Description
Technical field
The multi-online air-conditioning system run the present invention relates to air-conditioning technical field more particularly to a kind of automatic emergency and its control
Method processed.
Background technique
In many special use occasions, such as national defence, hospital etc., air-conditioning is required to run without interruption in special time period,
To guarantee that national defence equipment local environment or operating room environment have stationary temperature condition.But any equipment is all not precluded within
Occur disorderly closedown caused by operation exception, components exception or components aging etc., this cancel closedown under extreme operating condition
Do not allow in special occasions.Currently, there are many air-conditioning equipments that emergency operating may be implemented on the market, still, people is required
It just can star after work manual operation, seriously affect the stability of temperature condition in special occasions
Therefore, how to solve air-conditioning equipment leads to the environment temperature of air conditioning area adjusted when cancel closedown occurs in special occasions
The problem of degree fluctuation is technical problem urgently to be resolved in the industry.
Summary of the invention
The present invention proposes the multi-gang air-conditioner system of automatic emergency operation to solve above-mentioned problems of the prior art
System and its control method.
The present invention proposes a kind of multi-online air-conditioning system, including indoor unit and outdoor unit, wherein is directed to same conditioned area
Domain is all provided in the connecting pipe of every indoor unit and every outdoor unit at least provided with two indoor units and at least two outdoor units
There is electrically operated valve, the electrically operated valve is controlled by the mainboard of air-conditioning system.
In one embodiment, the multi-online air-conditioning system is equipped with the indoor unit and two same loads of two same loads
Outdoor unit.
The present invention also proposes that a kind of control method of above-mentioned multi-online air-conditioning system, this method connect when the mainboard of air-conditioning system
After receiving operating instruction, controls indoor unit and outdoor unit puts into half operation, the other half is spare；When any indoor unit or
When outdoor unit breaks down, mainboard controls electrically operated valve and automatically switches stand-by equipment.
The beneficial effects of the invention are as follows：Guest machine is equipped with to indoor unit and outdoor unit for same air conditioning area, even if
When exceedingly odious condition or individual plants occur abnormal, system can be set with the equipment of automatic shield cancel closedown spare
It is standby to come into operation, guarantee that the temperature for being conditioned air conditioning area is stablized.
Detailed description of the invention
Fig. 1 is the pipeline valve schematic diagram of indoor unit or outdoor unit；
Fig. 2 is multi-line system connection schematic diagram.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples：
The present invention proposes a kind of multi-line system and its control method.As shown in Figure 1, in the system, outdoor unit or indoor unit 1
The solenoid valve 1-1 and 1-2 for automatically controlling refrigerant on-off are equipped in connecting tube.The solenoid valve is also possible to other types
Have the function of on-off valve member, such as electric expansion valve or other electric two-way valves.The valve member can be outdoor unit or interior
Interior design is included when machine dispatches from the factory, and is also possible to add when project installation.If increased when project installation, need with it is corresponding
The mainboard of air-conditioning system be connected, and controlled by mainboard.
Fig. 2 is the connection schematic diagram of multi-line system.As illustrated in fig. 2, it is assumed that the multi-line system includes 4 outdoor unit 2-
1,2-2,2-3 and 2-4, including n platform indoor unit, 3-1,3-2 ... 3-n, wherein 3-1 and 3-2 is mounted on the same conditioned area
In domain, for adjusting the air themperature in the same air conditioning area, this two indoor units are connected and are led to using the same line control machine 4
Cross its control.
In order to realize special occasions air-conditioning equipment reserve operation emergency operating in other words, having time in the place
Region is adjusted to carry out Selection and Design all in accordance with twice of conventional type selecting load, for example, according to conventional type selecting air conditioning area（Room）
It inside only needs that 1 3-1 indoor unit is installed, when 3-1 is when breaking down, which does not have air-conditioning equipment to carry out temperature tune
Section, so, it includes 3-1 and 3-2 that the technical program installs 2 indoor units simultaneously in the area.It, should according to this design method
Indoor unit type selecting in place is twice of conventional type selecting, and similarly, outdoor unit type selecting is also twice of conventional type selecting.
The control method of multi-line system proposed by the present invention is：
When breaking down in system without any indoor unit and outdoor unit, the indoor unit in same air conditioning area is being received
After the instruction of the booting operation sent to line control machine or remote controler, only open the indoor unit of half quantity in the air conditioning area into
Enter working condition, in addition the indoor unit of half quantity keeps standby mode.
When wherein 1 indoor unit or the outdoor unit that are mounted on same air conditioning area in system break down, such as indoor unit
System board issues the solenoid valve that instruction is closed in 3-1 indoor unit connecting tube when 3-1 disorderly closedown, with the stream of block refrigerant
It is logical, while control instruction is issued to spare indoor unit 3-2, and open the electronic valve on indoor unit 3-2 pipeline, throw it immediately
Enter working condition.
When the outdoor unit 2-1 in system breaks down at runtime, other outdoor units are according to the ability need of indoor unit
Operating status is automatically engaged, the circulation of block refrigerant is automatically closed in the solenoid valve in the connecting tube of outdoor unit 2-1.
The processing mode that indoor unit in the same air conditioning area receives after the instruction of line control machine is as follows：It is same to be mounted on
Illustrate for indoor unit 3-1 and 3-2 in one air conditioning area, as indoor unit 3-1 and 3-2 all normal, line control machine transmission is opened
After machine operating instruction, indoor unit 3-1 and 3-2 receive power-on instruction, and system board does not have received any appearance
The signal of failure, only indoor unit 3-1 puts into operation state at this time, and indoor unit 3-2 is spare；When system board detects indoor unit 3-
1 breaks down, or when receiving indoor unit 3-1 by line control machine and breaking down, system board is controlled on indoor unit 3-1 pipeline
Valve disconnects the runner of refrigerant, and the valve being also turned on indoor unit 3-2 pipeline controls its state that puts into operation.
The present invention is equipped with guest machine to indoor unit and outdoor unit in same air conditioning area, even if in exceedingly odious condition,
Or when individual plants appearance exception, system can come into operation stand-by equipment with the equipment of automatic shield cancel closedown, guarantee
The temperature for being conditioned air conditioning area is stablized
Above embodiments are for illustrating this creating conception of the invention and specific embodiment, it is noted that for ability
For the those of ordinary skill in domain, without departing from the inventive concept of the premise, various modifications and improvements can be made, these
Belong to protection scope of the present invention.
