As shown in figure 3, the step of a kind of control method of air-conditioner, control method is as follows：
Step S1：Detect whether the air-conditioner reaches the default not run time of air-conditioner, detection and the indoor ring of judgement
Whether border temperature T1 is less than or equal to preset temperature；
Step S2：If meeting condition, the control air-conditioner of the controller 100 opens refrigerant recovering pattern.
A kind of air-conditioner control method of the invention, by detecting the default not run time of air-conditioner and detection and judging
Whether indoor environment temperature T1 meets estimated condition, and when the condition is satisfied, control air-conditioner operation refrigerant recovering pattern makes cold
Matchmaker is all rested in outdoor unit, reduces connector or other welding position micro- leakage of the refrigerant in air-conditioner, improves air-conditioner
Service life.
Specifically, the default not run time of the air-conditioner is 10 to 20 days.The present invention is tired by computing module 101
Count air-conditioner available machine time, when air-conditioner in be not powered within 10 to 20 days when, it is considered herein that reached using the head of a household
Time does not use the situation of air-conditioning, when the situation is met, it is also possible to which user goes on business or other situations do not use air-conditioning
Device, whether during in order to more accurately confirm air-conditioner in the situation that can close refrigerant, the present invention also increases the following example
Temperature judges.
Specifically, the preset temperature is 10 DEG C to 25 DEG C.The present invention is detected and judged by detecting control module 102
Indoor environment temperature T1, determines whether that user's indoor environment temperature is comfortable, and without device of turning on the aircondition, and the environment temperature should
That continue for a rapid lapse of time, therefore, it can by the refrigerant recovering in air-conditioner to outdoor unit with the high pressure valve 1 and described
Low pressure valve 3 is isolated, it is to avoid refrigerant micro- leakage at the high pressure valve 1 and the low pressure valve 3, improves the service life of air-conditioner.
Specifically, the refrigerant recovering pattern：Open compressor and outer blower fan, the control four-way valve of the controller 100
It is refrigeration operational state, after operation 3 minutes, controls the first refrigerant on-off valve 2 to close, after operation 30 seconds, controls described the
Two refrigerant on-off valves 4 are closed, and refrigerant is locked in outdoor unit.The refrigerant recovering pattern is carried out under refrigeration operational state, operation 3
Minute, at this moment refrigerant flows to indoor set, closes the cut-out refrigerant of the first refrigerant on-off valve 2 and again flows into indoor set, reruns 30 seconds
The refrigerant of indoor set is flowed back into outdoor unit again, close the second refrigerant on-off valve 4 by refrigerant pin in outdoor unit with the high pressure
Valve 1 and the low pressure valve 3 are isolated, it is to avoid refrigerant micro- leakage at the high pressure valve 1 and the low pressure valve 3, improve making for air-conditioner
Use the life-span.
Specifically, including step S3:After the operation signal that if controller 100 receives refrigeration, dehumidifies, heat, institute
Stating controller 100 controls the first refrigerant on-off valve 2 and the second refrigerant on-off valve 4 to open, and the compressor is after 2 minutes
Open.After air-conditioner has been carried out refrigerant recovering pattern, when being received again by the operation signal of user, the first handle of controller 100
The first refrigerant on-off valve 2 and the second refrigerant on-off valve 4 are opened, and recover the path of air-conditioning system, and pressure is opened after 2 minutes
Contracting machine, reduces the pressure of the path of air-conditioning system.
In embodiments of the invention one, refrigeration mode is not started within continuous 15 days when air-conditioner, computing module 101 has added up
Meet the number of days not started, then detect indoor environment temperature T1, when T1 temperature≤25 DEG C (or other default temperature), recognize
For current weather comes into autumn.Now, compressor and outer blower fan are opened, four-way valve is refrigeration operational state, runs 3 points
Zhong Hou, the first refrigerant on-off valve 2 closes (if electric expansion valve, electric expansion valve is just fully closed), and after 30S, the second refrigerant leads to
Disconnected valve 4 is closed.Indoor set does not have control action.Computing module 101 resets, if when the controller 100 receive refrigeration, dehumidifying,
After the operation signal for heating, the controller 100 controls the first refrigerant on-off valve 2 and the second refrigerant on-off valve 4 dozens
Open, the compressor is opened after 2 minutes.After air-conditioner has been carried out refrigerant recovering pattern, the operation of user is received again by
During signal, controller 100 first opens the first refrigerant on-off valve 2 and the second refrigerant on-off valve 4, recovers air-conditioning system
Path, open compressor after 2 minutes, reduce the pressure of the path of air-conditioning system.
In embodiments of the invention two, refrigeration mode is not started within continuous 15 days when air-conditioner, computing module 101 has added up
Meet the number of days not started, then detect indoor environment temperature T1, when T1 temperature≤15 degree (or other default temperature), recognize
To come into spring.Compressor and outer blower fan are now opened, four-way valve is refrigeration operational state, after running 3 minutes, first is cold
Matchmaker's on-off valve 2 closes (if electric expansion valve, electric expansion valve is just fully closed), and after 30S, the second refrigerant on-off valve 4 is closed.Room
Interior machine never has control action.Computing module 101 resets, if the controller 100 receives refrigeration, the operation for dehumidifying, heating
After signal, the controller 100 controls the first refrigerant on-off valve 2 and the second refrigerant on-off valve 4 to open, the compression
Machine is opened after 2 minutes.After air-conditioner has been carried out refrigerant recovering pattern, when being received again by the operation signal of user, control
Device 100 first opens the first refrigerant on-off valve 2 and the second refrigerant on-off valve 4, recovers the path of air-conditioning system, 2 points
Compressor is opened after clock, the pressure of the path of air-conditioning system is reduced.
