Titled “Waves of Love,” he was searching for a more feminine energy this season. To say he toned down the color is a bit of a stretch, but this season he used softer pastels on T-shirts and even debuted his version of a khaki pant, though still embellished with subtle ruffle pleats at the pocket.

He used stripes as waves as touch points, particularly well on a pink and green pajama-style shorts suit.

Technicians won’t lose their necessity with these changes, but it will be easier for them to respond to those measurements directly without connecting gauges. The future of troubleshooting will eventually lie in electronic controls that take measurements constantly.

Technicians need to learn how to take their time and do the job right when they work on CO2 equipment so that they can be safe and save energy. These issues require skilled, attentive technicians.Īs the industry moves to natural refrigerants like CO2 and hydrocarbons, we need to stop the race to the bottom. Since CO2 can exist as a liquid, vapor, or solid under operating conditions, you could end up with dry ice in the system. However, CO2 has some challenges, including its low critical point and higher pressures.ĬO2 comes with some safety concerns, and its systems have a complicated infrastructure. CO2 is one of the most eco-friendly refrigerants on the market, with a GWP of 1, and it’s very good at moving heat. Trevor Matthews, the founder of Refrigeration Mentor, returns to the podcast to talk about why CO2 matters in commercial refrigeration and even HVAC applications.ĬO2 (R-744) has entered the residential HVAC sphere in some places around the world, though it hasn’t come to the North American markets yet.

Nylon, brass, and stainless steel brushes.Basic chiller and cooling tower anatomy.Goodway has a vacuum that collects the debris in the basin without having to drain the entire thing. People also need to tighten the brushes to their cleaning machines with channel locks when techs don't tighten those brushes properly, the brushes can fall off, which is not good for the chiller.Ĭooling towers act as filters, so they collect a lot of debris in the basin. “Chiller bibs” also exist to catch the water and transport it to the drain with less of a mess.Ĭleaning machines often have foot-pedals, and people commonly put toolboxes or other heavy objects on foot-pedals, which is a bad practice.

So, floor cleanliness is important when wrapping up a job. When cleaning the chiller and cooling tower, the water flows onto the floor and to a drain. Cleaning the tubes is usually easier than taking the heads off the chiller. To access the tubes, you have to take the heads off the chiller. In those areas, cleaning should happen at least once or twice per year. So, tube cleanliness is important, especially in high-traffic areas. Water hardness can also interfere with heat transfer harder water will lead to more mineral deposits. When scale or debris buildup occurs, heat exchange becomes much less efficient. Goodway makes industrial maintenance equipment for the HVAC industry, especially tube-cleaning equipment.Ī chiller has water running through the tubes, and debris from the cooling tower can build up in the tubes. In today's podcast episode, Mark Roth from Goodway talks about chiller and cooling tower cleaning best practices and techniques.
