Protecting structure of drain pipe of central air conditioner

Abstract

The invention discloses a protecting structure of a drain pipe of a central air conditioner in the technical field of accessories of central air conditioners. The protecting structure comprises a first pipefitting connecting part, a second pipefitting connecting part and a three-way pipe and the like. Staff only needs to press a pressing plate with fingers to fix an insertion part in an insertionseat, so that an upper protecting shell and a lower protecting shell can be fixedly connected to the outer side wall of the drain pipe of the central air conditioner to play cold insulating and damp preventing roles to the drain pipe of the central air conditioner and prevent a condition that water in the drain pipe of the central air conditioner is easily condensed on the surface in a refrigerating process effectively, so that the condition that a ceiling is flooded is prevented. By opening an electromagnetic pulse valve, gas enters the three-way pipe at a relatively high pressure to blow blocking foreign matters adhered in the drain pipe of the central air conditioner. When the central air conditioner works again, the foreign matters are rushed out by water along with the drain pipe. Theprotecting structure is simple to operate and manpower- and time-saving.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning accessories, and the specific field is a central air-conditioning drainage pipe protection structure. Background technique [0002] The central air conditioner is composed of one or more cold and heat source systems and multiple air conditioning systems. The central air conditioner is mainly composed of a refrigerator, a cooling water circulation system, a fan coil unit, and a cooling tower. After the agent is compressed into a liquid state, it is sent to the evaporator for heat exchange with chilled water, and the chilled water is refrigerated. The chilled pump sends the chilled water to the cooling coil of each fan outlet, and is blown by the fan to achieve the purpose of cooling. After evaporation The refrigerant releases heat in the condenser and is in a gaseous state. The cooling pump sends the cooling water to the cooling tower, which is sprayed and cooled by the water tower...

Problems solved by technology

[0002] The central air conditioner is composed of one or more cold and heat source systems and multiple air conditioning systems. The central air conditioner is mainly composed of a refrigerator, a cooling water circulation system, a fan coil unit, and a cooling tower. After the agent is compressed into a liquid state, it is sent to the evaporator for heat exchange with chilled water, and the chilled water is refrigerated. The chilled pump sends the chilled water to the cooling coil of each fan outlet, and is blown by the fan to achieve the purpose of cooling. After evaporation The refrigerant releases heat in the condenser and is in a gaseous state. The cooling pump sends the cooling water to the cooling tower, which is sprayed and cooled by the water tower fan. At the same time, it exchanges heat with the atmosphere to dissipate the heat into the atmosphere. The water in the drain pipe of the central air conditioner is cold water during the cooling process, and its surface is prone to condensation, which will flood the ceiling in severe cases. And when the central air conditioner is used for a long time, the drain pipe is prone to clogging. To dredge the pipes, the operation is cumbersome, so a central air-conditioning drainage pipe protection structure is proposed
