Hold the supply of low temperature chilled water（Such as food, pharmacy, petrochemical factory）.How at any time with security and stability user's cooling and to do
To it is energy-efficient be air conditioner refrigerating industry a problem.In warm area（Such as south China）Accomplish that this point is less problematic.
And the region of zero degree is likely lower than for outdoor temperature（Such as northern China cold district）, be user at any time cooling it is necessary in face of
Winter low ambient temperature（Low ambient temperature refers to that outdoor dry-bulb temperature is less than subzero）The problem of, this is just needed using refrigeration
Unit（Refrigeration unit refers to that constant temperature, constant current, the refrigeration plant of constant pressure cryogenic water can be provided）To carry out cooling.Double-condenser at present
Formula refrigeration unit mainly has following two：
The first is using water-cooled or the refrigeration unit of evaporative condenser refrigeration, such as uses water-cooling screw rod unit supporting
Outdoor cooling tower refrigeration, or using evaporating type condensing screw water cooling machine set refrigeration etc..But the shortcomings that this refrigeration unit, is, due to
Using water-cooled or the refrigeration unit of evaporative condenser refrigeration, it is necessary to use outdoor water cooling tower or Water spray evaporative condenser
Device, can high energy efficiency it be run in summer for outdoor water cooling tower or Water spray evaporative condenser, if low ambient temperature in the winter time
Under must then take certain antifreezing measures, such as run do not shut down always using water pump and cooling tower, keep the flowing of cooling water
To prevent from freezing, electrical heating is set up and in the winter time toward filling anti-icing fluid in cooling water using cooling tower or evaporative condenser for another example
Etc. preventing from freezing, power consumption and use cost are so both added, and easily causes equipment component to freeze because of misoperation, is made
Forming apparatus damage can not freeze, poor reliability.
Second is freezed using the refrigeration unit of air cooled condenser, such as air-cooled screw machine, wind-cooling vortex machine.Using
The refrigeration unit refrigeration of air cooled condenser, though without preventing freeze in winter problem, its defect is Energy Efficiency Ratio（COP）Low, freeze energy
Consumption is far above with cold water chiller（With reference to GB50189-2005《Public building energy design standard》5.4.5 bar provides, specified
Operating mode water chiller COP with the conditions of is 3.8~5.1, and air-cooled unit COP is only 2.4~2.8）, the refrigeration unit whole year is poorly efficient
Operation, energy-saving effect extreme difference.
Therefore, being badly in need of exploitation one kind will not can freeze at low ambient temperatures, and double condensations of annual high energy efficiency operation
Device formula refrigeration unit.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of double-condenser formula refrigeration unit, the utility model energy
It is enough not freeze at low ambient temperatures, annual high energy efficiency operation.
Double-condenser formula refrigeration unit of the present utility model, including compressor, air cooled condenser, expansion valve and evaporation
Device, the compressor, air cooled condenser, expansion valve, evaporator are sequentially connected in series to form refrigerating circuit by refrigerant line, institute
The refrigerant line stated between compressor and air cooled condenser is provided with water cooled condenser component；The water cooled condenser
Component includes being coated at the cooling jacket of the refrigerant line and the water pump of recirculated cooling water is poured into the cooling jacket；
Double helix cooling water flow conduits are formed between the cooling jacket inwall and refrigerant line outer wall；
Further, the water pump is provided with two and corresponds two helical flow paths to the double helix cooling water flow conduits
Cooling water supply；
Further, the air cooled condenser includes housing, the condenser coil being arranged in housing and for described
The blower fan that condenser coil is cooled down；The condenser coil outer wall is provided with radiating gear piece；
Further, it is in series with device for drying and filtering on the pipeline between the condenser and expansion valve；
Further, the radiating gear piece is helical form gear piece；
Further, the air cooled condenser also includes being used for the nozzle for spraying water smoke to the condenser coil.
The beneficial effects of the utility model：Double-condenser formula refrigeration unit of the present utility model, make condenser realize the winter,
The automatic control pattern of summer operation conversion, first, during cooling in summer, it is filled with by water pump into the dual-spiral sprue of cooling jacket cold
But water, cooling water is made to be circulated in runner, meanwhile, cooling water is radiated using radiator, so works as outdoor temperature
During higher than 5 DEG C, refrigeration unit is in the high energy efficiency state mainly by water cooling refrigeration, realizes energy-conservation purpose.Secondly, winter works as room
When outer temperature is less than 5 DEG C, refrigeration unit stops leaning on the air-cooled refrigeration of air cooled condenser to water jacket cooling water supply, refrigeration unit,
The condenser of guarantee refrigeration unit, in dry type, air-cooled state, fundamentally thoroughly solves refrigeration in low ambient temperature
The problem of unit outdoor unit freezes.Further, since now outdoor temperature is low, the heat transfer temperature difference of condenser and air is big, heat exchange effect
Rate is high, and refrigeration unit is fully shifted and make use of the cold in outdoor cold wind by condenser.Reach the effect of dual-use,
Water evaporation for cooling unit eer height had so both been remained, the advantages of energy saving in running, air cooling chiller group has been realized again and is not afraid of knot
The advantages of jelly, securely and reliably, the outdoor temperature difference is taken full advantage of, it is energy-efficient.
