if so, adjusting the running frequency of the matched water pump according to the temperature difference of the supplied water and the returned water;
if not, all the water pumps are started at the lowest running frequency.
7. The method according to claim 6, wherein the determining that the freeze protection mode needs to be turned on is:
and if the user starts the anti-freezing function or the current outdoor environment is lower than the threshold value, determining that the anti-freezing mode needs to be started.
8. The utility model provides an air source heat pump and water pump coordinated control system which characterized in that includes:
the detection module is used for detecting the supply and return water temperature difference of all the air source heat pumps which are started to operate;
the adjusting module is used for keeping the current running state of any air source heat pump if the temperature difference between the water supply and the water return is within a preset temperature change range; otherwise, adjusting the operating frequency of the water pump matched with the air source heat pump according to a preset rule until the temperature difference of the supplied water and the returned water is within a preset temperature change range.
9. The utility model provides an air source heat pump and water pump coordinated control system which characterized in that includes:
at least one air source heat pump and its matched water pump;
a processor;
a memory for storing processor-executable instructions;
wherein the processor is configured to:
detecting the temperature difference of supply water and return water of all the air source heat pumps which are started to operate;
for any air source heat pump, if the temperature difference between the water supply and the water return is within a preset temperature change range, the current operation state of the air source heat pump is kept; otherwise, adjusting the operating frequency of the water pump matched with the air source heat pump according to a preset rule until the temperature difference of the supplied water and the returned water is within a preset temperature change range.
10. An electronic device, comprising:
the system comprises a communication module, a processor and a memory, wherein the memory stores program instructions;
the processor is configured to execute program instructions stored in the memory to perform the method of any of claims 1 to 7.
