It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Conversely, this application covers any substitutions, modifications, equivalent methods, and schemes made within the spirit and scope of this application as defined in the claims. Furthermore, to provide the public with a better understanding of this application, certain specific details are described in detail below. However, this application can be fully understood by those skilled in the art even without these detailed descriptions.

[0027] The following will combine Figure 1-2 This application provides a detailed description of an energy-consuming groundwater source heat pump system according to its embodiments. It is important to note that the following embodiments are merely illustrative and do not constitute a limitation thereof.

[0028] Please see Figure 1-2 A groundwater source heat pump system for measuring energy consumption is suitable for new construction or energy-saving renovation projects in residential buildings, schools, hospitals, hotels, supermarkets, office buildings, industrial parks, stations, airports, grain and oil storage warehouses, etc.

[0029] It includes the following four-level structure:

[0030] Level 1: Central Workstation, or control center. Composed of a PC host, monitor, and printer, it is the core of the automatic control system. All monitored groundwater source heat pump system equipment is centrally managed and the system's energy efficiency ratio is displayed here.

[0031] The central workstation is configured as follows:

[0032] Store and export historical runtime data;

[0033] The system automatically starts and stops according to a preset schedule, enabling unattended operation.

[0034] The system displays energy consumption percentage, equipment status, and fault alarm information through a visual interface.

[0035] Level 2: The controller achieves precise control of the controlled equipment through its functions such as data acquisition, processing, analysis, algorithm execution, and control command output.

[0036] The controller integrates an energy consumption monitoring module, which is used to classify and statistically analyze the power consumption of the heat pump host, circulating water pump and terminal equipment in real time, and calculate the system's comprehensive energy efficiency ratio (COP).

[0037] Level 3: Sensors and actuators, wherein the sensors are used to collect field signals and the actuators are used to execute control commands;

[0038] The sensors include temperature sensors, pressure sensors, flow sensors, and power metering instruments, and all sensor data are transmitted to the central workstation in real time via a communication module.

[0039] The actuator includes a variable frequency water pump and an electric valve. The variable frequency water pump dynamically adjusts the flow rate according to the end load demand, and the electric valve is used to automatically switch between cooling / heating modes.

[0040] Level 4: Groundwater source heat pump system, including outdoor heat exchange side, heat pump room and terminal central air conditioning equipment, used to provide energy services for buildings.

[0041] The groundwater source heat pump system, which measures energy consumption, is seamlessly integrated with an automatic control system. By setting the system's operating time, the system's on / off times can be automatically controlled, eliminating the need for on-duty personnel and achieving unattended operation. All sensors and actuators in the system utilize remote monitoring instruments and electric actuators, automatically monitoring operational data at each point and switching between cooling and heating modes based on end-customer needs. Combined with variable frequency pump technology, this enables on-demand energy supply.

[0042] All monitoring data from this system can be displayed, stored, and exported from the control center. This eliminates the need for on-site personnel to perform meter readings daily, monthly, quarterly, and yearly, significantly reducing labor costs and improving the efficiency of on-site staff. Traditional central air conditioning systems, which often lack automatic control technology and pump control technology, can only monitor specific point parameters such as temperature, pressure, and flow rate. They cannot categorize and statistically analyze the power consumption of major equipment or display the overall system's energy efficiency ratio.

[0043] Groundwater source heat pump units typically have a COP above 4, while conventional air-cooled heat pumps have a COP between 2.5 and 3.0, decreasing as outdoor temperatures drop. Groundwater source heat pumps have higher energy efficiency, producing 4 kWh of heat or cooling for every 1 kWh of electricity consumed, compared to only 2.5 to 3.0 kWh for traditional central air conditioning. When the project's energy supply area reaches a certain scale, the operating cost of this system is significantly lower than that of traditional heat pump systems, reducing overall system operating costs.

[0044] All monitoring data from this system can be displayed, stored, and exported from the control center. This eliminates the need for on-site personnel to perform meter readings daily, monthly, quarterly, and yearly, significantly reducing labor costs and improving the efficiency of on-site staff. Traditional central air conditioning systems, which often lack automatic control technology and pump control technology, can only monitor specific point parameters such as temperature, pressure, and flow rate. They cannot categorize and statistically analyze the power consumption of major equipment or display the overall system's energy efficiency ratio.

[0045] Compared to the traditional "chiller unit + gas boiler" system, the groundwater source heat pump system produces no pollutants, while the "chiller unit + gas boiler" system generates pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxides, and carbon monoxide. The groundwater source heat pump system is more environmentally friendly. It plays a crucial role in creating demonstration projects that achieve zero carbon, zero pollution, and zero emissions.

[0046] Traditional air-cooled heat pump units experience a decrease in heating capacity as ambient temperature drops. In winter, when certain temperatures and humidity levels are reached, the units shut down for defrosting, at which point they can no longer provide energy to end users. Groundwater source heat pump systems, on the other hand, are highly efficient heat pump technologies that utilize the constant temperature characteristics of groundwater for heating and cooling. They extract heat or cold from groundwater to provide heating or cooling services to buildings, while simultaneously releasing the heat or cold back into the groundwater, achieving a cycle of energy transfer. This system offers a more stable and safer energy supply than traditional air-cooled heat pump units.

[0047] This application also provides an energy consumption monitoring method, including the following steps:

[0048] Real-time operating parameters of the heat pump unit, water pump, and terminal equipment are collected through sensors.

[0049] Categorize and statistically analyze the energy consumption data of each device, and calculate the overall energy efficiency ratio of the system;

[0050] Optimize control strategies based on energy consumption data to achieve on-demand energy supply.

[0051] Further, it includes using machine learning algorithms to analyze historical data, predict future load demand, and adjust system operating parameters in advance.

[0052] The beneficial effects that a groundwater source heat pump system for measuring energy consumption disclosed in this application may bring include, but are not limited to:

[0053] This system employs computer technology, automatic monitoring technology, communication technology, and automatic control technology to automatically monitor and control the outdoor heat exchange side, ground source heat pump unit, circulating water pump, and air conditioning terminal equipment within the building of the groundwater source heat pump system, providing power on demand. In addition to collecting first-hand operational data, the system also includes a classification and statistical system for energy consumption monitoring instruments and meters, focusing on the power consumption of key equipment, and calculates the comprehensive energy efficiency ratio of the groundwater source heat pump system. This allows users to gain a clearer understanding of the system's actual energy-saving effects.
