Bearing vibration is an indication of parts wearing down over time. HVAC maintenance technicians use vibration tests to determine signs of wear and plan a proper maintenance course for the future. With this guide, you should be able to identify early signs of bearing vibration so you can call in an expert to run a full diagnostic test. Here's what that process looks like for you:
Commercial compressors are built for a wide range of functions and services. Oftentimes compressors are oversized for their intended application in hopes that they will last longer and take on fewer stresses with the extra headroom. However, this can also lead to challenges when it comes to maximizing the efficiency of the compressor within its operating range. This is where re-expansion gas comes into play.
Ice accumulation on evaporator coils is a common occurrence in refrigeration systems that operate below 40°F. To prevent excessive ice buildup on the evaporator coil and ensure optimal operation of refrigeration systems, a reliable and efficient means of defrost is often required. Two commonly used defrosting methods are the electric defrost and hot gas defrost.
Ensuring Food Safety and Quality with Accurate Temperature and Humidity Control
Under the new FDA Food Code, the businesses operating in the Food Industry are required to ensure appropriate control measures in order to eliminate or reduce the risk of foodborne illness at the consumer level. To ensure food safety, the perishable foods susceptible to spoilage by disease-causing microorganisms, such as bacteria, fungi, and viruses, must be kept in adequate containers, at safe temperatures during processing and transportation.
The Air Conditioning Contractors of America (ACCA) posted that they published a technical update on “Air Conditioning and Refrigeration Systems Using Flammable A3 Refrigerants” on July 26, 2018. The technical update concentrates on the challenges that technicians have to deal with while working on the products that run on flammable A3 refrigerants.
Eliminating moisture, odors, airborne particles, and bacteria from indoor environments to increase proper airflow through HVAC systems play a critical role in public, commercial and industrial buildings. Furthermore, studies have been indicated a strong correlation between indoor air quality and employee performance and productivity.
