I realized that if you want to have an in-depth learning of Heat Transfer, one should study an HCAC system. I suppose it doesn't matter if it is an industrial scale system or an ACU in your home. Both in the end work within the principles of Heat
We installed in January a 5.85kW hybrid system with (2) 100Ah/ 48V batteries. Now that I think about it, the number of modules charging the batteries is a bit inadequate but it can't be helped due to lack of roof space. And to think even further, I
Starting Nov we were contracted with inspecting 120 stores. The first 20 stores were inspected with Choy and myself and the other 40 by me and Bop. Through our experience for each store we've continued to refine our techniques and data gathering. Interesting Finds This is one instance
If you go up a cooling tower, its best to not go alone. There are 6 cooling towers. Cooling Tower #1 is redudancy and Cooling Tower 6 had a blade that failed due to unbalance. So 4 cooling towers are in operations all the time. We had a discussion to
Just got this in the mail recently. In order to understand criticality rankings, its good to get a good grasp on Reliability as a whole. In the next couple of years I need to have a strong base on all of these fields: 1. Thermography 2. Vibration 3. Ultrasound (All
Today we had a training session on thermography. The most important part of the session was the hands-on. Once we got started, the first panel we opened had a thermal anomaly. Before the images above we actually measured 164degC. This is why Proactive Maintenance principles need to be applied before
We were taken the pump room for the first time, 2nd floor. Engr. Jim told me about these 4 pumps. It seems like there are pressure issues due to failure of some components. The tenants upstairs experience a drop in water pressure as a result. He told me the right
The Rockwell manager Jim mentioned in a meeting that two of their chiller systems (2 & 3) have experienced leaks. This is after I presented to their management our Condition based monitoring activities in the facility. Chillers usually don't need to refill R134 for a decade. But 2
July 15, 2025 Will have a zoom call with La Sagesse, Rehab Center for their PV solar system. Propose a 40kW system. This is has been in the works since 2023. Funding is an issue. The Sisters had to fund raise. The Church has decided to fund the rest. It&
On June 5, 2025 conducted a ultrasound and vibration inspection on all the available motors and pumps. Looking at the data was very interesting, full of sound and vibration. Both provide a TWF and FFT, but the point that these two data sets bifurcate is the fault frequency signature. Ultrasound
