Abstract

PURPOSE:To provide an economically excellent system capable of creating a 'keep one's head cool and feet warm' environment throughout the year by driving both a chiller and a heater simultaneously. CONSTITUTION:When driving chillers 3 and 4, the heat value prevailing in the upper part of a room is collected by a refrigerant cooling unit (heat transfer drive source). This heat value is exchanged by a heat exchanger 8 where it is possible to obtain comfortable heating/cooling system by heating the lower part of a room with radiation heat of floor heaters 10 and 11, using the exchanged heat.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and cooling system that can efficiently create a living space that is ergonomically ideal for keeping the head and feet warm.

0002

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

0003

[Problem to be solved by the invention] In the natural world, the temperature distribution within the same space is such that the temperature increases from the bottom to the top, and the upper part of the space is usually warmer than the lower part. . Therefore, when using an air conditioner in the summer, while your feet get excessively cold, your head gets warmer, which causes the dirty air in the room to stay at a lower level, making you feel uncomfortable when you are indoors. Not only this, but it also often leads to so-called air conditioning sickness, such as sensitivity to cold and fatigue. On the other hand, when using heaters such as stoves and air conditioners in winter, all of the warm air rises near the ceiling, as seen in the temperature distribution in the natural world above, and the dirty air inside the room is transported to the intermediate space. Because they stay in a lower position, they are not only unhealthy and uncomfortable, but also have the problem that their feet are always cold.

[0004] When considering air conditioning from an ergonomic point of view, it is considered most desirable to keep the head cool and the feet warm, that is, to keep the head cold and the feet warm. When we apply this to conventional air conditioning systems, we find that it is far from the ideal system that keeps the head cold and the feet warm, not only in the winter but also in the summer.

[0005] The present invention was developed in view of the above problem, and provides a comfortable living space by heating the lower part of the living space to an appropriate temperature via a heat exchanger using the heat recovered by the air conditioner. Moreover, it is extremely economical as it only requires consuming the minimum amount of energy necessary.
It provides a heating and cooling system that provides an environment where your head is cold and your feet are warm throughout the year.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a heating and cooling system that includes an air conditioner in the upper part of a living space and a heater in the lower part. A configuration was adopted in which the lower part of the living space is heated to an appropriate temperature and the upper part is cooled by moving the heat by a heat transfer drive source and using this transferred heat as a heat source for the heater via a heat exchanger. The above-mentioned heater preferably uses a floor heater having a structure in which hot water pipes are buried in the floor, and uses radiant heat emitted by the floor heater to heat the lower part of the living space. Further, it is preferable that the heat transfer drive source uses a heat pump to transfer the amount of heat recovered by the air conditioner to a lower part of the living space. Furthermore, it is preferable that the air conditioner has a structure in which cooling is performed using heat of melting ice produced by an ice heat storage device.

[0007]

[Function] With this configuration, the upper part of the living space is cooled to an appropriate temperature by the air conditioner, and the heater uses the heat recovered from the air conditioner as a heat source and warms it to the appropriate temperature by radiant heat from the floor heating, that is, cooling. By mutually exchanging heat between the container and the heater, an environment that keeps your head cold and your feet warm throughout the year can be achieved. In this case, the coefficient of performance of floor heating is that the heat acquired by air conditioning is added to the heat of the drive source that transfers this heat, and effective heat can be used to obtain a system that contributes to energy savings. It is extremely economical.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a heating and cooling system according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the system configuration of a heating and cooling system. Rooms 1 and 2 are provided with air conditioners 3 and 4 installed on the ceiling of each room, which are connected to refrigerant pipes 5 and 6. and is connected to a refrigerant cooling unit (heat transfer drive source) 7. This heat transfer drive source 7 uses a heat pipe in this example. Further, 8 is a heat exchanger for using the heat obtained from the heat pump 7 as a heat source for hot water used in the heaters 10 and 11, and is a heat exchanger that is buried in the floor of each room by heat medium pipes 12 and 13. It is connected to heaters 10 and 11.

In this embodiment, the above-mentioned refrigerant cooling unit 7 uses an ice heat storage device as shown in Japanese Patent Application Laid-open No. 58074/1982, and the heaters 10 and 11 use
Preferably, a radiant underfloor heating unit using hot water pipes is used, as shown in US Pat. No. 6,730. Also, although not particularly shown, these air conditioners 3 and 4
The heaters 10 and 11 are controlled by a control mechanism using various sensors, so that a comfortable environment can be obtained at all times. etc., to balance cooling and heating power.

The present embodiment configured as described above has the following effects. First, the refrigerant cooled by the refrigerant cooling unit 7 is supplied to the air conditioners 3 and 4 through the refrigerant pipe line 5, and the air conditioners 3 and 4 perform cooling by heat exchange between the air in the rooms 1 and 2 and the refrigerant. The heated refrigerant having the amount of heat removed from the space above the rooms 1 and 2 flows back to the refrigerant cooling unit 7 through the refrigerant pipe 6. At this time, in order to cool the refrigerant, a heat pump, which is one of the components of the refrigerant cooling unit 7, is used to compress the refrigerant.
In the present invention, the heat obtained here is not released into the atmosphere, but waste heat is recovered by the heat exchanger 8. The heat recovered here is heat exchanged with the water used in the heaters 10 and 11, and the water becomes hot water, which is passed through the heat medium pipe 12 to the heaters 10 and 11.
1, and these heaters 10 and 11 perform heating by heat exchange between the air in rooms 1 and 2 and the heating medium, and
The heat medium cooled by the air passes through the heat medium pipe line 13 and returns to the heat exchanger 8.

[0011] In this case, since the temperature is high in summer, the operating rate of the heat pump described above is also high, and the amount of heat sent to the heat exchanger 8 also becomes a considerable amount of calories. On the other hand, in heating used in the summer, the amount of radiant heat is sufficient to provide enough warmth to prevent 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. Only the remaining heat is released into the atmosphere.

0012

[Effects of the Invention] As is clear from the above explanation, the present invention effectively utilizes the heat recovered by the air conditioner to warm the lower part of the space, so almost no energy is required for heating, and the system Overall, this heating and cooling system is not only comfortable, but also very useful from a health perspective, as energy costs are kept very low. Furthermore, this configuration, which allows a luxurious environment with a cold head and warm feet throughout the year while saving energy, can provide a heating and cooling system that is compatible with the trend towards luxury that has been seen in recent years, that is, has a very high marketability.
