Čia tas ofirice tube a.k.a. tavo vadinamas filtriukas, kaip rašoma, jis galu užsikišt, bet jo pirminė paskirtis ne tokia:
Some vehicles have an orifice tube rather than an expansion valve, but it serves the same purpose in allowing the refrigerant to expand and the pressure to be lowered before the liquid enters the evaporator. The orifice tube allows refrigerant to flow at a constant rate and has no moving parts, but it can become clogged with debris over time. Systems with an orifice tube automatically turn the AC system on and off to regulate the flow of refrigerant to the evaporator.

O čia džiovintuvas, kuris turi būt keičiamas kiekvieno rimtesnio serviso metu
