Chillers are actually devices designed for PROCESS COOLING. When chiller instruments are manufactured for a wide range of industries, including, the research industry. The chiller instruments for laboratories, like any other piece of equipment, must be adapted to the needs of the research work in the laboratory, so you will find a diverse supply of chiller instruments.
How does a chiller work?
Laboratory chillers are instruments that transfer heat from one thing to another. Generally, they use a liquid. Chillers are machines that remove heat from a liquid by vapor-compression or absorption refrigeration. To cool equipment or other process streams, the liquid can then be circulated via a heat exchanger.
Application of Laboratory Chillers:
In labs and medical/research facilities, chillers are used for a number of purposes, such as analytical instruments, linear accelerators, equipment cooling, radiation therapy machines, CT scanners, blood cooling systems, MRI machines, biograph systems, etc.
The reservoir capacity, power needs, and even size constraints of laboratory chillers may be tailored to fulfill particular requirements and standards, such as reservoir volume and power requirements.
Types of chillers-what to choose
The size of a chiller is determined by the amount of heat it can absorb per unit of time. This relies on the thermal properties of the application. Contrary to what is said, calculating the needed size is simple if you know the formula plus a few additional factors.there are a few things you need to know to select the appropriate chiller:
- The flow rate
- The required water temperature
- The temperature of the incoming water
General concepts about chillers:
• Determine Temperature Differential (ΔT°F) T°F = Incoming Water Temperature (°F) – Chill Water Temperature Required
• Calculate BTU/hr. BTU/hr. = Gallons per hr. × 8.33 x ΔT°F
• Evaluate cooling capacity in Tons = BTU / hr. ÷ 12,000
• Increase the size of the chiller by 20%. Ideal Size in Tons = Tons x 1.2
• The size obtained is perfect for your requirements
