Variable speed drives freezer with dual temperature refriger

Variable speed drives freezing function to save a lot of energy and money. Many clean room design and operations staff, there is no need to use variable speed drives freezer, because the load is usually constant, multi-level freezer units typically control for high-load operation. However, the load constant refrigerating machines typically work at full load or less. Variable drive refrigerating machine normally operates in the 90% -95% of full load to conserve energy. 1000 tons freezer stable work at 70% of full load If you are using a variable speed drive, a year would save 20000-30000 U.S. dollars. According to the manufacturer's data, the price of electricity is $ .05 / kilowatt-hour, so the cost can be recovered in about a year.
The multi-level freezer cold water units rarely high-load operation. Usually the case, the on-site load is usually not exactly match the level change of the unit. Many operator to run additional refrigerating machine in order to reliably Once a refrigerating machine malfunction, the other refrigerating machine can be immediately added to replace its entire load, so cold water units frequently is to allow the refrigerating machine in the cooling capacity of 60% to 80 % operation.
Time to buy a new freezer, the specified purchase a variable speed drive the freezers deal. Freezer with a variable speed drive to reduce energy consumption, while allowing the other freezers reliability. There are many studies and experiments show the effect of variable speed drives freezer is good. Two decades, the manufacturers of variable speed drives freezer manufactured reliability products used in new and clean inside the factory upgrade.
????????Freezing systems are usually designed to be able to withstand the maximum load, regardless of the maximum load occurs whether frequent. The chilled water temperature in the refrigeration cycle in the process, by all load only a small portion of the extreme heat load to determine that this is only one or two of the many cases. This will cause the excess of refrigerating capacity, in the case of insufficient load inefficient. When the freezing temperature of the water supplied is low, the work efficiency of the refrigerating machine will be low. On average, the chilled water supply temperature for each additional one degree Fahrenheit freezer efficiency increased by more than one percentage point. If the division of the load, providing chilled water of two different temperatures, so the working efficiency will be higher
