These same basic components may be used in the design of a vacuum or a subatmospheric system. The vacuum heating pump maintains a vacuum in the return piping under all operating conditions, assisting the supply steam in overcoming the resistance of the system piping and assuring rapid and uniform steam distribution. 2, record 1, English, - vacuum%20pump
Record number: 1, Textual support number: 2 CONT
Vacuum pumps are used on a system where the returns are under a vacuum. The assembly consists of a receiver, separating tank and automatic controls for discharging the condensate to the boiler. Vacuum pumps are sized in the same manner as condensate pumps for a delivery of 2.5 to 3 times the design condensing rate. 2, record 1, English, - vacuum%20pump

Chauffage à pression sous-atmosphérique. [...] Les pompes à vide sont de deux sortes : 1. les pompes à piston, activées par la vapeur, aspirantes et foulantes, et, 2. les pompes centrifuges accouplées directement à un moteur électrique. 2, record 1, French, - pompe%20%C3%A0%20vide

Chauffage à vapeur sous vide. Une pompe à vide permet d'obtenir dans l'installation une pression inférieure à la pression atmosphérique [...] Le vide est parfois réalisé à l'aide d'une pompe refoulant l'eau condensée dans la chaudière et munie d'un système d'injecteurs appropriés [...] 3, record 1, French, - pompe%20%C3%A0%20vide
Record number: 1, Textual support number: 3 CONT
Pour les grands édifices [...] il est difficile de placer tous les échangeurs de chaleur au-dessus du niveau d'eau du générateur ou de la tuyauterie de retour. On utilise dans ce cas une pompe à vide qui maintient une pression inférieure à la pression atmosphérique (jusqu'à 650 mm de Hg) dans la tuyauterie générale de retour [...] 4, record 1, French, - pompe%20%C3%A0%20vide

A system which regulates steam flow into the main throttle valve under automatic thermostatic control and maintains a fixed vacuum differential between supply and return by means of a differential controller and a vacuum pump. 1, record 2, English, - subatmospheric%20heating%20system
Record number: 2, Textual support number: 1 CONT
Subatmospheric systems are similar to vacuum systems, but in contrast provide a means of partial vacuum control on both the supply and return piping so that the steam temperature can be regulated to vary the heat emission from the heat exchanger in direct proportion to the heat loss from the structure. 4, record 2, English, - subatmospheric%20heating%20system

Dans les chauffages à vapeur, le fluide véhiculaire utilisé est la vapeur d'eau. La vapeur produite dans les chaudières est conduite jusqu'aux corps de chauffe par un réseau de canalisations, s'y condense en cédant sa chaleur latente de vaporisation et retourne sous forme d'eau aux chaudières, à partir desquelles le cycle recommence.
