Back to Basics: Controlling Hot Gas in Direct Expansion Systems
Do you want to be known as the engineer that mixed up hot gas reheat with hot gas bypass? If not, you should attend this seminar.
Refrigerant control valves are used for a multitude of purposes in both refrigeration and comfort cooling HVAC systems. Many different types are available, each with their own unique function and application, but these valves are not interchangeable and specifying or selecting the wrong one may result in project delays, avoidable costs, inadequate performance, and premature equipment failure. In this seminar, we will review commonly used accessories such as hot gas bypass, reheat, low ambient control, heat reclaim, and pressure regulating valves and the purpose that each one serves in the refrigeration system, and where and when to apply them.
