For example, when the air conditioner selected by the air conditioner selecting unit 32 is an air conditioner, a fan heater, an electric stove, a hot carpet, and a kotatsu (all model names A), the following nine expected utility costs are calculated. That is, the expected utility cost for each of the air conditioner, fan heater, electric stove, hot carpet, kotatsu, air conditioner and fan heater, air conditioner and electric stove, air conditioner and hot carpet, air conditioner and kotatsu is calculated.

In the expected utility cost calculation unit 33, the planned operation time, the energy used in the information database, and the registered utility cost per hour (for example, a power charge unit price of 22 yen / kWh, a gas charge unit price of 150 yen / m ^3). From the kerosene unit price 70 yen / L), the expected utility cost is calculated. If the electricity unit price or gas unit price fluctuates over time depending on the contract plan with the power company or gas company, register the power unit price or gas unit price for each time zone, or register the contract plan. The expected utility cost is calculated at the unit price for each time period.

For example, the expected electricity cost M (yen) when the heating operation by the air conditioner (model name A) is performed for T minutes, when T ≦ 15, is the following using the power consumption energy and the unit price of power charge at startup. Calculated by (Equation 1). Further, in the case of T> 15, it is calculated by the following (Equation 2) using the power consumption energy at the start-up, the power consumption energy at the time of stabilization, and the power unit price. However, the power consumption energy at startup is X (kw), and the power consumption energy at stability is Y (kw).
Suppose that the electric power unit price is E (yen / kWh). When calculating the expected utility cost for a combination of an air conditioner and one other air conditioner, calculate the expected utility cost for the air conditioner and the expected utility cost for one other air conditioner separately, and add them together. Calculate the expected utility cost.
... (Formula 1)
... (Formula 2)

The comfort level calculation unit 34 (first comfort level calculation means) includes information about the scheduled driving time and the driving range, information about the immediate effect, sustainability of the information database, and the upper limit of the size of the air-conditioned space that is highly effective. Based on the above, the comfort level for each of or a combination of the plurality of air conditioners selected by the air conditioner selection unit 32 is calculated. Specifically, the comfort level for each of the plurality of air conditioners selected by the air conditioner selection unit 32 is calculated, and the comfort level for the combination of the air conditioner and another air conditioner is calculated. For example, when the air conditioner selected by the air conditioner selecting unit 32 is an air conditioner, a fan heater, an electric stove, a hot carpet, and a kotatsu (all model names A), the following nine comfort levels are calculated. Air conditioners,
Fan heater, electric stove, hot carpet, kotatsu, air conditioner and fan heater,
Comfort level is calculated for each of air conditioner and electric stove, air conditioner and hot carpet, air conditioner and kotatsu.

The comfort level calculation unit 34 evaluates the comfort level of the air conditioner by comparing the scheduled operation time with the transition time (the time for transition from the startup time to the stable time). The transition time is appropriately determined and is, for example, 15 minutes. FIG. 4A shows an air conditioner, a fan heater, an electric stove, a hot carpet, depending on whether the scheduled operation time is longer than 15 minutes, for example.
And it is the figure which evaluated the comfort of Kotatsu (all model name A). The evaluation of the comfort level is a point system, ◎ is 2P (points), ◯ is 1P, and Δ is 0P. This evaluation of comfort is based on information about the immediate effect and sustainability of the information database. For example, an air conditioner (model name A) will be described as an example. As shown in FIG. 3, the air conditioner (model name A) has poor immediate effect (evaluation Δ) and good sustainability (evaluation ◎). Therefore, as shown in FIG. 4A, when the scheduled driving time is within 15 minutes, that is, when the immediate effect greatly affects the comfort level, the evaluation becomes low (evaluation Δ), and the comfort level is 0P. It becomes. On the other hand, when the scheduled driving time exceeds 15 minutes, that is, when the sustainability greatly affects the comfort level, the evaluation becomes high (evaluation ◎), and the comfort level becomes 2P.

Further, the comfort level calculation unit 34 evaluates the comfort level of the air conditioner depending on whether the operation range is narrow or wide. FIG. 4B is a diagram in which the comfort level of an air conditioner, a fan heater, an electric stove, a hot carpet, and a kotatsu (all model names A) is evaluated depending on whether the operation range is a spot (narrow area) or the entire room (wide area). It is. The evaluation of the comfort level is a point system, where ◎ is 2P, ◯ is 1P, and Δ is 0P. This evaluation of the comfort level is based on information on the immediate upper limit of the information database, the sustainability, and the upper limit of the size of the air-conditioned space that is highly effective. For example, taking an air conditioner (model name A) as an example, the air conditioner (model name A) is not immediately effective (evaluation Δ).
Sustainability is good (evaluation ◎), and the upper limit of the size of the air-conditioned space that is highly effective is wide. Therefore, as shown in FIG.
As shown in b), when the driving range is a spot (narrow area), the evaluation is normal (evaluation ○
), The comfort level is 1P. On the other hand, when the operation range is the entire room (wide area), the upper limit of the size of the air-conditioning space that has good sustainability and high effect is wide, so the evaluation is high (evaluation ◎), and the comfort level is 2P. .

And this comfort level calculation part 34 calculates each comfort level of an air-conditioning apparatus by adding the evaluation result based on scheduled driving | running time, and the evaluation result based on driving range. For example, when the scheduled operation time is 1 hour (over 15 minutes) and the operation range is the entire room, the comfort level of the air conditioner and the fan heater is 4P, and the comfort level of the hot carpet is as shown in FIG. 2P, the comfort level of the kotatsu is 1P, and the comfort level of the electric stove is 0P. FIG. 5 is a quick reference table of the comfort level obtained by adding the evaluation result based on the scheduled driving time and the evaluation result based on the driving range.

In addition, the comfort level calculation unit 34 calculates the comfort level for the combination of the air conditioner and another air conditioner by the following (formula 3). For example, the planned operation time is 1 hour (more than 15 minutes)
When the operation range is the entire room, the comfort level of the air conditioner and the fan heater is the sum of the comfort level of the air conditioner (4P) and half the comfort level of the fan heater (2P).
6P.
(Comfort level of combination of air conditioner and other air conditioner) = (Comfort level of air conditioner) + 1/2
× (Comfort level of other air-conditioning equipment) (Equation 3)

The communication unit 35 supplies information from the server 3 to the terminal device 2 and at the same time the terminal device 2.
And information received from the network (Internet). The communication unit 35 may be, for example, a wireless LAN, ZigBee, bluetooth, optical communication, or the like.
