Discharge chamber in machine.Indoor heat exchanger is drained into through auxiliary exhaust mouthful.Now, supercooling apparatus have after cold effect to main road refrigerant
Really, it is lowered into the refrigerant specific enthalpy of outdoor heat exchanger.Imported and exported than enthalpy difference so as to increase, and reduce the list of main compression cylinder
Position heating capacity power consumption, and the power consumption of the unit heating capacity of auxiliary compression cylinder is lower and volume heating capacity is higher, it is relatively conventional
Single stage compress heat pump assembly, improves the coefficient of performance in heating and heating capacity of heat pump assembly, while the exhaust of auxiliary compression cylinder
Pressure is identical with main compression cylinder but delivery temperature is relatively low so as to reduce the mixed temperature of exhaust.Wherein, the letter C in figure
Outdoor unit and indoor set region are represented respectively with alphabetical D.
When the first valve 71 is opened, bypass throttling arrangement close when, main road without after SAPMAC method, with main road after SAPMAC method
Unlike, enter the main compression cylinder and auxiliary compression cylinder of compressor simultaneously by outdoor heat exchanger low-pressure gas out simultaneously
High pressure superheater gas is compressed into, and indoor heat exchanger supercooling refrigerant out all flows through the main road of supercooling apparatus.Now
Supercooling apparatus do not possess after cold effect to main road refrigerant, and auxiliary compression cylinder does not exist still in pattern is effectively compressed
Friction loss caused by invalid compression.With respect to single stage compress heat pump assembly, coefficient of performance in heating is suitable, and heating capacity is due to increase-volume
And have lifting.
The heat pump assembly in most of operating mode after being run under chill formula, in nothing after under chill formula under only a small number of operating modes
Operation, such as heat pump assembly initial start stage, underload and small pressure ratio operating condition.Therefore, the heat pump assembly phase in the present embodiment
To single stage compress heat pump assembly, season coefficient of performance in heating is effectively lifted.
Wherein, effective aspirated volume ratio of auxiliary compression cylinder and main compression cylinder is 0.05~0.25, further optimization
Aspirated volume ratio be 0.08~0.15.
Bypass throttling arrangement is the electric expansion valve that function is closed with valve, or the electric expansion valve series connection of function is closed with valve
There is the orifice union of capillary, main road throttling arrangement is electric expansion valve or capillary etc..
Supercooling apparatus are the Intermediate Heat Exchanger with bilateral coolant channel.The bilateral refrigerant of supercooling apparatus is in Fig. 3
Counter-flow arrangement form, can also use down current arrangement form as an alternative.
Fig. 4 is another alternate embodiment system diagram of heat pump assembly, and unlike optimum embodiment, supercooling apparatus
Form replaces with flash evaporation form by Intermediate Heat Exchanger, and corresponding bypass throttling arrangement replaces with main road first throttle device and throttles
Device 75, main road throttling arrangement is then changed into main road second throttling device i.e. throttling arrangement 74, while increased electromagnetism two-port valve i.e.
The second valve 73 in Fig. 4.In the alternate embodiment, indoor heat exchanger supercooling refrigerant out is through main road first throttle device
Middle pressure two-phase state, the gas-liquid separation into supercooling apparatus are down in throttling, and the gas separated enters through gas-liquid separator presses
The auxiliary compression cylinder of contracting machine, the liquid separated enters the shell of compressor through main road second throttling device, outdoor heat exchanger
In vivo, motor is laggard becomes owner of compression cylinder for cooling, through main compression cylinder and auxiliary compression cylinder compression is paramount presses through warm refrigerant
Gas drains into indoor heat exchanger by the main vent and auxiliary exhaust mouthful of compressor.The first valve 71 is closed, the second valve is opened
73, then supercooling apparatus, have after cold effect to main road refrigerant.Conversely, opening the first valve 71, the second valve 73 is closed,
, to main road refrigerant without after cold effect, now low pressure refrigerant gas are simultaneously into the main compression cylinder of compressor for supercooling apparatus
With auxiliary compression cylinder.In the embodiment supercooling apparatus do not exist heat transfer temperature difference, therefore under supercooling pattern run when have compared with
Supercooling effect high.First and second throttling arrangement in the alternate embodiment can be electric expansion valve, capillary etc., electromagnetism two
Port valve can also be substituted by the three-way solenoid valve with equal function.Supercooling apparatus in the embodiment can be two-way shwoot
Device, and increase necessary four-way reversing valve and realize refrigerating function.Wherein, there are at least two compressions in parallelly compressed finger herein
Chamber fluid different at least two-way respectively is compressed simultaneously.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
