A laboratory chiller is an essential laboratory tool that removes heat from a liquid through a vapor condensation or absorption refrigeration cycle. It is interesting to know that this liquid can be circulated through the air heat exchanger and the required equipment.
Laboratory chillers are used for cooling and lowering the temperature in scientific, research and academic purposes. In this article, we explain what a chiller is and what are its types and how they are used in universities, research and scientific centers to cool research samples in closed or open cycle.
What is a laboratory chiller?
A chiller is a laboratory equipment that removes heat from a liquid (usually water) based on the vapor condensation or absorption refrigeration cycle. This liquid can be used for cooling air or devices. The points about the design and selection of chillers include: efficiency, efficiency, maintenance, environmental vulnerabilities.
Types of laboratory chillers
Laboratory chillers are divided into 2 types, compression and absorption. We will examine each of them below:
Compression chiller
A compression chiller is used to cool water so that the cooled water can be used to cool the air in the building or to cool machinery and industrial products.
Absorption chiller
An absorption chiller uses a gas flame. For this reason, these types of chillers are also called gas chillers. An absorption chiller is a device that uses incoming heat (hot water or steam) to produce cold water.
Laboratory chiller components
The laboratory chiller consists of several components, each of which has an important role in its operation system. The most important components of laboratory chillers include:
Laboratory chiller compressor
The compressor is one of the most important components of the chiller, which has various types such as twisting, helical, centrifugal, etc. The existence of this part is due to the fact that it reduces the gas volume and transfers it to the condenser by increasing the temperature and pressure.
Laboratory chiller condenser
Condenser is one of the other components of the chiller, which is usually an air-cooled condenser. The function of this part of the laboratory chiller is to cool the refrigerant and convert it from gas to liquid.
Laboratory chiller expansion valve
The third important part is the expansion valve, which is the location of this valve before the evaporator. The work of the expansion valve is actually the control of the refrigerant.
Laboratory chiller evaporator
Among other important and main components of the laboratory chiller, we can mention its evaporator, whose task is to convert liquid into gas. Laboratory chiller evaporator is mainly plate type.
Laboratory chiller control panel
The difference between the laboratory chiller and other chillers is its high accuracy in controlling the temperature of the cooling water, which can be done with the electrical panel including various components such as PLC or control board, HMI display, switches and protective parts.
Application of laboratory chiller
Laboratory chiller is used in various cases, some of which are mentioned below:
- When we need a chiller and cooling to increase the efficiency of a product, we must first estimate the amount of heat loss of the device and then, according to the obtained results, we buy a laboratory chiller.
- Laboratory chillers are used in universities, research and scientific centers to cool research samples in closed or open cycle.
How laboratory chillers work
Chillers work in 4 stages, which include the following:
-
Refrigeration
To begin cooling, the laboratory chiller must first go through a refrigeration process. This cooling process transfers the heat along with the equipment and finally lowers its temperature.
-
evaporation
After the refrigeration process starts, the heat evaporates with the help of water or air. This evaporation causes water or air to boil and turn into steam.
-
Compression
Once the steam is formed, it reaches a compressor that increases its temperature and pressure.
-
Density
In the last step, the vapor reaches the condenser through the compressor, which once again reduces the temperature and turns the vapor into a liquid.
The difference between a chiller and a circulator
Chillers are not technically the same as circulator, although they are sometimes used interchangeably. In better words, we should say that the circulator is small, works in a wide temperature range and creates high temperature stability. But the chiller is suitable for larger industrial applications and works in a relatively lower temperature range, but you should know that the chiller produces much more heat.
