Step 33 is repeated, that is, switches to low-grade location starting.
Pump water system operation must have minimal circulation water capacity in the above embodiment of the present invention, and water flow switch can detecte
The reason of minimal circulation water capacity of circulation, the above embodiment of the present invention carries out water system exhaust, is: (1) in complete machine
It sets circulating water motor that circulation shielding water pump is taken and profit changes bearing, therefore anhydrous and exsiccosis pump motor overheat,
The reliabilities such as the bad abrasion of bearing lubrication are very poor.(2) anhydrous simultaneously and exsiccosis easily leads to the anti-mistake of complete machine for complete machine operation
Thermal protection, frequent start-stop etc., the damage of the core components such as heat exchanging device are larger.(3) pump water system recirculated water is refrigerating medium, nothing
Water and exsiccosis lower end refrigerating amount are insufficient, and comfort is poor, and energy consumption is high.
In some embodiments of the invention, in the water pump gear switch of the high tap position of step 33 and step 34, low-grade location
Such as water flow switch is unprotected in exhaust process, thens follow the steps 35, that is, control antifreeze (the water pump period in control stage of complete machine second
Property operation the antifreeze detection-phase of dynamic).
In some embodiments of the invention, it is cut in the anti-freezing water pump of step 33 and step 34 starting high tap position, low-grade location
During changing starting, the complete machine antifreeze control method of the anti-freezing water pump starting water flow switch detection-phase can also include:
Step 341, judge that water pump starting high tap position, low-grade location switching start whether continuous pre-determined number fails to remove water
Flow switch protection.
Step 342, start continuous pre-determined number in water pump starting high tap position, low-grade location switching and fail to remove water flow switch
In the case where protection, water pump high tap position operation feedback water pump input average current I is judgedMean heightFeedback water is run with water pump low-grade location
Pump input average current IIt is average lowDifference △ IIt is averageWhether predetermined value △ I is more than or equal to.
Step 343, feedback water pump is run in water pump high tap position input average current IMean heightIt runs and feeds back with water pump low-grade location
Water pump inputs average current IIt is average lowDifference △ IIt is averageIn the case where predetermined value △ I, control pump water system skips the
Two antifreeze control stages executed step 36.
Step 344, feedback water pump is run in water pump high tap position input average current IMean heightIt runs and feeds back with water pump low-grade location
Water pump inputs average current IIt is average lowDifference △ IIt is averageIn the case where less than predetermined value △ I, it is determined as unit anhydrous state, executes
Step 37.
Step 35, control complete machine normally enters the second antifreeze control stage (antifreeze detection of the dynamic of water pump cycling service
Stage).
Step 36, control complete machine is directly entered the third antifreeze control stage, wherein the third antifreeze control stage is heat
The pump operation antifreeze stage.The antifreeze operation of heat pump heating mode stops until there is unrecoverable failure in the above embodiment of the present invention
Machine, so as to utmostly reduce the bursting by freezing risk of machine heat exchanger in unit.
Step 37, control pump water system complete machine exits third antifreeze control stage (operation of heat pump antifreeze stage).
The anti-freezing water pump that the above embodiment of the present invention winter anti-freezing intelligent dynamic detection is taken starts high tap position, low-grade location is cut
Starting is changed, and recirculated water high flow rate drives water route to stand an air of feeling suffocated of choking with resentment for a long time, air smashed by recirculated water high flow rate
Pass through engineering side automatic exhaust device discharge system.The above embodiment of the present invention anti-freezing water pump high tap position, low-grade location switching starting
Maintain the efficiently automatic exhaust of low-grade location control operation, can solve winter automatic freezing-protective occur water flow switch protection cause winter from
It moves antifreeze failure, the stifled damage of pump water system ice, increase the technical issues of pump water system maintenance cost.
Fig. 4 is the schematic diagram of the second antifreeze some embodiments of control stage antifreeze control method of the invention.Fig. 5 is the present invention
The control timing diagram of second antifreeze control stage some embodiments.Preferably, the present embodiment can be by the antifreeze control of the present invention
Device executes.As shown in figure 4, the antifreeze control method may comprise steps of:
Step 41, meet the first predetermined condition in control parameter and pump water system complete machine enters water pump cycling service
The antifreeze detection-phase of dynamic in the case where, obtain water pump cycle dynamics operation starting before inflow temperature TBefore water inletWater temperature out

It is found by the applicant that the relevant technologies have the following technical problems: the winter automatic freezing-protective of the pump water system of the relevant technologies
Control takes engineering side to configure antifreeze temperature sensing package, and the winter shutdown that heating and ventilating pipeline and heating terminal are tested in engineering debugging process is quiet
Water temperature minimum point is set, while entering setting default value according to the setting of the configuring condition of heating and ventilating pipeline and heating terminal is antifreeze.Pass through
Detect antifreeze temperature sensing package temperature value variation, after antifreeze temperature sensing package detected value is antifreeze lower than control logic enters setting value, complete machine
It is controlled into winter automatic freezing-protective.Units' installation mainstream takes combined type to install in practical engineering application, the antifreeze temperature sensing package of complete machine
The configuration of engineering side is lack of standardization, chooses that installation site is unreasonable to be caused mounting technique specification to be implemented not in place to easily lead to winter and prevent automatically
Freeze failure.
The engineering pipeline and tip designs situation of the relevant technologies are taken substantially and borrow old scattered coal arcola or electrically heated
Old pipe network and end carry out engineered.Old pipe network heat preservation and building maintenance structure are poor, and complete machine pipeline does not have isothermal holding etc., whole
A system pipe network thermal leakage ratio is higher, and the entire severe temperature drop point of pipe network extreme weather is more easily to cause single antifreeze temperature sensing package using essence
Degree deficiency causes winter automatic freezing-protective to fail.
The anti-control stage of the second of the above embodiment of the present invention (the antifreeze detection-phase of the dynamic of water pump cycling service) will
Each being consistent property of temperature drop point of system circulating water, so as to prevent antifreeze temperature sensing package detection lag or detection not in time
The problem of causing water system part ice stifled, thus causing the failure of winter automatic freezing-protective.
Fig. 6 is the schematic diagram of the antifreeze some embodiments of control stage antifreeze control method of third of the present invention.Preferably, this reality
Applying example can be executed by freezing protection control device of the present invention.As shown in fig. 6, the antifreeze control method may comprise steps of:
Step 61, in the case where the dynamic that pump water system complete machine enters water pump cycling service antifreeze detection-phase,
Judge whether control parameter meets the second predetermined condition or third predetermined condition.
