Description
Technical field:
The utility model relates to a kind of refrigerating device structure, particularly a kind of refrigerating device structure of carbon dioxide as cold-producing medium that adopt.
Background technology:
Due to the critical-temperature of carbon dioxide low (31.1 DEG C), the refrigerating plant that carbon dioxide is cold-producing medium at normal temperatures higher than critical-temperature, can be imbedded underground for fear of carbon dioxide coolant temperature by condenser.Utilize underground normal temperature not higher than the feature of co 2 liquefaction critical-temperature (31.1 degrees Celsius), the heat of condenser is transmitted to below ground, high-pressure refrigerant carbon dioxide enters into and is installed on underground condenser, after release heat, be condensed into the carbon dioxide liquid of high pressure, carbon dioxide coolant is condensed into after liquid, enter into evaporimeter and become again carbon dioxide again, freezer is freezed.But owing to being installed on, the temperature of carbon dioxide coolant liquid in underground condenser is higher, causes the refrigerating efficiency of refrigerating plant not high.
Goal of the invention:
The purpose of this utility model is just to provide a kind of carbon dioxide refrigeration apparatus structure, above carbon dioxide refrigeration apparatus structure is improved, thereby reach the object that refrigerating efficiency is high.
Summary of the invention:
For achieving the above object, the utility model is taked following design: this carbon dioxide refrigeration apparatus structure, by carbon-dioxide gas compressor, evaporimeter, choke valve, condenser composition, described carbon-dioxide gas compressor exhaust outlet is connected to described condenser, the described choke valve port of export connects described evaporimeter, the described evaporimeter other end connects described carbon-dioxide gas compressor air inlet, described evaporator is in freezer body, by described condenser device underground, by ball-cock assembly and liquid storage tank device between described condenser and described choke valve, described condensator outlet end is connected to the lower inlet of described ball-cock assembly, the lower outlet of described ball-cock assembly is connected to the lower inlet of described fluid reservoir, the lower outlet of described fluid reservoir is connected to described choke valve arrival end, described fluid reservoir top is provided with blow vent, and described fluid reservoir top blow vent is connected with described carbon-dioxide gas compressor air inlet by choke valve.
Because the utility model adopts above technical scheme, utilize or regulate the choke valve between fluid reservoir top blow vent and carbon-dioxide gas compressor air inlet, reduce fluid reservoir upper gas pressure, produce shwoot effect, thereby greatly reduce fluid reservoir inner refrigerant fluid temperature, reach cold function, improved refrigerating efficiency.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation
Detailed description of the invention:
As shown in Figure 1, this carbon dioxide refrigeration apparatus structure of the utility model, by carbon-dioxide gas compressor 1, evaporimeter 2, choke valve 3, condenser 4 forms, described carbon-dioxide gas compressor 1 exhaust outlet 5 is connected to described condenser 4, described choke valve 3 ports of export connect described evaporimeter 2, described evaporimeter 2 other ends connect described carbon-dioxide gas compressor 1 air inlet 7, described evaporimeter 2 installs in freezer 8 bodies, described condenser 4 is installed underground, ball-cock assembly 11 and fluid reservoir 12 are installed between described condenser 4 and described choke valve 3, described condenser 4 ports of export 6 are connected to the lower inlet 13 of described ball-cock assembly 11, the lower outlet 14 of described ball-cock assembly 11 is connected to the lower inlet 15 of described fluid reservoir 12, the lower outlet 16 of described fluid reservoir 12 is connected to described choke valve 3 arrival ends, described fluid reservoir 12 tops are provided with blow vent 18, and described fluid reservoir 12 top blow vents 18 are connected with described carbon-dioxide gas compressor 1 air inlet 7 by choke valve 17.
Because the utility model adopts above technical scheme, utilize or regulate the choke valve 17 between fluid reservoir 12 top blow vents 18 and carbon-dioxide gas compressor 1 air inlet 7, reduce fluid reservoir 12 upper gas pressure, produce shwoot effect, thereby greatly reduce fluid reservoir 12 inner refrigerant fluid temperatures, reach cold function, improved refrigerating efficiency.
