PCT No. PCT/NL96/00219 Sec. 371 Date Oct. 13, 1998 Sec. 102(e) Date Oct. 13, 1998 PCT Filed Jun. 3, 1996 PCT Pub. No. WO96/38694 PCT Pub. Date Dec. 5, 1996A method for expansion control in a closed fluid circulation system with varying temperature, in which system air is drawn from the circulating fluid through the formation of an air head wherein air to be withdrawn is collected and from which air can be blown off, controlled by a valve, to the environment or a receiving space, while further off, measures are taken for taking up, when the temperature varies, an attendant expansion and shrinking of the fluid within the closed system, and measures for enabling adding fluid to the system, which fluid is withdrawn from an external stock of fluid under pressure, and the air head volume is measured and when a predetermined value is exceeded, a fluid valve is opened through which fluid is introduced into the air head until the volume of the air head is substantially equal to the predetermined value and the fluid valve is closed.
