Due to friction, machines that have moving parts are susceptible to breakage from overheating. In this case, they require cooling systems that use water to prevent them from overheating. There are several types of water cooling flower meters, each having its pros and cons. This article will look into some of these coolant flow meters to determine how they work to prevent machines from overheating. Continue reading to be well informed before making a buying decision.
Types of Coolant Flow Meters
There are several types of cooling systems that are used in various machines and industries to prevent breakage from overheating:
Closed-loop Dry Cooling Flow Meter with Trim Cooling
The added supplement in these coolant flow meters makes them different from the closed-loop dry system. During summer, where the dry bulb is too high, these flow meters can achieve proper coolant temperature. Heat is reduced to the required setpoint using an additional liquid-to-liquid trim cooler that uses a water source. This is quite resourceful and cost-effective since it reduces overreliance on city water which is quite costly. Wasted water which is supposed to be disposed of is also reduced, making this type of water coolant flow system quite reliable.
Liquid-to-Liquid Cooling Flow Meters
Of all the water cooling systems, the liquid-to-liquid cooling flow meter has the simplest design. This type of cooling flow meter uses well water when cooling the compressor. If there is plenty of well water lying around, this is the perfect coolant flow meter to use. The compressor is cooled using an intermediate heat exchanger from the other side of the well water. Water and glycol are used as coolants on the other side. Fouling in the heat exchanger is not caused when heat is exchanged from the IH exchanger.
On the well water, side is where fouling of the heat exchanger takes place. The heat exchanger can be taken apart for cleaning by the operator. First, however, the heat exchanger has to be picked properly. Plate and frame or tube and shell are the widely used HI exchanger.
Usually, a coolant temperature of 5° above the plant cooling “water” is achievable with the liquid-to-liquid cooling flow meter. The L to L flow meter supplies a 60° F coolant to the load and well water 55° F. This water cooling flow meter is also cheaper to install and use than other types of water cooling systems. Since it can be installed outside or inside the plant, it is also quite flexible.
Closed-Loop Dry Cooling Flow Meter
The working principle that this type of flow meter uses is the same as that of a car radiator. Heat is transferred in this type of flow meter using an air-cooled fluid cooler pumped through rows of finned tubes. There are other support components found in this type of coolant flow meter that helps with the cooling process. These components include the piping system, the fan, control skid and pump, and the fluid cooler. Ambient air is set up outside to reject heat.
The ambient dry bulb temperatures can reach ° F to 10° F when using this type of flow cooling flow meter. A closed-loop dry cooling flow meter is cost-effective since the only components that use energy are the fluid cooler fans and the coolant pump. Thermostats are put in place to prevent overcooling or undercooling. These thermostats are used to regulate the fluid’s cooling temperature.
Constant cleaning of the fluid cooler is necessary since the environment where it operates is usually dirty. Due to wood, seeds, dirt, debris, and wood, fouling is bound. What makes this type of cooling flow meter reliable is that it is easy to install and maintain.
Conclusion
Coolant flow meters are essential devices used to prevent machine damage that comes from overheating. Cooling systems regulate the surrounding temperature of equipment to ensure that they function at optimum levels. Before purchasing water cooling flow meters, ensure you do proper research first to avoid future problems.
