Abstract
A control method for a heat pump unit includes acquiring a first output capability set when the heat pump unit reaches a first preset energy efficiency ratio set at a current ambient temperature; acquiring a total demand load demanded by an indoor area having a heating demand or a cooling demand; and causing the heat pump unit to operate in accordance with the first output capability set when the total demand load is smaller than the first output capability set.
Claims26
A control method for a heat pump unit, wherein the method comprises the steps of:
- determining a current ambient temperature;
- acquiring a first output capability set corresponding to the heat pump unit operating at a first preset energy efficiency ratio set at the current ambient temperature;
- acquiring a total demand load demanded by an indoor area having a heating demand or a cooling demand;
- comparing the first output capability set and the total demand load;
- determining that the total demand load is smaller than the first output capability set;
- and
- causing the heat pump unit to operate in accordance with the first output capability set in response to determining that the total demand load is smaller than the first output capability set.
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.
