The delivery outlet of above-mentioned compressor 1 is connected to the input port of condenser 3 by pipeline, sets on this pipeline Putting the first check valve 2, outdoor fan 4 is condenser 3 heat radiation blowout hot blast, and the delivery outlet of condenser 3 passes through Pipeline is connected to the input port of fluid reservoir 5, the delivery outlet of fluid reservoir 5 respectively by the first branch road, second Road is connected to the kind of refrigeration cycle input port of indoor apparatus of air conditioner, wherein, the first branch road arrange the 3rd check valve 8, Being sequentially arranged frequency conversion fluorine pump the 6, second check valve 7 on second branch road, frequency conversion fluorine pump 6 connects converter;Refrigeration Circulation input port is connected to the input port of vaporizer 15, the 3rd branch road respectively by the 3rd branch road, the 4th branch road Being sequentially arranged the first electromagnetic valve 12, heating power expansion valve 14, the 4th branch road arranges the second electromagnetic valve 13, dried Filter 9 is arranged on the 3rd branch road, the input of the 4th branch road;The delivery outlet of vaporizer 15 passes through the 5th branch road Be back to the input port of compressor 1 connected, the 5th branch road is sequentially arranged electromagnetic valve of gas circuit 16, Gas-liquid separator 17, the delivery outlet of vaporizer 15 is connected to the output pipe of compressor 1 also by the 6th branch road, On 6th branch road, the 4th check valve 18 is set;Vaporizer 15 is by electric heater 11 heat supply, indoor fan Indoor air is blown over from vaporizer 15 by 10, blowing cold air.
In the present embodiment, indoor fan is EC blower fan, stepless speed regulation, bears according to air-conditioned room actual motion Lotus Intelligent Matching blower fan power, changes wind speed, it is provided that on enough circulation of air flow dynamic foundations, effectively reduce Consumption of data center.Indoor fan uses speed regulator regulation rotating speed, it is achieved energy-saving run also ensures system pressure Stable.
Indoor fan can increase blast cap above unit and directly blow;Or connect airduct blow;Or use Blowing in blower fan sinking underground, is directly sent under floor by cold wind, then blown by air port, saves for data center Space, floor board for machine room is electrostatic floor, cold air is formed one " plenum chamber " under electrostatic floor, also Make to blow more uniform and stable.
The check valve assembly effect when heating is the flow resistance in order to increase cold-producing medium, reduces cold-producing medium Flowing velocity, makes cold-producing medium fully evaporate at off-premises station, and the refrigerant gas making compressor discharge becomes refrigeration Agent liquid, improves air-conditioning heating effect.
The present embodiment can be operated in Three models:
The first mode compression mechanism cold pattern, condition is that ambient temperature is when being higher than 21 DEG C.Now compressor 1 isolated operation, concrete work process is as follows:
The high-temperature high-pressure gas refrigerant produced in compressor 1, by the first check valve 2, enters in condenser 3 It is condensed into the liquid of high pressure low temperature, enters heating power expansion valve by fluid reservoir the 5, first branch road, the 3rd branch road In 14, throttling expansion is the liquid of low-temp low-pressure, and then entering vaporizer 15 evaporation endothermic becomes low-temp low-pressure Gas, then return to compressor 1 continues cycling through by electromagnetic valve of gas circuit 16, gas-liquid separator 17.
The mixed model that the second mode compression mechanism cold+frequency conversion fluorine pump is energy-conservation, condition is that bad border temperature is less than 21 DEG C higher than 5 DEG C time.Now compressor and frequency conversion fluorine pump run simultaneously, and concrete work process is as follows:
The high-temperature high-pressure gas refrigerant produced in compressor 1, by the first check valve 2, enters in condenser 3 Being condensed into the liquid of high pressure low temperature, the frequency conversion fluorine pump 6 entered in the first branch road by fluid reservoir 5 improves pressure, Entering throttling expansion in heating power expansion valve 14 by the second check valve the 7, the 3rd branch road again is the liquid of low-temp low-pressure Body, then entering vaporizer 15 evaporation endothermic becomes the gas of low-temp low-pressure, then by electromagnetic valve of gas circuit 16, Gas-liquid separator 17 returns to continue cycling through in compressor 1.When frequency conversion fluorine pump 6 runs, frequency conversion fluorine pump 6 There is pressure reduction in two ends, frequency conversion fluorine pump 6 outlet pressure is more than inlet pressure, the 3rd check valve 8 of the i.e. first branch road Two ends there is pressure reduction, inlet port pressure be less than outlet pressures, the 3rd check valve 8 is obstructed.
Among these, compressor and frequency conversion fluorine pump run simultaneously, and frequency conversion fluorine pump maintains a fixed frequency, Run by frequency conversion fluorine pump auxiliary compressor, effectively reduce compressor condensing pressure, temperature, reduce compressor Power consumption, improves refrigerating capacity, increases systematic energy efficiency ratio.
The third pattern frequency conversion fluorine pump energy saver mode, condition is that ambient temperature is when being less than 5 DEG C.Concrete work Process is as follows:
Frequency conversion fluorine pump 6 gives cold-producing medium power, cold-producing medium through the second check valve the 7, the 4th branch road (without Heating power expansion valve 14, is not required to throttling) to enter evaporation endothermic in vaporizer 15 be the gas of low-temp low-pressure, pass through 6th branch road enters condenser 3 and condenses the liquid that heat release is low-temp low-pressure, then returns to the by fluid reservoir 5 In four check valves 18, then by frequency conversion fluorine pump the 6, second check valve the 7, the 4th branch road, the 4th check valve 18 continue cycling through.
Among these, frequency conversion fluorine pump replaces compressor to drive cold-producing medium to circulate in systems as dynamical system, Power consumption well below compressor cooling, frequency conversion fluorine pump can with the change regulating frequency of ambient temperature, Thus reaching energy-conservation purpose, the lowest energy-saving effect of outdoor temperature is the most obvious.
After server cabinet 21 bulk supply, open the equipment such as server, air-conditioning 20.When starting normal work After work, server sheds substantial amounts of heat, server fan take out of, simultaneously in indoor fan 10 driving effect Under, air constantly circulates, and heat enters the return air inlet of air-conditioning along top, room, and return air is through drainage screen mistake Filter carries out heat exchange or heating again, adds wet process with vaporizer, then is sent under floor by indoor fan by cold air, Cold air is sent entrance server and is carried out heat exchange from floor.When machine room actual motion, server load is in The state being continually changing.Time at full capacity, air-conditioning full-speed operation;During load reduction, air-conditioning draught fan automatic speed regulation, Reduce rotating speed to run.The most fully having ensured actual refrigeration demand, meanwhile, operation of air conditioner is the most intelligent, More energy-efficient.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is, based on above-mentioned design On the premise of principle, for solving same technical problem, even if doing on architecture basics disclosed in this invention Some gone out without substantial change or polishing, the essence of the technical scheme used still as the present invention, Therefore it should also be as in protection scope of the present invention.
