Abstract

The utility model discloses a device for circular utilizing underground water, which comprises a temperature controller 1. The temperature controller 1 is connected with a temperature sensing probe 2 and an electromagnetic valve 3 which are connected through a water return pipeline 10, and the water return pipeline 10 is led into a water return well 6. The water return pipeline 10 between the temperature sensing probe 2 and the electromagnetic valve 3 is connected with a water inlet pipeline 11 through a bypass pipeline 13, and the water inlet pipeline 11 is connected with a water supply pump 9 and communicated with a water storage tank 5. A liquid level control valve 4 is arranged on the water storage tank 5 and connected with a diving pump 7 through a water taking pipeline 12, and the diving pump 7 is communicated with a water taking well 8. The utility model saves resource and can ensure the normal running of an air conditioner.

Description

The recycling device of a kind of underground water

The utility model relates to a kind of central air-conditioning EGR, relates in particular to a kind of central air-conditioning with underground water circulation use device.

At present air-conditioned room adopt underground water carry out summer refrigeration and winter heating in, by the quantitative groundwater abstraction of water pump, after heat exchange finishes,, all directly enter undergroundly regardless of underground water variations in temperature at this moment, have following shortcoming like this:

(1) when air conditioner load is very little, do not make full use of phreatic cold (summer) or heat energy (winter), directly underground water is entered undergroundly, cause the underground water serious waste.

(2) in operation of air conditioner, when very big, then can cause the ground water supply deficiency as if required underground water internal circulating load, so that cutout, thereby cause operation of air conditioner undesired.

(3) heating operating mode when underground water temperature is not enough, can cause operation of air conditioner undesired.

The utility model purpose is to overcome the deficiency of above-mentioned prior art and a kind of recycling device of underground water that economizes on resources and can ensure the normal operation of air-conditioning is provided.

The purpose of this utility model can reach by following measure: the recycling device of a kind of underground water, it comprises temperature controller, connect a temperature-sensing probe on the temperature controller, connect a magnetic valve simultaneously, temperature-sensing probe, magnetic valve links to each other by water return pipeline, water return pipeline feeds in the back water well, temperature-sensing probe is connected with inlet pipeline by bypass line with water return pipeline between the magnetic valve, inlet pipeline links to each other with feed pump, communicate with storage tank again simultaneously, storage tank is provided with fluid level control valve, and fluid level control valve links to each other with immersible pump by the water intaking pipeline, and immersible pump communicates with water intake well.

The utility model can produce following good effect compared with the prior art:

(1) because the utility model is provided with temperature controller, makes backflow underground water recycling in certain temperature range, thereby saved groundwater resources.

(2) because the utility model is provided with storage tank and fluid level control valve, makes and in operation of air conditioner, satisfy the underground water supply, normal operation is protected.

(3) heating operating mode when underground water temperature is not enough, can be utilized the auxiliary thermal source heat make-up in storage tank, thereby guarantees that air-conditioning normally moves.

Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:

Accompanying drawing is a structural representation of the present utility model;

Embodiment: the recycling device of a kind of underground water (referring to accompanying drawing), it comprises temperature controller 1, connect a temperature-sensing probe 2 on the temperature controller 1, connect a magnetic valve 3 simultaneously, temperature-sensing probe 2, magnetic valve 3 links to each other by water return pipeline 10, water return pipeline 10 feeds in the back water well 6, temperature-sensing probe 2 is connected with inlet pipeline 11 by bypass line 13 with water return pipeline 10 between the magnetic valve 3, bypass line 13 can be established a triple valve with the junction of water return pipeline 10, feed pump 9 communicates with storage tank 5 by inlet pipeline 11 again, bypass line 13 can join with inlet pipeline 11, also can join with inlet pipeline 11 by receiving in the storage tank 5, storage tank 5 is provided with fluid level control valve 4, and fluid level control valve 4 links to each other with immersible pump 7 by water intaking pipeline 12, immersible pump 7 communicates with water intake well 8, and immersible pump 7 also can be placed on outside the water intake well 8.

During use, inlet pipeline 11 of the present utility model is linked to each other with the heat-exchange device of central air-conditioning with water return pipeline 10, the water that storage tank is 5 li carries out heat exchange by feed pump 9 and finishes the back when temperature-sensing probe 2 refluxes, temperature-sensing probe 2 is passed to temperature controller 1 to the temperature signal that records, temperature controller 1 is compared this temperature signal with design temperature: in the winter time during heating, design temperature T (being generally 5-9 ℃), when temperature signal during more than or equal to T, magnetic valve 3 cuts out, backflow underground water bypass is circulated again back into water lines 11, during less than T, magnetic valve 3 is opened, and it is entered in the back water well 6 until backflow underground water temperature; When freezing summer, design temperature T ' (being generally 25-32 ℃) is when temperature signal during smaller or equal to T ', magnetic valve 3 cuts out, and backflow underground water bypass is circulated again back into water lines 11, until backflow underground water temperature during greater than T ', magnetic valve 3 is opened, and it is entered in the back water well 6.The liquid level of fluid level control valve 4 perception storage tanks 5 is lower than when setting liquid level simultaneously, and immersible pump 7 is opened and drawn water from water intake well 8, makes the liquid level of storage tank 5 reach the setting liquid level.
