摘要： PROBLEM TO BE SOLVED: To control the temperature and humidity of humidified air to predetermined values, and to eliminate the occurrence of variations in the temperature and humidity of the humidified air, by constructing a device to mix the humidified air with the air that has passed through a bypass passage in a mixing chamber. SOLUTION: Indoor air 54 is pressurized by a main blower 41 to be supplied into an air chamber 2 from an air supply window 13. This air is humidified, and flows into a mixing chamber 5 as cooling air 51. The part of the air in the air chamber 2 is supplied into a bypass passage 6 by a sub blower 20, and flows out to the inside of the mixing chamber 5. This bypass flow 52 flows out to the inside of the mixing chamber 5 in a roughly perpendicular direction to the cooling air 51, so that the mist that is being generated at the time of bubbling is mixed into the cooling air 51 to be impinged against the wall surface 5a of the mixing chamber 5. As a result, the temperature and humidity of the formed mixed air 53 can be regulated, by regulating the flow rate of the low temperature cooling air that is humidified, and the flow rate of the bypass air 52 that has the higher temperature than the cooling air.

SOLUTION: An air cooler 4 is constituted of an indirect cooling type with a brine, an air cooler of a refrigerant direct expansion type or the like or an air cycle or the like having an air expansion unit to generate a low- temperature air for cooling to 0 deg.C or lower. A cold water tube 7 connects a bottom of a heat storage tank 1 to a reservoir 11 of an icemaker 10, and a cold water pump 3 provided at the tube 7 sends a cold water (water for icemaking) in the tank 1 to the reservoir 11. An ice conveying tube 8 for connecting an outlet chamber 15 to the tank 1 introduces the ice generated by the icemaker 10 to the tank 1 through the tube 8. Thus, the ice generated by the icemaking is mainly gathered to an upper portion in the tank 1 by its buoyancy.

摘要： PURPOSE:To make ice and capture the same properly and rapidly by cooling water to 0 deg.C or lower with low temperature air upon ice making in ice utilization equipment disposed inside or outside a house. CONSTITUTION:Air is converted to high temperature one by compressing the same into high pressure air (e.g. 2 atom), and the high temperature air is easily cooled to about ordinary temperature utilizing tap water temperature and fresh air temperature. Low temperature high pressure air is yielded by further cooling the ordinary temperature high pressure air with use of the low temperature air after passage thereof through an ice making cold air fan 4. Low temperature air at about -5 deg.C-about -45 deg.C is yielded by expanding the low temperature high pressure air using an expander 3. Ice making is achieved without causing any harmful environmental pollution by bringing the air at 0 deg.C or lower into direct contact with water droplets and a water screen flow. Further, an ice link and an ice course are constructed inside or outside a house by ventilating a cold air pipe buried in the ice link or the ice course with the cold air. Return air after passage through the cold air pipe can be recycled for compression, cooling, and expansion. Hereby, ice making and ice capture are properly and rapidly achieved.
