Enter into after magnet valve 252 in indoor heat exchanger 250.Coolant carries out condensing heat release with to interior in the second heat exchanging part 2502 first
Air is heated, and is then entered into the first heat exchanging part 2501 through fully on Dehumidification controlling valve 257 again and is continued condensation
Heat release, further heats to room air.Coolant after heat exchange is flowed out after 256 reducing pressure by regulating flow of indoor restricting element
Indoor heat exchanger 250, now on the first pipeline 21 first control valve 23 close, on the second pipeline 22 first control valve 23 open
Open, coolant flowed to the first refrigerant passage 241 of cold heat exchanger 24 and after the 4th electromagnetic valve 254 through the second pipeline 22
On the first control valve 23 after again entered into the second refrigerant passage 242 of cold heat exchanger 24, last coolant flow to and enters port
16, so as to flow back to off-premises station 1.Complete two control multi-connected machines 100 heats circulation.
When indoor unit constant temperature dehumidification, the first electromagnetic valve 251 and the 3rd electromagnetic valve 253 are opened, close the second electromagnetic valve
252, Dehumidification controlling valve 257 is reducing pressure by regulating flow element.Coolant is discharged and flows to gas-liquid separation from the discharge port 17 of off-premises station 1
Device 20, coolant carry out gas-liquid separation in gas-liquid separator 20, and the gas coolant separated is flowed out by gas outlet 202,
Gaseous coolant is entered in indoor heat exchanger 250 after the first electromagnetic valve 251.As stream is to the cold of indoor restricting element 256
Matchmaker is gaseous coolant, therefore indoor restricting element 256 primarily serves the purpose for adjusting flow, and gaseous coolant is in the first heat exchanging part
2501 are carried out condensing heat release and are heated with the air after to being cooled down by the second heat exchanging part 2502, and return air is heated to what is needed
Leaving air temp, while coolant is condensed into liquid, then coolant again after the effect of the reducing pressure by regulating flow of Dehumidification controlling valve 257,
The coolant of liquid enters into the second heat exchanging part 2502, is evaporated heat absorption to reduce indoor moisture in the second heat exchanging part 2502
The temperature of air, then vapor be liquefied as water droplet to the cold, so as to reached interior constant temperature dehumidification purpose.And the coolant after exchanging heat
Flow to through the 3rd electromagnetic valve 253 and enter port 16, so as to flow back to off-premises station 1.The constant temperature for completing two control multi-connected machines 100 is removed
Wet circulation.
Indoors during unit constant temperature dehumidification, air is blowed to the second heat exchanging part 2502 and is dehumidified by indoor fan, then
The first heat exchanging part of air flow 2501 after dehumidifying is heated.
The indoor set component of two control multi-connected machines 100 according to embodiments of the present invention, arranges first by unit indoors
Electromagnetic valve 251, the 4th electromagnetic valve 254 and Dehumidification controlling valve 257, it is achieved thereby that the constant temperature dehumidification work(of two control multi-connected machines 100
Energy.
Some embodiments of the invention, one-way control valve 255 are check valve.It follows that check valve is not only able to
Coolant is directed to into indoor restricting element 256, but also the coolant for flowing through check valve can be avoided to produce backflow phenomenon, so that
The simple structure of one-way control valve 255 is obtained, the reliability of the work of two control multi-connected machine 100 is improved.
Alternatively, indoor restricting element 256 is electric expansion valve.So as to the throttling that ensure that indoor restricting element 256 is dropped
