Description
Technical field
The invention belongs to air conditioner controlling technology fields, specifically propose a kind of controlling party for preventing transducer air conditioning from shutting down up to temperature
Method.
Background technique
Currently, home-use air conditioner is in refrigeration or heating operations, if reaching temperature set by user, air conditioner
Meeting autostop, that is, compressor can stop working.But some energy demand of inner evaporator discharges, and needs inner blower
It continues to run, there is wind to go out so as to cause interior machine network interface, for example, interior machine air port blows out hot wind in refrigeration mode, in heating mould
Interior machine air port blowing cold air when formula makes the comfort level of user be deteriorated.Ruo Dawen is directly closed wind guide strip, interior machine evaporator after shutting down
In heat or cooling capacity cannot release well, will lead to the deformation of indoor machine plastic member, reduce the reliability of air conditioner.
In this way, frequent can greatly reduce room to the fluctuation of indoor environment temperature and the discontinuity of air conditioner sound up to temperature shutdown
Comfort；On the other hand, frequent effectively to realize energy saving up to temperature shutdown, but also can be to the compressor service life
It makes a big impact.
The present invention provides a kind of control method of air-conditioner with fixed frequency, controller and fixed frequency air conditioners by CN201510214564.X
Device, which comprises obtain current indoor temperature value and current outdoor temperature value；By the current indoor temperature value and determine frequency
The set temperature value of air conditioner is compared；When the current indoor temperature value is less than or equal to the set temperature value, root
The refrigerant stream of the air-conditioner with fixed frequency is adjusted by electric expansion valve according to the current outdoor temperature value and the set temperature value
Amount；The electric expansion valve is the connection that the direct carry out compressor return air at compressor both ends of the air-conditioner with fixed frequency is arranged in
The electric expansion valve for being used to adjust cold medium flux on pipe.The present invention can be avoided the frequent wave shut down up to temperature to room temperature
The automatic control of fixed frequency air conditioner energy conservation comfortable function is realized in the dynamic and influence to the compressor service life.
This method is directed to air-conditioner with fixed frequency, is directly compressed by the setting at the compressor both ends of the air-conditioner with fixed frequency
The connecting tube of machine return-air, and electric expansion valve is set in the connecting tube, by the aperture control for controlling the electric expansion valve
Cold medium flux processed, and then can be avoided the frequent influence shut down up to temperature to the fluctuation of room temperature and to the compressor service life,
The automatic control of fixed frequency air conditioner energy conservation comfortable function is realized to realize the comfortable function of fixed frequency air conditioner energy conservation.This method is to be directed to
Air-conditioner with fixed frequency and be arranged, and need in addition setting electric expansion valve.
CN201610825399.6 reaches warm halt control method and air conditioner suitable for air conditioner the present invention relates to a kind of.It should
Method includes: controller real-time reception from temperature sensor current indoor temperature value collected, and and set temperature value into
Row compares；When current indoor temperature value and set temperature value meet the first preset condition, controller is generated: the first compressor control
System instruction, stops working for controlling compressor；First outdoor fan control instruction, stops working for controlling outdoor fan；
Second indoor fan control instruction works under the first default indoor fan revolving speed for controlling indoor fan；With the first/the
Two wind guide strip control instructions, for controlling wind guide strip from first position to the second position or keeping the second position motionless, so that
The angle of the wind guide strip and indoor fan air outlet is that predetermined angle prevents wind to user.The air conditioner is for executing
It states up to warm halt control method.The present invention can improve users'comfort to avoid in outlet air blow-through to user's body.
Alleviated by the control to compressor, outdoor fan, indoor fan and wind guide strip in the technology up to temperature and shuts down band
The non-comfort come, but compressor can not effectively realize energy saving up to warm shutdown status still in frequent, but also
It can make a big impact to the compressor service life.
To sum up, when room temperature reaches user's set temperature, frequency changer it is defeated can to reduce cooling capacity by reducing running frequency
Out, stablize room temperature in user's set temperature.And air-conditioner with fixed frequency is because frequency is non-adjustable, when reaching user's set temperature,
Still continue the same cooling capacity of output phase, easily cause to shut down up to temperature.Room temperature rises after shutdown, and air conditioner is then turned on cooling, people
Feel sometimes hot and sometimes cold, comfort is poor.But present transducer air conditioning is because of driving, pipeline stress vibration cause, and frequency is between 1~30Hz
Most frequencies are all unable to satisfy design requirement, therefore are 30Hz by the minimum operating frequency of minimum permission when design.But when sky
The refrigerating capacity for adjusting device operation 30Hz to generate is when being still greater than room demand, especially big air-conditioning cubicle when, can still have frequency
Numerous the problem of shutting down up to temperature, fluctuate room temperature, comfort decline, and high frequent start-stop will lead to power consumption increase.
In view of this, proposing the present invention.
