VA VHA SAOC 2018 A8CA4E75

QUESTION: The specifications call for digital scroll compressors in Section 23 81 00 (page 4), but the schedule calls for 4 stages of operation. Additionally, the drawing shows NO hot gas bypass lines. Note 1 on the schedule calls for modulating hot gas bypass. But, that is NOT in the spec. If we can use digital scroll, we DO NOT need hot gas bypass.

ANSWER: The condensing unit has dual refrigeration circuits. Each circuit has two scroll compressors. The condensing unit has four capacity stages as stated on the schedule. Condenser modulation is achieved by turning compressors on and off in sequence.

Although the manufacturer offers Hot Gas Bypass as an option, the VA has indicated that Hot Gas Bypass is not needed for the level of control desired for the kitchen operation. Hot Gas Bypass can be added in the future should the need arise. The addition of Hot Gas Bypass would provide more precise control at low capacity.

Consequently, the following addendum to Specification Section 23 09 23 – 23 is issued:

Specification Section 23 09 23 page 23, Paragraph 2.10 Final Control Elements and Operators, Item F. 3., Change to the following.

3. Required control operation.

AIR HANDLING UNIT S-1

DX Coil and Condenser Cycle the four (4) compressors which each have digital control modulation, to maintain the room set point by (resetting the discharge air set point) (allowing the discharge air to float between 50F and 75F adjustable).
