MARINE WATER BOXES

Marine water boxes allow service access for cleaning of the heat exchanger tubes without the need to break the water piping. Bolted-on covers are arranged for con- venient access. Victaulic nozzle connections are stan- dard; flanges are optional. Marine water boxes are avail- able for condenser and/or evaporator.

KNOCK-DOWN SHIPMENT

The chiller can be shipped knocked-down into major assemblies (evaporator, condenser, driveline, etc.) as

required to rig into tight spaces. This is particularly con- venient for existing buildings where equipment room access does not allow rigging a factory packaged chiller.

REFRIGERANT STORAGE/RECYCLING SYSTEM

A refrigerant storage/recycling system is a self-contained package consisting of a refrigerant compressor with oil separator, storage receiver, water-cooled condenser, fil- ter drier and necessary valves and hoses to remove, replace and distill refrigerant. All necessary controls and safety devices are a permanent part of the system. Typi- cally not required if unit isolation valves are provided.

SI Metric Conversion

The following factors can be used to convert from English to the most common Sl Metric values.

Integrated Part Load Value (IPLV)

In the English I-P system, IPLV is calculated by the fol- lowing formula. A full explanation is shown on page 4:

Where: A =

B =

C =

kW / ton at

50% Load @ 65°F ECFT

 

D =

kW / ton at

25% Load @ 65°F ECFT

In SI Metric, the formula is:

IPLV* = 0.01A + 0.42B + 0.45C + 0.12D

Where: A = COP at 100% Load @ 29.4°C ECFT

B= COP at 75% Load @ 23.9°C ECFT

C= COP at 50% Load @ 18.3°C ECFT

D= COP at 25% Load @ 18.3°C ECFT

NOTE:

*The Non-Standard Part-Load Value (NPLV) uses the IPLV formula with the following exceptions: the ECFT for part-load points varies linearly from the selected EFT to 65°F (18.3°C) from 100% to 50% loads, and fixed at 65°F (18.3°C) for 50% to 0% loads.
