Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a detection unit and a heat pump including the same. Background Art

[0002] A heat pump is a highly energy-efficient device that makes full use of low-grade heat energy. Generally speaking, heat can spontaneously transfer from a high-temperature object to a low-temperature object, but it cannot spontaneously go in the opposite direction. However, the working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It only consumes a small amount of net work in the reverse cycle and can obtain a large amount of heat supply, effectively utilizing the difficult-to-apply low-grade heat energy to achieve the purpose of energy conservation.

[0003] The heat pump main unit is generally set outdoors. In order to make full use of low-grade heat energy, existing heat pumps all have large-area evaporators. Since the evaporator occupies most of the space position of the heat pump, the configuration of its internal components is very compact.

[0004] Since the heat pump is very sensitive to data of the external environment, the heat pump needs to rely on environmental probes to detect data of the external environment, providing data reference for the operating parameters of the heat pump, so as to better adjust the operating parameters of the heat pump, thereby achieving a balance between energy conservation and power consumption. In order to enable the environmental probe to better detect data of the external environment, generally the environmental probe is set in the air duct of the evaporator. However, since the evaporator occupies most of the space position of the heat pump, in the prior art, the environmental probe can only be set close to the evaporator.

[0005] Since the environmental probe is close to the evaporator, the heat transfer of the fins on the evaporator has a great influence on the environmental probe, and temperature compensation needs to be introduced during design. However, no matter how temperature compensation is carried out, the data detected by the environmental probe can never be compared with the actual data, resulting in the operating parameters of the heat pump never being able to match the actual situation, which will affect the actual use effect of the heat pump. Content of the Utility Model

If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0031] In the description of the present utility model, unless otherwise clearly defined, words such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present utility model in combination with the specific content of the technical solution.

[0032] As Figures 1 to 3 shown, the detection unit according to the first aspect embodiment of the present utility model includes an outer skeleton 100, an evaporator 200, and an environmental probe 300, wherein the outer skeleton 100 is the housing of a heat pump, and components such as the evaporator 200, compressor 500, and heat exchanger 600 in the heat pump are all installed inside the outer skeleton 100. Since the evaporator 200 needs to be in contact with the external environment to exchange heat with the heat exchanger 600 using the low-grade heat energy in the external environment, the outer skeleton 100 is provided with a number of open surfaces 110, and the open surfaces 110 correspond to the vertical surfaces 210 of the evaporator 200. That is to say, the vertical surfaces 210 of the evaporator 200 can be in direct contact with the external environment through the open surfaces 110, and the evaporator 200 is spaced from the outer skeleton 100, so that a air duct 101 is reserved between the outer skeleton 100 and the evaporator 200, and external air enters the air duct 101 through the open surfaces 110 on the outer skeleton 100, and the air in the air duct 101 is in full contact with the evaporator 200.

[0033] Since the housing of the heat pump is a frame structure, the outer skeleton 100 has a bottom surface, a top surface, and a number of columns 120 connected between the bottom surface and the top surface. The shape of the outer skeleton 100 is determined according to the internal layout of the heat pump. Generally, the outer skeleton 100 is in a three-dimensional rectangular structure, and in special cases, it can be in a three-dimensional triangular prism structure or a three-dimensional polygonal prism structure. In this embodiment, the outer skeleton 100 is in a three-dimensional rectangular structure, and the shape of the evaporator 200 is generally a three-dimensional rectangle, which has a bottom surface, a top surface, and four vertical surfaces 210. In order to facilitate the processing of the turning positions of the evaporator 200, an arc-shaped corner 220 is processed between every two vertical surfaces 210 by a bending process, that is, the evaporator 200 has four arc-shaped corners 220.

[0034] Correspondingly, at least one of the upright columns 120 is located at the arc-shaped corner 220 of the evaporator 200. In this embodiment, there are two upright columns 120 of the outer frame 100 respectively located at the arc-shaped corners 220 of the evaporator 200. For the convenience of the following description, the upright column 120 located at the arc-shaped corner 220 of the evaporator 200 in the present utility model is defined as the first upright column, and the remaining upright columns 120 are defined as the second upright columns.

[0035] Since the environmental probe 300 is detected through a metal part, and the upright column 120 is also a metal component, in order to avoid the environmental probe 300 from coming into contact with the first upright column, an installation plate 400 is connected to the inner side of one of the first upright columns. The installation plate 400 can be selected as a plastic part, and the environmental probe 300 is connected to the installation plate 400. At this time, the environmental probe 300 is located between the evaporator 200 and the first upright column and is located in the air duct 101 to detect the environmental data in the air duct 101. The environmental probe 300 does not extend to the open surface 110 to hide the environmental probe 300 in the first upright column to prevent it from accelerating aging due to sun and rain.

[0036] In some embodiments of the present utility model, the number of the environmental probes 300 is one, which is close to the front of the evaporator 200 to better detect the environmental data in the air duct 101. However, in some other embodiments, the number of the environmental probes 300 can also be multiple, and the multiple environmental probes 300 are respectively in different first upright columns, not limited to the above embodiments.

[0037] With the above structure, since the environmental probe 300 is farther away from the evaporator 200 compared with the prior art, the environmental probe 300 is less affected by the evaporator 200, and the detection result is more accurate. Moreover, since the environmental probe 300 is arranged at the arc-shaped corner 220 of the evaporator 200, there is no need to reserve an additional space position for the installation of the environmental probe 300, so as to make full use of the space inside the heat pump, and the first upright column can provide protection for the environmental probe 300 to hide the environmental probe 300, thereby effectively extending the service life of the environmental probe 300.

[0038] Such as Figure 1As shown in the figure, the heat pump according to the second aspect embodiment of the present utility model includes a detection unit according to the first aspect embodiment of the present utility model above, and further includes a compressor 500 and a heat exchanger 600. Both the compressor 500 and the heat exchanger 600 are installed within the outer frame 100. The compressor 500, the heat exchanger 600, and the evaporator 200 are connected through pipelines. Since the compressor 500 and the heat exchanger 600 occupy part of the spatial position of the heat pump, the second upright column of the outer frame 100 corresponds to the compressor 500 and the heat exchanger 600, rather than corresponding to the arc-shaped corner 220 of the evaporator 200. To improve the heat exchange efficiency of the evaporator 200, the evaporator 200 is provided with a plurality of fins.

[0039] During operation, the compressor 500 in the heat pump compresses the normal-temperature and low-pressure gaseous refrigerant entering from the refrigerant inlet into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows out from the refrigerant outlet. When the high-temperature and high-pressure gaseous refrigerant flows through the heat exchanger 600, it liquefies and releases heat to become a normal-temperature and high-pressure liquid refrigerant. The heat exchanger 600 transfers the heat generated during the liquefaction and heat release of the refrigerant to the heat-receiving facility. After the normal-temperature and high-pressure liquid refrigerant passes through the liquid storage tank and the filter, it starts to enter the expansion valve. Since the expansion valve can change the throttling section or the throttling length to control the flow rate of the refrigerant, the normal-temperature and high-pressure liquid refrigerant becomes a low-temperature and low-pressure liquid refrigerant after flowing through the expansion valve. The low-temperature and low-pressure liquid refrigerant absorbs the low-grade heat of the ambient air and evaporates when flowing through the evaporator 200. After the action of the evaporator 200, the low-temperature and low-pressure liquid refrigerant becomes a normal-temperature and low-pressure gaseous refrigerant. The water vapor in the air condenses into water droplets on the water collection plate and flows into the water collection box. A small part of the liquid refrigerant that is not fully vaporized is recovered by the gas-liquid separator into the liquid storage tank. The normal-temperature and low-pressure gaseous refrigerant then enters the compressor 500 from the refrigerant inlet and repeats the above process again.

[0040] Since the environmental probe 300 of the present utility model can more accurately detect environmental data, the operating parameters of the heat pump can be matched to the actual situation to improve the efficiency of the heat pump.

[0041] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present utility model.
