It is understood that being recycled according to cooling and warming, refrigerant (gas-liquid) is flow backwards in system in order to prevent, is divided into gas
Body shut-off valve and liquid stop valve, gas stop valve is a little bigger (commonly referred to as big valve), because the density of gas is low, liquid stop valve
Caliber is smaller (commonly referred to as small valve)；Wherein, big valve trachea (extra heavy pipe), small valve adapter (liquid pipe).
The present embodiment judges the whether small valve of air-conditioning not to detect by directly detecting pressure in connecting tube and room temperature
Open or coolant leakage/not plus, the test method is simple, the states such as the simulation small valve of air-conditioning do not open, unit aneroid, to realize anti-
Mistake, this method are suitable for the air-conditioning of any specification, have reliability, are suitable for promoting.
Embodiment 3
In conjunction with Fig. 3, the present embodiment the difference from embodiment 1 is that, the present embodiment is air-conditioning work at present mould in step S1
Formula is air conditioner intelligent test method when air-conditioning heating is run, and is specifically comprised the following steps：
S21, acquisition air-conditioning current operation mode be heating operation, in the second preset time t2It is interior, obtain second temperature
Parameter T2, second pressure parameter P2。
Specifically, so that air-conditioning is in heating operation mode during operation of air conditioner, the main program of air-conditioning system can be certainly
Dynamic to call heating test function module, operator issues test letter to air-conditioning system by the button on air conditioning system controller
Number, then it heats test module and starts automatic running.In defined second preset time t 2, air-conditioning is detected by pressure sensor
System running pressure obtains second pressure parameter P2, and the connection extra heavy pipe of machine and outdoor unit is (i.e. indoors for pressure sensor setting
Tracheae) on, the real-time pressure value in tracheae can be detected automatically；The is obtained by the temperature sensor on setting indoor unit simultaneously
Two temperature parameter T2, the temperature sensor can detect indoor real time temperature automatically.
Second preset time t in the present embodiment2For 25s, the second preset time t2Runing time is too long to will affect detection effect
Rate will affect failure recall rate if less than 25 seconds.
S22, the second temperature parameter T is obtained2Corresponding second saturation pressure P2 is full, will be under air-conditioning heating operating status
The pressure limit that air-conditioning operates normally is preset as second pressure steady-state range P2 is steady。
The second temperature parameter T that will acquire2It is mapped as the saturation temperature parameter of refrigerant, and refrigerant object according to the pre-stored data
Property table, obtains the corresponding second saturation pressure P of saturation temperature of the mapping2 is full.Wherein, second pressure steady-state range P2 is steadyFor work
Personnel are configured based on experience value, can also carry out testing determining setting to air-conditioning.Second pressure stable state in the present embodiment
Range P2 is steadyCritical value be P2 is full* the second preset value, the second preset value is the statistics based on operator to air conditioner comprehensive, one
In a operation air-conditioner set room, state is not quite identical between each air-conditioner set, is by critical value setting based on practical experience
P2 is fullThe strong operability of * the second preset value, wherein the range of the second preset value is 1.03-1.07, and the present embodiment is preferably 1.05.
S23, test module judge second pressure parameter P1Whether second pressure steady-state range P is fallen into2 is steadyIt is interior；It specifically includes：
If P2≥P2 is full* the second preset value, then second pressure parameter P2Fall into second pressure steady-state range P2 is steady, operation of air conditioner
Normally；
If P2< P2 is full* the second preset value, then second pressure parameter P2Second pressure steady-state range P is not fallen within2 is steady, air-conditioning
Operation is broken down, and error protection is carried out；Above-mentioned failure be can be that the big valve of air-conditioning is not turned on, failure can be fed back at this time
Air conditioning system controller, feedback signal is sent to outdoor machine of air-conditioner by controller, and is shown by outer machine, empty after display
Tune is automatically stopped operation.
For air-conditioning under heating operation state, refrigerant enters standard indoor unit through excessive valve, at this time air-conditioning system pressure can on
Rise, can generally be raised to 2 times or so of saturation pressure, as long as therefore the second pressure parameter that obtains can sentence slightly larger than saturation pressure
It is normal to determine operation of air conditioner.
If the big valve of air-conditioning is in close state, refrigerant cannot enter standard indoor unit by big valve, although compressor of air conditioner
Still do not stop to pressurize, but the pressure sensor being located on extra heavy pipe will not be changed than the second pressure detected, can be sentenced at this time
Determine operation of air conditioner exception, stoppage protection should be carried out.
The present embodiment to detect judges whether the big valve of air-conditioning by directly detecting pressure in connection extra heavy pipe and room temperature
It does not open, the big valve of simulation system is in close state, to realize mistake proofing, suitable for the air-conditioning of any specification, improves detection effect
Rate and accuracy in detection.
