Description

Air supply system

Technical Field

The utility model belongs to the technical field of the ventilation air conditioning system, the utility model relates to an air supply system. In particular to a low-cost air supply system.

Background

In ventilation air conditioning system, the condition that terminal fan coil static pressure is not enough often can take place, and traditional transformation mode is: and (4) dismantling an air pipe joint and a water pipe joint of the original fan coil, and replacing a new fan coil and connecting a water pipe and an air pipe. The traditional transformation mode not only greatly increases the overall cost of the system, but also has higher construction difficulty.

The prior art has the following defects:

(1) the whole construction cost of the project is increased.

(2) The construction difficulty is higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming not enough among the above-mentioned background art, in order to reduce the whole cost and the construction degree of difficulty of the transformation project that is not enough to terminal fan coil static pressure among the ventilation air conditioning system, provide an air supply system, this air supply system simple structure saves the cost, has reduced the construction degree of difficulty.

The utility model provides a technical scheme that its technical problem adopted is: an air supply system comprises an air pipe A, a fan and an air pipe B which are sequentially connected; the other end of the air pipe A is connected with a fan coil, the front end of the fan coil is provided with an air return box, and the lower end of the air return box is provided with an air return port; the lower end of the air pipe B is provided with an air pipe C, and the bottom of the air pipe C is provided with an air supply outlet; the fan coil is also connected with two pipelines; one pipeline is sequentially connected with a metal flexible connector, a ball valve and a water return pipe; the other pipeline is sequentially connected with a metal flexible connector, an electromagnetic valve, a filter, a ball valve and a water supply pipe; the fan coil is also connected with a temperature controller.

Furthermore, the bottom of the fan coil is connected with a condensate pipe through a pipeline.

Furthermore, the electromagnetic valve is connected with a temperature controller.

Furthermore, a silencer is arranged between the fan and the air pipe B.

Furthermore, an air return inlet flexible connection is arranged between the air return box and the air return inlet.

Compared with the prior art, the utility model beneficial effect who has is:

(1) the cost of the project for improving the ventilation air-conditioning system is avoided from being greatly increased.

(2) The construction difficulty of the ventilation air-conditioning system transformation project is reduced.

Simultaneously the utility model provides a pair of air supply system has still solved because the interior decoration problem, and the tuber pipe overlength that fan coil joined in marriage leads to fan coil's static pressure to be not enough to overcome the resistance of tuber pipe and when sending end user, increases the fan between the tuber pipe to increase air supply pressure, can be enough to overcome the resistance of tuber pipe, and then send cold/hot-blast to the end.
