Heat Pumps Solar Powered
 |
A more and more common source of energy used nowadays, is the solar energy. Many companies in the United States are modernizing solar powered heat pump systems for inhabited and light-commercial space air cooling and heating, and also water heating. Solar electric heat pump systems do not only heat and cool inhabited spaces, and heat water, but they offer emergency back-up energy during blackouts and following earthquakes, also. Solar powered heat pumps do not only decrease electric power expenses but they also assist in sinking the regularity and length of blackouts by decreasing peak command.
Sun electric heat pumps are fixed with a solar collector panel and an evaporator situated on the roof top, and a tank on the land. The refrigerant is forced to the evaporator and it gets heated by solar radiation, air and even rain. Afterwards, the burning air flows back in the condenser that is a curl of tubing enfolded around the tank. A number of solar photovoltaic heat pump systems also include air conditioners which offer vigorous cooling in inhabited and light commercial appliances. These systems utilize photovoltaic created electricity and there is the possibility to be alternated straight as the input energy for existing conditioners, without making any important modifications in the AC to take up a solar powered electric unit.
Sun powered heat pumps systems are generally produced in 1- and 1.5-ton capacities, and eight 60-W and 80-W PV modules which function in a vapor compression sequence powered by a DC motor. A control in the pump sets in motion a reversing valve to force refrigerant in the contrary track, in order to turn the solar cooler in a solar heater into cold weather and back into solar cooler in the summer. In order to make the most of the pump’s effectiveness, there is also the possibility to connect a 4.5-COP-rated heat pump to inert solar storage cylinders of drum walls.
Nowadays, the energy conservation is the solution and the solar powered heat pumps are a very appropriate path to help solve the global energy crisis.
