Specific embodiment
In the application, the representative equipment of air conditioner is air conditioner, for the ease of being illustrated, in following the description
In, it is described in detail by control process of the air conditioner to air conditioner；It, can be air conditioner and air conditioner in described below
It is considered as equivalent；Those skilled in the art are when understanding the application, it is not possible to merely due to literal difference, and by air-conditioning
Device and air conditioner are considered two mutually different restrictions.
In the application, the operational mode of usual air-conditioning includes: refrigeration mode, heating mode, ventilation mode, dehumidification mode etc.
Mode.Single cylinder operation mode, twin-tub operation mode, single cylinder increasing enthalpy operation mode, twin-tub increasing enthalpy operation mode are the operation of air-conditioning
Mode.
It is explained for the ease of the operation mode to air-conditioning, we are with earlier patent application: a kind of air-conditioning tonifying Qi
Increasing enthalpy method, system and air-conditioning (application number: are explained based on 201510416281.3).Wherein, air-conditioning passes through benefit
The mode of gas achievees the effect that increasing enthalpy, on this basis, in order to increase the ability to work of compressor, can set compressor to
There are two the compressors of compression cylinder (being also possible to multiple) for tool, in this way, being single cylinder in the case where single compression cylinder is only used only
Operation mode is twin-tub operation mode using two compression cylinders or multiple compression cylinders, in fact, can also be with
On the basis of single cylinder operation mode and twin-tub operation mode, increase multiple operation modes, to correspond to using multiple compression cylinders
Situation.
Single compression cylinder is only used only in single cylinder operation mode therein as a result, as compressor, and does not carry out to air conditioner
Increasing enthalpy；Twin-tub operation mode, as compressor use two or more compression cylinders, but do not carry out increasing enthalpy to air conditioner；Single cylinder increases
Single compression cylinder is only used only in enthalpy operation mode, as compressor, but carries out increasing enthalpy to air conditioner；Twin-tub increasing enthalpy operates mould
Formula, as compressor use two or more compression cylinders, and carry out increasing enthalpy to air conditioner.
In order to realize the more accurate control to compressor, it is necessary to first be carried out to the variation of the working condition of compressor clear
The understanding of Chu.In normal working condition, compressor can adjust the running frequency of itself according to the actual demand of air conditioner
(being the actual motion frequency that external controller controls compressor by control signal during actual adjustment), if air-conditioning
The refrigerating capacity or heating capacity that device needs are higher, and compressor can improve the running frequency of itself, to meet the needs of air conditioner；If
The refrigerating capacity or heating capacity that air conditioner needs are lower, and compressor can reduce itself in the case where meeting the needs of air conditioner
Running frequency.
On this basis, we are further illustrated the transfiguration of compressor.In order to make it easy to understand, we are by way of example
The mode of son is illustrated situation.It is emphasized that.Specific number in the example shown, merely to show size relation,
The not exact value of actual working state.It is exemplified below:
Under the normal operation of air conditioner, compressor is run with a certain running frequency, can achieve 3500 watts of system
Cooling capacity.At this point, user has adjusted the target temperature of room temperature there may be a kind of situation, to reach the target temperature, need
The running frequency of compressor is wanted to be adjusted, to reach 7000 watts of refrigerating capacity；In the case, in order to reach the system of air conditioner
Cold requirement needs to carry out transfiguration to compressor.
It is of course also possible to there is another situation, if outdoor environment produces lasting high temperature, so that the refrigeration of air conditioner
Effect produces decaying, that is to say, compressor is run with the running frequency, is unable to reach 3500 watts of refrigerating capacity.Herein
In the case of, in order to reach the refrigeration requirement of air conditioner, need to carry out transfiguration increasing enthalpy to compressor.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
According to Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, it is illustrated in conjunction with remaining attached drawing.
As shown in Figure 1, its flow chart for the control method of the air condition of that present invention；Wherein, the controlling party of the air conditioner
Method, comprising:
Step 100, air conditioner runs the first preset time under single cylinder operation mode；
Air conditioner after actuation, internal various operating parameters, such as evaporator temperature, suction temperature, pressure at expulsion,
It is in extremely low level, and these parameters are in constantly variation due to refrigerating/heating demand, it can not be truly
Reaction reaches corresponding refrigerating/heating demand, so needing first to run a period of time in single cylinder operation mode, so that in air conditioner
After the operation in portion reaches stable state, then the operating parameter inside air conditioner is acquired, it so just can be to avoid air-conditioning
The measurement inaccuracy as caused by the irregular change of parameter leads to the problem of precise control deficiency after device starting.
Optionally, first preset time is 5-10min；In this way, can both to reach stable inside air conditioner
Operating status, and the accurate operating parameter inside air conditioner can be measured in time, to be carried out in time to the operation of air conditioner
Adjustment.
Step 200, the air conditioner obtains the operation of air conditioner to when operational mode is heating mode or refrigeration mode
Parameter, the operating parameter include outer ring temperature or condensation temperature or pressure at expulsion and pressure of inspiration(Pi)；
The operational mode of air-conditioning is divided into four kinds, is refrigeration mode, heating mode, ventilation mode, dehumidification mode.Wherein,
Under dehumidification mode, the running frequency of compressor in air conditioner is required very low, compressor only needs single cylinder operation that can meet and want
It asks；Under ventilation mode, starting compressor is not needed.In this way, just being needed only under the refrigeration mode of air-conditioning or heating mode
The switching of single twin-tub or increasing enthalpy is carried out according to the operating parameter of air conditioner.
In this way, by determine air-conditioning operational mode, can in order to air conditioner transfiguration and increasing enthalpy control.
Wherein, the pressure of inspiration(Pi) is the pressure of compressor air suction mouth；The condensation temperature is condenser in air conditioner
Temperature；The pressure at expulsion is the pressure of exhaust outlet of compressor；The outer ring temperature is the outdoor environment of the air conditioner
Temperature.In order to make it easy to understand, condenser is to play the dress that high-temperature gas or steam are condensed into liquid in air conditioner in the application
It sets, carries out heat release, in air conditioner refrigeration, evaporator is located in air-conditioner outdoor unit, and in air conditioner heat-production, evaporator is located at sky
It adjusts in indoor unit；Wherein, it for the ease of measurement, can as be condensed using the coil temperature of condenser as the temperature of condenser
Temperature.
The condensation temperature is the temperature of condenser, it should be noted that in the application, condenser is defined as to refrigeration
Agent is condensed to discharge the equipment of heat, therefore in cooling mode, and condenser is located inside air-conditioner outdoor unit；In heating mould
Under formula, condenser is located inside air conditioner indoor unit.
In this step, the operating parameter includes outer ring temperature or condensation temperature or pressure at expulsion and pressure of inspiration(Pi)
Power；Refer to the operating parameter include outer ring temperature and pressure of inspiration(Pi) or including condensation temperature and pressure of inspiration(Pi) or including row
Atmospheric pressure and pressure of inspiration(Pi).
Step 300, judge whether the operating parameter meets the first preset condition；
Whether the operating parameter meets the first preset condition, refers to that outer ring temperature and pressure of inspiration(Pi) meet the first default item
Part or condensation temperature and pressure of inspiration(Pi) meet the first preset condition or pressure at expulsion and pressure of inspiration(Pi) meets the first default item
Part；Its essence is meant that pressure of inspiration(Pi) meets the first preset condition, while in outer ring temperature, condensation temperature, in delivery temperature
Any one also meets the first preset condition.
When not meeting the first preset condition, show that the load of air conditioner is lower, if meeting first preset condition, table
The load of bright air conditioner is higher.
Step 400, if meeting first preset condition, the air conditioner is switched to twin-tub operation mode.
If meeting first preset condition, show that the load of air conditioner is higher；If taking single cylinder operation mode at this time,
It may then be difficult meet the needs of air conditioner, or compressor is needed just to can satisfy air conditioner with high running frequency operation
Demand (compressor is run with high running frequency, very big damage can be not only brought to compressor, but also can be generated greatly
Noise, influence the normal use of air conditioner).
In the case, the air conditioner is switched to twin-tub operation mode, compressor can be made with suitable operation
Frequency just can satisfy the demand of air conditioner when running, play the role of reducing noise and extend compressor service life, thus
The experience effect of user can be increased.
Wherein, air conditioner in the process of running, can be general to produce with the variation of external environment or the variation of user's control
Raw two kinds of problems: one, need higher refrigerating capacity or heating capacity demand, two, air conditioner attenuated inside.Obtain outer ring temperature or
The purpose of person's condensation temperature or pressure at expulsion, exactly be used to speculate in the air conditioner, produce above-mentioned any problem or
Person whether simultaneously produce two kinds of problems (the case where due to air conditioner in actual operation, is increasingly complex, be also possible to generate with
The third or the 4th kind of problem except upper two kinds of problems, therefore, outer ring temperature or condensation temperature or pressure at expulsion pair
The conclusion for obtaining a Relative Fuzzy in the supposition of air conditioner), the characteristic that different problems are shown be it is different, only
Speculated by outer ring temperature or condensation temperature or pressure at expulsion, uncertainty is very high, therefore in the application
It is combined with pressure of inspiration(Pi) and is judged, can reduce its uncertainty, increases the accuracy of judgement, so that empty
Adjust the switching of device operation mode more accurate.
When meeting any one in following condition, determine that the operating parameter meets first preset condition:
Condition one: under refrigeration mode, the pressure of inspiration(Pi) is less than or equal to first pressure threshold value and the outer ring temperature is greater than
Equal to the first circumstance temperature threshold value；
Condition two: under refrigeration mode, the pressure of inspiration(Pi) is less than or equal to first pressure threshold value and the condensation temperature is greater than
Warm threshold value solidifying equal to described first；
Condition three: under heating mode, the pressure of inspiration(Pi) is less than or equal to first pressure threshold value and the outer ring temperature is less than
Equal to the third circumstance temperature threshold value；
Condition four: under heating mode, the pressure of inspiration(Pi) is less than or equal to first pressure threshold value and the condensation temperature is greater than
Warm threshold value solidifying equal to the third；
Condition five: the ratio of the pressure at expulsion and the pressure of inspiration(Pi) is more than or equal to first row suction and compares threshold value.
