Claim 20:
21. A control method for a heat pump unit, wherein the control method comprises:
determining: (i) the heat pump unit reaches a first preset energy efficiency ratio set at a current ambient temperature; (ii) there is a heating demand or a cooling demand; and (iii) it is necessary to cause a compressor of the heat pump unit to operate; and
operating the heat pump unit in accordance with an output capability set that is not lower than the output capability set in response to determining: (i) the heat pump unit reaches the first preset energy efficiency ratio set at the current ambient temperature; (i) there is a heating demand or a cooling demand; and (iii) it is necessary to cause the compressor of the heat pump unit to operate.
