Heat Pumps By: Kwok Lee 20198251 Objective: To give a basic understanding of heat pumps generally and how it functions.

What is Heat Pump? A system that transports heat around The most common type of heat pump is the geothermal heat pump. Other kinds include gas compression, thermoelectric and also phase change heat pumps Can be used year round Designs are improving and becoming more common to the public

How does it work? Generally, heat pumps compresses the heat existed in the air into a small concentrated area. The concentrated heat is then moved to a place where it is less heated, so that heat is given off until equilibrium is reached. The air then moved back to where it is originated and expand to again absorb heats in the atmosphere. This process is continuously repeated as long as the heat pump is operating.

Benefits Fuel is not acquired, and therefore safer and more environmental beneficial Conserves fossil fuels Uses less energy to produce more heat Consistent temperature over the whole atmosphere Preserves a higher humidity in the environment More efficient and economical than other kinds of heating Can be use perpetually and for a long term Works year round and compatible in almost all environments

Conclusion Heat pump is a very good system environmentally, economically, and by any means. Reference: http://home.howstuffworks.com/question49.htm http://en.wikipedia.org/wiki/Heat_pump
