Problems solved by technology

However, in order to ensure the circulation rate of the refrigerant in the refrigeration system, the operation of the compressor has a minimum operating frequency, and usually the capacity corresponding to the minimum operating frequency is greater than the capacity of the indoor unit at the minimum load, resulting in an unbalanced capacity between the outdoor unit and the indoor unit, which affects the system. The stable operation of the

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...

Abstract

The invention relates to an air-conditioning system capable of adjusting heat transfer, which includes a refrigerant circulation circuit composed of a compressor, a four-way reversing valve, an outdoor heat exchanger, an indoor heat exchanger and a gas-liquid separator. The outdoor heat exchanger It includes a plurality of refrigerant pipes arranged in regular rows and columns, and the refrigerant pipes located in different rows and columns are connected in series to form several groups of refrigerant flow paths; the refrigerant flow path is divided into the first part and the second part , the inlet ends of the refrigerant flow paths of the first part are respectively connected to the four-way reversing valve, and the outlet ends are connected to the indoor heat exchanger after being converged by the liquid distribution pipe; the refrigerant flow paths of the second part The inlet end of the pipe is connected to the output end of the liquid pipe through a throttling assembly, and the outlet end is connected to the gas-liquid separator after passing through the four-way reversing valve. The invention has reasonable design, compact structure and convenient control. By changing the working state of the outdoor heat exchanger, the heat exchange capacity of the system can be adjusted to ensure the balance of indoor and outdoor capabilities, so that the system runs stably and reliably.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system capable of adjusting indoor and outdoor heat exchange capacity, specifically an air-conditioning system capable of adjusting heat exchange capacity. Background technique [0002] At present, air conditioning systems basically include outdoor heat exchangers. In cooling operation, the outdoor heat exchanger acts as a condenser, and in heating operation, the outdoor heat exchanger acts as an evaporator. For the inverter compressor system, when the demand of the indoor unit changes, the frequency of the compressor can be automatically adjusted to adapt to the demand change. However, in order to ensure the circulation rate of the refrigerant in the refrigeration system, the operation of the compressor has a minimum operating frequency, and usually the capacity corresponding to the minimum operating frequency is greater than the capacity of the indoor unit at t...
