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.
The application is described in further detail below with reference to fig. 1 to 4.
In order to improve the working stability of a ground source heat pump system, the application provides a seasonal geothermal energy thermal compensation method.
Referring to fig. 1, a season-based geothermal energy thermal compensation method includes the steps of:
s101: and acquiring the heat extraction quantity and the heat extraction quantity of the ground source heat pump system in a preset period on the soil side.
Wherein the preset period includes one continuous heating season and 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 concrete implementation mode is that 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.
S102: and determining that the heat extraction amount of the ground source heat pump system in a preset period is larger than the heat extraction amount.
After the soil side accumulated heat taking amount in the heating season and the soil side accumulated heat discharging amount in the cooling season in a preset period are obtained, the soil side accumulated heat taking amount in the heating season and the soil side accumulated heat discharging amount in the cooling season need to be judged, and when the soil side accumulated heat taking amount in the heating season is larger than the soil side accumulated heat discharging amount in the cooling season, the condition that the temperature of a soil temperature field is reduced and the heat taking in the subsequent heating season is unfavorable is indicated. 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.
S103: and according to the heat quantity to be supplemented, supplementing heat to the soil side after a preset period.
First, it is necessary to know the efficiency of thermal compensation in the case of different ambient temperatures, soil temperatures and operating durations. It is therefore necessary to analyze the historical operating data of the thermal compensator 204. The ambient temperature collected by the climate compensator and the soil temperature are obtained. And retrieving daily supplementary heat and accumulated supplementary heat of the soil side by the thermal compensator 204 from the database, and the ambient temperature and soil temperature corresponding to the date, and the starting temperature, starting time and closing time when the thermal compensator 204 corresponding to the date is started.
Specifically, the daily supplementary heat is determined based on the accumulated supplementary heat of the thermal compensator 204 to the soil side in the history data. The daily heat supplement, ambient temperature, soil temperature, and start-up time, and shut-down time are used to analyze the relationship between the daily heat supplement and ambient temperature, soil temperature, and the time that thermal compensator 204 is on. Therefore, according to the daily heat supplement and the start-up time of the thermal compensator 204 corresponding to the date, a first relation coefficient of the daily heat supplement and the ambient temperature, the soil temperature and the start-up 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,/->；/>For ambient temperature->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 is not further developed here. Further, a first relation coefficient number 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 temperature of the soil at which thermal compensator 204 ceases to operate daily.
And then determining the starting temperature of the thermal compensator 204 when the thermal compensator is started according to the soil temperature and the pre-stored temperature difference value. The starting temperature changes along with the change of the soil temperature and is also influenced by the change of the pre-stored temperature difference value. And (3) the temperature information of the last complementary heat quarter before the preset period is called to generate a preset temperature curve, wherein the ambient temperature at a time point is taken as the ambient temperature of the corresponding date of the current complementary heat quarter. And finally, calculating a heat compensation period according to the first relation coefficient, the second relation coefficient, the preset temperature curve and the soil temperature.
The process of calculating the complementary heat period comprises the following steps: firstly, calculating theoretical daily supplementary heat according to a preset temperature curve, soil temperature and a first relation coefficient. According to the theoretical daily heat supplement and the second relationship coefficient, the soil temperature at which the daily heat compensator 204 is turned off is determined. Taking the change of the soil temperature into consideration, obtaining a curve of the change of the temperature difference along with time according to the soil temperature and a preset temperature curve, and obtaining theoretical daily supplementary heat by using the curve of the change of the temperature difference along with time, namely, taking the curve of the change of the temperature difference along with time into a calculation formula of the total heat transported by the thermal compensator 204, and obtaining the theoretical daily supplementary heat according to a first relation coefficient. And finally, calculating the total number of days when the accumulated supplementary heat reaches more than the theoretical supplementary heat as a supplementary heat period.
After the heat compensation period is calculated, the heat compensation parameters of the subsequent thermal compensator 204 need to be redetermined according to the actual accumulated heat compensation amount.
Here, the subsequent supplementary heating parameters are determined in two ways, one being to adjust within the present supplementary heating quarter and one being to adjust in the next supplementary heating quarter. When the next complementary heat season is compensated, heat lost in the complementary heat season needs to be accumulated into heat to be compensated in the next complementary heat season, and the mode can more effectively utilize the period with higher temperature in the complementary heat season. When the compensation is performed in the present compensation season, the compensation period is prolonged according to the actual accumulated compensation amount and the compensation amount of the deficiency calculated by the amount to be compensated.
The application provides a seasonal geothermal energy thermal compensation system, which adopts the following technical scheme:
referring to fig. 2 and 3, a season-based geothermal energy thermal compensation system, comprising:

The judgment module 202 determines that the heat extraction amount of the ground source heat pump system in the preset period is greater than the heat extraction amount.
The adjusting module 203 is configured to supplement heat to the soil side after a preset period according to the amount of heat to be supplemented. Wherein the heat quantity to be complemented is determined according to the difference value of the heat taking quantity and the heat discharging quantity.
