Today, energy is indispensable to daily life all over the globe. Nevertheless, it is clear that energy cannot be consumed without limit given the finite nature of resources and environments. The consumption of abundant amounts of energy today unavoidably releases huge amounts of waste energy to the surrounding environment from houses, offices, shops, factories, subways and other facilities. Heat pumps can raise the temperature of waste heat to a usable temperature range through the use of a small quantity of driving energy. In this way heat pumps function like water pumps, which can lift river water to a higher elevation by using a small amount of driving energy. Thus if a piping network for gathering and transportating waste heat is available, heat pumps can efficiently supply useful heat to custmers by recovering energy from waste heat. If the waste heat of cities can be recovered, a kind of energy recycling system can be constructed using heat pump technology. This will result in the efficient use of energy and the conservation of ous precious natural environment. For individual use, a heat source network might be too expensive. But waterworks and sewer systems in cities can be used for this purpose with slight modifications. In many cities maintaining a sufficient water supply is becoming a real problem, leading to the promotion of water recycling and separate networks for the provision of drinking and non-drinking water. Sewers are one of the main repositories of waste heat, and sometimes waste heat is then diffused to rivers and lakes which are water supply sources. Ver documento. INTRODUCTION. USE OF ENERGY.
