摘要： PURPOSE:To increase the heat storage efficiency of the floor heating device and to carry out the floor heating economically and efficiently in a cold district by combining foundation concrete of a sensible heat storage body with latent heat storage bodies consisting of a latent heat storing materials. CONSTITUTION:The heat storage type floor heating device 1 is installed at the floor part 2 of a building and consists of a foundation 3, a heat insulating material 4 and foundation concrete 5, first and second heat equalizing plates 6A and 6B, a plurality of heat generating wires 7, a plurality of latent heat storage bodies 8, and a finishing mortar 10. The quantity of heat generated from heat generating wires 7 is increased in its heating efficiency by the first and second heat equalizing plates 6A and 6B and is transmitted to the foundation concrete 5 and the latent heat storage bodies 8 wherein heat is stored. The quantity of heat stored is radiated equally by the first and second heat equalizing plates 6A and 6B. Dispersion of heat to the ground surface 11 and the side surface of the floor part 2 is prevented by heat insulating materials 4 and 17. Further, the temperature difference between the upper and lower surfaces of the heat insulating material 4 is decreased by a moisture-proof sheet 14, and hence dew condensation can be prevented. Within the finishing mortar 10 a plurality of iron reinforcing bars 15 are incorporated, and hence it is possible to increase the strength of the finishing mortar 10 and to reduce the thickness of the device.

摘要： PURPOSE:To enhance the regenerative efficiency by setting, in piling regenerative containers for the use, the parallel side plates of each unit horizontally and by putting the tubular members of the units out of alignment with each other vertically. CONSTITUTION:Each unit of regenerative containers is provided with a hollow ring- shaped receptacle for seed crystals whose inside diameter is larger than the periphery of the main body, the main body and the receptacle being arranged concentrically and substantially on a common plane, and with a ring-shaped passageway by which the outer periphery of the main body and the inner periphery of the receptacle for seed crystals are connected and communicate. Two through tubes 6c are passed through each regenerative container at points other than the center O, and any two units laid adjacently to each other vertically are arranged out of alignment, one shifted by an angle of 90 deg. from the other around their vertical central axis. As a result, the hot medium flows as shown by arrows a, a', b, b', c, c', d, d' and e, e' so that it comes in even contact with the heating surfaces of the main bodies 6 of the regenerative containers as if flows past them. With the tubular members arranged out of alignment, the hot medium follows a zigzag course so as to heat all of the heating surfaces of the regenerative containers.

摘要： PURPOSE:To make a device serve a double purpose of cooling and heating and to improve usability thereof by incorporating a four-way selector valve and a heat exchanger into a refrigerant circuit, and by producing circulation by a circulating pump through a circuit connecting the heat exchanger and a snow-melting panel. CONSTITUTION:A four-way selector valve 9 for switching the direction of flow for refrigerant gas and a heat exchanger 8 controlling air conditioning at the inside of a room are incorporated into a refrigerant circuit. Then circulation through a circuit connecting the heat exchanger 8 and a snow-melting panel 5 is made by a circulating pump 10. During the wintertime, the snow-melting panel 5 is put into operation, while the device is run for heating operation. In the summertime, cooling operation is made possible by switching the direction of flow of the same refrigerant, while using the snow-melting panel 5 as a radiator.

摘要： PURPOSE:To prevent an excess current from flowing to a switch at the time of switching power sources by switching a switch connected to an AC power source and a switch connected to a DC power source in a no current state. CONSTITUTION:When a DC power source 3 is not started, its state is judged by a controller 11 to close a switch 2. In this case, the output of an AC power source 1 is supplied to an inverter 6 through a power reactor 5. When the power source 3 is started in this state, the inverter 6 is stopped by the controller 11. After the switch 2 is opened, a switch 4 is closed to supply the output of the power source 3 to the inverter 6. When the power source 3 is stopped, the inverter 6 is stopped, the switch 4 is opened, and the switch 2 is closed to supply the output of the power source 1 to the inverter 6.

摘要： PURPOSE:To prevent an excess current from flowing to a switch and an excess load from being applied to a compressor by switching a switch connected to an AC power source and a switch connected to a DC power source in a no current state, and stopping An inverter when a DC voltage value exceeds a predetermined value. CONSTITUTION:When a DC power source 3 is not started, its state is judged by a controller 11 to close a switch 2. In this case, the output of an AC power source 1 is supplied to an inverter 6 through a power reactor 5. When the power source 3 is started in this state, the inverter 6 is stopped by the controller 11. After the switch 2 is opened, a switch 4 is closed to supply the output of the power source 3 to the inverter 6. On the other hand, when the detected value of current detector 12, the inverter 6 is stopped.

摘要： PURPOSE:To shorten the time for discharging the latent heat, to make it easy to separate the hot medium from the cooling fluid, and, moreover, to allow the containers to be piled when used by forming a hollow ring-shaped receptacle for seed crystals whose outside diameter is smaller than the inside diameter of the main body of a regenerative container and by making the main body and the receptacle connected and communicate by a hollow ring-shaped passageway. CONSTITUTION:The hollow disk-shaped main body 6 of a regenerative container and a hollow ring-shaped receptacle 7 for seed crystals whose outside diameter is smaller than the main body are concentrically arranged substantially on a common plane and connected by a hollow ring-shaped passageway 8. The main body 6 of the regenerative container is packed with a regenerative material 2. At a part of the regenerative material a receptacle 7 for seed crystals is filled so that, upon cooling, the contents crystallize into seed crystal 4. The regenerative material 2 is in contact with seed crystals 4 at all points along its inner periphery and, when the heat is released, the crystals are allowed to grow by only short distances in the paths of their growth; therefore, the latent heat can be discharged in a short time. The regenerative containers can be joined in a pile by means of short cylindrical supporting rings 9.

摘要： PURPOSE: To decrease the number of operation and the quantity of snow dropped, and to reduce cost and lengthen a lifetime by setting a space between a roof surface and a snow removing member at a specified value and at a value or less corresponding to the quantity of a snow cover on a roof in a limit, in which a building can resist safely. CONSTITUTION: Snow removing members 6 fixed into trucks 8 through L-shaped connecting members 10 are bridged between guide rails 3, 3 installed on both sides of the gable side of a roof 1 through mounts 11 for heap up in 25 cm while being crossed over the rails 3 and being extended even to the gable side. Spaces in approximately 30 cm obtained by adding the height of the mounts 11 to spaces in approximately 5 cm among the conventional roof 1 surface and the snow removing members 6 are set in the quantity of a snow cover or less in a limit, in which the roof 1 can resist safely at that time. A person expects to a snowmelt by sunshine at daytime in sections of 30 cm left by snow dropping by driving the snow removing members 6 when the quantity of the snow cover reaches approximately 30 cm or more, and snow can be dropped extending over the whole surface of the roof 1 by the snow removing members 6 when the quantity of the snow cover exceeds 30 cm by a snow fall again.
