NOTES:

1. THIS DETAIL IS A GENERAL SCHEMATIC TO SHOW THE CHILLER PIPING, VALVES, GAUGES, ETC. REFER TO FLOOR PLANS FOR ACTUAL

CONNECTIONS, ORIENTATION, AND LAYOUT.

2. REPLACE CHILLED WATER AND CONDENSER WATER SUPPLY AND RETURN PIPE, VALVES, & FITTINGS AS SHOWN ON THE FLOOR PLAN.

GROOVED PIPE AND VICTAULIC COUPLINGS SHALL BE USED.

3. CONNECT CHILLER REFRIGERANT RELIEF VALVES TO NEW REFRIGERANT PURGE PIPE. PROVIDE A PIPING FLEXIBLE CONNECTION CLOSE TO

THE CHILLER. PROVIDE A TEE IN THE DISCHARGE PIPING NEAR THE CHILLER WITH A DRAIN VALVE, NIPPLE AND CAP IN THE BOTTOM OF THE

TEE.

4. ALL PIPING SHALL BE CONFIGURED TO MINIMIZE INTERFERENCE WITH THE SERVICE AND MAINTENANCE OF THE CHILLER.

5. PROVIDE AND INSTALL TEMPERATURE AND PRESSURE GAUGES WITH SNUBBERS.

6. FURNISH AND INSTALL FLOW SWITCHES AS INDICATED ON PLANS UNLESS PROVIDED ON THE CHILLER BY THE MANUFACTURER.

7. FURNISH AND INSTALL SENSORS FOR ALL DATA POINTS NOT INCLUDED BY THE CHILLER MANUFACTURER.

8. UTILIZE SUFFICIENT VICTAULIC PIPE COUPLINGS TO ALLOW REMOVAL OF PIPE AND ACCESSORIES TO PERMIT EVAPORATOR AND CONDENSER

TUBE REMOVAL. ALL OTHER PIPE SHALL BE WELDED.

9. MAINTAIN APPROPRIATE CLEARANCES PER MANUFACTURER'S RECOMMENDATION ON PIPING TO ACCOMMODATE ALL VALVES, FLEX

CONNECTIONS, AND PIPE FITTINGS. PERFORM ADDITIONAL PIPE CUTTING IF REQUIRED.

10. REFER TO SPECIFIC CHILLER PLANT DRAWINGS FOR EXACT PIPE SIZES.

MOTOR VEHICLE ADMINISTRATION EMCS SEQUENCES OF OPERATION

FOR THE HEADQUARTERS BUILDING – CHILLER REPLACEMENT

1. The MVA Headquarters building in Glen Burnie MD has an existing building automation system (BAS). The existing BAS is Schneider Electric Eco-Struxture 2.0 Installed in 2019. This project is to replace two of three existing water cooled chillers. Existing pumping systems to remain as is. The existing control systems will be modified as required to provide new control functions. Control functions not affected by these upgrades do not need to be modified.

2. New controls will be the latest version of Schneider Electric Eco-Struxture compatible with the existing system. Contact for current control contractor is:

John Beahm, Sales Operation Manager, Control Sources LLC. Cell: 410.365.6009

Fax: 410.574.6300 Email: jbeahm@controlsources.biz

1. Chilled Water Plant Operating Modes

a. The EMCS shall enable the chilled water plant when the outside air dry-bulb temperature is above 48°F (ADJ) for 30 minutes

(ADJ), and there is a request for cooling.

b. A request for cooling shall be initiated in each AHU when the CHW Valve is 100% open (ADJ) for ten minutes (ADJ), and the discharge air is 2°F (ADJ) above set point for ten minutes (ADJ).

c. A request for cooling shall be cleared when the CHW Valve is 0% open (ADJ) for ten (ADJ) minutes or when the AHU is de-energized.

d. The EMCS shall disable the chilled water plant when the outside air dry-bulb temperature is below 45°F (ADJ) for 60 minutes

(ADJ), or there are no requests for cooling for 60 minutes (ADJ).

e. The OWS shall include provisions to override automatic operation and manually enable or disable chilled water plant operating modes based on a single graphic command.

2. Chiller Lead / Lag Designation Modes

a. The EMCS shall use lead / lag chiller designations to equalize runtime during staging. Chillers shall not be started and stopped for the sole purpose of maintaining equalized runtime.

b. If a chiller failure is detected, that chiller will be removed from the staging sequence until the failure is manually reset at the OWS.

c. The facility operator shall have the provisions to make one or more chillers unavailable to staging sequence for purposes of performing routine maintenance.

d. The OWS graphics shall clearly indicate the calculated staging sequence, as well as any chillers that are either unavailable or need to be reset.

3. Chilled Water Supply Temperature Set Point Modes

a. Chilled water temperature set point shall be reset as follows:

Outdoor Air Temperature Dry-Bulb Chilled Water Set Point

50°F (ADJ) 49°F (ADJ)

85°F (ADJ) 44°F (ADJ)

b. All chillers shall operate at the same chilled water temperature set point, and all chilled water temperatures listed are leaving or supply water temperatures.

4. Chiller Control Modes

a. The EMCS shall enable and disable chillers as required by the chiller staging sequence.

b. The EMCS shall be connected to each respective chiller interface and monitor all chiller operating parameters which are currently connected to the DDC systems in the Headquarters Building. All points will be displayed on the OWS graphics.

c. All factory-furnished interlocks, time delays, and load controls included with the chiller control panel to maintain the integrity of the chiller shall remain intact.

d. The EMCS shall monitor and confirm chiller status through the local chiller controller.

e. If a chiller failure is detected, the EMCS shall initiate an alarm at the OWS,…
