[0002] With the development of heat pump technology, heat pump products are gradually replacing the original fossil energy combustion heating, solving the energy conservation and emission reduction of the heating system and meeting the heating needs of various special scenarios. During heating, the temperature distribution of the enclosed space is gradient. Since the density of hot air is small, the hot air goes up, and the temperature at the high places in the enclosed space is higher than the temperature at the low places. This height is usually not a space for human activities. The heat gathers at high places and increases the heat dissipation of the enclosure structure. Therefore, how to effectively recycle and utilize the hot air at high places to reduce heating energy consumption and achieve local heating has become a technical problem that needs to be solved urgently.

[0027] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0028] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0029] Please refer to Figure 1 , is a schematic diagram of the overall structure of the mobile heating heat pump unit of the utility model, including a box body 1, and a control panel 13 is arranged on the top of the box body 1. The box body 1 is separated into an upper space and a lower space by upper and lower partitions 2. Among them, an air inlet pipe 3 is installed on the top panel of the upper space, and an air outlet pipe 4 is installed on a side panel of the upper space. In specific implementation, the air inlet pipe 3 and the air outlet pipe 4 are both made of hose materials, and the hose is easy to contact the designated position.

[0030] The upper space is equipped with a first fan 5 and a first coil 6. The upper and lower partitions are provided with a liquid sump 7 for collecting condensed water and a drain port 8 for condensed water. The first fan 5 is connected to the air inlet pipe 3 to absorb air from the top environment of the box body 1. An air inlet hole 14 is provided on one side of the lower space, and an air outlet hole 15 is provided on the other side of the lower space. The lower space is equipped with a compressor 9, a second fan 10, a second coil 11 and an electronic expansion valve. The compressor working medium is not shown in the figure. The two ends of the compressor 9 and the electronic expansion valve are respectively connected to the first coil 6 and the second coil 11 pipelines to form a pipeline circulation for the circulation of the compressor working medium. The second fan 10 absorbs air from the surrounding environment of the box body 1 from the air inlet hole 14, and the air is discharged through the air outlet hole 15 after heat exchange with the compressor working medium steam in the second coil 11.

[0031] In some embodiments, a grille louver is provided on the plate surface at the air outlet 15 , and a filter screen is provided at the air inlet 14 .

[0032] When the present embodiment realizes heating, the first fan 5 performs heat exchange between the sucked air and the compressor working medium entering the first coil 6, and the low-temperature air after heat exchange is discharged to the outside through the air outlet 4. The heat released by the air is absorbed, so that the low-temperature and low-pressure liquid working medium in the first coil 6 is vaporized, and the vaporized compressor working medium enters the compressor for compression to form high-temperature and high-pressure compressor working medium, which flows into the second coil 11. The second fan 10 absorbs air from the surrounding environment of the box body 1 through the air inlet 14. After the air exchanges heat with the compressor working medium in the second coil 11, the hot air is blown out from the air outlet 15 through the second fan 10 to heat the environment.

[0033] Of course, this embodiment can also operate in reverse to achieve a refrigeration effect. During refrigeration, the compressor 9 starts to pass the high-temperature and high-pressure working fluid gas into the first coil 6, and the first fan 5 performs heat exchange between the inhaled air and the compressor working fluid passed into the first coil 6. The high-temperature air after absorbing heat is discharged outward through the air outlet pipe 4. The high-temperature and high-pressure gas in the first coil 6 releases heat and becomes a low-temperature and high-pressure liquid. It is throttled by the electronic expansion valve to become a low-temperature and low-pressure working fluid liquid, and then passed into the second coil 11 to exchange heat with the air in the surrounding environment of the box 1, and then blows out cold air to cool the environment. At the same time, the working fluid liquid absorbs heat from the environment and vaporizes, and then passes into the compressor to cycle back and forth.

[0034] In addition, in this embodiment, a universal pulley 12 is provided at the bottom of the box body 1 to facilitate overall movement and widen its usable position.

[0035] In summary, the mobile heating heat pump unit designed by the utility model assembles the fan, compressor, coil and other components inside the box, and arranges the compressor working fluid pipeline inside the box. Compared with the traditional fixed installation method, the mobile heating heat pump unit designed by the utility model can provide heating and cooling to a local area in an open or semi-open environment. The air inlet duct is located above the unit, and its length is retractable. The heat source point can be located at a high point or a specified high temperature point, which is conducive to fully recovering the heat source in the high space of the closed environment or taking a high-temperature heat source. The air outlet is located at the bottom of the unit, and air is supplied through the grille shutters, which has the effect of floor radiation heating, and the heating area has a high degree of comfort.

[0036] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
