を生じるという問題がある。 This idea took into account the excellent performance of the ice heat storage tank, and created a system that allows it to function satisfactorily not only during cooling but also during heating. The problem here is that if we try to take full advantage of the fact that the ice heat storage tank is superior in storing cold heat, there is a risk that the ice heat storage tank will lack the ability to store cold heat during heating. The point is that there is.
In other words, compared to a heat storage tank that stores cold heat in the form of water, an ice heat storage tank can store a large amount of cold heat corresponding to the solidification heat of ice, and as a result, the capacity of the ice heat storage tank itself can be reduced. It has a good quality. However, on the other hand, during heating, the ice heat storage tank has a small capacity, so it cannot store a large amount of hot water, and there is a problem that the amount of heat stored is small, resulting in a lack of capacity.

(In some cases, this can be simplified by using a 4-way valve.)
It is selectively and reversibly circulated between two of them as appropriate. There are two forms: one in which the circulation is reversible between the first heat exchanger 1 and the second heat exchanger 2, and the other in which the circulation is reversible between the second heat exchanger 2 and the ice heat storage tank 4. There are two modes: one in which the ice is circulated reversibly between the ice heat storage tank 4 and the first heat exchanger 1.

c is opened and the other on-off valves are closed, and the heat medium from the compressor 3 circulates through the first heat exchanger 1, the expansion valve 6a, and the ice heat storage tank 4 in this order. Therefore, the first heat exchanger 1 acts as a condenser and radiates heat, while the ice heat storage tank 4 acts as an evaporator and absorbs heat. As a result, the ice heat storage tank 4 makes ice therein and efficiently stores a large amount of cold heat. Since the amount of heat stored is large, a small capacity ice heat storage tank 4 is sufficient. In addition, in such a heat storage state, the room is cooled by heat exchange between the ice heat storage tank 4 and the air conditioner of the room (not shown).

Thereby, the second heat exchanger 2 cools the room by exchanging heat with the air conditioner of the room (not shown). Further, at this time, the cold energy stored in the ice heat storage tank 4 is also used for cooling the room. As a result, the load on the second heat exchanger 2 is reduced, and power consumption is kept low.

分に対応することができる。 In the morning when the load is heavy during the heating season, the room is heated by heat exchange with the room's air conditioner (not shown), using the hot water stored at high temperature during the night to a usable temperature. The remaining heat stored in the ice heat storage tank 4 is used to heat the room by the heat dissipation action of the second heat exchanger 2. In other words, 3 shown in the figure
When the three on-off valves 5i, 5k, 5b, and 5c are open and the other on-off valves are closed, the heat medium from the compressor 3 is transferred to the second heat exchanger 2, the expansion valve 6a, and the other on-off valves.
The ice is circulated sequentially through the ice storage tank 4. Therefore,
The second heat exchanger 2 acts as a condenser and radiates heat, while the ice heat storage tank 4 acts as an evaporator and absorbs heat. Thereby, the second heat exchanger 2 heats the room by exchanging heat with the air conditioner of the room (not shown). As a result, compared to using heat exchanger 1 to absorb heat, the second heat exchanger 2 becomes more efficient and the output increases significantly.
Power consumption can be kept low compared to the amount of heat used. Furthermore, heating by using the ice heat storage tank 4 and the second heat exchanger 2 in combination is extremely advantageous in reducing the capacity of the ice heat storage tank 4 by taking advantage of its superiority in cooling. In other words, although it is possible to reduce the capacity of the ice heat storage tank 4 due to its superiority in terms of storing cold heat during the cooling season, it is possible to reduce the capacity of the ice heat storage tank 4 from the point of view of storing warm heat during the heating season. There is a risk that there will be a shortage,
In this respect, being able to widen the usage temperature range of the ice heat storage tank 4 during the heating season and ensure high output with high efficiency makes up for the lack of capacity and output of the ice heat storage tank 4 during heating. becomes.
Therefore, it is possible to reduce the capacity of the ice heat storage tank 4 as much as possible. In addition to this,
It can also adequately handle the morning starting road during heating.

のために利用される。 If there is no remaining heat in the ice heat storage tank 4 in the afternoon when the heating load is light, the system is switched to the circulation system shown in FIG. 6. That is, the three on-off valves 5i, 5j, and 5h shown in the figure are open, and the other on-off valves are closed, so that the medium from the compressor 3 is transferred to the second heat exchanger 2, and then to the expansion valve. Valve 6c, first heat exchanger 1
It circulates through sequentially. Therefore, the second heat exchanger 2 acts as a condenser and radiates heat, while the first heat exchanger 1 acts as an evaporator and absorbs heat. Thereby, the second heat exchanger 2 heats the room by exchanging heat with the air conditioner of the room (not shown). Further, at this time, the heat stored in the ice heat storage tank 4 is also used for heating the room.

It stores heat to keep running costs low.

抑えることができる。[Effects of the invention] As explained above, the air source heat pump system with an ice heat storage tank according to this invention has a first heat exchanger installed outdoors and a second heat exchanger connected to the indoor air conditioner. The heat medium is selectively and reversibly circulated between the exchanger and the ice heat storage tank connected to the room air conditioner using a compressor, so that the ice heat storage tank has sufficient capacity during cooling. On the other hand, during heating, the high heat stored in the ice heat storage tank and the low heat after use are used to effectively utilize the cold heat stored in the ice storage tank, which functions as a condenser.
Because the ice heat storage tank is configured to take out excessively high heat with high efficiency and use it together, the temperature range in which the ice heat storage tank can be used is dramatically increased, and the amount of heat stored at night can be increased accordingly. . From the above, it is possible to effectively use cheap late-night electricity as electricity for storing cold and hot heat in ice storage tanks, and as a result, the shift rate to late-night electricity throughout the year can be increased. This allows running costs to be kept low.

However, the heating function will not deteriorate due to insufficient heat storage in the ice storage tank.
また、暖房時に氷蓄熱槽と第２の熱交換器とを
