure of the system water, and wasting energy

At the same time, it affects the stability of the system
