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 low-temperature 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 particular to residential buildings in cold areas, the heat extracted from the soil by the ground source heat pump system in winter heating is far greater than the heat discharged from the soil by refrigerating in summer, so that the temperature of the soil is obviously reduced, the heat supply capacity of the ground source heat pump unit is reduced when the heat is supplied in winter, the power consumption of the unit is increased, and the energy consumption of the system running in winter is increased. 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.
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 shallow geothermal energy thermal compensation method.
Referring to fig. 1, a shallow geothermal energy thermal compensation method includes the following steps:
s101: and acquiring the heat to be supplemented 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 firstly, 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.
S102: and calculating the daily heat to be supplemented according to the heat to be supplemented and the days of the cooling season.
The spring and autumn in the cold region are colder, so that the heat supplementing work is not facilitated, and the time length of the cold supply season can meet the heat supplementing requirement in most cases, so that the number of days of the cold supply season is also taken as the number of days of the heat supplementing. Further, dividing the heat to be supplemented by the number of days for the cold season to obtain the average heat to be supplemented.
S103: and according to the daily heat supplement, supplementing heat to the soil side in the next cooling season after the preset period.
In the present application, the daily heat supplement amount is divided, and the daily actual heat supplement amount is composed of two parts, one part is the daily heat discharge amount to the soil side when the ground source heat pump system is cooling, and the other part is the daily heat supplement amount to the soil side by the heat compensator 203. However, the opening of the daily cooling system is manually determined, and thus, the daily heat release cannot be accurately estimated. In order to improve the running stability of the system, the daily heat removal amount of the previous day and the daily heat supplement amount of the next day are calculated as one heat supplement unit, so long as the heat supplement unit reaches the daily heat supplement amount to be supplemented, the heat supplement work of the whole heat supplement season can be considered to be realized, and when the calculation is performed in the mode, the heat supplement is not performed in the last day, and the heat supplement is required to be performed in the day after the cold season. In this calculation mode, only the working efficiency of the thermal compensator 203 at various environmental temperatures and soil temperatures needs to be known, so that the daily open time of the thermal compensator 203 can be calculated, and the heat compensation on the soil side can be realized.
First, it is necessary to know the efficiency of thermal compensation at different ambient and soil temperatures. Analysis of the historical operating data of the thermal compensator 203 is therefore required. The ambient temperature collected by the climate compensator and the soil temperature are obtained. And the daily supplementary heat of the thermal compensator 203 to the soil side, the ambient temperature of the corresponding date, the soil temperature, and the start time and the close time of the thermal compensator 203 on the corresponding date are retrieved from the database. And training a working efficiency model of the thermal compensator 203 according to the daily supplementary heat in the historical data, the starting time of the thermal compensator 203, the environmental temperature and the soil temperature of the corresponding date. At this time, the working efficiency model of the thermal compensator 203 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 203 can be obtained. Therefore, it is also necessary to acquire the temperature and the weather forecast at the time of operation of the thermal compensator 203, and acquire 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 the thermal compensator 203 in the history. Determining a first relation coefficient between the solar heat supplement quantity and the ambient temperature, the soil temperature and the starting time of the thermal compensator 203 according to the solar heat supplement quantity and the starting time of the thermal compensator 203 corresponding to the date, and the solar heat supplement quantityAnd a second coefficient of relationship to soil temperature. The calculation formula of the total heat delivered by the thermal compensator 203 is:wherein->For the on-time of the thermal compensator 203, +.>Is the off time of the thermal compensator 203. 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 203 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 the daily thermal compensator 203 is closed. Further, an efficiency curve of the thermal compensator 203 over time is obtained based on 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 203.
After obtaining the efficiency curve of the thermal compensator 203 along with time, the heat compensation amount of different time periods can be obtained according to the curve integration mode, and the starting time of the thermal compensator 203 can be further determined. The application further comprises two different implementations, in view of the cost of electricity.
The first implementation way is: when the electricity price is uniform, the electricity cost is only related to the electricity consumption time, at this time, the time of day is divided by taking the preset time interval as a reference, the heat compensation amount of the heat compensator 203 in each time interval is calculated, and finally, the starting time of the heat compensator 203 is selected as a plurality of time intervals which meet the daily heat compensation amount and have the shortest total time. Wherein the start time is the interval of the start time and the end time of the corresponding time interval. For example, the time of day may be divided at half-hour intervals, the amount of heat supplement for each half-hour of operation of the thermal compensator 203 may be calculated, and the intervals with the highest amount of heat supplement for half-hour may be selected as the activation time of the thermal compensator 203. Typically, these intervals are continuous, e.g., 12 pm to 4 pm.
The second implementation mode is as follows: when the electricity price is peak-valley electricity price, the heat compensation amount and the electricity price in each time interval need to be further calculated, and then a plurality of time intervals which satisfy daily heat compensation amount and have the lowest total electricity price amount are selected as the starting time of the thermal compensator 203 through greedy algorithm and other modes.
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 to be supplemented 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 quantity to be supplemented.
The application provides a shallow geothermal energy thermal compensation system, which adopts the following technical scheme:
referring to fig. 2 and 3, a shallow geothermal energy thermal compensation system comprises:
