Description

Water supplementing device for closed air conditioner water system

Technical Field

The utility model relates to a moisturizing device for closed air conditioner water system belongs to closed air conditioner water system moisturizing technical field.

Background

At present, closed air-conditioning water systems in air-conditioning professional design drawings generally supplement water through an expansion water tank, and the water inlet of the expansion water tank is supplemented with water through a domestic water supply system. The expansion tank also plays a role in exhausting and pressure-fixing in the closed air-conditioning water system. Before the closed air-conditioning water system is debugged and during water replenishing after the system is emptied, the system pipeline is full of air, and water can be filled in the system only by discharging the air of the pipeline. If adopt expansion tank direct moisturizing to have following problem:

1. because expansion tank's water level difference is too little, the air in the system's pipeline can't discharge through discharge valve fast, and system's moisturizing is slow, and a system's moisturizing is more than three days at least, can't fill in water even.

2. Before the system is debugged, if the expansion water tank is adopted for water supplement, the water supplement of the system is slow, workers are involved, and the labor cost is increased.

3. When the system is cleaned regularly after being put into use, if the expansion water tank is used for replenishing water, the water replenishing of the system is slow, the management cost of a property company is increased, and the air conditioner cannot be put into use in time, so that the influence is caused.

4. When the water pressure and the water quantity in the air-conditioning water system behind the expansion water tank are insufficient, the water supplementing speed of the expansion water tank cannot keep up with the water using speed in the system, so that the system is unstable in operation, and the air-conditioning refrigeration effect is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a simple structure, installation are swift, control is simple be used for closed air conditioner water system's moisturizing device, and the device improves expansion tank's moisturizing efficiency, prevents that air conditioner water system from lacking water and influencing the refrigeration effect.

The technical scheme of the utility model is realized like this: the utility model provides a moisturizing device for closed air conditioner water system, includes expansion tank, is connected with inlet tube and expansion pipe respectively on the upper portion and the lower part of expansion tank one side, is connected with communicating pipe between inlet tube and expansion pipe, is connected with breather pipe and drain pipe respectively in the top and the bottom of expansion tank's opposite side, installs first solenoid valve, second solenoid valve and third solenoid valve respectively on inlet tube, expansion pipe and communicating pipe, installs the drain valve on the drain pipe.

Furthermore, the upper part of the expansion water tank is connected with an overflow pipe, and the outlet end of the overflow pipe is connected with a drain pipe.

Since the technical scheme is used, the utility model has the advantages that: the utility model discloses pass through communicating pipe and expansion pipe intercommunication with expansion tank's inlet tube, cross expansion tank, through the water pipe that has the pressure directly for air conditioner water system moisturizing, make the air in the pipeline discharge through discharge valve fast, shorten system's moisturizing time greatly.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides a: referring to fig. 1, a moisturizing device for closed air conditioner water system, including expansion tank 7, upper portion and lower part in expansion tank 7 one side are connected with inlet tube 1 and expansion water pipe 2 respectively, be connected with communicating pipe 3 between inlet tube 1 and expansion water pipe 2, top and bottom at expansion tank 7's opposite side are connected with breather pipe 8 and drain pipe 9 respectively, at inlet tube 1, install first solenoid valve 4 on expansion water pipe 2 and communicating pipe 3 respectively, second solenoid valve 5 and third solenoid valve 6, install drain valve 10 on drain pipe 9. The upper part of the expansion water tank 7 is connected with an overflow pipe 11, and the outlet end of the overflow pipe 11 is connected with a drain pipe 9.

The utility model discloses a theory of operation:

the inlet pipe 1 is first connected to an external tap water pipe, while the expansion water pipe 2 is connected to the water collector. When the closed air-conditioning water system needs water supplement, the first electromagnetic valve 4 on the water inlet pipe 1 and the second electromagnetic valve 5 on the expansion water pipe 2 are closed through BA control, the third electromagnetic valve 6 on the communicating pipe 3 is opened, and water is directly supplemented to the closed air-conditioning water system through tap water.

When closed air conditioning water system stopped, through BA control, open first solenoid valve 4 on inlet tube 1 and the second solenoid valve 5 on the expansion pipe 2, close third solenoid valve 6 on communicating pipe 3, stop to the moisturizing of closed air conditioning water system.

To sum up, the utility model discloses with expansion tank's inlet tube 1 through communicating pipe 3 and expansion pipe 2 intercommunication, cross expansion tank, directly give air conditioner water system moisturizing through the water pipe that has the pressure, make the air in the pipeline discharge through discharge valve fast, shorten system's moisturizing time greatly.
