5. DESCRIPCIÓN DE COMPONENTES 5.1 EQUIPO DE REFRIGERACIÓN It consists of the following components: - Compressor. - Condenser. Air or water. - Evaporator. Vertical tube with cooling jacket. They are kept filled with water and, inside, a worm screw scrapes and removes the ice that forms. - Thermostatic expansion valve (capillary in smaller models). -
Page 17: Hydraulic Equipment
5.2 HYDRAULIC EQUIPMENT • Water inlet valve. Controlled by the control board; supplies water from the tank. • Water tank/basin. Maintains the water level inside the evaporator using the communicating vessels principle. Stainless steel electrodes signal the control board to maintain the internal level. An overflow allows drainage to prevent internal spillage in case of malfunction and serves as a drain plug for the tank. -
