On Demand Until May 29, 2020
Abstract:
Scenario 1: I set the compressor to maintain the pressure my chart indicates I need, to achieve the temperature I want in my evaporator. But the evaporator is operating at a warmer temperature! I must set the compressor setpoint to a lower pressure to get the temperature I need. Why doesn’t “temperature follow pressure” like I have been taught?
Scenario 2: I understand why I must set my compressor to a lower pressure than the P-T chart shows. But, my temperature is gradually rising even though I maintain the pressure setting that use to work?
Two different scenarios, two different causes for the same problem. The pressure-and-temperature relationship for a specific refrigerant is the basis of the operation of our refrigeration system. In this webinar, we will spend time looking at the factors that affect the application of this basic principle. Well explain how pressure drop and static head pressure will affect the operation of your system. Then, we will take a look at possible sources of water in your system and the effect that water will have on system operation and operating costs.
Also, we will take an up-to-the-minute look at the EPA Risk Management Program in this ongoing battle the EPA is waging to reduce the major impact of the revised RMP regulation. Some were scheduled in the revision to be delayed until March 15 of 2021. Some elements of the revision have now been in effect since early December of 2018. Learn where it stands today.
