Regarding chiller unit design
Thread Content
I want to design a small cryogenic cooling system that cools only one tank. The coolant temperature is -35 degrees, with a flow rate of around 4 M3/h; the cooling capacity required for the reactor is approximately 20 kW. So, what power rating should the compressor have? What is the compressor’s efficiency? What margin should be taken?
There are many unit options available for you to choose from; it is recommended to use a single-stage, two-stage piston compressor unit (such as Bizter, Copeland...,) with R22 as the refrigerant. The condenser can be air-cooled or water-cooled; the evaporator uses copper tubes for dichloromethane and steel tubes for brine. For compressor units, it is generally advisable to leave a margin in terms of cooling capacity.
Thank you, floor 2. If I want to buy such a small complete set, is it available?
