Abstract: This ice making machine includes an ice making unit that includes an ice making surface and a cryogen flow channel through which a cryogen for cooling the ice making surface flows; a pump that pressurizes and discharges the cryogen cooled by a heat exchanger; and a control unit that controls a discharge amount of the pump. The cryogen is carbon dioxide, and the control unit controls the pump such that the cryogen is in a gas-liquid mixed state at an outlet of the cryogen flow channel.

Abstract: Provided is a means for more efficiently generating ice which has a high cooling capacity. A flake ice production device generates ice by cooling the wall surface of an inner cylinder and freezing brine that has adhered to the wall surface of the cooled inner cylinder. A spraying unit supplies brine to the wall surface of the inner cylinder by causing the brine to adhere thereto. A stripping unit collects the ice generated on the wall surface of the inner cylinder. In addition, the flake ice production device is designed such that formula (1) is satisfied when Y represents an ice making speed indicating the amount of ice generated on the wall surface of the inner cylinder per unit time, and x1 represents the thermal conductance rate of the wall surface of the inner cylinder. Formula (1): Y=f(x1).

Abstract: Provided are: ice which has excellent cooling capacity; a production method therefor; a method for producing a cooled article; and a refrigerant. Also provided are: ice in a non-separating state; and a production method therefor. The present invention pertains to ice which satisfies conditions (a) and (b) and is from a liquid that includes an aqueous solution comprising a solute. (a) The temperature of the ice after melting completely is less than 0° C. (b) The rate of change of the solute concentration in the aqueous solution generated from the ice in the melting process is 30% or lower. The refrigerant of the present invention includes said ice. The refrigerant also includes water which comprises the same solute as the solute included in the ice, wherein the ratio of the concentration of the solute in the ice and the concentration of the solute in the water is preferably 75:25 to 20:80.

Abstract: An indoor and outdoor cooling system that is provided with a one or more nozzles that are adapted to spray a fine water mist into the air. The cooling system also includes a fan and a dehumidifier. The dehumidifier is adapted to introduce dehumidified air into the area being cooled. The mixing of the dry dehumidified air with the water mist causes the water mist to evaporate which causes the removal of the vaporization heat from the surrounding air to lower the air temperature.

Abstract: A snow making apparatus that allows for the production of snow when the outdoor air temperature is from about ?3° Celsius or colder to about +5° Celsius. The snow making apparatus includes a snow machine that includes one or more water nozzles that spray a water mist into the air. The snow making apparatus also includes a snow accelerator that includes an air compressor, a dehumidifier to remove moisture from the compressed air and a cooling system to cool the compressed dehumidified air. The cooled air is passed through an expansion valve and the modified compressed air is directed through a nozzle positioned to lie near the water nozzles. The modified compressed air has a absolute humidity of about 0.02 g/m3 or less and a temperature of about ?50° Celsius or less. The water mist and modified compressed air are combined, causing the water mist to turn into snow.

Abstract: The present invention provides an ozone emitter, which can continue to emit ozone gas for a long time, which can continue to exert effective detergent and bactericidal action due to ozone gas for a long time, and which is easily portable, a method and equipment for producing the ozone emitter, and a method for utilizing the same. The ozone emitter is provided in such a manner that ozone gas is filled into a container which is obtained by forming an ozone gas impermeable film material in a container shape, wherein the film material is provided with a number of fine permeable pores through which molecules of ozone gas can permeate.
