Upon viewing this lesson a student should be able to understand what evaporators do, what affects their performance and what one is supposed to know to troubleshoot this integral component of the HVAC system.
Free Online Webinar is part of our HVAC Prep Course series: Evaporators, we discuss evaporators more in-depth. We talk about what they do and how they absorb the heat. Along with that, we discuss the proper temperature and pressure. In our Online HVAC Prep Course, we pay attention to that because pressure affects temperature, so we go over what happens if pressure is too low or too high. We take a look at pressure gauges and PT charts built into gauges. We discuss de-humidification, proper Delta T of the air and Evaporator super-heat.
Our Free Online Webinar looks at the different types of evaporators: multi-circuit evaporators, stamp plate evaporators, and fin tube evaporators. We follow this by the introduction of the rule of thumb on superheat, and then we learn how to calculate superheat.
In this Free Live Webinar, we continue the discussion with the presentation of how the evaporator absorbs the two types of heat, and how this affects the comfort in the treated space. We look at problems that may arise with evaporators and what may cause these problems. Another item that we discuss is defrost and ways to defrost the evaporator.
