Issues in the Design of Infrared Radiant Heating Systems.

摘要

In the 1970s and 1980s, the Army placed infrared heaters in many installation buildings as an energy-conserving measure. Radiant systems require less maintenance, have lower first costs, and are advertised as more energy conserving than conventional heating systems. Though radiant systems have generally met expectations, the relative benefits of radiant systems have never been formally studied. This study reviewed and tested industry claims for radiant heaters, and experimentally compared gas-fired low-intensity infrared radiant tube-type heaters to conventional heaters at Fort Riley, KS. Technical issues in infrared heating design and available design guidance were reviewed. This report includes a list of radiant heater manufacturers and presents the lessons learned from the experimental investigation. Experience and results from a field demonstration, informal survey, literature search, several site visits, and industry contacts indicate that low-intensity infrared radiant heating systems exhibit a potential for energy savings. However, proper implementation, control, and operation are essential to achieving these savings. There is also a need for a specific, nonproprietary guidance for designing radiant heating systems....
