specific Embodiment approach 1

[0013] Specific implementation mode one: refer to figure 1 , this embodiment includes a refrigeration equipment composed of a compressor 25, a condenser 26, a throttle valve 27 and an evaporator 28, a cooling tower 29 and a water pump. Each connecting pipeline 32 is connected with a valve, and it also includes an underground buried pipe heat exchanger 33, and the water inlet and outlet of the underground buried pipe heat exchanger 33 are respectively provided with a water collector 34 and a distribution pipe. Water container 35;

[0014] Between the condenser 26 of the refrigerating equipment and the cooling tower 29, between the condenser 26 and the underground pipe heat exchanger 33, between the condenser 26 and the user 31, a loop is formed through pipeline connections; the evaporator 28 and the The users 31, the evaporator 28 and the underground pipe heat exchanger 33 are all connected to form a loop through pipelines; the underground pipe heat exchanger 33 and the user 3...

specific Embodiment approach 2

[0024] Specific implementation mode 2: Since the system fully integrates the advantages of the technical elements of cold storage technology and soil-coupled heat pump technology, it should give full play to the advantages of cold storage technology and make full use of the power resources in low-peak periods when the air conditioner is running in summer. Avoid peak power consumption, cut peaks and fill valleys, reduce system operating costs, store all or part of the air-conditioning cooling capacity used by buildings in the underground soil, and realize the transfer of air-conditioning power loads.

[0025] This implementation mode is the soil cold storage operation mode, which can be selected to work during low power consumption periods. At this time, the low-temperature freezing liquid is prepared by controlling the switches of the valves at different positions, and the low-temperature freezing liquid is circulated in the pipeline of the buried pipe heat exchanger 33 to exch...

specific Embodiment approach 3

[0032] Specific implementation mode 3: This implementation mode is the soil cooling operation mode, and it can be selected to work during peak hours of electricity consumption. During the power peak period, the chiller is shut down, and the brine (antifreeze) is circulated in the underground pipe heat exchanger 33 by turning on the circulating water pump on the side of the user 31, and the cold energy stored in the soil during the low valley period is extracted. For air conditioning system use.

[0033] refer to image 3 , the opening and closing of the valve during this working process is:

[0034] Close No. 1 valve 1, No. 2 valve 2, No. 14 valve 14, No. 19 valve 19, No. 17 valve 17, No. 12 valve 12, No. 21 valve 21 and No. 22 valve 22, and close No. 13 valve 13 and No. 15 Valve 15, valve 20, valve 20, valve 24, valve 24, valve 23, valve 18, valve 16 and valve 16 are opened, even if the loop between the buried pipe heat exchanger 33 and the user 31 is unblocked;

Description

technical field [0001] The invention relates to an integrated system with dual functions of soil cold storage and soil source heat pump. Background technique [0002] Because of the use of renewable geothermal energy, the soil coupled heat pump system is known as one of the most promising refrigeration and air-conditioning technologies in the 21st century with energy-saving and environmental protection significance. The cold storage technology is an air-conditioning technology that changes the power consumption mode of the power demand side and is rapidly developed under the situation of balancing the peak and valley loads of the power grid and peak load and valley filling in order to alleviate the tense situation of power supply. Therefore, the cold storage technology that adapts to the macro-control policy of the national power demand side, the sustainable development theory of energy, and the soil-coupled heat pump technology that utilizes renewable energy have become the...
