Abstract

The invention relates to a method for controlling an electromagnetic valve of a tri-zone air conditioner indoor unit. The method is operated inside the tri-zone air conditioner indoor unit and comprises the following steps: firstly, judging whether to supply power to a second indoor unit or to a third indoor unit after starting up an outdoor unit; turning on a first electromagnetic valve and a bypass electromagnetic valve and entering a second indoor unit operating mode when supplying power to the second indoor unit; and turning on a second electromagnetic valve and the bypass electromagneticvalve and entering a third indoor unit operating mode when supplying power to the third indoor unit. The method does not change the structure of the prior tri-zone air conditioner indoor unit; when the second indoor unit is turned on alone, the first electromagnetic valve corresponding to the second indoor unit is turned on, while the second electromagnetic valve corresponding to the third indoorunit is turned off just by the control method; meanwhile, the bypass electromagnetic valves are turned on to reduce system pressure; moreover, the turned off second electromagnetic valve is turned onfor 3 minutes per hour to ensure that oil inside the third indoor unit can be effectively returned to a compressor. The method prevents compressor energy from being consumed on a turned off indoor unit and improves the operating efficiency of a turned on indoor unit.

Description

One method for controlling electromagnetic valve of tri-zone air conditioner indoor unit
Technical field
The present invention relates to a kind of one and drag three air conditioners.Particularly relate to a kind of energy consumption that can avoid compressor on the indoor set of not opening, thereby can improve a method for controlling electromagnetic valve of tri-zone air conditioner indoor unit of the indoor set operating efficiency of unlatching.
Background technology
Air conditioner is a kind of device that makes its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat circulation.When air conditioner carries out kind of refrigeration cycle, compressed machine compression and the refrigerant that becomes high-temperature high-pressure state can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reduce its temperature and pressure, this low temperature, low pressure refrigerant absorb heat when flowing through the evaporimeter of indoor set, flow back in the compressor again after becoming the refrigerant of high-temperature low-pressure.Usually, air conditioner is divided into separate type air conditioner and wall-through type air conditioner, and separate type air conditioner then includes an one driven multiple air conditioner that is made of an off-premises station and Duo Tai indoor set." one drag many " air-conditioner is saved the favor that the space more and more is subjected to people with its simple installation.
Fig. 1 drags three air conditioner structure schematic diagrames.
As shown in Figure 1, one drag three air conditioners mainly to comprise an off-premises station 1 and three indoor set A, B, C.Off-premises station 1 is provided with refrigerant efferent duct 6 and refrigerant input pipe 7, then is provided with refrigerant input pipe 8 and refrigerant efferent duct 9 on indoor set A, B, the C, and corresponding continuous with the refrigerant pipe of off-premises station.From the liquid refrigerants of off-premises station 1 the refrigerant input pipe 8 of the refrigerant efferent duct 6 by off-premises station 1 and each indoor set A, B, C is offered every indoor set A, B, C.Enter the refrigerant of indoor set A, B, C will be respectively with each interior space in air carry out heat exchange, the refrigerant that becomes gaseous state through heat exchange will focus on the refrigerant input pipe 7 of off-premises station 1 through the refrigerant efferent duct 9 of indoor set A, B, C and flow back in the off-premises station 1.
Fig. 2 is the structural representation that drags three air conditioner magnetic valves.
As shown in Figure 2, drag three air conditioners for existing one, give electricity when off-premises station 1, because the first indoor set B1 and second, third indoor set B2, B3 are two independent systems, the open and close of the first indoor set B1 do not involve the problem of magnetic valve.And second, third indoor set B2, B3 are closed circuits, and as second, third indoor set B2, when B3 opens simultaneously, first magnetic valve 5 and second magnetic valve 6 are opened and running always; When the second indoor set B2 opened separately, first magnetic valve 5 and second magnetic valve 6 also were to open and running always; When should the 3rd indoor set B3 opening separately, first magnetic valve 5 and second magnetic valve 6 also are to open and turn round always.So the loss of compressor capacity part is on obsolete indoor set, and the indoor set B ability of opening can not improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of energy consumption that can avoid compressor on the indoor set of not opening, thereby can improve a method for controlling electromagnetic valve of tri-zone air conditioner indoor unit of the indoor set operating efficiency of unlatching.
The technical solution adopted in the present invention is: an a kind of method for controlling electromagnetic valve of tri-zone air conditioner indoor unit, be to drag in three indoor apparatus of air conditioner one to move: include and after starting off-premises station, at first judge it is to power to second indoor set, still give the power supply of the 3rd indoor set, if give the power supply of second indoor set, then open first magnetic valve and bypass solenoid valve, and enter the second indoor set operational mode; If give the power supply of the 3rd indoor set, then open second magnetic valve and bypass solenoid valve, and enter the 3rd indoor set operational mode.
The described second indoor set operational mode comprises the steps:
(1) open first magnetic valve and bypass solenoid valve,
(2) in the second indoor set running, judge whether the operation of second indoor set reaches 1 hour;
(3) if operation reaches 1 hour, then second magnetic valve was opened 3 minutes; Otherwise finish;
After (4) second magnetic valves are opened 3 minutes, judge whether second indoor set also continues operation;
(5) if second indoor set continues operation, then return step and begin the repetition subsequent step; Otherwise finish.
Described the 3rd indoor set operational mode comprises the steps:
(1) open second magnetic valve and bypass solenoid valve,
(2) in the 3rd indoor set running, judge whether the operation of the 3rd indoor set reaches 1 hour;
(3) if operation reaches 1 hour, then first magnetic valve was opened 3 minutes; Otherwise finish;
After (4) first magnetic valves are opened 3 minutes, judge whether the 3rd indoor set also continues operation;
(5) if the 3rd indoor set continues operation, then return step and begin the repetition subsequent step; Otherwise finish.
A method for controlling electromagnetic valve of tri-zone air conditioner indoor unit of the present invention, need not change existing one any structure that drags three indoor apparatus of air conditioner, only need in control program, to increase control method of the present invention is arranged, when the second indoor set list is opened, first magnetic valve of its correspondence is opened, and second closed electromagnetic valve of obsolete the 3rd indoor set correspondence, bypass solenoid valve is opened simultaneously, reduce system pressure, and in control method, append second magnetic valve of closing in per 1 hour and opened 3 minutes, the oil of the 3rd indoor set is effectively got back in the compressor.The present invention can avoid the energy consumption of compressor on the indoor set of not opening, thereby can improve the indoor set operating efficiency of unlatching.
