Abstract

The invention discloses a heat exchanger, a heat exchanger flow path control method, a readable storage medium and a household appliance. The heat exchanger comprises an inflow pipe, an outflow pipe, a first heat exchange pipe set, a second heat exchange pipe set, a first electromagnetic valve and a switching valve set. One end of the first heat exchange pipe group communicates with the inflow pipe through a first pipeline; the other end of the second heat exchange pipe group is communicated with the outflow pipe through a third pipeline; the first electromagnetic valve is arranged on the second pipeline; the first end of the switching valve set communicates with the outflow pipe, the second end communicates with the end, away from the inflow pipe, of the first heat exchange pipe set, and the third end communicates with the end, close to the first electromagnetic valve, of the second heat exchange pipe set. According to the technical scheme, different numbers of heat exchange flow paths can be switched between different load changes.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a heat exchanger, a method for controlling a flow path of the heat exchanger, a readable storage medium, and a household appliance applying the heat exchanger. Background technique [0002] The optimal flow paths of indoor and outdoor heat exchangers are different for air conditioners or water heaters at different operating frequencies. When operating under small load or low frequency, the pressure loss is small, then we need to use less shunts to increase the flow rate of refrigerant and increase the heat transfer coefficient; when operating under heavy load or medium and high frequency, the same Compared with the effect of flow velocity on the heat transfer coefficient, the reduction of the logarithmic average temperature difference caused by the pressure loss is the dominant factor. At this time, we need to use more shunts to increase the heat transfer. ...
