For the fixed part price B, the used sales price calculation unit 22 calculates the price for each part that is not related to the operation status based on factors such as the installation year and the installation location, and adds the price for each part to the fixed part price. Price B is obtained. Parts that are not related to the operating conditions are, for example, frames and drain pans that cause deterioration over time or parts that look bad. The installation year and the installation location are included in the device management information stored in the device management database 9.

  The maintenance cost C is a cost required for maintenance work such as cleaning, filter replacement, fan belt replacement, etc. performed before selling the used indoor unit 2a and outdoor unit 2b. The maintenance cost C is calculated by analyzing past maintenance conditions and equipment operation data. The past maintenance status and facility operation data are included in the device management information stored in the device management database 9. The maintenance cost C may be a fixed amount.

(B)
In the above embodiment, the trade-in price is calculated by the trade-in price calculation unit 23 based on the device management information and the market related information, but the present invention is not limited to this. For example, the trade-in price calculating unit 23 may calculate the trade-in price by multiplying the used sales price calculated by the used sales price calculating unit 22 by a certain ratio (a trade-in rate). In this case, the trade-in price can be calculated more easily, and the trade-in price can be managed by a common trade-in rate.
(C)
Although the price calculation system 1 of the said embodiment is the structure containing the used product information management apparatus 6 which has the equipment management database 9 and the used sales price calculation part 22, apparatus management information and market related information are received from an external database. Once acquired, it is also possible to calculate the used sales price by a single used sales price calculation device. That is, the used sales price calculation device is based on equipment management information related to the operation of one or a plurality of equipment and market related information related to the market situation of equipment in the used goods sales market. Is calculated. The second-hand sales price calculation device calculates the second-hand sales price of equipment based on equipment management information and market-related information acquired from an external database, thereby calculating an appropriate second-hand sales price based on the operating state of the equipment. Can do.

  In the above embodiment, the system for calculating the used sales price of the indoor unit or outdoor unit of the air conditioner and searching for the used indoor unit or outdoor unit has been described, but the present invention is not limited to this. Instead, the price calculation system of the present invention can calculate the used sales price for the equipment whose operating state is constantly monitored.
