Abstract: The apparatus for testing the stability of dispersed particles in flowing suspensions includes a sample receiving cup having a lower wall and an open upper end. A cup outlet is disposed in the lower wall, and the sample receiving cup is adapted for receiving a suspension sample through the open upper end. A pump is in fluid communication with the sample receiving cup through the cup outlet. The pump extracts the suspension sample through the cup outlet to produce a pressurized suspension stream. A recirculation pipe has a pipe inlet and a pipe outlet, the pipe inlet being in fluid communication with the pump for receiving the pressurized suspension stream, and the pipe outlet returns the pressurized suspension stream to the sample receiving cup, through the open upper end thereof. A power monitor is in communication with the pump for monitoring the power output of the pump.

Abstract: The air conditioning system with solar-powered subcooling system includes a main cooling system having an evaporator, a compressor, a condenser, and an expansion valve configured to operate in a conventional vapor compression refrigerant cycle. The subcooling system includes a compressor, a condenser, and an expansion valve, the compressor being powered by at least one rechargeable battery connected to a photovoltaic solar panel. The main system and the subcooling system are linked by a heat exchanger having a primary coil in the main system between the condenser and the expansion valve and a secondary coil in the subcooling system disposed between the expansion valve and the compressor. The main system and the subcooling system may use the same type of refrigerant, or different refrigerant types. The additional cooling provided to the refrigerant in the main system by subcooling increases the efficiency of the air conditioning system.
