Why does coolant expand?
As engine coolant heats up it expands, causing a buildup of pressure. During normal operation, the coolant level in the container varies between the cold and hot lines.
What are the different types of absorption cooling?
Many types of absorption cooling systems are available, including lithium bromide/water chillers, which are suitable for space cooling, and ammonia/water systems, which can provide industrial cooling to as low as −50°C (ASHRAE, 2006).

How are thermal expansion estimates performed by CSB?
The thermal expansion estimates were performed using SuperChems Expert™, version 8.3, a component of Process Safety Office®. The starting temperature, pressure, and volume (-42 F, 480 psig, and 0.51ft3) provided by the CSB indicated that these initial conditions are both in the
What are thermal expansion estimates for natural gas liquids?
1 Thermal Expansion of Natural Gas Liquids (NGL) ioMosaic Corporation was retained by the U.S. Chemical Safety Board (CSB) to perform detailed thermal expansion estimates of two NGL compositions. The molar compositions are shown in Table 1. 1.1 Thermal Expansion Estimates
Where does the coolant go in an expansion tank?
Therefore, instead of only containing expanded coolant, the expansion tank is actually a part of the complete cooling system and coolant circulates through the tank as it does through the radiator. It’s typically the highest point in the cooling system.
Can a radiator be used as an expansion tank?
If an expansion tank is overfilled it will discharge coolant when the system is at operating temperature. An expansion tank can also be used as a fill point for the system. When an expansion tank is used the radiator doesn’t require a pressure relieving cap.
Which is the highest point in the coolant system?
An expansion tank can easily be recognized by the neck and cap used. Since the tank is under pressure it will require a pressure rated cap and neck, (Shown right). The pressure relief in the expansion tank should be the highest point in your coolant system.
Why are overflow tanks added to cooling systems?
Overflow tanks were added to cooling systems to catch the overflow and store it, instead of leaving it on the ground. This was good for radiators, and much better for our environment.
