Embodiment 1

[0031] Such as figure 1 The 2-process parallel flow cooling and heating air conditioner shown includes compressor, compressor return air pipe, four-way valve, indoor unit, capillary assembly, upper end pipe of upper liquid collection pipe, upper liquid collection pipe, flat heat exchange pipe and lower liquid collection pipe tube, such as figure 2 As shown, the upper liquid collection pipe and the lower liquid collection pipe are in the shape of an arc curved "L" in the top view, the compressor and the compressor air return pipe are respectively connected to the two connection ports of the four-way valve, the indoor unit, the upper The first end of the liquid collection pipe is respectively connected to the other two connection ports of the four-way valve. The indoor unit is connected to the upper pipe of the upper liquid collection pipe through the capillary assembly. There is a partition inside, and the position of the partition is about 1 / 3 of the length of the upper liqu...

Embodiment 2

[0040] Such as image 3 As shown, there are two partitions inside the upper liquid collecting pipe, and one partition inside the lower liquid collecting pipe. The parallel flow heating and cooling air conditioner has 4 processes. The positions of the partitions are shown in the figure. The heat pipe is a process, the flat heat exchange tube between the upper left baffle and the lower baffle is a process, the flat heat exchange tube between the lower baffle and the upper right baffle is a process, and the one on the right side of the upper right baffle is a process. The flat heat exchange tube is a process.

[0041] The working principle of the 4-process parallel flow heating and cooling air conditioner is basically the same as that of the 2-process.

Abstract

The invention discloses a parallel flow air conditioner, comprising a compressor, a compressor muffler, a four-way valve, an indoor unit, a capillary tube assembly, a top tube of an upper fluid collection tube, an upper fluid collection tube, a flat heat exchange tube and a lower fluid collection tube, wherein a first end of the lower fluid collection tube is provided with a gas-liquid separator, the gas-liquid separator is connected with a check valve, the check valve and the first end of the upper fluid collection tube are connected with the same connector of the four-way valve in parallel. The invention also discloses a processing method of the parallel flow air conditioner. In the invention, the parallel flow technology is adopted, cooling and heating can be realized, and the problems that the flow distribution is uneven, the heat exchange efficiency is low, the volume is large and the cost is high can be solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a heating and cooling air conditioner using a parallel flow heat exchanger and a processing method thereof, which are used in household air conditioners, commercial air conditioners or other refrigeration equipment. Background technique [0002] Parallel flow heat exchangers, also known as microchannel heat exchangers, have the advantages of high heat transfer efficiency, compact structure, low noise, light weight, and low cost. It is widely used as a condenser in automobile air conditioners. In recent years, it has also been used as a condenser in household, especially commercial air conditioners. [0003] The parallel flow heat exchanger adopts flat tube enhanced heat transfer technology. It is a porous aluminum flat tube heat exchanger. Its structure is to use louver fins on the air side and small diameter multi-channel flat tubes on the refrigerant side, ...
