Refrigeration Equipment is a clear, practical guide to the installation, testing and servicing of industrial and domestic refrigeration equipment. Refrigeration technicians, who are poorly provided with good reference material, will welcome the author's hands-on approach. Other readers will include trainees on in-plant industry courses, building service engineers and maintenance staff in the frozen food industry, supermarkets, hotels and hospitals. It also provides a text from NVQs (C&G 6007) and other vocational courses).
