Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of revealed multi-split air conditioner of the utility model, including an outdoor unit and multiple
Indoor unit, in which:
The indoor unit includes inner casing body 1, inside indoor heat exchanger 2 and indoor fan 3, shell upper end are installed
With air inlet, lower end has air outlet, and indoor fan is mounted on air inlet, by the wind of inspiration by after heat exchanger heat exchange from
Air outlet discharge, the indoor heat exchanger lower section are additionally provided with water dish 4, and bottom is connected to outdoor by water pipe.
The outdoor unit includes outer cage body, inside screw compressor 5, outdoor fan 6, the first solenoid valve are installed
7, second solenoid valve 8, third solenoid valve 9, the 4th solenoid valve 10, outdoor heat exchanger 11 and Bidirectional adjusting valve 12, screw pressure
The gas outlet of contracting machine is divided into two-way, is separately connected the first solenoid valve and second solenoid valve, and air entry is also classified into two-way, connects respectively
Third solenoid valve and the 4th solenoid valve are connect, wherein second solenoid valve and the 4th solenoid valve other end in piping connection room by exchanging heat
Device one end, the first solenoid valve and the third solenoid valve other end are sequentially connected outdoor heat exchanger, two-way adjustable throttling by pipeline
The other end for being connected to indoor heat exchanger afterwards forms circulation line, and outdoor fan is mounted at outdoor heat exchanger.
The indoor heat exchanger and outdoor heat exchanger are finned tube exchanger or micro-channel heat exchanger.
The explanation of working principle is carried out to the air-conditioning system of the utility model below, specifically:
Under cooling condition, the first solenoid valve, the 4th solenoid valve are opened, closes second solenoid valve, third solenoid valve, refrigerant
It is pressurized, by the first solenoid valve, is then flowed to outdoor heat exchanger (condenser) within the compressor, it is extraneous within the condenser
Surrounding air is condensed into refrigerant liquid, then send to two-way adjustable throttling, the reducing pressure by regulating flow in throttle valve, drops its boiling point
It is low, it prepares for evaporation endothermic refrigeration under the low temperature in evaporator, after throttling, refrigerant becomes the gas-liquid mixed of low-temp low-pressure
Object then flows into indoor heat exchanger, and evaporation endothermic freezes in heat exchanger indoors.After evaporating, refrigerant is by the 4th electricity
Magnet valve enters screw compressor, completes circulation.
Under cooling condition, the glide path of refrigerant are as follows: screw compressor → the first solenoid valve → outdoor heat exchanger →
Two-way adjustable throttling → indoor heat exchanger → four solenoid valves → screw compressor.Under sleep state, close indoor
The blower of machine realizes the operation of zero noise.
Under heating condition, principle is to close the first solenoid valve, the 4th solenoid valve, opens second solenoid valve, third electromagnetism
Valve, refrigerant are pressurized within the compressor, by second solenoid valve, then flow to indoor heat exchanger, at this time indoor heat exchanger
As condenser, refrigerant liquid is condensed by room air in heat exchanger indoors, is freezed using the high temperature and pressure in pipeline
Agent gas is heated, then is sent to two-way adjustable throttling, the reducing pressure by regulating flow in throttle valve, makes the reduction of its boiling point, in outdoor
Evaporation endothermic refrigeration is prepared under low temperature in heat exchanger (evaporator), and after throttling, refrigerant becomes the gas-liquid mixed of low-temp low-pressure
Object then flows into outdoor heat exchanger, and gaseous state is flashed in outdoor heat exchanger.After evaporating, refrigerant passes through third
Solenoid valve enters screw compressor, completes circulation.
Under heating condition, the glide path of refrigerant are as follows: screw compressor → second solenoid valve → indoor heat exchanger →
Two-way adjustable throttling → outdoor heat exchanger → third solenoid valve → screw compressor.At this point, closing room under sleep state
The blower of interior machine realizes the operation of zero noise.
