Abstract
A liquid system for circulating a liquid through a circulation loop includes a liquid pump, a primary liquid reservoir and an auxiliary liquid reservoir. The liquid pump pressurizes liquid within the circulation loop. The primary liquid reservoir has a primary variable volume expandable to accommodate volumetric expansion of pressurized liquid up to a threshold volume. The auxiliary liquid reservoir has an auxiliary variable volume expandable only after the threshold volume is exceeded up to a maximum volume.
Claims20
A liquid system for circulating a liquid through a circulation loop, the liquid system comprising:
- a liquid pump for pressurizing liquid within the circulation loop;
- a primary liquid reservoir in fluid communication with the circulation loop and having a primary variable volume expandable to accommodate volumetric expansion of pressurized liquid up to a threshold volume;
- and
- an auxiliary liquid reservoir in fluid communication with the circulation loop and having an auxiliary variable volume expandable only after the threshold volume is exceeded up to a maximum volume.
A liquid system comprising:
- a circulation loop;
- a fluid pump configured to pressurize fluid within the circulation loop;
- a primary reservoir in fluid communication with the circulation loop and configured to expand in volume under pressure within the circulation loop up to a threshold pressure;
- and
- an auxiliary reservoir in fluid communication with the circulation loop and configured to expand in volume once the threshold pressure is exceeded.
A method of accommodating expanding fluid in a closed fluid circulation loop, the method comprising:
- circulating pressurized fluid in a closed fluid circulation loop using a pump;
- expanding a volume of a primary reservoir connected to the closed fluid circulation loop up to a threshold volume to accommodate expansion of the pressurized fluid to a threshold level;
- and
- expanding a volume of an auxiliary reservoir connected to the closed fluid circulation loop up to a maximum volume to accommodate expansion of the pressurized fluid from the threshold level to a maximum level.
