Description
Technical Field
The utility model relates to an air conditioner washs technical field, especially relates to a pipe connection spare that is used for central air conditioning to energy-conserving external circulation system of wasing.
Background
With the development of society, more and more places adopt central air conditioning to carry out indoor temperature regulation in China. The water quality problem of the central air conditioner in the using process is more and more prominent. When the central air conditioner is operated, substances such as dust, waste gas and the like are concentrated on an evaporator of an indoor unit of the air conditioner, particularly an underground parking lot or a factory which is easy to generate dust and waste particles, and therefore a large amount of dust fibers and dirt are easy to accumulate in places such as the evaporator of the central air conditioner. When the central air-conditioning evaporator is in a spring and summer season changing environment or plum rainy season, mildew is easy to breed in a humid environment to cause harm to human bodies, in addition, when a pipeline in the central air-conditioning evaporator is in a blocked state, the heat and cold exchange efficiency reduces the power consumption of the central air conditioner to be increased, and meanwhile, the central air-conditioning compressor unit is easy to have a high-voltage protection or overcurrent protection phenomenon. These phenomena make it difficult for the operating personnel to cope with and affect the normal operation of the central air conditioner.
In the prior art, the central air-conditioning system is usually cleaned in an integral manner, namely, a pipeline, a cooling tower and a condenser of the central air-conditioning cooling system are repeatedly washed by a cleaning agent through a water pump. A special brush is extended into the shell of the condenser of the central air conditioner to loosen the dirt in the tube bundle, and the cleaning agent washes out the loosened dirt, so that the inside of the condenser tube bundle of the central air conditioner achieves the effects of removing rust, preventing rust, removing scale and preventing scale, and controlling the growth of microorganisms, thereby ensuring the normal operation of the central air conditioner; however, with the integral cleaning of the prior art, there are several disadvantages, first: the energy consumption is high, the dirt generated by the central air-conditioning system is mainly concentrated in the condenser tube bundle at the tail end of the system, and the cooling system of the central air-conditioning system has long pipelines and large diameters of the pipelines, needs to consume a lot of water resources and cleaning chemicals and water aqua and takes a lot of time. Secondly, the method comprises the following steps: the cleaning agent is corrosive, and is usually cleaned in an integral manner, so that the cleaning agent is easy to corrode parts such as cooling towers and pipelines of cooling systems, and the service life of the cleaning agent is influenced. When a central air-conditioning system is cleaned by a central air-conditioning cleaning service company, the central air-conditioning water system is basically provided with a water system exhaust and a water system drain outlet, after the main machine is installed or in the normal water-changing process, the heat exchanger of the main machine is used for removing air and draining water in the heat exchanger of the main machine, when the air exhaust/pollution discharge is not carried out, the pipe is sealed by the screw thread, and the internal screw thread connector can also be externally connected with a pipeline, therefore, the circulating system of the external cleaning condenser is designed, the pipeline connecting piece is connected with the exhaust/sewage discharge port, the stop valves of the water inlet pipeline system and the water outlet pipeline of the condenser are closed, cleaning agent is pumped into the condenser through the circulating pump to flush the copper pipe in the condenser, the cleaning agent does not pass through pipeline systems such as cooling towers and the like, and the method can quickly clean the condenser of the central air conditioner, reduce the waste of water resources and cleaning liquid medicine, save labor cost and the like.
However, because the existing central air-conditioning systems have more brands and companies for installing and serving the central air-conditioning systems are more, the pipe connectors matched with the internal thread connectors which are used as exhaust and sewage discharge ports do not have uniform size specifications, and generally comprise external threads DN20,4/3 inches, external threads DN25,1 inch, external threads DN32,1.25 inches, external threads DN40 and 1.5 inches, and the cleaning of the central air-conditioning system is usually carried out by a professional air-conditioning cleaning service company as a professional technology.
