摘要： PURPOSE:To prevent quantity of a coolant circulating along a coolant circuit from decreasing by providing solenoid valves at the front and rear stages of an evaporator circuit and also providing a control circuit for operating these solenoid valves and carrying out the pumping down of the evaporator circuit on the side not utilized. CONSTITUTION:The heat pump device comprises solenoid valves 14c, 14d, 15c and 15d which are provided respectively at the front stages and the rear stages of evaporator circuits C and D and open and close the evaporator circuits C and D, and a control circuit for operating these solenoid valves and carrying out the pumping down of the evaporator circuit or the side not utilized. According to this structure, during the stoppage of the heat pump device, all the solenoid valves 14c, 14d, 15c and 15d are closed. Therefore, it is possible to reduce the quantity of the coolant moving to evaporators 13c and 13d. Further, at the time of starting the heat pump device, the solenoid valves 14c and 15c of the circuit C of the utilizing side evaporator 13c are closed and the solenoid valves 14d and 15d are opened. Thus, the coolant flows to the evaporator 13d on the side not utilized. After operating for a predetermined time, the solenoid valve 15d is closed, and the solenoid valve 14c and 15c are opened and the evaporator 13d stands still and an operation utilizing the evaporator 13c is carried out. Consequently, the evaporator 13d can recover the stored coolant and the freezer oil.

摘要： PURPOSE:To transfer the waste heat of a condenser directly to an evaporator and permit the cooling of the condenser by the evaporator, by a method wherein heat exchange between the condenser of an air conditioner and the evaporator of a heat pump is effected through not only air but also solid material. CONSTITUTION:In a heat exchanger 13, waste heat from the refrigerant of an air conditioner 14 is transferred to the refrigerant of a heat pump 17 through not only air, sucked into an air introducing passage 20, but also a solid material or heat transfer fins 21 whereby heat exchange between the condenser 15 of the air conditioner 14 and the evaporator 18 of the heat pump 17 is effected efficiently. Accordingly, the evaporating temperature of the refrigerant of the heat pump 17 is increased and the efficiency of the heat pump 17 may be improved remarkably while the removal of heat from the condenser 15 of the air conditioner 14 or the cooling of the condenser 15 is effected effectively and the condensing temperature of the refrigerant of the air conditioner 14 is reduced whereby the efficiency of the air conditioner 14 may be improved remarkably.

摘要： PURPOSE:To increase shearing intensity of a sediment, so as to prevent landslide when an artificial hill is formed by banking so as to cover a public system, by laying a geotextile between the respective bankings, and utilizing an interlock effect. CONSTITUTION:After a public system S such as a road 5 or a railroad 6 is laid on a ground surface G, a ground on the side of the public system S is dug up so as to form a recessed part 9, and the excavated sediment is raised around the public system S as a banking 11. After a net-shaped geotextile 10 is laid so as to cover the upper part of the banking 11, a banking 12, a geotextile 13, and a banking 14 are further laid thereupon for finishing. Due to the elevation of an interlock effect between the banking 12 and the geotextile 10, shearing intensity of the sediment is increased, whereby landslide of a banking can be prevented.

摘要： PURPOSE:To curtail the cost of construction work by a method in which a cylindrical outer wall, a bottom slab covering the bottom of underground space surrounded by the outer wall, and a top slab covering the upper opening are formed under the ground, and the outer wall is made up of a deck plate and soil concrete layer. CONSTITUTION:A trench 2 is excavated to a given depth in the ground G where an outer wall is to be constructed, and the excavated soil is mixed with cement milk S. Before the soil concrete hardens, a deck plate 3 is penetrated into the trench 2. The trench 2 is surrounded by the plate 3 over the whole length of the trench 2 to form the outer wall of concrete layer a, and after the layer A hardens, the inside ground G is excavated. After the excavation, water-proof concrete is placed to the bottom to integrate the plate 3 with the bottom slab 10, and a deck plate 20 for the first floor is set above the wall plate 3 to cover the upper opening of the underground space to form a top slab 30. The construction procedure can thus be simplified.

摘要： PURPOSE:To make it possible to miniaturize the heat exchanger and prevent ice from attaching thereto without degrading the heat exchange function thereof by generating a water flow in the inner part of the heat exchanger thereby exfoliating ice attached to the inner surface of the heat exchanger. CONSTITUTION:A screw 8 is supported rotatably within a heat exchanger 3, and a coating layer made of tetrafluoroethylene or the like, degrading the adhesive force of ice onto the inner surface of the side wall part 3a, facilitating exfoliation of ice from the inner surface of a side wall part 3, is provided on the inner surface of the side wall part 3a. A face heater is provided on the inner surface of the side wall part of the heat cxchanger 3. The heat exchanger 3 is disposed in a heat storage tank 1, and simultaneously with the starting of the forced circulation of an antifreezing solution, power water is delivered under pressure and supplied to a hydraulic turbine 10 by a pump. By these procedures, the screw 8 within the heat exchanger 3 is rotated in one direction, and hence water flow is generated in one direction within the heat exchanger 3.
