accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural principle schematic diagram.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Consult shown in Fig. 1, the air-cooled air-cooler of the relevant integral type environmental protection of the utility model refrigerant, comprises that refrigeration system 1, wind system 2, two systems combine, and shape is in aggregates.Refrigeration system 1 comprises compressor 11, finned cooler 12, finned evaporator 13, heating power expansion valve 14, the refrigerant that compressor 11 is exported arrives finned evaporator 13 successively after finned cooler 12, heating power expansion valve 14, and the refrigerant that finned evaporator 13 is exported is got back to compressor 11 after gas-liquid separator 15; At compressor 11 outputs, be provided with a bypass line 16, bypass line 16 is parallel with finned cooler 12, and bypass solenoid valve 17 is installed on bypass line 16, and bypass line 16 other ends converge the output that is docked with heating power expansion valve 14; Described wind system 2 comprises centrifugal blower 21, induced duct 22 and ajutage 23, and the input of centrifugal blower 21 is connected with the outlet air end of finned evaporator 13 by induced duct 22, and the output of centrifugal blower 21 is linked client 24 by ajutage 23.The external setting of centrifugal blower 21, can place according to client's instructions for use, easy for installation.
In the present embodiment, described bypass solenoid valve 17 is opened or closes according to the leaving air temp control of wind system 2; Between described finned cooler 12 and heating power expansion valve 14, be provided with filter 18, filter 18 filters, deacidifies.Described refrigeration system 1 is moved environmental protection refrigerant R410A, reduces water as cooling media, simplifies machine construction, reduces machine regular maintenance difficulty, reaches energy-saving and environmental protection effect.
During work, as shown in Figure 1, the flow process of refrigeration system 1: through gas-liquid separator 15, unevaporated liquid coolant is separated from finned evaporator 13 gas-liquid mixed refrigerant out, gaseous coolant enters compressor 11 and compresses, form HTHP gaseous coolant, enter subsequently finned cooler 12, by condenser fan 19, drive Air Flow by refrigerant and air generation heat exchange and cooling, form the highly pressurised liquid refrigerant of normal temperature; After filtering, deacidify by filter 18, by heating power expansion valve 14, distribute suitable flow to finned evaporator 13 again, refrigerant is in finned evaporator 13 the insides and air generation heat exchange, absorb air heat and the gasification that heats up, after gas-liquid separator 15 separates, come back to compressor 11 again and compress, so circulation.The flow process of wind system 2: be connected on centrifugal blower 21 by induced duct 22 through the cooled air of finned evaporator 13, then by ajutage 23, centrifugal blower 21 and client 24 coupled together, cold wind after treatment is transported to client and uses.In the course of work, the unlatching of the numerical value that the bypass solenoid valve 17 on bypass line 16 feeds back according to leaving air temp temperature-sensing probe and the poor duty control solenoid valve of setting value or close, temperature-controlled precision can be controlled at thus ± 1 ℃, also avoid high frequent to start simultaneously.
