The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator.

Thermal bulp kaisey gas k saat kaam karta hai

Please help me, maine 2 din pehle ek 1.5 ton 5-star inverter AC khareeda. Installation team aayi aur indoor aur outdoor unit ko perfectly install kiya. Phir unhone system ko charging hose (service line) ke zariye vaccum kiya, aur vaccum complete hone ke baad vaccum motor ka valve band kiya aur motor ko off kiya. Uske baad unhone discharge line (liquid stop valve) ko 5 seconds ke liye khol ke leaks check kiya aur fir band kiya. Yeh sab kuch woh manual ke hisab se bilkul sahi kiya tha. Lekin manual ke according, unko charging hose se vaccum aur gauge ko service port se disconnect karna tha, phir liquid aur gas stop valves ko fully open karna tha. Lekin unhone discharge line ko puri tarah se khol diya aur phir charging hose ko disconnect karna shuru kiya, jis se gauge connected tha. Jaise hi gauge ke charging line (service line) se kholne lage, gas charging hose se leak hona shuru ho gayi aur unhone almost 30 seconds lagaye charging hose ko disconnect karne mein, tab tak woh leak kar rahi thi. Disconnect hone ke baad leak ruk gayi, aur phir unhone discharge line ko fully open kiya. Ab main overthinking kar raha hoon aur darr raha hoon ki woh gas kya thi, kya yeh refrigerant thi ya compressor oil ya phir air compressor mein se kuch ghus gaya hoga. Kyunki system ko vaccum kiya gaya tha, mujhe dar hai ki refrigerant contaminate ho gaya hoga aur compressor blast ho sakta hai. Ab main darr ke maare hoon ki kab blast ho jaye. Ab main kya karoon, please meri madad karo."

Please o baat clear kariye
