Specific embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect become more apparent, with
Lower combination drawings and Examples, are further elaborated to this utility model.It should be appreciated that concrete reality described herein
Apply example only in order to explain this utility model, be not used to limit this utility model.
Refer to Fig. 1, this utility model provides a kind of multi-split air conditioner, it includes an outer machine 1 and described outer machine 1 leads to
Cross refrigerant pipeline and connect machine in formed refrigerant circulation circuit at least two, as illustrated first in machine 22 in machine 21, second,
Machine 23 etc. in 3rd, and controller (not shown)；It is respectively equipped with a section between the high pressure lateral line of each interior machine and outer machine 1
Stream device 3, the low pressure lateral line of each interior machine is respectively arranged with an electromagnetic valve 4, each electromagnetic valve 4 is electricly connected with controller.
The multi-split air conditioner that this utility model embodiment provides can in heating operations to each in cold-producing medium in machine
Effectively adjusted, after system boot heating operation, controller detects the opening of each interior machine first, closing no to heat needs
Seek the corresponding electromagnetic valve of interior machine 4, it is to avoid when operation heats under low temperature environment, cold-producing medium migrates into the interior machine being not turned in a large number
Causing serious heat waste it is ensured that needing the interior mechanism cold ability heating, making the temperature that indoor quick regulation extremely needs, well
Solve multi-split air conditioner heating capacity not enough, heating operations coolant maldistribution, the problem of heat waste.
As this utility model provide multi-split air conditioner a kind of specific embodiment, each interior machine be additionally provided with for
The temperature inductor 5 of detection indoor temperature, for the real-time temperature obtaining in room, to control according to indoor real time temperature
The unlatching of the electromagnetic valve 4 compressing on pipeline of machine in correspondence, after interior mechanism heat reaches room design temperature condition, can pass through
The corresponding electromagnetic valve of machine 4 in controller cut out, less than the temperature conditionss setting, then the electromagnetic valve 4 opening machine in corresponding in real time continues
Continuous heated, not only avoid the temperature that air conditioning system excessively heats, also avoid ambient temperature too low simultaneously, improve one drag many
Air conditioner heat-production comfortableness.
Specifically, outer machine 1 includes compressor 11 and cross valve 12, further can also compressor 11 and cross valve 12 it
Between be additionally provided with gas-liquid separator 14, this gas-liquid separator 14 can prevent liquid refrigerants from entering in compressor 11, and only allows gaseous state
Coolant enters in compressor 11, prevents compressor 11 from producing liquid hit phenomenon it is ensured that the stability of system.
Specifically, above-mentioned throttling arrangement 3 can be one of electric expansion valve, silicon valve, heating power expansion valve；From control and
Considering of cost is set out, and this is sentenced and is preferred from electric expansion valve；Because electric expansion valve is capable of precise control coolant
Flow；Response speed is faster than heating power expansion valve, can reach required aperture in time, improves systematic function, adapts to bigger
Temperature regulating range.
Further, the pipeline between the heat exchanger 13 of outer machine 1 and each throttling arrangement 3 is in series with a two-way shut-off valve 6,
So can with Non-follow control open and close valve element to control coolant by with cut-off, for install and maintenance air conditioning system provides convenient.
Refer to Fig. 2, the multi-split air conditioner now this utility model being provided progress control method in a heating mode
Illustrate.This heating operation controlling method comprises the following steps：
Step S1：Air conditioning system starts heating mode, can be with the startup of implementation pattern by machine side plate in remote control meeting；
Step S2：Controller detects whether each interior machine is in opening, because according to the needs in each room, is not every
Secondary all can start all of interior machine simultaneously, controller detects the interior machine of unlatching by this step；
If, i.e. interior machine is in opening, then enter into step S4：Controller send instruction will be in unlatching shape
The corresponding electromagnetic valve of interior machine of state is opened；
If not, i.e. interior machine is closed, then enter into step S3：Controller send instruction will be in non-unlatching
The corresponding closed electromagnetic valve of interior machine of state.
Can also be with by target setting temperature Ts, to the interior machine being in opening, set run time tsAfterwards, judge
Indoor real time temperature T1>TsWhether+A sets up, and wherein, A is default permission float temperature；
If, i.e. indoor temperature T1Reach the temperature of predetermined set, now then controller sends instruction and enters step
Rapid S6：By corresponding for this interior machine closed electromagnetic valve；
If it is not, temperature T of interior1It is not up to the temperature of predetermined set, then keep being in step S4：The corresponding electricity of this interior machine
Magnet valve remains on, and continues as room supply heat.
After interior mechanism heat reaches room design temperature condition, the corresponding electromagnetic valve of machine in controller cut out, less than setting
Temperature conditionss, then the electromagnetic valve opening in real time machine in corresponding proceeds to heat, and not only avoids air conditioning system excessively to heat
Temperature, also avoids ambient temperature too low simultaneously, improves multi-split air conditioner and heat comfortableness.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
