Show failure code or the flicker of failure icon, to prompt user to overhaul.As a result, by repeatedly judging to avoid automatically controlled miss
Sentence.
Be described in detail the utility model embodiment with reference to a specific embodiment prevents control device 100 on fire
Operation principle.
By taking fixed frequency air conditioner system such as two Split type air conditioners of fixed frequency as an example, complete machine electric current I when air conditioner normal operation
For 8A, it is assumed that connection terminal module 1 is used in coastal area, so that terminals is aoxidized due to carrying salt in the air of coastal area
The case where, resistance R is 0.5 Ω at oxidation, thus when compressor start after, heating power is P=I*I*R=at connecting terminal 11
8A*8A*0.5 Ω=32W (heating power is 32 watts i.e. at connecting terminal 11), and the currently used environment of air conditioner is 30 DEG C, phase
Ying Di, temperature detect switch (TDS) 2 trigger break-off signal and are preset as 65 DEG C, are attracted temperature and are preset as 53 DEG C.

Temperature detect switch (TDS) 2 is that room temperature is connected such as 30 DEG C at this time, and indoor unit control panel 3 controls relay 41 by compressor control end 31 and inhales
It closes, and then power supply is made to be transported to compressor M1, compressor M1 operations, indoor unit control panel 3 passes through current detecting list at this time
First 5 (i.e. current transformers 51) detect that electric current is 8A, and it is normal that indoor unit control panel 3 judges that compressor M1 starts.
If increased from 32 DEG C by heating power 32W fevers, temperature detect switch (TDS) 2 at connecting terminal 11 after compressor M1 is attracted
To 65 DEG C of break-off signal of triggering, the disconnection of temperature detect switch (TDS) 2, makes 41 dead electricity of relay, to make compressor M1 dead electricity at this time.Room at this time
Interior machine control panel 3 detects that electric current becomes 0.5A from 8A by current transformer 51, can determine that temperature detect switch (TDS) 2 overheats stop jumping, and
Continuing in the first preset time, after confirming electric current still less than predetermined current, indoor unit control panel 3 controls compressor control end 31
Signal compressor is shut down in output.
After such as 30 seconds 2 minutes a period of time, temperature detect switch (TDS) 2 and connecting terminal 11 can drop to 53 DEG C from 65 DEG C, temperature
Control switch 2 becomes attracting state from off-state, and indoor unit control panel 3 is attracted such as 3 points of the second preset time in temperature detect switch (TDS) 2
It is exported by compressor control end 31 after clock and opens signal compressor, relay 41 is attracted again, and compressor M1, which is powered, to be run, electricity
Stream detection unit 5 detects that electric current is 8A.However, due to having contact resistance (i.e. heating power 32W), temperature control at connecting terminal 11
Switch 2 rises to 65 DEG C of break-off signal again, and dead electricity is out of service again by compressor M1 as previously described, at this time current detecting unit 5
Detect that electric current is 0.5A, indoor unit control panel 3 can determine whether to act for temperature detect switch (TDS) 2, and it is defeated to shut down compressor control port 31
Go out.
Since the overheat stop jumping of the temperature detect switch (TDS) 2 in continuous 2 connection terminal modules 1 has occurred, can determine that as terminals
Sub 11 contact resistances are excessive, and indoor unit control panel 3 controls air-conditioning system shutdown to enter guard mode of shutting down, and passes through display
The output of unit 6 shows failure code such as " P6 ", to remind user to overhaul air conditioner.
To sum up, the air-conditioning system proposed according to the utility model embodiment prevents control device on fire, is arranged in terminals
