[0083] Normal heating: according to the inlet water temperature T IN 、T SETH and T 热泵重启回差值 The value determines whether the unit is turned on.

[0084] When the inlet water temperature T IN≤T SETH —T 热泵重启回差值 When , the unit starts to heat;

[0085] When the inlet water temperature T IN ≥T SETH When the unit is shut down at constant temperature;

[0086] When powered on for the first time, the water inlet temperature T is not calculated based on the differential value. IN <T SETH Directly turn on the machine to heat.

[0087] Specifically, according to the inlet water temperature T IN , T SETH and T 热泵重启回差值 The value of the unit is used to determine the start and stop of the unit: when the inlet water temperature T IN ≤T SETH Subtract T 热泵重启回差值 (Parameter L), unit starts heating; water inlet temperature T IN ≥T SETH When the unit is powered on for the first time, the water inlet temperature is not calculated according to the return difference value. IN <T SETH Directly start heating. When the inlet water temperature T IN ≤T SETH Subtract the heat pump restart difference (parameter L), and the unit starts heating.

[0097] Conditions for entering defrost: timed defrost according to the preset temperature threshold, and restart the timing when the compressor is turned off. When the actual coil temperature TP≤2℃ is detected, the unit heating compressor starts to accumulate continuous time. After the accumulated continuous running time is 40 minutes <parameter G>, it detects TP≤-3℃ <parameter P> and enters defrost. When the system's outdoor coil temperature Tp fails (P3), it enters timed defrost, and the defrost time is 9 minutes. When the ambient temperature is <18℃ and the unit's heating compressor runs continuously for 40 minutes <parameter G>, it enters timed defrost, and the defrost time is 9 minutes. If the ambient temperature is ≥18℃, the timing is cleared to 0. Restart the timing when the compressor is turned off.
