General: Furnish and install prefabricated, sectional, all-metal clad, modular, controlled temperature rooms that are designed for fie
9、ld assembly, to establish temperature specified within two hours, and to maintain that temperature without further attention. B. Case: Include modular panels for walls, floor, ceiling, and door(s). 1. Panel Construction: Double-wall construction, prewired, and insulated and vapor-sealed sections mec
10、hanically locked in place from interior of room without the use of special tools. Each panel passes through a 1829 mm (6 feet) wide corridor and 813 by 2032 mm (32 by 80 inch) doorway. Panel construction does not incorporate wood. 2. Door: a. Not less than 864 mm (34 inches) wide by 1905 mm (75 inch
11、es) high; construction matching that of panels; with observation panel of sealed multipane glass not less than 305 mm (12 inches) square. b. Door handle and latch permits exterior locking with safety release to allow door to be opened from inside when locked on outside. Safety release will not distu
12、rb vapor seal when operated nor require tools to reactivate. c. Equip door jambs of rooms capable of attaining a temperature of 4 degrees C (39 degrees F) or colder with concealed heater to prevent frost formation or condensation.

13、without license from IHS-,-,-11-11 13 21 29 - 3 3. Access Ports: Equip units with PVC or neoprene sleeves or gaskets for service entrances. Vapor seal access ports at interior and exterior of panels. 4. Finishes: a. Interior Walls and Ceiling: Chemical-resistant nontoxic odorless epoxy, not less tha
14、n 0.0254 mm (1 mil) thick. b. Exterior: Baked enamel or matching interior. 5. Pressure Relief Port: Equip freezers that will operate at minus 18 degrees C (0 degrees F), or lower with 2-way type ports that allow for an increase or decrease of air pressure on the interior of the freezer to equalize w
15、ith air pressure on the exterior. C. Condensing Units: 1. / Air-cooled / Water-cooled / Combination air-/water-cooled / type. Do not locate compressors on top of refrigerator or freezers. 2. Provide positive oil lubrication and oil-level indicating device for each compressor. Equip water-cooled unit
16、s with water regulating valve. 3. Pressure Switches: Automatic-reset low-pressure switch, and automatic- or manual-reset high-pressure cutout. D. Controls: 1. Mount regulating and indicating devices in console or panel adjacent to and no higher than door. Calibrate controls, thermometer, and recorde
17、r in increments of 1 degree C (1.8 degrees F). 2. Operating Temperature Control: Self-contained remote bulb, liquid filled, reverse acting, adjustable, and sealed mercury-bulb-type thermostat, with three-degree differential. /Rooms specified to maintain single temperature do not have temperature sel
18、ection adjustable by operator./ /3. Humidity: Electric control capable of maintaining selected relative humidity within plus or minus 5 percent./ 4. Alarm and Override Temperature Control: Equip with sensing devices and circuits that take over control, initiate corrective action, and activate an aud
19、ible signal device in event of temperature variation in room of more than 3 degrees C (5 degrees F) from set temperature. Signal automatically resets on return of room to set operating temperature. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-11-1
