Fig. 1 is the schematic flow sheet of thermal-insulation control method one embodiment of Teat pump boiler of the present invention, and the thermal-insulation control method of described Teat pump boiler, comprises the steps:

Step S10, the current water temperature T5 gathered in water tank;

Current water temperature T5 in water tank is periodically detected by the temperature sensor be arranged in water tank.

When the accepted temperature value TL of the current water temperature T5 in water tank and setting is compared, can be that accepted water temperature temperature drop △ T5 by setting in Teat pump boiler comes indirectly to compare, △ T5 can be acquiescence or sets itself, TL=TS-△ T5, wherein TS is the water target temperature value that need be heated in the water tank of setting, and target temperature value TS is arranged voluntarily as required by user on Teat pump boiler.By by T5 and TS-△ T5(and TL) compare, determine that whether current water temperature T5 in water tank is lower than accepting temperature value TL, wherein, if T5 >=TS-△ is T5, illustrate that water temperature drop in water tank is in acceptable temperature range, do not need to heat the water in water tank, then can turn back to step S10; If T5 < TS-△ is T5, illustrate that the water temperature drop in water tank has exceeded acceptable temperature range, need to heat the water in water tank, then can send the instruction that need start heating.

When the accepted temperature value TL of the current water temperature T5 in water tank and setting is compared, can also be that accepted temperature value TL by setting in Teat pump boiler directly compares, by directly judging that the magnitude relationship of T5 and TL determines that whether current water temperature in water tank is lower than accepting temperature value.

Judge whether that the unlocking condition meeting heat pump main frame comprises: judge actual environment temperature whether within the operating ambient temperature of heat pump main frame and judge whether the current water temperature T5 in water tank drops to the open temp of heat pump host setting.

Heat pump main frame is provided with an operating ambient temperature (such as-5 DEG C ~ 50 DEG C) and an open temp.When actual environment temperature is in operating ambient temperature, heat pump main frame is allowed to open; When actual environment temperature is not in operating ambient temperature, when namely actual environment temperature is too low or too high, then heat pump main frame is not allowed to open to prevent from causing damage to heat pump main frame.The operating ambient temperature of heat pump main frame is acquiescence.When the open temp of the current water temperature in water tank higher than heat pump main frame, heat pump main frame is not opened, and when only having below the water temperature drop in water tank to the open temp of heat pump main frame, heat pump main frame just opens to heat the water in water tank.The open temp of heat pump main frame is acquiescence or user's sets itself.

In Teat pump boiler, equally open temp is provided with for electrical auxiliary heater, when the open temp of the current water temperature in water tank higher than electrical auxiliary heater, electrical auxiliary heater is not opened, when only having below the open temp that the current water temperature in water tank drops to electrical auxiliary heater, electrical auxiliary heater is just opened, to heat the water in water tank.The open temp of electrical auxiliary heater is acquiescence or user's sets itself.

When not meeting the unlocking condition of electrical auxiliary heater, then step S10 can be returned.

In step s 12, open heat pump main frame when the water in water tank is heated: if the target temperature value TS of setting heat pump main frame termination water temperature (the highest water temperature that heat pump main frame can heat) below, then close heat pump main frame after directly the water in water tank being heated to set temperature value TS by heat pump main frame; If set temperature value TS is higher than the termination water temperature of heat pump main frame, heat pump main frame is closed after then first the water in water tank being heated to termination water temperature by heat pump main frame, then can open electrical auxiliary heater and the water in water tank is continued heating, after being heated to set temperature value TS, closing electrical auxiliary heater, then can returning step S10.
