1.4规范和规定
任何暖通空调设计师都不应首先了解并熟悉管理和规范建筑施工、产品设计和制造、工程师资格的各种规范和条例，然后才承担设计任务

并且将拒绝使用；而设计师故意违反规范只会带来极大的个人风险。
每个暖通空调设计任务的推荐做法是：
对当地执行的法规和条例进行初步审查，
彻底熟悉适用段落，并
虔诚地遵循规定的做法，即使这种做法似乎会扼杀创造力。
有时，代码约束似乎违反或干扰

the second is a publicly documented, formal procedure. The HVAC
system designer will benefit greatly if she or he can commit to an
analytical thought process which defines the problem, proposes solutions, identifies the optimum approach, and finally presents the solution in a credible and compelling way.
1.4 Codes and Regulations
No HVAC designer should undertake a design task without first having an awareness of and hopefully a working familiarity with the various codes and ordinances which govern and regulate building construction, product design and fabrication, qualification of engineers in
practice, etc. Codes generally are given the force of law on the basis
of protecting the public safety and welfare. Penalties may be applied
to those who violate established codes, and the offending installation
may be condemned and regarded as unsuitable for use by enforcement
authorities. As young design practitioners, we were advised to ‘‘curl
up with a good code book’’ until we became thoroughly familiar with
its precepts.
Codes are particularly definitive regarding a building’s structural
integrity, electrical safety, plumbing sanitation, fuel-fired equipment
and systems, fire prevention detection and protection, life safety and
handicapped accessibility in buildings, energy conservation, indoor air
quality, etc. Each of these areas has an impact on the design of HVAC
systems.
Particular codes are sufficiently diverse in their adoption and implementation that it is unwise for this book to list any specifics. The
HVAC system designer should simply know that life is not without
constraint; that systems will conform to codes, or else a permit to build
and use will be denied; and that willful violation of codes by the designer is done only at great personal risk.
The recommended practice for every HVAC design assignment is to
make an initial review of the locally enforced codes and regulations,
to become thoroughly familiar with the applicable paragraphs, and to
religiously follow the prescribed practices, even though such an approach seems to stifle creativity.
Occasionally code constraints seem to violate or interfere with the
objective of a construction. At these times, it is often possible to request a variance from the authority. There is no guarantee of acceptance, but nothing ventured, nothing gained. Good preparation generates hope and understanding, and differentiates you from the
unending stream of charlatans who seek to sidestep codes and regulations for personal financial gain.
