Glossary of HVAC terms. HVAC (heating, ventilation, and air conditioning) is a major subdiscipline of mechanical engineering. The goal of HVAC design is to balance indoor environmental comfort with other factors such as installation cost, ease of maintenance, and energy efficiency.
RTV Silicone. Room Temperature Vulcanizing (RTV) silicone is a rubber polymer used to create molds, prototypes, and sealant. It is extremely flexible and quite tear resistant. It is made up of two separate components: a base and a curative.RTV silicone can be poured, sprayed, brushed, or pumped onto a surface.TV silicone is made through a process known as vulcanization. This process involves mixing rubber polymers with additives such as sulfur in order to make the silicone harder or more flexible. Humidity in the air cures RTV-1, a single compound RTV silicone type, which is available in both fluid and paste forms.
