The compression assembly 30 includes having in casing, and the casing in a chamber, the chamber for accommodating lubricating oil.
The electric auxiliary heating apparatus 40 are on the outside of the chamber；Preferably, the electric auxiliary heating apparatus 40 are located at 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 used to detect the compressor institute
The environment temperature at place；And the environment temperature sensor 50 can be located at the compressor periphery, but should try one's best avoid by
To the interference of other environmental factors, with environment temperature that can not be residing for objective reaction compressor.The oil temperature detection sensor 60
Temperature for detecting 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 for the operating current for detecting 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 break-make to the electric supply access of auxiliary heating apparatus 40 is performed.Second relay 90
Electrically connected with the compression assembly 30, second relay 90 is under the control action of circuit board 20, to perform to compression group
The break-make of the supply access of part 30.
Herein it should be noted that the setting purpose of the current transformer 70 is to detect whether compressor starts into
Work(；And whether compressor starts the operating current that successful standard not only only has compressor, therefore the compressor may be used also
To be passed including compressor horsepower detection means, exhaust gas temperature sensor (being used for the delivery temperature for detecting compressor), evaporating temperature

Device 10.
In this programme, the controller 10 is by the operating current situation of environment temperature, Lubricating Oil Temperature, compressor to control
Make the work of the electric auxiliary heating apparatus 40；So as to be effectively prevented from because compressor starts not successfully, and cause the electric nothing of auxiliary heating apparatus 40
Imitate the situation of heating；And then avoid the problem of high frequent starts failure, the life-span of influence compressor and reliability.
Fig. 2 is refer to, the control method of the compressor comprises the following steps：
S1：Detect the environment temperature residing for compressor；
S2：When the environment temperature meets preparatory condition, electric auxiliary heating apparatus 40 are 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 are closed.
It should be noted that the unit starting of heat pump does not represent compressor start.From above method step,
On unit after electricity, first by detecting the environment temperature residing for compressor, to judge whether electrical heating needs unlatching；Work as institute
When stating environment temperature and meeting preparatory condition, electric auxiliary heating apparatus 40 just start to start, so as to be heated to lubricating oil.This is due to work as
When environment temperature is higher, the temperature of lubricating oil need not be heated further, it becomes possible to met compressor and normally started.Skill of the present invention
Art scheme can reduce the fruitless heating time of compressor, so as to reduce the power consumption of compressor.
In one embodiment, after compressor receives enabling signal, it can just be started.In order to prevent compressor start
When failed, electric auxiliary heating apparatus 40 just stopped work, so that cause lubricating oil temperature can not meet the entry condition of compressor, from
And cause compressor a series of consequences such as can not normally start.Therefore compressor is set to open 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 the not actuated success of compressor, electric auxiliary heating apparatus 40 are kept to open；Return to step S3.Cause
This is when the not actuated success of compressor, it is necessary to after the first preset duration after compressor next time is started, detect again
Whether compressor starts success；Ensure that after compressor start success, then electric auxiliary heating apparatus 40 are closed.
The setting of first preset duration needs to be configured according to the variety classes of compressor, and also needs to consider
The use of the different occasions of compressor needs to be configured.If it is long that first preset duration is set, compression can be caused
Machine power consumption is higher, is unfavorable for energy-conservation；If the setting of first preset duration is too short, even if compressor can be caused to start into
Work(, due to being not up to stable state, and is judged as not actuated success；Either because compressor is before failure is started, also can
There are electric current, power to produce, when these indexs are detected, and judge compressor and normally start；Therefore first preset duration is set
Put too short, the probability of the starting state erroneous judgement to compressor can be increased.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 compression
The start-up course of machine is longer, therefore is preferably more than first preset duration setting more than 30 seconds.
After compressor start success, its operating current can be gradually increasing, and be reached in certain current range.Therefore it is logical
Cross the working current value of detection compressor, you can judge whether compressor starts success.Therefore in this programme, described compressor
Control method also include：The electric auxiliary heating apparatus 40 are opened after preset time, and whether detection compressor starts successful step bag
Include：
Detect and judge whether the current working current of compressor is more 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 due to that the operating current of detection compressor can pass through Current Mutual Inductance
Device 70, or realized by current detection circuit, this detection method accuracy rate and reliability are higher；On the other hand, compress
The operating current of machine is influenceed 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；Can also be by detecting and judging whether the current power of compressor is more than the first default work(in this programme
Rate value；Or, detect and judge whether the current delivery temperature for detecting compressor is more than the first default outlet air temperature.Another
, can also be by detecting and judging whether the evaporating temperature of evaporator in heat pump is more than the first default evaporation temperature in embodiment
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 to be 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 are combined, to judge whether the compressor starts success jointly, so as 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, to ensure after compressor is successfully started up, turns off electric auxiliary heating apparatus 40；Avoid
When compressor starts not successfully, electric auxiliary heating apparatus 40 are shut off, so as to cause the defect that compressor further can not normally start；Cause
This technical solution of the present invention improves the preheating validity of electric auxiliary heating apparatus 40, it is ensured that the normal startup 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 set described when the environment temperature meets preparatory 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 are opened.
First preset temperature can be configured according to the species of different compressors and lubricating oil.
Further, because compressor has different service conditions：Situations such as example after first upper electricity, use shutting down；
Therefore in the present embodiment, environment temperature is combined with the service condition of compressor, to control the work of the electric auxiliary heating apparatus 40；
So as 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 preparatory 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 more than or equal to first preset temperature, and less than or equal to the second preset temperature
When, whether judge compressor is first upper electricity；
When compressor is first upper electricity, the electric auxiliary heating apparatus 40 of control are opened.
In the present embodiment, when environment temperature is in the temperature range that the first preset temperature and the second preset temperature are limited
When, by the upper electric number of times for combining compressor；To control the working condition of electric auxiliary heating apparatus 40.The present embodiment is allowed for when compression
When machine is first powered on, its internal lubricating oil was not preheated in advance；And when the temperature of lubricating oil is higher, be beneficial to
The normal startup of compressor；Therefore setting is when the compressor is being first powered on, and environment temperature is in the first preset temperature
When in the temperature range limited with the second preset temperature, that is, electric auxiliary heating apparatus 40 are controlled to open.
Further, it is described when the environment temperature be more than or equal to first preset temperature, and be less than or
Whether during equal to the second preset temperature, it is also to include after the step of electricity on first to judge compressor：
When compressor is second or repeatedly upper electricity, the shutdown duration of the compressor is obtained；
Compare the shutdown duration and the second preset duration；
When the shutdown duration is more than second preset duration, electric auxiliary heating apparatus 40 are opened；
When the shutdown duration is less than or equal to second preset duration, returns and perform step S1.Based on above-mentioned
Embodiment understands that, when compressor starts not successfully, the electrical heating can be always maintained at heated condition, therefore in this programme,
When compressor is second or repeatedly upper electricity, its internal lubricating oil is heated.If therefore not differentiating between compressor
Upper electric number of times, can cause the electric working time of auxiliary heating apparatus 40 longer, and cause the problems such as compressor power consumption is larger.Therefore this programme
In, further using the shutdown duration of compressor as one of Consideration, when the duration that shuts down is more than the second preset duration, this
Carve, acquiescence judges temperature of the temperature of lubricating oil to be reduced to before being heated by electric auxiliary heating apparatus 40, it is therefore desirable to open electric auxiliary heat
Device 40, to be preheated again to lubricating oil；And when the duration that shuts down is less than or equal to second preset duration, now need
Return to step S1 is wanted, environment temperature is detected again, to judge whether to need to open electric auxiliary heating apparatus 40.
In the present embodiment, the setting of second preset duration needs the average temperature of the environment for considering 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 electric auxiliary heat
Temperature before device 40 is heated is suitable.
Based on above-described embodiment, when environment temperature is higher, the temperature of the lubricating oil also should be higher, therefore in compression
Before machine starts, it is not necessary to lubricating oil is preheated, you can meet compressor and normally start；The control of compressor described in this programme
Method processed also includes：When the environment temperature meets preparatory condition, the step of electric auxiliary heating apparatus 40 of control are opened includes：
Compare current environmental temperature and the second preset temperature；
When the environment temperature is more than second preset temperature, the electric auxiliary heating apparatus 40 are closed.
Here, the setting of first preset temperature, the second preset temperature needs to take the model of compressor, lubrication into consideration
The species of refrigerant is set in the species and heat pump of oil.
When compressor is stopped, it is necessary to detect the oil temperature of lubricating oil, to judge whether to need the oil temperature to lubricating oil
Preheated, in order to the startup next time of compressor.Therefore in this programme, the control method of described compressor, in step
Also include after rapid S4：
Whether detection compressor is stopped；
When compressor is stopped, the oil temperature of the lubricating oil in detection compressor detects the shell temperature of compressor；
Judge whether the oil temperature of the lubricating oil and the difference of environment temperature are less than or equal to the first fiducial temperature；
If so, return to 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 this programme, when the difference of oil temperature and environment temperature is less than or equal to the first fiducial temperature, oil temperature has been represented
Drop to close to environment temperature, it is therefore desirable to return to step S1, environment temperature is detected again, to determine whether that satisfaction is opened
Open the condition of electric auxiliary heating apparatus 40.And when the difference of oil temperature and environment temperature is more than the first fiducial temperature, represent the oil of lubricating oil
Temperature is also higher, it is not necessary to open electric auxiliary heating apparatus 40 and lubricating oil is heated.Therefore the present embodiment is by judging Lubricating Oil Temperature
With the difference situation of environment temperature, to determine whether to meet the condition for being again turned on electric auxiliary heating apparatus 40, it efficiently avoid to profit
Lubricating oil carries out the situation of invalid preheating, and then reduces the power consumption of compressor.
In another embodiment, it is contemplated that the oil temperature of lubricating oil is not easy to detection, therefore by detecting compressor case
Temperature is with the oil temperature of indirect reaction lubricant in compressor.
Because the shell temperature of compressor and the oil temperature of lubricating oil have a difference, therefore 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 preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
Under the inventive concept of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/use indirectly
