Cooling system in a laboratory

In these areas, the production of waste heat from compressor-based cooling system is highly undesirable. The partitioned compressor-based cooling system could not have been used for the lack of space. Therefore, a cooling system using cold water from water mains as a refrigerant had been developed. The regulation system regulates the flow rate of cooling water on the basis of the current coldness consumption and entry temperature of the cooling water, and thus significantly decreases the consumption of this water. Units based on this principle and with the output of 20 and 40 kW were installed. These units provide for the cooling of vacuum furnaces and machines for precise working.
