End, solenoid valve three are connected to the water return pipeline in net for air-source heat pump units close to set end, and the electromagnetic water discharging valve one is disconnected
Electric-opening, the solenoid valve that must be electrically turn off type, the solenoid valve two, solenoid valve three are the electricity that electric-opening type was closed, obtained in power-off
Magnet valve；Further；The defroster further includes being connected with DC water pump, DC water pump on drainpipe after solenoid valve one
It is connected with storage battery power supply device, the outlet pipe of DC water pump is connected on the inlet pipeline of net for air-source heat pump units, outlet pipe
Inlet pipeline tie point with net for air-source heat pump units is between solenoid valve two and set end；Further；The water pump
Draining branch is also provided on discharge pipe line between solenoid valve one, draining branch road is connected with solenoid valve four, solenoid valve four
By storage battery power supply, the electromagnetic water discharging valve four is the solenoid valve that type was opened, must be electrically turn off in power-off.
The positive advantageous effects of the utility model are: the present apparatus is applied on air source heat pump, is powered off suddenly
Afterwards, it powers off if it is the short time, is made by the DC water pump of storage battery power supply from water circulation is carried out between drainage pipeline water inlet pipe
Water in unit becomes running water, to will not freeze, in this way after restoring electricity, in system will not water shortage, if it is for a long time
Have a power failure, when electric power storage can not drive DC water pump to work again, can be opened after four power loss of solenoid valve, by draining branch for machine system
Water emptying in system, this defroster have taken into account the operation having a power failure for a long time with power failure system safety economy in short-term, can be fine
Apply under air source heat pump low temperature environment run when safe antifreeze in.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
In order to more fully explain the implementation of the utility model, the embodiment of the utility model is provided.These implement real
Example is only the elaboration to the utility model, does not limit the scope of the utility model.
In conjunction with attached drawing to the further details of explanation of the utility model, respectively marked in attached drawing are as follows: 1: net for air-source heat pump units；
2: outlet pipeline；3: solenoid valve two；4: inlet pipeline；5: solenoid valve three；6: drainpipe；7: Manual draining valve；8: solenoid valve one；
