Problems solved by technology

[0002] At present, the common problems in the air source heat pump industry are: 1. The heat exchanger of the outdoor unit is extremely unreasonable, the efficiency is low, and the energy consumption of frosting and defrosting is large
2. When the outdoor unit is defrosting in winter, the condensed water dripping often brings troubles to passers-by, and the icicles formed by the defrosting of outdoor units installed in high-rise buildings will bring safety hazards to passers-by below.
3. When cooling in summer, the indoor heat exchange condensate is directly discharged to the outside, which often brings embarrassment to passers-by, and there is no perfect technical solution to make carbon dioxide efficient refrigeration technology path
4. At present, for small central air conditioners with floor heating metal capillary tubes, when installing the outdoor unit, it is necessary to drill holes in the upper part of the outer wall of the building to pass indoor on-hook pipelines, and to drill holes in the lower part to pass floor heating metal capillary tubes. The construction cost is high and it is not conducive to building structure safety
5. The original design of the existing household air conditioner outdoor unit is mainly to facilitate the installation of windows and instantaneous heat removal. There is no maximum external surface heat exchanger per unit volume specially designed for continuous heating, so as to achieve low temperature difference in winter, high-efficiency heat exchange and less frosting. Low temperature differential carbon dioxide refrigerant circulation for multiple heat removal purposes
6. The noise of the current household heat pump cooling and heating outdoor units is generally 52-58db.
7. The existing upper exhaust air conditioner is not designed according to the conclusion of the cylindrical wind tunnel experiment, that is, the wind force at the center of the fan circle is weak, the angular velocity of the fan edge is high, and the air volume is large. The optimal design of the whole machine is carried out.
9. When connecting to the soil source interface, it is easy to cause condensation on the indoor ground

Embodiment 1

[0041] combine figure 1 , figure 2 , image 3 The working principle of the present invention is further described:

[0042] In this embodiment, the outdoor heat exchanger 5 adopts a ring structure, which can be a ring shape or a regular polygon, and a baffle 34 is provided at the gap of the ring structure; In the central area of ​​the heat exchanger 5, there is a heat exchange air duct between the heat exchanger shell 23 and the lining fiber 7 and the outdoor heat exchanger 5; An external machine installation handle 29 is provided, and the ratio of the transverse length of the notch of the annular structure to the total circumference of the annular structure cross section is: I: L=1:1 / 20~1 / 4; where: I is the ring L is the transverse length of the notch of the annular structure; L is the total perimeter of the cross-section of the annular structure; the outdoor heat exchanger 5 is provided with a coating for absorbing sunlight and heat.

Embodiment 2

[0058] combine Figure 4 The sectional structure diagram of the unit with cascaded fans and soil source interface further discusses the working principle.

[0059] and figure 1 figure 2 image 3 Compared with Embodiment 1, an annular cascaded fan 31 is provided at the lower part of the outdoor heat exchanger 5 , and its power is generally smaller than that of the outdoor exhaust fan 18 . The throttling component 9 passes through a switching interface and a pipe connection valve 33 for the soil source heat exchange fluid. The upper port of the outdoor heat exchanger 5 is connected to the soil source heat exchange gas pipe connection valve 32 through a branch manifold, and other various parts are connected with the valve 32. figure 1 figure 2 image 3 same. It is also suitable for making larger size and higher power products, especially suitable for villas, small offices and other places.

Embodiment 3

[0063] Figure 5 It is a structural diagram of the outdoor machine of the present invention to condense water, dissipate heat, dissipate heat and exchange air. Among them: the features corresponding to the labels 1-29 are the same as figure 1 figure 2 image 3 The same, except that the external heat exchanger and the casing are of traditional structure. The purpose of this design is to use many molds in the external unit of the air conditioner in the existing factory, which greatly reduces the cost. Refrigerants bring huge environmental benefits. The working principle is the same as that of Embodiment 1, and will not be repeated here.
