VARIABLE REFRIGERANT FLOW: A VERSATILE HVAC SOLUTION FOR K-12 EDUCATIONAL FACILITIES

摘要

Architects who are primarily responsible for designing K-12 educational buildings have likely heard of Variable Refrigerant Flow (VRF) HVAC systems. However, it is unlikely that many have experience designing with VRF systems or a comprehensive understanding of VRF systems and their benefits. K-12 educational facilities face a long list of HVAC challenges, including occupant comfort and the need for a high level of control. Other specific challenges to K-12 educational facilities include: stringent indoor air quality requirements (especially pertaining to ventilation), the need for low noise levels, a range of comfort demands across a variety of spaces and occupants, and a preference for simple maintenance. A school's challenges also change depending on its location in the country; for example, a school in Florida will likely have humidity concerns while a school in Vermont will often face cold-climate heating challenges.
