THERMAL ENGINEERING

VNU-HCM PUBLISHING HOUSE – 2014

PREFACE
Nowadays, with the developing of science and technology, the
thermal engineering plays an essential role in the industry and life.
Thermal techniques are widely applied in the fields of cooling, heating,
freezing, renewable energy etc. In addition, most d knowledge in
this area is in English, so if students hunger for knowledge, they must
enhance their English in general and technical English in particular.
Foreseeing this matter, as well as the urgent demand to provide a
standard textbook for students of the Department of Heat and
Refrigeration Technology - HCMC University of Technical Education,
the authors have synthesized the most basic knowledge of reading and
writing English to write a textbook with a title being English for Thermal
Engineering. This textbook is utilized for students who are in the
Department of Heat and Refrigeration Technology and for the
concerning-technical staffs.
Although the authors have tried our best, errors are unavoidable.
We welcome and appreciate any comment from the readers. Letters
should be sent to the address: Faculty of Automotive Engineering HCMC University of Technical Education: 01, Vo Van Ngan St., Thu
Duc District, Ho Chi Minh City.
