What is a Chiller?
A chiller is a device that can cool liquid down through removing the heating energy within them. It removes the heating energy through a vapor-compression or absorption refrigeration cycle. The chilling function of a chiller gets achieved through the transformation of circulating liquid from liquid to gas, which is a absorption process of heating energy.
What does a Chiller Do in a Rotary Evaporator System?
In a rotary evaporator system, a chiller plays an essential role, which means to provide cooling energy for the condenser, in order to get gas-phase substances cooled into liquid-phase.
During the working process of rotary evaporator system, the target substances will be transferred into condenser tube after they get evaporated in evaporation flask. And in the condenser tube, the gas-phase target substances will get cooled down into liquid-phase substances by the cooling energy from a chiller. It is convenient for users to collect liquid-phase substances instead of gas-phase substances.
Working Principle of a Chiller
The working principle of a chiller is to remove the heating energy through a vapor-compression or absorption refrigeration cycle. Coolant is very important in a chiller system, because the circulation of the coolant makes the chilling function. The chiller works through a vapor mechanical compression refrigeration system, which is connected to the process water system through a device called an evaporator. The refrigerant circulates through the evaporator, compressor, condenser and expansion device of the cooler.
Usages of a Chiller
A chiller can be widely used in many fields, including industrial field, chemical field, construction field, people’s life and so on.
In industrial field, a chiller can provide cooling energy for the working system to help the working processes. It is usually used as a part of a whole system. In chemical field, a chiller always is the cold source to provide cooling energy for some experiments.
Types of Chillers
There are mainly two types of chillers, including water cooled chiller and air cooled chiller. These two different chillers have different working principles.
The water cooled chillers works through the movement of water, while the air cooled chillers works through the movement of air. What’s more, the working principles of these two types of chillers are totally different, and they are suitable for different situations, which means they have different applications.
