1. INTRODUCTION AND SPECIFICATIONS
INTRODUCTION 1.1
The AMRON INTERNATIONAL Inc. Model 9000-ECS, Environmental Control System is
designed to provide chilled or heated fluid for temperature control of Deck Decompression
Chambers. The Model 9000-ECS is used in conjunction with an internal conditioning (heat
exchanger) located inside the DDC.
The Model 9000-ECS is a self-contained unit, using a sealed R-404A refrigeration unit, fluid
reservoir, circulation pump and heater. The system can supply cooled or heated fluid,
operator selected, to provide heat or cooling for the DDC as required. A small circulation
pump circulates fluid (50% propylene glycol, 50% water) through an internal reservoir, where
the fluid is heated or cooled, and on to the chamber where heat is extracted or added as
desired, via the internal conditioning unit.
The Model 9000-ECS is suitable for use on most all double lock decompression chambers.
This includes units ranging in size from 54 inch through 72 inch diameters. There are certain
conditions where the heat load may exceed the capacity of the unit. These conditions may
occur when the chamber is being pressed to depth, when the chamber is located in direct
sunlight, when the chamber is being operated in a very high or very low ambient
temperature, with a high number of personnel within the chamber, or a combination of these
factors.
Most of these conditions can be overcome by operating procedures. During initial press
down of the chamber the amount of heat added to the chamber (compression of the air) will
cause a rise in the temperature of the chamber. To compensate for this heat load, the
chamber can be pre-cooled. Sun shades or other temporary structures can be erected for
operating conditions outdoors or under extreme conditions.
