Embodiment 1

[0075] This embodiment mainly introduces the specific structure, operation mode and characteristics of the present invention.

[0076] Such as image 3 As shown, it is a typical refrigeration working condition of the present invention, wherein the application system 4 is a heat pump system:

[0077] Summer: The initial value of the underground rock and soil temperature is T1=18°C; at this time, the temperature of the heat exchange medium 5 in the energy storage buried pipe 1a is usually slightly higher than the temperature of the surrounding underground rock and soil;

[0078] The heat exchange medium 5 in the energy storage underground pipe 1a is quickly extracted through the quick extraction device 2a, and the extraction temperature is about 21°C; the extracted heat exchange medium 5 is transported to the heat exchange subsystem 3 through pipelines for heat exchange The other side of the heat exchange subsystem 3 is connected to the application system 4 (heat pump system), ...

Embodiment 2

[0104] In the prior art, the insufficient area suitable for buried pipes in the construction area is a big problem. Therefore, a scheme of using building pile foundations to implement pile foundation buried pipes, that is, the energy pile system, has emerged. Energy piles refer to the pile foundations that bury closed heat exchange pipes in the foundation piles (or underground diaphragm walls) of buildings to exchange heat with rock and soil, and undertake the dual functions of structure and heat transfer at the same time (see reference 1 for details) .

[0105] Similar to the existing energy pile system, using the pile foundation to realize the energy storage buried pipe of the present invention is a solution that kills two birds with one stone, and is also an important way to implement the present invention. Therefore, in this embodiment, the prestressed pipe pile is used as the energy storage underground pipe 1a, so that the prestressed pipe pile has dual functions of build...

Embodiment 3

[0125] This embodiment is a combination of the energy storage buried pipe heat exchange system and the valley electricity energy storage to form the valley electricity energy storage composite system:

[0126] The system includes an energy storage buried pipe array 1, a rapid replacement subsystem 2, a heat exchange subsystem 3, and a valley electricity cooling / heating system 8; the valley electricity refrigeration / heating system 8 is an air-cooled heat pump unit, Water-cooled heat pump unit or electric heating unit.

[0127] The off-peak power cooling / heating system 8 operates during the off-peak power period to supply energy to the energy storage buried pipe array 1 and the underground rock and soil mass. When the off-peak power refrigeration / heating system 8 is running, the energy storage buried pipe array 1 passes The rapid replacement subsystem 2 and the heat exchange subsystem 3 are connected to the off-peak electricity cooling / heating system 8, and the off-peak electric...

Abstract

An energy storage type buried pipe heat exchanging system is characterized by comprising energy storage type buried pipe arrays (1), a rapid replacement subsystem (2) and a heat exchanging subsystem (3). By improving the stored energy of buried pipes, the heat exchanging capacity and the adaptive capacity of a buried pipe heat exchanger are enhanced; and by reasonably scheduling the energy storagetype buried pipe arrays, optimized utilizing of the heat exchanging capacity of the energy storage type buried pipes is achieved, and continuous and efficient running of the system is guaranteed.

Description

technical field [0001] The invention relates to a buried pipe heat exchange system, which enhances the heat exchange capacity and adaptability of the buried pipe heat exchanger by increasing the energy storage capacity of the buried pipe, and realizes the buried pipe exchange through reasonable scheduling of the buried pipe array. Optimal utilization of thermal capacity to ensure continuous and efficient operation of the system belongs to the technical field of heat pump or HVAC system design and manufacture. Background technique [0002] Building energy consumption refers to the energy consumption during building use, including heating, air conditioning, lighting, hot water, household appliances and other power consumption. Among them, heating and air conditioning energy consumption is the main energy consumption, accounting for 50% to 70% of the total building energy consumption. How to reduce the utilization of primary high-grade energy is a key technical issue in design...
