I started to use Microsoft Copilot AI tool for research last year before the election, but I stopped using it after it refused to respond to questions regarding Donald Trump and the elections. All I wanted was a quick verification of the facts. But the Copilot product would not comply. So, I switched to the Google Gemini AI tool. It has been more cooperative, though I can’t verify if Gemini would have failed to answer election questions in the same way.
AI is in our future. It does too many things well enough, and a fully developed AI tool could change our economic system and change the way we live. It is not there yet, because it is immature in many ways. In my experience, AI can give you bad answers if you are not careful.
I asked, “Are heat pumps more efficient than conventional air conditioners?”
In its introduction, Gemini said, “When it comes to cooling a house, heat pumps and conventional air conditioners are essentially the same in terms of their operation and efficiency. Both systems use a refrigerant cycle to absorb heat from inside your home and release it outdoors.”
At this point I had a correct but incomplete information for my short essay Heat Pumps. Later, I felt that there was more to heat pumps, so I asked more questions.
I asked Gemini, “When cooling, why do heat pumps maintain the same temperature?”
Gemini replied, “Heat pumps are designed to operate most efficiently when they are maintaining a steady temperature, rather than constantly cycling on and off. This ‘set it and forget it’ approach is often the most effective way to use a heat pump for both heating and cooling.”
I asked, “Do heat pumps heat or cool their heat-exchange liquid to the same temperature as the setting?”
Gemini responded, “That’s a great question that gets to the heart of how heat pumps work. The answer is no, a heat pump does not heat or cool its refrigerant to the exact same temperature as the thermostat setting. The refrigerant’s temperature is significantly different, and this difference is what allows the heat transfer to occur.”
Gemini continued, “This is a key reason why it’s important to set a steady temperature on a heat pump. By maintaining a constant set point, the system can operate at a stable, efficient rate, continuously moving heat to maintain the desired temperature differential rather than struggling to make a large, rapid change.”
I then asked, “How does the heat pump continue to run while maintaining the same temperature?”
Gemini responded, “Unlike older, single-speed heating and cooling systems that would simply blast on at full power until the set temperature was reached and then turn completely off, modern heat pumps are much more sophisticated. The most advanced systems use what’s called a variable-speed or inverter-driven compressor.”
“So, while the unit is technically ‘running,’ it’s not always running at full blast. It’s working smart, not hard, to make tiny, continuous adjustments that keep your home at the perfect temperature without a major energy expenditure.”
After asking for more details, I had a better understanding. Heat pumps use the same heat exchange principle as conventional air conditioners, but the heat pump control mechanism is much more sophisticated and takes advantage of efficiencies in running continuously.
AI is very good, but must be questioned further when the answers seem incomplete.
