Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an improvement of a heat storage type heating device for heating.

Conventional horticulture greenhouse heating devices introduce the air inside the greenhouse, which has been heated by solar heat during the day, around the heat storage material, perform heat exchange (give heat from the air to the heat storage material), and store the heat at night. The air inside the Heuss, whose temperature has decreased, is similarly guided around the heat storage material for heat exchange (giving heat from the heat storage material to the air).
This is used to heat the air by raising the air temperature.

In such a heat storage type heating device, the phase change temperature of the heat storage material is set at 20'C to facilitate heat storage and heat dissipation.

It is necessary to keep the temperature to a moderate level. However, there are few single substances that can achieve this level of phase change temperature, and various additives are added to adjust the phase change temperature to lower it.
Stability 1 There is a gap in terms of price.

Therefore, a heat storage heating system for a house, which is a complete combination of a heat storage device and a heat pump, as shown in FIG. 2, has been proposed.

In FIG. 2, inside the heat storage device body 1 there is a heat storage material 2.
...is accommodated. One end of the heat storage device main body L serves as an inlet for the air in the heath, and the other end serves as an outlet for the air. ...There are three blowers arranged on the exit side. 1 Near the air inlet in the main body 1, there is an inlet side air heat exchanger (for example, a plate fin tube heat exchanger) 4 that functions as a condenser during heat storage and as an evaporator during heat radiation, and near the air outlet there is an evaporator during heat storage and an evaporator during heat radiation. An outlet side air heat exchanger (for example, a plate-fin tube heat exchanger) 5 serving as a condenser is arranged.

These inlet-side rigid air heat exchanger 4 and outlet-side air heat exchanger 5 have a four-way valve 6. Compressor 7 for compressing refrigerant gas
, an accumulator which is a container for protecting the compressor8.
A check valve directing the flow of refrigerant from the inlet air heat exchanger 4 to the outlet air heat exchanger 5 9. A throttle mechanism (expansion valve or capillary tube) provided in parallel with this check valve 9 is a reverse ratio valve 1 which directs the flow of the JO1 refrigerant from the outlet side air heat exchanger 5 to the inlet side air heat exchanger 4. A heat pump is constituted by this inverse ratio valve 11 and a throttle mechanism 12 provided in parallel.

Further, a vinyl duct 3 is connected to the air outlet of the heat storage device main body 1.

The house heat storage type heating device, which can be constructed from the above-mentioned members, is installed in the gardening house 14.

The operation of the heat storage heating device described above will be explained.

(1) During heat storage During heat storage, the inlet side air heat exchanger 4 acts as a condenser, and the outlet side air heat exchanger 5 acts as an evaporator. At this time, in the heat pump 1, the refrigerant is transferred to the compressor 7 and the four-way valve 6.
．． Inlet side constricted air heat exchanger 4. Check valve9. Aperture mechanism No. 2. Outlet side constricted air heat exchanger5. Four-way valve6. Accumulator8. It circulates through a cycle formed by the compressor 7.

The air inside the house 14, which has been heated to about 20 to 35° C. by solar heat during the day, is introduced into the heat storage device main body 1 by the blower 3. This air is compressed by the compressor 7 to become high temperature and high pressure, and is heated to a temperature of about 40°C by exchanging heat with the refrigerant gas guided through the four-way valve 6 and into the inlet side air heat exchanger 4. (Indicated by ■ in Figure 4(a)). On the other hand, the high-temperature, high-pressure refrigerant gas condenses (liquefies) while dissipating heat to the surrounding air in the air heat exchanger 4 on the inlet side, and expands in the throttle mechanism 12 in a manner that is contrary to history and becomes a low-temperature, low-pressure gas. The gas-liquid two-phase state is led to the outlet side air heat exchanger 5.

The heated air becomes a heat storage material 2. ... sent to the surrounding area.

Heat storage material 2. . . . and the temperature decreases as a result of heat exchange between the Heat given to the heat storage material 2° from the air is stored.

The air whose temperature has decreased is sent to the outlet side of the main body, and is cooled and dehumidified by exchanging heat with the low-temperature, low-pressure refrigerant led to the outlet-side air heat exchanger 5 (see Figure 4 (1). (shown inside).

On the other hand, the low-temperature, low-pressure refrigerant absorbs heat from the air, evaporates in the outlet side air heat exchanger 5, and is vaporized in the four-way valve 6. It passes through the accumulator 8 and is introduced into the conbrella v7.

The cooled and dehumidified air is blown into the chamber 14 through the vinyl duct 13.

Theoretically, as shown in FIG. 3, the amount of heat storage is determined by the heat storage material 2. ..., the air temperature before heat exchange, and the phase change temperature of the heat storage material. In addition.

In reality, the amount of heat storage is smaller than this area due to the effects of supercooling of the heat storage material and the heat exchange efficiency between the amount of heat storage and the air.

(11 Heat radiation time Heat radiation time (night)) The inlet side air heat exchanger 4 acts as an evaporator, and the outlet side air heat exchanger 5 acts as a condenser.At this time, by switching the four-way valve 6, the refrigerant is Compressor 7, four-way valve 6.

The air inside the house 24, which is lower in temperature than during the day, is introduced into the heat storage device main body by the blower 3.

This air is cooled and dehumidified by exchanging heat with the low-temperature, low-pressure refrigerant introduced into the inlet side air heat exchanger 4 (see Figure 4).
b) In the medium O'''C'C representation, the low-temperature, low-pressure refrigerant absorbs heat from the air, vaporizes in the inlet side blast heat exchanger 4, passes through the four-way valve 6, accumulator 8, and is compressed by the compressor 7. and becomes a high-temperature, high-pressure refrigerant gas.Furthermore, this refrigerant gas d
The air is introduced into the outlet side air heat exchanger 5 through the four squares.

Cooled and dehumidified air stores heat 12. The heat storage material 2. The temperature is raised by exchanging heat between the

The heated air is sent to the outlet side of the main body J.

The temperature is further increased by exchanging heat with the high-pressure refrigerant gas introduced into the outlet air heat exchanger 5 (indicated by θ in FIG. 4(b)). On the other hand, the high-temperature, high-pressure refrigerant gas is condensed (liquefied) while dissipating heat to the surrounding air in the air heat exchanger 5 on the outlet side, and further passes through an inverse valve 17 9 and expands in a throttle mechanism JO to a low temperature and low pressure. It becomes a gas-liquid two-phase state and is led to the inlet side air heat exchanger 4.

The air heated in the manner described above is blown into the house 14 through the vinyl duct J3 for heating. In addition,
The amount of heat that can be used during heating is the sum of the heat storage amount A shown in FIG. 3, the compressor input during heat dissipation operation, the blower input, and the amount of heat dehumidified from the air. Further, the heat radiation load is represented by the area of a portion B that is quadrupled by the temperature inside the greenhouse when heating is not performed at each time and the minimum maintenance temperature of the crops.

According to the heat storage type heating device for a house, as a result of adding a heat pump to the heat storage device, it is possible to increase the temperature difference between the heat storage material and the air during heat storage and heat radiation, making it easier to store and release heat. Therefore, a high temperature can be selected as the phase change temperature of the heat storage material. Therefore, it is not necessary to add various additives to the heat storage material made of a single substance so as to lower the phase change temperature, thereby making it possible to improve the stability of the heat storage material and reduce the cost.

However, with the heat storage heating system for a house shown in Figure 2, the amount of heat storage is insufficient because there is no sunlight and the temperature inside the house does not rise sufficiently, or when the outside temperature at night becomes too low and the heat dissipation load becomes large, the temperature inside the house decreases. It may not be possible to maintain it.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an in-house heat storage type heating device that can maintain the temperature inside the house even when there is no sunlight or when the outside temperature is extremely low. .

That is, in the heat storage type heating device for a house according to the present invention, air heat exchangers are provided respectively on the air inlet side and the air outlet side of the heat storage device and on the outside of the house.

These three air heat exchangers, compressor, four-way switching valve, and throttle device constitute a heat pump, and selectively turn on and off the blower for the air heat exchanger installed outside the house depending on the operating state. For example, it is turned on when there is no sunlight or when the outside temperature drops too much at night.

An embodiment of the present invention will be described below with reference to the fpI diagram.

In FIG. 1, there is a heat storage material 2 inside the heat storage device main body 2.
2 is accommodated. One end of the main body 2 of the heat storage device 1 serves as an inlet for the air in the Heuss, and the other end serves as an outlet for the air.
3 is placed. Further, an inlet side air heat exchanger (for example, a plate fin tube heat exchanger) 24 is disposed near the air inlet inside the main body 2, and an outlet side air heat exchanger 25 is disposed near the air outlet. Furthermore, a vinyl duct 26 is connected to the air outlet of the two main bodies 21. Each of the above members has been installed inside the gardening house 27.

An outdoor unit 28 is installed outside the gardening house 27, and inside the outdoor unit 28 is a four-way valve 29 for switching the direction of refrigerant flow between heat storage and heat radiation. Compressor 30 for compressing refrigerant. Accumulator 31, which is a container for protecting the compressor. A return valve 31 directing the flow of refrigerant from the inlet air heat exchanger 24 to the outlet heat exchanger 25. A throttling mechanism (
expansion valve or capillary tube) 32. Reverse IL valve 33 for directing the flow of refrigerant from the outlet air heat exchanger 025 to the inlet air heat exchanger 24. Throttle υ mechanism 3 provided in parallel with this reverse 1-hi valve 33
4 and an air heat exchanger 35 is installed outdoors. Each of these members operates as a heat pump between the inlet side air heat exchanger 24 and the outlet side heat exchanger 25 in the heat storage device main body 2 installed in the house 27. It consists of In addition, the outdoor unit 28
An outdoor blower 36 is provided for blowing outside air to the outdoor air heat exchanger 35.

The effects of the heat storage heating device described above will be explained.

(1) During heat storage During heat storage, the refrigerant in the heat pump is transferred to the compressor 30.
, four-way valve 29. Inlet side air heat exchanger 24, throttle mechanism 35
．． Outdoor air heat exchanger 36° check valve 32, outlet side air heat exchanger 25. It circulates through a cycle formed by a four-way valve 29, an accumulator 3, and a compressor 30.

■Heat storage dehumidification operation There is sunlight, and the air inside House 27 rises sufficiently. When heating the room, the outdoor blower 37 is stopped.

As a result, the outdoor air heat exchanger 36 does not function effectively as an evaporator, and the outlet side air heat exchanger 25 functions as an evaporator.

The air inside the house 27 heated by solar heat during the day is introduced into the heat storage device main body 2 by the blower 23. This air is compressed by the compressor 3° to become high temperature and high pressure, and is heated by exchanging heat with the refrigerant gas guided to the inlet side air heat exchanger 24 through the four-way valve 29. On the other hand, the high-temperature, high-pressure refrigerant gas is condensed (liquefied) in the inlet-side air heat exchanger 24 while dissipating heat to the surrounding air, expands in the throttle mechanism 35, becomes a low-temperature, low-pressure gas-liquid two-phase state, and is then further air-flowed into the outdoor air. Heat exchanger 36. It passes through the check valve 32 and is guided to the outlet side heat exchanger 25. In addition.

Almost no heat exchange occurs in the outdoor air heat exchanger 36.

The heated air is sent around the heat storage material 22.

The temperature is lowered by exchanging heat with the heat storage material 22.

The heat given to the heat storage material 22 from the air is stored 2 Otsu.

The cooled air is sent to the outlet side of the main body 21, and is cooled and dehumidified by exchanging heat with the low-temperature, low-pressure refrigerant introduced into the outlet-side air heat exchanger 25VC. On the other hand, the low-temperature, low-pressure refrigerant absorbs heat from the air, vaporizes in the outlet side air heat exchanger 25, and evaporates into the four-way valve 29. Combrera through accumulator 31? It will be introduced in 30.

The cooled and dehumidified air is blown into the chamber 27 through the vinyl duct 26.

(B) Heat Storage Operation When there is no solar radiation and the temperature of the air inside the Heuss 27 does not rise sufficiently, the outdoor blower 37 is operated.

As a result, the outdoor air heat exchanger 36 acts as an evaporator, and the outlet air heat exchanger 25 does not effectively act as an evaporator.

The air inside the Heuss 27 is transferred to the heat storage device main body 2 by the blower 23.
It will be introduced inside. This air is compressed by the compressor 30 and becomes high temperature and high pressure. It is heated by exchanging heat with the refrigerant gas introduced into the exchanger 24.

On the other hand, the high-temperature, high-pressure refrigerant gas condenses (liquefies) inside the air heat exchanger 24 on the inlet side while radiating heat to the surrounding air. l1
It expands in the mechanism 35 to become a low temperature, low pressure gas-liquid two-phase state, and is led to the outdoor air heat exchanger 36. The outside air introduced into the outdoor room 28 by the outdoor blower 37 is passed through the outdoor air heat exchanger 36.
exchanges heat with the low-temperature, low-pressure refrigerant inside. The temperature of the refrigerant in the outdoor air heat exchanger 36 rises slightly, and the refrigerant passes through the inverse IT valve 32 and is guided to the outlet side air heat exchanger 25.

The heated air is sent around the heat storage material 22.

The temperature is lowered by exchanging heat with the antagonist 122.

Heat given to the heat storage material 22 from the air is stored.

The air whose temperature has decreased is sent to the outlet side of the first main body 21, but the temperature of the refrigerant in the outlet-side blast heat exchanger 25 has increased slightly, so the heat '90. There is almost no dusting, and cooling and
Dehumidification is rarely performed (in the diagram corresponding to FIG. 4(a) Ic, the OcD portion 4 is almost absent). On the other hand, the refrigerant flows from the outlet side air heat exchanger 25 to the four-way valve 29. It is introduced into the compressor 30 through the accumulator 3.

Air is blown into the house 27 through the entire vinyl duct 26.

As mentioned above, if the heat storage operation (2) is carried out, the air at the outlet of the main body 2 will not be cooled more than necessary. If this operation is performed when there is no solar radiation and the air temperature within the Heuss 27 does not rise sufficiently, a larger amount of heat will be stored compared to the heat storage and dehumidification operation (2).

(n) During heat dissipation During heat dissipation (at night), the refrigerant in the heat pump is transferred to the compressor 30. Four-way valve 29
．． Outlet side air heat exchanger 25° throttle V machine $33. Outdoor air heat exchanger 36. Back valve 34, inlet side air heat exchanger 24. It circulates through a cycle formed by a four-way valve 29°, an accumulator 3, and a compressor 30.

0 heat radiation violation 5 If the night air temperature does not drop that much.

Stop the outdoor blower 37. As a result, the inlet air heat exchanger 24 acts as an evaporator, but the outdoor air heat exchanger 36 does not effectively act as an evaporator.

The air inside the house 27, which is lower in temperature than during the day, is introduced into the heat storage device main body 2 by the blower 23.

This air is cooled and dehumidified by exchanging heat with a low-temperature, low-pressure refrigerant introduced into the inlet side air heat exchanger 24. on the other hand,
The low-temperature, low-pressure refrigerant absorbs heat from the air, vaporizes in the inlet air heat exchanger 24, and passes through the four-way valve 29. Accumulator 31
The refrigerant gas is compressed by the compressor to become a high-temperature, high-pressure refrigerant gas. Further, this refrigerant gas passes through the four-way valve 29 and is introduced into the outlet air heat exchanger 25.

The cooled and dehumidified air is guided around the heat storage material 22, exchanges heat with the heat storage material 22, and rises in temperature.

The heated air is sent to the outlet side of the main body 2, and is further heated by exchanging heat with the still-temperature and high-pressure refrigerant gas guided to the outlet side air heat exchanger 25. On the other hand, the high-temperature, high-pressure refrigerant gas condenses (liquefies) while dissipating heat to the surrounding air in the outlet side air heat exchanger 25, expands in the throttling mechanism 33 and becomes a low-temperature, low-pressure gas-liquid two-phase state, and then the outdoor air Heat exchanger 36. The air is guided to the inlet side air heat exchanger 24 through the check valve s4km. Note that almost no heat exchange is performed in the outdoor air heat exchanger 36.

The high-temperature air that has been heated in the above manner is transferred to the vinyl duct 2.
Air is blown into the space 27 through the air vent 61 for heating.

0 Heat pump heating operation (heating operation using an outside air heat source) For example, when the night air temperature drops too much and the heat radiation load is large, the outdoor blower 32 is turned on. As a result, the inlet side air heat exchanger 24 does not function effectively as an evaporator, and the outdoor air heat exchanger 36 functions as an evaporator.

The outside air introduced into the outside & 28 by the outside air transfer unit 37 undergoes heat exchange with the low temperature, low pressure refrigerant 7 in the outside air heat exchanger 36. The temperature of the refrigerant in the outdoor air heat exchanger 36 rises slightly, and the refrigerant passes through the valve 34 and is guided to the inlet side air heat exchanger 24.

The air inside the house 27 is introduced into the main body 2 by the blower 23, but since the temperature of the refrigerant in the inlet side air heat exchanger 24 has risen slightly, almost no heat exchange takes place, and cooling and dehumidification are hardly performed. This is not done (in the diagram corresponding to FIG. 4(b), there is almost no @ part). on the other hand.

The refrigerant passes from the inlet side air heat exchanger 24 through the four-way valve 29° accumulator 31f, is compressed by the compressor 30, and further passes through the four-way valve 29 and is introduced into the outlet side air heat exchanger 25.

Air is guided around the heat storage material 22, exchanges heat with the heat storage material 22, and is heated up.

The heated air is sent to the outlet side of main unit 2.

The temperature is further increased by exchanging heat with the high-temperature, high-pressure refrigerant gas guided to the outlet side air heat exchanger 25. On the other hand, the high-temperature, high-pressure refrigerant gas condenses (liquefies) 8 while dissipating heat to the surrounding air in the outlet side air heat exchanger 25, expands in the throttling mechanism 33, and becomes a low-temperature, low-pressure gas-liquid two-phase state, which generates outdoor air heat. It is led to an exchanger 36.

The heated air is blown into the space 27 through the vinyl duct 26 to perform heating.

If the heat pump heating operation (2) is performed as described above, the air passing through the inlet side air heat exchanger 24' and being guided around the heat storage material 22 will not be cooled more than necessary. However, the heat dissipation load is large and the heat storage lid during the daytime is not enough, so when O heat dissipation operation is performed, the temperature inside the house is maintained at 1! Even in such a case, the temperature inside the house can be maintained with zero heat pump heating operation.

As detailed above, according to the heat storage heating device for a house of the present invention, by selectively turning on and off the outdoor blower depending on the operating state and operating the outdoor air heat exchanger, it is possible to operate the outdoor air heat exchanger when there is no sunlight during the day. Increases the amount of heat storage and increases the heat radiation load at night.

In cases where the amount of heat stored in the daytime is insufficient, the interior of the house can be effectively heated, and other remarkable effects can be achieved.
