摘要： PROBLEM TO BE SOLVED: To provide a thermal storage type vehicular air conditioner keeping interior temperature during traveling constant, efficiently storing cold, and using the cold as an auxiliary cooling device for suppressing a temperature rise in the vehicular interior during idling. SOLUTION: An evaporator and a thermal accumulator are connected in series as a coolant flow path, and a vehicular interior is successively air- conditioned during traveling, thereby suppressing rising/lowering of vehicular temperature. Excessive cold obtained by deducting a vehicular interior load from cooling performance generated by successively operating an air conditioner is stored. During idling, the cold is dissipated to use for an auxiliary cooling device, thereby suppressing a temperature rise in the vehicular interior. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To shorten the ice making time by jointing heat exchanging heating tubes arranged in parallel with the bottom face of an ice heat storage tank to fins excellent in thermal conductivity and contributive to ice making while penetrating the fins such that the fins are substantially perpendicular to the bottom face of the tank. SOLUTION: An ice making heat exchanger comprising finned pipes 1 is employed in an inner melting type ice heat storage air conditioner. The ice making heat exchanger comprising finned pipes 1 is jointed with pipes 1 for passing the cooling refrigerant from a refrigeration cycle while penetrating the fins 2 and the pipes 1 are arranged such that the fins 2 are substantially perpendicular to the bottom face of the heat storage tank. Since the heat transfer area of the ice making heat exchanger can be increased in correspondence with contribution of the fins 2 to ice making, flow rate of the cooling refrigerant in the pipe 1 can be increased resulting in an increase in ice making quantity.

摘要： PROBLEM TO BE SOLVED: To obtain an ice making apparatus with a compact structure which enables conserving of an installing space and construction cost by reducing the interval between an ice making panel and a crusher while completely preventing a stress from a raking device and the crusher from acting on the ice making panel without decreasing the ice making capacity of a harvest type ice making apparatus. SOLUTION: Cutters 6a and 6b as crushing means are disposed at parts right below respective ice making panels 1 or in a sharable range between the adjacent ice making panels 1. Ice 3 separated from the ice making panel 1 is crushed into desired size of pieces without being gathered to one location in the process of being caused to drop to a heat storage tank provided there below. A mechanism 7 to keep the crushing force of the cutters 6a and 6b from directly working on the ice making panel 1 during crushing and a mechanism 8 to block the uncontrollable action of ice are provided to protect the ice making panel 1 from destruction or deterioration in a long period of time.

摘要： PROBLEM TO BE SOLVED: To improve thawing performance at the time of heat radiation, resolve the situation wherein ice is hung up and hardly falls at the time of ice removal from an ice-making plate and solve the problem that detached ice is apt to stay in a lower part of an ice making section and is difficult to diffuse into a tank, in a thermal storage system. SOLUTION: Water in a tank 52 is guided to a radiator 12 through a pipe 8B, a valve 15 and a pipe 13C by a pump 6 at the time of radiation and then is sprayed into the tank 52 through a manifold 3 and a spray pipe 2. By these steps, ice 51 in the tank 52 is thawed and spray water is cooled. The cooled water is made to flow into the radiator 12 again by the pump 6. Part of the water 50 is returned to the tank 52 via a pipe 18A from the pump 6. The ice 51 is stirred by this water so that thawing speed is accelerated. The ice 51 is relieved from staying and being stacked under an ice making section 1. When ice growing on an ice making plate is detached, hot gas is made to flow in every other ice making plate to detach the ice and detaching ice density is reduced so as to prevent the ice from being hung up between the neighboring ice making plates.

摘要： PROBLEM TO BE SOLVED: To provide means in which non-utilized heat such as solar heat incident to a southern side of a building or a discharged heat from a factory is effectively utilized as one for heating a northern side of the building and the other for heating an entire inner side of the building at night without performing a large-scaled reforming in the building or increasing a system. SOLUTION: Solar heat incident to a southern side of a building or a discharged heat from a factory is easily stored at a mobile heat storing device 1 which can be moved through wheels or along rails. In order to apply this heat as a heating system for the northern side of the building or during a time ranging from evening to night, the device is utilized as a heating system while it is moved to a place where the heating heat is required and heat is easily radiated.
