Question- how can heating and cooling be made more efficient
Heating and cooling has undergone many changes and continues to experience changes. Since its invention in 1902(1), the field of heating and cooling has improved drastically. Heating and cooling units, we see today have successfully achieved everything they needed to do power in terms of comfortability (2). However, there remains much room to improve the efficiency of heating and cooling. Improving the efficiency of will both help the environment and take dollars off your electricity bill. This essay explores the future of heating and cooling and the current state of heating and cooling, plus some ways to make your home more efficient (3).
Heating and cooling are responsible for fifty percent of the average person’s electricity bill (an old heating unit can cost up to five hundred dollars a month), but with a few changes that fifty percent can be turned into a thirty percent. The easiest of these changes is not much of a change at all, checking your household ducts for leaks. Leaks lead too unnecessary heat use and heat equals energy. Another simple thing that you should do is check if your temperature control system is in good condition. If the system is broken and in need of replacement, temperature control systems with an EER (energy efficient rating) are a recommended because if you are replacing your system replace it with an efficient system. A thing to consider when buying a new system is the right size; a house doesn’t need a mansion sized heating system (3).
Decreasing your heating and cooling energy use by twenty percent is all that is possible with current technology, even with making your house super insulated with no excess use of heat. The temperature control systems are good but they can be better. New temperature control systems are in development both for heating and cooling. For AC (air conditioning) people are developing units that utilize motion sensors, dual energy source (solar and gas) powered, and AC units that run on a re freezable tank. For heating the new systems focus on harnessing heating from existing sources and redistributing that heat to areas that need to be heated. One of these systems is already in use is geothermal heating; it uses the natural heat from the ground to heat apartment buildings. The reason it is only used in apartment buildings is it generates too much heat for a normal house (4). Scientist at Stanford are trying to develop a system that works similarly to the heating systems previously mentioned in the sense of harnessing existing temperature a redistributing it. They have successfully harnessed the coolness of space to cool an area. However, implementation of this concept is a way of because it is very expensive and bulky (5).
A big thing about efficiency is the power source used most of the current heating and cooling systems use gas. However, solar power is much better than gas in very way. Solar power is better for the environment and cost less than buying electricity from the city. No doubt future temperature control units will run on solar energy (6).
