Problems solved by technology

Since building A and building B adopt their own independent geothermal HVAC systems, the users of building A do not get enough heat, while the users of building B get too much heat
In this case, it is impossible to achieve a reasonable allocation of heat energy usage in the geothermal HVAC heating system, and thus cannot meet the actual needs of users.

Embodiment 1

[0053] Please refer to the attached figure 1 , which shows the flow of the method for controlling geothermal use of multiple buildings provided by Embodiment 1 of the present invention.

[0054] figure 1 In the control method shown, each building is equipped with a geothermal heating, ventilation and air-conditioning system that provides thermal energy for users of the building, and the control method includes the following steps:

[0055] S101. Obtain the required heat consumption of each building within a unit time period.

[0056]In step S101, the required heat consumption of each building within a unit time period is obtained, and the required heat consumption in this step refers to the geothermal energy that can meet the actual heat consumption demands of all users of the building. In the process of acquisition, a specific acquisition method is: you can check the heat consumption of the building in the past unit time period, take the maximum value of the heat consumptio...

Embodiment 2

[0065] Please refer to the attached figure 2 , which shows the flow of the method for controlling the use of geothermal heat in multiple buildings provided by Embodiment 2 of the present invention.

[0066] figure 2 The process shown is to obtain the required heat consumption of each building in a unit time period, including:

[0067] S201. Periodically detect the amount of hot water entering each user in each building within a unit time period, as well as the user's inlet water temperature and outlet water temperature.

[0068] The hot water provided by the geothermal HVAC system enters the user's room and is discharged after exchanging heat with the indoor air. The user's inlet water temperature and outlet water temperature are calculated. During the detection process, multiple sets of data can be detected for calculation.

[0069] S202. Calculate the heat consumption of each user within a unit time period, and calculate the average value of the heat consumption calcul...

Embodiment 3

[0075] Please refer to the attached image 3 , which shows the flow of the method for controlling the use of geothermal heat in multiple buildings provided by Embodiment 3 of the present invention.

[0076] image 3 The process shown is to obtain the required heat consumption of each building in a unit time period, including:

[0077] S301. Obtain the heating area of ​​each user in each building.

[0078] In the process of obtaining, it is necessary to obtain the indoor area that each user actually needs to heat.

[0079] S302. Obtain the preset heat supply per unit area of ​​each user in each building.

[0080] This step obtains the preset heat supply per unit area according to the actual regional environment and the heating temperature standard.

[0081] S303. Calculate the heat consumption of each household according to the heating area and the preset heat supply per unit area.

[0082] Heat consumption per household = heating area * preset heat supply per unit area. ...

Abstract

The invention discloses a geothermal use control method for many buildings, each building is provided with a geothermal heating ventilation air conditioning (HVAC) system for offering thermal energy for the user for the building, the method comprises the steps as follows: obtaining the quantity of heat required by each building in unit of time and the heat supplied quantity of the geothermal HVAC system for offering thermal energy for the building; calculating the difference value between the heat supplied quantity of the geothermal HVAC system in unit of time and the required quantity of heat for the building in unit of time; replenishing the surplus thermal energy of the geothermal HVAC system corresponding to the positive difference value for the geothermal HVAC system corresponding to the negative difference value. The geothermal use control method for many buildings can mutually complement the thermal energy for many buildings, and the method can reasonably distribute the geothermal energy according to the requirement of the user. A geothermal use control system for many buildings is also provided.

Description

technical field [0001] The invention relates to the technical field of geothermal energy utilization, in particular to a method and system for controlling the utilization of geothermal energy in multiple buildings. Background technique [0002] Geothermal energy is natural heat drawn from the earth's crust. Geothermal energy belongs to clean and renewable energy, which is more and more widely used by people. People use geothermal energy in a variety of ways, such as building hot springs in areas rich in geothermal energy, heating residents in communities through geothermal energy, and using geothermal energy for geothermal power generation. [0003] With the development of society, it is an inevitable trend of the current society to establish a new type of community that is economical, environmentally friendly and low-carbon. For this reason, in areas rich in geothermal energy, people have established geothermal HVAC systems in communities to provide heating for residents ...
