Existing chilled water systems experience several issues that prevent the system from reaching maximum efficiency and meeting anticipated performance. This includes low chilled water temperature difference, also known as low delta T syndrome, which negatively impacts central water plant capacity and chiller efficiency. Additionally, load changes can prevent the chilled water system from meeting the necessary load.
To remedy these problems that prevent existing chilled water systems from achieving maximum efficiency, specifically low delta T syndrome, the design of existing chilled water systems can be modified. These modifications can allow the new system to achieve maximum system efficiency, decreased energy costs, and allow the new system to meet the necessary load.
Dr. Nassif has invented a new chilled water system that can either be retrofitted to an existing system or installed as a new system. This system reduces the size and overall cost of a chilled water system and allows for improved delta T to achieve maximum capacity from the chiller. Additionally, it can take advantage of existing coils and loops for both heating and cooling to increase the heat exchanger surface. Finally, the new system’s configuration will allow for less resistance and pump power.
