Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, and more specifically, to a water source heat pump unit. Background Technology

[0002] With the increasing demands for energy conservation and emission reduction and the vigorous promotion of renewable energy utilization, water source heat pump technology, as a mature and efficient means of utilizing shallow geothermal energy for building heating and cooling, has been widely used in the construction field. Its working principle is mainly to drive the refrigerant circulation by inputting a small amount of high-grade electrical energy, and to realize the transfer of energy from a low temperature to a high temperature by utilizing the relatively constant temperature characteristics of water, thereby achieving the purpose of heating or cooling the building. Compared with traditional air source heat pumps and coal / gas boiler systems, water source heat pumps have significant advantages such as high energy efficiency ratio, stable operation, and environmental friendliness. However, existing water source heat pump units have insufficient adaptability to water quality and are inconvenient to maintain.

[0003] On the one hand, the ideal water source should be a clean water body with few impurities. However, in actual engineering projects, water sources such as groundwater often contain varying degrees of impurities such as silt and suspended solids. These impurities can easily cause deposits and scale to form on the heat pump unit over a long period of time, affecting the heat exchange efficiency between the heat pump unit and the water source.

[0004] On the other hand, in order to save above-ground space or meet specific installation requirements, water source heat pump units are often deployed in relatively enclosed, hidden areas such as underground machine rooms and equipment mezzanines, where personnel are not easily able to frequently reach. Although this solves the space problem, it brings great inconvenience to the monitoring and maintenance of the equipment.

[0005] Therefore, existing heat pump units need improvement in terms of water quality adaptability and equipment maintenance. Utility Model Content

[0006] In view of the aforementioned problems, and in conjunction with the first aspect of this utility model, an embodiment of this utility model provides a water source heat pump unit, achieved by the following specific technical means:

[0007] A water source heat pump unit includes a base and a heat pump unit body. The heat pump unit body is mounted on the top of the base. A water outlet pipe is mounted on the top of the heat pump unit body. A settling tank is mounted on one side of the heat pump unit. A water inlet pipe and a connecting pipe are mounted on both sides of the settling tank. A sludge collection pipe and a valve are mounted at the bottom of the settling tank. A sludge collection box is also mounted at the bottom of the settling tank. A filter plate is mounted inside the settling tank. A cleaning frame is mounted on one side of the sludge collection box.

[0008] A thermistor is installed inside the water outlet, a temperature sensor is installed inside the sedimentation tank, a leakage sensor is installed on the top of the sludge collection tank, and a signal transmission module is installed on the top of the base.

[0009] According to a preferred embodiment, the base is provided with a mounting platform on top, the heat pump unit body is mounted on the top of the mounting platform, the water outlet pipe is welded to the top of the heat pump unit body, and the thermistor is fixedly connected inside the water outlet pipe.

[0010] According to a preferred embodiment, the bottom of the sludge collection box is fixedly connected to the base, the cleaning frame is attached to one side of the sludge collection box, a handle is provided on one side of the cleaning frame, a connection port is provided on the top of the sludge collection box, and the leakage sensor is fixedly connected to the top of the sludge collection box.

[0011] According to a preferred embodiment, the sedimentation tank is welded to the bottom of the sludge collection pipe, the bottom of the sludge collection pipe is connected to the connection port, and a rotating valve is provided on one side of the sludge collection pipe.

[0012] According to a preferred embodiment, a clamp is provided inside the settling tank, and the filter plate is clamped on the top of the clamp. Two sets of fixing members are also provided inside the settling tank, and the temperature sensor is clamped on one side of each of the two sets of fixing members. The temperature sensor is located above the filter plate.

[0013] According to a preferred embodiment, the connecting pipe and the water inlet pipe are located above and below the filter plate, respectively, and one end of the connecting pipe is connected to the heat pump unit body.

[0014] The top of the settling tank is bolted to a sealing cap.

[0015] According to a preferred embodiment, the base is detachably connected to a mounting seat on its top, the mounting seat contains the signal transmission module, the mounting seat has a cover plate on its top, and a sealing ring is provided at the bottom of the cover plate.

[0016] According to a preferred embodiment, the thermistor, temperature sensor, and leakage sensor are all electrically connected to the signal transmission module.

[0017] Based on the above aspects, this utility model has the following beneficial effects:

[0018] First, the water source enters the settling tank through the inlet pipe near the bottom. The settling tank is equipped with a filter plate to filter out impurities such as mud and sand from the water source, causing these impurities to accumulate at the bottom of the settling tank. Finally, they are deposited into the cleaning frame inside the sludge collection box through the sludge collection pipe. Users can close the sludge collection pipe by turning the valve on the sludge collection pipe, then remove the bolts around the cleaning frame and pull it out to clean the deposited mud and sand. This prevents the mud and sand from entering the heat pump unit and forming deposits that would affect the heat exchange efficiency between the heat pump unit and the water source, thus improving the service life and heat exchange efficiency of the heat pump unit.

[0019] Secondly, the temperature of the water source before it flows through the heat pump unit is monitored by a temperature sensor inside the settling tank, and the temperature of the water source after it flows through the heat pump unit is monitored by a thermistor inside the outlet pipe. The two sets of temperature data are sent to the user's remote terminal through a signal transmission module. The user can monitor whether the heat pump unit is working properly. If the temperature difference before and after the water source flows through the heat pump unit decreases, it indicates that the heat pump unit has malfunctioned, and the user can go there for maintenance in time. The leakage sensor can monitor whether the water source heat pump unit is leaking. If a leakage occurs, the leakage sensor detects the leakage and sends an electrical signal to the signal transmission module, which then sends a signal to the user's remote terminal. The user can then shut off the water supply and have the water source heat pump unit maintained in time. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings. Figure 1 This is a structural schematic diagram of a water source heat pump unit provided in an embodiment of this utility model. Figure 2 This is an exploded view of a water source heat pump unit provided in an embodiment of this utility model. Figure 3This is a schematic diagram of the structure of a settling tank in a water source heat pump unit provided by an embodiment of this utility model. Figure 4 yes Figure 3 The enlarged view of region a is shown below. The following is a detailed introduction to this type of water source heat pump unit.

[0027] A water source heat pump unit comprises a base 100 and a heat pump unit body 101. The base 100 provides stable support for the entire unit, and its top supports the heat pump unit body 101, which is the core component for heat exchange. Its top is equipped with a water outlet pipe 102 for discharging water after heat exchange. A settling tank 103 is mounted on one side of the heat pump unit body 101. An inlet pipe 104 and a connecting pipe 105 are respectively connected to the two sides of the settling tank 103. The inlet pipe 104 is used to introduce water, and the connecting pipe 105... The settled water is transported to the heat pump unit body 101. A sludge collection pipe 106 is installed at the bottom of the settling tank 103. A rotary valve 107 is installed on the sludge collection pipe 106. The bottom of the settling tank 103 is also connected to a sludge collection box 108, which is used to collect the impurities that settle from the settling tank 103. A filter plate 109 is installed inside the settling tank 103 to perform preliminary filtration on the incoming water and to collect impurities at the bottom of the settling tank 103, so that the impurities can settle. A cleaning frame 110 is provided on one side of the sludge collection box 108 to facilitate the cleaning of the collected impurities.

[0028] A thermistor 111 is installed inside the outlet pipe 102, a temperature sensor 112 is installed inside the settling tank 103, and a signal transmission module 114 is installed on the top of the base 100. The function of this module is to transmit the electrical signals generated by the thermistor 111, the temperature sensor 112 and the leakage sensor 113 to the user's remote terminal so that the user can understand the operating status of the unit in a timely manner.

[0029] A mounting platform 115 is set on the top of the base 100. The heat pump unit body 101 is firmly installed on the top of the mounting platform 115. The water outlet pipe 102 is fixed to the top of the heat pump unit body 101 by welding to ensure the connection is firm. A thermistor 111 is fixedly connected inside the water outlet pipe 102 to monitor the temperature of the water after heat exchange through the heat pump unit body 101, providing a basis for users to judge the operating effect of the unit.

[0030] The bottom of the sludge collection tank 108 is fixedly connected to the base 100 to ensure that it will not move arbitrarily during use. A cleaning frame 110 is provided on one side of the sludge collection tank 108, and a handle 120 is installed on one side of the cleaning frame 110 for easy pulling out by the user. A connection port 121 is provided on the top of the sludge collection tank 108 for connecting to the sludge collection pipe 106. A leak sensor 113 is also fixedly connected to the top to monitor whether there is any liquid leakage in the sludge collection tank 108 in real time. Once a leak occurs, the leak sensor 113 will detect it and send an electrical signal to the signal transmission module 114. After receiving the signal, the signal transmission module 114 will send a signal to the user's remote terminal so that the user can shut off the water supply in time and perform maintenance on the water source heat pump unit to avoid greater losses due to leakage.

[0031] A sludge collection pipe 106 is welded to the bottom of the settling tank 103. The bottom of the sludge collection pipe 106 is connected to the connection port 121 at the top of the sludge collection box 108. A rotary valve 107 is installed on one side of the sludge collection pipe 106. Users can control the opening and closing of the sludge collection pipe 106 by operating the rotary valve 107, which facilitates the cleaning of impurities in the settling tank 103 and the sludge collection box 108.

[0032] The settling tank 103 is equipped with a clamp 122, and the filter plate 109 is clamped on the top of the clamp 122 to fix the filter plate 109. The settling tank 103 is also equipped with two sets of fixing parts 123. The temperature sensor 112 is clamped on one side of the two sets of fixing parts 123 and is located above the filter plate 109. This can accurately monitor the temperature of the water source after preliminary filtration. The temperature data of the water source before flowing through the heat pump unit body 101 is sent to the user's remote terminal through the signal transmission module 114. The user can judge whether the heat pump unit body 101 is working properly based on the temperature change before and after. If the temperature difference of the water source before and after flowing through the heat pump unit body 101 decreases, it means that the heat pump unit body 101 may be malfunctioning, and the user can go for maintenance in time.

[0033] Connecting pipe 105 and inlet pipe 104 are located above and below filter plate 109, respectively. One end of connecting pipe 105 is connected to the heat pump unit body 101. Water first enters settling tank 103 through inlet pipe 104 near the bottom of settling tank 103. In settling tank 103, filter plate 109 filters out impurities such as mud and sand from the water source, causing the impurities to accumulate at the bottom of settling tank 103. Finally, they are deposited into the cleaning frame in sludge collection box 108 through sludge collection pipe 106. In section 110, when it is necessary to clean impurities, the user first closes the rotary valve 107 on the sludge collection pipe 106, then removes the bolts around the cleaning frame 110, pulls out the cleaning frame 110, and cleans the deposited mud and other impurities. This design can effectively prevent mud and other impurities from entering the heat pump unit body 101 and forming deposited dirt, avoiding affecting the heat exchange efficiency between the heat pump unit body 101 and the water source, thereby improving the service life of the heat pump unit and enhancing its heat exchange efficiency.

[0034] The top of the settling tank 103 is connected to a sealing cover 116 by bolts. The sealing cover 116 can prevent water from splashing out of the settling tank 103 and prevent external debris from entering the settling tank 103, thus ensuring the normal operation of the filtration process inside the settling tank 103.

[0035] The mounting base 117 is installed on the top of the base 100 in a detachable manner. The signal transmission module 114 is placed inside the mounting base 117, which facilitates the installation, maintenance and replacement of the signal transmission module 114. The top of the mounting base 117 is provided with a cover plate 118, and a sealing ring 119 is installed at the bottom of the cover plate 118. The sealing ring 119 can enhance the sealing between the cover plate 118 and the mounting base 117, and prevent external dust, moisture and other substances from entering the mounting base 117 and affecting the normal operation of the signal transmission module 114.

[0036] Thermistor 111, temperature sensor 112 and leakage sensor 113 are all electrically connected to signal transmission module 114.
