5. PROJECT REQUIREMENTS:

A. Technical Proposals are required to show the new maintainable arrangement for the new compressors with water cooled tube and bundle condensers.

The CONTRACTOR shall do the project in two separate phases, Phase 1 and

Phase 2 as shown on the Temperature Control Rooms 2018-01-30.pdf.

1. Phase one would be for the south rack located in room 301A (6 compressors and associated equipment serving Temperature Control Rooms 142, 143, 154, 154A, 156, and 156A).

mailto:William.Prange@ars.usda.gov mailto:Phil.Smith@ars.usda.gov

2. Phase two is for the remaining rack (5 compressors et al) located in room 301, serving Temperature Control Rooms 131, 206, 223, 224, and 225.

B. The compressors and condensers are to be mounted on a single layer raised “rack” which will be installed to allow for ease of maintenance by positioning the racks away from the walls or other fixed barriers. Housekeeping pads to be installed as needed to support the rack.

C. Contractor is to size the new compressors and evaporator to meet the specified

Control Temperatures.

1. Control Temperatures are to maintain temperatures 1 Celsius of the setpoint, and control accuracy of 0.5 Celsius. Rooms are monitored and controlled by existing Johnson Controls Metasys™ Building Automation

System.

D. Replace existing Evaporator installed in room 131 with unit sized appropriately to room size and temperature requirements. All other evaporators shall be re-used and cleaned as needed with appropriate coil cleaning methods.

E. Replace current evaporator fans with Electrically Commutated Motors (ECM) and controllers.

F. Refrigerant used shall be 507. Existing line sets and evaporators are to be cleaned/ flushed per manufacturer recommendations to remove previous refrigerant oil and contaminants.

G. Rooms with designed working temperatures below freezing shall have KE2

Evaporator Efficiency units installed. (rooms 131, 154, 154A and 225) These units will control defrost and monitor efficiency in rooms and shall report to a central KE2 LDA interface.

H. Install Infrared refrigerant leak detector devices in each room and on compressor racks. These devices shall report to a central monitoring station to alert staff of leaks.

I. Replaceable core inline filter-dryers shall be installed on suction line of all compressors.

J. Isolation valves shall be installed on water lines at appropriate points on each system to allow ease of service and repair.

K. Isolation valves shall be installed on refrigerant lines at evaporator, condenser and compressor.

L. Replace existing room lighting (incandescent or metal halide) with waterproof dimming LED linear fixtures providing 40-50 foot-candles at 3 feet above floor.

M. Testing of installation

1. Charge system with regulated dry nitrogen and the appropriate tracer gas to bring system pressure up to 300 psig minimum. After system has been checked for leaks and all leaks have been repaired and retested, the system must stand, unaltered, for 24 hours with no more than a +/- 1-pound pressure change from 300 psig, using the same gauge.

2. Vacuum test system per refrigeration compressor manufacturer’s recommendation for commissioning. Vacuum test is to be performed in the presence of a Government representative with 200 microns pulled and held for

24 hours. A maximum drift of 100 microns over 24 hours is allowed. See https://www.epa.gov/sites/production/files/documents/leakguidelines.pdf https://www.epa.gov/sites/production/files/documents/leakguidelines.pdf

N. Humidity Control is provided by existing Munters desiccant wheel dehumidifiers.

No modifications to this equipment are covered under this contract.

O. Existing Temperature controlled rooms are constructed with pre-engineered 4” poured-in-place urethane panels (estimated R-28 value).

P. Two access doors allow access into the shaft servicing phase 1 piping connecting the 3rd floor and ground floor walk-in coolers are located at the base of the shaft accessible thru the elevator machine room and at floor level on the third floor.

Q. Condenser water supply Pumps, each rated at 2 horsepower and programmed for lead/lag control), were designed to provide 60 GPM with a 65-foot head. The cooling tower set point is 68°F with an alarm temperature of 80°F.
