Common Chiller Problems and How to Deal with Them

Common Chiller Problems and How to Deal with Them

It is not uncommon for people to schedule regular maintenance for their chillers. But, despite the maintenance and repairs, the efficiency of your chillers can decrease with time. A decrease in the chiller’s efficiency can occur for a number of reasons. Leaking refrigerant, clogged process lines, and failed pumps are just some the reasons why this problem takes place.

Here are some common chiller problems and the ways they can be taken care of.

Ciller Not Powering Up

Not powering up is one of the biggest problems with a chiller. This happens for a variety of reasons, some of them are mentioned below.

·         Power switch is turned off.

·         The connections are loose and the line voltage is improper.

·         Phases are not connected properly.

·         Fuse or circuit breaker is blown up.

Insufficient Flow of Fluid and Pumping

Here are some of the reasons why this problem occurs.

·         Fluctuation in the line voltage.

·         Insufficient amount of fluid in the reservoir.

·         Process line in pinched or restricted.

·         Process valve is partially closed.

·         Blocking of the filer fluid.

·         Coolant fluid does not match the temperature requirements.

·         Small size of the process piping.

·         Pump fails.

·         Restriction to the process.

Insufficient Coolant

Let’s take a look at some of the causes behind this problem.

·         Icing up of the evaporator.

·         Temperature is high.

·         Leaking refrigerant.

·         Deterioration in the heat transfer properties of the coolant.

·         Air filer or the condenser gets clogged.

·         Fluctuation in the line voltage.

Now that you have understood the common chiller problems and the causes behind them, let’s shed some light upon the ways these problems can be taken care of.

·         The best way to deal with such problems is to make sure that the chiller is running. The chiller might stop running due to loose wiring, a circuit or fuse that is blown up, or simply the power switch that has been turned off. Most of the times, the power switch is merely turned off, which results in confusions.

·         Make sure that the evaporator is not iced up and the chiller is cooling. In order to do so, the temperature of the coolant must be checked at the outlet of the chiller to the process. If the temperature is not up to the necessary requirements, it is a sign that the evaporator has been iced up. Another reason could be deterioration in the heat transfer properties of the coolant.

·         Make sure that the pump is in a running condition. A valve that is partially closed, pump failure or insufficient amount of coolant might be the hindrances in the proper flow of liquid through the process coolant loop.

·         Keep an eye on the environmental conditions. Extreme weather conditions are one of the major reasons why a chiller fails to perform efficiently. Another reason why the chiller fails to perform is its relocation. Absence of insulation on the piping and line voltage fluctuation also keep the chiller from working efficiently.
