8. heat pump adjusting means according to claim 6, it is characterised in that the current operation mode includes heating mould
Formula；
The first corresponding relation of interval and heat pump the peak frequency of ambient temperature includes under heating mode：
If ambient temperature heats the low ambient temperature for starting compensating for less than or equal to default, the peak frequency of heat pump is default system
Hot low environment compensates highest goal frequency；
If ambient temperature heats the low ambient temperature that starts compensating for and less than the default height for heating and shutting down compensation more than default
Ambient temperature, the peak frequency of heat pump heats compressor peak frequency for default；
If more than or equal to the default high environment temperature for heating and shutting down compensation, the peak frequency of heat pump is default system to ambient temperature
The high ambient compensation highest goal frequency of heat；
Wherein, the low ambient temperature for starting compensating for is heated<The high environment temperature for shutting down compensation is heated, compressor peak frequency is heated
≤ low environment compensation highest goal frequency is heated, heat high ambient compensation highest goal frequency≤heat compressor peak frequency.
9. heat pump adjusting means according to claim 6, it is characterised in that also including being connected with the detection module successively
Target superheat degree obtain module and aperture regulation module；
The target superheat degree obtains module to be used for when current operation mode is heating mode, according under default heating mode
Second corresponding relation of the target superheat degree of ambient temperature and heat pump, obtains the target superheat degree corresponding to current environmental temperature,
Target superheat degree changes with the change of ambient temperature in wherein described second corresponding relation；
The aperture regulation module is used to obtain the actual degree of superheat of heat pump, according to the actual degree of superheat and the target mistake for obtaining
Temperature is adjusted to the aperture of the electric expansion valve of the heat pump.
10. heat pump adjusting means according to claim 9, it is characterised in that ambient temperature and heat pump under heating mode
Second corresponding relation of target superheat degree includes：
If less than default end degree of superheat compensation ambient temperature, the target superheat degree of heat pump is the default degree of superheat to ambient temperature
The sum of compensation difference and the default degree of superheat；
If ambient temperature is more than or equal to default end degree of superheat compensation ambient temperature and less than or equal to the default beginning degree of superheat
Compensation ambient temperature, the target superheat degree=proportionality coefficient * ambient temperatures+constant of heat pump；
If more than default beginning degree of superheat compensation ambient temperature, the target superheat degree of heat pump is default overheated to ambient temperature
Degree；
Wherein, proportionality coefficient=degree of superheat compensation difference/(end degree of superheat compensation ambient temperature-beginning degree of superheat compensation environment
Temperature), the constant=default degree of superheat-proportionality coefficient * starts degree of superheat compensation ambient temperature；Terminate degree of superheat compensation environment temperature
Degree<Start degree of superheat compensation ambient temperature.
