Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat storage heating and cooling system used in buildings such as general houses and apartment complexes.

Conventional technology Conventionally, for example, in an apartment complex, medium-temperature water of 10 to 25 degrees Celsius is used as the heat medium, and energy is exchanged with the medium-temperature water using water pipes, heat pumps, etc. for each residential unit. A type heating and cooling system is used.

Problems to be Solved by the Invention However, in the above-mentioned conventional system, the building blocks of apartment buildings are made of concrete and have a large heat capacity, so it is difficult to use the conventional intermittent heating and cooling system. , it is necessary to temporarily input a large amount of energy, and the total amount of energy used also increases. Moreover, it is necessary to supply sufficient energy even when the residential unit is used at its maximum load in summer and winter. For this reason, the capacity of the heat storage tank to be installed has to be large, and the amount of water to be conveyed must also be set large, and the water pipes used for water conveyance must be insulated to prevent heat loss during water conveyance. First, there was a problem in that equipment costs increased.

Therefore, the present invention reduces the heating and cooling load by dissipating heat from the walls and floors of the building to the inside, making it possible to downsize the heat storage tank and water supply equipment used for heating and cooling, thereby reducing the burden on equipment. The present invention aims to provide a heat storage heating and cooling device.

Means for solving the problems and the technical means of the present invention for solving the above-mentioned problems are: a heat storage tank; It is equipped with internal piping and a heat medium transport device that circulates the heat medium in the heat storage tank through the pipe, and is configured so that the circulating heat medium stores heat in the outer periphery of the pipe and radiates it into the building. This is what I did.

action The effects of the above technical means are as follows.

The heat medium in the heat storage tank is circulated through the piping by a heat medium transfer device, and the heat is stored in the outer circumference of the pipe, and the heat is radiated into the building through at least one of the walls and the flooring. This makes it possible to partially satisfy the heating and cooling load in the building, reduce the input energy for the heating and cooling load, and prevent the consumption of a large amount of energy in a short period of time. Therefore, it is possible to downsize the heat storage tank and the water supply equipment.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, a first embodiment of the invention shown in FIG. 1 will be described. The interior of this embodiment has an area of 8 tatami mats, the floor 1 and walls 2 are made of a heat storage material made of concrete, and a window 3 fitted with a single plate of glass is formed on the negative side. A water supply pipe 4 for heat source water, which is a heat medium, is buried in the floor 1 and wall 2 in a zigzag pattern, and both ends of this water pipe 4 are connected to a hot water tank 5, which is a heat storage tank, so that the heat source water can circulate. A water pump 6, which is a conveying device for circulating heat source water, is provided in the middle of the water pipe 4. The volume of the concrete heat storage material constituting the floor 1 and walls 2 is set to 32 m3, and the outer walls are sufficiently insulated.

Next, the operation of the above embodiment will be explained based on test results.

First, as a comparative example, in order to maintain the room temperature at 20° C. or higher without flowing heat source water into the water pipe 4 during winter heating, it required 720 C&J 7 days of energy from the indoor heat generating equipment. Also, the peak value for each hour is 8001G, J
It was 7 o'clock. On the other hand, based on the above embodiment, the water pump 6 is driven to flow the 20°C heat source water in the hot water storage tank 5 to the water supply pipe 4 at a rate of 300μ/hour, and the heat storage section on the outer periphery of the water supply pipe 4 is
In other words, when heat is stored in the floor 1 and wall 2, the energy required to maintain the room temperature at 20℃ using the heat generating equipment in the room is 5300 Kt, which takes 17 days, and the hourly peak value is 600 yen. there were.

In this way, by storing heat in the floor 1 and wall body 2, which are the heat storage areas around the water supply pipe 4 that sends heat source water, and radiating the heat into the room, the amount of heat required by the indoor heat generating equipment is reduced, and the heat generation equipment is It has also become possible to reduce the peak heat amount.

Next, a second embodiment of the present invention shown in FIG. 2 will be described. This example is a case of a Japanese house equipped with a flooring material having a space 9 inside the surface 8 of the floor 7. Water pipes 1 are arranged in a zigzag pattern in the space 9, and a heat storage device is placed around the outer periphery of the water pipes 1. 10
The other structure is the same as that of the above embodiment.

It is clear that in this embodiment, by flowing the heat source water through the water supply pipe 4 and storing heat in the heat storage body 10, it is possible to obtain the same effects as in the first embodiment.

Next, a third embodiment of the present invention shown in FIG. 3 will be described. In this embodiment, the water supply pipes 4 are arranged in a zigzag pattern only on the wall body 2 made of heat storage material, and the other configurations are the same as in the first embodiment.

It is clear that in this embodiment, by flowing the heat source water through the water supply pipe 4 and storing heat in the wall 2, it is possible to obtain the same effect as in the first embodiment.

In each of the above embodiments, an example of heating a single-room house during winter is explained, but the same method can be applied to a multi-room house, an apartment complex, etc.

Similar effects can also be obtained during cooling.

In addition, in apartment buildings, the installation location of heat source water piping 1,
By changing the density and heat conduction from the pipe 4 in the heat storage part,
By installing equipment that maintains a constant temperature distribution throughout the housing frame, it is possible to store heat in the frame so that all units have a uniform air conditioning load, which is different from traditional apartment buildings where the air conditioning load varies depending on the location of each unit. Unlike other cities, it is possible to provide homogeneous living conditions. Furthermore, in the present invention, economical efficiency can be improved by constantly supplying energy and storing heat during times when energy is available.

Effects of the Invention As is clear from the above explanation, according to the present invention, piping connected to the heat storage tank is provided inside at least one of the walls and flooring of the building, and the heat medium in the heat storage tank is transported as a heat medium. The heat is circulated by a device, and the circulating heat medium stores heat around the outer periphery of the piping and radiates it into the building. Therefore, the total amount of heat storage can be increased, the heat storage effect can reduce temporary peaks in the heating and cooling load of the building, the heat storage tank and water supply equipment can be downsized, and equipment costs can be reduced.
