Description

A geothermal water conditioner

technical field

The utility model belongs to the technical field of indoor air temperature adjustment, in particular to a ground temperature water air conditioner which uses perennial constant temperature ground temperature water as a heat conducting medium.

Background technique

As one of the important members of people's household appliances, air conditioners can cool in summer and heat in winter. In real life, if people want to keep the indoor temperature suitable in four seasons, people have to bear expensive electricity bills. Refrigerant freon in air conditioners is also very damaging to the earth's atmosphere. The air conditioner can be said to be a kind of electrical equipment with high power consumption and high pollution.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a low-power, energy-saving and environment-friendly ground temperature water air conditioner.

In order to realize the purpose of the present invention, the specific solution is: a ground temperature water air conditioner, comprising an air conditioner indoor unit, heat exchange pipeline, exhaust fan, U-shaped sealed water pool, upper water pipe, return water pipe, water pump, characterized in that: the water pump and The upper water pipe is connected to one side of the U-shaped sealed pool, and the other side is provided with a return pipe. The air-conditioning indoor unit is a box body with two openings around it, and an exhaust fan is installed at one opening end. The heat exchange pipe The pipeline is arranged inside the indoor unit of the air conditioner, and the water supply pipe and the water return pipe are respectively connected with the water inlet and water outlet of the heat exchange pipeline. The bottom of the aforementioned U-shaped sealed pool is arranged 5 meters below the ground.

The year-round temperature at a depth of 3 meters below the surface is about 17.5°C, while the air temperature contrast between winter and summer is about 50°C, the indoor temperature is about -14°C in winter, and the hot and high temperature in summer is about 38°C. In winter, indoor and ground temperature water The temperature difference is about 30°C, and the temperature difference between indoor and ground water is 13°C to 21°C in summer. The function of the ground temperature water air conditioner is to use the ground temperature as the heat resource, and rely on water as the heat exchange medium to exchange heat between the indoor temperature and the ground temperature.

In summer, when the ground temperature water air conditioner works for refrigeration, the water pump pumps the water in the underground U-shaped sealed pool to the heat exchange pipeline through the upper water pipe. While on the road, the temperature of the water is also around 17.5°C. Compared with room temperature, it is 13°C to 21°C lower. The exhaust fan exhausts the air cooled by the heat exchange pipeline into the room to achieve the purpose of cooling the room. The water passing through the heat exchange pipeline returns to the return water side of the underground U-shaped sealed pool through the return water pipe. At the same time, the temperature of the water returning to the return water side also rises. The water returning to the backwater side of the underground U-shaped sealed pool begins to cool down through the ground temperature, and the cooled water flows into the upper water side of the underground pool through the bottom passage, and is ready to be pumped up again by the water pump.

The heating process of the geothermal water conditioner in winter is similar to the cooling process in summer, and will not be repeated here.

The electrical equipment of the whole machine is the water pump and exhaust fan. Since the height of the return water pipe is equal to that of the upper water pump, they are all below the water surface. There is no water level drop. The inner diameter of the entire pipeline is the same, and there is no resistance like the capillary of ordinary air conditioners. , so the water pump does not need too much power to complete the water cycle, and the power consumption of the whole machine is about 100W.

Detailed ways

A geothermal water air conditioner, comprising an air conditioner indoor unit 1, a heat exchange pipeline 2, an exhaust fan 3, a U-shaped sealed pool 4, an upper water pipe 5, a return water pipe 6, and a water pump 7, and the water pump 7 is connected to the upper water pipe 5 and placed in the U One side of the type sealed pool 4, and the other side is provided with a return pipe 6, the air-conditioning indoor unit 1 is a box body with two openings around it, and an exhaust fan 3 is provided at the opening end of one side, and the heat exchange pipeline 2 Located inside the air-conditioning indoor unit 1, the upper water pipe 5 and the return water pipe 6 communicate with the water inlet and the water outlet of the heat exchange pipeline 2 respectively, and the bottom of the aforementioned U-shaped sealed pool 4 is located 5 meters below the ground.

In summer, when the ground temperature water air conditioner works for refrigeration, the water pump 7 pumps the water in the underground U-shaped sealed pool 4 into the heat exchange pipeline 2 through the upper water pipe 5. At this time, the water temperature on the upper water side of the U-shaped sealed pool 4 is about 17.5°C. When it is sent to the heat exchange pipeline 2, the temperature of the water is also about 17.5°C, which is 13°C to 21°C lower than the room temperature, and the exhaust fan 3 will discharge the air cooled by the heat exchange pipeline 2 into the room. Get the purpose of indoor cooling. The water passing through the heat exchange pipeline 2 returns to the return water side of the underground pool through the return water pipe 6. At the same time, the temperature of the water returning to the return water side also rises. Get back to the water on the backwater side of the underground U-shaped sealed pool 4 and start to cool down through the ground temperature, and the cooled water flows into the upper water side of the underground pool through the bottom passage, and is ready to be pumped up again by the water pump.

The heating process of the geothermal water conditioner in winter is similar to the cooling process in summer, and will not be repeated here.

Claims (2)
