This will produce some cost saving while still benefiting the environment. The next step is clearly to investigate the effects of increasing the load on the CL system and determining the amount of discomfort, if any, the labs will experience due to a change over to a CL system. The first step in investigating the loading on the CL system is to determine exactly how much additional load the CL system can handle. To determine the loading limits of the system is a difficult task. Some specifications of the system may be obtained from the manufacturer and talking to the maintenance personnel will also help.
Information is available from the maintenance and repair companies.
Also Mechanical engineering professors may provide some assistance. Assessing the inconvenience caused to the personnel is also a difficult task. The best way to pursue this would be to create a survey and interview the lab personnel. The inconvenience could be things such as readjustment of equipment to compensate for change in CL water temperature, additional piping, down-time for the retrofit, and pressure requirements if any. If the CL system is capable of handling the proposed loading then an energy analysis needs to be performed to determine what cost will be created by increasing the load on the system.
