Abstract

PURPOSE:To effectively store heat and dissipate stored heat by effectively utilize unused space of a building. CONSTITUTION:The air conditioner comprises a heat reservoir 1 installed under a roof or a space under a floor and heat insulated at an outer surface, a heat source 6 for supplying cold or warm heat to the reservoir 1, and a radiator 8 for removing heat from the reservoir 1 and radiating it. Cold/warm air is supplied from the reservoir 1 to a radiator 8 of a habitable room side in response to a cooling/heating load of the room. Thus, a piping is simplified to effectively utilize stored heat.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a heat storage unit whose outer peripheral surface is heat-insulated by utilizing a space under the ceiling or under the floor, and stores heat or cools it from a heat source, and stores the heat storage unit according to the heating and cooling load of a living room. The present invention relates to an air conditioner adapted to supply cold heat or warm heat to a living room.

[0002]

2. Description of the Related Art Conventionally, a heat storage type air conditioner is dug under the floor or under the floor and laid with heat storage material such as pebbles, or a tank is installed outside the building to store an electric heater and solar heat energy, which is stored in the living room. Pipes are connected to the heat radiating section to heat and cool the living room as needed.

[0003]

In such an underfloor installation type, the size of the equipment is increased, the heat storage rate is poor, the amount of energy that radiates naturally is large, and the effective utilization rate is low. Moreover, if the heat storage section is separately installed outdoors, a space for installing the heat storage section is required, and the piping becomes complicated.

An object of the present invention is to effectively utilize an unused space in a building and to effectively store heat and dissipate this heat.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a heat storage section installed in a space under the ceiling or under the floor and having an outer surface insulated, and to this heat storage section. It consists of a heat source part that supplies cold or warm heat and a heat radiation part that takes out heat from the heat storage part and radiates it.Cold and warm air is supplied from the heat storage part to the heat radiation part on the room side according to the heating and cooling load of the room. Is the gist.

[0006]

[Function] An insulated heat storage unit is provided in the space above the ceiling or under the floor, and heat is stored or cooled by a heat source provided inside or outside the heat storage unit, and then the heat storage unit cools or heats the room according to the heating and cooling load of the room. To supply. For this reason, the piping is simplified and the heat storage can be effectively used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The air conditioner of the present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 denotes a heat storage unit having a size capable of storing a required amount of energy, and the outer surface thereof is covered with a heat insulating material 11. This heat storage unit 1 is shown in FIG. 2 or, as shown in FIG. 2, it is installed in the space on the ceiling 3 on the first floor side or the space under the floor 4 as shown in FIG. The heat storage unit 1 is filled with water or another substance as a heat storage material so as to store hot or cold energy.

If necessary, a heat exchanger 5 is arranged in the heat storage unit 1 and is connected to the heat storage unit via a pipe 7 from a heat source unit 6 separately provided, and energy supplied from the heat source is supplied to the heat storage unit. The heat source 6 is installed on a veranda or the like.

As the heat source 6, an outdoor unit of a heat pump type, an electric heater type warmer that uses late-night electric power or the like to store heat is used, and solar heat energy is used. Further, when the heat source unit 6 is an electric heater type warmer that uses late-night power, and when the heat storage unit stores thermal energy, it can be installed in the heat storage unit.

The heat radiating portion 8 is composed of a heat exchanger 81 and a fan 8
2, a suction / exhaust duct 83, etc., which is installed behind the ceiling as shown in FIG. 1 or in the living room R as shown in FIG. It is connected by a pipe 9 having P.

Further, as the heat radiating portion 8, a convection type air conditioner or heater conventionally used can also be used. Further, the heat radiating unit 8 may be installed in one living room or in two or more living rooms depending on the capacity of the heat storage unit 1 so as to radiate heat simultaneously or selectively.

If the heat radiating portion 8 is also used as a convection type air conditioner, it is possible to assist the rise of the radiant air conditioner, so that cold air or hot air is blown at the same time when the air conditioner starts operating.
It can be cooled or heated in a very short time.

In the above embodiment, the heat radiating portion 8 uses the heat energy from the heat storage portion 1 by exchanging heat with the air in the living room via the heat exchanger in the heat radiating portion, but as shown in FIG. If the unit is installed directly on the floor surface, radiant floor heating can be performed without using a heat exchanger or a fan.

[0014]

The air conditioner of the present invention has a heat storage section installed in the space above the ceiling or under the floor and having an outer surface insulated.
It consists of a heat source that supplies cold or warm heat to this heat storage unit and a heat radiation unit that takes out the heat from the heat storage unit and radiates the heat. There are advantages such as effective use of the usage space and simple piping work.
