Subject field(s)
  • Climate-Control Equipment (Motor Vehicles)
CONT

When the engine gets hot, coolant and air in the system expand, causing a pressure buildup. The pressure valve in the radiator cap opens ... and coolant and air flow out through the cap into the coolant-recovery reservoir.

OBS

expansion tank: term officially approved by the Lexicon Project Committee (New Brunswick).

CONT

Quelques constructeurs remplacent la soupape par un vase d'expansion fermé hermétiquement et rempli à mi-hauteur. À chaud, l'eau du radiateur est refoulée dans le vase, le niveau du liquide s'élève en provoquant une augmentation de pression. À froid, la contraction du liquide abaisse le niveau dans le vase d'expansion [...]

Record 4 2011-05-24

English

Subject field(s)
  • Heating
DEF

A tank placed above the boiler of a hot-water system, to allow for the increased volume of water when heated.

CONT

All hot-water heating systems must be provided with an expansion tank of either the open or closed type.

CONT

The expansion tank (also called a compression tank) allows for the expansion of the water in the system as it is heated. It is located above the boiler.

CONT

The compression tank differs from the expansion tank of the obsolete gravity systems in this characteristic of maintaining system pressure. The compression tank is open only to the system water, whereas the gravity expansion tank was open to atmosphere as well as to the system, and consequently had to be located higher than the highest radiator. The compression tank may be located anywhere, although tank size decreases with increasing height above the boiler. In large systems economy may indicate a high position, rather than in the usual boiler-room area.

OBS

Also used in the Heat Transfer Module with heating liquid called Dupont Telar which is a mixture of ethylene glycol with a corrosion inhibitor and distilled water.
