Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as the limit to the present invention
It is fixed.
Fig. 1 is the structural representation of small air source heat pump heating system according to embodiments of the present invention, as shown in figure 1,
Water system sketch is shown in the dotted line frame of right side, water system includes：Water-side heat, water pump, air bleeding valve, water flow switch, peace
Full valve, expansion drum, water collecting and diversifying device etc..When installation and debugging or after-sales service carry out water system emptying, in order to save the energy
Efficiency is emptied with water system is improved, the present invention proposes a kind of water system emptying control program, carried out in detail below by embodiment
Introduce.
Fig. 2 is the flow chart of water system emptying control method according to embodiments of the present invention, as shown in Fig. 2 this method bag
Include following steps (step S201- step S202)：
Step S201, after confirming that unit is off-mode, triggering starts the emptying pattern of water system；
Step S202, under emptying pattern, water pump and air bleeding valve are opened in control, to realize the row of water-system pipeline air
It is empty.
In the present embodiment, using the emptying of water system operation as one functional mode of unit, do not started shooting operation in unit
On the premise of start emptying pattern, reduce water system emptying when power consumption, save the energy.
In order to simplify operation, emptying pattern can be entered by panel operation, improves the efficiency of water system emptying.For example,
The step of above-mentioned triggering startup emptying pattern, can be realized by following preferred embodiment：The startup of user is received by panel
Signal；Triggered according to enabling signal and start emptying pattern.That is, user operates on panel can start emptying pattern, and operation is non-
Often easy, Experience Degree is high.In the present embodiment, panel can be display board or remote control panel, and the present invention does not make to this
Limit, as long as the operational order of user can be received, trigger corresponding pattern.
After triggering starts emptying pattern, control unlatching water pump, controls and opens air bleeding valve after the specified duration that can be delayed.This
The unlatching of place's water pump and air bleeding valve in no particular order, in practical operation, generally can be positioned at the row of being then turned on after water pump is opened
Air valve, so as to effectively carry out the emptying of air in water-system pipeline.It should be noted that now unit is in off-mode, because
This, other complete machines load (such as compressor, blower fan, four-way valve electric expansion valve etc.) is not turned on.So as to reduce unit load
Power consumption, save the energy.Certainly, above-mentioned specified duration can be set according to demand, such as may be configured as 10 seconds.
, can be after triggering start emptying pattern in order to avoid user misoperation, control locking panel, to cause panel
The start and stop of other patterns in addition to emptying pattern can not be triggered.Enter after emptying pattern, panel locking, it is impossible into other
Mode of operation.
In addition, during the operation of emptying pattern, the failure detection operations of water system can be performed；According to testing result control
The keying of water pump processed.Specifically, if testing result, which is water system, specified type failure occurs, control switches off the pump；If
Testing result is failure of the water system appearance in addition to specified type failure, or, testing result is water system fault-free, then controls
Water pump processed continues to run with.Above-mentioned specified type failure comprises at least one below：Water flow switch protection, communication failure, water pump event
Barrier.Based on this, avoid the continuing to run with for water pump when water system breaks down that the problem of more serious occurs.Detecting water system
After system breaks down, Display panel corresponding failure can be passed through.So as to remind maintenance personal to find failure problems in time, inspection in time
Repair.
After the air emptying in the pipeline of water system, user can be controlled by panel and exit the emptying pattern.
Or automatically exit from the emptying pattern after may be provided at the emptying mode operation preset duration.Above-mentioned preset duration can root
Set, such as may be configured as 45 minutes according to actual demand.
After emptying pattern is exited, close air bleeding valve and water pump, panel unlock, can trigger opening for other mode of operations
Stop.
In the present invention, a functional mode of the water system emptying operation as unit：Emptying pattern, panel can be passed through
Trigger unlatching/closing of emptying pattern.Panel could enter emptying pattern in the power-offstate.
Fig. 3 is water system emptying control flow chart according to embodiments of the present invention, as shown in figure 3, the flow is including following
Step (step S301- step S315)：
Step S301, flow start.
Step S302, judge whether unit is off-mode by display board (or remote control panel)；If it is, perform step
Rapid S304, if it is not, then performing step S303.
Step S303, emptying pattern can not be triggered.
Step S304, if trigger the emptying pattern of water system；If it is, step S305 and step S306 is performed, such as
Fruit is no, then performs step S301.
Step S305, lock display board, it is impossible to enter back into other mode of operations.
Opened after step S306, water pump delay t1, the load of other complete machines (such as compressor, blower fan, four-way valve electronic expansion
Valve etc.) it is not turned on.For example, t1 could be arranged to 10 seconds.
Step S307, open air bleeding valve.
Step S308, if detect water flow switch protection, complete machine communication failure, fault of water pump；If it is, perform step
Rapid S309, if it is not, then performing step S310.
Step S309, switches off the pump, and shows corresponding failure on the display panel.Then step S312 is performed.
Step S310, water pump continue the state kept it turned on.If detecting other failures, display is corresponding on the display panel
Failure but water pump is kept it turned on.
Step S311, emptying pattern is exited by display board, or, voluntarily exited after emptying mode operation t2 durations.Example
Such as, t2 may be configured as 45 minutes.
Step S312, close air bleeding valve.
Step S313, exit emptying pattern.
Step S314, switches off the pump.
Step S315, display board unlock, and can enter other mode of operations.
The present embodiment starts emptying pattern on the premise of unit does not start shooting operation, power consumption when reducing water system emptying,
Save the energy.Emptying pattern is operated into by display board, it is simple to operate, improve the efficiency of water system emptying.
Control method is emptied corresponding to the water system of Fig. 2 introductions, present embodiments provides a kind of water system emptying control dress
