In step 110, unit starting mode of pump detects water route temperature after running the first preset time t 1, by current water route temperature
As the first temperature T1.Wherein, if control device detects that environment temperature is less than environment temperature threshold value and water route temperature is less than water
Road temperature threshold then starts water pump so that unit enters anti-freezing pattern, and environment temperature threshold value is, for example, 0 °, 1 ° etc., water route temperature
Threshold value is, for example, 1 °, 2 ° etc., can be set as the case may be.First preset time t 1 for example can be 1 minute, water pump
After startup, the higher water of indoor temperature and outdoor relatively low water are mixed, when not starting compared to water pump, water route temperature
Have rising.
In step 120, if the difference of the first temperature T1 and default antifreeze temperature T0 are less than the first temperature difference threshold Ts0, in water
Pump startup detects water route temperature after running the second preset time t 2, using current water route temperature as second temperature Tr1.Wherein, T0
Preset antifreeze water temperature when entering anti-freezing pattern operation for unit, due to water pump operation itself can work consuming heat dissipation, heat dissipation can be slow
Water temperature is heated, therefore, after the starting mode of pump t2 times, it is also necessary to a water route temperature is surveyed again, subsequently to judge whether to need
Start compressor, wherein t2 is, for example, 30 minutes.
It is opened in step 130 if the difference of second temperature Tr1 and the first temperature T1 are less than or equal to second temperature threshold value Trs0
Dynamic compressor.Wherein, if Tr1-T1>Trs0 then illustrates that water system load is smaller, being capable of less energy without opening compressor
Consumption；If Tr1-T1≤Trs0, illustrate that water system load is bigger, only starts water pump circulation waterway and be not enough to be promoted water route in advance
Therefore constant temperature degree needs unlatching compressor to be heated at this time, avoid the low energy consumption in water pump long-play heat dissipation heating water route
Cycle.
In this embodiment, after unit starting mode of pump runs the first preset time, Ruo Shui Road temperature and default antifreeze temperature
The difference of degree is less than the first temperature difference threshold, then allows water pump to continue to run with, but be not turned on compressor at this time, in starting mode of pump operation the

Start if environment temperature is less than environment temperature threshold value and water route temperature is less than water route temperature threshold in step 210
Water pump enters anti-freezing pattern so as to unit.Wherein, for unit under shutdown or standby mode, unit need to be in energized state, control
The environment temperature and water route temperature that device processed is detected according to temperature sensing package judge whether unit needs to enter antifreeze operational mode, if needing
It wants, then starts water pump automatically.
In step 220, starting mode of pump detects water route temperature T1 after running the first preset time t 1.Wherein, first it is default when
Between t1 for example be about 1 minute.
In step 230, judge that the first temperature T1 and the difference of default antifreeze temperature T0 are less than the first temperature difference threshold Ts0, if not
It is to then follow the steps 240, if so, thening follow the steps 250.Mainly judge water route accumulation of heat at this time, wherein if the difference of T1-T0 is got over
Greatly, then illustrate that water route accumulation of heat is more, if the difference of T1-T0 is smaller, illustrate that water route accumulation of heat is fewer.
In step 240, control water pump is out of service, and unit exits antifreeze operational mode.After water pump is out of service, if crossing one
Section time, the environment temperature and water route temperature that control device detect again according to temperature sensing package judge whether unit needs into antifreeze
Operational mode, if desired, then start water pump automatically, water pump after run the t1 times, need to judge again water route temperature T (n) and
Logical relation between the preset antifreeze temperature T0 of unit, it is out of service to determine whether to control water pump, prevent water pump always
In invalid radiating state, to rationally control the water pump operation time.Wherein, T (n) is to be examined after water pump n-th starts the t1 times
The water route temperature of survey.
In step 250, pump continues to run with, and water route temperature Tr1 is detected after starting mode of pump runs the second preset time t 2.
Wherein, the t2 times are about 30 minutes, due to water pump operation itself can work consuming heat dissipation, water route temperature can also rise.
In step 260, judge whether the difference of Tr1 and T1 is more than second temperature threshold value Trs0, if so, 240 are thened follow the steps,
Otherwise, step 270 is executed.If Tr1-T1>Trs0 then illustrates that not needing water pump continues to run with, and reduces water pump long-play and dissipates
The low energy consumption cycle in heat heating water route.When water pump n-th starts the t2 times, the water route temperature Tr (n) for judging detection need to be continued
Relationship between the difference and second temperature threshold value Trs0 of T (n), if unit cannot detect compressor start service condition,
Then enter water pump circulation anti-freezing state always, at this time at low ambient temperatures, water route temperature can continue to reduce.
In step 270, starts compressor, illustrate that water system load is larger at this time, water pump and compressor are both needed to run.
In step 280 water route temperature Ts is detected after starting mode of pump operation third preset time t 3.Compressor start is transported
Row heating, water route constant temperature increase, need to detect water route temperature in real time.
In step 290, judge whether water route temperature Ts is more than load temperature, if so, 2100 are thened follow the steps, otherwise,
Unit operation for a period of time after, continue detect water route temperature.Wherein, environment temperature when load temperature can be according to compressor start
Degree, default environment temperature initial value and default antifreeze temperature determine.For example, in the calculating of air conditioning performance rule, environment temperature is got over
Height, water temperature are higher, and the antifreeze efficiency of unit is bigger；Environment temperature is lower, water temperature is lower, and the antifreeze efficiency of unit is smaller.Inventor passes through
Cross a large amount of experimental analyses, it is believed that can determine load temperature according to formula T0+k (Th-Th0)；Wherein, T0 is to preset antifreeze temperature
Degree, environment temperature when Th is compressor start, Th0 are default environment temperature initial value, and k is fitting coefficient, by testing number
According to determination.If Ts is less than T0+k (Th-Th0), unit continues heating operation, and until water route, temperature is increased to satisfaction and exits
Until condition.
It will be understood by those of skill in the art that T0+k (Th-Th0) is only used for illustrating, load temperature can also basis
Other correlation formulas of environment temperature, default environment temperature initial value and default antifreeze temperature when compressor start determine.
In step 2100, controls water pump and compressor is out of service.At this point, unit exits antifreeze operational mode.
In this embodiment, according to environment temperature and the relationship of the water route temperature and temperature threshold of detection, in water system
When load is smaller, allow water pump operation as possible, when water system load is larger, start compressor in time, and rationally control water pump and
The run time of compressor can reduce water pump, compressor power consumption, improve anti-freezing energy-saving efficiency.In addition, basis in the embodiment
The operating condition of unit under varying environment temperature load goes out the best antifreeze control water of unit according to unit fitting experimental data

Water route temperature is detected after starting the second preset time of operation, using current water route temperature as second temperature.Temperature detecting unit 310
Can be temperature sensing package or temperature sensor, or the component from temperature sensing package or temperature sensor acquisition water route temperature.Wherein,
One preset time t 1 for example can be 1 minute, after starting mode of pump, and the higher water of indoor temperature and outdoor relatively low water are mixed
It closes, when not starting compared to water pump, water route temperature has rising.In addition, due to water pump operation itself can work consuming heat dissipation, heat dissipation
It can be slowly heated water temperature, therefore, after the starting mode of pump t2 times, it is also necessary to a water route temperature is surveyed again, subsequently to judge to be
It is no to need to start compressor.
If difference of the device control cell 320 for second temperature Tr1 and the first temperature T1 is less than or equal to second temperature threshold value
Trs0 then starts compressor.Wherein, if Tr1-T1>Trs0 then illustrates that water system load is smaller, without opening compressor, energy
Enough less energy consumptions；If Tr1-T1≤Trs0, illustrate that water system load is bigger, only starts water pump circulation waterway and be not enough to be promoted
Water route is to predetermined temperature, therefore, unlatching compressor is needed to be heated at this time, avoids water pump long-play heat dissipation heating water route
Low energy consumption cycle.
In this embodiment, after unit starting mode of pump runs the first preset time, Ruo Shui Road temperature and default antifreeze temperature

Border temperature, default environment temperature initial value and default antifreeze temperature determine.For example, inventor analyzes by many experiments, it is believed that
Load temperature can be determined according to formula T0+k (Th-Th0)；Wherein, T0 is to preset antifreeze temperature, when Th is compressor start
Environment temperature, Th0 is default environment temperature initial value, and k is fitting coefficient, is determined by experimental data.If Ts is less than T0+
K (Th-Th0), then unit continue heating operation, until water route, temperature is increased to until meet exit criteria.
It will be understood by those of skill in the art that T0+k (Th-Th0) is only used for illustrating, load temperature can also basis
Other correlation formulas of environment temperature, default environment temperature initial value and default antifreeze temperature when compressor start determine.
In addition, if device control cell 320 is additionally operable to the first temperature is more than or equal to the first temperature with antifreeze temperature difference is preset
Poor threshold value, if alternatively, it is out of service to control water pump more than second temperature threshold value for second temperature and the first temperature difference.
If device control cell 320 is additionally operable to environment temperature less than environment temperature threshold value and water route temperature is less than water route temperature
Threshold value then starts water pump so that unit enters anti-freezing pattern.
