Realize that the bidirectional throttle decompression of refrigerant allows refrigerant so that boiling point reduces using two-way adjustable throttling It evaporates and absorbs in heat exchanger.
Detailed description of the invention
Fig. 1 is the systematic schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole 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.
All components for not showing refrigerant circulation and air duct in above-described embodiment completely in implementation process, are selected different It is auxiliary that the common refrigeration such as high-pressure reservoir, gas-liquid separator, oily separation, filter, drier are arranged in refrigerant circuit in refrigerant Filter is arranged in water pipe in part, and silencer, auxiliary heater, sterilizing unit is arranged in air duct in the water process attachment such as sterilizing unit Equal air-treatments attachment, changes blower position, cannot be considered as and carry out substantial improvements to the utility model, should belong to this reality With novel protected range.
The words such as " first " used herein, " second " limit component, those skilled in the art will appreciate that " One ", the use of the words such as " second " is intended merely to facilitate in description and distinguishes to component.Unless otherwise stated, on Predicate language has no special meaning.
Finally it should be noted that: above-described embodiment is the preferred embodiment of the utility model, is not to this is practical The limitation of new technique scheme, as long as the technical side that can be realized on the basis of the above embodiments without creative work Case is regarded as falling into the rights protection scope of the utility model patent.
