摘要： A multiroom air conditioner has a plurality of indoor heat exchangers connected to a single outdoor heat exchanger. A reversible expansion valve is installed on a liquid-side branch pipe for each of the indoor heat exchangers, and a solenoid valve is installed on a gas-side branch pipe for each indoor heat exchanger. Temperature sensors are provided on the liquid-side branch pipes, on the gas-side branch pipes, and on the outlet side during cooling of the outdoor heat exchanger. A pressure sensor or a temperature sensor detects the saturation temperature on the high-pressure side of the compressor. Based on the saturation temperature on the high-pressure side of the compressor, the temperature on the outlet side during cooling of the outdoor heat exchanger, and the temperatures in the liquidside branch pipes, a controller controls the expansion valves so as to obtain a target degree of subcooling during cooling and heating. The controller can also control the expansion valves so that the temperatures in each of the branch pipes are approximately equal to one another.

摘要： The cooling performance of an air conditioning apparatus is controlled by a selective combination of three methods of regulation, in accordance with the required degree of cooling. A first stage of regulation controls the volume of air delivered by a fan 6, a second stage controls the amount of refrigerant flowing through a pressure reduction means 7, and a third stage controls the amount of refrigerant circulating in a compressor feedback circuit 9. Any one of or combination of these three controls may be employed in accordance with the prevailing temperature condition and the required cooling performance.

摘要： A product obtained by granulating an enzyme powder must avoid emitting dust, possess high strength, exhibit the property of quickly dissolving in water where such ready solution is necessary for the intended application, defy absorption of moisture or deformation for a long time, and preserve without a sacrifice of activity. The method of this invention produces granules of raw enzyme powder possessed of the qualities mentioned above by admixing the enzyme powder with polyethylene glycol or polyoxyethylene-polyoxypropylene block polymer of specific quality as a binder and granulating by agitating the resulting combination at a temperature not lower than the melting point of the binder. This method is suitable for production of enzyme-containing granules for use in detergents, medicines, etc.

This particle transfer can occur while the reaction mixture is agitated. The tantalum particles can be automatically withdrawn when the reaction mixture has a depth level greater than the fluid level of the tantalum fine particle recovery vessel, and outflow automatically stops when the fluid levels of the reactor and particle recovery vessel equilibrate. Tantalum or other valve metal powders made by the processes, and capacitors made with valve metal powders are also provided.
