Description
Technical field
The present invention relates to field of air conditioning, are especially the heat detector wrong anti-detection and selfreparing of double-compressor air-conditioning system
Control method.
Background technique
VRF Air Conditioning System is frequently necessary to an outdoor unit and drives multiple indoor units, and load is larger, so often setting
Two compressors are set, and the vent position of each compressor can be equipped with exhaust temperature of the heat detector to measure compressor
Degree.Since the air conditioning system components with double-compressor are numerous, so inevitably occurring compressing two during production and maintenance
The anti-inserted situation of the corresponding heat detector of machine.And the compressor exhaust temperature of above-mentioned heat detector measurement, it is regulation operation of air conditioner
Important parameter, once it is anti-inserted, just necessarily cause air-conditioning system running abnormal, influence user experience.
Moreover, huge just because of multi-line system, component is numerous, so the reason of unit failure is also varied
, the rotation speed of fan of such as outer machine, interior machine is insufficient, heat exchanger coil pipe blocks, heat exchanger coils show that being stained with ash makes heat exchange amount not
Foot, capillary blockage of heat exchanger coils end etc., therefore when unit operation troubles, technical staff will often take a substantial amount of time
Carried out after checking one by one with energy, could finally lock failure be due to heat detector it is anti-inserted caused by, so once occurring warm
The anti-inserted situation of sensor, technical staff difficultly innumerable trials and tribulations could must check out real reason from various faults reason,
Moreover, detection time is long, the time of reparation is delayed naturally, and very big inconvenience is also brought to user, causes poor user experience.
Summary of the invention
The technical problem to be solved by the present invention is to, provide it is a kind of can fast and accurately detect heat detector it is whether anti-inserted and
The heat detector of dislocation can be corrected to the wrong anti-detection of heat detector of the double-compressor air-conditioning system on correct compressor automatically
And selfreparing control method.
The technical solution of the invention is as follows, provides a kind of heat detector of double-compressor air-conditioning system having following structure
Wrong anti-detection and selfreparing control method, step include:
A, the control circuit with flowering structure is set up；
The control circuit include the master controller of air-conditioning, the first socket for inserting the first heat detector and for insert second temperature
Second socket of sensor, master controller are equipped with the first contact and the second contact；First socket is through the first conducting wire and the first contact
Connection, the first conducting wire are equipped with normally closed switch, and the first socket is connect through the first wire jumper with the second contact, and the first wire jumper is equipped with normal
Switch；Second socket is connect through the second conducting wire with the second contact, and the second conducting wire is equipped with normally closed switch, and the second socket is through second
Wire jumper is connect with the first contact, and the second wire jumper is equipped with normal open switch；
B, unit booting operation a minutes, then open a compressor and another compressor is closed, then are sentenced
It is disconnected, if meeting one of following two condition, determine that heat detector is anti-inserted；
Condition 1: every b minutes detection is primary, and the delivery temperature for the compressor being not keyed up increases m DEG C or more, meanwhile, booting
The delivery temperature of compressor reduce n DEG C or more；
Condition 2: the compressor shutdown time is more than c minutes, and the delivery temperature of the compressor is greater than or equal to z DEG C；
C, master controller is connected to two normal open switch and disconnects two normally closed switch.
The heat detector of double-compressor air-conditioning system of the present invention wrong anti-detection and selfreparing control method and prior art phase
Than having the advantage that
Firstly, being not necessarily to artificial detection, can fast and automatically, accurately determine whether the heat detector of two compressors is anti-inserted,
Moreover, it is once anti-inserted, the connection relationship of heat detector socket and master controller contact can be corrected through control circuit, make the biography of wrong plug
Sensor is aligned with the correct contact of master controller automatically.
Detailed description of the invention
Fig. 1 is the system knot of the heat detector wrong anti-detection and selfreparing control method of double-compressor air-conditioning system of the present invention
Structure schematic diagram.
As shown in the figure 1, master controller, the 2, first heat detector, the 3, first socket, the 4, second heat detector, the 5, second socket, 6,
First contact, the 7, second contact, the 8, first conducting wire, the 9, first wire jumper, the 10, second conducting wire, the 11, second wire jumper.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
As shown in Figure 1, the heat detector of double-compressor air-conditioning system of the present invention wrong anti-detection and selfreparing control method,
Steps are as follows.
A, the control circuit with flowering structure is set up.
The control circuit includes the master controller 1 of air-conditioning, the first socket 3 for inserting the first heat detector 2 and for inserting
Second socket 5 of two heat detectors 4, master controller 1 are equipped with the first contact 6 and the second contact 7；First socket 3 is through the first conducting wire 8
It being connect with the first contact 6, the first conducting wire 8 is equipped with normally closed switch, and the first socket 3 is connect through the first wire jumper 9 with the second contact 7,
