This gas then passes through heat exchanging pipes where it loses most of its heat to its surroundings which causes the cooling of the refrigerant. It then passes through a condenser which causes the gas to get converted into a liquid form. This happens because In this condenser the temperature of the refrigerant keeps on reducing but the pressure remains the same.
