Thermal expansion li qub tau muab faib ua hom sib npaug sab hauv thiab sab nraud yam sib npaug raws li kev sib txawv sib txawv; Sab nraud tshuav hom thermal expansion li qub tau muab faib ua ob hom qauv: F hom thiab H hom.
1) Cov qauv thiab txoj hauv kev ua haujlwm ntawm kev sib npaug Danfoss DANFOSS expansion valve:
Daim duab qauv ntawm qhov sib npaug F-hom thermal expansion valve. Lub hnab ntim qhov ntsuas kub tau ntim nrog cov tub yees thiab muab tso rau ntawm qhov hluav taws xob ntawm cov evaporator. Lub hnab ntsuas kub thiab qhov siab ntawm lub diaphragm txuas nrog lub raj capillary kom paub qhov kub ntawm cov tub yees ntawm lub qhov hluav taws xob evaporator, thiab cov evaporator inlet siab xav tau nyob rau hauv lub diaphragm. Yog hais tias lub load ntawm lub tshuab cua txias nce thiab hydraulic refrigerant evaporates nyob rau hauv lub evaporator ua ntej ntawm lub sij hawm, qhov kub ntawm lub refrigerant ntawm lub qhov hluav taws xob evaporator yuav nce, lub siab ntawm lub diaphragm yuav nce, thiab lub valve qia yuav raug thawb mus rau. nce qhov qhib ntawm lub expansion valve. Thaum lub refrigerant flow rate nce, lub peev xwm txias nce; Yog tias lub tshuab cua txias qis, qhov kub ntawm cov tub yees ntawm qhov hluav taws xob ntawm lub evaporator txo, thiab tib lub hauv paus ntsiab lus ntawm kev ua kom lub valve qhib txo, yog li tswj cov tub yees txaus.
2) Cov qauv thiab lub hauv paus ntsiab lus ua haujlwm ntawm kev sib npaug Danfoss DANFOSS expansion valve:
Lub hauv paus ntsiab lus ntawm qhov sib npaug ntawm qhov sib npaug sab nraud yog qhov pib zoo ib yam li ntawm qhov sib npaug ntawm qhov sib npaug ntawm lub valve, qhov sib txawv yog tias lub siab xav tau nyob rau hauv lub diaphragm ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug yog qhov nkag siab ntawm lub evaporator; Thaum uas xav tias nyob rau hauv lub diaphragm ntawm lub sab nraud balanced expansion valve yog lub evaporator Qhov hluav taws xob siab.
3) H-hom expansion valve
H-hom thermal expansion valve muaj plaub qhov chaw nres nkoj txuas nrog lub tub yees, ob qho tib si zoo ib yam li cov thermal expansion li qub, ib qho txuas nrog cov kua cia ziab, ib qho txuas nrog cov evaporator inlet; Lwm ob qhov chaw nres nkoj, ib qho txuas nrog lub qhov hluav taws xob evaporator, ib qho txuas lub compressor inlet. Qhov ntsuas kub ntsuas qhov muag yog ncaj qha rau hauv lub tub yees cua ntws ntawm qhov hluav taws xob ntawm lub evaporator. Vim hais tias lub expansion valve tshem tawm qhov kub thiab txias qhov muag teev, capillary thiab sab nraud sib npaug sib txuas cov yeeb nkab hauv F-hom thermal expansion valve, kev hloov rhiab heev yog txhim kho, cov qauv yog compact, thiab kev co kuj yog txhim khu kev qha.
