Knowledge Base

Q

High cooling capacity and high-power screw cascade refrigeration units are often used in production or experiments. How to choose a high cooling capacity and high-power screw cascade refrigeration unit? How do you know which factory has production experience in producing high-power screw cascade refrigeration units with high refrigeration capacity? May I ask if there are any use cases or contracts.

Q

The refrigeration screw unit is a common equipment in industrial refrigeration systems, and estimating its refrigeration capacity is the key to ensuring its normal operation. This article introduces the calculation methods for the cooling capacity of refrigeration screw units, including mass flow method and energy balance method, and elaborates on how to use these methods to obtain accurate cooling capacity.

Q

The refrigeration coefficient of water-cooled electric screw unit is one of the important parameters for measuring the refrigeration performance of the unit. The coefficient depends on the design of the unit and the operating environment, which affects the efficiency and energy-saving performance of the unit operation.
