It is noted that compressor start mentioned in the present invention, refers to the starting of compression assembly 30, the compression assembly 30 is to realize
The main element of compressor work energy.
The compression assembly 30 includes casing, and has a chamber in the casing, for accommodating lubricating oil in the chamber.
The electricity auxiliary heating apparatus 40 is set on the outside of the chamber；Preferably, the electric auxiliary heating apparatus 40 is set to the bottom of the chamber.The electricity
Auxiliary heating apparatus 40 after powered up, for heating the lubricating oil.The environment temperature sensor 50 is for detecting the compressor institute
The environment temperature at place；And the environment temperature sensor 50 can be set to the compressor periphery, but should avoid as far as possible by
To the interference of other environmental factors, with can not environment temperature locating for objective reaction compressor.The oil temperature detection sensor 60
For detecting the temperature of lubricant in compressor.In one embodiment, the oil temperature detection sensor 60 is by detecting the machine
The temperature of shell, to react the temperature of the lubricating oil.The current transformer 70 is used to detect the operating current of compressor, with anti-
Answer the working condition of compressor.First relay 80 is electrically connected with the electric auxiliary heating apparatus 40, and first relay 80 exists
Under the control action of the circuit board 20, the on-off to 40 supply access of the electric auxiliary heating apparatus is executed.Second relay 90
It is electrically connected with the compression assembly 30, second relay 90 is under the control action of circuit board 20, to execute to compression group
The on-off of 30 supply access of part.
It should be noted that the purpose of setting of the current transformer 70 is to detect whether compressor starts into
Function；And whether compressor starts the operating current that successful standard not only only has compressor, therefore the compressor may be used also
To include compressor horsepower detection device, exhaust gas temperature sensor (for detecting the delivery temperature of compressor), evaporating temperature biography
Sensor (for detecting the evaporating temperature of heat pump system evaporator) is to react whether compressor starts success.
The circuit board 20 is passed with the controller 10, environment temperature sensor 50, current transformer 70, oil temperature detection
Sensor 60 is electrically connected；The circuit board 20 controls the electric auxiliary heating apparatus 40 and compression under the control action of the controller 10

Device 10.
In the present solution, the controller 10 by environment temperature, Lubricating Oil Temperature, compressor operating current situation to control
Make the work of the electric auxiliary heating apparatus 40；To be effectively prevented from since compressor starts not successfully, and cause electric 40 nothing of auxiliary heating apparatus
The case where effect heating；And then the problem of avoiding high frequent starting failure, influencing service life and the reliability of compressor.
Referring to figure 2., the control method of the compressor includes the following steps:
S1: environment temperature locating for detection compressor；
S2: when the environment temperature meets preset condition, electric auxiliary heating apparatus 40 is opened；
S3: after the enabling signal for obtaining compressor, compressor is started, and after the first preset duration, detection compression
Whether machine starts success；
S4: after compressor start success, the electric auxiliary heating apparatus 40 is closed.
It should be noted that the unit starting of heat pump system does not represent compressor start.By above method step it is found that
After unit powers on, first by environment temperature locating for detection compressor, to judge whether electric heating needs to open；Work as institute
When stating environment temperature and meeting preset condition, electric auxiliary heating apparatus 40 just starts to start, to heat to lubricating oil.This is because working as
When environment temperature is higher, the temperature of lubricating oil does not need further to heat, it will be able to meet compressor and normally start.Skill of the present invention
Art scheme can reduce the fruitless heating time of compressor, to reduce the power consumption of compressor.
In one embodiment, after compressor receives enabling signal, it just will do it starting.Compressor start in order to prevent
When failed, electric auxiliary heating apparatus 40 just stopped work, so that lubricating oil temperature is caused to be unable to satisfy the entry condition of compressor, from
And compressor is caused a series of consequences such as can not normally to start.Therefore setting compressor opens the first preset duration in this programme
Afterwards, whether detection compressor starts success；And after compressor start success, turn off electric auxiliary heating apparatus 40.
Further, when detecting that compressor is inactive successful, electric auxiliary heating apparatus 40 is kept to open；Return step S3.Cause
This after needing the first preset duration after compressor next time is started, is detected again when the inactive success of compressor
Whether compressor starts success；After ensuring that compressor start success, then electric auxiliary heating apparatus 40 closed.
The setting needs of first preset duration are configured according to the variety classes of compressor, and also need to consider
The use needs of the different occasions of compressor are configured.If the first preset duration setting is too long, compression will cause
Machine power consumption is higher, is unfavorable for energy conservation；If the setting of first preset duration is too short, though will cause compressor starting at
Function due to being not up to stable state, and is judged as inactive success；Either since compressor is before starting failure, also can
There are electric current, power to generate, when these indexs are detected, and determine compressor and normally start；Therefore first preset duration is set
It sets too short, will increase the probability to the erroneous judgement of the starting state of compressor.In one embodiment, if compressor is invariable frequency compressor
When, the first preset duration is preferably set as 5~10 seconds；But if compressor be frequency-changeable compressor when, due to frequency conversion compress
The start-up course of machine is longer, therefore is preferably greater than first preset duration setting 30 seconds or more.
After compressor start success, operating current can be gradually increasing, and be reached in certain current range.Therefore logical
The working current value for crossing detection compressor, that is, can determine whether compressor starts success.Therefore in the present solution, the compressor
Control method further include: it is described electricity auxiliary heating apparatus 40 open preset time after, detection compressor whether start successful step packet
It includes:
It detects and judges whether the current working current of compressor is greater than the first pre-set current value.First predetermined current
Value can be set to 0.
By whether starting successful foundation using the current working current value of the compressor as the judgement compressor
Operability and reliability it is higher.This aspect is since the operating current for detecting compressor can pass through Current Mutual Inductance
Device 70, or realize that this detection method accuracy rate and reliability are higher by current detection circuit；On the other hand, it compresses
The operating current of machine is influenced smaller by outside environmental elements, therefore can accurately and intuitively react whether the compressor starts
Success.
It will be appreciated by persons skilled in the art that the reaction successful standard of compressor start working as not just for compressor
Preceding working current value；Whether can also be greater than the first default function by detecting and judging the current power of compressor in this programme
Rate value；Or, detecting and judging whether the current delivery temperature for detecting compressor is greater than the first default outlet air temperature.Another
In embodiment, whether can also be greater than the first default evaporation temperature by detecting and judging the evaporating temperature of evaporator in heat pump system
Angle value, to judge whether compressor starts success.The first predetermined power value can be set to 0；Described first default exhaust temperature
The value of degree and the first evaporating temperature needs are set according to environment temperature and compressor model.
It is further possible to by by the evaporation of the operating current of compressor, power, delivery temperature and evaporator
Two or more in the indexs such as temperature combine, to determine whether the compressor starts success jointly, to improve
Judge whether compressor starts successful reliability and accuracy.
The control method for the compressor that technical solution of the present invention is proposed, by whether successfully starting up compressor as being
The no criterion for closing electric auxiliary heating apparatus 40 turns off electric auxiliary heating apparatus 40 to guarantee after compressor successfully starts up；It avoids
When compressor starts not successfully, it is shut off electric auxiliary heating apparatus 40, thus the defect for causing compressor further can not normally start；Cause
This technical solution of the present invention improves the preheating validity of electric auxiliary heating apparatus 40, ensure that the normal starting of compressor.
Referring to Fig. 3, as the above analysis, when environment temperature is too low, it is believed that lubricating oil in compressor
Temperature is relatively low.Therefore it is arranged described when the environment temperature meets preset condition, the step of opening electric auxiliary heating apparatus 40 includes:
Compare current environmental temperature and the first preset temperature；
When the environment temperature is less than first preset temperature, the electric auxiliary heating apparatus 40 is opened.
First preset temperature can be configured according to the type of different compressors and lubricating oil.
Further, since there are different service conditions for compressor: for example powering on, shut down after use for the first time；
Therefore in this present embodiment, by environment temperature in conjunction with the service condition of compressor, to control the work of the electric auxiliary heating apparatus 40；
To improve control flexibility of the control method of the present invention to electric auxiliary heating apparatus 40.Specific control method is described below.
When the environment temperature meets preset condition, the step of opening electric auxiliary heating apparatus 40, includes:
Compare current environmental temperature and the first preset temperature；
When the environment temperature be more than or equal to first preset temperature, and be less than or equal to the second preset temperature
When, judge whether compressor is to power on for the first time；
When compressor is to power on for the first time, controls electric auxiliary heating apparatus 40 and open.
In the present embodiment, when environment temperature is in the temperature range defined by the first preset temperature and the second preset temperature
When, number is powered on by combination compressor；To control the working condition of electric auxiliary heating apparatus 40.The present embodiment is allowed for when compression
When machine first powers on, internal lubricating oil was not preheated in advance；And when the temperature of lubricating oil is higher, it is beneficial to
The normal starting of compressor；Therefore setting is when the compressor is when first powering on, and environment temperature is in the first preset temperature
When in temperature range defined by the second preset temperature, that is, controls electric auxiliary heating apparatus 40 and open.
Further, it is described when the environment temperature be more than or equal to first preset temperature, and be less than or
When equal to the second preset temperature, judge compressor whether be the step of powering on for the first time after further include:
When compressor is second or repeatedly powers on, the shutdown duration of the compressor is obtained；
Compare the shutdown duration and the second preset duration；
When the shutdown duration is greater than second preset duration, electric auxiliary heating apparatus 40 is opened；
When the shutdown duration is less than or equal to second preset duration, S1 is returned to step.Based on above-mentioned
For embodiment it is found that when compressor starts not successfully, the electric heating can be always maintained at heated condition, thus in the present solution,
When compressor is second or repeatedly powers on, internal lubricating oil is heated.If therefore not distinguishing compressor
The problems such as powering on number, it is longer to will cause electric 40 working time of auxiliary heating apparatus, and causes compressor power consumption larger.Therefore this programme
In, further using the shutdown duration of compressor as one of Consideration, when duration of shutting down is greater than the second preset duration, this
It carves, default determines the temperature of lubricating oil to be reduced to by the temperature before the heating of electric auxiliary heating apparatus 40, it is therefore desirable to open the auxiliary heat of electricity
Device 40, to be preheated again to lubricating oil；And when duration of shutting down is less than or equal to second preset duration, it needs at this time
Return step S1 is wanted, detects environment temperature again, to judge whether to need to open electric auxiliary heating apparatus 40.
In this present embodiment, the setting of second preset duration needs to comprehensively consider the average temperature of environment of location
The amount of degree, lubricating oil types and lubricating oil；So that lubricating oil is after compressor shuts down the second preset duration, and by the auxiliary heat of electricity
Temperature before device 40 heats is suitable.
Based on the above embodiment, when environment temperature is higher, the temperature of the lubricating oil also should be higher, therefore is compressing
Before machine starting, does not need to preheat lubricating oil, compressor can be met and normally started；The control of compressor described in this programme
Method processed further include: when the environment temperature meets preset condition, controlling the step of electric auxiliary heating apparatus 40 is opened includes:
Compare current environmental temperature and the second preset temperature；
When the environment temperature is greater than second preset temperature, the electric auxiliary heating apparatus 40 is closed.
Here, the setting of first preset temperature, the second preset temperature needs to take into consideration the model of compressor, lubrication
The type of refrigerant is set in the type and heat pump system of oil.
When compressor stops working, need to detect the oil temperature of lubricating oil, to judge whether to need the oil temperature to lubricating oil
It is preheated, in order to the starting next time of compressor.Therefore in the present solution, the compressor control method, in step
After rapid S4 further include:
Whether detection compressor stops working；
When compressor stops working, the shell temperature of the oil temperature detection compressor of the lubricating oil in compressor is detected；
Whether the difference of the oil temperature and environment temperature that judge the lubricating oil is less than or equal to the first fiducial temperature；
If so, return step S1；
If it is not, the shell temperature of the step of returning to the oil temperature of the lubricating oil in detection compressor or detection compressor.
In the present solution, having represented oil temperature when the difference of oil temperature and environment temperature is less than or equal to the first fiducial temperature
It drops to close to environment temperature, it is therefore desirable to which return step S1 again detects environment temperature, is opened with determining whether to meet
Open the condition of electric auxiliary heating apparatus 40.And when the difference of oil temperature and environment temperature is greater than the first fiducial temperature, represent the oil of lubricating oil
Temperature is also higher, does not need to open electric auxiliary heating apparatus 40 and heat to lubricating oil.Therefore the present embodiment is by judging Lubricating Oil Temperature
It is efficiently avoided with determining whether to meet the condition for being again turned on electric auxiliary heating apparatus 40 to profit with the difference situation of environment temperature
The case where lubricating oil is preheated in vain thereby reduces the power consumption of compressor.
In another embodiment, it is contemplated that the oil temperature of lubricating oil is not easy to detect, therefore passes through detection compressor case
Temperature is with the oil temperature of indirect reaction lubricant in compressor.
Since the shell temperature of compressor and the oil temperature of lubricating oil have a difference, the first fiducial temperature can be passed through
Setting value to compensate the difference of the oil temperature of the shell temperature and lubricating oil so that the shell temperature and environment of the compressor
The difference of temperature can more really react the difference of the Lubricating Oil Temperature and environment temperature.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
