Embodiment Construction
[0024] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments as needed so as to adapt to specific applications. For example, although the air-conditioning unit described in this preferred embodiment has multiple indoor units, the air-conditioning unit of the present invention can obviously only include one indoor unit, and such changes in the number of indoor units do not depart from the scope of the present invention. Basic principles, therefore all will fall within the protection scope of the present invention.
[0025] It should be noted that, in the description of the preferred embodiment of the present invention, the terms "upper", "lower", "left", "right...

The invention belongs to the technical field of air conditioners, and specifically provides an air conditioning unit with defrosting branches, and aims to solve the problem that a defrosting way of anexisting air conditioning unit is not good. The air conditioning unit comprises a main circulating loop as well as an indoor coiled tube, a four-way valve, a compressor and a first outdoor coiled tube and a second outdoor coiled tube, which are arranged on the main circulating loop, wherein the first outdoor coiled tube and the second outdoor coiled tube are arranged in parallel; the first end ofthe first defrosting branch is connected to the second end of the second outdoor coiled tube; the second end of the first defrosting branch is connected between the four-way valve and the compressor,so that a high-temperature refrigerant in the compressor can directly enter the first outdoor coiled tube through the first defrosting branch; the first end of the second defrosting branch is connected to the second end of the second outdoor coiled tube, and the second end of the second defrosting branch is connected between the four-way valve and the compressor, so that the high-temperature refrigerant in the compressor directly enters the second outdoor coiled tube through the second defrosting branch. The air conditioning unit can realize alternated defrosting through multiple groups of outdoor units.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and specifically provides an air conditioning unit with a defrosting branch. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air-conditioning units have become an essential device in people's lives. Generally, an air conditioning unit includes an indoor unit, an outdoor unit, and a circulation loop for connecting the indoor unit and the outdoor unit. The refrigerant in the air conditioning unit continuously exchanges heat between the outdoor unit and the indoor unit through the circulation loop, thereby achieving the effect of changing the room temperature. . Take the heating operation of the air conditioner unit as an example, the coil of the outdoor unit is always in a low temperature state; at this...
