The present invention relates to a script management technology. Disclosed are approaches for managing scripts carried out in a script management server, which is connected to a user terminal and which manages script codes. Approaches comprise preparing a plurality of databases including a meta database and a plurality of script databases without necessarily separating physically the two types of databases; designating an active script database by providing the plurality of the original script lists to the user terminal; and storing identifiers of the user terminal and the designated active script database in the meta database, where the plurality of script databases are classified according to script version and each of them manages the original script code and user-specific script code, and the meta database manages a plurality of the original script lists related to the plurality of script databases and a list of user-specific scripts.

A regenerative evaporative cooler, designed to improve the cooling efficiency of its regenerative evaporative cooling unit, is disclosed. In the cooler of this invention, the cooling unit consists of a dry channel and a wet channel arranged to closely come into contact with each other. The dry channel allows primary air to pass through, while the wet channel extracts a part of the primary air from the outlet end of the dry channel so as to form extracted air flowing in the wet channel in a direction opposite to the flowing direction of the primary air. A plurality of cooling fins are arranged in the dry and wet channels to allow the extracted air to come into direct contact with water so as to improve the water vaporization efficiency and the water vaporization area in the wet channel. A first blower fan sucks the primary air into the dry channel, while a second blower fan sucks a part of the primary air of the dry channel into the wet channel so as to form the extracted air. A water supply unit feeds water to the wet channel. In the cooler of this invention, the extracted air flowing in the wet channel absorbs heat from the dry channel by means of the wet channel fin, thus cooling the primary air flowing in the dry channel.

A method and apparatus for generating uniformly sized spherical ice particles. The apparatus comprises a water feed pump, a vacuum chamber connected to the water feed pump and having a water spray nozzle, boosters discharging the vapor from the vacuum chamber to maintain the inside of the vacuum chamber below a desired pressure and compressing it, a condenser for condensing the vapor being compressed by the boosters, and a vacuum pump for removing noncondensable gases from the condenser. The method comprises the steps of decreasing the pressure of the vacuum chamber below the first pressure, feeding water from the water source to the spray nozzle of the vacuum chamber, making spherical ices by spraying the water being fed from the nozzle into the inside of the vacuum chamber, in which the size of the droplets being sprayed is below a desired size, during said ice making step, maintaining the pressure of the vacuum chamber below the second pressure by discharging the vapor from the vacuum chamber and compressing the vapor to increase its saturation temperature above room temperature, condensing the compressed vapor within the condenser using water at room temperature as coolant, and draining the water being condensed during the condensing step and removing noncondensable gases.
