| What
is unique about this section is the principles are covered in a manner that
makes it really easy to understand. Explaining
the 'changes of state' can be a dry topic. But relate that to an ice
cube melting in your hand; well now that makes it real easy. The physics
behind how an A/C system really works can be a dry topic; this section makes
it interesting and easy. Best of all, it's all detailed with professional
illustrations that help you remember.
While
the first part of this section covers all of the principles, the second part
starts by building a model automotive A/C system, one component at a time.
Starting at the evaporator, you quickly understand
how the A/C system transfers heat and makes the car cool. As the system
continues to build, all the other components are added one at a time until
the system is complete. You easily gain a complete understanding of what
each component does and how it effects the system.
As
the model A/C system continues to develop, all of the principles of physics
from the first part are applied. Therefore, because understanding the physics
was made easy, applying them to a model A/C system provides the reader with
a firm understanding of the overall operation
of the A/C system.
So
you're an old pro at auto A/C and truely think you're too advanced to
gain anything from this section? You already know the basics and have a real
good understanding of how an A/C system really works? Almost every professional
instructor in the feild has countless stories of service technicians who
want to take courses for advanced auto A/C service, but they
still can not explain the concepts of latent heat and
superheat and how they both play a very important role in the operation
of an A/C system. Understanding those simple concepts can quickly
eliminate hours of guessing and diagnosis time.
Just calculate the cost of the time you could waste and it's pretty
easy to see that it's equal to hundreds of times the
value of this manual. On the other hand, you could do what a lot of
other service techs do; they take the long way... they guess at parts
replacements, add refrigerant and recharge systems, never really pinpointing
the problem. That's sort of like just throwing parts and refrigerant at the
car until it's fixed. It could be really simple; understand the basics and
eliminate the guess work.
In
addition, this section also provides the basic gauge
readings for all the major A/C system designs on the road today, so
you learn the basics of what proper A/C system pressures should look like.
All
of the details are well illustrated in full color. This section on How the
A/C System Really Works also includes two full color WIZ
Charts. WIZ Charts are our unique Quick Reference guides that provide
great information from the section. They can be printed from the full version
of the manual so you always have them available to refer to. (The free
trial version does not include the WIZ Charts).
Also
covered in this section are:
- Detailed schematic illustrations of every auto A/C
system design on the road today; Each system illustration details
the changes in components and explanations of how they effect the operation
of the system.
- Component cut away illustrations; Get a better
understanding of what's really inside the receiver drier, accumulator or
expansion valve.
- WIZ Chart for Pressure / Temperature Relationships;
Includes references for the typical Evaporator and Condenser pressure ranges;
helps you understand if there is a problem on the system.
- WIZ Chart for Typical Gauge Readings; Covers all
the common automotive A/C System designs on the road today.
