“How can we remove heat from an area?”
HVAC systems are used to cool down rooms. However, how exactly do they do the cooling part? Well, if you were to move a cold fluid through a warm area, then heat would be transferred from the air to the working fluid. As a result, we can construct something called an evaporator coil, which moves the cooled refrigerant to be exposed to the surroundings.
HVAC Wind Turbines
“How can we use waste energy from an air compressor to power an HVAC system?”
Air compressors can generate a lot of waste steam when they are being used. However, if we use our engineering mindsets and think about the science of cogeneration, then we know that waste heat doesn’t have to be wasted. In fact, we if we install a wind turbine by a compressor, we can actually create energy from this process to power HVAC systems. This is known as an HVAC Wind Turbine and is a brilliant demonstration of engineering capabilities.
Biasing in Diodes
“What is it called when current can flow through a diode?”
Diodes are able to force current to flow in one direction. If current flows in a direction that the diode is not in polarity with, then the diode will block it. That being said, if the current flows in a way that the diode allows, then the diode is said to be forward biased. If the current is being blocked, then the diode is said to be in reverse bias.
Energy Storage in Buildings
“Is there a problem with renewable energy and buildings?”
Renewable energy has large implications for building energy use. However, one of the major problems is that it had difficulty being integrated into the grid systems, as all of the energy comes in as an active form. Therefore, we must consider how to integrate energy storage in buildings, whether it be through batteries or other devices.
Does Global Warming Slow Down Wind Turbines?
“How can climate change slow down our renewable energy portfolio?”
Wind Energy is one of the most fundamental renewable energy resources. However, research performed by the Energy and Resources Group at the University of California Berkeley have shown that wind in the Northern Hemisphere is actually in decline as a result of climate change. As a result, the more the climate warms, the less potential wind will have! So do your part and make sure that you live sustainably so we can have more potential for clean energy!
Machine Learning in Electric Load Forecasting
“How can we apply Machine Learning to estimate electric loads?”
Electric Load Forecasting if vital for making informed decisions about how to use energy throughout the day. And thanks to modern computational technology, we will be able to do such work by applying Machine Learning in Electric Load Forecasting. A computer algorithm can learn the past behavior of electric loads, and then make models to predict future behavior. Electric utility companies are investing large amounts of resources into developing these systems to increase their infrastructure.
Electric Load Forecasting
“Can we predict the amount of energy generation for a given day?”
Predict how intense the electric load will be for a given day is immensely useful. For example, we will need to know how much energy to generate or how much energy to take from a battery. This is known as Electric Load Forecasting and is one of the most important factors in the energy industry.
