Guidelines in Chiller Safety Controls: Things You Need to Know About

27 March 2020

Chillers are essentially a part of the heating, ventilation, and air conditioning (HVAC) systems that dehumidify and cool an entire building. This system has the sole purpose of creating a comfortable interior environment regardless of the conditions external to the building. 

The use of chillers may enhance human comfort, but they can still become a hazard if operated in the wrong way. Believe it or not, some people are still unaware of the safety controls and procedures that should be followed when operating and working around the chillers. 

The Fundamentals of a Chiller System

Most cooling systems rely on refrigerants that change state from time to time. When the refrigerant is in the vapor form, the fluid absorbs the surrounding heat and releases it to another location once it converts to liquid. The physical form of the fluid tells the temperature and pressure of the chiller. It also determines the rate of the conversation that is supposed to take place for the occurrence of a specific cooling effect. Overall, refrigerant can determine the efficiency of the cooling system.

Lack of Proper Use can be Dangerous

Huge chiller systems might contain a high amount of ammonia, one of the oldest but still widely used refrigerant around the world. While it is safe for the environment, ammonia can be dangerous to people’s health. When this refrigerant meets water or any impurity, the piping of your chiller would be obstructed, generating different problems on your whole chiller. Any spill on your system will expose your chiller system to high concentrations of ammonia. Consequently, people working around this system will also be exposed to the refrigerant. People who are exposed to this refrigerant might experience eye irritation, vomiting, breathing problems, skin inflammation, and many more. 

Inclusion of Chiller Safety Controls

Low refrigerant temperature, low oil pressure, or high condensing pressure can affect and even harm your chill system, which is why different safety controls are designed to alleviate the effects of the mentioned elements. One of the controls is capacity controls, which maintain the temperature of the chilled water. Another type of safety control is the refrigerant flow controls, which are set in connection with the compressor used. When these controls fail, the system will be set to shut down to prevent obtaining machine damage and harming the people around it.

Operational Training for Chiller Use

Since the refrigeration system relies heavily on chillers, your employees must know how to handle them with care. Subjecting your employees to a series of operational training will equip them with the necessary knowledge and skills in using and handling modern and traditional cooling systems, especially their safety controls. Under this training, your employees will be taught the fundamentals of operating any type of cooling system. This training can also help them detect and determine any problems on the chiller.

Knowing these things about chillers and their safety controls ensures the safety of your facility and its people or employees. To learn more about chiller safety controls, just contact us Protector Air Care.
