Abstract

<P>PROBLEM TO BE SOLVED: To effectively use solar heat and underground heat to adjust residence room temperature. <P>SOLUTION: A concrete tank 24 is embedded into the ground, and a heat exchange pipe 26 is arranged within the concrete tank 24. Inside of the concrete tank 24 is filled with rain water, underground water or running water. In summer, by using storage water 27 within the concrete tank 24 cooled by underground heat, air supply from a total heat exchange type ventilation fan 5 is made to flow via the heat exchange pipe 26 within the concrete tank 24 to send weak cold air to each room, so as to achieve efficient weak cold air operation. In winter, since low temperature hot water within the concrete tank 24 heated by underground heat is circulated in a solar heat water heater 2, the low temperature hot water in the concrete tank 24 is further warmed, and air supply from the total heat exchange type ventilation fan 5 is warmed via the heat exchange pipe 26 within the concrete tank 24, so as to send the warm air to each room. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention stores rainwater, groundwater or tap water in underground concrete tanks, and uses water that is easy to handle and has a large heat capacity as a heat source.In winter, hot water warmed by a solar water heater is used in the ground. In the summer, the water stored in the concrete tank is used, and in the summer, the stored water cooled by underground heat is used, and when the stored water is warmed, the water in the concrete tank is replaced with groundwater to cool it down. The present invention relates to an apparatus for adjusting room temperature by supplying air supplied from a heat exchange type ventilation fan to each room via a heat exchange pipe in a concrete tank.

  Conventional room temperature adjustments for small-scale homes have used air conditioners in the summer and air-conditioning using electricity, gas, oil, and other energy sources in the winter. From the viewpoint, it is an urgent need to reduce CO2 emissions accompanying energy consumption, and reduction of energy consumption and further replacement with natural energy are urgently desired.

  Along with this, as a means of utilizing natural energy, what is currently widely used is a solar water heater (thermal efficiency 50-60%) and solar power generation (conversion efficiency 10-15%) using solar energy. However, in both cases, energy-saving technology that uses only solar energy is easily affected by the weather, and because it is unstable, it cannot be used alone, and has been used in combination with other energy. There is still a need for further improvements.

  On the other hand, the underground 3 to 4 m underground maintains a stable temperature throughout the year, so the temperature in summer is lower than that of outside air and the temperature in winter is higher than that of outside air. For this reason, facilities that use such geothermal heat have been experimentally constructed in large buildings and public facilities, etc., but the method of use is to preserve the ice made in nature during the winter. In general, the ice is transferred to a heat storage tank in the basement in the summer to make cold water, and the cold water is circulated to each room to cool it. The heat storage layer had to be replenished with ice, making it unsuitable for small housing.

Furthermore, a heat pump system that uses geothermal heat is also used to supply hot water in the home and to cool and heat the room, but a horizontal loop system (deep a 1-2 m deep moat in the ground, In order to obtain a heat source for a house with a floor area of 100 m ² , it is necessary to embed a heat collecting pipe of 400 to 600 m, and a vertical loop method (underground) 2) is required for the construction of a well with a depth of 50 to 100m, and a pipe for heat collection is buried there. There was a problem that (electricity bill) took about 75% of electric water heaters using midnight power.

  In July 2003, the Building Standards Law was amended to require 24-hour ventilation of the room (to ventilate 0.5 times the volume of the room in one hour) as a “sick house measure”.

Therefore, the present applicant invented and applied for an “earth / solar system (two-layer type)” described in Patent Document 1 and capable of complying with the Building Standard Law. According to the present invention, two tanks, a water storage tank and a hot water storage tank, are buried in the ground, and heat exchange pipes that communicate with the 24 hour air supply pipes of each room from the outside air intake are provided in both tanks. Plumbing and filling the storage tank with rain water, ground water or tap water, and the storage water tank is filled with hot water from the solar water heater, and by operating the open / close valve provided in the heat exchange pipe, Using the cold water in the water storage tank that has been cooled with cold outside air, the outside air is passed through the heat exchange pipe in the water storage tank, and the hot outside air is cooled and sent to each room, so efficient cold air operation can be performed I can do it. In winter, the warm water in the storage tank heated by the hot outdoor air in the summer is warmed to the low-temperature water in the storage tank via a heat exchange vapor, and the hot water in the hot water tank using a solar water heater is used. Since it passes through the heat exchange pipe, it becomes possible to send warm air into each chamber.

  First, a method for supplying water to the concrete tank 24 and the solar water heater 2 will be described. First, the open / close valve 80 for water supply / stop is closed, the open / close valve 77 for water supply / stop is opened, and the air vent valve (not shown) of the solar water heater 2 is opened. Further, by opening the open / close valve 79 for supplying and stopping water at the same time as driving the water supply pump 78, water is sent in the direction of arrow 76 from the water supply pipe 91 connected to the underground water supply pipe 92. It is sent from the direction of arrow 71 to the direction of arrow 69 via 73, and is supplied to the solar water heater 2. And after the solar water heater 2 is filled with water, the air vent valve (not shown) of the solar water heater 2 is closed. In this way, the water filling the solar water heater 2 flows in the hot water pipe 74 from the direction of the arrow 68 in the direction of the arrow 72, flows in the direction of the arrow 32 via the hot water pipe 88, and fills the concrete tank 24 with water. . After the concrete tank 24 is filled with water in this way, the water supply pump 78 is stopped, and the open / close valve 79 for supplying and stopping water is closed.
