The great majority of heat pumps work on the principle of the vapour compression cycle. The main components in such a heat pump system are the compressor, the expansion valve and two heat exchangers referred to as evaporator and condenser. The components are connected to form a closed circuit ... A volatile liquid, known as the working fluid or refrigerant, circulates through the four components. In the evaporator the temperature of the liquid working fluid is kept lower than the temperature of the heat source, causing heat to flow from the heat source to the liquid, and the working fluid evaporates. Vapour from the evaporator is compressed to a higher pressure and temperature. The hot vapour then enters the condenser, where it condenses and gives off useful heat. Finally, the high-pressure working fluid is expanded to the evaporator pressure and temperature in the expansion valve. The working fluid is returned to its original state and once again enters the evaporator. The compressor is usually driven by an electric motor and sometimes by a combustion engine.  4, fiche 2, Anglais, - vapor%20compression%20heat%20pump

Vapor Hand Pump Extinguisher - USES: Flammable liquids and electrical fires. - This extinguisher can be used either indoors or outdoors. The use of this type of extinguisher is not always advisable because of the accumulation of fumes after use. Common sense must be exercised when locating this type of extinguisher. Because they will not freeze, they make a good all around extinguisher and can be easily adapted on field equipment. To use, simply turn the handle and pump, and a 25 to 30 foot stream will be expelled at any angle.  1, fiche 3, Anglais, - vapor%20hand%20pump%20extinguisher

Seau-pompe manuel - UTILISATION : Liquides inflammables et feux de nature électrique - L'emploi de ce type d'extincteur n'est pas toujours recommandé en raison de l'accumulation possible de fumées après l'utilisation. On devra par conséquent faire preuve de jugement dans le choix de l'endroit où l'extincteur sera placé. Comme ces extincteur ne gèlent pas, ils sont polyvalents et peuvent être facilement adaptés à la situation. Pour utiliser l'extincteur, il suffit de tourner la poignée et de pomper, ce qui projete un jet ayant une portée de 25 à 30 pieds, que l'on peut orienter à l'angle voulu.  1, fiche 3, Français, - seau%2Dpompe%20manuel
