Description of the Related Art Conventionally, in this type of cogeneration equipment, an auxiliary heat source device such as a boiler can cope with heat demand that cannot be satisfied only by the amount of heat stored in a heat storage tank, and it is not necessary to replenish heat to the heat storage tank. In order to respond to the power demand in the current situation, we will respond to the power purchase from the power company.However, the operation situation is that the auxiliary heat source device needs to be operated or the power purchase is needed. In addition, the user could not judge that even if the power was not purchased, the heat storage tank was storing more heat than necessary and heat loss due to heat radiation was large.

った。For this reason, in the conventional equipment, the user does not proceed with the use of heat in the situation where the operation of the auxiliary heat source device is required, or the situation where the power purchase is required or the power purchase is not reached. However, in situations where heat loss due to heat dissipation increases due to heat storage more than necessary, the user often promotes the use of electric power, and in this regard, the operation and purchase of auxiliary heat source devices and power purchase are reduced as much as possible. There is still room for improvement in minimizing heat loss and taking advantage of cogeneration's energy saving and operating cost advantages.

It is possible to let the user know that the operation of the heat storage is necessary, and if the heat storage tank does not reach the full heat state or the full heat state where the heat generated by the power generation can no longer be accepted when it can be covered. Heat is already stored, and it is necessary to purchase electricity for power use, or even if it does not lead to power purchase, it will store more heat than necessary in power generation for power use and release heat When the heat loss increases, the user can be notified.

It is possible to prevent the user from advancing the use of electric power in a situation where heat loss due to heat dissipation becomes large due to excessive heat storage even if it does not reach, thereby making it possible to operate the auxiliary heat source device and By reducing power purchase and heat loss due to heat dissipation, more efficient and economical operation can be achieved by utilizing the advantages of cogeneration in terms of energy saving and operation cost.
