Subject:      Dramatically Improving AC capacity
Content-Type: text/plain; charset="iso-8859-1"

Hi Volks:

The one deficiency remaining unresolved with our Vanagons - is the
inadequate capacity of the AC system, and I'd like to start a thread dealing
with remedying that.

Problem:

The AC capacity of our Vanagons is inadequate to reject the amount of heat
to necessary to maintain passenger comfort on very hot and humid days.

Background:

Many of us have worked hard to improve our AC system's efficiency, both by
improving the thermodynamic efficiency and by improving the airflow, and
that's great. However, on very hot and humid days - it is barely adequate
but usually inadequate for complete respite from discomfort.

Discussion:

There are several approaches to improving the AC system available:

1.    increasing the capacity of the existing system;

2.    installing a higher capacity system to replace the existing one;

3.    Installing a secondary AC system to provide additional heat-rejection
capacity;

4.    Alternative approaches not listed.

Each of these approaches is a compromise between cost (including time), ease
of implementation,  reliability and likelihood to meet performance
requirements.

Action:

I request that specific ideas be brought forward from the list, and that
these ideas be framed by the points 1 - 4 above. By framing the ideas as
requested, we can keep the discussion organized.
