In this example, during the refrigeration process, the condensation tube group 1 has branches for the refrigerant to enter, and has branches for the refrigerant to flow out, so that the high-temperature and high-pressure gas all enters the condensation tube group 1 for condensation, the branch flow (also called path) is longer, and the heat exchange is more sufficient, thereby being beneficial to improving the condensation effect of the condenser, and also being beneficial to improving the refrigeration effect of the condenser.
In the heating process, the liquid storage area 15 is arranged at the inlet end of the refrigerant, so that the refrigerant is equally divided into the branches after passing through the liquid storage area 15, the uniformity of the division is facilitated, and the flows of the branches are close or the same, so that the compression balance is facilitated, and the heating effect of the condenser is improved.
In addition, it is understood that in the condenser provided in this embodiment, in , the intermediate tube group and/or the input tube group may further be provided with a third type of check valve, and the third type of check valve may be used to prevent the counter flow of the refrigerant, thereby facilitating the operational reliability of the condenser.
