| Summary: | The population growth of the world has led to a greatly increased demand for energy. Due to this growing global energy demand and concern for environmental degradation, the potential of running thermal system using solar energy is receiving considerable attention in recent years. Solar energy is clean and most inexhaustible of all energy resources. The heat pump commonly used for space cooling, a low temperature application, makes it an excellent match for the use of solar energy. A solar assisted heat pump system has been fabricated and installed for space cooling, water heating, drying and desalination. Besides solar energy, the system makes use of waste heat available from heat pump, which is normally released to the atmosphere leading to global warming. An unglazed evaporator collector absorbs solar energy and ambient energy. On condenser side of the heat pump, desalination chamber, water heater and cloth dryer are connected to make use of waste heat available from the heat pump system. This system is particularly suitable for hotels and hospitals where cooling, water heating and drying are always needed and enormous amount of waste heat is available. |
