Green / Yellow Vs Blue/ Purple/ Pink


Traditional Indicators color: GREEN & YELLOW
Tri-color Indicators : BLUE, PURPLE & PINK

Traditionally, moisture indicators have been green/yellow wafers that said the system was either “dry” (green) or “wet” (yellow). But, this simply does not go far enough. Here’s why. All moisture indicators share one common objective: to sense and report just how much water is in the system’s circulating refrigerant. A paper wafer in a sight glass changes color as the moisture content reaches potentially damaging levels. Those traditional green/yellow indicators do not, however, show percentage increases along the way; that is, they do not provide any true insight into the ongoing increases in moisture content. They simply announce, for example, that the system is “wet.” And by the time this “wet” indication is made, it may be too late to avoid damage to the compressor or other system components. There are other shortcomings as well. The green/yellow moisture indicators work only at higher levels of moisture, about 10% relative humidity (RH). Paper indicators are susceptible to damage from brazing during installation. And their color can actually wash out under wet conditions, leaving behind a useless piece of blank paper.

Alco Controls designed and developed the HermeticMoisture Indicator (HMI), the most sensitive indicator on the market. Instead of the old green/yellow papers, the HMI features a tri-color molded disk wafer dial with blue (dry), purple (caution) and pink (wet) indications. The addition of the purple caution color alone gives the HMI a critical advantage over previous indicators. It alerts technicians early on to rising moisture levels, allowing them to take corrective action before any damage occurs. And as the colors continue to change as moisture content rises, the HMI allows those same technicians to determine conditions more accurately, taking the guesswork out of their monitoring activities.

The Hermetic Moisture Indicator works by utilizing a unique salt that holds more water than a traditional gree/yellow indicator salt. This salt also changes through a wider color range than the green/yellow salt. Additionally, the indicator itself is thicker and together these attributes allow for a wide range of rich colors that enhance the ability to better understand the amount of water in the refrigerant. In addition, the HMI, along with all other moisture indicators, does not simply sense parts per million (ppm) of water in a system. Instead, it measures relative humidity. This is a significant distinction. Why? Because, for example, a reading of 50 ppm in R12 is extremely dangerous, while 50 ppm in R-410A is not. The difference is in the refrigerants. The new refrigerants, along with their POE oils, can physically hold more water; and since they operate at low ppms, this translates into extremely low relative humidity levels, in the 2% to 7% RH range.

There is a misconception across the HVACR industry that 10% RH moisture detection is sufficient. That’s an assumption that can lead to a dangerous – and expensive – false sense of security. At 3% RH in many HFCs, a green/yellow indicator will show a green color, pronouncing the system is still “dry.” In fact, it is actually at risk of acid formation from the breakdown of the POE oil. At 10% RH moisture detection, the system has already been contaminated with moisture and acids, and will need to be cleaned. That could mean anything from replacing the filter-drier and exchanging some or all of the oil in the system, to replacing a compressor or multiple compressors. Actually, the old green/yellow indicators show a “dry” reading as high as 7% RH. And a 7% RH reading in R-410A means there are nearly 300 ppm of water present. Emerson Climate Technologies’ studies have shown that acid begins forming at approximately 75 ppm, when water starts to turn POE oils back into acid. That means the newer refrigerants, with their high moisture content, see severe problems to the lubricant at 100 ppm. Any acid formation can be a problem, of course. So detecting moisture content as soon as possible is crucial to protecting the life of the system. Again, traditional green/yellow indicators fall short. By the time the indicator goes off, damage is already occurring to the lubricant. So it’s an indication that doesn’t actually indicate anything. Effectively monitoring an HVACR system for water content is already a critical step in assuring a long and useful life for the system. But it’s a step that cannot be taken if the view to the system – the moisture indicator – does not provide timely, accurate readings of the moisture level in the refrigerant. And as new refrigerants emerge, today’s traditional green/yellow solutions will fail to offer the insight and innovation needed to keep pace with the systems of tomorrow.

Lets look at the review from http://www.achrnews.com.

Oil Controls

When it comes to managing refrigeration systems, one of the main concerns is to keep the compressor lubricated while maintaining a high level of heat transfer and energy efficiency by removing as much oil as possible from the refrigerant. This requires sophisticated oil management devices.
Emerson's oil controls monitor oil levels throughout the refrigeration systems. The line includes:

* Suction accumulators
* Oil reservoirs
* Mechanical oil level regulators
* Oil level control systems
* High efficiency centrifugal oil controls
* Oil filters
* Acid test kits

What are the major differences between an R-22 and R-410A compressor?

There are three distinct design differences between and R-22 and R-410A compressor:

* Different Oil: Because mineral oil, normally used in R-22 compressors, is not miscible with HFC refrigerants such as R-410A, Copeland uses a synthetic Polyol Ester Oil (POE) in R-410A approved compressors.

* Reduced Compressor Displacement: A pound of R-410A has approximately the same heat carrying capacity relationship to R-22 as R-22 has to R-12, therefore, the compressor displacement has to be reduced approximately 40% for a given motor horsepower. Using a compressor designed for R-22 to pump R-410A would overload the motor and cause protector trips.

* Higher Shell Burst Pressure Requirement: At any given saturated temperature, R-410A has approximately 60% higher pressure than R-22, which require compressor shells to meet this higher pressure requirement.

How can the BTU rating of a compressor be determined?

Capacity ratings for Copeland® compressors are found on our published performance curves. These curves can be obtained through our wholesalers or from the Online Product Information section of our website. To use these curves, convert the measured suction and discharge pressure readings to their corresponding evaporating and condensing temperatures using a pressure/temperature chart for the refrigerant being used. Plotting those temperatures on the performance curve tables will reveal the BTU/H ratings, amperage, and watts.

Solenoid White Paper - Solenoid Valves and Their Importance in Refrigeration Systems

Solenoid valves play an important role within refrigeration and air conditioning systems, controlling the flow of refrigerants. Though their base function – turning the refrigerant flow on and off – is quite simple, this function is key to ensuring system performance. Understanding how solenoid valves work increases the likelihood that contractors will install, remove and reinstall valves correctly, ensuring optimum system performance and protection.
