The advantage of this class refrigerated air-conditioning system is: the efficient of the water transmission cold that thermal capacity is bigger is higher, and is convenient to Field adjustment for needed terminal cold.Its weak point is: very high to requirements in water quality, in order to slow down scaling (influence heat conduction) in the pipe network of dispensing cold, every interval also wanted with medicament to dredge the once huge heat-exchange system that is made of the water pipe network in one, two years.Secondly, in the whole exactly water pipe network leak and the workload of mending-leakage can not lacked.Can imagine that because the comprehensive intervention of water in air-conditioning system, the maintenance workload of prior art and maintenance cost all are appreciable.
Summary of the invention:
The present invention's purpose: in the refrigerated air-conditioning system engineering, by increasing the pressurizes refrigerant dispenser that mainly constitutes by refrigerated medium pump, replace the chilled water dispenser that transmits auxiliary facility formations such as the water of middle refrigerant medium of cold and water pump thereof as secondary, fundamentally solve above-mentioned maintenance workload and maintenance cost all is appreciable problem with this.
The present invention is achieved in that
At least contain in the refrigerated air-conditioning system of the present invention: condenser, compressor, evaporimeter and the flow controller four big refrigeration basic elements of character, and the cold-producing medium that is suitable for air conditioning condition, it is characterized in that: increased pressurizes refrigerant dispenser in the above-mentioned refrigerated air-conditioning system for its service, this pressurizes refrigerant dispenser comprise refrigerated medium pump and with the matching used low pressure liquid storing barrel of refrigerated medium pump, and, this refrigerated medium pump the bottom that highly is lower than the low pressure liquid storing barrel is set.
The present invention relates to the pipeline connecting method of characteristic: concentrate by low pressure pipeline through the low-pressure, liquid refrigerant of flow controller to be stored in the low pressure liquid storing barrel, then, directly low-pressure, liquid refrigerant is transported in the floor evaporimeter by refrigerated medium pump by low pressure pipeline, must be communicated with the low pressure liquid storing barrel and connect evaporimeter air return end to the low pressure pipeline of compressor, with the gas pressure balancing of maintenance low pressure liquid storing barrel and evaporimeter.
The present invention's characteristics compared with the prior art:
Since the present invention in refrigerated air-conditioning system by having introduced the pressurization dispenser of pump liquid towards cold-producing medium, and with this replace former cause comprise water as the intervention of refrigerant intermediate medium may, for variety of problems and the hidden danger of thoroughly having avoided water to cause in air-conditioning system have been created condition.
2. because above-mentioned " 1 ", for reducing the engineering cost of superelevation layer refrigerated air-conditioning system, reduce line service amount and maintenance cost, and the operating efficiency of raising air-conditioning (make the secondary that utilizes water transmit cold and become the once transmission cold by cold-producing medium execution itself that need not water) has been created condition again.
Description of drawings:
Fig. 1 has illustrated the refrigerated air-conditioning system prior art that allows water fully get involved of common employing to implement principle.
Fig. 2 has illustrated one embodiment of the present of invention principle.
P: evaporimeter; W: chilled water delivery system; B1: water pump; D: pressurizes refrigerant dispenser; B2: refrigerated medium pump; 1: condenser; 2: compressor; 3: the low pressure pipeline of outsourcing heat insulation layer; 4: the water pipe of outsourcing heat insulation layer; 5: the intermediate medium heat exchanger; 6: pressure piping; 7: device for drying and filtering; 8: flow controller; 9: water-cooled cold wind output unit; 10: air-cooler; 11: chilled water coil; 12: the water-cooled condensing unit; 13: condensation fan; 14: the low pressure liquid storing barrel of outsourcing heat insulation layer; 15: vaporation-type cold wind output unit.
The specific embodiment:
Illustrate by Fig. 1:
Owing to only rely on the dynamics of the height pressure reduction that causes by compressor 2 in the refrigerated air-conditioning system, after being difficult to directly drive the specified liquid refrigeration agent flux sinuate pipeline of process (flow resistance is bigger), enter the refrigeration air-conditioner that carries out associated room in the high-rise building more than tens meters even hundred meters again.
Therefore, be in the cold-producing medium of low-pressure state by flow controller 8, entering and during through the evaporimeter P in the intermediate medium heat exchanger 5, the refrigerating capacity that produces in the liquid refrigerant evaporation process, the water as the refrigerant medium that is driven by water pump is given in conduction, carries out the transmission of secondary cold by water.
For this reason, in the refrigerated air-conditioning system of routine, additionally increased the chilled water delivery system W that constitutes by intermediate medium heat exchanger 5 and water pump B1, and the supporting water-cooled cold wind output unit 9 that constitutes by air-cooler 10 and chilled water coil 11, the fan coil that the latter is commonly called as (low capacity) and water-cooled wind cabinet end-equipments such as (capacity greatly).
All things invariably divide into two, solved the problem of the primary operate as normal of refrigeration air-conditioner, but because the comprehensive intervention of water, and aforesaid variety of problems and hidden danger have produced in the refrigeration air-conditioner use that causes.
For fear of aforesaid variety of problems and hidden danger, external having developed can be replaced water and transmitted special-purpose chemical flowing material cold and that air-conditioning system is not had ill-effect,---purpose is: the problem that can solve knot " dirt " (reduction heat transfer coefficient) in the refrigerant heat-exchange system that pipeline constitutes, but, be used as transmitting the refrigerant medium of cold by its place of water, will improve the cost of refrigerated air-conditioning system engineering greatly, may not be practical.
Key problem in technology of the present invention is: got involved " refrigerated medium pump B2 " technology in the original scheme of above-mentioned refrigerated air-conditioning system, comprised that with replacement the refrigerant medium of water is got involved above-mentioned refrigerated air-conditioning system.But also can improve the efficient of refrigerated air-conditioning system therefrom.
The signal of Fig. 2 adopts refrigerated medium pump B2 to replace the design of the present invention of water pump B1 technology:
Be stored in the low pressure liquid storing barrel 14 by the low-pressure, liquid refrigerant of flow controller 8 is temporarily concentrated, then, B2 is transported to tens layers with low-pressure, liquid refrigerant by refrigerated medium pump, even among the higher floor evaporimeter P, by supporting air-cooler 10, force air and evaporimeter P to carry out the cold wind that forms after the heat exchange, the big wind-tunnel of trunk by the place level is sent, be distributed at last the room that each needs refrigeration air-conditioner again, the course of conveying of whole air-conditioning cold flow, need not as prior art need be by means of the water as middle refrigerant medium, and the chilled water dispenser W that constitutes of supporting water pump B1 and intermediate medium heat exchanger 5.Owing to do not transmit cold by the water secondary, so, terminal water-cooled cold wind output unit 9 is also simultaneously unnecessary, also can omit.
In the middle of the pressurizes refrigerant dispenser D that constitutes by refrigerated medium pump B2 and low pressure liquid storing barrel 14:
Connection evaporimeter P air return end to the low pressure pipeline 3 of compressor 2 must be communicated with low pressure liquid storing barrel 14, to keep the gas pressure balancing of low pressure liquid storing barrel 14 and evaporimeter P, otherwise refrigerated medium pump B2 just can't be pumped into low-pressure, liquid refrigerant the evaporimeter P there of eminence.For refrigerated medium pump B2 can be played one's part to the full, the bottom that refrigerated medium pump B2 should be arranged on low pressure liquid storing barrel 14 is appropriate.Low pressure liquid storing barrel 14 is stored in the low-pressure, liquid refrigerant that wait system cryogenic fluid pump B2 wherein goes out its dispensing and can not be gasified in order to stop outside heat and to enter and should be surrounded by heat insulation layer outward, making, more can not siphoned away by compressor 2.
