Description
Technical field
The present invention relates to field of air conditioning more particularly to a kind of air-conditionings and its control method of having electronic expansion valve.
Background technique
When operation of air conditioner, the shutdown of normal operation and the shutdown of mal-operation are had, it is especially right for normally shutting down
In fixed frequency air conditioner, just shut down when reaching set temperature compressor, the high-low pressure pressure difference previously set up will fade away.When again
New pressure balance is established when secondary starting again, which must need to consume certain energy, if it is possible to preferably keep
High-low pressure pressure difference before shutdown, and at the time of be maintained to when air-conditioning is again started up, certain energy will necessarily be saved.It is right
It will also result in air-conditioning disorderly closedown when such as unexpected power down, tripping, overload, load are too low in improper shutdown.
As Authorization Notice No. provides a kind of air-conditioning pressure maintaining activation system and its control for the Chinese patent of CN103398516B
Method processed, which records the pressure value before compressor of air conditioner is shut down or temperature value and downtime, and passes through on-off machine simultaneously
Refrigerant circulation is truncated in structure, after compressor is again started up, passes through starting front and back pressure value or the comparison combination downtime of temperature value
The on-off mode of on off mechanism is judged to accomplish that pressure maintaining starts, and plays energy-efficient effect.
For another example Authorization Notice No. provides a kind of fine adjustment electric expansion valve for the Chinese patent of CN102901293B
Air conditioner and its control method are respectively set 2 in the entrance and medium position of the outlet of evaporator and medium position or condenser
A temperature sensor；The temperature sampling period of temperature sensor is 0.1-1 seconds, and central processing unit is according to evaporator or condenser
The temperature gap of upper 2 temperature sensors, calculates the degree of superheat or degree of supercooling and rate temperature change and direction, works as Indoor Temperature
When spending the temperature of sensor detection close to set temperature, central processing unit is according to calculated result to the open degree of electric expansion valve
Control is adjusted in advance, controls the degree of superheat or degree of supercooling is 0-2 DEG C.The air-conditioning system under compressor identical frequency may be implemented
The increase of ability, to reach energy conservation 10% and make operation of air conditioner within the temperature range of comfort.
