Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a thermocouple air conditioner that utilizes a heat pump cycle and a thermocouple.

(B) Conventional technology In the case of conventional air conditioners, which are the main type of air-cooled separate type air-conditioning air conditioners, there is an air-conditioning radiator, an indoor unit for the air-conditioning fan, an electric compressor, a radiator, and an outdoor unit for the blower fan. Among the units, outdoor units are installed outdoors, and the heat generated from the radiator is condensed during cooling or the evaporative cooling heat during heating is dissipated into the atmosphere as waste heat by forced air blowing by a blower fan. . However, in the case of heating, the heat in the atmosphere is used to raise the temperature with a refrigerant. In the case of a water-cooled type, a cooling tower, pump, and water piping are installed outdoors to cool the generated heat. The same applies to central type, packaged type, and dedicated air conditioners for cooling and heating.

(Q Problems that the invention aims to solve) As mentioned above, in the case of the main air-cooled separate type air-conditioning air conditioners, the heat generated from the air-conditioning radiator of the indoor unit, which is installed at a relatively high position, is used for air-conditioning and heating. This is done by blowing out cold or warm air using a fan, but since indoor heating and cooling are performed from the same air-conditioning and heating radiator, the hot air is blown out in a downward direction, especially during heating. It is difficult for the indoor temperature distribution to be uniform, and it is unlikely that a so-called cold-head-to-head temperature distribution can be expected.-In order to install the blade outdoor unit outdoors, holes must be made in the building for refrigerant piping to connect the indoor and outdoor units. In addition, because it is installed outdoors, it is exposed to wind, rain, and direct sunlight, making it susceptible to corrosion, damage, and external damage.
Particularly in the winter, snow, ice, cold air, etc. in cold regions such as Hokuriku, Tohoku, and Hokkaido make it difficult to install and operate fans, which cause malfunctions and require unnecessary consumption of electrical power, and waste heat is released into the atmosphere. The radiation has a negative impact on objects and people in the vicinity of the outdoor unit. Furthermore, since the radiator is cooled or heated with air in the atmosphere, it is directly affected by the outside temperature and has the disadvantage of being susceptible to fluctuations in heating and cooling capacity.

In the case of a water-cooled type, cooling towers, pumps, water piping, etc. are installed outdoors, which requires unnecessary consumption of operating power, and there are also problems such as maintenance, replenishment of lost circulating water, and securing water resources. There is.

Central-type, package-type, and dedicated air conditioners for cooling and heating have similar problems.

[Phase] Means for Solving the Problems In order to solve the problems, the present invention has been developed to replace the outdoor unit installed outdoors in the case of the conventional main type air-cooled separate type air conditioner with a relatively small indoor unit. Install it in a low position,
The radiator is used as a heating radiator, and at the same time, the conventional indoor unit, which is installed at a relatively high position, aims to equalize the indoor temperature distribution of each cooling and heating unit, and at the same time eliminates the blower fan of the conventional outdoor unit. The idea is to install a new thermocouple and recover waste heat through heat exchange, and at the same time, use the resulting thermoelectromotive force to supply electricity to the demand side, thereby saving electricity accordingly. .

In addition, in the case of water cooling type, conventional cooling tower, pump,
By abolishing water piping, installing new thermocouples and recovering waste heat through heat exchange, and at the same time using the resulting thermoelectromotive force to supply power to the necessary demand side, we can also save electricity accordingly. This is what we are trying to measure.

The aim is to solve these problems in almost the same way for central type, package type, and air conditioners dedicated to cooling and heating.

As a specific means, an electric compressor for refrigerant compression or an electric compressor with rotation speed control and a condenser (heating radiator)
Using a heat pump cycle consisting of a pressure reducer, an evaporator (cooling radiator), etc., or a high-performance, high-efficiency super heat pump cycle under development, both junctions of a thermocouple that combines different types of thermoelectric elements are A cooling fan or rotation speed that uses the evaporative cooling heat from the evaporator (cooling radiator), with a high-temperature junction that is heated and a low-temperature junction that is cooled, so that heat can be exchanged with the condenser and the evaporator. During cooling by blowing cold air using a controlled cooling fan, the high-temperature junction of the thermocouple exchanges the condensed heating heat from the condenser and recovers it for heating. This eliminates the need for outdoor installation or the installation of a forced air fan for this purpose, and at the same time, by creating a temperature difference between both junctions of this thermocouple, the thermoelectromotive force caused by the so-called Seebeck effect can be reduced. On the other hand, when a newly installed heating fan or rotation speed controlled heating fan uses condensed heating heat from the condenser (heating radiator) to blow hot air, evaporation from the evaporator is generated at the low temperature junction of the thermocouple. The cooling heat is recovered and cooled by heat exchange (however, at this time, heat exchange between the high-temperature junction of the thermocouple and the condenser is stopped).For this purpose, it is necessary to install it outdoors and install a fan for forced air. At the same time, by creating a temperature difference between the two junctions of this thermocouple, a thermoelectromotive force is generated due to the Seebeck effect, and the waste heat energy recovered from the thermocouple during cooling or heating is converted into electricity to generate electricity. The generated electricity is converted to direct current or alternating current to power the necessary demand side, such as an electric compressor or rotation speed controlled electric compressor, or other necessary parts (for example, indicator lights, cooling/heating fans, and even electric hot water). By supplying power or supplementary power to a water heater, etc.), it is possible to save the required driving power of the electric compressor or rotation speed controlled electric compressor or other required power by that amount.

In addition, as another means, there is a thermocouple 1 which exchanges the condensation heating heat of the condenser with its high-temperature junction and recovers it exclusively during cooling to create a temperature difference between both junctions and generate a thermoelectromotive force. ,
During heating, the evaporative cooling heat of the evaporator is exchanged with the low-temperature junction, and the thermocouple 2 is used to recover the heat and generate a thermoelectromotive force by creating a temperature difference between the two junctions. By using the system, cooling and heating can be separated and carried out by the evaporator (cooling radiator) and condenser (heating radiator), and by supplying power or supplementary power to the necessary demand side, It can also be timed to save energy.

Furthermore, as another method, in the case of an air conditioner dedicated to cooling or heating, the heat pump cycle and thermocouple are used to transfer the condensation heating heat of the condenser or the evaporative cooling heat of the evaporator to the high temperature junction of the thermocouple. Alternatively, at the same time as heat is exchanged with the low-temperature junction and recovered, the thermoelectromotive force generated due to the temperature difference between the two junctions is supplied to the necessary demand side or supplementally, so that electricity can be saved accordingly. You can also do it.

By using the above method, in the case of the main type air-cooled separate heating and cooling air conditioner, the cooling radiator and the heating radiator can be placed separately above and below, without having to install an outdoor unit or a fan for forced ventilation. Not only can conventional problems be solved by performing heating and cooling, but also power can be saved by effectively utilizing thermoelectromotive force generated by recovering waste heat from thermocouples.

Also, in the case of a water-cooled type, a cooling tower, pump,
There is no need to install water piping.

The same applies to central type and cage type air conditioners.

In addition, the reasons why outdoor units have traditionally been installed outdoors include the need for forced air flow using a blower fan, as well as constraints on the installation space indoors, and problems with the operating noise of the blower fan and electric compressor. However, these problems can be solved due to the elimination of the blower fan according to the present invention, the recent improvement in residential and office conditions, and technological improvements such as the reduction of electric compressor operating noise. However, if the operating noise ultimately becomes a problem, only the electric compressor should be installed outdoors. In the case of a water-cooled type, the present invention also eliminates the drain tower, pops, water piping, etc., as well.

Note that the heat pump cycle is a general term for the heat pump cycle or refrigeration cycle, and the high-performance, high-efficiency super heat pump cycle or super refrigeration cycle that is currently under development, unless otherwise specified. In addition, unless otherwise specified, the term "thermocouple" shall collectively refer to a single or multiple pairs of thermocouples and a high-performance/high-efficiency single or multiple pairs of extraneous couple that are under development.

In addition, unless otherwise specified, the term "air conditioner" collectively refers to air conditioners for cooling and heating, air conditioning only, and heating only.

(Equivalent action) In general, when a temperature difference is given between the two junctions of a thermocouple that combines different types of thermoelectric elements, the thermoelectromotive force E generated by the Seebek effect is E = a (Tt T2) (1)
α stands for thermoelectric power, and at present the value of α for semiconductors is about one order of magnitude larger than that for metals. T1 is the absolute temperature of the high temperature junction, T2
is the cold junction absolute temperature.

K is the electrical conductivity of the thermoelectric element material, and K is its thermal conductivity. Therefore, from equation (2), in order for a thermoelectric element to have high performance (i.e., 2 is large), it is necessary that the thermoelectric power α is large, the electrical conductivity C is large, and the thermal conductivity K is small. It possesses advantageous properties as a thermoelectric element material because of its large thermoelectric power and low thermal conductivity. In particular, compound semiconductors have advantageous conditions.

On the other hand, the maximum value of the heat-to-electricity conversion efficiency of the thermoelectric generation method due to the Savenok effect using thermocouples is currently M = 'J1 + Z (TI
+T2)/2 Also, Q is the condensation heating heat or evaporative cooling heat generated or absorbed per unit time from the condenser or evaporator of the heat pump cycle. If this is recovered by heat exchange with n pairs of thermocouples and the remaining condensation heating heat or evaporative cooling heat is Qn, then QIFQO(1-ηomax)"≦0.9"Qo
(4) If the recovery rate is about 90%, then from equation (4) #2
2, or approximately 22 pairs of thermocouples. Furthermore, the coefficient of performance of the heat pump cycle is approximately 3. Considering that in the case of a high-performance, high-efficiency super heat pump cycle, the number of thermocouple pairs is approximately twice that, it can be expected that the number of thermocouple pairs will be reduced. In addition, the number of thermoelectric elements is expected to be significantly reduced by the use of a thermoelectric element that has a dramatically superior thermoelectric figure of merit and the use of a superstatic couple that combines these elements.

Note that using multiple pairs of thermocouples in series has the advantage that the output (power generation amount) can be increased more than the output (power generation amount) obtained with one pair of thermocouples.

(F) Embodiment An embodiment of the present invention will be described based on the drawings. FIG. 1 is a block diagram of a thermocouple air conditioner using a heat pump cycle and a thermocouple, showing one embodiment of the present invention. In the figure, 1 is a thermocouple of a thermoelectric generator for recovering condensation heating heat or evaporative cooling heat, 3 is an electric compressor or rotation speed controlled electric compressor, 4 is a condenser (heating radiator), 5 is a pressure reducer, 6 is a is an evaporator (cooling radiator), and 7 is an accumulator. Reference numeral 8 denotes a heating fan or a rotation speed-controlled heating fan that radiates the condensed heating heat of the condenser (heating radiator) 4 into the room to perform heating.

On the other hand, 9 is a heat exchanger heated by condensation heating heat from the condenser 4, and is composed of, for example, a heat pipe. a is the high temperature junction of the thermocouple 1, and 1] is its low temperature junction.

, has the role of controlling heat transfer connection to the high temperature joint part 51,
An example is an electromagnetic two-way valve for a heat pipe, which has the function of closing and stopping its function during heating. At the same time, the heating fan 8 is stopped during cooling and can be driven during heating. ll+L and llb are different type (1) type [1 type, etc.] constituting the thermocouple 1, and are cooling fans or speed-controlled cooling fans that dissipate heat into the room and perform cooling.

On the other hand, 9' is a heat exchanger that is cooled by the evaporative cooling heat from the evaporator 6, and is composed of, for example, a heat pipe. 10' is the amount of evaporative cooling heat from the heat exchanger 9' to the low-temperature junction 1 of the thermocouple 1]
A heat transfer connector, such as a heat pipe, that transfers heat to the 1o'a and ■0'b open during heating to control the heat transfer of evaporative cooling heat to the low-temperature joints, and close during cooling to stop this function; for example, for heat pipes. It is an electromagnetic two-way valve. At the same time, the cooling fan 8' is stopped during heating and can be driven during cooling.

12 is a battery or a capacitor, 13 is a control unit, and 14 is a DC/AC converter (for example, an inverter 4C). However, if there is no need to convert to alternating current, the direct current converter 14 is not necessary. Reference numeral 15 denotes a regulator that adjusts and controls the main input to the electric compressor 3 from an external power source and the supplementary input of thermoelectromotive force from the DC converter 14 or the control unit 13.

Note that the evaporator above the condenser6. The heat exchanger 9.9' is selected to have the highest efficiency possible, and in the case of a super or heat pump cycle, a high performance electric compressor is selected. Thermoelectric elements (1121.111) are made of materials that have large thermoelectric power, high electric conductivity, low thermal conductivity, and excellent two-channel conversion characteristics, such as Bi2'To of the V-VI group of semiconductors.
a, B12 (TcSe) a system: B1Sb of V-V group
, Hi(Sl))2'l'cg system: other compound semiconductors are used. Furthermore, if technological development progresses and a supernatural couple made of materials with dramatically higher performance and efficiency is developed, it will be used. The solid joints a and b of the thermocouple 1 are made of metal (such as Cu), and heat is transferred to the thermoelectric elements 112t and 1113.
It also serves as an electrode.

However, when contacting semiconductors with metals, it is necessary to carefully consider the relationship between the work functions of each semiconductor and select the optimal metal material. If a more excellent and optimal material other than metal is developed in the future, we will use it. Further, the refrigerant used in the heat pump cycle is a single or mixed refrigerant such as freon or ammonia, but in the case of a super heat pump cycle, a mixed refrigerant or a non-azeotropic mixed refrigerant is used.

Next, in the case of cooling, the heating fan 8 is stopped and the cooling fan 8' is driven, and the electromagnetic two-way valves 10a and 101) are opened to perform the role of heat transfer connection. IQ/a10'+3 is closed and its role is stopped.

Electric compression, refrigerant compressed at a rotation speed of 3 is transferred to condenser 4
The condensed and liquefied heat is transferred to the heat exchanger 9, and the condensed heating heat is transferred to the heat transfer connector 10 and the electromagnetic two-way valve IQa.
, lQl+, the high temperature junction of the thermocouple 1; this is heated by heat transfer and recovered. On the other hand, the liquid refrigerant after heat radiation is reduced in pressure by a pressure reducer 5, flows into an evaporator (cooling radiator) 6, is evaporated and cooled, and the cooling fan 8' radiates the evaporative cooling heat into the room to perform cooling.

At this time, since the electromagnetic two-way valves 10'a and 10'b are closed, the evaporative cooling heat is not transferred to the low-temperature junction of the thermocouple 1 through the heat transfer connector lO'. Therefore, the evaporative cooling heat generated by the evaporator (cooling radiator) 6 is fully consumed for cooling. The vaporized refrigerant thus cooled flows into the accumulator 7 and returns to the intake side of the electric compressor 3, forming a heat pump cycle.

In the case of a high-performance/high-efficiency super heat pump cycle, the mixed refrigerant or non-azeotropic mixed refrigerant compressed by the high-performance electric compressor 3 is transferred to the high-efficiency condenser 4. Pressure reducer5. Evaporator 6
．． A super heat pop cycle is formed through other equipment.

On the other hand, 11 iL of thermoelectric elements of different types (P type, +1 type, etc.)
, 111), a temperature difference occurs between the conduction-heated high-temperature junction LL and the low-temperature junction)) of the thermocouple 1,
Thermoelectromotive force is generated by the Seebetsuk effect. The amount of power generated is determined by equation (1), and the generated DC power is stored in a battery or a capacitor 12, and the control unit 1
3. DC converter 14. Electric compressor 3 via regulator 15
Supplementary controlled power is supplied to the main power source along with the main power from the external power source, and the amount of main power supplied is reduced by that amount. In addition, direct current
If this is acceptable, the DC/AC converter 14 is not required, and power is supplied from the control unit 13 via the regulator 15 to the electric compressor 3 in a complementary manner together with the main power from the external power source.

Furthermore, when a high-performance, high-efficiency superstatic couple is used, the amount of condensing heating heat recovered is also greater, and the amount of generated thermoelectromotive force is also greater, so that the amount of power saved to the electric compressor 3 is also greater. The above explanation is an example of supplementary power supply to the electric compressor 3 by thermoelectromotive force generated by converting the energy of the recovered condensation heating heat into electricity, but other necessary demand side (for example, indicator lights,
DC/AC converter 14. Alternatively, it is performed via the control section 13.

Next, in the case of heating, it is carried out in the same manner as in the case of cooling described above.

That is, the heating fan 8 is driven while the cooling fan 8' is stopped, and the electromagnetic two-way valves 10'a and 10'+3 are opened to perform the role of heat transfer connection, and IQa,
101) is closed to stop its role. The refrigerant compressed by the drive of the electric compressor 3 flows into the condenser (heating radiator) 4, condenses and liquefies and radiates heat, and the heating fan 8 radiates the condensed heating heat into the room to perform heating, while the evaporator 6 The evaporative cooling heat is recovered by heat exchange to the low-temperature junction 1] of the thermocouple 1, and is cooled by heat transfer, and the temperature is increased between the high-temperature junction a of the thermocouple 1 and the low-temperature junction 1] which has been cooled by heat transfer. The thermal electromotive force generated due to the difference is supplied or supplementally supplied to the electric compressor 3 or other necessary demand side. For heating, there is 1 thermocouple
This means that the heat is used to raise the temperature with a refrigerant.

In the case of a rotation speed controlled electric compressor, the rotation speed is controlled by controlling the thermoelectromotive force generated by the thermocouple 1 together with the main power from an external power source (inverter control in the case of AC drive, Thyle-Screenard control, etc. in the case of DC drive). supplementary control power is supplied. In addition, a flow control valve (particularly f, not shown) is provided on the inlet or outlet side of each of the condenser 4 and the evaporator 6 to control the refrigerant to an optimum refrigerant flow rate corresponding to the rotational speed of the electric compressor 3 for synchronous control. By doing so, the refrigerant can be finely controlled to flow into the condenser 4 and the evaporator 6, respectively, and the thermoelectromotive force can be controlled and generated even more precisely.

FIG. 2 is a block diagram of a thermocouple air conditioner using a heat pump cycle and a 1°2 thermocouple.

In the figure, a thermocouple 1 that combines different types of thermoelectric elements 11'u,
The thermocouple 2 combined with I I'll exchanges the evaporative cooling heat of the evaporator 6 with its low-temperature junction b' and recovers it exclusively for cooling and heating, respectively, and collects it at each solid junction a.
, 1] Nil/137, the thermoelectromotive force generated by applying a temperature difference is supplied or supplementary power to the necessary demand side, thereby making it possible to save power by that amount. All other details are almost the same as in the case of FIG.

FIG. 3 is a configuration diagram of a thermocouple air conditioner exclusively for cooling using a heat pump cycle and a thermocouple. The outline is almost the same as the explanation for the case of cooling in FIG.

FIG. 4 is a configuration diagram of a thermocouple air conditioner exclusively for heating using a heat pump cycle and a thermocouple. The outline is almost the same as the explanation for heating in FIG.

In the embodiments shown in FIGS. 1, 2, 3, and 4, there are one pair of thermocouples or one pair of thermocouples, respectively. The condensation heating heat or evaporative cooling heat generated is recovered as much as possible, and a larger f
(Currently, multiple pairs of thermocouples are connected in series to generate thermoelectromotive force for power generation. The number of pairs is determined by the coefficient of performance of the heat pump cycle to achieve high performance and high efficiency. - This number also takes into account that in the case of a heat pump cycle, it is approximately twice that amount.

In the future, technological development of thermoelectric element materials with dramatically superior thermoelectric performance index will be carried out, and by using a superordinate couple that combines these new thermoelectric elements, the number of pairs will be greatly reduced, in some cases down to just one pair. Alternatively, it is expected that this will become possible by using one pair of transcendental couple.

FIG. 5 is a configuration diagram of a heat pump cycle during cooling of a conventional air-cooled separate type air-conditioning air conditioner. In the figure, 4' is the radiator of the outdoor unit, 5a is the heating pressure reducer, and 5
b is a pressure reducer for air conditioning, 6' is an air conditioning radiator for the indoor unit, 8'' is a blower fan for the outdoor unit, 8'' is an air conditioning fan for the indoor unit, 16 is a four-way valve, and 17 a is a check valve for air conditioning. , 17b is a heating check valve.

FIG. 6 is a configuration diagram of a heat pump cycle during heating in a conventional air-cooled separate type air-conditioning/heating air conditioner. In the figure, the only difference is that the flow of the refrigerant is reversed by switching the four-way valve 16, and everything else is substantially the same as in the case of FIG.

In the case of a conventional water-cooled type, the only difference is that a cooling tower, a pump, and water piping are provided in place of the blower fan of the air-cooled outdoor unit, and the rest is almost the same as the air-cooled type.

The same applies to conventional central type and package type air conditioners.

(0) Effect of the invention As explained above, the effect of the thermocouple air conditioner of the present invention is that the outdoor unit of the conventional main air-cooled separate type air-conditioning air conditioner is installed at a relatively low position indoors, and its heat dissipates. The air conditioner is used as a heating radiator, while the air conditioning radiator of a conventional indoor unit, which is installed at a relatively high position, is used as a cooling radiator, and by using these two radiators separately, each of them can be used for heating and cooling the room. Uniform indoor temperature distribution, especially during heating, without necessarily changing the direction of hot air blowing out, resulting in a temperature distribution that keeps your head cold and your feet warm. At the same time, heat exchange with a newly installed thermocouple allows waste heat to be generated. At the same time as recovery, waste heat energy due to the Seebeck effect is converted into electricity and the generated thermoelectromotive force is supplied or supplementary to an electric compressor or others on the demand side, thereby saving electricity accordingly. There is an effect that can be done. In addition, this eliminates the need for drilling holes in the building for refrigerant piping to connect the indoor and outdoor units when installing the outdoor unit outdoors, as well as the associated damage to the building and deterioration of airtightness. There is no corrosion or damage caused by wind, rain, direct sunlight, etc. during installation, or damage from the outside, and there is no problem of functional failure caused by snow, ice, cold air, etc., especially in winter, in cold regions such as Hokuriku and other parts of Japan, and Tohoku and Hokkaido. This will also extend the life of the air conditioner as a whole. Furthermore, waste heat dissipation from the heat generated by the heat radiator of the conventional outdoor unit eliminates the need for forced cooling or heating by installing a fan and the unnecessary consumption of operating power and maintenance, resulting in further power savings. At the same time, the radiator is cooled or heated using air in the atmosphere, which eliminates the disadvantage of being directly affected by the outside temperature and causing fluctuations in heating and cooling capacity.Also, waste heat is dissipated into the atmosphere. This eliminates pollution that has a negative impact on goods and people in the vicinity of the outdoor unit.

On the other hand, in the case of the conventional water-cooled type, waste heat is recovered by heat exchange with a newly installed thermocouple, and at the same time, the resulting thermoelectromotive force is used to supply or supplementary power to the necessary demand side. At the same time, the conventional cooling tower, pump, and water piping can be abolished. The power saving effect increases accordingly, replenishing lost circulating water, securing water resources,
All pollution problems will disappear.

Also, almost the same problem can be solved with conventional central type, packaged type, cooling/heating-only air conditioners.

Furthermore, the reason why the outdoor units of conventional air-cooled Severe 1~ type air conditioners are installed outdoors is that forced air is required to be blown into the atmosphere by a blower fan to dissipate the waste heat generated from the radiator. In addition to performance, problems such as indoor installation space constraints and the noise of electric compressor operation include the elimination of blower fans for recovering waste heat using thermocouples, the recent improvement in residential and office conditions, and the operation of electric compressors. These problems can be solved by technological improvements such as sound reduction. However, if the operating noise ultimately becomes a problem, only the electric compressor should be installed outdoors.

Also, in the case of conventional water-cooled systems, cooling towers, pumps,
This problem can be solved by abolishing water piping, and can be solved in the same way with conventional central type, packaged type, and dedicated air conditioners for cooling and heating.

- The equipment cost of a complete set of thermoelectric generators such as cryo-thermocouples can be kept to a minimum.
