Hitachi Plant Technologies is to target the sunnier parts of the world with a new environmentally friendly air conditioning system based on solar thermal power.
The Solar Power Airconditioner is based on a parabolic trough reflector that can track the sun automatically. At the focal point of the reflector is a fluid-filled heat collector tube, which flows into an otherwise typical air conditioning system to provide the energy needed for refrigeration.
This solar power airconditioner system is designed to drive a refrigerator directly with thermal energy generated from the solar energy collector to obtain chilled water for air conditioning.
As the key to this system, Hitachi Plant Technologies developed its own original designed high-efficiency parabola trough-type solar energy collector. The collector is improved through design features such as its simple and easily-handled structure, and the use of computer simulations to develop a design for control of displacement of the focal point in the presence of wind and other factors.
Hitachi Plant Technologies supplies a total system incorporating the solar energy collector, as well as presenting proposals for combinations of energy-efficient technologies for air conditioning systems, and water treatment technologies.
Stating that it is now expanding market activity, Hitachi says that it expects the system to be deployed in parts of the Mediterranean, North America, Western Asia and Australia – the so-called “sun belt”.
Hitachi says that the system, which is based around the company’s own proprietary parabolic trough design of solar collector, will drastically reduce electrical power requirements when compared with standard air conditioners during periods of strong sunshine – although it is yet to quantify the impact.
But the company certainly has a huge amount of experience when it comes to industrial systems, and it expects the solar thermal approach to have a much wider range of application beyond air conditioning, in a variety of heat sources.
