| During step 2, the thermosiphon starts to operate and defrosts the air evaporator. |
| This article presents a heat pump for simultaneous heating and cooling in which a thermosiphon forms to defrost the air evaporator. |
| While any suitable liquid can be used, water is the easiest liquid to use in thermosiphon systems. |
| They depended on forward movement of the car and fans to move enough air through the radiator to provide the temperature differential that caused the thermosiphon circulation. |
| A wick is not needed in a thermosiphon because gravity moves the liquid. |
| If the piping of a thermosiphon resists flow, or excessive heat is applied, the liquid may boil. |
