How Different Types of Chillers Meet the Cooling Demand of Industries?
Chiller is known as significant cooling equipment used in laboratories. The main purpose of a chiller is to remove heat from one area and pass it to sources like ambient air or water. Chiller is compressor based equipment which cools as well as controls the temperature of a liquid. It does not act like air conditioners that cool air. Besides compressor, the other components of a chiller include a reservoir, a temperature controller and a recirculating pump.
Types of Chillers Based on Functionality
Chillers can be segregated on various basis like functionally and portability. They can air chiller, water chiller or screw chiller. Let's learn about the chillers that are classified on the basis of their functioning.
The first type of chiller is Air-cooled chiller which absorbs heat from process water. Then they transfer it to the ambient air. These are widely used in a variety of applications where the heat is discharged. They don't require a cooling tower or even a condensed water pump. The maintenance of these types of chillers is far less than water cooled units. Relying on the fact, they consume 10% more power.
The second type is known as water cooled chillers. Here the heat is absorbed from process water which then is transferred to an individual water source like a pond, river or a cooling tower, etc. These are mainly used in the areas where the heat produced by air chillers creates a problem. As they consume less power, these are preferred by people who are looking for optimum efficiently of power consumption.
Working Process of Chillers
The functioning principle of a laboratory chiller is simple. The reservoir is filled with a liquid or fluid, water or water mix, to be recirculated. Then the reservoir is linked to the equipment required and then the power is transferred to the chiller. The functions of water chillers are regulated by the controller. Individual users can always set the parameters depending on their requirements like flow, temperature, and pressure. An internal strainer is specially used in the process which helps to keep away the harmful particles from the system.
Applications of Chillers in Varied Industries
Different types of cooling equipment are used in varied industries. However, let's talk about the most common applications of chillers.
In plastic industry, Chillers are basically used to cool the hot plastic. It cools down the plastic which is either injected or blown extruded. They also play an important role in cooling down the equipment that is used in the manufacturing process.
When it comes to their role in the printing industry, chillers are used for removing the heat which is generated by the printing rollers. They also support cooling the paper once it comes out of the ink drying ovens.
Modern screw chillers are used in the high powered electronics. The chillers are also used inside the MRI machines and PET, used in the sophisticated diagnostic tools. Chillers are efficient in cooling down the lasers and the source of the power supply which is used to power them.
