Offering question about the liquid refrigerant pressurization dispenser X in the present invention:
Just enable liquid refrigerant pressurization dispenser X when implementing refrigeration air-conditioner, now, room heat exchanger 1 is as room
Interior vaporizer uses, and set heat exchange device 5 uses as outdoor condenser.
This liquid refrigerant pressurization dispenser X structurally includes refrigerant fluid pump B and is positioned at this refrigerant fluid pump B
Top and with the low pressure receiver bucket D of this refrigerant fluid pump B adapted；Refrigerant fluid pump B is in the reality within waring and cooling air conditioning system
Effective head, determines the maximum actual rational height, i.e. maximum in building of the room heat exchanger 1 used as vaporizer
Actual level.
Described refrigerant fluid pump B: include liquid pump c (including its dragging motor) and surround this liquid pump c with stereogenic
Full seal type the first metal sealing shell d, this first metal sealing shell d is provided with the low of direct connection this liquid pump c
Pressure feed tube j and high pressure drain pipe f, is provided with on the top of this metal sealing shell b and can connect with low pressure receiver bucket D top
Gas pressure balancing pipe n, have at its lower bottom part and be provided with and low pressure receiver bucket D lower bottom part contains liquid refrigerant position
Fluid pressure balance pipe m, (diameter 6 millimeters i.e. can be used for liquid pump c and leaks on a small quantity the caliber of this aforesaid a pair equalizing main
The discharge purposes of cold-producing medium) need not the biggest；The lower bottom part of the low pressure feed tube j and low pressure receiver bucket D of this liquid pump c contains liquid
The position of cold-producing medium is connected, the high pressure drain pipe f of this liquid pump c: be finally connected with room heat exchanger 1 by refrigeration dosing valve P8；
Described low pressure receiver bucket D: be disposed thereon the low-pressure gas balance pipe H in portion by refrigeration air pressure double-beat drop valve P5
It is connected with the air entry of compressor 3 eventually, is disposed therein portion's feed pipe by the refrigeration supplying valve P6 on this pipeline finally and machine
Group heat exchanger 5 connects；
Described liquid refrigerant pressurization seam crossing involved by dispenser all uses non-removable weldering at connecting leg
Connect process implementing to combine.During additionally, enable this device, the change of related data in cooling condition will not be caused.
Owing to the fluid leakage problems of liquid pump c is insoluble, therefore, the structure at its complete machine refrigerant fluid pump B sets
Should both allow the leakage of liquid refrigerant on meter, but not allow the cold-producing medium of this leakage to enter into (quilt in the middle of airspace
Slattern), to this end, must take in structure:
It is positioned at fluid pressure balance pipe m and the gas pressure balancing pipe n in the middle of the first metal sealing shell d by allowing liquid pump c
Jointly acting on the inner chamber of this first metal sealing shell d, once leaked inside liquid pump c liquid refrigerant, but it can not
Can be further continued for passing through this first metal sealing shell d and enter airspace, can only flow from the fluid pressure balance pipe m of its lower bottom part
Enter low pressure receiver bucket D and deposit the bottom of liquid refrigerant, wait and again being used.The design concept of this process mechanism is:
Allow to leak liquid refrigerant at the liquid pump c within refrigeration system, but absolutely not allow this liquid refrigerant leaked to have can
And then go successively to the possibility of airspace.
Obvious: in liquid refrigerant pressurization dispenser X, to be capable of the above-mentioned liquid refrigerant that leaks guaranteeing liquid pump c
Can in internal system by all reclaiming the premise being utilized again be utterly:
The lower bottom part of the first metal sealing shell d constituting refrigerant fluid pump B necessarily be greater than: within low pressure receiver bucket D
Liquid refrigerant plane w, so, no matter the leak quantity of liquid refrigerant of liquid pump c has much, all can be complete by low pressure receiver bucket D
Portion is utilized after reclaiming in full again.The height of liquid refrigerant plane w is little and the most relevant with low and refrigeration system load, system
Refrigeration duty is the least, and this liquid refrigerant plane w is the highest, it should takes the height of the highest liquid refrigerant plane w, adds 10
Cm is just, so that it may obtain the numerical value of above-mentioned vertical gap H exceeded.
The Main Function of low pressure receiver bucket D is: temporarily store the set heat exchange device 5 through using as condenser the coldest
Liquid refrigerant that is after lime set and that come by Pipeline transport, is supplied to above-mentioned refrigerant fluid pump B at any time and uses: will
The room heat exchanger 1 used as vaporizer that this low-pressure, liquid refrigerant liquid pump hoists.
Offering question about the gaseous refrigerant pressurization dispenser K in the present invention:
Although the condensing pressure in waring and cooling air conditioning system is higher than evaporating pressure, self-dependent strength is by high-temperature gas
The height of several floor delivered to by cold-producing medium, and in way, the heavy resistance of pipeline to be overcome, can feel " unable to do what one wishes ", if it is possible to
By means of just right extra external force, (air pump a) assists to be delivered up gaseous refrigerant, and it is handy to feel.
Just enable gaseous refrigerant pressurization dispenser K when implementing cooling/heating air conditioner, now, room heat exchanger 1 is as room
Inner condenser uses, and set heat exchange device 5 uses as outdoor evaporator.
The structure of this gaseous refrigerant pressurization dispenser K is more simply too much than above-mentioned liquid refrigerant pressurization dispenser X,
It structurally includes air pump a (including its dragging motor) and surrounds full seal type second gold medal of this air pump a with stereogenic
Belong to and seal shell b, this metal sealing shell b is provided with the external air inlet connecting can being connected with compressor 3 air vent
Mouth and the external exhaust port that can be finally connected with room heat exchanger 1, and, allow the air entry of this air pump a face toward stretch
Enter the pipeline air-inlet mouth of pipe of this metal sealing shell b intracavity, and, the air entry of this air pump a should be with above-mentioned air inlet hole
Or there is clearance distance s between the air inlet mouth of pipe of pipeline, its value 2 millimeter is sufficient to；Although the plant capacity of air pump a
Being the biggest in central air conditioner system, but air leakage will not be big, otherwise, the workmanship of air pump a is the most problematic.Its
Purpose is to allow a large amount of high speed gaseous refrigerants discharged and sucked by this air pump a by compressor 3, it is possible to the simplest and the most direct straight line fortune
Flowing mode is directed into the internal of air pump a at high speed, is further continued for directly being discharged by pipeline after this air pump a pressure-raising.
Obviously, above-mentioned rectilinear clearance distance s is the least, when high velocity air crosses over this rectilinear clearance distance s, and its flow area face
In long-pending the most descending ascending change procedure, " throttling " loss of the high-speed gas formed will be the least；In big merit
In the middle of the high velocity air of rate type, owing to this energy loss caused by problem that " throttles " can not be underestimated.
If this clearance distance s does not exists in pipeline, the most above-mentioned " throttling " problem does not exists, but, as system
Must be all to use easy vaporization type liquid for cryogen, leak the gas in this metal sealing shell b inner chamber, in external condition
It is extremely easy to again liquefaction during (such as: temperature and pressure etc.) change, which forms this cold-producing medium that leaks and can there is liquefaction and be accumulated to
Contact with the dragging motor in this metal sealing shell b inner chamber after certain quantity and make the chance of this motor damage.
It is not difficult to find out: the gap of above-mentioned rectilinear clearance distance s, can pass through to be somebody's turn to do in formation the one of " clearance distance s gap "
Bore a hole (such as: several millimeters) on the tube wall of root air inlet pipe to replace, its function and " gap of clearance distance s "
It is the same.Therefore also should be considered as relating to the claim in " gap of clearance distance s ": with above-mentioned " one
A hole is bored on the tube wall of the air inlet pipe that root is complete " it is equivalent, i.e. the same.
During additionally, enable this device K, the change of related data in heating condition can be caused.
Owing to the present invention is by gaseous refrigerant pressurization dispenser K relay extraly or afterburning behave, it is achieved power-assisted gas
Oneself is pushed to higher floor and realizes directly real to space air by the gaseous refrigerant in condenser normally by state cold-producing medium
Execute cooling/heating air conditioner and create condition.So will certainly improve outdoor in this heating air conditioner system the most therewith to make as vaporizer
The evaporating pressure of set heat exchange device 5, i.e. improve the cryogenic temperature of outdoor unit heat exchanger 5, then at outdoor low temperature ring
The outdoor heat drawn under this cold environmental conditions by evaporation endothermic under the conditions of border is disadvantageous.
For the evaporating pressure forced down in this heating air conditioner system in outdoor unit heat exchanger 5, i.e. evaporating temperature, it should join
Close the fine setting (bore is turned down) to reducer 6, suitably reduce the flow of liquid refrigerant so that evaporating temperature is reduced to original
Standard state (being suitable for being not less than indoor heating level during ambient temperature 7 DEG C) or think more suitably degree.Steam
Send out temperature the lowest, the most easily absorb the outdoor air heat under cold environmental conditions, but, this low-temperature heat quantity of absorption will subtract
Few.If additionally, outdoor environment temperature is on the low side, then, it is also possible to make above-mentioned evaporation temperature by turning the bore of reducer 2 down
Degree is the most suitably adjusted more on the low side.But too low evaporating temperature easily causes the outdoor set heat exchange used as vaporizer
Device 5 frosting, is disadvantageous in maintaining normal indoor heating operating mode.
Clearly as add gaseous refrigerant pressurization dispenser K in systems, converting cooling condition and heating work
During condition, then to coordinate the fine setting of choke valve 6 be needs, and otherwise, heating condition (nonstandard design) is difficult to reach preferably to work
State.Owing to needing the fine setting of choke valve 6 when cooling/heating air conditioner, then, then refrigeration air-conditioner of remapping is (despite standard work
Condition) time, the most also must finely tune choke valve 6, i.e. be changed back to standard work during refrigeration by nonstandard design when heating
Condition.
Gaseous refrigerant pressurization dispenser K structure design basic concept also: both allowed letting out of gaseous refrigerant
Leak but do not allow the cold-producing medium of this leakage to enter in the middle of airspace (being wasted).
In the middle of waring and cooling air conditioning system including the present invention, to accomplish that cold-producing medium therein absolutely not leaks at present is not
Possible, but, it should towards the direction effort of above-mentioned " cold-producing medium absolutely not leaks ", it is possible to even if accomplishing the most a bit, long-pending
The most just can become many, the design of the present invention is acted in line with this principle: such as, the critical component " cold-producing medium in the present invention
Liquid pump B " just belong to can never let out to airspace in the middle of normal course of operation with " gaseous refrigerant pressurization dispenser K "
Two full seal type parts of leakage refrigerant molecules.
