Detailed description of the invention
With the following Examples this utility model is further described.
The magnetic suspension VRF Air Conditioning System that the present embodiment provides, system diagram is as shown in Figure 1.Magnetic suspension multi-connected air conditioner
The system of group is included in the indoor units part on the A left side, demarcation line and the outdoor unit part on the right of the A of demarcation line.Outdoor unit
Including magnetic suspension compressor 1 and controller (not shown), magnetic suspension compressor 1 is stepless load-adjusting compressor.Indoor units is provided with
Return air probe (not shown)；Outdoor unit is provided with temperature probe (not shown), with detection, feedback real time temperature.Controller according to
The cold that the indoor temperature that each return air probe is detected is actually required to adjust unit, and detected according to temperature probe
Outdoor temperature is to adjust the actual cold that can provide of unit, and controller feeds back magnetic suspension compressor 1 then, thus by magnetic suspension
Compressor 1 is adjusted to load or unload state, thus realizes energy-conservation, improves air conditioning unit Integrated part-load value.
Magnetic suspension VRF Air Conditioning System has refrigeration and heats two kinds of mode of operations, specific as follows:
Refrigeration mode: cold-producing medium exports from the right-hand member of magnetic suspension compressor 1, passes sequentially through needle-valve 2 and high-voltage switch gear 31.Its
In, needle-valve 2 is used for regulating throughput, and high-voltage switch gear 31 is it can be avoided that the air pressure of cold-producing medium is higher than the upper limit that system can bear.
Then, cold-producing medium flows to First Heat Exchanger 51 by cross valve 4.Under the effect of First Heat Exchanger 51 and fan 52, cold-producing medium
Condensation heat release, temperature reduces.Then, cold-producing medium passes sequentially through device for drying and filtering 6 and check valve 7(the first electric expansion valve 8 with single
In parallel to valve 7, the first electric expansion valve 8 is in cut-off state) after, it is split into bypass branch and kind of refrigeration cycle branch road.
Bypass branch: cold-producing medium passes sequentially through the 3rd electric expansion valve 15, subcooler 9, vapour liquid separator 14.Wherein,
Three electric expansion valves 15 make cold-producing medium throttling and evaporation thus take away the heat of subcooler 9；Vapour liquid separator 14 is for by cold-producing medium
In gas separate with liquid.Then, after cold-producing medium passes sequentially through low tension switch 32 and needle-valve 2, flow to magnetic suspension compressor 1,
The most again it is back in refrigeration system.Wherein, low tension switch 32 is used for preventing system pressure too low.
Kind of refrigeration cycle branch road: cold-producing medium passes sequentially through subcooler 9, granular membrane 10 parallel with one another and device for drying and filtering
After 6, then by liquid pipe stop valve 11, enter indoor units part.Indoor units part includes three indoor units, each indoor
The most corresponding heat exchange branch road of unit.In each bar heat exchange branch road, cold-producing medium passes sequentially through the second electric expansion valve 16, separatory
17 and second heat exchanger 121.Wherein, the second electric expansion valve 16 makes cold-producing medium throttling, blood pressure lowering, decreases system loss, protects
Card refrigeration.Liquid-dividing head 17 is for mixing gas-liquid two-phase cold-producing medium sufficiently uniformly；Cold-producing medium is in the second heat exchanger 121
Evaporation endothermic, thus freeze, cold wind is blowed by pressure fan 122.After cold-producing medium is by each bar heat exchange branch road, it is pooled to a road, continues
And after passing sequentially through steam pipe stop valve 13, cross valve 4, vapour liquid separator 14, low tension switch 32 and needle-valve 2, flow to magnetic suspension pressure
Contracting machine 1, completes kind of refrigeration cycle.
According to the needs of client, the quantity of indoor units can expand to 8 or more than.Due to indoor units quantity relatively
Many, system pipeline is longer.In the prior art, the longer meeting of system pipeline causes cold-producing medium in throttling (carrying out at expansion valve) premise
Front evaporator, affects refrigeration. and for this problem, the kind of refrigeration cycle branch road of the present embodiment is provided with subcooler 9.Subcooler 9 cold
But effect decreases cold-producing medium by the evaporation capacity before the second electric expansion valve 16, decreases what cold-producing medium produced in this place
Flash gas, thus be that the second electric expansion valve 16 creates more preferable flow reduction conditions, improve cooling system efficiency.
Heating mode: cold-producing medium exports from the right-hand member of magnetic suspension compressor 1, passes sequentially through needle-valve 2, high-voltage switch gear 31, four
After logical valve 4 and steam pipe stop valve 13, enter indoor units part, be then diverted to three described heat exchange branch roads.Cold-producing medium is successively
By being pooled to a road after the second heat exchanger 121, liquid-dividing head 17 and the second electric expansion valve 16.Wherein, cold-producing medium changes second
Liquidation exothermic reaction in hot device 121, thus heat, pressure fan 122 is by heat blow.Cold-producing medium after collecting passes sequentially through the cut-off of liquid pipe
Valve 11, granular membrane 10 parallel with one another and device for drying and filtering 6.Then, cold-producing medium is by, after subcooler 9, being split into bypass
Branch road and heat circulation branch road.Wherein, subcooler 9 reduces cold-producing medium before follow-up link (at the first electric expansion valve 8) throttles
Evaporation capacity, thus create more preferable flow reduction conditions, improve heating efficiency.
Bypass branch: cold-producing medium passes sequentially through the 3rd electric expansion valve 15, subcooler 9, vapour liquid separator 14, low tension switch
32 and second after needle-valve 2, flow to magnetic suspension compressor 1, are the most again back in heating.Similarly, the 3rd electronics is swollen
Swollen valve 15 makes cold-producing medium throttling and evaporation thus takes away the heat of subcooler 9.
Heat circulation branch road: cold-producing medium passes sequentially through the first electric expansion valve 8(check valve 7 and is in cut-off state), be dried
Filter 6 and First Heat Exchanger 51.Wherein, the first electric expansion valve 8 makes cold-producing medium throttling, blood pressure lowering, decreases system loss, protects
Card heating effect.Cold-producing medium is evaporation endothermic under the effect of First Heat Exchanger 51 and fan 52.Then, cold-producing medium passes sequentially through four
After logical valve 4, vapour liquid separator 14, low tension switch 32 and needle-valve 2, flow to magnetic suspension compressor 1, complete to heat circulation.
Due to the present embodiment provide magnetic suspension VRF Air Conditioning System use magnetic suspension compressor 1, refrigeration system without
Add refrigeration oil so that the reliability of unit increases, it addition, also make First Heat Exchanger 51 and the heat exchange of the second heat exchanger 121
Pipe is internal to be adhered to without oil film, thus improves First Heat Exchanger 51 and the heat exchange efficiency of the second heat exchanger 121.
Last it should be noted that, above example is only in order to illustrate the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Logical it will be appreciated by the skilled person that the technical scheme of utility model can be modified or equivalent, without deviating from this reality
Spirit and scope by new technique scheme.
