Technical field
The present invention relates to the technical fields of air conditioner heat pump system, refer in particular to a kind of based on water temperature control bent axle heating
Control method with start and stop.
Background technology
Existing air conditioner heat pump system has the operation by environment temperature and compressor start or closing control crankshaft heating band.
When environment temperature is less than certain value, compressor start, crankshaft heating band is closed；Compressor is closed, and crankshaft heating band is opened, mesh
Be that compressor and freeze oil is made to keep certain temperature, this control mode is possible to because environment temperature is too low, in compressor start
When close crankshaft heating band, compressor exhaust temperature and suction temperature is too low compressor occurs and return liquid or the increase of refrigeration oil resistance etc.
Defect；Compressor closes and opens crankshaft heating band, and heating tape is opened too early to be possible to be higher than bent axle because of compressor surface temperature
Heating tape surface temperature leads to energy waste so that heat cannot absorb.
Air-source hot-water heating system generally controls being turned on and off for host by water tank temperature, when water temperature drops to set temperature
During value, host is opened, when water temperature heating is to set temperature value, Host Shutdown；Host start and stop interval time is related with water consumption.
If pass through environment temperature and host start-up and shut-down control crankshaft heating band, it is possible to cause crankshaft heating band up to a hundred small before host unlatching
When in opening, energy waste can be caused in this way.

It between the temperature value for judging environment temperature Tr, water temperature Tw, compressor exhaust temperature Tq setting corresponding with control system
Relationship control the crankshaft heating band to run.
Further, after crankshaft heater opens heating, if meeting environment temperature Tr ＞ Trs or water temperature Tw ＞
Tws or compressor exhaust temperature Tq ＞ Tqs any one, crankshaft heater is then closed.
The present invention uses above-mentioned scheme, and advantage is：1）Reduce energy consumption：Pass through environment temperature, water temperature
With the unlatching of compressor exhaust temperature control crankshaft heating band, crankshaft heating band is avoided to open for a long time or too early, reduces energy
Waste.2）Extend compressor service life：Crankshaft heating band is controlled by environment temperature, water temperature and compressor exhaust temperature
Closing, prevent crankshaft heating band from closing too early and compressor caused to return liquid or compressor and freeze oil resistance and is become larger, extend compression
Machine service life.
Description of the drawings
Fig. 1 is the crankshaft heating band control method logical schematic of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is further illustrated.
Referring to shown in attached drawing 1, in the present embodiment, a kind of controlling party based on water temperature control crankshaft heating band start and stop
Method by the startup or closing of environment temperature Tr, water temperature Tw and compressor exhaust temperature Tq co- controlling crankshaft heaters, rises
To reduction crankshaft heating band energy consumption and extend compressor service life.
In order to ensure air conditioner heat pump system, environment temperature is set as opening by normal operation, the control system at low ambient temperatures
The precondition of dynamic crankshaft heating tape；Crankshaft heating band unlatching too earlyer than host in order to prevent, the control system is by water temperature
It is set as one of necessary condition of crankshaft heating band unlatching；Crankshaft heating band is closed too early after compressor start in order to prevent,
Lead to the closing that compressor returns liquid or refrigeration oil is sticky, and control system passes through compressor exhaust temperature control crankshaft heating band；For
Preventing crankshaft heating band from being opened too early after compressor closing leads to energy waste, and it is bent that control system passes through delivery temperature control
The unlatching of axis heating tape.
In conjunction with specific embodiment to the left further explanation of the air conditioner heat pump system of the application, the air-conditioning heat pump of the present embodiment
For air-source hot-water heating system, the implementation of crankshaft heating band start and stop function in air-source hot-water heating system is as follows：Air-source hot water system
System is during water heating, and when water tank temperature reaches setting value, compressor is closed, and system is out of service；When under water tank temperature
System opens heating operation when dropping to system set point temperature value.It needs to use crankshaft heating band under low ambient temperature, before compressor start
To its heating and thermal insulation, increase to prevent compressor and freeze oil resistance.If water tank temperature declines very slow.Bent axle is controlled by water tank temperature
Heating tape is turned on and off, and the unlatching water temperature T ws of crankshaft heating band is set as control system opens water temperature plus △ t, △ t
Adjustable, when water tank fluctuating temperature is big, then △ t are set smaller；When water tank fluctuating temperature is smaller, △ t can set larger.In this way
Mode, as environment temperature Tr≤Trs, delivery temperature Tq≤Tqs, when water temperature Tr drops to Tws, crankshaft heating band is opened
Heating and thermal insulation is carried out to compressor.The compressor start when water tank temperature drops to set temperature, unit heat tank hot water.
As compressor exhaust temperature Tq ＞ Tqs, crankshaft heating band is closed.Song is controlled by the water tank water temperature of air-source hot-water heating system
Axis heating tape is turned on and off, and crankshaft heating band is not only avoided to close too early and increases compressor start resistance, while avoid song
Axis heating tape is opened too early leads to energy waste.
In the present embodiment, a kind of control method based on water temperature control crankshaft heating band start and stop, the control method
Include following steps：

S20. control system judges the relationship between environment temperature Tr and presetting environment temperature Trs；
If S30. during environment temperature Tr≤Trs, control system then judge water temperature Tw and presetting water temperature Tws it
Between relationship；
If S40. during water temperature Tw≤Tws, control system then judges compressor exhaust temperature Tq and presetting compressor
Relationship between delivery temperature Tqs；
If S50. compressor exhaust temperature Tq≤Tqs, crankshaft heater opens heating.
Further, in step S20, if environment temperature Tr ＞ Trs, crankshaft heating band remain off.
Further, in step s 30, if water temperature Tw ＞ Tws, crankshaft heating band remain off.
Further, in step s 40, if compressor exhaust temperature Tq ＞ Tqs, crankshaft heating band remain off.
Further, in step s 50, after crankshaft heating band opens heating, control system then judges environment temperature Tr, water
Relationship between the temperature value of temperature Tw, compressor exhaust temperature Tq setting corresponding with control system controls bent axle to heat
Band operation.
Further, after crankshaft heater opens heating, if meeting environment temperature Tr ＞ Trs or water temperature Tw ＞
Tws or compressor exhaust temperature Tq ＞ Tqs any one, crankshaft heater is then closed.
Pass through above-mentioned control method so that the unlatching of crankshaft heating band is by environment temperature Tr, water temperature Tw and compressor
Delivery temperature Tq co- controllings.The unlatching of crankshaft heating band is controlled by water temperature, end thermal load demands hour can be prevented
Crankshaft heating band is opened and leads to energy waste too early, prevents crankshaft heating band from being opened too early before compressor start to play.
Control system controls the closing of crankshaft heating band by environment temperature and compressor exhaust temperature, prevents crankshaft heating band from compressing
Machine is closed too early after opening, and is increased to prevent compressor by liquid hammer or freezing oil viscosity, resistance；Control system by environment temperature and
