BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating / cooling system capable of efficiently realizing an ergonomically most ideal living space as head cold foot heat.

[0002]

2. Description of the Related Art Conventionally, when controlling the room temperature of a living space, an air conditioner such as a cooler is used in the summer and a heater such as a stove is used independently in the winter.
It is common to use an air conditioner.

[0003]

As for the temperature distribution in the same space in the natural world, the temperature becomes higher from the lower part to the upper part, and the upper part in the space is usually warmer than the lower part. . Therefore, when using the air conditioner in the summer, the temperature of the head becomes warm while the feet are excessively cooled, and the dirty air in the room stagnates at a low position. Not only is it often caused, but also so-called air-conditioning diseases such as coldness and tiredness are often caused. On the other hand, when using a heater such as a stove or an air conditioner in the winter season, warm air rises near the ceiling as shown in the temperature distribution in the natural world. Since it stays in a lower position, it is not only unhealthy and causes discomfort, but also has a problem that the feet are always cold.

By the way, when considering air conditioning ergonomically, it is most preferable to keep the head cool and the feet warm, that is, to have a cold head and foot heat. Applying this to the conventional air conditioning system, it is completely different from the ideal system of head cold foot heat not only in winter but also in summer.

The present invention has been developed in view of such problems, and a comfortable living space is provided by appropriately heating the lower portion of the living space to a proper temperature through the heat exchanger with the amount of heat recovered by the air conditioner. Is obtained, and moreover, it consumes only the minimum amount of energy required and is extremely economical.
It is intended to provide a heating / cooling system that can provide an environment of head-and-foot heat throughout the year.

[0006]

In order to achieve the above object, the present invention provides a heating / cooling system having an air conditioner in the upper part of a living space and a heater in the lower part, and the amount of heat recovered by the air conditioner is The heat transfer drive source is used to move the heat transfer drive source, and the heat pump evaporation unit side and the air conditioner are connected by a refrigerant circuit composed of a closed brine, and the heat pump condensation unit side and the heat exchanger are closed brine. Floor heating by connecting the heat exchanger and the floor heater embedded in the floor with a heat medium circuit consisting of closed brine, and arranging this heat medium circuit on the floor. The floor heater is configured to heat the lower part of the living space by the radiant heat radiated by the floor heater. The above-mentioned air conditioner is configured to cool by the heat of melting of ice by the ice heat storage device. The above heat exchanger is preferably provided with an auxiliary heat source that is a boiler, and is also provided with a hot water supply pipe and a bathtub heating pipe. Furthermore, a system having a structure in which a circulation pump is provided in each of the refrigerant circuit and the heat medium circuit is preferable.

[0007]

With this structure, the upper part of the living space is cooled to an appropriate temperature by the air conditioner, and the heater heats the amount of heat recovered from the air conditioner as a heat source to the radiant heat of the floor heating, that is, the air conditioner. By exchanging heat between the heater and the heater, a head cold foot heat environment can be obtained throughout the year. In this case, for the coefficient of performance of floor heating, the heat obtained by cooling and the heat of the drive source that moves this heat can be added to use effective heat, and a system that contributes to energy saving can be obtained. And is extremely economical.

The heat pump 7 is connected via the compressor 21.
The condensing part side 16 and the heat exchanger 8 are connected by a heat medium circuit (outgoing pipe) 17 and a heat medium circuit (return pipe) 18 made of a closed brine. The heat exchange sections 17a of the heat medium circuits 17 and 18 are provided, and the circulation pump 20 is provided in the middle of the heat medium circuit 17. Further, the heat exchanger 8 and the floor heaters 10 and 11 embedded in the floor 23 are connected by the heat medium circuits 12 and 13 made of closed brine, and the heat medium circuit in the heat exchanger 8 is the heat exchange unit 8a. And the heat medium circuits 12 and 13 in the floor 23.

a, 11a, and the heating medium conduits 10a, 11a constitute a floor heater. Further, the heat exchanger 8 is provided with an auxiliary heat source 24 which is a boiler, and when a large amount of heat is consumed by hot water supply or the like, the boiler 24 is used as an auxiliary.
Further, the heat exchanger 8 includes a hot water supply pipe 14 and a bathtub heating pipe 2.
5 is provided to supply hot water.

In this embodiment, it is preferable to use a floor heating unit for the heaters 10 and 11 by radiant heat using a hot water pipe as shown in Japanese Utility Model Publication No. 59-16730. Further, although not particularly shown, the coolers 3 and 4 and the heaters 10 and 11 are controlled by a control mechanism using various sensors so that a comfortable environment is always obtained.
For example, in the summer, the cooling is strengthened and the heating is weakened, and in the winter, the heating is strengthened and the cooling is weakened, so that the cooling power and the heating power are balanced.

The present embodiment configured as described above has the following operation. First, the refrigerant cooled on the evaporator side 15 of the heat pump 7 passes through the refrigerant circuit 5 and the cooler 3,
The air is supplied to the air conditioner 3 and the air in the rooms 1 and 2 is exchanged with the refrigerant in the air conditioners 3 and 4 to cool the room. In this case, if the ice in the ice heat storage device 9 is formed by inexpensive electric power such as midnight electric power, cooling can be performed by the heat of melting of the ice during cooling, which is more economical. As described above, the warmed refrigerant having the amount of heat taken from the upper spaces of the rooms 1 and 2 is returned to the evaporator side 15 of the heat pump 7 through the refrigerant circuit 6 by the air conditioner to accelerate the evaporation of the heat pump 7, Next, the compressor 21 of the heat pump 7

Will effectively dissipate the heat. As described above, the recovered heat is not released to the atmosphere, waste heat is recovered by the heat exchanger 8, and the heat exchanged here is transferred to the heaters 10 and 11 via the heat medium circuits 12 and 13. Heating is performed by heat exchange between the air and the heat medium in rooms 1 and 2,
The heat medium that has been heat-exchanged with the air of 2 is returned to the heat exchanger 8 through the heat medium conduit 13.

In this case, since the temperature is high in the summer, the operation rate of the heat pump described above also increases, and the amount of heat sent to the heat exchanger 8 also becomes a considerable calorie. On the other hand, for the heating used in the summer, the amount of radiant heat is sufficient to obtain the warmth that prevents the body from becoming too cold, and the heat exchanged by the heat exchanger 8 may not be completely consumed. Therefore, in this embodiment, hot water is supplied to the bath, sink, etc. by connecting the hot water supply pipe 14 to the heat exchanger 8.
Then, only the surplus amount of heat is released into the atmosphere.

[0012]
