Sun Powered Heat Pumps

Solar energy is fast becoming an alternative source of energy, and companies in the US are innovating solar-electric heat pump systems for residential and light-commercial space heating and cooling, and water heating. Solar-powered heat pumps can not only cool and heat residential spaces, and heat water, but can also provide emergency back-up power during blackouts and after earthquakes. Solar-boosted heat pumps would not only reduce electric power costs but can also help in reducing the frequency and duration of blackouts by reducing peak demand.

Sun-powered heat pumps are fitted with a solar collector panel and an evaporator on the roof, and a tank on the ground; the refrigerant is pumped to the evaporator and gets heated by air, solar radiation and even rain. The hot air then flows back into the condenser, which is a coil of tubing wrapped around the tank. Some solar-photovoltaic heat pumps also incorporate air conditioners that provide robust cooling in residential and light commercial applications. These devices use photovoltaic-made electricity and can be substituted directly as the input power for existing air conditioners, without making any major changes in the AC to adopt a solar-powered electric unit.

Sun-powered electric heat pumps are generally manufactured in 1- and 1.5-ton capacities, with eight 60-W and 80-W PV modules that operate in a vapor-compression cycle powered by a DC motor. A switch in the pump activates a reversing valve to pump refrigerant in the opposite direction, to turn the solar cooler into a solar heater in cold weather and back into solar cooler in the summer season. In order to maximize a heat pump’s efficiency, one can also connect a 4.5-COP-rated heat pump to passive solar storage cylinders or drum walls.

In today’s modern world, energy conservation is key, and solar-powered heat pumps are an excellent way to help solve global energy crisis.

Surface Grinders

Surface grinders are machine tools used to provide precision regarding the level, size or finish of the surfaces. The longitudinal feed is usually powered by hydraulics or cross feed, and any mixture of hand, electrical or hydraulic operation styles may be used depending on the ultimate usage of the machine.

The operation, once started, does not require supervision. But before starting the operation, the precision level has to be decided. This precision level differs for each operation and the operations may have to be done repeatedly to obtain the required precision. This process is called spark out. When the precision level is achieved without any inconsistency, the actual grinding process starts immediately.

The grinding wheels must be in good condition and the condition of the wheels is maintained using diamond dressers. These diamond dressers may be fitted to the wheel head or they may be placed on the tabletop. The cooling process is very important regarding these machines, so it starts right after the grinding process. Sometimes the cooling process starts as and when the grinding process is going on.

Surface grinders come up with lots of facilities. Precision surface grinders have absolutely vibration-free and noise-free operations. Some grinders have provisions for coolant applicants. In certain grinders, there are provisions for gathering the dust particles which are generated during the precision process. Different kinds of bonding systems are used in surface grinders. They may be metal bonds, resin bonds, vitrified bonds, poly bands or resin bonds. Each has its own distinctive features and advantages. A surface grinder can be operated in a manual or fully programmed mode. The PC-based control system is a recent innovation which allows someone experienced with non-CNC surface grinding to make the transition to CNC very easily. The graphical user interface with a touch screen panel is shown in the inset. The price range of surface grinders varies from $1500 to over $3500
