Within enclosing.
As shown in Figure 1, it is a kind of detection air-conditioner coolant leakage method, be suitable for air conditioner, the present embodiment one include with
Lower step:
S1: the currently running mode of air conditioner is obtained, and whether the compressor operating time for detecting the air conditioner reaches
Preset time;In starting of air conditioner operation, the current operational mode of air conditioner is first obtained, the operational mode of air conditioner includes system
Cold, heating or dehumidifying basic model, meanwhile, the operating condition of air-conditioning is obtained, according to the mode and operating condition of operation of air conditioner
Present mode of operation setting leaving air temp Tcm (such as table 1) is transferred, to spare in next step;The runing time for detecting compressor, works as fortune
The row time reaches preset time, illustrates that compressor is stable, and can perform the next step operation.
S2: if meeting condition, temperature of outlet air of air conditioner Tc is detected, according to the leaving air temp Tc and present mode of operation of detection
Setting leaving air temp Tcm is compared, and judges whether the absolute value of the difference of the two temperatures is greater than or equal to predetermined value;Air-conditioning is being worked as
Tc-Tcm > 5 DEG C under the mode of preceding operation illustrate that the current leaving air temp of air-conditioning and present mode of operation setting leaving air temp Tcm are inclined
Difference is larger, is unable to satisfy the use needs of user;Otherwise air-conditioning illustrates air-conditioning under currently running mode when Tc-Tcm < 5 DEG C
Current leaving air temp and present mode of operation setting leaving air temp Tcm deviation are smaller, can satisfy the needs that user uses.
S3: if meeting condition, determine air conditioner lacks refrigerant, issue alerting signal, the alerting signal be display signal or
Voice signal reminds user's air conditioner to break down and is unable to satisfy normal operation needs, please contact manufacturer and further repair;If
The fault-signal of scarce refrigerant is issued air conditioner manufacturer by the specific internet function of air-conditioning, air-conditioning, contacts user by air conditioner manufacturer, and send
Maintenance personal, which follows up, to repair.
For example, in one embodiment of the present of invention, present mode of operation sets leaving air temp Tcm table can be such as table
Shown in 1:
Table 1
As shown in table 1,1 air conditioner of certain money often uses operating condition theory leaving air temp (i.e. setting leaving air temp Tcm).
Main program will test whether compressor starts after air conditioner booting, if compressor is inactive, continue to test, such as
Fruit compressor has been turned on, and determines whether compressor has run full 5min (preset time, adjustable) and continued to test fortune if less than
The row time detects the practical leaving air temp Tc of air conditioner (it is assumed that 30 DEG C) at this time if expired, the current operation item of main program inquiry
The theoretical leaving air temp Tcm of part (outdoor environment 5/4,25 degree of set temperature, high wind heating) is 38 DEG C, and (specific air conditioner needs to have
Body passes through experiment or theoretical calculation), practical leaving air temp and theoretical leaving air temp absolute difference are 8 DEG C, are greater than 5 DEG C of threshold values
(preset threshold, adjustable) then determines that coolant leakage has occurred for air conditioner;If practical leaving air temp Tc is 37 DEG C, practical outlet air
Temperature and theoretical leaving air temp absolute difference are 1 DEG C, are less than 5 DEG C of threshold values (preset threshold, adjustable), are then determining air conditioner just
Often, practical leaving air temp is continued to test.
Detection method of the invention is by detection temperature of outlet air of air conditioner Tc, according to the leaving air temp Tc of detection and current fortune
Row mode setting leaving air temp Tcm is compared, and judges whether the absolute value of the difference of the two temperatures is greater than or equal to predetermined value, empty
Tc-Tcm > 5 DEG C under currently running mode are adjusted, determine that air-conditioning status there are problems that leaking refrigerant, meanwhile, air conditioner issues
Scarce refrigerant prompting message accordingly, to solve, conventional domestic air conditioner cannot detect secondary refrigerant leakage automatically or refrigerant lacks
Problem, it is economical and practical, easy to operate accurate to have the characteristics that.
Specifically, the preset time is 2min to 6min, general air-conditioning in normal conditions, when compressor operation is default
Between reach stable, operation can be performed the next step.
Specifically, it is that air conditioner setting is relatively reasonable that the predetermined value, which is 5 DEG C, and general air-conditioning in normal conditions, detects
Leaving air temp Tc and present mode of operation setting leaving air temp Tcm deviation it is larger, illustrate air-conditioning occur lack refrigerant failure.
A kind of method of detection air-conditioner coolant leakage as shown in Figure 1:, is suitable for air conditioner, include under the present embodiment with
Lower step:
S1: the currently running mode of air conditioner is obtained, and whether the compressor operating time for detecting the air conditioner reaches

Cold, heating or dehumidifying basic model.
S2: if meeting condition, temperature of outlet air of air conditioner Tc is detected, according to the leaving air temp Tc and present mode of operation of detection
Setting leaving air temp Tcm is compared, and judges whether the absolute value of the difference of the two temperatures is greater than or equal to predetermined value;When meeting item
Part obtains the current operating condition of air-conditioning, transfers present mode of operation according to the mode of operation of air conditioner and operating condition and set out
Air temperature Tcm (such as table 1), for judge air-conditioning under currently running mode whether Tc-Tcm > 5 DEG C, current leaving air temp with
Present mode of operation setting leaving air temp Tcm deviation is larger, illustrates that air-conditioning is unable to satisfy the use needs of user;Otherwise current fortune
Under capable mode when Tc-Tcm < 5 DEG C, illustrate the current leaving air temp of air-conditioning and present mode of operation setting leaving air temp Tcm deviation
It is smaller, it can satisfy the needs that user uses.
S3: if meeting condition, determine air conditioner lacks refrigerant, issue alerting signal, the alerting signal be display signal or
Voice signal reminds user's air conditioner to break down and is unable to satisfy normal operation needs, please contact manufacturer and further repair;If
The fault-signal of scarce refrigerant is issued air conditioner manufacturer by the specific internet function of air-conditioning, air-conditioning, contacts user by air conditioner manufacturer, and send
Maintenance personal, which follows up, to repair.
