Technical information

As is well known, a compression heat pump is mounted on a vehicle. The power source of the heat pump is an internal combustion engine or a motor that also serves as a driving power source. Therefore, when a large amount of power is required to travel the vehicle, the power that can be used by the heat pump is limited, and conversely, when the power required for traveling is small, it can be used for a heat pump, etc. So-called surplus power increases. Since such power fluctuations and power required for the heat pump do not always match, it is preferable to store or cool the heat obtained by driving the heat pump when there is surplus power.

In this way, surplus power generated by the power source can be recovered in the form of heat storage or cold storage, and if the driving force of the heat pump required for cooling or heating is insufficient, Cooling or heating can be performed using the thermal energy stored in the material. In addition, when configured in this manner, the heat released from the condenser in the refrigeration cycle can be recovered, so that energy efficiency can be improved, and thus the fuel consumption of the vehicle can be improved.

The amount of heat stored in the heat storage device is increased by recovering the heat generated by the heat pump or the heat released from the condenser in the refrigeration cycle.

However, the amount of heat applied to the latent heat storage device, the amount of heat released from the heat storage device, or the amount of heat exchanged between the heat storage unit and the cold storage unit provided in the latent heat storage device. Cannot be recognized. In other words, the user related to the latent heat storage device cannot recognize the increase or decrease in the amount of stored heat and the amount of heat exchanged between the thermal storage unit and the cold storage unit.

For this purpose, the driver or the like who is driving the vehicle can recognize which driving device is using the power by using the energy flow display.

An example of this will be described below using thermoelectric elements 4 a, 4 b, and 4 c that generate the Seebeck effect and the Peltier effect.

In the thermoelectric element 4a, electric energy is generated due to the temperature difference between the outside air and the cold storage heat, or reheat energy is generated by applying a voltage to the electric power provided in the thermoelectric element 4a.

It is possible to know the amount of heat that is transferred from the cold energy of the heat storage device 1a to the heat storage device 1b.

On the other hand, a part of the heat stored in the heat storage device 1 b becomes cold through the thermoelectric elements 4 a and 4 b serving as heat input means and heat output means. Then, the cold energy converted from the heat of the heat storage device 1b moves to the heat storage device 1a, and the amount of cold stored in the heat storage device 1a increases. Here, in the case where the cold energy converted from the heat of the heat storage device 1b moves to the heat storage device 1a, the amount of heat to be moved is measured by sequentially measuring physical quantities such as the temperature and flow rate of the heat, and the change in the amount of heat with time The amount is calculated by calculating the amount of heat recycled as 1 2 d.

Figure 2 shows the calculation results of thermal energy and electrical engineering energy based on environmental information, thermal energy information, and electrical energy information. A block diagram for controlling the amount of light generated is shown. There are two types of notification means: acoustic means, visual indications, and electrical signals. The following examples describe the display of calculation results by visual indications.

Environmental information includes information such as outside air temperature and solar radiation. This information can be obtained by measuring physical quantities such as temperature and solar radiation with a thermocouple, solar radiation meter, etc. In addition, thermal energy information includes cold energy, heat recovery, storage, and consumption information. These information measures physical quantities such as temperature and flow rate using thermocouples, mass meter, etc. It is obtained by setting.

Therefore, the calculated amount of heat energy and electric energy can be known.

Figures 3 and 4 show the flowcharts for reading the environmental information, thermal energy information, and electrical energy information, and displaying the thermal energy and electrical energy. In step S 31, the measured environmental information, thermal energy information, and electrical energy information are read into the arithmetic device. Based on the information read in step S 3 1, in step S 3 2, the amount of heat energy and the amount of electric energy are calculated in the arithmetic unit. Next, in step S 33, it is determined whether or not there is a power generation amount of electric energy generated by the solar power generator 8.

When it is determined that electric energy is generated by the solar power generator 8, in the next step S 3 4, whether or not there is a necessity for heat conversion between the heat storage devices 1 a and 1 b between the heat storage devices 1 a and 1 b Is judged. The necessity of heat conversion between cold heat and warm heat is determined by measuring the heat storage amount and the cold storage amount in the heat storage device 1a.1b. Specifically, the temperatures of the cold storage material provided in the heat storage device 1a and the heat storage material provided in the heat storage device 1b are measured, and the temperatures of the heat storage material and the cold storage material are measured.

On the other hand, if there is surplus heat on the heat storage device 1b side and the amount of cold storage heat on the heat storage device 1a side is insufficient, heat is sent from the heat storage device 1b to the thermoelectric element 4b and converted to electric energy. Engineering energy is added to the thermoelectric element 4a, converted into heat energy, and stored in the heat storage device 1a. As a result, the cold and warm heat stored is converted into heat.
