[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention; however, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details; in other examples, some technical features known in the art are not described to avoid confusion with the present invention, and it should be understood that the present invention may be practiced in different forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0056] The terminology used herein is intended only to describe specific embodiments and is not intended to limit the present invention. When used herein, the singular forms "a," "an," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "comprising" and / or "including," when used in this specification, identify the presence of the recited features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups. When used herein, the term "and / or" includes any and all combinations of the relevant listed items.

[0057] In order to thoroughly understand the present invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present invention; optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementation methods.

[0058] like Figure 1 As shown, in one embodiment, a temperature-based energy recovery device is provided, comprising:

[0059] Geothermal heat pumps, which use shallow geothermal heat to output a heat transfer fluid with adjustable temperature;

[0060] A temperature monitor is connected to the output end of the ground source heat pump and is used to detect the temperature of the heat transfer fluid in real time;

[0061] A fluid distribution unit having an input end and three output ends, wherein the input end is connected to the output end of the ground source heat pump and is used to determine the three output ends according to a comparison relationship between the temperature of the heat transfer fluid and a preset temperature threshold;

[0062] a heat recovery assembly, comprising a first heat exchanger and a first heat storage container, connected to the first output end of the fluid distribution unit;

[0063] a cold recovery assembly, comprising a second heat exchanger and a second cold storage container, connected to the third output end of the fluid distribution unit;

[0064] The main water pipe is connected to the second output end of the fluid distribution unit.

[0065] This energy recovery device first extracts energy from the ground surface using a ground-source heat pump and outputs it through a heat transfer fluid, which itself forms the basis for converting low-grade thermal energy into usable energy. The core of the device lies in its intelligent control capabilities: a temperature monitor obtains real-time temperature information from the heat transfer fluid, providing a basis for subsequent energy allocation decisions. Next, a fluid distribution unit acts as a "smart valve" based on the comparison of the real-time temperature with a preset threshold. When the fluid temperature is high, the distribution unit directs it to the heat recovery component. Here, the high-temperature fluid passes through the first heat exchanger, transferring excess heat to the first heat storage container for storage, avoiding direct loss or inefficient use of the high-temperature heat energy and achieving heat recovery and storage. Conversely, when the fluid temperature is low, the distribution unit directs it to the cold recovery component. The low-temperature fluid passes through the second heat exchanger, transferring the cold energy to the second cold storage container for storage, effectively recovering the low-temperature cold energy and preventing it from being wasted.

[0066] Furthermore, when the temperature of the heat transfer fluid is in a mild state between preset thresholds, the fluid is directed to the water main, where it may be used to directly meet part of the building's temperature control needs (such as heating or water supply), or enter the next processing link, which reflects the direct utilization of medium-temperature energy.

[0067] This refined energy management based on temperature gradient minimizes the large-scale loss of energy or grade mismatch in a single link, significantly improves the overall utilization efficiency of energy extracted from the surface layer, and achieves more optimized energy recovery and utilization.

[0068] In some embodiments, the fluid dispensing unit comprises:

[0069] Drive motor, used to adjust the opening of the valve;

[0070] Flow sensors are provided at the input end and the three output ends.

[0071] After integrating the drive motor and flow sensor into the device, the fluid distribution unit can achieve precise flow control and dynamic adjustment of the heat transfer fluid: the drive motor can accurately control the flow ratio of the fluid flowing to each output end according to the temperature threshold comparison result by adjusting the valve opening in real time, avoiding the energy waste caused by the extensive on-off control of traditional mechanical valves; the flow sensors are respectively set at the input end and the three output ends, which can monitor the fluid flow data of each pipeline in real time and feed it back to the control system, forming a closed-loop control mechanism of "temperature detection-flow regulation-data feedback". This design not only ensures that the heat recovery component and the cold recovery component obtain matching fluid flow in different temperature ranges, improving the heat exchange efficiency (such as high-temperature fluid entering the heat recovery component at a larger flow rate to maximize heat storage), but also optimizes the rationality of the preset temperature threshold through flow data to avoid energy recovery failure due to abnormal flow.

[0072] In some embodiments, the heat recovery assembly comprises:

[0073] a phase change material layer disposed in the first heat storage container;

[0074] a temperature stratification structure disposed between the phase change material layer and the first heat storage container, for maintaining a temperature gradient of the first heat storage container.

[0075] The addition of the phase change material layer and the temperature stratification structure in the heat recovery assembly can significantly improve the heat storage efficiency and energy utilization accuracy: the phase change material layer utilizes the characteristics of absorbing / releasing latent heat during the phase change process, and compared with the traditional sensible heat storage method, has higher heat storage density per unit volume, can store more heat in a smaller space, and at the same time, the temperature fluctuation during the phase change process is small, which can maintain the relative stability of the temperature in the heat storage container.

[0076] The temperature stratification structure is disposed between the phase change material layer and the heat storage container, and by blocking heat convection and heat conduction, a temperature gradient distribution of hot at the top and cold at the bottom is formed in the container. This structure can not only prevent the mixing of heat in the high-temperature region and the low-temperature region, and ensure the on-demand distribution of heat energy in different temperature ranges (such as the storage of high-temperature fluid in the upper layer of the container), but also can accurately control the temperature boundary during the heat exchange process, and reduce heat loss. The combination of the two makes the heat recovery assembly not only store heat efficiently through the phase change material when receiving high-temperature heat transfer fluid, but also maintain the temperature gradient of the heat storage container through the temperature stratification structure, so that when the system needs to supply heat, heat can be extracted from the corresponding temperature range according to the demand, improving the specificity of heat energy utilization and the economy of system operation, and is especially suitable for heat supply scenarios with high temperature stability requirements.

[0077] In some embodiments, the cold recovery assembly comprises:

[0078] a thermal insulation material for maintaining a set temperature of the second cold storage container;

[0079] a frost prevention device disposed on the surface of the second heat exchanger.

[0080] The addition of the thermal insulation material and the frost prevention device in the cold recovery assembly can effectively improve the cold storage efficiency and the reliability of system operation: the thermal insulation material is wrapped outside the second cold storage container, which reduces the heat exchange rate between the container and the external environment, reduces the loss of cold during storage, and ensures that the temperature in the cold storage container is maintained at a set threshold (such as 15°C), avoiding the decrease of secondary utilization efficiency caused by the attenuation of cold; the frost prevention device is disposed on the surface of the second heat exchanger, which prevents the surface temperature of the heat exchanger from being lower than the dew point temperature during the heat exchange process of the low-temperature heat transfer fluid, thereby preventing frost from forming, avoiding the decrease of heat exchange area and the increase of thermal resistance caused by the attachment of frost, and maintaining the stability of heat exchange efficiency.

[0081] In some embodiments, the first heat storage container and the second cold storage container are respectively provided with a temperature sensor and a liquid level sensor, and the temperature sensor and the liquid level sensor are connected to the fluid distribution unit. When the signals collected by the temperature sensor and the liquid level sensor are within an abnormal range, the temperature sensor and the liquid level sensor issue an alarm, and the fluid distribution unit suspends fluid distribution.

[0082] On the one hand, the abnormal temperature alarm can avoid the decline in system efficiency caused by heat exchange failure or energy leakage of heat storage / cold storage containers (for example, when the temperature of the cold storage container rises abnormally, cold recovery is suspended to prevent waste of cold); on the other hand, abnormal liquid level monitoring can prevent the continued input of fluid when the medium in the container is insufficient, resulting in empty tank operation and avoiding equipment damage. In addition, the linkage control of the sensor and the fluid distribution unit forms a closed-loop feedback system. When the temperature or liquid level returns to normal, the fluid distribution unit can automatically resume work to achieve adaptive adjustment of the system. This mechanism effectively solves the safety hazard problem caused by the lack of real-time status monitoring in traditional energy recovery systems. It not only ensures the safe operation of the equipment, but also maintains the stability of energy recovery efficiency through dynamic regulation.

[0083] In some embodiments, the preset temperature thresholds include: a heat recovery threshold and a cold recovery threshold;

[0084] When the temperature of the heat transfer fluid is greater than the heat recovery threshold, controlling the heat transfer fluid to flow out from the first output end;

[0085] When the temperature of the heat transfer fluid is less than or equal to the heat recovery threshold and greater than the cold recovery threshold, controlling the heat transfer fluid to flow out from the second output end;

[0086] When the temperature of the heat transfer fluid is less than or equal to the cold recovery threshold, the heat transfer fluid is controlled to flow out from the third output end.

[0087] The temperature range is divided into three levels through dual thresholds, so that the heat recovery component, main water pipe, and cold recovery component correspond to the processing paths of high-temperature, medium-temperature, and low-temperature fluids respectively, avoiding the energy recovery blind spot caused by traditional single-threshold control and improving energy utilization.

[0088] Preferably, the heat recovery threshold is the average temperature of the heat storage container, and the cold recovery threshold is a fixed value, and the specific value can be manually adjusted according to different application scenarios.

[0089] The present invention also proposes a temperature-based energy recovery method, comprising the following steps:

[0090] S101, using a ground source heat pump to output a temperature-adjustable heat transfer fluid using shallow geothermal heat;

[0091] S102, obtaining the current temperature of the heat transfer fluid;

[0092] S103, comparing the current temperature with a preset heat recovery threshold and a cold recovery threshold;

[0093] S104: If the current temperature is greater than the heat recovery threshold, control the heat transfer fluid to flow to the heat recovery component for heat recovery;

[0094] S105: If the current temperature is less than or equal to the heat recovery threshold and greater than the cold recovery threshold, control the heat transfer fluid to flow to the main water pipe;

[0095] S106: If the current temperature is less than or equal to the cold recovery threshold, control the heat transfer fluid to flow to the cold recovery component to recover cold energy.

[0096] In some embodiments, the heat recovery threshold and the cold recovery threshold are adjusted according to local climate conditions, indoor air conditioning set temperature, and operating characteristics of the ground source heat pump.

[0097] The present invention further provides a readable storage medium storing a computer program. When the computer program is executed by a processor, the processor performs the following steps:

[0098] A ground source heat pump utilizes shallow geothermal heat to output a temperature-adjustable heat transfer fluid;

[0099] Get the current temperature of the heat transfer fluid;

[0100] Comparing the current temperature with preset heat recovery thresholds and cold recovery thresholds;

[0101] If the current temperature is greater than the heat recovery threshold, the heat transfer fluid is controlled to flow to the heat recovery component for heat recovery;

[0102] If the current temperature is less than or equal to the heat recovery threshold and greater than the cold recovery threshold, the heat transfer fluid is controlled to flow to the main water pipe;

[0103] If the current temperature is less than or equal to the cold recovery threshold, the heat transfer fluid is controlled to flow to the cold recovery component to recover cold energy.

[0108] If the current temperature is greater than the heat recovery threshold, the heat transfer fluid is controlled to flow to the heat recovery component for heat recovery;

[0109] If the current temperature is less than or equal to the heat recovery threshold and greater than the cold recovery threshold, the heat transfer fluid is controlled to flow to the main water pipe;

[0110] If the current temperature is less than or equal to the cold recovery threshold, the heat transfer fluid is controlled to flow to the cold recovery component to recover cold energy.
