HEAT PUMP WATER HEATERS ABSTRACT This paper presents an overview of the solar boosted heat pump water heater technology. The tests made on direct expansion solar assisted heat pumps have shown that good COP can be attained while using working fluids that do not cause any harm to the environ ment. Modifications to the condenser in the heat pump can be made in order to improve and distribute evenly the heat transferred to the water. NOMENCLATURE HPWH – Heat Pump Water Heater SBHPWH – Solar

The 21st century witnesses the flourishing of space science and technology. More and more countries have come to realize the need for international cooperation to explore outer space‚ even though considering the complexity‚ high cost and tremendous risk involved in outer space activities. The human world and outer space are now increasingly inseparable.

The only way to find out would to be to continue the complicated research of space that has been going on since the space race. However space exploration is surrounded with controversy which may possibly affect the growth of the knowledge of space. The prior benefits and consequences of space exploration now affect the present and future of space exploration.
