Presented by Kevin Miskewicz and Joe Cefaly

Learning Objectives:

  1. Identify current industry trends driving the adoption of specialized ventilation systems, as well as relevant standards and codes, including ASHRAE 62.1 and the International Mechanical Code (IMC).
  2. Describe the similarities and differences between ERVs and DOAS in terms of function, impact on cooling and heating loads, and how each is applied with VRF systems.
  3. Discuss DOAS design options and requirements with consideration for decoupled DOAS, duct distribution networks, energy-efficiency measures such as demand-control ventilation, and refrigeration circuits engineered to provide cooling plus reheat.
  4. Explain how applications dictate appropriate ventilation solutions with consideration for building codes, climate, humidity, and how a space is used.
