As shown in Fig. 2 the invention provides a kind of air conditioner, air conditioner includes indoor set and outdoor unit, wherein, outdoor unit
On be provided with the first temperature sensor for detecting outdoor environment temperature, current outdoor environment temperature can be detected in real time；
Meanwhile, outdoor unit is additionally provided with the variable conpacitance compressor component for driving refrigerant circulation, and the variable conpacitance compressor component can be with
Refrigerant in air-conditioner coolant circulation line is compressed, and circulates offer between machine and outdoor unit indoors for refrigerant
Power.
Variable conpacitance compressor component includes variable conpacitance compressor 12, and in embodiment, variable conpacitance compressor 12 at least includes
Two compression cylinders, each compression cylinder individually can perform squeeze operation to refrigerant；Air conditioner is in different temperatures and psychrometric condition
During lower operation, it also has corresponding requirement to the refrigerant flowed in medium circulation pipeline, for example, indoor and outdoor temperature is relatively low in the winter time
When, to accelerate the heating efficiency of air conditioner, it is necessary to which compressor exports more refrigerants；Or indoor temperature is set close to user in the winter time
It is fixed when heating temperature, to improve the efficiency of air conditioner, it is necessary to which compressor is compressed with higher compression ratio to refrigerant.Cause
This, the operational mode for the variable conpacitance compressor 12 that the present invention is used includes Bi-level mode and twin-tub pattern, wherein, in varying capacity pressure
When contracting machine 12 is run with Bi-level mode, the refrigerant for flowing through variable conpacitance compressor 12 is compressed successively by each compression cylinder, warp
The refrigerant for crossing multi-stage compression is exported to medium circulation pipeline, can improve the compression ratio of refrigerant, therefore Bi-level mode is applied to temperature
The less situation of the poor smaller or humidity difference of degree；And when variable conpacitance compressor 12 is with twin-tub mode operation, flow through varying capacity pressure
The refrigerant of contracting machine 12 is individually compressed by each compression cylinder, is not circulated mutually between the refrigerant of each compression cylinder compression, often
One compression cylinder is completed after compression, and the refrigerant individually compressed it is exported to medium circulation pipeline, compared to Two-stage Compression
Multiple compression cylinders under pattern, twin-tub pattern perform squeeze operation simultaneously, can export the refrigerant of more multiple numbers, therefore
Suitable for the situation that temperature difference is larger or humidity difference is larger, refrigerant demand is more.
Due to the polytropy of indoor and outdoors environmental factor, residing operating mode can also have differences during operation of air conditioner, for example,
In the winter time in severe cold weather situation, outdoor environment temperature is relatively low, directly influences the heat exchanger of outdoor unit and changing for outdoor environment
Heat；Or, in daytime and two periods in evening in the winter time, outdoor environment temperature is changed greatly, therefore conventional air-conditioning
When the compressor of device is run with single-mode, it is impossible to meet the refrigerant demand under current working.Therefore, using variable conpacitance compressor
12 air conditioner of the invention, to be applicable the refrigerant demand under different operating modes, in embodiments of the invention, such as Fig. 2 institutes
Show, by taking winter heating's operating mode as an example, present invention also offers a kind of control method of air conditioner, control method at least includes following
Step：S101, control air conditioner heat-production operation；S102, it is less than or equal in the outdoor environment temperature acquired in temperature sensor
During the first temperature threshold, variable conpacitance compressor is controlled with twin-tub mode operation, wherein, twin-tub pattern includes variable conpacitance compressor
The operational mode of two independent compression refrigerants of compression cylinder.
The controller of air conditioner of the present invention can control variable conpacitance compressor 12 to carry out double according to different outdoor environment temperatures
Cylinder compresses the switching with Two-stage Compression isotype, can meet specified heating capacity and efficiency requirement, can meet under low temperature and make greatly again
Heat needs.
In the above-described embodiments, air conditioner runs heating mode, sequence of flow of the refrigerant in medium circulation pipeline in the winter time
For：11 → variable conpacitance compressor of outdoor heat exchanger of 21 → outdoor unit of indoor heat exchanger of variable conpacitance compressor component → indoor set
Component, wherein, refrigerant absorbs heat in the outdoor heat exchanger 11 for flowing through outdoor unit from outdoor environment, is changed in the interior for flowing through indoor set
Hot device 21 is to indoor environment heat release, so as to reach the purpose that heating is heated to indoor environment.
In the winter time in heating condition, detected in real time by the first temperature sensor for being arranged at outdoor unit in outdoor environment temperature
Obtain, the first temperature sensor will detect that the parameters such as obtained outdoor environment temperature are transmitted to controller, in order to controller pair
The switching adjustment of the operational mode of variable conpacitance compressor 12；In addition, the above-mentioned control that controller is performed under heating condition in the winter time
The number of times of flow is one or many, therefore when controller performs the above-mentioned control flow of n-th, and the first temperature sensor can be with
The real-time outdoor environment temperature corresponding with current n times control flow is transmitted to air conditioner, is easy to controller in n-th control
During flow, the pattern of variable conpacitance compressor 12 switched to N-1 secondary control flows carries out accommodation, so that air-conditioning exists
In running in longer period, the operational mode of variable conpacitance compressor 12 can be worked as with different time points or period
Preceding operating mode is adapted.
In step s 102, the first temperature threshold is the threshold parameter being stored in advance in controller, for example, in controller
Storage the first temperature threshold can be 2 DEG C, 3 DEG C, 5 DEG C etc., i.e. the first temperature threshold be winter temperature it is relatively low, may shadow
Ring the temperature parameter that outdoor heat exchanger 11 and outdoor environment exchange heat, therefore using the first temperature threshold as judging variable conpacitance compressor
The critical condition of 12 operational mode.
Meanwhile, in step s 102, when outdoor environment temperature is less than or equal to the first temperature threshold, it can determine whether outdoor low
Warm condition can limit the heat exchange amount of outdoor heat exchanger 11, therefore variable conpacitance compressor 12 needs to transport with the pattern for exporting more refrigerants
OK.For example, the first temperature threshold that air conditioner is set is 3 DEG C, air conditioner is after start heating operation, the first temperature sensor institute
Detect that obtained outdoor environment temperature is 1 DEG C, then meet above-mentioned outdoor environment temperature sentencing less than or equal to the first temperature threshold
Broken strip part, controller controls variable conpacitance compressor 12 with twin-tub mode operation, the execution refrigerant compression of two compression cylinder independence
Operation, and to the coolant quantity of the twice single compressed cylinder body of medium circulation pipeline output, outdoor heat exchanger 11 is flowed through so as to increase
Coolant quantity, improve the heat exchange amount of air conditioner and outdoor environment.
In an embodiment of the present invention, the control flow of control method also includes step S103, big in outdoor environment temperature
When second temperature threshold value, control variable conpacitance compressor is run with Bi-level mode, and second temperature threshold value is more than the first temperature
Threshold value is spent, wherein, the operational mode of two compression cylinders of Bi-level mode including variable conpacitance compressor compression refrigerant successively.
In step s 103, second temperature threshold value is similarly the threshold parameter being stored in advance in controller, for example, control
The second temperature threshold value of device memory storage can be 5 DEG C, 7 DEG C etc., i.e. the first temperature threshold be winter temperature it is moderate, not to outdoor
The heat exchange of heat exchanger 11 and outdoor environment causes larger temperature parameter, therefore second temperature threshold value also served as to judge varying capacity pressure
Another critical condition of the operational mode of contracting machine 12.
In different air conditioner types, its controller is stored with one or more first temperature thresholds and second temperature threshold
The threshold value combination that value is constituted, for example, threshold value combines 1 (the first 2 DEG C of temperature threshold, 5 DEG C of second temperature threshold value), threshold value combination 2
(first 3 DEG C of temperature threshold, 7 DEG C of second temperature threshold value), etc..In each threshold value combination, second temperature threshold value is all higher than first
Temperature threshold, it is identical with second temperature threshold value to avoid the occurrence of the first temperature threshold, lead to not judge that varying capacity compresses
The problem of follow-up operation pattern of machine 12.
In an embodiment of the present invention, air conditioner also includes the second temperature sensor for being used to detect indoor environment temperature,
Second temperature sensor may be disposed at the air inlet of indoor set, so that the indoor environment temperature parameter that its detection is obtained is with working as
Preceding indoor environment temperature is close or identical.
Meanwhile, also include the step of control method：S104, in outdoor temperature it is more than the first temperature threshold and less than second
During temperature threshold, initial target timing duration is determined；Determine that the difference that initial target timing duration subtracts prefixed time interval is mesh
Mark timing duration；When timer reaches target timing duration, the target for obtaining user's setting heats temperature；S105, determine mesh
Mark heats the temperature approach that temperature subtracts the indoor environment temperature that second temperature sensor is detected；S106, in temperature approach it is more than or waits
When preset temperature difference threshold, control variable conpacitance compressor is with twin-tub mode operation.
In step S104, when judging whether outdoor temperature is more than the first temperature threshold and is less than second temperature threshold value, the
One temperature threshold and second temperature threshold value are the threshold parameter in the same threshold value combination in previous embodiment, for example, controller
Internal memory contains threshold value combination 1 and threshold value combination 2 in previous embodiment, the outdoor environment temperature that the detection of the first temperature sensor is obtained
Spend for Tao, then during controller performs step S104 each time, outdoor environment temperature Tao can only be combined with threshold value 1 and
The threshold parameter of one of which in threshold value combination 2 is compared, when above-mentioned control flow is performed a plurality of times in controller, to improve
The accuracy of control process, typically in step S104, is combined using same group of threshold value.
In step S104, during air-conditioning start operation, when the outdoor environment temperature of acquisition is more than the first temperature threshold and is less than
During second temperature threshold value, the pattern of the variable conpacitance compressor 12 when the acquiescence of variable conpacitance compressor 12 is former air conditioner operation
Operation.
Meanwhile, initial target timing duration is determined, determines that the difference that initial target timing duration subtracts prefixed time interval is
Target timing duration, prefixed time interval can be performed according to the setting time interval for being stored in advance in controller, for example, setting
Air conditioner repeats the indoor environment temperature obtained and the target that sets of user heat the order of temperature as 1,2,3 ..., n, air-conditioning
The target that acquisition user sets during start operation heats the order of temperature as 1, and default time interval is set as 5min, then is holding
During row order 2, a length of 30min during initial target timing, then a length of 25min during target timing, i.e., the step of execution order 1
After S105 and step S106, if the variable conpacitance compressor of air conditioner is unsatisfactory for the condition of twin-tub mode operation, after 25min
Execution order 2, and repeat step S105 and S106；If meeting the variable conpacitance compressor of air conditioner with the bar of twin-tub mode operation
Part, then need not continue executing with follow-up order 2,3 ..., n correlation step.Similarly, still it is unsatisfactory for air conditioner in execution order 2
Variable conpacitance compressor with the condition of twin-tub mode operation when, then in the step S104 of order 3 determined by initial target timing
A length of 25min during the initial target timing of the target timing duration, i.e. order 3 of Shi Changwei order 2, calculates the target timing determined
Duration is then 20min, and the rest may be inferred.
In step S105, for ease of the numeric ratio in follow-up judgment step compared with target heats temperature and indoor environment temperature
Temperature approach between degree typically takes its absolute value.
In step s 106, temperature difference threshold is similarly the threshold parameter being stored in advance in controller, for example, in controller
The temperature difference threshold of storage can be 2 DEG C, 3 DEG C, 4 DEG C etc..
The temperature approach that target is heated between temperature and indoor environment temperature is bigger, then indoor environment temperature heats temperature with target
Temperature difference between degree is bigger, thus in step s 107, when temperature approach is more than or equal to preset temperature difference threshold, control
Variable conpacitance compressor 12 is with twin-tub mode operation, the execution refrigerant squeeze operation of two compression cylinder independence, and to refrigerant circulation
Pipeline exports the coolant quantity of twice single compressed cylinder body, so as to increase the coolant quantity for flowing through outdoor heat exchanger 11, improves air-conditioning
The heat exchange amount of device and outdoor environment, accelerates air conditioner and heats heating process to indoor environment.
Also include in the above embodiment of the present invention, the step of control flow performed by controller：S107, in the temperature difference
When value is less than preset temperature difference threshold, control variable conpacitance compressor is run with Bi-level mode, wherein, Bi-level mode includes varying capacity
The operational mode of two compression cylinders of compressor compression refrigerant successively.Target heats the temperature between temperature and indoor environment temperature
Difference is smaller, then the temperature difference that indoor environment temperature and target are heated between temperature is smaller, therefore in step s 107, in temperature
When difference is less than preset temperature difference threshold, control variable conpacitance compressor 12 is run with Bi-level mode, and two compression cylinders are held successively
Row refrigerant squeeze operation, to improve the heat exchange efficiency of compression ratio of the air-conditioning to refrigerant, enhancing air conditioner and outdoor environment.
