Description

TECHNICAL FIELD

[0001] The present application relates to the field of new energy and energy-saving technology, and particularly relates to a low-floor refrigeration device and method suitable for southern hilly areas. BACKGROUND

[0002] The southern hilly area mainly refers to some low mountain and hilly areas in the southeast of China. This area includes part or all of several provinces. The topography of these areas is mainly hilly, with a small amount of plains and mountains, and the landform is relatively complex and variable.

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

[0004] Warm and humid: The temperature is relatively high throughout the year, and the frost-free period is long, with an average temperature of 0°C or higher in the coldest month, suitable for the growth of various crops.

[0005] Abundant rainfall: The annual precipitation is large, generally between 1000 and 2000 millimeters, and the precipitation is mainly concentrated in spring and summer, which can form abundant water resources.

[0006] Distinct seasons: The spring is warm, the summer is hot, the autumn is cool, and the winter is warm, with obvious seasonal changes and a long summer.

[0007] Sufficient sunlight: Although the rainfall is abundant, the sunshine hours are still relatively sufficient, which is beneficial to plant photosynthesis.

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

[0009] Geothermal heat pump system, commonly known as ground source heat pump (GSHP), is a kind of high-efficiency energy system for building heating, cooling and hot water supply. The system takes advantage of the relatively stable temperature below the earth's surface, that is, the underground temperature 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 saving and emission reduction.

[0010] Most of the southern hilly areas have high temperature in summer, and the summer time is long. In summer, air conditioning or ground heat pump system is generally used in the southern hilly areas for cooling. Compared with air conditioning, the ground heat pump system reduces energy consumption through the exchange and use of shallow geothermal energy, but the ground heat pump system is prone to use problems due to being in contact with water all year round, and the maintenance cost is high, resulting in inconvenience in use. Secondly, the ground heat pump system generally takes water through well drilling and recharges, which has the risk of groundwater pollution and foundation subsidence. Therefore, air conditioning is still mainly used for cooling in the southern hilly areas, resulting in high cooling energy consumption in summer. SUMMARY

[0011] The main purpose of the present application is to provide a low-floor refrigeration device and method suitable for the southern hilly areas, aiming to solve the problem of high cooling energy consumption in summer in the southern hilly areas.

[0043] The present application proposes a low-floor refrigeration device suitable for hilly areas in southern China.

[0044] As Figures 1 to 3 shown, a low-floor refrigeration device suitable for hilly areas in southern China, comprising a water barrier layer 1, a water permeable layer 2, an adjusting water tank 3, a drainage tank 11 and a pipeline system 4, the adjusting water tank 3 is arranged on the side with higher horizontal height of the water permeable layer 2, and the adjusting water tank 3 is communicated with the water permeable layer 2; the drainage tank 11 is arranged on the side with lower horizontal height of the water permeable layer 2, the top side of the water permeable layer 2 forms a building space 21, which is used for accommodating houses; the water barrier layer 1 is arranged between the water permeable layer 2 and the drainage tank 11, and the both ends of the water barrier layer 1 extend away from the drainage tank 11 along the water permeable layer 2 to form a water accumulation space 22, and the water permeable layer 2 and the adjusting water tank 3 are located in the water accumulation space 22; the pipeline system 4 is arranged in the adjusting water tank 3 and the drainage tank 11, and the pipeline system 4 is used for adjusting the water level in the water permeable layer 2 through the water level in the drainage tank 11, so that the water level in the water permeable layer 2 is adjusted according to the real-time temperature.
