Embodiment 1

[0016] Please refer to figure 1 , is a structural schematic diagram of the first embodiment of the ground source heat pump system of the present invention. The working principle of the ground source heat pump system is as follows: first, the compressor 2 in the ground system sucks the low-temperature and low-pressure gaseous refrigerant from the evaporator 1, and compresses it into a high-temperature and high-pressure gaseous refrigerant, and the high-temperature and high-pressure gaseous refrigerant The gaseous refrigerant enters the condenser 4. In the condenser 4, the high-temperature and high-pressure gaseous refrigerant is cooled with the cooling refrigerant from the underground tube coil system 5. The cooled refrigerant flows through the thermal expansion valve (capillary tube )3, throttling into a low-temperature and low-pressure gas-liquid two-phase refrigerant, and then the low-temperature and low-pressure refrigerant absorbs heat from the outside in the evaporator 1 ...

The ground source cold storage device according to the embodiment of the present invention includes an underground cooling tube-coil heat exchange unit 8 for a cold storage working medium and a liquid cold storage working medium 7 .

[0021] The liquid cold storage working medium 7 is located in the underground soil. In this embodiment, the cold storage working medium 7 may be a liquid substance such as water with a large specific heat capacity.

[0022] The underground cooling tube-coil heat exchange unit 8 is located in the liquid cold storage working fluid 7 and partly exposed on the ground, so as to realize cold storage of the cold storage working fluid. In this embodiment, firstly, the gravitational heat pipe (hereinafter referred to as the gravity heat pipe) of the cold storage medium underground cooling tube coil ...

Embodiment 3

[0028] It should be noted that the ground source cold storage device of the present invention can be applied to various heat exchange systems, such as air conditioners, telecommunication equipment rooms, etc.

[0029] Please refer to image 3 , is a schematic structural diagram of a ground source cold storage system including a ground source cold storage device according to an embodiment of the present invention. The system includes a ground source cold storage device 23, and the specific structure of the ground source cold storage device 23 is the same as that of the ground source cold storage device in the second embodiment.

[0030] The system further comprises an air conditioning unit 22 and a heating device 21,

[0031] In this embodiment, the thermal device 21 may be an electronic device or a communication device, etc.;

[0032] In this embodiment, the air conditioner 22 is used to adjust the temperature of the thermal equipment 21;

[0033] In this embodiment, the gr...

Abstract

The embodiment of the invention discloses a ground source cold accumulation device and a ground source cold accumulation system. The ground source cold accumulation device comprises a liquid cold accumulation working substance and an underground cooling coil heat exchange unit, the liquid cold accumulation working substance is positioned in underground soil, the underground cooling coil heat exchange unit is positioned in the liquid cold accumulation working substance and is partially exposed on the ground, realizing the cold accumulation of the cold accumulation working substance. The cold accumulation of the cold accumulation working substance is performed through the underground cooling coil heat exchange unit, and the cold accumulation capability and the heat exchange capability of unit space are enhanced through the liquid cold accumulation working substance. The accumulated cold capability of the cold accumulation working substance can be used as the cold ends of air conditioning devices and other heat exchange systems, and the ground source cold accumulation device has simple structure, stable and reliable operation and high efficiency and is environmental friendly.

Description

technical field [0001] The invention relates to cold storage technology, in particular to a ground source cold storage device and system. Background technique [0002] Ground source heat pump technology is a new type of heat pump technology that uses the energy of shallow normal-temperature soil or groundwater as an energy source, which is highly efficient and energy-saving, and has low operating costs. It can be used for heating and cooling and can provide domestic hot water. It is efficient, energy-saving and conducive to sustainable development. Ground source heat pump technology utilizes the characteristics of relatively stable temperature of underground soil, surface water, and groundwater. Driven by electric energy, it transfers heat from low-level heat sources to places that need heating or heating in winter, and uses ground source heat pump air conditioners in summer. The heat in the room is transferred to the underground soil or groundwater to achieve the purpose o...
