Embodiment 1
[0018] Such as Figure 1 As shown, an air conditioning system capable of adjusting heat transfer includes a refrigerant circulation circuit composed of a compressor 1 , a four-way reversing valve 2 , an outdoor heat exchanger 3 , an indoor heat exchanger 8 and a gas-liquid separator 9 . Wherein, the indoor heat exchanger 8 includes multiple groups connected in parallel, and each group is provided with an indoor electronic expansion valve 7 for convenient control and use. An outdoor electronic expansion valve 6 is provided between the outdoor heat exchanger 3 and the indoor heat exchanger 7 to throttle the refrigerant flowing through it.
[0019] The outdoor heat exchanger 3 includes 48 refrigerant pipes 31 arranged in sixteen rows and three columns. Six refrigerant pipes 31 in two adjacent rows are connected in series to form a group of refrigerant flow paths, and there are 7 groups in total. The connection mode of each group of refrigerant flow paths is that two refrigerant...
Embodiment 2
[0021] Such as figure 2 shown. The structure of this embodiment is basically the same as that of Embodiment 1, the main difference is that, in addition to the original 6 groups of refrigerant flow paths, the first part also includes a seventh group composed of 4 refrigerant pipes originally in the second part. Correspondingly, the second part of the refrigerant flow path in this embodiment only includes 2 refrigerant pipes, so as to meet the needs of different users.
Embodiment 3
[0023] Such as image 3 shown. The structure of this embodiment is basically the same as that of Embodiment 1, the main difference is that the throttling component in this embodiment is an electronic expansion valve 53, because it has the functions of controlling pipeline on-off and throttling at the same time, which can make the structure more Simple and easy to install and maintain.
[0024] The operating process of the present invention is:
[0025] 1. During cooling operation, the compressor absorbs the low-temperature and low-pressure gaseous refrigerant in the gas-liquid separator, and compresses it into high-temperature and high-pressure gaseous refrigerant, and then enters the first outdoor heat exchanger in multiple channels after passing through the four-way reversing valve. A part of the refrigerant flow path conducts heat exchange, cools into medium-temperature and high-pressure liquid refrigerant, and then merges into one circuit through the liquid separator, an...
