Earth tube heat exchanger ppt
WebA heat exchanger is a component that allows the transfer of heat from one fluid (liquid or gas) to another fluid. Reasons for heat transfer include the following: 1. To heat a cooler fluid by means of a hotter fluid 2. To reduce the temperature of a hot fluid by means of a cooler fluid 3. To boil a liquid by means of a hotter fluid 4. http://www.healthyheating.com/Earth_tube_heat_exchangers/Earth-tube-heat-exchangers.htm
