Consider these factors when sizing up a potential upgrade. In addition, pick up a few easy tips for maintenance in the meantime. You can’t necessarily buy time, but you can get in front of a worst-case breakdown scenario.
In which the author explores the specific strengths and attributes of various boiler types, along with pumping options and other system factors. The goal: To help you intelligently align your project’s equipment choices with its particular load, meeting expectations while avoiding Delta T headaches.
The particular charms of panels, chilled beams, and related options seem to be at-tracting more attention from designers and owners these days. Design, installation, and even architectural considerations can earn a hard look at radiant for a surpris-ing number of applications.
It might seem like an odd objective, but the potential efficiency gains are real. And from heat recovery chillers to modified humidification targets so are the opportunities to replace steam production with hot water generation and to manage remaining steam needs more intelligently.
The production of thermal power is critically important in carrying out the mission of health care facilities where it is used for space heating, humidification, domestic water heating, and for processes in dietary, laundry, and sterilization departments. The age of the hospital, the programs offered, and the regional climate will all affect the demand for thermal power.
So many areas where a little forethought and awareness can avoid larger problems — sizing, velocity, piping and connections, double trapping, condensate return, proper pressure, blowdown tanks, and more. Read on for some good habits and why they’re worth having.
When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly.
Leaning on experience and data from various K-12 cities and projects, the authors pursue some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
