Description

Technical Field

[0001] The present invention relates to the field of new energy and energy-saving technology, and in particular to a refrigeration device and method suitable for low-rise buildings in southern hilly areas. Background Art

[0002] The southern hilly area mainly refers to some low mountain and hilly areas in southeastern China. This area includes part or all of the areas of several provinces. Specifically, it covers part or most of Fujian, Jiangxi, Hunan, Guangdong, Guangxi, etc. The terrain characteristics of these areas are mainly hilly, with a small amount of plains and mountains in between, and the landforms are relatively complex and changeable.

[0003] In terms of climate characteristics, the southern hilly area belongs to the subtropical monsoon climate zone, which mainly exhibits the following characteristics:

[0004] Warm and humid: The temperature is high throughout the year, the frost-free period is long, and the average temperature in the coldest month is generally above 0℃, which is suitable for the growth of a variety of crops.

[0005] Abundant rainfall: Annual precipitation is large, generally between 1,000 mm and 2,000 mm. Precipitation is mainly concentrated in spring and summer, easily forming abundant water resources.

[0006] The four seasons are distinct: warm spring, hot summer, cool autumn and mild winter. The seasonal changes are obvious and the summer lasts longer.

[0007] Abundant sunshine: Despite the abundant rainfall, the sunshine hours are still relatively sufficient, which is conducive to plant photosynthesis.

[0008] Due to its unique geographical environment and climatic conditions, the southern hilly area is very suitable for the development of agriculture, especially the planting of cash crops such as tea trees and fruit trees. In addition, the region also has rich water resources and tourism resources, which has played a positive role in promoting local economic development.

[0009] Geothermal heat pump system, commonly known as ground source heat pump (GSHP), is an efficient energy system used for heating, cooling and hot water supply of buildings. The system takes advantage of the relatively stable temperature within a certain depth below the earth's surface, that is, the temperature underground is higher than the ground temperature in winter and lower than the ground temperature in summer. This temperature difference enables the ground source heat pump to effectively transfer heat from one place to another, achieving the purpose of energy conservation and emission reduction.

[0010] Most of the southern hilly areas have high summer temperatures and long summers. In the summer, air conditioners or geothermal heat pump systems are generally used for cooling in the southern hilly areas. Compared with air conditioners, geothermal heat pump systems reduce energy consumption by exchanging and using shallow geothermal energy. However, geothermal heat pump systems are prone to usage problems due to their long-term contact with water, and have high maintenance costs, making them inconvenient to use. Secondly, geothermal heat pump systems generally use wells to take water for recharging, which poses the risk of groundwater pollution and foundation subsidence. Therefore, the southern hilly areas mainly use air conditioners for cooling, resulting in high energy consumption for cooling in summer. Summary of the invention

[0043] The present invention provides a refrigeration device suitable for low floors in southern hilly areas.

[0044] like Figures 1 to 3 The refrigeration device shown is suitable for low-rise buildings in the southern hilly areas, including a waterproof layer 1, a permeable layer 2, an adjusting water trough 3, a drainage trough 11 and a pipe system 4, wherein the adjusting water trough 3 is arranged on the side of the permeable layer 2 with a higher horizontal height, and the adjusting water trough 3 is connected to the permeable layer 2; the drainage trough 11 is arranged on the side of the permeable layer 2 with a lower horizontal height, and the top side of the permeable layer 2 forms a building space 21, and the building space 21 is used to accommodate houses; the waterproof layer 1 is arranged between the permeable layer 2 and the drainage trough 11, and the two ends of the waterproof layer 1 extend along the permeable layer 2 away from the drainage trough 11 to form a water accumulation space 22, and the permeable layer 2 and the adjusting water trough 3 are both located in the water accumulation space 22; the pipe system 4 adjusts the water trough 3 and the drainage trough 11 respectively, and the pipe system 4 is used to adjust the water level height in the permeable layer 2 through the water level height in the drainage trough 11, so that the water level height in the permeable layer 2 is adjusted according to the real-time temperature.

[0045] The waterproof layer 1 cooperates with the horizontal height of the permeable layer 2 to form a water accumulation space 22 that accommodates the permeable layer 2 and the regulating water tank 3, and then cooperates with the pipeline system 4 to adjust the water level. The temperature of the house in the building space 21 is adjusted with the help of a large amount of water accumulated in the permeable layer 2, and summer cooling is achieved with extremely low energy consumption, which effectively reduces energy consumption, achieves the effect of natural cooling, and can significantly improve living comfort.

[0046] Specifically, the regulating water tank 3 is rectangular, and the depth of the regulating water tank 3 is one meter to one and a half meters; the cross section of the regulating water tank 3 along the horizontal direction is a square, and the width of the regulating water tank 3 is one meter.

[0047] Specifically, the house in the building space 21 is a one-story building or a two-story building.

[0048] The pipeline system 4 includes a water inlet pipe 41 and a float valve 42, both of which are arranged in the regulating water tank 3, and the float valve 42 is connected to the water inlet pipe 41. The float valve 42 is used to control the opening and closing of the water inlet pipe 41 according to the set water level. When the water level in the regulating water tank 3 is lower than the set water level, the water inlet pipe 41 is controlled to replenish water in the regulating water tank 3. The automatic opening and closing of the water inlet pipe 41 is realized by the float valve 42, which is convenient for users.

[0049] The inner wall surface of the regulating water tank 3 is provided with a perforated PVC plate 34. The provision of the perforated PVC plate 34 can ensure the structural strength of the regulating water tank 3 and the exchange efficiency of the water in the permeable layer 2 and the water in the regulating water tank 3.

[0050] The pipeline system 4 further includes a water outlet pipe 43 and a drain valve 44 . The drain valve 44 is disposed on the water outlet pipe 43 . One end of the water outlet pipe 43 is connected to the regulating water tank 3 , and the other end of the water outlet pipe 43 is connected to the drain tank 11 .

[0051] When the water level in the regulating water tank 3 is lower than the water level in the permeable layer 2 in the water accumulation space 22, the water in the permeable layer 2 flows to the regulating water tank 3, and then flows out to the drainage tank 11 through the outlet pipe 43, so that the water level in the permeable layer 2 drops, ensuring that the house in the building space 21 remains relatively dry; when the water level in the regulating water tank 3 is higher than the water level in the permeable layer 2 in the water accumulation space 22, the float valve 42 and the water inlet pipe 41 cooperate to supplement the water in the regulating water tank 3 through the water inlet pipe 41, so that the water in the regulating water tank 3 flows into the permeable layer 2, until the water levels in the regulating water tank 3 and the permeable layer 2 both meet the set water levels, and the first floor of the entire house remains slightly damp, achieving a natural cooling effect.

[0052] A maintenance groove 31 is also provided between the regulating water groove 3 and the drain groove 11, a water outlet pipe 43 passes through the maintenance groove 31, and a drain valve 44 is located in the maintenance groove 31; a detachable mesh cover 45 is provided at one end of the water outlet pipe 43 connected to the regulating water groove 3. The provision of the maintenance groove 31 facilitates the user to use the drain valve 44, and the detachable mesh cover 45 can prevent clogging by mud and sand.

[0053] Specifically, the water outlet pipe 43 is also provided with a water pump, and the water pump is located in the maintenance tank 31 .

[0054] The inner wall surface of the maintenance groove 31 is provided with a prefabricated concrete slab 32. The setting of the prefabricated concrete slab 32 has strengthened the structural strength of the maintenance groove 31, and can prevent the water body of the permeable layer 2 from entering the maintenance groove 31.

[0055] The waterproof layer 1 is a clay layer; the permeable layer 2 is at least one of a silt layer, a fine sand layer, a coarse sand layer or a gravel layer. The clay layer blocks the water accumulation space 22 where the water flows, and the height difference of the permeable layer 2 is combined to facilitate the retention of the water body. The combination of the silt layer, the fine sand layer, the coarse sand layer or the gravel layer can ensure the flow of water vapor between the permeable layer 2 and the house, so as to ensure the cooling effect inside the house.

[0056] The permeable layer 2 is a natural stratum under the foundation, or is constructed by filling at least one of a silt layer, a fine sand layer, a coarse sand layer or a gravel layer. The later constructed permeable layer 2 and the original natural stratum can establish horizontal and vertical hydraulic connections.

[0057] The waterproof layer 1 is a natural stratum under the foundation, or is constructed by a clay layer. The waterproof layer 1 constructed by the clay layer cooperates with the height difference of the permeable layer 2 to form a water accumulation space 22 for accommodating water.

[0058] A plurality of concrete foundations 23 are arranged in the permeable layer 2, and the concrete foundations 23 are arranged in a matrix along the horizontal plane. The arrangement of the concrete foundations 23 can ensure the structural strength of the foundation in the building space 21.

[0059] A breathable layer is arranged on the side of the water-permeable layer 2 facing the building space 21; the breathable layer includes at least one of a clay brick layer or a water-permeable stone layer. The setting of the air field can accelerate the water vapor exchange speed in the house and the water-permeable layer 2.

[0061] Acquire the real-time temperature and the preset temperature value, and control the pipeline system 4 according to the real-time temperature and the preset temperature value;

[0062] When the real-time temperature is greater than or equal to the preset temperature value, the pipe system 4 adjusts the water level in the water tank 3 according to the set water level control, so that the pipe system 4 maintains the water level in the permeable layer 2 to the set water level by adjusting the water tank 3;

[0063] When the real-time temperature is lower than the preset temperature value, the pipe system 4 sends the water in the permeable layer 2 into the drainage groove 11 by adjusting the water groove 3, so that the water level in the permeable layer 2 is lower than the target water level.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
