[0033] Current air energy heat pump products make many attempts to couple with solar energy, most of which use the principle of conventional solar water heaters to transfer solar energy to water, and then use a heat exchanger to transfer the heat in the water to air for use by the air energy heat pump, or directly heat the water at the user side for use. This type of range extender heat pump needs to convert heat energy into a certain medium, and then process it through the heat exchanger of the heat pump unit before supplying it to the heat pump unit.
