When the tank is filled with chilled water, each liquid glycol ball turns into ice glycol balls. The phase change makes them storage a huge amount of cooling energy. While transferring the cooling energy from the chillers to the glycol balls, the electricity cost is at the lowest because of the off-peak rate.

The armature is located in the upper part of the valve. A stem passes through the fixed core and is coupled to the seal. This is held off the seal by means of a spring and makes a seal when the coil is energised, thus closing the valve. Three Way Direct Acting Solenoid Valves work in almost the same way as a two way direct acting solenoid valve.

Setting the Temperature: A dial lets you pick the temperature at which the heater turns on or off. Bimetal Strip: The strip is made of two metals (like iron and brass) bolted together. Iron doesn''t get as long as brass when it''s heated, so the strip bends inward when hot. Electrical Circuit: The bimetal strip is part of an electrical path (shown in gray).
