The ground source heat pump is a high-efficiency energy-saving air conditioning system which can supply heat and refrigerate by utilizing underground shallow geothermal resources. The ground source heat pump realizes the transfer of low-temperature heat energy to high-temperature energy by inputting a small amount of high-grade energy. The geothermal energy is used as a heat source for heating by a heat pump in winter and a cold source for an air conditioner in summer respectively, namely, the heat in the geothermal energy is taken out in winter, and after the temperature is increased, the geothermal energy is supplied for indoor heating; in summer, the heat in the room is taken out and released into the earth.
The shallow geothermal energy is used as a clean and renewable energy source and is widely applied to cooling and heating of buildings such as houses, public buildings and the like. However, some projects currently have the problem of unbalanced heat extraction and heat removal after running for a period of time, so that the soil temperature is reduced, and the system running efficiency is poor.

In the past, the temperature of soil can be lower and lower more, even lead to soil temperature too low ground source heat pump unit unable start-up use. In addition, the temperature in the spring and autumn is low in the cold region, so that the heat is not beneficial to the supplement of the heat in the soil, and the cooling requirement in the summer in the cold region is low, so that the heat compensation is an urgent work.
In order to better save the electric power cost, the solar water heater and the solar power generation system are added into the ground source heat pump system, and the solar power generation system can be used for supplying power to the ground source heat pump system and also can be used for supplying power to electric appliances used in daily life, so that more cost is not caused for a long time.
The present application is described in further detail below in conjunction with figures 1 to 4.
In order to improve the working stability of a ground source heat pump system, the application provides a solar-energy-based geothermal energy thermal compensation method.
Referring to fig. 1, a solar-based geothermal energy thermal compensation method includes the steps of:
s101: and acquiring daily heat to be supplemented of the soil side, daily heat discharging of the ground source heat pump system, residual heat of the solar water heater and residual electric quantity of the solar battery.
The daily heat to be supplemented every day is determined by the heat to be supplemented of the ground source heat pump system in a preset period on the soil side, and the preset period comprises a continuous heating season and a continuous cooling season. For example, a winter season is taken as a heating season, and summer season following the winter season is taken as a continuous cooling season following the heating season. The specific implementation mode is as follows: the ground source heat pump system discharges indoor heat to the soil side simultaneously when refrigerating through the air conditioner, and the heat taking amount and the heat discharging amount of the soil side are counted through a cold and hot metering device in the ground source heat pump system. After the soil side accumulated heat extraction amount in the heating season and the soil side accumulated heat extraction amount in the cooling season in one preset period are obtained, the soil side accumulated heat extraction amount in the heating season in the cold region is definitely larger than the soil side accumulated heat extraction amount in the cooling season, so that the temperature reduction of a soil temperature field is necessarily caused, and the condition of heat extraction in the subsequent heating season is not facilitated. Therefore, the soil needs to be supplemented with heat, and the amount of heat to be supplemented is the difference between the accumulated heat-taking amount at the soil side in the heating season and the accumulated heat-discharging amount at the soil side in the cooling season. Further, obtaining daily heat to be supplemented at the soil side comprises: and acquiring the quantity of heat to be supplemented and the number of days of a cooling season of the ground source heat pump system in a preset period on the soil side. And calculating the daily heat to be supplemented according to the heat to be supplemented and the days of the cooling season. Meanwhile, the solar water heater can transfer the heat in the redundant hot water to the soil side for heat compensation after being used at night. Meanwhile, the solar power generation system can be used for supplying power to a house and a ground source heat pump system, and the residual power after power supply is used for the work of the heat supply compensator 204.
S102: and determining the daily heat supplement quantity which is needed to supplement heat to the soil side according to the daily heat supplement quantity, the daily heat removal quantity and the residual heat.
And calculating the sum of the daily heat removal quantity and the residual heat quantity of the solar water heater, and adding more than part of the total heat quantity into the daily heat removal quantity of the next day when the sum is more than the daily heat quantity to be supplemented. When the sum is smaller than the daily heat supplement amount, the difference between the daily heat supplement amount and the sum is the daily heat supplement amount which also needs to supplement heat to the soil side.
S103: the activation time of the thermal compensator 204 is determined according to the solar supplementary heat and the remaining power of the solar cell.
In the present application, the heat supplement amount of each day is divided, and the actual heat supplement amount of each day is composed of three parts, the first part is the daily heat release amount to the soil side when the ground source heat pump system is used for cooling, the second part is the residual heat of the solar water heater, and the third part is the daily heat supplement amount of the heat compensator 204 actively to the soil side. However, the opening of the daily cooling system is determined manually, and the residual heat of the solar water heater needs to be determined only when no person is used at night, so that the daily heat release and the residual heat cannot be accurately estimated. In order to improve the running stability of the system, the daily heat removal amount, the residual heat amount and the daily heat supplement amount of the next day are calculated as one heat supplement unit, and the heat supplement operation in the whole heat supplement season can be considered as long as the heat supplement unit reaches the daily heat supplement amount to be supplemented, and when the calculation is performed in this way, the last day is not supplemented, and the heat supplement is needed to be performed in the day after the cold season. In this way, only the operating efficiency of the thermal compensator 204 at various ambient temperatures and soil temperatures needs to be known, so that the daily on-time of the thermal compensator 204 can be calculated, thereby achieving the heat compensation to the soil side.
First, it is necessary to know the efficiency of thermal compensation at different ambient and soil temperatures. Analysis of historical operating data of the thermal compensator 204 is therefore required. The ambient temperature collected by the climate compensator and the soil temperature are obtained. And retrieving from the database the daily supplementary heat of the thermal compensator 204 to the soil side, and the ambient temperature, the soil temperature corresponding to the date, and the start time and the shut-off time when the thermal compensator 204 corresponding to the date is turned on. And training a working efficiency model of the thermal compensator 204 according to the daily supplementary heat in the historical data, the starting time of the thermal compensator 204, the environmental temperature and the soil temperature of the corresponding date. At this time, the working efficiency model of the thermal compensator 204 is related to the ambient temperature and the soil temperature, and the temperature information is input into the working efficiency model, so that the working efficiency of the thermal compensator 204 can be obtained. Therefore, it is also necessary to obtain the ambient temperature and the weather forecast at the time of operation of the thermal compensator 204, and to obtain future temperature data.
In one implementation, the model is trained by first calculating the relationship between the daily heat supplement, ambient temperature, soil temperature, and start-up and shut-down times of thermal compensator 204 in the historical data. According to the daily heat supplement and the starting time of the thermal compensator 204 corresponding to the date, a first relation coefficient of the daily heat supplement and the environment temperature, the soil temperature and the starting time of the thermal compensator 204 and a second relation coefficient of the daily heat supplement and the soil temperature are determined. The calculation formula of the total heat delivered by the thermal compensator 204 is:wherein->For the on-time of the thermal compensator 204, +.>Is the off time of the thermal compensator 204. And->Is a function of the ambient temperature in relation to the soil temperature,/->；/>In order to be at the temperature of the environment,is the soil temperature. For->The calculation of the parameters of the thermal compensation heat efficiency, the thermal compensation water consumption and the like can also be obtained by a curve fitting mode, and is a technology known in the art, and no further development is performed. Further, a first relation coefficient is determined>，/>For daily heat supplement, a first relation coefficient of daily heat supplement to the ambient temperature, the soil temperature and the activation time of the thermal compensator 204 can be determined from the ratio of the total heat delivered to the daily heat supplement>. Calculate->When the amount of change in (2) is changed, it is necessary to obtain a second relation coefficient of solar heat removal amount and soil temperature from the history data +.>. The calculation formula of the second relation coefficient is as follows: />，/>The soil temperature at which thermal compensator 204 is closed daily. Further, an efficiency curve of the thermal compensator 204 over time is derived from the first relationship coefficient, the second relationship coefficient, the ambient temperature, the weather forecast, and the soil temperature. The curve is integrated to obtain the complementary heat quantity of the thermal compensator 204.
After obtaining the efficiency curve of the thermal compensator 204 over time, the heat compensation amount can be obtained according to the integration, and the starting time of the thermal compensator 204 can be further determined by combining the residual electric quantity of the solar cell.
For the consideration of electricity cost, the implementation of determining the activation time of the thermal compensator 204 in the present application is: the daily time is divided by taking the preset time interval as a reference, the heat compensation quantity and the electricity price of the heat compensator 204 in each time interval are calculated respectively, and a plurality of time intervals with the shortest total time are selected. And then judging the power consumption of the thermal compensator 204 and the residual power of the solar cell at the shortest time intervals when the thermal compensator is used in total. When the electricity consumption of the thermal compensator 204 in the shortest time intervals for completing the total time of solar supplementary heat is less than or equal to the remaining electricity of the solar cell, the time intervals for completing the total time of solar supplementary heat may be directly used as the starting time of the thermal compensator 204. When the electricity consumption of the thermal compensator 204 is greater than the remaining amount of the solar cell at the shortest time intervals when the total daily heat supplement is completed, the utility power is needed, and additional electricity cost is needed to be considered. The method at this time is as follows: the price curve of electricity price along with time is obtained, then the time of day is divided by taking the preset time interval as a reference, and the heat compensation quantity and the electricity price quantity of the heat compensator 204 in each time interval are calculated according to the price curve and the efficiency curve of the heat compensator 204 along with time. And determining the free working time of the thermal compensator 204 according to the residual electric quantity of the solar battery. At this point, the problem of how to calculate the minimum electricity costs needs to be considered. Based on the free operating time, the supplementary heat amount and the electricity price amount of the heat compensator 204 in each time interval, a plurality of time intervals with the lowest additional electricity cost are determined as the on period of the heat compensator 204. One implementation way is as follows: screening all the time intervals capable of completing daily heat supplement as a scheme, further analyzing the schemes, calculating the lowest electricity price of the time intervals exceeding the free working time in each scheme, and sequencing in ascending order. The first scheme is selected as the activation time of the thermal compensator 204. Of course, in order to further reduce the calculation cost, the analysis may also be performed by using a linear regression algorithm or the like.
In the application, another emergency exists, namely when the actual heat supplement quantity on the current day is influenced by weather factors such as rainy days and the like, and the actual heat supplement quantity is smaller than the daily heat supplement quantity, the residual heat supplement quantity is accumulated into the daily heat supplement quantity on the next day. The residual heat quantity to be supplemented is determined by the difference between the actual heat supplementing quantity and the daily heat supplementing quantity.
The application provides a geothermal energy thermal compensation system based on solar energy, adopts following technical scheme:
referring to fig. 2 and 3, a solar-based geothermal energy thermal compensation system includes:
the acquisition module 201 is configured to acquire daily heat to be supplemented on the soil side, daily heat discharged on the ground source heat pump system, residual heat of the solar water heater and residual electric quantity of the solar battery.
